Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a three-way valve structure for a urine bag. Background Technology

[0002] A urine bag is a medical device used to collect and store urine. For patients who require long-term indwelling catheters due to their condition, such as those who are unable to urinate independently after surgery or are in a coma, a urine bag can continuously collect urine, allowing medical staff to accurately record urine volume, observe changes in urine, assist in diagnosis, and perform corresponding medical and nursing procedures.

[0003] The three-way valve for urine bags is a key component used in urine bag systems, possessing multiple functions and enabling connections to different pipelines and control of urine flow direction. Existing three-way valve structures use a closed cavity with a rotating valve core to switch flow paths. This method of valve core switching involves frequent rotation within the closed cavity, causing long-term friction at the contact points with the cavity, which can easily lead to wear of the sealing material. In practical use, due to limitations in manufacturing precision and other factors, it is difficult to ensure a completely tight and seamless fit between the valve core and the cavity. Therefore, we propose a new three-way valve structure for urine bags. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a three-way valve structure for urine bags to solve the technical problem that the sealing performance of the current three-way valve for valve core switching is easily affected by external factors, resulting in poor sealing performance.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a three-way valve structure for a urine bag, including a valve tube, an adjusting component, and a diversion component. An inlet pipe is installed through the upper end of the valve tube, a drain pipe is installed through the inner side of the lower end of the valve tube, and a diversion pipe is installed through the outer side of the middle section of the valve tube, with an end cap inserted into the lower end of the diversion pipe. The adjusting component is installed at the bottom of the valve tube and consists of a lifting cylinder, a screw, and a knob. The knob is rotatably installed at the bottom end of the valve tube, and the screw is rotatably installed inside the valve tube at the bottom end, connected to the knob. The diversion component is installed in the middle of the inside of the valve tube and consists of a hood and a cone hood. The upper opening of the hood corresponds to the inlet pipe, and a waist cavity is formed between the hood and the cone hood.

[0006] In use, the catheter and urine bag are connected to the inlet and outlet pipes, respectively. When switching pathways, rotating the knob controls the lifting cylinder via a screw thread. The lifting cylinder rises, squeezing the bottom of the cone shroud, causing the bottom of the cone shroud to unfold and fit against the inner wall of the valve pipe. At this point, the pathway switches to the diversion pipe. When the normal pathway is open, urine slides down the inclined surface of the cone shroud, flowing through the gap between the bottom of the cone shroud and the inner wall of the valve pipe, allowing the urine to be discharged from the outlet pipe. Through the above structural design, this device uses a squeezing method combined with the unique conical structure of the cone shroud to switch pathways, avoiding reduced sealing due to fit and wear issues, thus ensuring the device's effectiveness. During sampling, after removing the end cap, connect the sampling bottle to the threaded end of the diversion tube. Manually control the lifting cylinder to rise and squeeze the bottom of the cone, reducing the gap between its bottom and the inner wall of the valve tube. When the drainage gap is reduced, the patient's urine accumulates in the lumbar region during the urination process. Some urine enters the sampling bottle through the diversion tube. When the sampling bottle is full, it does not affect normal urination, preventing urine from remaining in the tubing for a long time due to failure to switch the pathway in time. When flushing with medication, the drainage tube can be completely closed to allow the medication to enter the bladder smoothly. Through the above structural design, this device can switch between different working modes through the internal diversion component. The three working modes improve the overall practicality of the device.

[0007] Preferably, the diverter is L-shaped, with a flat opening at the bottom and clips fixed on both sides of the flat opening. A threaded joint is provided between the diverter and the flat opening, and the diverter connects to the waist cavity.

[0008] Preferably, the end cap is inserted into the flat pipe opening, a plug is fixed inside the end cap, slots are provided on both sides of the end cap, a sloping pressing surface is provided at the lower end of the buckle, an inwardly inclined buffer end is provided on the inner side of the upper end of the buckle, and the buckle is connected to the slot.

