HYDRODYNAMICALLY BALANCED DRAINAGE SYSTEM

Medical fluid flow control system comprising a pressure-sensitive unidirectional magnetic valve connected to a urinary catheter on the entry end and exiting to a drainage line and fluid collection bag. This unique valve opens at a very low pressure and, even when the opening pressure is gone, it remains open until no more fluid flows through it and down the tubing, due to the change in hydrodynamic pressure as the bladder drainage is completed
