Description
- This application is a continuation in part of co-pending U.S. patent application Ser. No. 09/065,780 filed Apr. 23, 1998.
- The present invention relates generally to a portable system for transporting fluids from a source of purified water or dialysate to individual dialysis machines in a dialysis clinic.
- It will be appreciated by those skilled in the art that present systems used for fluid delivery to dialysis machines in dialysis clinic pose problems due to limited space and incidence of bacterial contamination. Furthermore, these systems are installed as permanent fixtures, making them expensive to install, expensive to disinfect, expensive to repair, and expensive to replace. Presently used systems installed as permanent fixtures physically depreciate over time, without the tax advantage of financial depreciation allowed for non-permanent equipment.
- The prior art systems provide fluids from a fixed water treatment plant in one part of a building to the dialysis machines in another room. This distance requires that long “runs” be used to transport fluids from the water treatment facility to the dialysis machines. This means that the prior art systems use large runs of piping.
- It will be further appreciated by those skilled in the art that bacterial contamination is a common problem in presently available systems. Standard plumbing design and polyvinyl chloride pipes are commonly used. The use of PVC piping and solvent welding methods of joining and fabrication of existing fluid delivery systems results in the creation of cavities which cannot adequately be disinfected by conventional clean in place procedures used by dialysis clinics.
- It will be further appreciated that there is a broad range of PVC mixtures utilizing a variety of stabilizers and plasticizers which over time leach into the fluid stream, and that the interior pipe surface becomes pitted and more conducive to trapping bacteria and supporting bacterial growth.
- It will be further appreciated by those skilled in the art that present systems require a significant amount of space, restricting mobility within a dialysis clinic and making the use of more heat-resistant yet expensive tubing, such as polytetrafluoroethylene (Teflon®) tubing cost prohibitive. Instead the predominant current practice for dialysate distribution piping makes use of chemical clean in place disinfection in materials (e.g. PVC) which are incompatible with heat disinfection. Furthermore, present systems are piped in permanent structures; chaises or bulky consoles that do not permit easy access, repair or replacement.
- It will be further appreciated by those skilled in the art that heat disinfection means are preferable to chemical disinfection means in these systems. Chemical disinfectants presently in use include strong oxidizing agents. Residual disinfectant not adequately flushed from the system poses a hazard to patients. For example, a common chemical disinfectant, formaldehyde, has been shown to cause some repeat dialysis patients to develop antibodies to the N-antigens on the surface of their own red blood cells. The present invention facilitates the use of heat disinfection by providing materials of construction that can be operated at high temperature.
- It will be further appreciated by those skilled in the art that, despite the use of chemical disinfectants, present systems still experience problems with bacterial contamination. Regular assay for endotoxin in the system is required. Furthermore, multiple connection points and ready access to those connections makes current systems more susceptible to deliberate tampering by unauthorized personnel.
- What is needed then is a system which facilitates heat disinfection and eliminates solvent welded joints. This needed system must eliminate “dead legs” in the system. A “dead leg” is generally defined as a dead end length of pipe of greater than five pipe diameters in length. This needed system must decrease equipment surface area in the dialysis clinic, facilitating disinfection. This needed system must provide replaceable components which are easily installed, repaired, and replaced, yet protected from potential tampering by unauthorized individuals. This needed system must be capable of use without being attached to real property. This needed system must use quick disconnects to permit easy placement of components. This needed system is presently lacking in the prior art.
- A fluid transport system is provided for communicating a source of fluids to at least one fluid-requiring instrument. The system is particularly designed to communicate ultra-pure water and additives to a dialysis machine in a dialysis clinic.
- The system includes modular ductwork which includes a plurality of removable ductwork segments defining a secondary containment chamber. A plurality of conduits are received through the ductwork for carrying fluids from the source to the fluid requiring instrument. Any fluids leaking from the conduits are caught in the secondary containment chamber.
- Each conduit of the plurality of conduits may be made up of a plurality of removable interconnecting fluid conduit segments. Preferably the system includes interchangeable modules, with each module including modular ductwork made up of a plurality of ductwork segments, and with each module including a plurality of conduit segments which corresponds to the plurality of conduits. Each conduit segment has a detachable coupling on at least one end thereof.