[0009] Preferably, the outer side of the lifting cylinder is provided with a flow guide in the annular array, the valve tube is fixed with limit strips on both sides inside, and the limit strips are slidably connected with the flow guide inlet, and the upper end of the screw thread passes through the middle of the lifting cylinder.

[0010] Preferably, the upper end of the cone is inserted and fixed inside the bottom opening of the hood, and the lower opening of the hood is provided with a ring array of diversion ports, which are in contact with the outer inclined surface of the cone.

[0011] Preferably, the bottom of the cone cover has a bottom opening that corresponds to the lifting cylinder, the distance between the outer edge of the bottom of the cone cover and the inner wall of the valve pipe is one centimeter, and both the hood and the cone cover are made of silicone material.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of an adjustment component, allows for channel switching by rotating a knob, which controls the lifting cylinder via a screw thread. The lifting cylinder rises and squeezes the bottom of the cone shroud, causing the bottom of the cone shroud to unfold and fit against the inner wall of the valve tube. At this time, the flow is switched to the diversion pipe. When the normal flow is open, urine slides down the inclined surface of the cone shroud and is guided through the gap between the bottom of the cone shroud and the inner wall of the valve tube, allowing the urine to be discharged from the drain pipe. Through the above structural design, this device achieves channel switching through a squeezing method combined with the unique conical structure design of the cone shroud, and avoids reduced sealing due to fit and wear issues, ensuring the effectiveness of the device.

[0013] 2. This utility model also incorporates a diversion component. When sampling is required, the end cap is removed, and the sampling bottle is threaded onto the diversion tube. The lifting cylinder is manually controlled to rise and squeeze the bottom of the cone, reducing the gap between its bottom and the inner wall of the valve tube. As the diversion gap decreases, the patient's urine accumulates in the lumbar region during urination. Some urine enters the sampling bottle through the diversion tube. When the sampling bottle is full, it does not affect normal urination, preventing urine from remaining in the tubing for an extended period due to failure to switch the flow path in time. When flushing with medication, the drainage tube can be completely closed, allowing the medication to enter the bladder smoothly. Through the above structural design, this device can switch between different working modes through the internal diversion component. The three working modes improve the overall practicality of the device. Attached Figure Description

[0016] like Figures 1 to 4 As shown, this utility model relates to a three-way valve structure for a urine bag, including a valve tube 1, an adjusting component 4, and a diversion component 5. An inlet pipe 101 is installed through the upper end of the valve tube 1, and a drain pipe 103 is installed through the inner side of the lower end of the valve tube 1. A diversion pipe 2 is installed through the outer side of the middle section of the valve tube 1, and an end cap 3 is inserted into the lower end of the diversion pipe 2. The adjusting component 4 is installed at the bottom of the valve tube 1 and consists of a lifting cylinder 401, a screw 403, and a knob 404, which is rotatably mounted at the bottom of the valve tube 1. The screw 403 is rotatably installed inside the bottom of the valve pipe 1, and the screw 403 is connected to the knob 404. The diverter pipe 2 is L-shaped, and the bottom of the diverter pipe 2 is provided with a flat pipe opening 201. Both sides of the flat pipe opening 201 are fixed with buckles 202. A screw 203 is provided between the diverter pipe 2 and the flat pipe opening 201. The diverter pipe 2 connects to the waist cavity 503. The end cap 3 is inserted into the flat pipe opening 201. A plug 302 is fixed inside the end cap 3. Both sides of the end cap 3 are provided with slots 301. The lower end of the buckle 202 is provided with a beveled pressure surface 204. The upper inner side of the buckle 202 is provided with an inwardly inclined buffer end 205. The buckle 202 is connected to the slot 301. The outer side of the lifting cylinder 401 has a ring array of guide ports 402. The valve pipe 1 has limit strips 102 fixed on both sides inside, and the limit strips 102 are slidably connected to the guide ports 402. The upper end of the screw 403 is threaded through the middle of the lifting cylinder 401. When switching the passage, rotating the knob 404 controls the lifting cylinder 401 through the screw 403 thread. The lifting cylinder 401 rises and squeezes the bottom opening 50 of the cone cover 504. 5. The bottom of the cone shroud 504 is unfolded to fit the inner wall of the valve tube 1. At this time, the flow path is switched to the diversion tube 2. When the normal flow path is open, the urine slides down the inclined surface of the outer side of the cone shroud 504 and is guided through the gap between the bottom of the cone shroud 504 and the inner wall of the valve tube 1, so that the urine is discharged from the drain tube 103. Through the above structural design, the device can switch the flow path by means of compression in conjunction with the unique conical structure design of the cone shroud 504, and avoid the reduction of sealing performance caused by fit and wear problems, so as to ensure the effectiveness of the device.

