Description
2~940-518 The presen~ invention relates to a valve-provided tube connecting device to be connected with a liquid line intended to be connected to a patient either for draining of body liquids, e.g. in relation to collection of urine or surqical draining, or in the delivery of liquids in different infusion systems. A purpose of the invention is to achieve an effectively closed system to minimize the risk of bacterial infections, at the same time as the risk of spillage is minimized.
Catheters are used as devices for patien~s who temporarily or permanently have lost their ability to control the urine draining from the urinary bladder. Such catheters are connected to a urinary drainage bag with a welded tube and a connector of variable length. The drainage bag is thus exchanged at different intervals of time depending on the produced amount of urine, normally 3-4 times per day. The bag exchange is done by using a clip which is closed on a point above the disconnecting point in principal to prevent leakage, and thereafter the bag is disconnected. However, this method suffers from several serious defects. The most grave defect is the discontinuatlon of the closed system and the strong increasing of the risk of intraluminar bacterial growth. The rlsk of spillage is great in spite of the clip, which ma)ces the process a "slnppy" operation.
Previously in EP 0 080 379 a connector assembly for use in drainage system of body liquids consisting of a valve-provided socket part and a valve-provided plug part which are plugged together has been described.
Summa.rv of the Inventlon The present invention provides a valve-provided connecting device to be connected with a liquid line intended to be connected to a patlent for dra.ining body fluids, comprising a drip chamber housing and a connectiny housing downstream of the drip chamber housing and suitable for connection with a connector, characterized in that said connecting housing contains a valve body comprising a conical upper seal, a solid conical lower seal, and a guide connecting the upper and lower seals; wherein the gulde and seals are fixed in a radial direction and moveable only in an axial direction; a spring acting on the valve body for urging the seals into a closed position; and wherein the valve body includes a part which is engageable with a connection for moving the moveable guide and seals into the open position when a connector is connected to the connecting housing.
The connecting device effectively maintains the system closed to be opened by closing the inlet upon either the disconnection of a drainage bag or at the connection of an infusion system. In that way the risk of bacteria and other contaminants entering and multiplying inside the system with consequent dangerous and expensive bacteria infections is decreased. Such a closed system would save a lot of human pain at the same time reducing the cost of health service as a result of fewer patient infections. The present connecting device minimizes the risk of spillage and facilitates the unpleasant operation of the handling liquids such as urine.

The connecting device consists of three units:
a drip chamber house (l) preferably with a non-return valve (4), a connecting house (2) with a spring loaded valve body (7) located down-stream from the drip chamber house (l), and a connector (3) designed for connection with the connecting house (2).
The following description only exemplifies the invention in more detail and illustrates a suitable embodiment within a suitable field of use, but it is not a restriction of the invention.
A detailed descrietion of the figures and the connecting device Referring first to Figure 5, there is shown a connecting device accord-ing to the invention. The connecting device consists of a drip chamber house (l) and a connecting house (2) to which connector (3) is con-nected. The drip chamber house (l) is connected at the upper end to a plug-provided inlet tube (20) which is used for drainage of body liquids, espec;ally urine. At the lower end of the connecting device, the connector (3) is connected to a drainage bag (21).
The drip chamber house (l) is made of, e.g., transparent plastic, and, as shown in Figure l, is provided with a grooved socket (24) at the top to which the plug part of the inlet tube (20) can be attached. In the upper part of the drip chamber house (l) is located a non-return valve (4) to control the flow of the drainage liquid. The non-return valve (4) is preferably made of elastic, thin-walled silicon rubber.
~L~ L7 9 0 The non-return va1ve (4) (Figs. 4A and 4B) has a collar (15) at the top which acts as a sealing-ring with the plug on inlet tube (20). The collar (15) also acts to suspend the non-return valve (4) in position within the drip chamber house (1). At the bottom of the non-return valve (43 is a narrow opening (16).
The lower end of the drip chamber house (1) is joined to the upper end of the connecting house (2) by, e.g. ultrasonic welding or gluing. At the cylindrical upper end of the connecting ~ouse (2) there is an aperatured spring holder (5) e.g. a spider which is preferably made of plastic. One end of a spring (6) is fastened to the underside of the spring holder (5). The other end of the spring (6) presses against a valve body (7) located within the connecting house. The valve body (7) is made of an elastic material, preferably silicone rubber. The valve body t7) (Figs. 3A and 3B) consists of a frusto-conical upper part (8), and a conical lower part, the foot (12). The upper frusto-conical part (8) consists of two sections, one thin-walled upper section (9) and one solid lower section (10). Guide parts are attached to the lower section (10) above the foot (12) and are fixed in radial direction and slideable only in axial direction.
