Urethra air bag capable of conducting secondary drainage

Abstract

The invention relates to the technical field of urethra air bags, in particular to a urethra air bag capable of conducting secondary drainage. The device comprises a catheter body, wherein a catheterization opening is formed in one side of the interior of the catheter body, and a fixed air bag is arranged on one side of the exterior of the catheter body; and a secondary drainage mechanism that comprises guide valves, wherein the guide valves are arranged on the two sides of the outer portion of the catheter body, and first drainage openings are formed in the two sides of the outer portion of the catheter body. According to the urethral catheter, after the urethral catheter body is placed, the guiding valves on the two sides can be attached to the exterior of the urethra of a patient through extrusion of the distraction air bag, so that leaked urine is subjected to secondary drainage and cannot directly flow out of the urethra, and the patient is effectively protected; thus, in the urethral catheterization process, the device is not prone to liquid leakage and the like, guiding is more thorough, and the practicability and the protection performance of the device are improved.

Description

technical field [0001] The invention relates to the technical field of urethral balloons, in particular to a urethral balloon capable of secondary drainage. Background technique [0002] Catheterization is the insertion of a catheter through the urethra into the bladder to drain urine. The purpose is to relieve urinary retention, take uncontaminated urine samples for examination, measure residual urine, measure bladder cold and heat sensation, volume, pressure, inject contrast medium or drugs to help diagnosis or treatment, etc. The operator stands on the right side of the patient, wears sterile gloves, sterilizes the perineum and urethra with sterile water or benzalkonium bromide, dips the front end of the catheter with sterile lubricating oil, and inserts the catheter into the bladder until there is urine in the catheter. A common instrument used during surgery is a urinary catheter, a tube that is inserted from the urethra into the bladder to drain urine. It is a tube m...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a urethral airbag that can be used for secondary drainage, so as to solve the problem that the main body of the catheter in the above-mentioned background technology is often not equipped with other protective structures outside when guiding, which may cause urine to flow along with the catheter. The external flow of the catheter leads to side leakage, etc., and the main body of the catheter usually needs to be left in the patient's body during use. When leakage occurs, it is not easy to detect, and the leaked urine is easy to adhere to On the patient's clothes and hospital bed, it is troublesome and inconvenient for subsequent cleaning
