METHOD AND APPARATUS FOR PLACEMENT OF A SUPRAPUBIC CATHETER

摘要

Abstract of the DisclosureA suprapubic catheter is inserted into a bladder in a safe,efficient and simple manner by first inserting a hollow, curved and rigidtubing member transurethrally into a bladder. The tubing member has acatheter therewithin onto which a cutting point is attached, and is con-structed in such a manner as to permit the cutting point to, when pushedthrough the distal end thereof, pierce the anterior wall of the bladderafter it has been externally palpated for placement. The cutting point, thenemerging from the bladder, can be grasped externally and the catheter can bepulled through the tubing member and into the bladder to a premarked pointthereon and may be separated from the main body of the catheter and connectionmade to a conventional drainage and collection assembly. The tubing memberis then withdrawn backwardly leaving the catheter tube safely within thebladder in the proper position. A stylet may be employed to remove thecatheter when drainage is to be terminated.
