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.
Claims20
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.

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.

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, 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;
- a tubing defining a delivery flow path and a return flow path, wherein in a priming configuration the delivery flow path and the return flow path are in fluid communication, and the delivery flow path is in fluid communication with the first pump unit to pump fluid flow from the first syringe cavity though the delivery flow path toward a catheter and the return flow path is in fluid communication with the second pump unit to pump fluid flow from the first syringe cavity via the deliver flow path toward the return flow path and the second syringe cavity;
- and
- 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, wherein the valve is configured to prevent fluid flow from delivery flow path from entering the catheter and to direct fluid flow from the delivery flow path through the valve and to the return flow path in the priming configuration.
