Alfred A. Med/oak 1N VEN TOR.
United States Patent Ofitice Re. 25,107 Reissued Jan. 2, 1962 25,107 SHOWER SEAT Alfred A. Medlock, East Point, Ga., assignor, by mesne assignments, to Safety Bath International, Inc., Atlanta,
Matter enclosed in heavy brackets appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.
This invention relates to a new, portable shower especially useful in hospitals and old age homes where bathing of invalids in a tub or shower has been found dangerous and/or difficult, but which is capable of. a more general application.
The invention entails a portable shower bath which is principally, although not exclusively, designed to facilitate bathing of invalids and persons who have become feeble or incapacitated. The need for such an article is quite prevalent especially in homes for aged where many old members, some of them bedridden, are unable to bathe for long periods because of the danger of suffering an accident on getting in and out of a tub or shower. Their weakened condition makes this dangerous.
The new shower, which rolls on wheels and can be connected to any water supply, may be rolled to the bed side of a patient so that even an injured person can, with care, be placed inside the compartment of the portable shower and enjoy the comfort and accompanying therapeutic value of a shower. The invention will be of invaluable help in hospitals and nursing homes and also to people caring for a sick or invalid member of the family in private homes.
The shower consists generally of a cabinet that has a contour seat in it which is capable of being moved in four directions by means of two hydraulic lifts. The motion is forward, backward, up or down to accommodate the height of the occupant and to facilitate the entrance and exit of the bather. The lifts are operated entirely by water pressure from the ordinary water line thereby necessitating no additional source of power insofar as seat adjustment is concerned.
It is preferred that the shower be equipped with a needle shower system which, besides being used to bathe a patient, can be used for hydro-therapy treatments. By disconnecting the shower from a water outlet the bottom of the compartment can be filled with whatever chemicals are needed for therapy. The invention has a small pump to circulate the mixture through the showering system for several reasons, one of which is to disinfeet the entire interior of the shower after it is used.
To care for the problem that exists when the hot water supply is exhausted or there is no such supply available, a small heater is operatively connected in the hydraulic line to preheat the water for the patient, for cleaning the interior of the shower or for any other reason.
Accordingly, an object of the invention is to provide a new and improved portable shower by which to bathe and treat patients or non-patients. 7
Another object of the invention is to provide a portable shower which is of practical construction and which is easily used, fulfilling a definite need and demand which exists at the present time.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which FIGURE 1 is a perspective view of a shower constructed in accordance with the invention.
FIGURE 2 is a rear view of the invention.
FIGURE 3 is a sectional view taken on the line 33 of FIGURE 1.
FIGURE 4 is a sectional view taken on the line 4-4 of FIGURE 3.
FIGURE 5 is a sectional view taken on the line 5-5 of FIGURE 3.
FIGURE 6 is a largely schematic perspective view showing the hydraulic flow system of'the shower.
:In the accompanying drawings there is a portable shower 10 that exemplifies the invention. This shower is constructed of a cabinet 12 that has an opening 14 in its front and a door 16 covering only the lower part of the opening. When the door is opened, by releasing latches 1S and swinging about the door supporting hinges 20, the entire front of the cabinet is open to facilitate the entry or exit of a patient who would be seatedon contour seat 22. The upper parts of the front edges of the cabinet are sloped rearwardly so that the patient or occupants head and arms are free of the cabinet although the patient may at his own choice and discretion put his arms into the cabinet.
As shown in FIGURE 3 the cabinet has a bottom 26 which slopes gently to form a sump 28. This is to facilitate drainage through drain line 30 controlled by manual valve 32. Both the sump 28 and valve 32 are optional features. The top wall 36 of the cabinet has a contoured recess 38 for the neck of the occupant and supports a group of control handles that are on conventional valves. No special valves were needed nor used in the shower, each valve being commercially available and in rather widespread use in many fields.
Reference is now made to FIGURE 6 where the hydraulic flow pattern is illustrated. Two hydraulic lifts 40 and 42 each consisting of a hydraulic cylinder, are connected to lines 44, 46 and 48. The line 44 extends from one port of the seat valve 50 This is a four-way valve having an off position, a position sending water through line 44 and to lift 40, and another position sending water through line 46 into lift 42 and a final position which would send water through line 48 to cylinder or lift 42. The lift 42 is a double acting cylinder whereas lift 40 is a single acting cylinder.
Double acting cylinder 42 is attached to a part of the seat frame 52 and attached to a bracket 60 that is carried by the cabinet. If desired, bracket 60 can be omitted with a direct connection made between the cylinder 42 and the cabinet. The cylinder is approximately parallel to the rails 56 and 58 of the track and when extended and retracted, moves the frame and frame supported seat 22 fore and aft of the cabinet.
The spray portion of the system is composed of a needle spray. This has a first conduit 64 closed at its outer end and connected in the water supply line at its inner end. A curved recess 65 is in the conduit and located below recess 38. This is approximately in the region of the neck of the occupant while the ends of the spray are at approximately shoulder level. Spray conduit 66 drops approximately vertically from the center charged. This pipe has ordinary fittings and a shower control valve 72 upstream of the spray head or spray. Another valve 74 is connected to pipe 70 and is arranged in parallel with valve 72. Spray head 78 at the end of flexible hose 80, is fed from valve 74- by having the flex ible hose 80 operatively connected with and controlled by valve 74. The purpose of the spray head is for showering of the occupant and/or the interior of the cabinet.
As indicated previously the cabinet can be drained through drain line 30. This can be a gravity flow drain. As an alternative or an option, a small pump 82 is mounted in a protective housing 84 (FIGURE and has a water inlet 86 whose intake end is in sump 28. Motor 88 drives the pump and has standard motor controls on the exterior of the cabinet. Selector valve 90 is in the drain line 30 and has three positions. One position is the oif position, another opens the drain line 30 and the third is to send Water under pump pressure through line 92 which is connected between valves 72 and 74 and to pipe 70. Therefore the water in the bottom of the cabinet can be recirculated for any reason.
In use, the occupant enters the cabinet and becomes seated on the contour chair or seat 22. After selecting the correct height of the seat and the correct fore and aft positions of the seat, the occupant is ready for bathing. hydro-therapy or any other treatment.
Of course, correct judgment for water temperatures are exercised by preselecting the correct temperature of water by the use of mixing valve 68. After hydro-therapy, showering, etc., the occupant is easily removed from the cabinet and the cabinet can be cleaned by relying wholly on the recirculation water or by relying on additional inlet Water. By using the recirculation water, detergent, disinfectant, etc. can be introduced into the cabinet through the spray system for sanitation and cleanliness.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
