Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a disposable ureteral catheter. Background Technology
[0002] A urinary catheter is a tube made of natural rubber, silicone rubber, or polyvinyl chloride (PVC) that can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a balloon near the head of the catheter to keep it in the bladder and prevent it from falling out. The tail end is connected to a urine bag to collect urine.
[0003] Existing ureteral catheters are usually of a fixed length and cannot be adjusted. This often leads to the catheter being accidentally pulled out due to its excessive length. To address this issue, we propose a disposable ureteral catheter. Utility Model Content
[0004] The purpose of this invention is to provide a disposable ureteral catheter to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a disposable ureteral catheter, comprising:
[0006] A first conduit and a second conduit. The first conduit has a connector at its end, and a connecting seat is provided on the connector. The second conduit is fixedly bonded to the connecting seat and extends into the inner cavity of the first conduit through the connector and the connecting seat. A sealing ring is installed inside the connector and is slidably connected to the outer wall of the second conduit. An installation block is fixedly bonded to the connector, a fixing rod is fixedly bonded to the installation block, and a clamp is fixedly bonded to the fixing rod. Adhesive tape is provided on the first conduit.
[0007] Preferably, a retaining ring is fixedly bonded to one end of the second catheter located in the inner lumen of the first catheter.
[0008] Preferably, the plug-in socket and the connector are integrally formed.
[0009] Preferably, both the first catheter and the second catheter are made of medical-grade polyurethane material.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] In use, the second catheter can slide within the first catheter to adjust its overall length, allowing for adjustment of the ureteral catheter length as needed. This avoids the problem of the ureteral catheter becoming loose due to accidental dragging caused by excessive length, thus improving the convenience of using the ureteral catheter. After adjustment, the provided tape can be adhered to the second catheter located at the insertion seat, and the insertion seat can be fixed by clamping it onto the tape, ensuring the stability of the first and second catheters after adjustment.

[0016] 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.
[0017] Please see Figure 1-3 This utility model provides a technical solution: a disposable ureteral catheter, comprising:
[0018] A first conduit 1 and a second conduit 2 are provided. A connector 3 is provided at the end of the first conduit 1. A connecting seat 4 is provided on the connector 3. The second conduit 2 is fixedly bonded to the connecting seat 4. The second conduit 2 passes through the connector 3 and the connecting seat 4 and extends into the inner cavity of the first conduit 1. A sealing ring 5 is installed in the connector 3. The sealing ring 5 is slidably connected to the outer wall of the second conduit 2. An installation block 6 is fixedly bonded to the connector 3. A fixing rod 7 is fixedly bonded to the installation block 6. A clip 8 is fixedly bonded to the fixing rod 7. Adhesive tape 9 is provided on the first conduit 1.
[0019] A retaining ring 10 is fixedly bonded to one end of the second conduit 2 located in the inner cavity of the first conduit 1. The retaining ring 10 can prevent the second conduit 2 from slipping out and detaching from the first conduit 1.
[0020] The plug-in socket 3 and the connector 4 are integrally formed.
[0021] Both the first catheter 1 and the second catheter 2 are made of medical polyurethane material, which has strong anti-aging properties and good biocompatibility, thus improving the effectiveness of the catheters.
[0022] Working principle: In use, the second catheter 2 can slide within the first catheter 1 to adjust the overall length, allowing the length of the ureteral catheter to be adjusted as needed. This avoids the problem of the ureteral catheter becoming loose due to accidental dragging caused by excessive length. After adjustment, the provided tape 9 can be adhered to the second catheter 2 located at the insertion seat 3, and the insertion seat 3 is fixed by clamping it with the tape 9 using the provided clip 8, ensuring the stability of the first catheter 1 and the second catheter 2 after adjustment.
