Abstract

The invention relates to a catheter capable of adjusting the size of a drainage opening. The catheter comprises a drainage tube, a drainage cap and a control guide wire; the drainage tube is provided with an expansion air bag, an inflation tube and the drainage opening; the drainage cap is detachably connected with the top part of the drainage tube, and the control guide wire is connected with the drainage cap; the bottom part of the side edge of the drainage cap is provided with second connecting parts; the second connecting parts are two or four convex column structures; correspondingly, the drainage tube is provided with first connecting parts; the first connecting parts are cylindrical grooves fitting with the convex column structures; the center of the drainage cap is provided with the control guide wire; and the drainage cap can be pulled out along the drainage tube. The catheter has the advantages that a blockage can be guided out in time when the catheter is blocked, and the diameter of the catheter does not need to be changed; operation is easy, use is flexible, and the size of the drainage opening can be adjusted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheter with an adjustable drainage port. Background technique [0002] Urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride, which can be inserted into the bladder through the urethra to drain urine or blood clots. After the catheter is inserted into the bladder, the drainage tube is connected to a urine bag to collect urine or blood clots. [0003] At present, the front end of the commonly used urinary catheter is round, and there are two side holes beside the catheter for drainage of urine, but for some larger blood clots, stones or human tissue fragments are difficult to pass through, so often the side needs to be replaced. Larger and thicker urinary catheters will virtually increase the cost of the patient and aggravate the pain of the patient; especially for some patients with urethral strictures, there is still a problem that...
