Abstract

Valves and medication delivery systems including valves are described herein. A valve includes a valve body and a valve element. The valve body defines a first flow path, a second flow path, and a catheter flow path. The valve element is disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, and is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position.

First claim

What is claimed is:

1. A standalone valve, comprising:
a valve body defining a first flow path, a second flow path, and a catheter flow path; and
a valve element disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position and the valve element is actuated to the dispensing position by pressurizing the first flow path and the second flow path to a first pressure,
wherein the standalone valve is configured to be coupled to a first end of a flexible tubing having a syringe coupled to a second end of the flexible tubing.

2. A medication delivery system, comprising:
a flexible tubing;
a syringe coupled to a first end of the flexible tubing, comprising:
a syringe body defining a syringe cavity;
a first plunger disposed within the syringe cavity and defining a first chamber in the syringe cavity; and
a second plunger disposed within the syringe cavity, the second plunger defining a second chamber in the syringe cavity; and

a valve coupled to a second end of the flexible tubing, comprising:
a valve body defining a first valve flow path in fluid communication with the first chamber, a second valve flow path in fluid communication with the second chamber, and a catheter flow path in fluid communication with a catheter; and
a valve element disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first chamber and the second chamber in a priming position, and is configured to permit fluid communication between the first chamber and the catheter flow path in a dispensing position.

3. The medication delivery system of claim 2 , wherein the flexible tubing is a dual lumen tubing defining a first tubing flow path and a second tubing flow path, wherein the first tubing flow path permits fluid communication between the first chamber and the first valve flow path and the second tubing flow path permits fluid communication between the second chamber and the second valve flow path.

4. The medication delivery system of claim 3 , wherein the flexible tubing is longer than the catheter.

5. The medication delivery system of claim 2 , wherein the valve element is actuated to the dispensing position by pressurizing the first chamber and the second chamber to a first pressure.

6. The medication delivery system of claim 2 , wherein the valve element is actuated to the dispensing position by actuating a portion of the valve body.

7. The medication delivery system of claim 2 , wherein the valve element is actuated to the dispensing position by receiving a pressure impulse from the first chamber.

8. The medication delivery system of claim 2 , wherein the valve element is actuated to the dispensing position by receiving a pressure impulse from the second chamber.

9. A standalone valve, comprising:
a valve body defining a first flow path, a second flow path, and a catheter flow path; and
a valve element disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position, and the valve element is actuated to the dispensing position by receiving a pressure impulse in the first flow path,
wherein the standalone valve is configured to be coupled to a first end of a flexible tubing having a syringe coupled to a second end of the flexible tubing.

10. A standalone valve, comprising:
a valve body defining a first flow path, a second flow path, and a catheter flow path; and
a valve element disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position, and the valve element is actuated to the dispensing position by receiving a pressure impulse in the second flow path,
wherein the standalone valve is configured to be coupled to a first end of a flexible tubing having a syringe coupled to a second end of the flexible tubing.
