Description

Technical Field

[0001] This utility model relates to the field of urinary catheter technology, and in particular to a urinary catheter. Background Technology

[0002] A urinary catheter is a widely used medical device in clinical treatment, typically used to assist patients in urination or for urine drainage, especially when patients are unable to urinate independently or require long-term indwelling catheterization. Catheters are usually made of materials such as natural rubber, silicone rubber, or polyvinyl chloride, which offer good flexibility and biocompatibility, ensuring comfort and safety during long-term use. The basic design and functional requirements of a urinary catheter include catheterization, drainage, and fixation, aiming to provide efficient and safe urine drainage while ensuring patient comfort.

[0003] Existing urinary catheters typically consist of a flexible tube, a catheter port, an inflator valve, a balloon, and an outlet tube. The catheter port is inserted into the patient's urethra, the tube serves to guide urine, and the balloon is designed to secure the catheter within the bladder and prevent displacement. The inflator valve is used to inject saline or other fluids to inflate the balloon within the bladder, thus securing the catheter. The outlet tube is responsible for draining the flowing urine into a connected urine bag, completing the urination process.

[0004] Traditional urinary catheters typically secure the outlet tube by directly fitting it onto the tubing of the urine bag using the material's elasticity. However, when the outlet tube and urine bag are subjected to external force, they are prone to separation, causing accidental spillage of urine flowing inside the catheter. Furthermore, the current design is inconvenient for urine sampling when patients with indwelling catheters need to collect urine for testing.

[0005] Therefore, we propose a urinary catheter. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a urinary catheter.

The rear ends of each elastic plate are respectively fixedly connected to the front wall of the pressure block, and a rubber pad is fixedly connected to the side of each pressure block near the liquid outlet pipe body.

[0009] As a preferred embodiment of this utility model, the front end of the movable ring is rotatably connected to the rear end of the threaded ring, and the tapered extrusion ring is fixedly connected to the rear end wall of the movable ring.

[0011] As a preferred embodiment of this utility model, a shunt tube is fixedly connected to the urinary catheter body, the shunt tube is connected to the urinary catheter body, and a sealing ball is located at the connection between the shunt tube and the urinary catheter body, the diameter of the sealing ball being the same as the diameter of the urinary catheter body.

[0012] As a preferred technical solution of this utility model, the sealing ball is provided with a drainage hole one and a drainage hole two, which are connected and have a T-shaped structure. When the sealing ball enters the inside of the catheter body, the drainage hole one is aligned with the direction of the catheter body.

[0014] This invention provides a urinary catheter. It has the following beneficial effects:

[0015] 1. When using this type of urinary catheter, the following steps can be taken to fix the outlet tube body of the catheter body to the urine bag tube: First, insert the rear half of the outlet tube body into the urine bag tube. Then, by rotating the threaded ring, it moves backward on the threaded tube. As the threaded ring moves backward, the moving ring and the conical compression ring also move backward synchronously. Multiple pressure blocks contract inward under the compression of the conical compression ring, tightly pressing the catheter body onto the urine bag tube. In this way, when subjected to external force, the outlet tube body is not easy to detach from the urine bag tube, avoiding accidental urine spillage.

[0016] 2. When using this type of urinary catheter, if a urine test is required, simply rotate the rotating plate, which will cause the rotating rod to rotate, thus rotating the sealing ball 90 degrees clockwise. At this time, the first drainage hole inside the sealing ball connects with the shunt tube, and the second drainage hole connects with the upper part of the catheter body. Through this operation, urine can be smoothly drained into the shunt tube, facilitating urine collection and testing. This operation is simple and convenient, minimizing contamination to patients, the surrounding environment, and medical staff, while also improving the practicality of the equipment.