- The system may be installed either on the wall of a room, or extending into the interior area of a room. Those portions of the system extending into the interior of a room are supported on columns which preferably include lockable casters to provide mobility of the support columns within the room.
- At various locations throughout the system stations are provided for connection of the system to a dialysis machine. Each connecting station preferably includes a first manifold block to which the conduits are directly connected, and a second manifold block which is connected to the first manifold block by a plurality of quick connect couplings. The second manifold block further carries a second plurality of quick connect couplings which are specifically designed for connection to a particular brand and model of dialysis treatment machine. The dialysis treatment machines may be quickly changed by disconnecting the second manifold block from the first manifold block, and replacing the second manifold block with another manifold block having quick connect couplings specifically associated with another type of dialysis machine.
- It is therefore an object of the present invention to provide a portable system for transporting fluids from a source of purified water to individual dialysis machines in a dialysis clinic.
- Another purpose of the present invention is the provision of a modular fluid transport system for communicating a source of fluids to at least one fluid-requiring instrument.
- Still another object of the present invention is the provision of modular fluid transport systems for dialysis clinics, wherein the system is made up of a plurality of interchangeable modules.
- And another object of the present invention is the provision of a modular fluid transport system which can be heat sterilized.
- Still another object of the present invention is the provision of a fluid transport system having quick connect stations for connection of a dialysis machine or other fluid-requiring instrument.
- Another object of the present invention is the provision of a quick connect station for a fluid transport system, wherein the instrument to be connected to the station can be disconnected and replaced without interfering with the flow of fluid through the system.
- Another object of the present invention is the provision of methods of installing a fluid transport system for a dialysis clinic.

- The structure shown in FIGS.1-12 is also shown and described in our co-pending U.S. patent application Ser. No. 09/065,780 filed Apr. 23, 1998, the details of which are incorporated herein by reference.
- Referring now to FIG. 1, a fluid transport system is shown and generally designated by the numeral10. The
system 10 transports various fluids from asource 12 to a plurality ofdialysis machines 14 in adialysis treatment clinic 16. - The
source 12 may either be a conventional built in place system for providing pure water and additives to the dialysis clinic, or more preferably it may be a portable system constructed in accordance with U.S. patent application Ser. No. 09/122,000 filed on Jul. 24, 1998, of Peterson, et al, entitled “Portable Water Treatment Facility”, the details of which are incorporated herein by reference. -
Source 12 is a system for producing water from a reverse osmosis purification system. It may also be a source of deionized water. - Those portions of the fluid transport system within the
dialysis clinic 16 include amodular ductwork 18 which preferably is made of a plurality of removable interchangeable ductwork segments such as 20 and 22.Ductwork 18 may also be referred to as a conduit housing. - In order to enhance the modular nature of the
system 10 and to minimize the time and labor required for assembly thereof, the longer length runs of theductwork 18 will preferably be assembled from a plurality of substantially identical interchangeable standard length ductwork segments such as 20 and 22. In order make corners, and to provide vertical segments, various shaped interconnecting ductwork fittings will be provided. Additionally to complete some installations it will be necessary to use some custom fabricated components. - At least some of the ductwork segments such as20 and 22 may be mounted on an interior face of a wall of the room which defines the
clinic 16. Other ones of the ductwork segments such as 23 are free standing segments extending from the wall into the interior of the room. The details of construction of the free standingductwork segments 23 are schematically illustrated in FIGS. 5 and 6. The freestanding ductwork segments 23 are supported on portable columns or stands 104 havinglockable casters 106 engaging afloor 108 of the room of thedialysis clinic 16. Also shown in FIG. 5 are vertical portions 110 ofductwork 18. - FIG. 6 illustrates two parallel runs of
ductwork 18 placed back to back with their connectingstations 68 facing outward away from each other, so as to provide plumbing, electrical and telecommunication utilities to adjacent rows ofdialysis machines 14 within the interior of the clinic. This is schematically illustrated in FIG. 12 by the twodialysis machines 14 schematically illustrated on opposite sides of theinterior ductwork segment 23. - FIG. 3 illustrates one
embodiment 18A of the ductwork which is an extrusion having first andsecond cavities - FIG. 4 illustrates another
embodiment 18B of the modular ductwork having first, second andthird cavities - FIG. 11 illustrates the manner in which two adjacent) ductwork segments such as20 and 22 may be structurally connected together.
