This field integrates knowledge from multiple disciplines, including biology, engineering, and information technology, and covers the entire process from basic research to clinical application, including but not limited to medical devices, drug delivery systems, imaging technologies, in vitro diagnostics, rehabilitation aids, and telemedicine platforms.

[0003] A urine collection bag is a medical device used to collect and store urine discharged through a catheter. It is suitable for patients who are unable to urinate independently or require continuous monitoring of urine output. It typically features a leak-proof interface, a transparent bag for observing urine flow, precise measurement scales, and an easy-to-empty design, ensuring safety, hygiene, and ease of management. Urine collection bags are widely used in hospitals, home care, and long-term care facilities, providing an effective urine management solution while helping to prevent infection and supporting healthcare professionals in making accurate clinical assessments.

[0004] In the existing technology, urine collection bags are usually used for personnel sampling or drainage through the drain valve at the bottom. Although this meets the needs to a certain extent, it has been found in actual use that when the drain valve at the bottom of the urine collection bag is opened, a large amount of urine will flow out of the bag under the action of gravity. The urine will flow out quickly, making it difficult to accurately control the flow rate and volume, which may lead to liquid overflow or splashing. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a urine collection bag, including a urine collection bag body 1, an inlet valve 2 fixedly connected to the top of the urine collection bag body 1, a conduit 5 fixedly connected to the top of the inlet valve 2, a connecting mechanism 6 fixedly connected to one end of the conduit 5, an outlet valve 3 fixedly connected to the top of the urine collection bag body 1, and an outlet pipe 4 fixedly connected to the top of the outlet valve 3. The inlet valve 2 and the outlet valve 3 have the same structure. The inlet valve 2 includes a valve body 201, a horizontal tube 202 fixedly installed inside the valve body 201, a slide rod 203 slidably installed inside the horizontal tube 202, a through hole 204 opened inside the slide rod 203, two sets of limiting posts 206 fixedly installed on the inner wall of the horizontal tube 202, and two sets of limiting grooves 207 opened on the outer wall of the slide rod 203. The cross-sections of the limiting posts 206 and the limiting grooves 207 are equal, and the limiting posts 206 are slidably installed on the inner wall of the limiting grooves 207.

[0023] Pull tabs 10 are fixedly installed on both the front and rear sides of the urine collection bag body 1. Through the pull tabs 10, personnel can pull the residual liquid inside the outlet tube 4 back into the urine collection bag body 1 by pulling the bag body of the urine collection bag body 1.

[0024] Two sets of sealing rings 208 are fitted on the outer wall of the slide rod 203. The two sets of sealing rings 208 are respectively set on the left and right sides of the through hole 204. The sealing rings 208 ensure the sealing between the slide rod 203 and the horizontal tube 202.

[0025] Limiting plates 205 are fixedly installed on both the left and right sides of the slide rod 203. The maximum displacement distance of the slide rod 203 on the inner wall of the horizontal tube 202 is limited by the two sets of limiting plates 205.

[0026] The specific implementation method is as follows: Liquid flows through the inside of the valve body 201. The alignment of the through hole 204 with the valve body 201 is controlled by pushing the slide rod 203, thus controlling the unobstructed flow of the internal pipes of the valve body 201. The displacement direction of the slide rod 203 is limited by the cooperation between the limiting post 206 and the limiting groove 207, ensuring that the central axis of the through hole 204 is parallel to the valve body 201. The inlet valve 2 controls whether liquid can enter the interior of the urine collection bag body 1, and the outlet valve 3 controls whether the liquid inside the urine collection bag body 1 can be discharged through the outlet pipe 4. When sampling is required, simply close the inlet valve 2 and open the outlet valve 3, then squeeze the urine collection bag body 1 to discharge urine through the outlet valve 3 and the outlet pipe 4. This device discharges liquid by manual squeezing, requiring only control of the squeezing force for relatively accurate liquid collection, thus solving the problem of inaccurate liquid collection in existing technologies.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a urine collection bag, the connecting mechanism 6 includes a tower-type connector 601, an installation sleeve 602 is fixedly installed on the inner wall of the tower-type connector 601, a retaining ring 603 is fixedly installed inside the installation sleeve 602, an installation frame 604 is fixedly installed inside the installation sleeve 602, an installation rod 605 is slidably installed inside the installation frame 604, a baffle 606 is fixedly connected to the bottom of the installation rod 605, and a spring 607 is sleeved on the outer wall of the installation rod 605, the spring 607 is disposed between the baffle 606 and the installation frame 604;

