Description

Technical Field

[0001] This utility model belongs to the field of silicone urinary catheter technology, specifically relating to a silicone urinary catheter that can be used to collect urine specimens. Background Technology

[0002] In clinical diagnosis and treatment, urine specimen collection is an important means of diagnosing urinary system diseases and monitoring changes in the condition. As the core device for long-term indwelling patients' urine drainage, the compatibility of silicone urinary catheters with urine specimen collection procedures directly affects the efficiency of diagnosis and treatment and patient safety.

[0003] When using existing silicone urinary catheters, if it is necessary to sample and test the medication in the urine bag, the catheter must be separated from the urine bag, and then urine must be collected through the end of the catheter or the interface of the drainage bag. This operation not only compromises the airtightness of the urinary catheter system, allowing external bacteria to enter and significantly increasing the risk of urinary tract infection, but also easily causes urine leakage when disconnected, contaminating the medical environment and operators, which is not conducive to practical use. Utility Model Content

[0004] The purpose of this invention is to provide a silicone urinary catheter for puncturing and collecting urine specimens, which can complete the puncture and collection of urine without disconnecting the catheter from the urine bag, thus avoiding the problem of bacterial invasion caused by disconnection in traditional methods.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A silicone urine catheter for puncturing and collecting urine specimens includes a catheter body, a sleeve fitted on the side wall of the catheter body, a receiving tube fixedly connected to the side wall of the sleeve, a puncture guide assembly disposed inside the receiving tube, a connecting tube fixedly connected to the side wall of the receiving tube, a sample container assembled at the bottom of the connecting tube, a connecting tube fixedly connected to the top of the sample container, and a sealing assembly disposed inside the connecting tube.

[0007] Furthermore, the puncture and drainage assembly includes a puncture tube disposed inside the receiving tube. The end of the puncture tube near the main body of the urinary catheter is open, and the open end of the puncture tube is pointed. A movable rod is fixedly connected to the end face of the puncture tube. The other end of the movable rod passes through the receiving tube and is fixedly connected to a pressure plate. The movable rod is movably connected to the receiving tube. Drainage holes are respectively opened on the side walls of the puncture tube and the receiving tube.

[0008] Furthermore, a protrusion is fixedly connected to the end face of the puncture tube opening.

[0009] Furthermore, the connecting pipe and the connecting tube are connected by threads.

[0010] Furthermore, the sealing assembly includes a flow guide ring fixedly connected to the inner wall of the connecting pipe, a sealing block is provided on the lower side of the flow guide ring, a vertical rod is fixedly connected to the top surface of the sealing block, a limit plate is fixedly connected to the inner wall of the connecting pipe, the vertical rod corresponds to the limit plate, and a spring is fixedly connected between the flow guide ring and the sealing block.

[0011] Furthermore, both the guide ring and the blocking block have inclined surfaces on their sidewalls, and the inclined surface of the blocking block abuts against the inclined surface of the guide ring.

[0012] Furthermore, a guide block is fixedly connected to the inner wall of the urinary catheter body, and the side wall of the guide block is inclined.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a silicone urine catheter for puncturing and collecting urine specimens. Through the cooperation of the sleeve, storage tube, puncture and drainage component and sample container, medical staff only need to press the pressure plate to push the puncture tube to complete the puncture. The operation is convenient and labor-saving. Moreover, the connecting tube on the side wall of the storage tube can be directly connected to the sample container. Urine flows directly into the sample container through the puncture tube, drainage hole and connecting tube, without the need for additional specimen transfer. This avoids the risk of specimen spillage and confusion and shortens the urine collection operation time. Attached Figure Description

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-5 As shown, a silicone urine catheter for puncturing and collecting urine specimens includes a urine catheter body 1. A sleeve 2 is fitted onto the side wall of the urine catheter body 1. The sleeve 2 is made of elastic rubber and can be elastically fitted onto the urine catheter body 1. The position of the sleeve 2 on the urine catheter body 1 can also be adjusted according to sampling requirements. A receiving tube 3 is fixedly connected to the side wall of the sleeve 2. A puncture guide component is provided inside the receiving tube 3. A connecting tube 4 is fixedly connected to the side wall of the receiving tube 3. A sample container 10 is assembled at the bottom of the connecting tube 4. A connecting tube 11 is fixedly connected to the top of the sample container 10. A sealing component is provided inside the connecting tube 11.

[0024] like Figure 2 and Figure 3 As shown, the puncture drainage assembly includes a puncture tube 5 disposed inside the receiving tube 3. The end of the puncture tube 5 closest to the urinary catheter body 1 is open, and the open end of the puncture tube 5 is pointed. A movable rod 6 is fixedly connected to the end face of the puncture tube 5. The other end of the movable rod 6 passes through the receiving tube 3 and is fixedly connected to a pressure plate 7. The movable rod 6 is movably connected to the receiving tube 3. Drainage holes 8 are respectively opened on the side walls of the puncture tube 5 and the receiving tube 3. A protrusion 9 is fixedly connected to the open end face of the puncture tube 5.

