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.
Claims20
A 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, and is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position.
A medication delivery system, comprising:
- a syringe, 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;
- a second plunger disposed within the syringe cavity, the second plunger defining a second chamber in the syringe cavity;
- and
- a valve, 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.
A method to deliver medication, the method comprising:
- introducing saline into a medication flow path;
- and
- directing saline from the medication flow path to a return flow path via a valve element;
- and
- introducing medication into the medication flow path;
- actuating the valve element to permit fluid communication between the medication flow path and a catheter;
- and
- directing medication from the medication flow path into the catheter.
