Urinary catheter

Abstract

The invention provides a urinary catheter including a bladder end closed top, a water bag, a urine drainage pipe, a flushing pipe, a water bag water injection pipe, a urinary catheter tail end and anannular flushing structure, wherein a micropore, a connector and a funnel-shaped connection port are disposed on the side wall of the annular flushing structure. Pipes on the urinary catheter are notcommunicated with each other and are provided with outlets and inlets respectively. The annular flushing structure divides the urinary catheter into catheter bodies with two diameters, so that a gap is formed between the urinary catheter and the urethra, drainage can be performed effectively, and urethra postoperation secretions can be flushed. The side wall of the annular flushing structure is provided with the micropore, wherein the included angle between the micropore and the axis parallel to the urinary catheter is smaller than 90 degrees, and the further damage of the urethra suture can be reduced. The connector and the funnel-shaped connection port are of a detachable structure. When flushing is not required, the connector and the funnel-shaped connection port can be dismantled, to alleviate the burden on a patient; connection ports of each pipe are in dislocation layout, and misoperation is reduced.

Description

technical field [0001] The invention relates to the field of medical auxiliary devices, in particular to a urinary catheter for drainage and flushing of secretions after urethral operations. Background technique [0002] Urinary catheterization is one of the commonly used medical procedures in clinic, and it needs to be used in many cases. Urinary catheters are often used to collect urine and drain urine, especially in urology after urethral surgery, and are widely used. After urethral surgery, patients often need to keep the catheter for about 3 weeks, and during this period is also the stage when secretions from the urethral wall accumulate after surgery. Invention patent (CN 103263719 A) discloses a urethral flushing catheter, which has a drainage cavity inside the structure and a balloon on the catheter. Flow, if the secretion is more viscous, it is easier to stagnate and accumulate. The enzymes in the secretion will further break down the outer tissue and cause damag...

AI Technical Summary

Problems solved by technology

If the secretion accumulates too much, the pressure between the catheter and the urethra will increase, which may lead to oppressive occlusion of the catheter, thereby causing urinary retention, with serious consequences

Although the above-mentioned invention is provided with flushing microholes on the tube wall in the middle part of the urinary catheter, flushing is performed perpendicular to the urethral tube wall during flushing. Douching cannot control the outflow direction of urethral secretions, but may cause secretions to accumulate deep in the urethra
