Abstract

Syringe control assemblies are described herein. A syringe control assembly includes an assembly body, a first syringe, a second syringe, and a pump assembly. The first and second syringes are releasably coupled to a syringe mounting rack of the assembly body. The pump assembly includes a first pump unit and a second pump unit. Each pump unit is in fluid communication with each respective syringe. In a priming configuration, the first pump unit is configured to draw fluid flow from the first syringe cavity and the second pump unit is configured to pump fluid flow into the second syringe cavity.

First claim

What is claimed is:

1. A syringe control assembly, comprising:
an assembly body comprising a syringe mounting rack;
a first syringe releasably coupled to the syringe mounting rack, the first syringe comprising a first syringe body defining a first syringe cavity and a first syringe port, wherein the first syringe port is in fluid communication with the first syringe cavity;
a second syringe releasably coupled to the syringe mounting rack, the second syringe comprising a second syringe body defining a second syringe cavity and a second syringe port, wherein the second syringe port is in fluid communication with the second syringe cavity; and
a pump assembly coupled to the assembly body, the pump assembly comprising:
a first pump unit in fluid communication with the first syringe port via a first pump tubing, wherein the first pump unit comprises:
a rotary pump comprising a pump cavity in fluid communication with the first syringe port; and
a motor coupled to the pump, wherein the motor is configured to rotate a portion of the rotary pump; and

a second pump unit in fluid communication with the second syringe port via a second pump tubing, wherein in a priming configuration the first syringe cavity and the second syringe cavity are in fluid communication and the first pump unit is configured to draw fluid flow from the first syringe cavity toward a catheter and the second pump unit is configured to pump fluid flow from the first syringe cavity toward the second syringe cavity, and

a valve, wherein a first portion of the valve is directly coupled to a terminal end of a delivery flow path from the first syringe cavity and a terminal end of a return flow path to the second syringe cavity, and a second portion of the valve is directly coupled to a terminal end of the catheter, wherein the valve is configured to prevent fluid flow from the first syringe cavity from entering the catheter and to direct fluid flow from the first syringe cavity through the valve and toward the second syringe cavity in the priming configuration.

2. The syringe control assembly of claim 1 , further comprising:
a fluid manifold comprising a manifold inlet and a manifold outlet, wherein the manifold inlet and the manifold outlet are in fluid communication and the manifold outlet is in fluid communication with the first pump unit; and
a third syringe releasably coupled to the syringe mounting rack, the third syringe comprising a third syringe body defining a third syringe cavity and a third syringe port, wherein the third syringe port is in fluid communication with the third syringe cavity,
wherein the pump assembly further comprises:
a third pump unit in fluid communication with the third syringe port via a third pump tubing, wherein in a pushing configuration the third pump unit is configured to direct fluid flow from the third syringe cavity into the manifold inlet and the first pump unit is configured to receive fluid flow from the first syringe cavity and the manifold outlet.

3. The syringe control assembly of claim 2 , wherein the fluid manifold is disposed between the syringe mounting rack and the pump assembly.

4. The syringe control assembly of claim 1 , further comprising:
a fourth syringe releasably coupled to the syringe mounting rack, the fourth syringe comprising a fourth syringe body defining a fourth syringe cavity and a fourth syringe port, wherein the fourth syringe port is in fluid communication with the fourth syringe cavity,
wherein the pump assembly further comprises:
a fourth pump unit in fluid communication with the fourth syringe port via a fourth pump tubing, wherein the fourth pump unit is configured to draw fluid flow from the fourth syringe cavity.

5. The syringe control assembly of claim 4 , wherein in a simultaneous delivery configuration the fourth pump unit is configured to draw fluid flow from the fourth syringe cavity while the first pump unit is configured to draw fluid flow from the first syringe cavity.

6. The syringe control assembly of claim 4 , wherein in a sequential delivery configuration the fourth pump unit is configured to draw fluid flow from the fourth syringe cavity after the first pump unit is configured to draw fluid flow from the first syringe cavity.

7. The syringe control assembly of claim 1 , wherein first syringe comprises a first check valve in fluid communication with the first syringe port, wherein the first check valve prevents backflow into the first syringe cavity.

8. The syringe control assembly of claim 1 , wherein second syringe comprises a second check valve in fluid communication with the second syringe port, wherein the second check valve prevents flow out of the second syringe cavity.

9. The syringe control assembly of claim 1 , wherein the valve is configured to provide fluid communication between the first syringe cavity and the second syringe cavity in the priming configuration.

10. The syringe control assembly of claim 1 , wherein the valve is configured to prevent fluid flow from the first syringe cavity via a delivery flow path from entering the catheter in the priming configuration.

11. The syringe control assembly of claim 10 , wherein the valve is configured to direct fluid flow from the first syringe cavity toward the second syringe cavity via a return flow path in the priming configuration.

12. A method to deliver medication, the method comprising:
pumping medication from a first medication syringe into a delivery flow path of a tubing and toward a catheter via a rotary pump in fluid communication with the first medication syringe;
pumping medical fluid from the first medication syringe via a return flow path of the tubing toward a return syringe in fluid communication with the first medication syringe in a priming configuration;
preventing medical fluid from the delivery flow path from entering the catheter via a valve, wherein a first portion of the valve is directly coupled to a terminal end of the delivery flow path and a terminal end of the return flow path, and a second portion of the valve is directly coupled to a terminal end of the catheter; and
directing medical fluid from the delivery flow path to the return flow path through the valve.

13. The method of claim 12 , further comprising:
pumping medical fluid and pumping medication from the first medication syringe simultaneously.

14. The method of claim 12 , further comprising:
pumping saline from a saline syringe into the delivery flow path of the tubing after pumping medication from the first medication syringe.

15. The method of claim 12 , further comprising:
pumping medication from a second medication syringe into the delivery flow path of the tubing.

16. The method of claim 15 , further comprising:
pumping medication from the first medication syringe and the second medication syringe simultaneously.

17. The method of claim 15 , further comprising:
pumping medication from the first medication syringe and the second medication syringe sequentially.

18. A medication delivery system, comprising:
a syringe control assembly, comprising:
an assembly body comprising a syringe mounting rack;
a first syringe releasably coupled to the syringe mounting rack, the first syringe comprising a first syringe body defining a first syringe cavity and a first syringe port, wherein the first syringe port is in fluid communication with the first syringe cavity;
a second syringe releasably coupled to the syringe mounting rack, the second syringe comprising a second syringe body defining a second syringe cavity and a second syringe port
