Description

The technical field to which the utility model belongs:

The claimed utility model relates to medical technology, namely to sanitation and hygiene equipment, and is used to drain urine from women in various conditions that cannot be done in the natural position of the body. The device consists of a miniature urine collection funnel, which is connected with a flexible silicone tube to a device that includes a diaphragm pump, control boards, a variable resistor and a battery. A second silicone tube is used to connect the pump 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 then does not require the use of absorbent wipes.

Vehicle tier:

Many devices are known for female urination in extreme conditions.

Since the 1920s, several dozen urine-diverting funnels and tubes have been patented to enable women to urinate while standing - now they are sold under the brands Pibella, SheWee, Pstyle, Whiz Freedom, LadyP, Hopkins, and others. These tubes and funnels are made of solid plastic or silicone and allow the urine stream to be directed 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 setting or in case of urinary incontinence in patients in medical practice, urinals are used - reservoirs for collecting and taking urine for analysis. Distinguish between bedside urine bags ("duck" with a neck like "willow leaf", "medical vessel"), wearable leg urine bags and gel urine bags like diapers. The former are intended for patients arriving in a supine state, but able to lift the pelvis to use the drainage container [1]. In the second case, wearable urine bags are combined with urological catheters - a tube that is inserted into the bladder through the urethra to drain urine from the bladder. This method of urinary diversion is used in sedentary patients or in case of urinary incontinence. The duration of this method is usually limited to a few days, or it is associated with rather laborious tactics of replacing the catheter [2]. The use of gel bags is non-invasive and may not require active movement of the patient's pelvis, however, the amount of fluid absorbed is usually limited to 750 ml, which leads to frequent and energy-intensive replacement.

The closest device to the claimed utility model can be called the model of VN Nikiforov, patented in 2014 [3]. The solution proposed by Nikiforov is a composite device with a guiding chamber with a branch pipe, attached to the pelvic region of a woman with the help of special underpants, tubes leading from her, and a container for collecting urine, attached to the leg. The similarity of the claimed model and the analogue of V.N. Nikiforov is to use a guiding chamber with a branch pipe and an external structure for collecting biological fluid with an antireflux valve.

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

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

2. urination without active movement of the pelvis in recumbent 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).

Disclosure of the essence of a utility model

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

1. None of the known designs of funnels and necks of urine bags does not use the area that exerts lateral pressure on the labia minora in the region of the clitoris. This innovation of the claimed utility model allows directing the external opening of the urethra anteriorly, along the cavity of the funnel bowl, thereby directing the urine stream directly to the outlet opening of the funnel pipe. This not only prevents splashing, but also eliminates the need for subsequent use of absorbent wipes.

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

3. None of the known solutions involves active mechanical removal of liquid biological material (urine). The inventive solution allows urine to be diverted through a tube, which is also in an upright position.

4. The use of a diaphragm pump solves the problem of "idling", allowing without inconvenience to keep the device turned on in the absence of urination.

5. The proposed method of collecting urine allows researchers and doctors to make a record of the volume and further clinical analysis of liquid biological material in vitro, since the collected fluid 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 for women.

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

от длины малых половых губ.The urine diverting funnels of the claimed model will be presented in various sizes, differing in the long bowl of the funnel, its depth and the height of the transverse protrusion. In general, the volume of the urinary funnel corresponds to the volume of a woman's labia minora (labium minor pudenda), and its length is

from the length of the labia minora.

The material for the bowl is polypropylene or another hard plastic with similar properties.

The dimensions of the bowl of the funnel are chosen so that it tightly encloses the woman's labia minora (labium minor pudenda) on the sides and fits snugly with the posterior end to the vestibule of the vagina (vestibulum vaginae). The front end of the funnel with the outlet has a semicircular projection facing perpendicular to the edges of the bowl. During use of the funnel, this protrusion exerts moderate pressure on the labia minora perpendicularly, just below the glans clitoridis, directing the external opening of the urethra (ostium urethrae externum) anteriorly, towards the urinary duct (see Fig. 4).