- The extruded structural duct shapes of FIGS.3 or 4 include external channels such as 34 and 36. T-nuts 38 are slidably received in the
channels junction 44 betweenadjacent ductwork segments 20 and 22.Screws 46 extend through thestraps straps - FIG. 12 similarly illustrates two lengths of
duct 18 which are running in parallel and which are supported from each other, in a manner analogous to that further described below with regard to FIG. 6. In the embodiment of FIG. 12, astrap 48 encircles the twoparallel conduits 18, and thestrap 48 is connected structurally to the conduits with T-nuts 38 and screws 46 in a manner like that described for FIG. 11. - The extruded ducts of FIGS. 11 and 12 also provide a structural support for various associated equipment, which may be hung from
channels - As seen in the elevation view of FIG. 2, the
ductwork 18 preferably carries a plurality of generally parallel fluid conduits such as 50, 52, 54 and 56. For example, thefirst conduit 50 may carry purified water or dialysate fromsource 12. The second, third andfourth conduits source 12 or storage tanks and may include a drain connection for the removal of effluents from the machine. - In the embodiment illustrated in FIG. 12, one possible arrangement of the conduits within the
ductwork 18 is illustrated. In the embodiment of FIG. 12, the left-hand ductwork 18 carries twofluid conduits upper cavity 28, a thirdfluid conduit 54 in theintermediate cavity 30, and apower cable 58 andcommunications cable 60 in thethird cavity 32. - The
cavities fluid conduits secondary containment chambers fluid conduits - In the embodiment of FIG. 1, the conduits such as50, 52, 54 and 56 may each be a continuous length of tubing which extends through at least two adjacent ductwork segments such as 20 and 22.
- It will be understood that when the
source 12 and thedialysis clinic 16 are separated by a substantial distance, such as when thesource 12 is located on a different floor of the building or is otherwise located a substantial distance from theclinic 16, an initial segment 66 (See FIG. 1) of each of the fluid conduits may run freely through the walls, floors or other utility openings of the building, and need not be contained within themodular ductwork 18. These initial portions of conduit will preferably be relatively long lengths of flexible conduit, which are run from a spool of conduit. - Interspersed within the
ductwork 18 are a plurality of connectingstations 68. The connectingstations 68 may also be referred to as connecting plates or outlet plates. The connectingstations 68 are fluidly connected to the fluid conduits such as 50, 52, 54 and 56 and also to thepower cable 58 andcommunications cable 60. - As been seen in FIG. 7, the connecting
station 68 has first and second ends 70 and 72 and has afront surface 74. As best seen in FIGS. 5 and 6, the ends 70 and 72 are connected to theductwork 18. The connectingstation 68 includes a sheet metalouter housing 75 extending fromfirst end 70 tosecond end 72. Contained within thehousing 75 on the left portion thereof is a manifold block 94 as best seen in FIG. 7 which extends fromleft end 70 to a right end 96 of manifold block 94. A hollow housing portion 98 extends from right end 96 of manifold block 94 to theright end 72 ofhousing 75. - The various fluid conduits contained in the
ductwork 18 are connected to passageways formed through the manifold block 94 of connectingstation 68. The passageways typically are longitudinal bores extending fromfirst end 70 to second end 96. A plurality of outlet ports such as 77, 79, 81 and 83 communicate with the passageways and thus communicate with thefluid conduits outlet ports dialysis machine 14 via a bundle of flexible hoses schematically indicated as 76 in FIGS. 1 and 2. It will be understood that the hoses ofbundle 76 need not actually be bundled together, and they may be separate hoses. - Continuing with the description of the connecting
station 68 at FIG. 7, thecommunications cable 60 is connected tocommunications outlet 78 which includes a quick connect adapter for connection of thedialysis machine 14. Thedata communications outlet 78 may be utilized to connect thedialysis station 14 to a monitoring device of a central monitoring system. - Various monitors associated with the connecting
station 68 are connected to indicator lights such as 80, 82 and 84 which indicate whether the system is in a normal mode of operation, a disinfectant mode, or alarm mode. The disinfectant mode is indicated when hot water or chemical disinfectants are being flushed through the system. The alarm mode is illuminated when an abnormality in the operation of the system is detected. - The
power cable 58 is connected to apower outlet 86 on the connectingstation 68. - FIG. 8 is a schematic section view taken through the three outlet ports,79, 81 and 83, and shows the same connected to three of the passageways through
