Description

Technical Field

[0001] The invention belongs to the field of medical equipment, and in particular relates to a children's urine collection device. Background Art

[0002] Clinically, the thoughts, thinking and actions of young children are not yet mature. From the theory of children's psychological growth, it is known that children aged 0-2 years old cannot completely control their urination and defecation. Therefore, it is difficult to collect urine samples from infants and young children aged 0-2 years old on a regular basis. Especially in the pediatric intensive care unit, there are children of various ages with serious diseases, especially those with abnormal mental systems, such as children in a coma. It is also difficult to collect urine samples from them on a regular basis. The urine collection device used in clinical practice is generally a urine cup. During the urine collection process, the examinee will often splash urine into his hands because the urine cup has a small collection port and is unstable. This is very unhygienic. In addition, the sample is prone to secondary contamination in the process of pouring the urine cup into the test tube, which affects the test results. The current method of collecting urine samples in hospital laboratories is to first discharge urine into a urine cup, and then transfer it from the urine cup to a urine collection tube for testing. This method is not only unhygienic, but the secondary transfer will contaminate the urine sample, which may affect the final laboratory test value, leading to adverse consequences such as false positives and false critical values. The urine sample in the cup is often spilled or accidentally knocked over, polluting the environment. Therefore, it is extremely necessary to design a device that can collect samples in a timely manner and ensure that the sample is not contaminated by human beings during the collection process. When collecting urine, the early urine is easily affected by the cleanliness of the surface of external organs, so the middle urine is usually selected for testing.

[0003] Chinese patent publication number "CN117083036A" and the name of the patent are "Urine Collection Device". The patent discloses a children's urine collection device. The device adopts a complex structure to achieve the function of preventing urine leakage, but the effect is not very obvious for children, and it does not solve the problem of early urine abandonment. Summary of the invention

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to provide a children's urine collection device, which can avoid contamination during the transfer process and is easy and hygienic to use.

[0005] The technical solution of the present invention is achieved as follows: a children's urine collection device includes a collecting bucket, a control valve, a catheter, a first compression bag and a second compression bag. The collecting bucket is connected to the control valve through a catheter, and the control valve is connected to the first compression bag or the second compression bag through a catheter. The collecting bucket matches the shape near the urethral opening and is tightly installed next to the urethral opening using atmospheric pressure or elastic force. The control valve is a three-way control valve that can control the connection and disconnection between the collecting bucket and the first compression bag or the second compression bag. The first compression bag or the second compression bag is provided with an upper support plate, a lower support plate and a bag body, the upper support plate and the lower support plate are respectively located at both ends of the bag body, the bag body is made of flexible material, and the upper support plate and the lower support plate have a certain rigidity so that when the upper support plate moves in a divergent direction relative to the lower support plate, the bag body can be stretched to expand the volume of the bag body.

[0006] The beneficial effect of such a design is that hanging a weight or applying a pulling force under the first compression bag or the second compression bag can make the bag body tend to expand in volume, so that a negative pressure can be formed in the bag body. The bag body is connected to the collecting bucket through a catheter, so a negative pressure can be generated in the collecting bucket. The collecting bucket can avoid or reduce urine leakage at about atmospheric pressure, making the urine collecting device cleaner and more sanitary. The first compression bag and the second compression bag can be provided to discard the urine in the front and rear sections, so that more accurate data can be obtained. The urine in the front and rear sections is generally more susceptible to contamination or has a higher concentration. In addition, the penis of children is not developed, so the design for ordinary adults is difficult to use on children. However, the technical solution of the present application is suitable for all ages and has a wider range of use, but different sizes and models need to be set.

[0007] Furthermore, the collecting bucket is fixed on the trouser body, and the trouser body is made of water-absorbing material, so as to avoid local moisture caused by urine leakage and make the user more comfortable.

[0008] Furthermore, the first compression bag or the second compression bag is provided with a transparent bag body, and a pH test paper is provided in the bag body, so that it is convenient to judge the acidity and alkalinity of urine.

[0009] Furthermore, the control valve includes a valve body and a valve core, the valve body is provided with at least one inlet and two outlets, the valve body is provided with a valve hole in a direction perpendicular to the inlet and the outlet, the valve hole is provided with a valve core, the valve core is provided with a first channel and a second channel, and when the valve core moves axially along the valve hole, the connection state between the inlet and the two outlets can be changed, thereby facilitating the control of the flow direction of urine.

[0010] Furthermore, the second compression bag is provided with an exhaust port, and a rubber diaphragm is provided on the outside of the exhaust port. When the air pressure in the bag body is greater than the atmospheric pressure, the rubber diaphragm can be partially separated from the exhaust port to achieve exhaust. A breathable and waterproof membrane is provided on the inside of the exhaust port so that gas can pass through the breathable and waterproof membrane but liquid cannot pass through the breathable and waterproof membrane, thereby facilitating the discharge of gas in the compression bag.

[0011] Furthermore, both the upper support plate and the lower support plate are provided with hanging rings, which facilitates hanging.

[0012] Furthermore, the lower support plate is provided with an iron sheet, and a magnet is provided under the lower support plate which can be adsorbed under the iron sheet, so that the magnet can be used to provide negative pressure in the compression bag, and it is convenient to disassemble after multiple uses.

[0013] Furthermore, the bag body is provided with a plurality of circular rings, and the plurality of circular rings are arranged in parallel. This has a simple structure and can provide a relatively large negative pressure under the action of a heavy object or a pulling force.

[0014] Furthermore, a plurality of annular plates are provided outside the bag body, which have certain elasticity and strength and can be changed from a planar structure to a conical structure. In this way, the bag body can be gradually expanded from a very small volume to a larger volume, which can be achieved by hanging heavy objects or providing pulling force under the bag body.

