[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 An infant urine collection device is described. To ensure the safety of the device, the sealing sheet 17 needs to be torn open during use. However, after tearing open the sealing sheet 17, the inner surface of the disposable urine bag 11 should not be touched with items that may carry viruses, otherwise there is a risk of viral infection of the urethra.

[0020] To improve the success rate of urine collection, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3and Figure 4 An adhesive urine collection mechanism is required, comprising a disposable urine bag 11 for storing urine, an adhesive ring 16 at the opening of the disposable urine bag 11 that can be adhered to the skin, a unidirectional moisture-wicking fabric 110 in the middle area of ​​the disposable urine bag 11 that controls the unidirectional flow of liquid, and a rubber sealing sheet 111 at the drain port of the disposable urine bag 11 that prevents urine leakage. The sealing sheet 17 is torn off, and then the adhesive ring 16 is to be attached to the skin surrounding the infant's private parts. It is important to note that the infant's urethra is completely enclosed within the funnel-shaped collection chamber 12. At this point, the disposable urine bag 11 can move with the infant and will not cause any discomfort to the infant. This method avoids significant movement obstruction for infants. When an infant urinates, the urine first collects inside the funnel-shaped collection chamber 12. Due to the presence of the adhesive ring 16, urine leakage is prevented. Under the influence of gravity, the urine flows through the one-way moisture-wicking fabric 110 into the spherical storage chamber 14 and is eventually stored there. During movement, the urine does not flow back through the one-way moisture-wicking fabric 110, thus improving the success rate of urine collection. However, caregivers need to check the urine volume regularly. Excessive urine volume can cause discomfort or even pain for the infant. Once an appropriate amount of urine has been collected, the disposable urine bag 11 can be torn off from the infant's skin to obtain the appropriate amount of urine.

[0021] For details regarding the specific structure of the adhesive urine collection mechanism, please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 It also includes a funnel-shaped collection cavity 12 with an open top, disposed inside the disposable urine bag 11. The disposable urine bag 11 has a central drainage cavity 13 at the bottom end of the funnel-shaped collection cavity 12, and a spherical storage cavity 14 at the bottom end of the central drainage cavity 13. The disposable urine bag 11 has a drain outlet 15 at the bottom end of the spherical storage cavity 14 for discharging urine. An adhesive ring 16 is attached to the upward end face of the disposable urine bag 11 located in the funnel-shaped collection cavity 12, and a sealing sheet 17 is attached to the upper surface of the adhesive ring 16. The disposable urine bag 11 has a circumference of the central drainage cavity 13... An upper fixing ring 18 is fixedly installed on the inner wall, and a one-way moisture-wicking fabric 110 is embedded in the middle of the upper fixing ring 18. A lower fixing ring 19 is fixedly installed on the inner circumference of the disposable urine bag 11 located at the drain port 15. A limiting insertion cavity 112 is provided in the center of the lower fixing ring 19. A rubber sealing sheet 111 is embedded in the top port of the lower fixing ring 19. When the sealing sheet 17 is not torn off, it can seal the opening end of the funnel-shaped collection cavity 12. The one-way moisture-wicking fabric 110 can control the urine to enter the spherical storage cavity 14 unidirectionally from the funnel-shaped collection cavity 12. The rubber sealing sheet 111 is a sheet structure made of rubber material.

[0022] To extract urine samples, please refer to [link / reference]. Figure 5 and Figure 6 A piston-type sampling mechanism is required, which includes a sampling cylinder 21 that can be inserted into the limiting insertion cavity 112 and has a hollow interior; a needle 23 that can pierce the rubber sealing sheet 111 and connect to the internal structure of the sampling cylinder 21; a piston plate 26 placed inside the sampling cylinder 21 and capable of drawing urine into the sampling cylinder 21; and a pull rod 27 that can drive the piston plate 26 to move axially. The top of the urine is drawn into the sampling cylinder 21 and inserted into the limiting insertion cavity 112, causing the needle 23 to pierce the rubber sealing sheet 111 until the top of the needle 23 enters the spherical storage cavity 14. Then, the force cap 28 is pulled down, and under the drive of the power, the piston plate 26 will move downward, and the urine located inside the spherical storage cavity 14 will be drawn into the sampling cavity 22, thereby realizing the extraction of urine samples.

[0023] For details regarding the specific structure of the piston-type sampling mechanism, please refer to [link / reference]. Figure 5 and Figure 6 It also includes a sampling cavity 22 disposed inside the sampling cylinder 21. The top of the sampling cylinder 21 is provided with a needle 23 communicating with the sampling cavity 22. The bottom center of the sampling cylinder 21 is provided with a rod through-hole 24 communicating with the space below it and the bottom of the sampling cavity 22. The bottom end of the sampling cylinder 21 is provided with a vent hole 25 for gas flow. A piston plate 26 capable of moving axially along the sampling cavity 22 is placed inside the sampling cylinder 21 within the sampling cavity 22. A pull rod 27 with a through hole 24 is fixedly installed at the bottom end of the plug plate 26. A force cap 28 is fixedly installed at the bottom end of the pull rod 27. A chamfer structure is provided at the top corner of the sampling cylinder 21 to facilitate its insertion into the limiting insertion cavity 112. The cross-sectional shape of the rod through hole 24 is consistent with the cross-sectional shape of the pull rod 27, both being polygonal structures. The cross-sectional dimensions of the rod through hole 24 match the cross-sectional dimensions of the pull rod 27.

[0024] When using, tear open the sealing sheet 17, and then stick the adhesive ring 16 to the skin surrounding the infant's private parts. Note that the infant's urethra is completely enclosed inside the funnel-shaped collection chamber 12. The disposable urine bag 11 can move with the infant without significantly hindering their movement. When the infant urinates, the urine first collects inside the funnel-shaped collection chamber 12. Due to the adhesive ring 16, leakage is prevented. Under gravity, the urine flows through the one-way moisture-wicking fabric 110 into the spherical storage chamber 14, where it is finally stored. During movement, the urine does not flow through the one-way moisture-wicking fabric 110. 10. Backflow can improve the success rate of urine collection. However, caregivers need to check the urine volume regularly. Excessive urine volume can cause discomfort or even pain in infants. After collecting an appropriate amount of urine, the disposable urine bag 11 can be torn off from the infant's skin to obtain an appropriate amount of urine. The urine is then drawn into the top of the sampling tube 21 and inserted into the limiting insertion cavity 112, so that the needle 23 pierces the rubber sealing sheet 111 until the top of the needle 23 enters the spherical storage cavity 14. Then, the force cap 28 is pulled down. Under the drive of the power, the piston plate 26 will move downward, and the urine inside the spherical storage cavity 14 will be drawn into the sampling cavity 22, thereby realizing the extraction of urine samples.