connector plate 68, which passageways are designated as 88, 90 and 92. As previously noted, thepassageways first end 70 to second end 96 of the manifold block 94, which is typically a solid block of a machineable material such as plastic. Thepassageways first end 70 to the second end 96. - The hollow housing portion98 of connecting
station 68 contains thecommunications outlet 78, the indicator lights 80, 82 and 84, and thepower outlet 86. - FIG. 8 only illustrates three
passageways connector plate 68. - The fluid conduits such as52, 54 and 56 are connected to the
passageways first end 70 and second end 96 of the solid manifold block 94. The section views of FIGS. 9 and 10 through the hollow portion 98 of connectingstation 68, schematically illustrate thefluid conduits passageways - As seen in FIG. 10, a
second power outlet 102 may be mounted in the upper surface of the hollow housing portion 98 of connectingstation 68. All outlets are integrally ground fault interrupt protected. - The various ductwork segments, such as20, 22, 23 and connecting
station 68 are releasably connected together to allow various components of thesystem 10 to be removed for service and disinfection. After removal, components such as the connectingstation 68 andductwork segments - The removability of the various components also aids in the ability to heat disinfect the components. Those components which are in communication with the fluids, and particularly the
fluid conduits - An alternative embodiment of the invention is illustrated in FIGS.13-24. A representative portion of this alternative fluid transport system is shown in schematic elevation view in FIG. 13 and is generally designated by the numeral 122. Like the
system 10 of FIG. 1, thefluid transport system 122 is designed to transport fluids from a source such as thesource 12 to a fluid-requiring instrument such as thedialysis machines 14. - There are several primary differences between the
system 122 of FIG. 13 and thesystem 10 of FIG. 1. First, thesystem 122 primarily utilizes relatively short rigid plastic conduit segments which are connected together by detachable couplings, which preferably are unions. Second, the outer ductwork of thesystem 122 is preferably formed of sheet metal rather than the extruded shapes of FIGS. 3 and 4; it is noted, however, that thesystem 122 may also use extruded ductwork like that described for thesystem 10. Third, the connecting station has been greatly modified to provide for a rapid changeout of a dialysis machine. In FIG. 13, the ductwork is not shown, so that the details of construction of those components within the ductwork may be seen. The details of the ductwork are more clearly seen in the cross sectional view of FIG. 24. - The
system 122 includes fivefluid conduits example conduit 124, includes a plurality of removable conduit segments, such as adjacent segments 134 and 136 of theconduit 124. Adjacent conduit segments such as 134 and 136 are joined by adetachable coupling 138 which is a conventional union with o-ring seals. As will be understood by those skilled in the art, the union has first and second parts 140 and 142 which will be fixedly attached, such as by plastic welding, to the adjacent pipe segment, and a rotating collar 144 which is used to connect the parts 140 and 142 of the union. - Also shown in FIG. 13 are a
typical elbow fitting 147 for making a right angle bend in thefluid transport system 122, and thetypical T fitting 149. - FIG. 14 schematically illustrates a portion of the system of FIG. 13 with the addition of
expansion joints 176 located in the first andfourth conduits - Much of the
fluid transport system 122 is defined by prefabricated standard interchangeable system modules such as indicated at 146 and 148. - Each system module such as146 includes a conduit segment such as 134 for each of the
fluid conduits 124 through 132. A detachable coupling such as 138 is attached to at least one end of each fluid conduit segment. - The
modular system ductwork segments 146 in convenient lengths. For example, a typicalmodular element 146 may have a length of approximately eight feet. The pipe conduit segments 134 will have male or female union connections on either end. The ductwork segments will have attachments for interconnecting with adjacent ductwork segments. - There can be lengths of the
system 122 in which thesystem modules station 150 for connection of one of the dialysis machines such as 14 shown in FIG. 2. The connectingstations 150 may also be referred to as connecting plates or outlet plates. - As was the case with the preferred materials for the