[0025] The puncture tube 5 is preferably made of 304 stainless steel or 316 stainless steel, which makes it easy to puncture the main body 1 of the urinary catheter when the tip is subjected to force. In addition, the puncture tube 5 and the receiving tube 3 adopt a tight interference fit, which can increase the sealing between the two and prevent urine from leaking from the drainage hole 8 and the receiving tube 3.

[0026] In some embodiments, two sealing rings can be installed on the outer wall of the puncture tube 5 on both sides of the guide hole 8. The sealing rings abut against the inner wall of the receiving tube 3 to further enhance the sealing performance. In the initial state, the guide holes 8 on both sides are in an interleaved state.

[0027] Specifically, after the urinary catheter body 1 is punctured, in order to avoid the puncture site of the urinary catheter body 1 from blocking the puncture tube 5, a protrusion 9 is provided to push the punctured urinary catheter body 1 upward, so that the urine can smoothly enter the puncture tube 5. At the same time, in conjunction with the inclined surface of the guide block 17, it is easy to guide the urine into the puncture tube 5, further improving the sampling efficiency.

[0028] like Figure 5 As shown, the connecting pipe 4 and the connecting pipe 11 are connected by threads. The threaded connection not only provides a tight seal but also facilitates installation and disassembly, effectively reducing sampling time.

[0029] like Figure 5 As shown, the sealing assembly includes a flow guide ring 12 fixedly connected to the inner wall of the connecting pipe 11, a sealing block 13 is provided on the lower side of the flow guide ring 12, a vertical rod 14 is fixedly connected to the top surface of the sealing block 13, a limiting plate 15 is fixedly connected to the inner wall of the connecting pipe 4, the vertical rod 14 corresponds to the limiting plate 15, and a spring 16 is fixedly connected between the flow guide ring 12 and the sealing block 13.

[0030] Both the guide ring 12 and the blocking block 13 have inclined surfaces on their sidewalls, and the inclined surface of the blocking block 13 abuts against the inclined surface of the guide ring 12.

[0031] The sealing assembly inside the connecting tube 11, through the cooperation of the guide ring 12, the sealing block 13, and the spring 16, ensures that when no urine is being collected, the spring 16 pushes the sealing block 13 to fit tightly against the guide ring 12, achieving airtight storage of the sample container 10 and preventing specimen leakage or contamination. When urine is being collected, the urine pressure pushes the sealing block 13 to compress the spring 16, allowing urine to flow smoothly into the sample container 10. After urine collection stops, the spring 16 resets and re-seals, ensuring both the smoothness of the urine collection process and the integrity of the specimen during storage and transportation, thereby improving the accuracy of the test results.

[0032] like Figure 2 As shown, a guide block 17 is fixedly connected to the inner wall of the urinary catheter body 1, and the side wall of the guide block 17 is inclined. The inclined surfaces of the guide ring 12 and the sealing block 13 can increase the contact area between them and improve the sealing effect.

[0033] The working principle of this utility model is as follows: When urine sampling is required, the sample container 10 is first screwed into the connecting tube 4 through the connecting tube 11. At the same time as screwing in, the vertical rod 14 abuts against the limiting plate 15. As the sample container 10 moves upward, the vertical rod 14 pushes down to open the sealing block 13. At the same time, the spring 16 is stretched, so that the connecting tube 4 and the sample container 10 are in a connected state. Then, the pressure plate 7 is pressed. The pressure plate 7 drives the puncture tube 5 to puncture the urine catheter body 1 through the movable rod 6, puncturing the puncture tube 5. At the same time, the protrusion 9 can be used to push the punctured urine catheter body 1 upward. When the puncture tube 5 is inserted into the urine catheter body 1, the guide block 17 is located in the tip of the puncture tube 5. At the same time, the two guide holes 8 are in a connected state. The urine enters the puncture tube 5 through the guide block 17, and then enters the sample container 10 for preservation through the guide hole 8 and the connecting tube 4.

[0034] After sampling is completed, pull the pressure plate 7 to reset the puncture tube 5. The two guide holes 8 are in an alternating state. Some urine will enter the puncture tube 5, but because the puncture tube 5 is tightly pressed against the inner wall of the receiving tube 3, it can play a sealing role and the urine will not leak from the guide hole 8. Then, flip the sample container 10 to remove it. At the same time, the spring 16 rebounds and drives the sealing block 13 to stick to the guide ring 12 to seal the sample container 10 and prevent the sample from being contaminated.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
