DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to FIGS. 1 to 5 of the drawings in detail, there is shown a nebulizer which generally comprises a container 10 having an inlet section 11 and an outlet section 12, both at the top of the container.
The inlet section 11 (FIG. 3) comprises a cylindrical column 14 extending upwardly from the container having a neck portion 15 at the upper end thereof, a body member 16 seated in the neck portion, a combined inlet fitting and cap closure 17 having a nozzle 18 for connection of a tube 19 for supplying air, oxygen or any other inhalable gas, and a coupling 20 for screw-threadedly securing the inlet fitting 17 on the neck portion over the body member 16. The inlet fitting 117 may be discarded in some instances and the coupling 20 used instead.
The body member 16. has a central bore 21 in fluid flow communication with a bore 23 of the inlet fitting 17 at its upper end, and has inserted therein at its lower end an aspirating and nebulizing assembly 22 (FIG. 5).
As best shown in FIGS, the assembly 22 has an upper bore section 24 terminating in a downwardly facing nozzle 25 at its lower end, and has a lower bore section 26 terminating in a nozzle 27 at its upper end which nozzle is positioned crosswise and adjacent to the nozzle 25. The assembly further has a baffle 28 directly beneath the nozzles andhas a siphon tube 29 inserted into the lower bore section 26 and extending to the bottom of the container (FIG. 1).
When a gas under pressure is introduced into the bore 23 of the inlet fitting 17, a blast of gas is directed across the nozzle 27 by the nozzle 25. This causes eduction of fluid in the container through the nozzle 27 in the form of an aspirated spray. This spray is caused to impinge upon the baffle 28 by the blast of gas discharged from the nozzle 25 which in turn impinges upon the surface of the fluid and the container wall to nebulize the spray to amicron size suitable for inhalation.
The outlet section 12 (FIG. 4) comprises a covered cylindrical column 30 extending upwardly from the container 10, a vertical tubular section 31 on the top of the column 30, and a horizontally extending tubular portion 32 to which may be attached a nasal cannula or catheter (not shown) for insertion into a nostril.
The container 10 and its integral outlet section 12 and the inlet fitting 17 are formed of a plastic material which can be readily cut by scissors. The nozzle 18 of the fitting 17 has a formation 36 at its upper end (FIG. 1) for sealing the same. The horizontal tubular portion 32 likewise has a formation 37 for sealing the same. Additional openings may be provided by rupture of blisterlike end formations 39 and 40 of thinner plastic material on the inlet and outlet section columns 14 and 30 respectively, for purposes to be described hereinafter. After placing sterile liquid L into the sterile container 10 and sealing the inlet fitting 17 onto the neck portion 15, the device is completely sealed, so that the liquid cannot be contaminated.
When the device is to be used, the inlet formation 36 is cut away and the outlet formation 37 is likewise cut away, as by scissors 41, after which one end of a tube, such as a cannula or catheter (not shown) is telescoped over the tube 32 and the other end inserted into a persons nostril. An inhalable gas is delivered by the tube 19 through the bore 23 of the inlet fitting 17 and aspiration and nebulization take place as already described. The nebulizedliquid is discharged through the tubular portion 32 which has been opened at the outlet formation 37.
There are shown three blister formations 39 (see FIG. 2) on the inlet section column 14 and these function as venturi or air suction openings when out. When an inhalable gas, such as oxygen is delivered by tube 19 or coupling 20, the concentration of oxygen with respect to air discharged may be varied, depending upon whether three, two, one or no formations 39, respectively, are cut.
There is shown one blister formation 40 (see FIGS. 1 and 2) on an annular protuberance 42 of the outlet section column 30 and this blister formation 40 is provided as a cutable surface to enable the scissors 41 to be readily inserted therethrough, so as to cut away the entire upper portion of protuberance 42 including tubular section 31 and tubular portion 32, after which the opened section of protuberance 42 is connected for face mask or hood application. The contents of the container are administered to a single patient and the entire device is discarded when treatment of the patient is completed or when the entire contents of the container have been discharged.
in FIG. 6, the formation 37 of the tubular portion 32 has been cut away and a coupling 42 having a whistle 43 thereon is shown connected to the portion 32. The coupling 42' has an outlet 44 for discharge of the nebulized preparation and the whistle 43, which includes a check valve, serves as an audible alarm to indicate that the outlet 44 of the device has encountered a blockage, so that the attendant is immediately alerted to this condition.
In FIG. 7, there is shown a humidifier for inhalable gas which comprises a container 50 for a liquid having an inlet section 51 and an outlet section 52 on the top thereof, a flexible tube 54 having one end connected to the inlet section 51, and a porous gas diffusing element 55 resting on the bottom of the container and being attached to the other end of the tube 54.
The inlet section 51 includes a nozzle 56 for the connection of a gas supply tube 57 and a formation 58 for sealing the upper end of the nozzle 56.
The outlet section 52 includes a vertical tubular section 59, and a horizontal tubular portion 52 having a formation 37 for sealing the same.
The container 50 and its integral outlet section 52 and the inlet nozzle 56 are constructed of thin plastic material which enables the sealing formations to be readily cut away.
In use, the inlet formation 58 and the outlet formation 37 are cut away and the gas is introduced into the inlet nozzle 56. The gas is directed through the tube 54 to the element 55 which diffuses the gas. The diffused gas, as it rises through the liquid, is humidified and is discharged from the device.
Here again the device is completely sealed before use and is discarded after use, as already described.
From the foregoing description it will be seen that the present invention provides an improved fluid dispensing device which cannot be contaminated prior to use and being inexpensive is discarded after use.
