METHODS AND DEVICES FOR ASEPTIC IRRIGATION, URINE SAMPLING, AND FLOW CONTROL OF URINE FOR A CATHETERIZED BLADDER

摘要

A connector system includes a catheter connector port to attach to a urinary catheter, a urine exit port to connect to a urine collection device, an irrigation port to receive an irrigation syringe, and an internal valve. The irrigation port includes a pliable membrane that has a self-sealing opening to allow a tip of the syringe to extend therethrough. The internal valve cooperates with the syringe to shut off flow of fluid to the urine exit port when the syringe is inserted and allow for flow of fluid to the urine exit port when the syringe is removed. A distance between a proximal surface of the membrane and a distal end of the internal valve is such that the tip of the syringe can extend from a proximal end of the self-sealing opening to the distal end of the internal valve.

主权项

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, wherein the irrigation port includes a pliable membrane extending thereover, the pliable membrane having a self-sealing opening therein configured to allow a tip of the irrigation syringe to extend therethrough; a channel in the housing fluidly connecting the catheter connector port, the urine exit port and the irrigation port; and 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; wherein a distance between a proximal surface of the membrane and a distal end of the internal valve is selected such that the tip of the irrigation syringe can extend from a proximal end of the self-sealing opening to the distal end of the internal valve when the irrigation syringe is inserted into the irrigation port.
