Description

The technical field to which the utility model relates:

The inventive utility model relates to medical equipment, namely to the equipment of sanitation and hygiene, and is used to divert urine in women in various conditions that do not represent the opportunity to do this with the natural position of the body. The device consists of a miniature funnel-urinal, which is connected with a flexible silicone tube to the apparatus, which includes a membrane pump, control boards, a variable resistor and a battery. Using a second silicone tube, the pump is connected to a container for storing and transporting urine. The technical result of the claimed utility model is to facilitate the independent collection of liquid biological material by a woman, regardless of the position of her body in space - lying, sitting on a flat surface, standing. The inventive device allows you to urinate without taking off your clothes, and after that does not require the use of absorbent wipes.

The prior art:

There are many devices for female urination in extreme conditions.

Since the 1920s, several dozen urine funnels and tubes have been patented, allowing women to urinate in a standing position - they are now available under the brands Pibella, SheWee, Pstyle, Whiz Freedom, LadyP, Hopkins, etc. These tubes and funnels are made of solid plastic or silicone and allow you to direct the stream of urine anteriorly. However, a common problem with this solution is the lack of tightness when in contact with the body, which leads to leaks during use.

In a hospital or in case of urinary incontinence in patients in medical practice, urinals are used - reservoirs for collecting and taking urine for analysis. There are bedside urinals (“duck” with a neck like “willow leaf”, “medical vessel”), wearable foot urinals and gel urinals like diapers. The former are intended for patients arriving while lying down, but able to raise their pelvis in order to use the capacity of the urinal [1]. In the second case, wearable urinals are combined with urological catheters - a tube that is inserted into the bladder through the urethra with the aim of outflow of urine from the bladder. This method of urination is used in sedentary patients or in case of urinary incontinence. The duration of application of this method is usually limited to several days, or is associated with rather laborious tactics of replacing a catheter [2]. The use of gel urinals is non-invasive and may not require active movement of the patient's pelvis, however, the amount of absorbed fluid is usually limited to 750 ml, which leads to their frequent and energy-intensive replacement.

The device closest to the claimed utility model can be called the V. N. Nikiforov model, patented in 2014 [3]. The solution proposed by Nikiforov is a composite device with a guide chamber with a nozzle attached to the pelvic area of a woman using special pants, tubes leading from her, and a urine collection container attached to the leg. The similarity of the claimed model and analogue V.N. Nikiforova consists in using a guide chamber with a nozzle and a remote structure for collecting biological fluid with an antireflux valve.

However, in all of the above solutions there are limitations that are solved in the claimed utility model. In particular, the claimed model solves the problems:

1. leakage (which occurs when using silicone funnels or funnels leaning against the groin or labia loosely);

2. urination without active movement of the pelvis in bedridden and seated patients;

3. there is no invasiveness of the urological catheter (which means that this method is more gentle and does not lead to possible infectious complications and damage to the urethra).

Utility Model Disclosure

The technical problem is solved with the help of several innovations of the claimed utility model:

1. None of the known constructions of the funnels and necks of the urinals uses an area that exerts lateral pressure on the labia minora in the area of the clitoris. This innovation of the claimed utility model allows you to direct the outer opening of the urethra anteriorly, along the cavity of the funnel, thereby directing a stream of urine directly to the outlet of the funnel. This not only prevents splashing, but also eliminates the need for subsequent use of absorbent wipes.

2. The small size of the claimed funnel design allows you to use it in conditions that do not imply the ability to remove items of underwear or to change the position of the body - lying, sitting on a flat surface, standing (for bedridden patients, women in wheelchairs, women leading an active lifestyle and other).

3. None of the known solutions involves active mechanical abduction of liquid biological material (urine). The claimed solution allows the diversion of urine through a tube, which is also in a vertical position.

4. The use of a diaphragm pump solves the problem of “idling”, allowing the apparatus to be turned on without urination without causing inconvenience.

5. The proposed method for collecting urine allows researchers and doctors to record volume and further clinical analysis of liquid biological material in vitro, since the collected liquid does not include vaginal discharge.

6. Due to the fact that the technology is non-invasive, it allows multiple use without possible complications and constant discomfort of a woman.

The urinary funnel of the claimed model is an elongated, deepened bowl protruding perpendicularly or with a slight slope of 1-3 degrees to the cavity of the bowl with a rounded part and a pipe under it, whose opening goes in the same direction with the bottom of the bowl of the urine funnel, - at the front end, and tapering up and sides with the opposite rear end (see Fig. 1).

от длины малых половых губ.The urinary funnels of the claimed model will be presented in a different size range, differing in the length of the funnel bowl, its depth and the height of the transverse protrusion. In general, the volume of the urinary funnel corresponds to the volume of the labia minor pudenda of the woman's labia minora, and its length is

from the length of the labia minora.

As the material for the bowl, polypropylene or other hard plastic with similar properties is used.

The dimensions of the funnel bowl were chosen so that it tightly covered the labia minor pudenda of the woman's labia minora on the sides and the rear end and was tightly attached to the vestibule (vestibulum vaginae). The front end of the funnel with the outlet pipe has a semicircular protrusion facing perpendicular to the edges of the bowl. During the use of the funnel, this protrusion exerts moderate pressure on the labia minora perpendicularly, just below the clitoris head (glans clitoridis), directing the external opening of the urethra (ostium urethrae externum) anteriorly, towards the urinary tube (see Fig. 4).

