TRANSURETHRAL CATHETER KIT, AND SYRINGE ASSEMBLY SUITABLE FOR USE IN CORRECTLY INFLATING A TRANSURETHRAL CATHETER

摘要

A transurethral catheter kit containing a balloon catheter and a syringe assembly adapted for inflation of the balloon, The syringe assembly includes a syringe and a nozzle incorporating a narrow bore proximal to a pressure relief valve. The narrow bore serves to resist the flow of fluid between the syringe and the balloon, thereby avoiding a rapid pressure increase in the balloon that can result in damage to tissues or premature activation of the pressure relief valve. Also provided is a method for correctly placing a transurethral balloon catheter in a patient using the kit.

主权项

1. A transurethral catheter kit comprising a catheter (2) and a syringe assembly (3), the catheter having a distal end (4) and a proximal end (5), an inflatable balloon having a balloon inflation pressure (6) disposed on the distal end, an inflation lumen having a proximal portion adapted to establish fluid communication with the syringe assembly (3) and a distal end in fluid communication with the balloon, and a drainage lumen adapted to drain fluid from the bladder during use, the syringe assembly having a syringe and a nozzle (11), the nozzle comprising a pressure relief valve (9) adapted to exhaust fluid from the syringe assembly during delivery of the fluid from the syringe into the balloon when the pressure in the fluid reaches a threshold pressure, characterized in that the nozzle additionally comprises a narrow bore (12) of 0.04 mm2 to 0.06 mm2 cross sectional area disposed in the nozzle proximally of the pressure relief valve.
