Description

Technical Field

[0001] This invention belongs to the field of urinary ostomy bags, specifically a urinary ostomy bag and its method of use. Background Technology

[0002] Uroscopic bags are essential medical aids for patients with urinary tract stomas after surgery. In clinical medicine, due to various urinary system diseases, such as bladder cancer, severe urethral injury, and congenital urinary system malformations, patients' normal urination function suffers irreversible damage. In order to maintain life, health, and normal life, it is often necessary to surgically construct an artificial urinary tract stoma in the abdomen or other locations, allowing urine to bypass the damaged urinary organs and be discharged through the stoma.

[0003] The main function of a urinary ostomy bag is to collect urine discharged from the stoma. It not only provides patients with a safe and hygienic urine storage container, avoiding the pollution of skin, clothing and the surrounding environment caused by urine leakage, but also helps patients better manage urine, maintain the normal order of daily life, thereby significantly improving patients' quality of life and mental state, and reducing the physical and mental burden caused by the disease.

[0004] Currently, when draining urine from a urostomy bag, the cap needs to be removed; after drainage, the cap must be replaced. However, this design is prone to contamination during actual use. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a urinary ostomy bag to solve the issues of cumbersome operation and easy contamination in existing plugging designs, which fail to meet patients' needs for convenient and hygienic urine drainage.

[0006] A urinary ostomy bag includes an ostomy bag assembly, an export connector assembly, and an on / off valve assembly;

[0007] The export connector assembly includes an export connector body, one end of which is fixed with a threaded ring, and the other end of which is fixed with a hollow cylinder. An export tube is fixed to the outside of the export connector body, and the threaded ring and the ostomy bag assembly are fixed and connected.

[0008] The valve assembly includes a valve stem, one end of which has a guide groove, and the other end of which is fixed with a pull ball. A limit ring is also fixed to the outside of the valve stem, and a spring is sleeved on the outside of the valve stem.

[0009] The limiting ring and spring limiting sliding are embedded in the hollow cylinder, the pull ball is located away from the outlet connector body, and the spring drives the limiting ring to move towards the outlet connector body;

[0010] When the ball is pulled, the valve stem moves, which connects the guide groove and the outlet pipe. At the same time, the limit ring moves synchronously and compresses the spring.

[0011] When the ball is released, the spring returns to its original position, causing the limit ring to move, which in turn moves the valve stem, causing the guide groove and the outlet pipe to separate from each other.

[0012] Preferably, an L-shaped bracket is also fixed to the outside of the valve stem, and the end of the L-shaped bracket is provided with a movable groove;

[0013] The L-shaped bracket slides on the outside of the outlet pipe via a movable groove, thereby restricting the rotation of the valve stem.

[0014] Preferably, a positioning bracket is also fixed to the outer side of the L-shaped bracket;

[0015] A retaining ring is fixed to the outside of the outlet tube;

[0016] It also includes an external outlet tube assembly, which includes an external outlet tube body. A second retaining ring is fixed to the outer side of one end of the external outlet tube body. One end of the external outlet tube body is sleeved on the outer side of the outlet tube, so that the second retaining ring is inserted into the first retaining ring.

[0017] When the L-shaped bracket moves, the positioning bracket moves along with it and abuts against the second retaining ring, thereby preventing the second retaining ring from being pulled out.

[0018] Preferably, the ostomy bag assembly includes an ostomy bag body, a base plate is provided on the outer side of the ostomy bag body, and an external drainage port is provided at one end of the ostomy bag body.

[0019] Preferably, the ostomy bag body is further provided with an internal drainage port.

[0020] Preferably, when the ball is pulled to its maximum stroke, the guide groove is fully connected to the outlet tube, and the spring is in its maximum compression state;

[0021] When the ball is in a naturally unpulled state, the guide groove is completely separated from the outlet tube, and the spring is in a naturally extended state.

[0022] Preferably, the threaded ring and the ostomy bag assembly are fixed and connected by sealant to ensure the sealing of the connection.

