concerning

A personal hygiene priority: March 20, 1970, the United Kingdom, No. 13 703/70.

The invention relates to an improved sanitary device for personal hygiene for use in incontinence of the Mrs.

The invention provides a device for the body hygiene of the incontinent woman, which is characterized is characterized by a first part intended for insertion into the vagina with a first opening for receiving secretions the uterus and a surface area defining this opening which is adapted to be in contact with the the tissue surrounding the uterus is a second

109841/1288

Part with a second opening for receiving from the Urethra derived fluid and a surrounding this opening Surface area which is designed so that he. is in contact with the tissue surrounding the urethra, with discharge lines connected to the openings and means for Regulating the flow of liquid in the discharge lines and setting subatmospheric pressure at the openings, so that the surface areas lie tightly against the tissue.

A one-way valve is preferably used as the means for regulating the flow of liquid, which consists of two flexible valves Plates or foils are made, which extend from the openings in the direction of the liquid flow. The one at the top Edges of the foils lying at the end of the stream are fastened relative to one another in such a way that the surfaces of the foils are opposite one another, When the valve is closed, the foil surfaces lie tightly against one another.

The wearer of the device according to the invention is kept dry, because this device lies against the carrier in a liquid-tight manner. Due to the fact that through the flow of liquid Maintain low atmospheric pressure from the carrier the device can be "simple in construction" and does not require an external suction mechanism.

For a better understanding of the invention, the following is a embodiment of the invention to be considered as an example

". Reference is made to the accompanying drawings Referred to '. - -

In these drawings Figure 1 is a perspective view of the first and second parts of the device; Figure 2 shows in perspective the part of the device that. the one-way valve includes;

FIG. 3 shows schematically in section the device located in situ on a carrier;

Figure 3A is a sectional view of part of the apparatus and
Figure 4 illustrates the principle of operation of the device.

The device 10 shown in Figure 1 comprises a vaginal part 11 and a vestibular part 12. The part 11 consists preferably made of an "inert plastic material, which does not cause an inflammatory tissue reaction and is designed to be inserted into the vagina and close to the carrier ^ rests. For this purpose, part 11 wing-like parts 13, a thickening 14 and projections or shoulders 15. An opening connected to a line 17 16, which is intended to receive the secretion from the uterus, is provided in the part 11.

The part 12 has an oval opening 18 which is delimited by a rim 19 and in connection with a line 20 stands. This opening 18 is intended to receive fluid from the urethra. Adjacent to the edge 19 and

- 4 109841/1288

Below this edge is a fine anti-edema mesh or net 21, which can consist of nylon "and covers the exit of the urethra when the device is attached to the wearer. A corresponding grid or Mesh may be provided over opening 16. The lines 17 and 20 are connected to a discharge line 22, the Receives secretion from part 11 and urine from part 12.

The parts 11, 12 can be of average size be, namely approximately 4 cm thick and approximately 7 cm long; however, they can as desired be smaller or larger.

The line 22 is formed by a hose of suitable length, for example a silicone hose, and is with a chamber 25 connected. The chamber 23 can be substantially cylindrical and about 8 cm long and can be made of consist of a suitable plastic material. The liquid flows out of the chamber through an opening 24 and the flow through opening 24 is controlled by a control device regulated in the form of a valve 25. Urine and secretion The urethra and uterus pass through the valve 25 and are collected in a suitable container 29 consisting of a Plastic bags or a bottle can be made and can be attached to the chamber 23 by suitable means. Of the The upper part of the container envelops the valve 25 without touching it or hindering its action.

- 5 -109841/12 88

As can be seen from Figure 3, the valve 25 includes opposing flexible plates or foils 26, the upper or upstream edges of which are attached to the edge regions of the wall of the opening 24 and the lower or downstream edges of which are freely movable. If the valve 25 is closed, the neighboring ones are located Inner surfaces of the plates against one another, as can be seen from FIG. These surfaces are processed in such a way that that they lie perfectly flat against one another and form a liquid-tight seal. The panels or Sheets can be about 3 cm long and made of a suitable plastic material.

Figure 3 shows schematically the device attached to a carrier. Inside is the back at 27, the uterus at 28, the vagina at 30, the bladder at 31, the urethra at 32 and the symphysis pubis at 33. Part 11 of the device is located in the vagina and the opening 16 is arranged to drain secretions from the uterus. The part 12 of the device is attached so that the opening and the protective screen or mesh 21 covers the urethra 32. The line 22 leads to the chamber 23, from which liquid flows through the valve 25 into the collecting vessel 29. As shown, vessel 29 contains some liquid 34 which has been withdrawn by the device.

With reference to FIG. 4, the

109841/1288

Principle of operation of the device according to the invention explained will. In Figure 4, the part 11 of the device has been omitted for the sake of clarity, since the functioning of the part 11 is based on the same principle as that of the illustrated part 12. For the sake of simplicity, the collection bag is also or - "container below valve 25 not shown.

The device is attached to the wearer and the line 22 is connected to the outlet opening 21. The administration 22 is closed with clamps, not shown, in order to prevent the escape of liquid. The evacuation chamber 23 is not connected to line 22 at this point and is 35 with a suitable antiseptic liquid filled up to the mark 36 (see Figure 2). Then the chamber 23 is connected to the line 22 and in a vertical position left hanging. The hose clamps are then released. Through the freely through the opening 24 of the chamber and through the valve 25 flowing liquid 35 creates a vacuum within the device. The foils or plates 26 pressed apart by the liquid against atmospheric pressure. After the pressure in the device is lowered to a predetermined value by the liquid flow a pressure equilibrium has been established, i.e. the reduced atmospheric pressure, for example 758 mm Hg, inside the device plus the fluid pressure of, for example, 2 mm Hg that inside the chamber

- 7 -109841/1288

■ remaining liquid equals the atmospheric pressure of 760 mm Hg acting on the valve. At this point the valve 25 closes and prevents another Flow of liquid from the chamber 23. The vacuum "created within the device" creates a liquid-tight Occlusion between the surfaces of the device 10 surrounding the openings 16, 18 and the tissues of the Wearer. The grid or net covering the openings 16, 18 prevents the tissue from being affected by this suction effect are injured, but allows the liquid to pass through.

The valve remains closed and prevents the escape of liquid from the chamber 23 (which favors the equilibrium a larger external pressure would interfere) until liquid flows through the device into the chamber 23. if If this occurs, the pressure equilibrium is disturbed by the pressure increase caused by the liquid in the chamber 23. This Equilibrium is immediately restored by adding an equal volume of fluid to that of the wearer separated liquid, flows through the valve 25, whereupon the valve closes again. The vacuum is thus at held at a substantially constant value, the tight seal on the surface between the device 10 and the tissues will not be eliminated and all volume of urine and / or secretion from the urethra or vagina will be constantly discharged in a liquid-tight manner.

The chamber 23 and the container 29 can be placed on the side of a bed or a wheelchair or placed on the floor will. In the case of outpatients, the collection system can be designed in such a way that it starts in the knee area attached to the lower limbs.