system 10 of FIG. 1, each of thefluid conduits 124 through 132 is preferably constructed from materials which are stable at a temperature of at least 105 degrees Celsius supplied for a period of at least twenty (20) hours, so as to facilitate heat disinfection. Each of the fluid conduits, and particularly each of the removable conduit segments is preferably constructed from polytetrafluoroethylene, polypropylene, or cross-linked polyethylene. - It has been determined that these materials are superior for use in a hemodialysis clinic, because they are less likely to give off contaminating gases, or to leach undesirable materials such as fillers, plasticizers, stabilizers, etc., as compared to the typical prior material polyvinylchloride. The use of these materials allows heat sterilization of the conduits in place within the
system 122. This may be accomplished by flowing hot fluids such as steam there through. This is particularly desirable for conduits used to conduct fluids in which bacterial growth is particularly a problem. In the case of a dialysis machine, this is particularly true for thefirst conduit 124 which typically conducts pure water and thefourth conduit 130 which may typically be used to conduct a bicarbonate solution. - Furthermore, each
system module ductwork 152 shown in FIG. 24.Ductwork 152 may also be referred to as a conduit housing. At periodic intervals the conduits 124-132 are supported from theductwork 152 by brackets such as 151. - The
ductwork 152 defines a single containment passageway orchamber 154 in which all of thefluid conduits 124 through 132 are received. Thelower portion 156 of thepassage 154 may be defined as asecondary containment chamber 156 for catching any fluids leaking from thefluid conduits 124 through 132. - In the cross-sectional view of FIG. 24 it is seen that the
ductwork 152 includes a base portion 158 and a cover portion 160. The base portion 158 includes a back wall 162 and a bottom 164 with an upward extendinglip 166 to define thesecondary containment chamber 156. - The cover portion160 includes a front wall 168, a top 170 and a downward extending
lip 171. The front wall 168 andlip 166 overlap and are held together by an S-shape clip 173 which runs along the length ofductwork 152. Thelip 171 and back wall 162 overlap and are held together by an S-shape clip 172 which runs along the length ofductwork 152. - The base portion158 of the
ductwork 152 is mounted on asupport 174 which may be a wall of the room, or which may be a vertical column support such assupport 104 seen in FIGS. 5 and 6. - At intervals along the length of the
conduits bracket 151 seen in FIG. 13. - The
ductwork 152 is preferably formed in prefabricated segments corresponding to the length and dimensions of thesystem modules stations 150. Theductwork 152 may include openings and access panels associated with the connectingstations 150 and with other components. - The ends of the pre-fabricated segments are joined together by H-
shape clips 153 as shown in FIG. 25. - The details of construction of the connecting
station 150 are best seen in the side elevation view of FIG. 19 which is a view taken along line 19-19 of FIG. 13. The connectingstation 150 includes afirst manifold block 176 which is directly connected to theconduits 124 through 132, and asecond manifold block 178 which is detachably connected tofirst manifold block 176 by first plurality ofquick connect couplings 180. - The
first manifold block 176 may also be referred to as a connector plate or outlet plate. Thesecond manifold block 178 may also be referred to as an adapter plate. - The details of construction of the
first manifold block 176 are best shown in FIGS. 15 and 16. Manifold block 176 is preferably constructed from a rectangular block of solid plastic material, preferably the same material from which the fluid conduits are constructed. Themanifold block 176 has front andrear surfaces - A plurality of
supply passages first end 186 to thesecond end 188. Adjacent each of theend walls 186 and 188 a counter bore such as 200 defines asocket 200 for receiving and end of an associated one of thefluid conduits 124 through 132. Thefluid conduits 124 through 132 are preferably connected to thefirst manifold block 176 by heat welding or other suitable technique to provide a rigid and permanent attachment. - The connections between the piping and the
sockets 200 on the manifolds such as 176 or theunion fittings 138 are preferably formed by socket fusion welding. Socket fusion welding is a technique by which the plastic is heated to the melting point within heating dies, and then the components to be joined are forced together. This technique is preferred because the potential for forming interstitial spaces, voids, cracks, etc., is minimized or eliminated altogether. Voids and cracks constitute sites for potential bio-growth and make dis-infection difficult. - Each of the
supply passages 190 through 198 tees into a short laterally extending portion intersecting thefront surface 182, which may be referred to as an interface surface so as to define a first plurality ofinterface ports front surface 182. - The second manifold block which is178 is best shown in the front and side views of FIG. 18.