The guide parts (11) can be designed in different ways e.g. in the form of projecting wings i.e. vanes from a central core e.g. a spool or in form of a solid core provided with channels inside, wherein the liquids can flow. The projecting wings can be 2, 3, 4 or even more in number, preferably 3 or 4. The function of the guide parts (11) are to guide the valve body (7) straight upwards by sliding against the vertical interior walls of the connecting house (2), while permitting liquid passage. In the lower part of the connecting house are an outlet (22) for the liquid passage and grooves (19) for connecting with the project-ing guide pins (18) of the connector (3) of the bayonet socket. The connector (3) is hollow and it is preferably made of plastic. Inside it is provided with a central pin (17) mounted on a spider means e.g.
a crossbar, in order that the liquid passage is not prevented. The out-let at the bottom of the connector (23) opens in a drainage bag (21)for instance by attaching the lower tube formed part of the connector to a welded tube of the bag. A sealing ring (13) can be placed in the 1~'7~L'~9~3 lower part of the connecting house or alternatively a sealing ring (14) can be placed along the cylindric interior surface of the connector.
It is also possible that both sealing rings (13) and (14) exist simul-taneously, to prevent leakage between the connecting house and the con-nector in assembled position. At the same time, the sealing rings bringabout a slight prestressing when the bayonet socket is in connected position.
The connecting device according to the invention is in principle intend-ed for non-recurring use. Accordingly, it is suitable that the drip chamber house (1), the connecting house (2), the connector (3) and the spring holder (5) be made of a plastic material e.g. an injection moulded thermoplastic such as styrenacylic nitrile (SAN). The drip chamber house is best made of a transparent plastic. The non-return valve, the valve body and the sealing rings are made of a soft, elastic, sealing material e.g. silicone rubber, and they are manufactured in one piece by injection mou1ding or cas~ing. The spring can best be made of stainless steel.
The drawings show the best way to carry out the invention as is antici-pated today. The design of the valve-provided connecting device can be varied within the scope of the following claims and the idea of the invention.
The connecting device functions in the following way in unassembled i.e. closed eosition (Fi~. 2) _ Three sealing zones exist in the connecting house (2) in unassembled position. The conical upper part of the valve body (8) seals against the connecting house in two different ways. The sealing is effected, partly by the drainage liquid pressing the thin-walled upper section (9) of the conical upper part of the valve body against the conical interior walls of the connecting house (25), and partly by pressing of the spring (6), which is installed in the lower part of the spring holder (5), against the interior bottom surface (26) of the solid lower section of the conical upper part of the valve body. A further sealing zone is the foot of the valve body (12), which by transmission of the ~L~7~L7~D
spring pressure through the conical solid section and the guide part to the foot closes the outle~ at the bottom of the connecting house (22~ by the conical foot (12) lying close to the conical walls in the lower outlet of the connecting house.
The connecting device functions in the following way in assembled l e oeened eosition (Fi~ 1) When the guide pins (18) of the connector are entered and are locked in the grooves (19) of the bayonet socket of the connecting house, the following happens:
The system is opened by pressing the ~oot (12) of the valve body upwards with the central pin (17) of the connector. The whole valve body is guided straight upwards by sliding of the guide part (11) against the vertical interior walls of the connecting house. At this time the outlet (22) at the sealing zones is opened to permit liquid passage.
The way of the liquid through the connecting device is the following:
The drainage liquid from the inlet tube (20) comes inside the drip cham-ber house (1) by the non-return valve (4). From there the liquid passes through the apertures in the spring holder (5) streams down and gets into and beside the elevated valve body. The liquid continues down through the slit between the conical upper part (8) of the valve body and the conical interior walls (25) of the connecting house and through the channels (grooves) which exist in the guide part (11) and out through the outlet of the connecting house (22) which is opened, since the foot of the valve body has been pressed up. Then the liquid passes down through the hollow connector (3) and out by the lower outlet of the connector (23) out in the drainage bag (21).
Figures 4A and 4B show the non-return valve.
Figure 5 shows a view of the connecting device inserted in a drainage system in outline.