[0023] Preferably, a rubber sealing ring is provided at the contact point between the second retaining ring and the first retaining ring to enhance the sealing performance at the connection between the external outlet tube body and the outlet tube.

[0024] Preferably, the base plate is fixed to the ostomy bag body by heat fusion bonding, and the edges of the base plate are rounded to reduce friction on the user's skin.

[0025] A method for using a urinary ostomy bag includes the following steps:

[0026] S1. Installation preparation: Put one end of the external outlet tube body on the outside of the outlet tube, and insert the second retaining ring into the first retaining ring.

[0027] S2. Adhesion and Fixation: Adhere the base plate to the appropriate skin position around the patient's stoma. When adhering, ensure that the base plate fits tightly to the skin without wrinkles or air bubbles.

[0028] S3, Urine Drainage: When urine needs to be drained, pull the ball by hand. The ball moves the valve stem. At this time, the limit ring moves synchronously in the hollow cylinder and compresses the spring. When the ball is pulled to the maximum stroke, the guide groove and the drainage tube are fully connected. Urine can flow out smoothly from the ostomy bag body through the drainage connector body and the drainage tube.

[0029] Pulling the ball will also cause the L-shaped bracket to move, which in turn causes the positioning bracket to abut against the second retaining ring, preventing the second retaining ring from being pulled out and ensuring a stable connection between the external tube body;

[0030] S4. Close the drain: After the urine is drained, release the ball, and the spring resets and drives the limit ring to move toward the drain connector body, which in turn moves the valve stem. When the ball is in a natural unpulled state, the guide groove and the drain tube are completely separated, preventing urine from continuing to flow out.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] By designing a connection and separation mechanism between the guide groove at one end of the valve stem and the outlet tube in the valve assembly, urine drainage operations become more convenient and efficient. When urine needs to be drained, simply pull the ball to move the valve stem, which connects the guide groove with the outlet tube, allowing urine to flow smoothly from the ostomy bag assembly and avoiding discomfort caused by urine accumulation. After drainage is complete, releasing the ball separates the guide groove from the outlet tube, preventing further urine flow and achieving automatic closure. This is convenient, hygienic, and greatly enhances the patient's experience.

[0033] By fixing an L-shaped bracket with a movable groove to the outside of the valve stem and allowing the movable groove to slide on the outside of the outlet pipe, the rotation of the valve stem is cleverly restricted. When the ball is pulled to move the valve stem, the valve stem can only reciprocate along a straight line, which ensures that the guide groove can accurately connect or disconnect with the outlet pipe.

[0034] Using a positioning bracket fixed to the outside of the L-shaped support, when the external discharge tube body is sleeved on the outside of the discharge tube and the second retaining ring is inserted into the first retaining ring, the positioning bracket moves with the L-shaped support and abuts against the second retaining ring. This design effectively prevents the second retaining ring from being accidentally pulled out, enhances the firmness of the connection between the external discharge tube body and the discharge tube, prevents the external discharge tube body from falling off during use, and ensures that urine can be continuously and stably discharged, providing patients with more reliable usage protection.

[0042] 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.

[0043] like Figures 1 to 5 As shown:

[0044] Example 1: The present invention provides a urinary ostomy bag, including an ostomy bag assembly 1, an export connector assembly 2, and an opening and closing valve assembly 3;

[0045] The export connector assembly 2 includes an export connector body 21, one end of which is fixed with a threaded ring 22, the other end of which is fixed with a hollow cylinder 23, and an export tube 24 fixed to the outside of the export connector body 21. The threaded ring 22 and the ostomy bag assembly 1 are fixed and connected.

[0046] The valve assembly 3 includes a valve stem 31, one end of which is provided with a guide groove 32, and the other end of which is fixed with a pull ball 33. A limit ring 34 is also fixed on the outside of the valve stem 31, and a spring 35 is sleeved on the outside of the valve stem 31.

[0047] The limiting ring 34 and spring 35 are locked and slidably embedded in the hollow cylinder 23. The pull ball 33 is located away from the outlet connector body 21. The spring 35 drives the limiting ring 34 to move toward the outlet connector body 21.

