Abstract

The urinary catheter system includes a urinary catheter, a connector and a medical implement which is readily attached to or removed from the connector. When a medical implement such as a collection appliance is attached to the connector, fluid such as urine can flow from the patent and into the collection appliance. Alternatively, when a syringe is attached to the connector, the catheter system may be irrigated to remove debris and other foreign matter, or the syringe may be used to provide medication to the patient. The system is preferably a closed system in which the connector includes a resealable valve which prevents the flow of fluid through the connector if a medical implement is not attached.

Claims

1. A urinary catheter system, comprising:

a catheter set, comprising;

a connector including a wall structure defining an internal cavity, said connector having a first end configured to be placed in fluid communication with a urinary catheter, said connector having a second end configured to mate with an adapter or a syringe; and

a resealable valve located in said internal cavity movable between an open position and a closed position, said resealable valve in said closed position being configured to prevent fluid flow in a direction from said first end to said second end and in said closed position being adapted to prevent fluid flow in a direction from said second end to said first end, said resealable valve being adapted to be moved into said open position by insertion of an adapter into the second end of said connector, said resealable valve in said open position being adapted to allow fluid flow from the catheter into an adapter, said resealable valve further being adapted to be moved into said open position by insertion of a syringe into the second end of said connector, said resealable valve in said open position being adapted to allow fluid flow from a syringe into the catheter;

a collection set adapted to be removably coupled to the catheter set, the collection set comprising;

an adapter configured to mate with the connector of the catheter set and configured to permit fluid flow through said adapter; and

a one-way valve proximate the adapter;

wherein said one-way valve is configured to permit fluid flow from the catheter, through the adapter and subsequently through said one-way valve, and to impede fluid flow through said one-way valve to the adapter.

2. The urinary catheter system of claim 1, wherein said resealable valve further comprises a seal and a spike, and said seal adapted to be compressibly moved in a direction from said second end to said first end.

3. The urinary catheter system of claim 1 further comprising a syringe adapted to compressibly move said seal.

4. The urinary catheter system of claim 1 further comprising:

a collection appliance to receive fluid from the catheter.

5. The urinary catheter system of claim 1 wherein the one-way valve is integral with the adapter.
