Abstract

Apparatus and method for suprapubic drainage of the urinary bladder comprises a small trocar for puncturing the bladder wall following which a flexible drainage tube is inserted through the lumen of the trocar and into the bladder. The trocar is then retracted from the patient and withdrawn from the tubing over the proximal end thereof. The proximal end of the tubing is then connected through a three way stopcock which is in turn connected to an additional piece of flexible tubing, the latter running to a portable suction-producing device which may be secured to the patient'"'"''"'"'s garment. A fully closed evacuating system is provided. The stopcock has an auxiliary passageway into which a hypodermic needle may be inserted to irrigate or flush the system, or to introduce medication into the bladder.

Claims

1. Apparatus for suprapubic drainage of the human urinary bladder comprising a drainage tube of flexible material and of relatively small transverse dimension and compatible with human tissue and arranged for insertion through a puncture in the abdomen and in the wall of the bladder, a self-contained, independently operable evacuator for ambulatory use comprising a container of flexible material, said container being resiliently compressible when subjected to manual pressure and upon release of said manual pressure being resiliently expansible to a normal expanded position, a conduit connecting said drainage tube to said container, an auxiliary fluid passageway arranged for connection to a receptacle, and valve means interconnecting said conduit, drainage tube and auxiliary passageway, said valve means having a first position interconnecting said conduit and drainage tube, a second position interconnecting said auxiliary passageway and said conduit, and a third position interconnecting said auxiliary passageway and said drainage tube, whereby fluid may be transmitted from the drainage tube into said container upon the expansion thereof, and fluid may be transmitted from the container into said receptacle, and treatment fluid may be transmitted from the receptacle into the drainage tube.

2. Apparatus for suprapubic drainage as set forth in claim 1 wherein said container is provided with an exhaust opening, and a closure valve for the exhaust opening.