[0048] When the ball 33 is pulled, the valve stem 31 moves, which makes the guide groove 32 and the outlet pipe 24 connect with each other. At the same time, the limit ring 34 moves synchronously and compresses the spring 35.

[0049] When the ball 33 is released, the spring 35 returns to its original position, causing the limit ring 34 to move, which in turn moves the valve stem 31, causing the guide groove 32 and the outlet pipe 24 to separate from each other.

[0050] As can be seen from the above, during use, when urine needs to be drained, the user pulls the pull ball 33, which moves the valve rod 31, so that the guide groove 32 at one end of the valve rod 31 is connected to the drain tube 24. At this time, urine can flow smoothly from the ostomy bag assembly 1 through the drain connector body 21 and the drain tube 24. The operation is simple and the flow is smooth, effectively avoiding the discomfort caused by urine accumulation.

[0051] During the process of pulling the ball 33, the limiting ring 34 on the outside of the valve stem 31 will move synchronously inside the hollow cylinder 23, while compressing the spring 35 sleeved on the outside of the valve stem 31. The compression of the spring 35 provides power for the subsequent reset action, and the sliding and locking design of the limiting ring 34 and the hollow cylinder 23 ensures the stability of the movement of the valve stem 31, making the conduction operation more precise and reliable.

[0052] Once the urine has been drained, the user releases the pull ball 33. At this time, the compressed spring 35 returns to its original position, driving the limit ring 34 to move towards the drain connector body 21, which in turn moves the valve stem 31, causing the guide groove 32 and the drain tube 24 to separate from each other, preventing urine from continuing to flow out. This achieves automatic shut-off of urine drainage, which is both convenient and hygienic, greatly improving the patient's user experience.

[0053] like Figure 5 As shown:

[0054] Specifically, when the ball 33 is pulled to its maximum stroke, the guide groove 32 is fully connected to the outlet tube 24, and the spring 35 is in its maximum compression state.

[0055] When the ball 33 is in a naturally unpulled state, the guide groove 32 is completely separated from the outlet tube 24, and the spring 35 is in a naturally extended state.

[0056] Specifically, a rubber sealing ring is provided at the contact point between the second retaining ring 42 and the first retaining ring 25 to enhance the sealing performance at the connection between the external outlet tube body 41 and the outlet tube 24.

[0057] As can be seen from the above, when the ball 33 is pulled to its maximum stroke, the guide groove 32 and the outlet tube 24 are fully connected, and the spring 35 is in the maximum compression state.

[0058] When the pull ball 33 is in a naturally unpulled state, the guide groove 32 is completely separated from the outlet tube 24, and the spring 35 returns to its naturally extended state. At this time, urine cannot flow out, thus achieving precise urine outlet control.

[0059] The rubber sealing ring at the contact point between the second retaining ring 42 and the first retaining ring 25 greatly enhances the sealing performance at the connection between the external discharge tube body 41 and the discharge tube 24. This effectively prevents urine leakage from the connection point, avoiding potential clothing stains and skin irritation caused by urine leakage, further improving the overall performance of the urostomy bag, and providing patients with a more reliable and safer user experience.

[0060] Example 2: This example is basically the same as the previous example, except that, as Figure 4 and 5 As shown: It also includes an L-shaped bracket 36 fixed on the outside of the valve stem 31, and an movable groove 37 is provided at the end of the L-shaped bracket 36;

[0061] The L-shaped bracket 36 slides on the outside of the outlet pipe 24 via the movable groove 37, thereby restricting the rotation of the valve stem 31.

[0062] Specifically, a positioning bracket 38 is also fixed to the outside of the L-shaped bracket 36;

[0063] A retaining ring 25 is fixed to the outside of the outlet tube 24;

[0064] It also includes an external outlet tube assembly 4, which includes an external outlet tube body 41. A retaining ring 2 42 is fixed to the outer side of one end of the external outlet tube body 41. One end of the external outlet tube body 41 is sleeved on the outer side of the outlet tube 24, so that the retaining ring 2 42 is inserted into the retaining ring 1 25.

