US 2009/0024111 A1 · Urethral catheter assembly for combining catheterization with injection of therapeutic liquid into the urethral channel

Abstract

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.

Dependent claims

A urethral catheter assembly for urethral catheterization comprising:

a hollow casing that has a distal end, a bottom portion with an opening at said distal end, a proximal end, and an interior;
a catheter moveably installed in the hollow casing and having a distal end and a proximal end;
an anti-infectious cap attached to the distal end of the hollow casing and intended for guiding the catheter into the urethra without contact with the urethral wall in the vicinity of the urethral meatus, said anti-infective cap having a slit for passing the catheter;
a therapeutic liquid that fills the interior of the hollow casing;
and
a means for injecting therapeutic liquid into the urethra simultaneously with urethral catheterization;
the catheter assembly having a storage condition in which the catheter is stored inside the hollow casing and a catheterization condition in which the catheter projects from the distal end of the hollow casing.

A method of urethral catheterization by means of a catheter assembly simultaneously with introduction into the urethra of a therapeutic liquid, said method:

providing a catheter assembly in the form of a tubular body filled with a therapeutic liquid and having a urinary catheter with a piston portion slidingly installed in said tubular body;
providing the tubular body with an anti-infectious cap;
inserting the anti-infectious cap into the patient's urethra;
and
performing catheterization by inserting the catheter into the urethra through said anti-infections cap and simultaneously injecting therapeutic liquid into the urethra through said anti-infectious cap by displacing the therapeutic liquid from the tubular body by means of the piston portion of the catheter.