Second manifold block 178 has afront surface 212 and arear surface 214. Therear surface 214 may be referred to as asecond interface surface 214, and thefront surface 212 may be referred to as anoutlet surface 212. - The
first manifold block 176 may be referred to as auniversal manifold block 176, and thesecond manifold block 178 may be referred to as aninterface manifold block 178. - The
second manifold block 178 has a plurality of intermediate passages such as 216, 218, 220, 222 and 224 defined therethrough from therear surface 214 to thefront surface 212. Each of theintermediate passages 216 through 224 intersects therear surface 214 at one of a second plurality of interface ports which are complementary to and aligned with theports 202 through 210. - The first plurality of
quick connect couplings 180 each include a first part 226 which is threadedly connected into one of theports 202 through 210 of firstmanifold block 176, and a second part 228 which is threadedly connected to the corresponding port in thesecond manifold block 178. - The
quick connect couplings 180, may for example be those manufactured and sold under the Parker, Colder, or Walther Prezision brands. - Those skilled in the art will be familiar with such couplings and will understand that they allow the
second manifold block 178 to be quickly disconnected from thefirst manifold block 176 without the loss of fluids from thefluid passages 190 through 198. As thequick disconnects 180 are disconnected, spring-loaded valves contained in each of the parts 226 and 228 close the flow passage there through. - Additionally, a plurality of threaded hose fittings230 (see FIG. 19) are connected to the
front surface 212 of thesecond manifold block 178 to provide for connection to the hoses of thehose bundle 76 from thedialysis machine 14. - The hose
interface manifold block 178 is not specific to any particular type of dialysis machine. Two additional examples of substitute second manifold blocks, specifically designed for use with specific dialysis machines, are shown in FIGS. 20 through 23. - FIGS. 20 and 21 are front and side elevation views, respectively, analogous to FIGS. 17 and 18, of an
interface manifold block 230 particularly designed for use with a Cobe brand dialysis machine. It is noted that on theback surface 232 of theinterface manifold block 230, there are found the second parts 228 ofquick connect couplings 180 which are identical in construction and arrangement as the second part 228 ofcouplings 180 shown in FIG. 19. Thus, the substituteinterface manifold block 230 may be substituted for theinterface manifold block 178 by merely disconnecting thequick connect couplings 180 shown in FIG. 19, and then reconnecting theinterface manifold block 230 of FIG. 21 in place of the originalinterface manifold block 178. - The
front surface 234 of the substituteinterface manifold block 230 carries various fittings such as 236, 238, 240, 242 and 244 which are specifically constructed for connection to the Cobe brand dialysis machine. - FIGS. 22 and 23 show front and side elevation views of yet another machine specific
interface manifold block 246 particularly designed for use with an Althin brand dialysis machine. Again, theinterface manifold block 246 carries quickconnect coupling portions 180, 228 on itsrear surface 248, which will interconnect the couplings on theuniversal manifold block 176. Again, thefront surface 250 carries a plurality of machines specific quick connect couplings designed for use with the Althin machine. - It is noted that FIGS. 21 and 23 are not true side elevation or section views, but instead they schematically illustrate the specific structure of the various couplings which are attached to the
interface manifold block - A connecting station like
station 150 shown in FIG. 19 including the first and second manifold blocks 176 and 178 with thequick connect couplings 180 therebetween provides several advantages. - Primarily, it allows the
