Female chair urinal

A urinal device for use by female persons not having the use of their legs while seated in a chair or wheelchair. The urinal device has a pie-slice shaped shallow pan with a swollen, bulbous cross-section lip completely around the periphery thereof and a perforated splash plate. A handle is affixed to the pan opposite the narrow end of the pan so that the impaired person may insert the pan beneath her body without lifting her body or legs from the chair seat. The pan is continuously drained during use by means of a drainage hose connected to a urine receiving container.

BACKGROUND OF THE INVENTION 
1. Field 
The field of the invention is urinals for handicapped females confined to 
chairs or wheelchairs for extended periods, and more particularly such 
devices which may be used by chair ridden person without aid from any 
nurse or other attendant. 
2. Prior Art 
Many patients are rendered chair or wheelchair ridden because of a disease 
robbing them of the use of their legs, while leaving their arms strong and 
free. Often, such patients are quite self-sufficient, using the mobility 
provided by the wheelchair to fulfill many of their needs without 
assistance of an attendant. However, such patients often need assistance 
to be moved from the wheelchair onto a commode for urinating. Prior art 
bed pans are typically too bulky for such patients to lift themselves onto 
with their arms while placing the bed pan for urination. Even if it is 
possible to properly place the pan, a further gymnastic effort is required 
to remove it after use. Nor can the pan be placed aside further than arm's 
length without assistance. This distance is not far enough to prevent an 
open bed pan from emitting detectable unpleasant odors, although the user 
may be able to remove herself from the vicinity of the odorous pan by use 
of the wheelchair. 
A definite need therefore exists for a urinal for use by chair-ridden 
female persons who have lost the use of their legs for mobility, such 
needed devices being capable of easy placement beneath the patient for 
collection of the urine into substantially odor free storage until 
assistance is again available. The needed device thus must permit extended 
periods of unattended time. 
BRIEF SUMMARY OF THE INVENTION 
With the foregoing in mind, the present invention eliminates or 
substantially alleviates the shortcomings in prior art urination devices 
for chair ridden female persons, by providing a receptacle pan for the 
urine which may be easily placed in proper position by the 
leg-use-impaired female in chair or wheelchair. 
The inventive female urinal comprises a shallow urine receiving pan shaped 
and sized to be manually thrust into position under a female person 
without raising her body. That is, the inventive pan is quite thin 
vertically, so that it may be easily forced beneath the patient's 
posterior, taking advantage of the compressibility of the bedding and also 
to a large extent of the buttocks and thighs of the user. The pan is 
rounded completely around the periphery thereof and the device includes, 
an elongate forwardly directed handle affixed thereto to aid in thrusting 
the pan into a urine receiving position, without lifting her body from the 
seat of the chair, further aided by tapering, buttock spreading shape. The 
urine receptacle is pie-slice shaped being tapered toward the rear of the 
user and is somewhat broader toward her front, so that the pan may be 
comfortably placed and the urine efficiently collected although the pan is 
very small compared to the state of the art bed pans. 
To prevent overflow or spillage from the shallow pan, a flexible tube 
extends to a collection bottle, which may be sized to accept accumulated 
urine from several excretions. Preferably, the pan includes a perforated 
splash plate thereacross at an intermediate level. 
It is therefore the object of the invention to provide a urinal which may 
be used by leg impaired chair or wheelchair-ridden female persons without 
the aid of a nurse or other attendant.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENT 
The inventive female chair urinal device 10 includes a shallow, upwardly 
opening urine collection pan 11 an attached elongate handle 14, and a 
urine receiving and disposal bottle 13. Handle 14 is angled upwardly from 
front rim 15 of pan 11 and carries a conventional hand grip 16. (FIG. 1) 
To use urinal device 10, pan 11 is inserted by the user from her front, 
rearwardly beneath her buttocks, employing grip 16. Pan 11 is very 
shallow, and carries a smoothly rounded, swollen bulbous cross-section lip 
continuous 17 all around its periphery. (FIGS. 2-4) Because of its size 
and shape, pan 11 may be inserted into a urine receiving position without 
any lifting of the user's legs or body from the chair seat. The tapered, 
rounded pie-slice shape of pan 11 when viewed from above is narrow at the 
rear or apex end and broad at the opposite or front end. (FIG. 2) 
As indicated above, the collection pan 11 must be rounded on all surfaces 
that would come into contact with the skin of the patient during 
placement, and also on all surfaces that may during the placement for use 
contact the bedding or cushioning upon which the user sits. Contained 
within pan 11 is a perforated splash plate 18 through which the urine is 
passed into a lower reservoir 19. 
Preferably, the pan 11 is made of corrosion resistant metal such as 
stainless steel, and comprises an upper half 20 and a lower half 21 which 
are shaped separately and later secured along a joint line 22 by welding, 
silver soldering, or other means, not shown, suitable for permanently 
joining the particular material selected. (FIGS. 3 & 4) The splash plate 
18 is preferably formed as part of upper half 20 of pan 11. This 
eliminates most hard to clean recesses and niches which would be created 
if a separate screen were utilized, fastened to a molded edge portion, not 
shown in this embodiment, provided on upper shell 20. 
Because the pan is very shallow and also very narrow to facilitate its 
placement for use, its urine-holding capacity is correspondingly small, so 
that drain provisions may be needed to prevent overflow during use. 
Through a hole 23 in bottom half shell 21 is disposed a small, short steel 
tubular connection tube 24 which is secured thereto such as by welding, 
silver soldering, or other suitable means, to which is connected for a 
surgical tubing drain hose 25 communicating with a urine collection bottle 
13. Connection tube 24 is directed forwardly and down at a small angle, so 
as to not extend greatly below the flat bottom of pan 11. This reduces 
bending pressure on connection tube 24 and facilitates placement of pan 11 
for use. 
The inventive apparatus may be embodied in other specific forms without 
departing from the spirit or essential characteristics thereof. The 
present apparatus is therefore to be considered illustrative and not 
restrictive, the scope of the invention being indicated by the appended 
claims rather than by the foregoing description and all equivalencies of 
the claims are therefore intended to be embraced therein.
