DESCRIPTION:
BRIEF SUMMARY
The invention relates to a permanent urine-collecting receptacle for women.
European patent document No. A-148 047 and European patent document No. A-287 441 disclose equipment intended for the incontinent and making it possible to detect and pump the urine collected in the urinary tract in order to store it in a flexible bag, which is generally held by a belt.
This equipment is satisfactory but, in some cases, collection of the urine is less than perfect, especially when the subject adopts certain positions, in particular a lying position. Furthermore, in cases of both urinary and fecal incontinence, the operation of this equipment is found to be upset by the discharge of feces.
Female incontinence is more widespread than male incontinence and improved collecting receptacles for women have already been proposed.
Thus urine drainage devices are known which are worn permanently by the subject. U.S. Pat. Document No. A-4,583,983 shows such a drainage device, which has a plate and a beveled oblong duct for cooperating with the urethra at the urinary meatus in order to collect the urine, which is then discharged directly under gravity into a flexible bag. Although this drainage device can prove satisfactory in the simplest cases, i.e. when the female organs are of a regular shape and when the subject is in a vertical position, it is clear that it is not satisfactory when the subject is in a lying position and/or when the anatomy of the urinary region is disturbed, for example following the prolapse of an organ.
Temporary collecting receptacles of the urinal kind are also known. For example, European patent document No. A-185 517 shows such a urinal which is intended to be used exclusively on a temporary basis by a subject who is lying down. This is totally different from the permanent collecting receptacles to which the present invention relates.
The object of the invention is to prepare a permanent receptacle which is devoid of the above-mentioned disadvantages and which is particularly suitable for use with the detection and pumping equipment mentioned at the beginning of this specification.
The invention achieves its object by proposing a receptacle of the plate and duct type in which the plate has a raised lip shaped so as to surround the female organs, the said duct being located in the interior zone of the said lip and being surrounded by a channel and, on one side only, by a dish; the duct and the channel communicate with a collecting chamber adjoining the plate.
By virtue of a degree of flexibility, the raised lip ensures perfect leaktightness between the collection zone and the outside, in either direction. On the one hand, irrespective of the position of the female subject, the urine passed is collected either by the duct in the most normal case, or by the dish and the channel in other cases, with no leakage to the outside. On the other hand, the rear part of the lip forms a barrier to the discharge of any feces which might disturb the operation of the device.
The collecting chamber has discharge means which can be a gravity flow orifice connected, for example, to a receiving bag situated lower down; more advantageously, these means are associated with a detection and pumping system, for example the one in the patents cited at the beginning of this specification.
In that case, the discharge means are advantageously provided in the top part of the chamber.
The receptacle is preferably obtained by flow casting from a semi-flexible material such as a natural latex, whose flexibility makes it possible to avoid harshness on the female organs and to fit their contour more easily.
Further characteristics and advantages of the invention will become apparent from the following description of a preferred embodiment. Reference is made to the attached drawings, in which:
FIG. 1 is a 3/4 perspective of the receptacle of the invention;
FIG. 2 is a top view of the same receptacle; and
FIG. 3 is a side view thereof with a partial cutaway.
The receptacle 1 is a semi-flexible semi-rigid article advantageously made of
