摘要：
The invention relates to a safety urinary catheter comprises a flexible, multi-lumen balloon catheter having a proximal catheter end, a distal catheter tip, a balloon (3642) having proximal and distal balloon ends and defining a balloon interior to be inflated with an inflation fluid, a hollow inflation lumen (3622), a hollow drain lumen (3612) parallel to the inflation lumen (3622), and a balloon deflation port. The balloon (3642) has proximal and distal balloon ends and defines a balloon interior to be inflated with an inflation fluid. The hollow inflation lumen (3622) extends through the catheter to the balloon interior at a balloon inflation port (3624) and towards the distal catheter tip, is shaped to convey the inflation fluid to and from the balloon interior, and has an anchor point (D) adjacent the proximal catheter end. The balloon deflation port (D) is at a stopper point distal of the inflation port (3624) and fluidically connects the inflation lumen (3622) to at least one of the drain lumen (3612) and an environment of the distal catheter tip. The catheter also comprises a stretch valve having a stopper (3636) disposed in the inflation lumen (3622) at a stopper point and shaped to block the inflation lumen at the stopper point when installed therewithin and prevent fluid from passing distally past the stopper point and a connector (3634) connected to the stopper (3636) and to the proximal catheter end at the anchor point, the anchor point and the stopper point defining a given distance. The connector (3634) has a length greater than the given distance, and, when the stopper (3636) is installed removably in the inflation lumen at the stopper point, the stopper prevents the inflation fluid from passing distally past the stopper point and from passing distally out from the inflation lumen or into the drain lumen, and, in a stretched state of the catheter when a length between the proximal catheter end and the proximal balloon end is elongated between approxi