The urine outlet has a small socket at the end and is connected in a collapsible manner to a silicone tube, the wall thickness of which is 2 mm, the inner diameter is not more than 6 mm and not less than 4 mm.

The funnel configuration allows using both a short (about 13 cm) and a long (about 40-50 cm) silicone tube with it. In the first case, this allows the woman to urinate in a standing position, without removing her underwear and without using absorbent wipes. In the second case, a long silicone tube is connected to the inlet of the diaphragm pump, which, using the hardware (control board with a microcontroller, a motor control module, a variable resistor, a boost board, a battery, and a power button), discharges liquid biological material (urine) through the outlet a hole in the second silicone tube (a short tube from the first use case may be used) into a collection vessel of 0.3-0.5 L capacity, equipped with a check valve (see Fig. 2).

The membrane pump motor operates at a voltage of 5-8 V, the voltage changes due to the rotation of the handle of a variable resistor. The suction rate is approximately 1.5-3 L / min. Changing the suction rate allows you to use the claimed utility model in a standing position, sitting on a flat surface, lying or lying on its side, preventing leakage.

The hardware case is collapsibly fastened to the side with the upper part of the urine collection container and has hooks to fix the hardware case with the collection container on clothes or medical structures that a person is placed on - this solution allows you to use only one hand to turn on the pump holding the funnel in the proper position (see Fig. 2).

The case of the hardware is also equipped with a compartment for storing a urine funnel and connecting it to the hardware of a long silicone tube.

Utility Model Implementation

The implementation of the utility model gives the functional unity of two improved structural elements: 1) an elongated urinary funnel with a transverse protrusion and 2) the hardware with a diaphragm pump.

The idea of a hard plastic urine funnel, leaning directly on the labia minor pudenda, was realized in the form of a tube by the brands Pibella and SheeWee. The hardness of the plastic and the limited plane of girth of the woman’s external genital organs allows for more accurate removal of biological liquid material, however, for this result, training is required, which ultimately ensures comfortable urination in an exclusively standing position.

The difference between the funnel of the claimed model lies in the transverse rounded protruding region, going perpendicularly or with a slight slope of 1-3 degrees to the edges of the cup, which is slightly pressed into the labia minora, just below the clitoris head (glans clitoridis), directing the external opening of the urethra (ostium urethrae externum) anteriorly, towards the urinary branch. The shape of the funnel bowl allows you to correctly position the funnel on the labia minora without long training, and a special protrusion ensures that it does not leak, as it contributes to the additionally specified direction of urine flow.

The second functional structural element is the hardware with a diaphragm pump. Diaphragm pumps with similar characteristics are used in aquariums and dispensers, for pumping water or engine oil and other liquid (including chemically aggressive) media. Miniature diaphragm pumps are distinguished by their small size, ease of operation and the ability to work with liquids of different densities and different chemical composition.

In the claimed utility model, a diaphragm pump with a voltage in the range of 5-8 V and a suction speed of 1.5-3 l / min is controlled by the motor control module and is regulated by turning the handle of a variable resistor connected to the control board with a microprocessor and is powered by a battery with a capacity of 2200 mAh and a voltage of 3.7 A, equipped with a boost board and micro-USB module. Such a design solution has high autonomy and safety, low weight (no more than 250 grams) and size (10 × 8 cm).

The body of the hardware has fastenings for a container for collecting liquid biological material (urine) of 0.5 l and hooks-carabiners for possible attachment to clothes or to designs of wheelchairs or beds. The urine collection tank is equipped with a check valve that does not allow spillage of liquid when the device is horizontal. It is important to note that in a connected form, the case with the hardware is located under the upper part of the collection tank, which in the horizontal position of the device gives it an additional angle of inclination, at which the liquid accumulates in the lower part of the tank.

For individual use as a sterilization process, it is allowed to flush the claimed utility model with running water, or with a cold disinfectant solution and then with running water, when turned on.

In a hospital environment, it is allowed to replace the urine funnel and long tube after changing the user of the device, or sterilize the device with cold disinfectant solutions, followed by rinsing with running water.

Testing of the claimed model was carried out with two research methods - without connecting the hardware (passively, using a short silicone tube) and with connecting the hardware.

In the first case, the tests showed a high degree of comfort of use and the complete absence of leaks (not more than 1 ml per act of urination), which allows you to use this method without the use of absorbent wipes. The tests were carried out in a standing position, the funnel was pressed to the labia minora using the index and middle fingers of one hand (see Fig. 2).

In the second case, tests were carried out in supine position; lying on its side with a bent and raised upper lying leg; in a sitting position on a flat surface (chair). The funnel was also pressed against the labia minora using the index and middle fingers of one hand. In all cases, in the first 2-3 tests, urination was difficult due to psychological barriers. Nevertheless, the method of urination when using the inventive model showed the effectiveness and absence of leaks (no more than 2 ml per act of urination), which later (after 3-4 tests) led to the weakening of previous stereotypes and made urination psychologically comfortable even in unusual conditions . This result shows that the use of the claimed model requires a habit, but the opportunities that it provides for some groups of women (disabled people with paralyzed lower limbs, bedridden patients, women in cars standing in traffic jams, etc.) allow us to talk about the effectiveness and practicality of the proposed solution .