dialysis machine 14 to be exchanged for adifferent dialysis machine 14 of a different make and model. Those skilled in the art will understand that each given make and model of dialysis machine typically has associated therewith its own machine specific group of quick connect couplings which are used to connect the dialysis machine to a station of a dialysis clinic. Two examples of different dialysis machines are the Cobe machine associated with the connectors of FIGS. 20 and 21, and the Althin machine associated with the connectors of FIGS. 22 and 23. In the prior art, a connecting station for a dialysis machine has typically been permanently installed in a rigid permanent wall and is suitable for connection only to one type of dialysis machine. If the machines used in a given clinic are changed, the entire system must be shut down and replumbed to provide suitable connections for the new machines. - With a connecting station like that shown in FIG. 150, the secondary manifold blocks178 may be constructed in a form which are specific to a given make and model of dialysis machine. The
first manifold block 176, however, is a universal design which need not ever be changed. - If it is desired to change the type of dialysis machine being utilized, all that need be done is to remove the
second manifold block 178 by disconnecting thequick connect couplings 180 and to replace thesecond manifold block 178 with another second manifold block which has quick connect couplings on itsfront surface 212 particularly designed for use with the new dialysis machine. - This construction for the connecting
station 150 eliminates what are known as “dead legs” within the piping system. Industry standards provide that in order to eliminate areas within the plumbing where fluids do not readily flow and bacteria may grow in stagnant fluid, there should be no portions of the conduit passageways in excess of five pipe diameters in length which do not have free flowing fluid therethrough. The use of the primary and interface manifold blocks with the quick connect couplings therebetween provides a manner of communication between thedialysis machine 14 and the fluid conduits which eliminates the presence of any such dead legs of greater than 5 pipe diameters in length. Furthermore, all of the components of the connection station may be readily removed and sterilized then replaced. - In FIG. 24 a slightly modified version of the
universal manifold block 176 is shown and generally designated by the numeral 252. Themanifold block 252 is similar to themanifold block 176 except for the addition of inline shut off valves such as 254 which lead from the passageways such as 190 to the outlet port such as 202. The shut offvalves 254 are simple 90 degree valves which are operated with a flat end screwdriver which may be inserted intoslot 256. - In FIG. 24, the
interface manifold plate 178 has not been shown, but it will be understood that it is mounted on themanifold block 252 in the same manner as shown in FIG. 19. The front wall 170 of thesheet metal ductwork 152 will have an appropriate cut out opening therein through which the front surface of theinterface manifold block dialysis machine 14. - Also shown in FIG. 24 is the preferred location for the
electrical power cable 58. Thecommunications cable 60 is also preferably located in the general area of thepower cable 58. - Either of the modular
fluid transport systems dialysis clinic 16. Thus the modularfluid transport system - Both the ductwork and the fluid conduits, and the various components such as the connecting
stations clinic 16 where they may be quickly assembled into the systems previously described. - By use of the preferred materials for the fluid conduits, the system may be heat sterilized in place by flowing steam or other hot fluids there through. Additionally, any particular portion of the system may be readily removed for off site sterilization.
- Repair of any portion of the
system - Also as previously described with regard to the connecting
station 150, use of that arrangement allows thedialysis machines 14 to be easily exchanged for different models and makes of machines. - The use of the
system dialysis machines 14 within theclinic 16. With prior art built in place systems, this was not possible without tearing down walls, modifying or replacing chaises and replumbing a system. With the system of the present invention, the plumbing and outlets may be quickly rearranged by merely changing out various components. - Although the
systems - Thus it is seen that the apparatus of the present invention readily achieves the ends and advantages mentioned as well as those inherent therein. While certain preferred embodiments have been illustrated and described for purposes of the present disclosure, numerous changes in the arrangement and construction of parts and steps may be made by those skilled in the art, which changes are encompassed within the scope and spirit of the present invention as defined by the appended claims.
