Abstract

The invention relates to an indwelling catheter which comprises an outer tube and an inner tube, and the front ends of the inner tube and the outer tube are relatively and fixedly kept in a bladder through an in-vivo fixing device; the in-vivo fixing device comprises an umbrella-shaped part capable of being unfolded and folded, and the umbrella-shaped part comprises elastic strips and connecting films; the rear ends of the elastic strips are fixedly connected with the front end of the inner tube to form a framework of the umbrella-shaped part; and the connecting films wrap the elastic strips and are connected between the adjacent elastic strips to form an umbrella cover of the umbrella-shaped part. During use, the front end of the inner tube is fixedly connected with the umbrella-shaped part to form a funnel structure, urine in the bladder is sequentially discharged through the funnel, and the urine remaining at the bottom of the bladder seeps from gaps between the outer tube and the inner tube, forms a siphonic effect and is quickly discharged; and a unique fixing structure is adopted to ensure that the catheter is stably in place, meanwhile, the thoroughness of urination is improved, urine residues are reduced, and the probability of bacterial infection is effectively reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular, it is a urinary catheter. Background technique [0002] After clinical treatment of cardiovascular and cerebrovascular diseases, spinal cord vascular diseases, or after treatment such as coma, paraplegia, and surgery, patients often have urination obstacles. When the catheter needs to be used for a long time, the built-in or indwelling catheter is a better choice; one end of the indwelling catheter extends into the bladder, and the other end protrudes from the urethra; the end in the bladder passes through An inflatable balloon placed in the bladder is held in place and urine is passed through the urinary catheter. [0003] However, there are many defects in the current indwelling catheter: because the front end is provided with an inflatable air bag, the size of the front end of the catheter is relatively large, which causes strong discomfort when inserting and pulling out the ca...
