Urethral catheter assembly for combining catheterization with injection of therapeutic liquid into the urethral channel

摘要

A compact ready-to-use urethral catheter assembly suitable for intermittent self-catheterization that comprises a tubular body filled with a therapeutic liquid and having a urinary catheter with a piston portion slidingly installed into the tubular body so that catheterization is accompanied by automatic injection of the therapeutic liquid into the urethra by means of the piston through a gap formed during catheterization between the outer surface of the catheter and the inner walls of the antiseptic cap which is used as a sterile guide for insertion of the catheter without contact with the initial part of the urethra which may be a harbor of infection. The assembly is provided with built-in means for cleaning the urethral meatus before catheterization.