The urine diversion pipe has a small socket at the end and is connected in a collapsible way with 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 configuration of the funnel allows you to use both short (about 13 cm) and long (about 40-50 cm) silicone tubes with it. In the first case, this allows the woman to urinate while standing without taking off her underwear or using absorbent wipes. In the second case, a long silicone tube is connected to the inlet of the membrane pump, which, using the hardware (a control board with a microcontroller, a motor control module, a variable resistor, a step-up board, a battery and a power button), removes the liquid biological material (urine) through the outlet a hole through the second silicone tube (a short tube from the first use case can be used) into a collection container with a volume of 0.3-0.5 liters, equipped with a check valve (see Fig. 2).

The diaphragm pump motor operates at a voltage of 5-8 V, the voltage changes due to the rotation of the variable resistor knob. The suction rate is approximately 1.5-3 l / min. Changing the rate of suction allows you to apply the claimed utility model in a standing position, sitting on a flat surface, lying or lying on your side, avoiding leakage.

The body of the hardware part is dismountably fastened to the side of the upper part of the urine collection container and has hooks-carabiners for fixing the body of the hardware part with the collection container on clothes or medical structures on which a person is placed - this solution allows, after turning on the pump, to use only one hand for holding the funnel in the proper position (see Fig. 2).

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

Implementation of the utility model

The implementation of the utility model provides the functional unity of two improved structural elements: 1) an elongated urine diversion funnel with a transverse protrusion and 2) a hardware part with a membrane pump.

The idea of a hard plastic urine-diverting funnel resting directly on the labium minor pudenda was implemented in the form of a tube by the brands Pibella and SheeWee. The hardness of the plastic and the limited plane of the girth of the external genital organs of the woman allows for more accurate removal of liquid biological material, but this result requires training, which ultimately ensures comfortable urination in an exclusively standing position.

The difference between the funnel of the claimed model consists in a transverse rounded protruding area running perpendicularly or with a slight slope of 1-3 degrees to the edges of the bowl, which is slightly pressed into the labia minora, just below the head of the clitoris (glans clitoridis), directing the external opening of the urethra (ostium urethrae externum) anteriorly, towards the urinary branch pipe. 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 there is no leakage, as it contributes to an additional specified direction of urine flow.

The second functional element of the design is the hardware part with the membrane pump. Diaphragm pumps with similar characteristics are used in aquaristics and in dispensers, for pumping water or machine oil and other liquid (including chemically aggressive) media. Miniature diaphragm pumps are distinguished by their small size, ease of use and the ability to work with liquids of different densities and different chemical compositions.

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

The body of the hardware part has fastenings for a container for collecting liquid biological material (urine) with a volume of 0.5 liters and hooks-carabiners for possible attachment to clothes or to structures of wheelchairs or beds. The container for collecting urine is equipped with a check valve to prevent spilling of liquid when the device is horizontal. It is important to note that in the connected form, the housing with the hardware is located under the upper part of the collection container, which in the horizontal position of the device gives its additional angle of inclination, at which liquid accumulates in the lower part of the container.

When used individually as a sterilization process, it is allowed to rinse the claimed utility model with running water, or with a cold disinfectant solution and then running water, when it is switched on.

In a hospital setting, it is allowed to replace the urine diverting funnel and long tube after changing the user of the device, or sterilize the device using 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 a complete absence of leaks (no more than 1 ml per one act of urination), which makes it possible to use this method without the use of absorbent wipes. The tests were carried out in a standing position, the funnel was pressed against the labia minora with the index and middle fingers of one hand (see Fig. 2).

In the second case, the tests were carried out in the supine position; lying on its side with the upper leg bent and raised; while sitting on a flat surface (chair). The funnel was also pressed against the labia minora with the index and middle fingers of one hand. In all cases, during the first 2-3 tests, urination was difficult due to psychological barriers. Nevertheless, the method of urination when using the claimed model showed efficiency and absence of leaks (no more than 2 ml per one act of urination), which later (after 3-4 tests) led to a 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.) make it possible to talk about the effectiveness and practicality of the proposed solution ...