[0028] A pipe clamp 7 is fitted on the outer wall of the liquid outlet valve 3, which allows personnel to easily fix the liquid collection test tube to the bottom of the liquid outlet pipe 4.

[0029] A hanging ring 8 is fixedly installed on the top of the urine collection bag body 1, and two sets of elastic straps 9 are fixedly installed on one side of the urine collection bag body 1. The hanging ring 8 makes it convenient for users to hang the urine collection bag body 1 on the hook, and the elastic straps 9 make it convenient for users to tie the urine collection bag body 1 to the column.

[0030] The specific implementation method is as follows: the spring 607 provides elastic force to the baffle 606 toward the baffle ring 603, and the cooperation between the baffle 606 and the baffle ring 603 blocks the channel inside the mounting sleeve 602. The conduit 5 is connected to the drainage tube through the tower connector 601. In summary, the liquid can only flow into the interior of the conduit 5 from the connecting mechanism 6 by overcoming the elastic force of the spring 607, and cannot flow out of the top of the connecting mechanism 6 through the conduit 5. This device has an anti-backflow function to prevent urine from flowing back into the bladder and reduce the risk of infection.

[0031] Working principle: When using this urine collection bag, the liquid flows through the inside of the valve body 201. By pushing the slide rod 203, the alignment of the through hole 204 with the valve body 201 is controlled, thus controlling whether the internal pipe of the valve body 201 is unobstructed. The displacement direction of the slide rod 203 is restricted by the cooperation between the limiting post 206 and the limiting groove 207, ensuring that the central axis of the through hole 204 is parallel to the valve body 201. The liquid inlet valve 2 controls whether the liquid can enter the inside of the urine collection bag body 1, and the liquid outlet valve 3 controls whether the liquid inside the urine collection bag body 1 can be discharged through the liquid outlet pipe 4. When sampling is required, simply close the liquid inlet valve 2 and open the liquid outlet valve 3, and then squeeze the urine collection bag body 1 to discharge the urine through the liquid outlet valve 3 and the liquid outlet pipe 4. This equipment discharges liquid by manual squeezing, and only the squeezing force needs to be controlled to accurately collect liquid, solving the problem of inaccurate liquid collection in the prior art.

[0032] The pull tab 10 allows personnel to draw the residual liquid inside the outlet tube 4 back into the urine collection bag body 1 by stretching the bag body 1. The sealing ring 208 ensures the sealing between the slide rod 203 and the horizontal tube 202. The two sets of limiting plates 205 limit the maximum displacement distance of the slide rod 203 on the inner wall of the horizontal tube 202.

[0033] The spring 607 provides elastic force to the baffle 606 towards the baffle ring 603, and the cooperation between the baffle 606 and the baffle ring 603 blocks the channel inside the mounting sleeve 602. The conduit 5 is connected to the drainage tube through the tower connector 601. In summary, the liquid can only flow into the inside of the conduit 5 from the connecting mechanism 6 by overcoming the elastic force of the spring 607, and cannot flow out of the top of the connecting mechanism 6 through the conduit 5. This device has an anti-backflow function to prevent urine from flowing back into the bladder and reduce the risk of infection.

[0034] The tube clamp 7 allows personnel to easily fix the liquid collection tube to the bottom of the liquid outlet tube 4, the hanging ring 8 allows personnel to easily hang the urine collection bag body 1 on the hook, and the elastic strap 9 allows personnel to easily tie the urine collection bag body 1 to the column.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