[0015] Furthermore, the upper support plate is provided with a urination valve, which makes it convenient to take out urine for testing. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] As required, detailed embodiments of the present invention are disclosed herein, but it should be understood that the disclosed embodiments are merely exemplary of the present invention, and the present invention may be implemented in different and alternative forms. The accompanying drawings may not be drawn to scale, and certain features may be exaggerated or reduced to show the details of specific components. Therefore, the specific structural and functional details disclosed herein should not be understood as having a limiting meaning, but only as a representative basis to teach those skilled in the art to adopt the present invention differently. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a child urine collection device comprises a collecting bucket 1, a control valve 2, a urinary catheter 3, a first compression bag 4 and a second compression bag 5. The collecting bucket 1 is connected to the control valve 2 through the urinary catheter 3, and the control valve 2 is connected to the first compression bag 4 or the second compression bag 5 through the urinary catheter 3. The collecting bucket 1 matches the shape near the urethral opening and is tightly installed beside the urethral opening by using atmospheric pressure or elastic force. The control valve 2 is a three-way control valve 2 that can control the connection and disconnection of the collecting bucket 1 and the first compression bag 4 or the second compression bag 5. The first compression bag 4 or the second compression bag 5 is provided with an upper support plate 7, a lower support plate 8 and a bag body 9. The upper support plate 7 and the lower support plate 8 are respectively located at two ends of the bag body 9. The bag body 9 is made of flexible material. The upper support plate 7 and the lower support plate 8 have a certain rigidity so that when the upper support plate 7 moves in a divergent direction relative to the lower support plate 8, the bag body 9 can be stretched to expand the volume of the bag body 9. The collecting bucket 1 can be designed with reference to the existing technology. The same design is used for boys and girls. The collecting bucket 1 is designed with silicone, and the opening position is set with a plane with a certain curvature, which can match the shape of the skin near the vulva or penis. In this way, after squeezing out the internal air, the collecting bucket 1 can be directly pressed near the vulva or penis by atmospheric pressure. You can also refer to the existing technology such as the technical solution disclosed in "CN117083036A", so that it can also be used on adults.

[0025] like Figure 1 As shown, the collecting bucket 1 is fixed on the trouser body 10, and the trouser body 10 is made of absorbent material.

[0026] like Figure 1 As shown, the first compression bag 4 or the second compression bag 5 is provided with a transparent bag body 9, and a PH test paper is provided in the bag body 9. A urine detection circuit is provided in the first compression bag 4. When there is urine in the first compression bag 4, the circuit is turned on and an alarm is sounded, so that it is convenient to know when to start urinating, and the control valve 2 is turned to the position of the second compression bag 5 to start collecting urine required for inspection.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, the control valve 2 includes a valve body 20 and a valve core 21. The valve body 20 is provided with at least one inlet 22 and two outlets 23. The valve body 20 is provided with a valve hole in a direction perpendicular to the inlet 22 and the outlet 23. The valve hole is provided with a valve core 21. The valve core 21 is provided with a first channel 24 and a second channel 25. When the valve core 21 moves along the axial direction of the valve hole, the connection state between the inlet 22 and the two outlets 23 can be changed. Of course, it is also possible to directly set a channel to achieve control, but this is likely to cause the control valve 2 to be disconnected when it is in a certain position, and urine is prone to leakage. Setting up a dual channel can ensure that at least one channel is in a connected state, and negative pressure can be used to avoid leakage. The outlet 23 is provided with a one-way flow diaphragm 26 to prevent backflow.

[0028] like Figure 2 , Figure 5 and Figure 6 As shown, the second compression bag 5 is provided with an exhaust port 11, and a rubber diaphragm 12 is provided on the outside of the exhaust port 11. When the air pressure in the bag body 9 is greater than the atmospheric pressure, the rubber diaphragm 12 can be partially separated from the exhaust port 11 to achieve exhaust. A breathable waterproof membrane 13 is provided on the inside of the exhaust port 11 so that gas can pass through the breathable waterproof membrane 13 but liquid cannot pass through the breathable waterproof membrane 13. Figure 6 When the rubber diaphragm 12 is in the exhaust state, it partially detaches from the upper support plate 7 of the compression bag. Figure 5 In the non-exhaust state, the rubber diaphragm 12 is tightly attached to the support plate 7 on the compression bag.

[0029] like Figure 1 As shown, both the upper support plate 7 and the lower support plate 8 are provided with hanging rings 6, which can be hung when in use.

[0030] like Figure 1 and Figure 2 As shown, the lower support plate 8 is provided with an iron sheet, and a magnet 14 is provided below the lower support plate 8 which can be adsorbed under the iron sheet, so that a certain negative pressure can be generated in the bag body 9 by utilizing gravity.

[0031] like Figure 1 and Figure 2 As shown, the upper support plate 7 is provided with a urination valve 17, which makes it convenient to take out urine for testing.

[0032] Embodiment 1:

[0033] like Figure 1 and Figure 2 As shown, the bag body 9 is provided with a plurality of annular plates 16, which have certain elasticity and strength and can be changed from a plane structure to a conical structure, so that they have good deformation ability and can generate a certain negative pressure. The bag body 9 is made of plastic film. If there is no annular plate 16, the negative pressure generated is small, and it is difficult to meet the need to prevent urine leakage.

[0034] Embodiment 2:

[0035] like Figure 1 and Figure 7 As shown, the bag body 9 is provided with a plurality of circular rings 15, and the plurality of circular rings 15 are arranged in parallel, and the circular rings 15 have a supporting function.