[0065] When the L-shaped bracket 36 moves, the positioning bracket 38 moves along with it and abuts against the second retaining ring 42, thereby preventing the second retaining ring 42 from being pulled out.

[0066] As can be seen from the above, during use, when the pull ball 33 moves the valve stem 31, the L-shaped bracket 36 fixed on the outside of the valve stem 31 moves synchronously, and the movable groove 37 at its end slides along the outside of the outlet tube 24. This restricts the rotation of the valve stem 31, so that the valve stem 31 can only reciprocate along a straight line, thereby ensuring that the guide groove 32 can accurately connect or separate from the outlet tube 24, greatly improving the stability and accuracy of the urine outlet operation, and avoiding problems such as poor flow or poor sealing caused by the rotation of the valve stem 31.

[0067] As the L-shaped bracket 36 moves, the positioning bracket 38 fixed to its outer side also moves accordingly. When the external discharge tube body 41 is fitted over the outside of the discharge tube 24, and the second retaining ring 42 is inserted into the first retaining ring 25, the positioning bracket 38 will abut against the second retaining ring 42 during movement. This abutting action effectively restricts the second retaining ring 42 from being accidentally pulled out, enhances the firmness of the connection between the external discharge tube body 41 and the discharge tube 24, prevents the external discharge tube body 41 from falling off during use, and ensures that urine can be continuously and stably discharged, providing patients with more reliable usage protection;

[0068] When the urine discharge operation is completed and the valve stem 31 is reset by releasing the pull ball 33, the L-shaped bracket 36 and the positioning bracket 38 will also return to their initial positions simultaneously. At this time, the guide groove 32 separates from the discharge tube 24, and the urine flow stops.

[0069] Example 3: This example is basically the same as the previous example, except that, as Figure 6 As shown: It also includes an ostomy bag assembly 1, which includes an ostomy bag body 11, a base plate 12 on the outside of the ostomy bag body 11, and an external drainage port 13 at one end of the ostomy bag body 11.

[0070] Specifically, the ostomy bag body 11 is also provided with an internal drainage port 14.

[0071] Specifically, the threaded ring 22 is fixed and connected to the ostomy bag assembly 1 with sealant to ensure the sealing of the connection.

[0072] Specifically, the base 12 is fixed to the ostomy bag body 11 by heat fusion bonding, and the edges of the base 12 are rounded to reduce friction on the user's skin.

[0073] As can be seen from the above, when urine is produced in the body and flows into the ostomy bag assembly 1, the urine first enters the ostomy bag body 11. The internal drainage port 14 set inside the ostomy bag body 11 can guide the urine and prevent backflow. Then, the urine flows out through the external drainage port 13 at one end of the ostomy bag body 11 to the outlet connector assembly 2. This makes the flow path of urine more reasonable, effectively avoids urine residue in the ostomy bag body 11, reduces odor, and improves the hygiene and comfort of patients during use.

[0074] The outlet connector assembly 2 is connected to the ostomy bag assembly 1 via a threaded ring 22, and the threaded ring 22 and the ostomy bag assembly 1 are fixed and connected by sealant. During the process of urine flowing from the external drainage port 13 to the outlet connector assembly 2, the sealant ensures that there will be no urine leakage at the connection, ensuring the sealing of the entire drainage system. This eliminates the embarrassment and inconvenience caused by urine leakage for patients, making it more reassuring to use.

[0075] The base plate 12 on the outer side of the ostomy bag body 11 is tightly fixed to the ostomy bag body 11 by heat fusion bonding, and the edges of the base plate 12 are rounded. When the urinary ostomy bag is attached to the patient's body, the rounded edges of the base plate 12 can greatly reduce friction on the user's skin, avoid discomfort such as skin redness and pain caused by long-term friction, improve the patient's wearing comfort, and enable the patient to use the urinary ostomy bag normally for a longer period of time.