[0017] like Figures 2 to 6As shown, this utility model relates to a three-way valve structure for a urine bag, including a valve tube 1, an adjusting component 4, and a diversion component 5. The diversion component 5 is installed in the middle of the valve tube 1 and consists of a hood 501 and a cone hood 504. The upper opening of the hood 501 corresponds to the inlet pipe 101, and a waist cavity 503 is formed between the hood 501 and the cone hood 504. The upper end of the cone hood 504 is inserted and fixed inside the bottom opening of the hood 501. A diversion port 502 is arranged in a ring array at the lower opening of the hood 501, and the diversion port 502 fits against the outer inclined surface of the cone hood 504. The bottom of the cone hood 504 has a bottom opening 505, which corresponds to the lifting cylinder 401. The distance between the outer edge of the bottom of the cone hood 504 and the inner wall of the valve tube 1 is one centimeter. Both the hood 501 and the cone hood 504 are... Made of silicone, when sampling is required, after removing the end cap 3, the sampling bottle is threaded to the threaded port 203 of the diversion tube 2. The lifting cylinder 401 is manually controlled to rise and squeeze the bottom port 505 of the cone shroud 504, reducing the gap between its bottom and the inner wall of the valve tube 1. When the drainage gap is reduced, the patient's urine accumulates in the lumbar cavity 503 during the urination drainage process. Some urine enters the sampling bottle through the diversion tube 2. When the sampling bottle is full, it does not affect normal urination, preventing urine from remaining in the pipeline for a long time due to failure to switch the pathway in time. When flushing with medicine, the drainage tube 103 can be completely closed to allow the medicine to enter the bladder smoothly. Through the above structural design, the device can switch between different working modes through the internal diversion component 5. The three working modes improve the overall practicality of the device.

[0018] Working Principle: This embodiment provides a three-way valve structure for a urine bag. In use, the catheter and urine bag are connected to the inlet pipe 101 and the outlet pipe 103, respectively. When switching channels, rotating the knob 404 controls the lifting cylinder 401 via the screw 403. The lifting cylinder 401 rises and presses against the bottom opening 505 of the cone shroud 504, causing the bottom of the cone shroud 504 to unfold and fit against the inner wall of the valve pipe 1. At this time, the flow is switched to the diversion pipe 2. When the normal flow is open, urine slides down the inclined surface of the cone shroud 504 and is guided through the gap between the bottom of the cone shroud 504 and the inner wall of the valve pipe 1, allowing urine to drain from the outlet pipe 103. When sampling is required, remove the end cap 3 and connect the sampling bottle to the threaded port 203 of the diversion tube 2. Manually control the lifting cylinder 401 to rise and squeeze the bottom port 505 of the cone shroud 504, so that the bottom of it reduces the gap with the inner wall of the valve tube 1. When the drainage gap is reduced, the patient's urine accumulates in the lumbar cavity 503 during the urination drainage process. Some urine enters the sampling bottle through the diversion tube 2. When the sampling bottle is full, it does not affect normal urination and prevents urine from remaining in the pipeline for a long time due to failure to switch the passage in time. When flushing with medicine, the passage of the drain tube 103 can be completely closed so that the medicine can enter the bladder smoothly.
