Methods and devices for aseptic irrigation, urine sampling, and flow control of urine from a catheterized bladder

摘要

A urinary catheter connector system having a housing; a catheter connector port supported by the housing and configured to attach to a urinary catheter; a urine exit port supported by the housing and configured to connect to a urine collection device; an irrigation port supported by the housing and configured to receive an irrigation syringe; a channel in the housing fluidly connecting the catheter connector port, the urine exit port and the irrigation port; and a valve supported by the housing and adapted to cooperate with the irrigation syringe to shut off flow of fluid and air to the urine exit port when the irrigation syringe is inserted and allow for flow of fluid and air to the urine exit port when the irrigation syringe is removed. The invention also includes methods of using the system.

1. A urinary catheter connector system comprising:
a housing; a catheter connector port supported by the housing and configured to attach to a urinary catheter; a urine exit port supported by the housing and configured to connect to a urine collection device; an irrigation port supported by the housing and configured to receive an irrigation syringe; a channel in the housing fluidly connecting the catheter connector port, the urine exit port and the irrigation port; an internal valve supported by the housing and adapted to cooperate with the irrigation syringe to shut off flow of fluid and air to the urine exit port when the irrigation syringe is inserted and allow for flow of fluid and air to the urine exit port when the irrigation syringe is removed; and a valve control mechanism comprising a compliant balloon adapted to be inflated to close the internal valve, wherein the valve control mechanism further comprises a compressible fluid-filled actuation chamber, first and second passages connecting the actuation chamber with the interior of the balloon and a one-way valve disposed in the first passage to permit fluid flow from the actuation chamber into the balloon and block fluid flow from the balloon into the actuation chamber.
