Abstract

A device for priming and venting a hazardous drug within an intravenous administration set. The device includes various access ports and fluid channels to permit direct injection of a hazardous drug into the fluid reservoir, while eliminating the possibility of undesirable exposure to the hazardous drug. The device further includes priming and flushing ports to enable flushing of a hazardous drug from the system following an infusion procedure.

Claims

1. A closed IV solution delivery system for intravenous delivery of a hazardous solution, the system comprising:

a coupling assembly having an input and an output, the input configured for coupling to a primary fluid reservoir to provide flow of a fluid from the primary fluid reservoir to the output;

a drip chamber having an input and an output, the input of the drip chamber coupled directly to the output of the coupling assembly to receive fluid from the flow of the fluid from the primary fluid reservoir to form a secondary fluid reservoir within the drip chamber, the output of the drip chamber being configured to receive a patient conduit, wherein coupling between the input of the coupling assembly and the primary fluid reservoir prevents venting between the drip chamber and an external environment;

a priming port in direct fluid communication with the drip chamber, the priming port having a self-sealing valve thereby preventing venting between the drip chamber and the external environment; and

a membrane disposed within the drip chamber and interposedly positioned between the secondary fluid reservoir and the output of the drip chamber, wherein once wetted, the membrane prevents passage of air from the drip chamber to the output of the drip chamber, thereby preventing venting between the drip chamber and the external environment.

2. The system of claim 1, wherein the self-sealing valve is a split septum.

3. The system of claim 1, wherein the priming port is in direct fluid communication with the drip chamber.

4. The system of claim 1, wherein the priming port is configured to deliver a priming solution directly to the secondary fluid reservoir.

5. The system of claim 1, wherein the patient conduit comprises:

a first end coupled to the output of the drip chamber; and

a second end supporting a flow control plug configured to control flow of air and fluid through the patient conduit.

6. The system of claim 3, wherein the priming port is configured to selectively receive a syringe, and wherein an interaction between the syringe and the priming port prevents venting between the drip chamber and the external environment.

7. The system of claim 3, wherein the priming port comprises a one-way valve configured to permit flow of the priming solution directly into the drip chamber while preventing venting between the drip chamber and the external environment.

8. A closed IV-solution delivery system for intravenous delivery of a hazardous solution, the system comprising:

a coupling assembly having a first fluid channel and a second fluid channel, the first fluid channel having an input and an output, the input being configured for coupling to a primary fluid reservoir to provide flow of a fluid from the primary fluid reservoir to the output, and the second fluid channel having fluidly interconnected first and second ends, the first end being in fluid communication with the primary fluid reservoir, and a second end being in fluid communication with an access port, the access port having a self-sealing valve thereby preventing venting between the primary fluid reservoir and an external environment;

a drip chamber having an input and an output, the input of the drip chamber being directly coupled to the output of the coupling assembly so as to receive the fluid directly from the primary fluid reservoir and form a secondary fluid reservoir within the drip chamber, the drip chamber further including a priming port positioned adjacent to the secondary fluid reservoir and in direct fluid communication with the primary fluid reservoir, the priming port having a self-sealing valve thereby preventing venting between the drip chamber and the external environment, the output of the drip chamber being configured to receive a patient conduit, wherein coupling between the input of the coupling assembly and the primary fluid reservoir prevents venting between the drip chamber and the external environment; and

a membrane disposed within the drip chamber and interposedly positioned between the secondary fluid reservoir and the output of the drip chamber, wherein once wetted, the membrane prevents passage of air from the drip chamber to the output of the drip chamber thereby preventing venting between the drip chamber and the external environment.

9. The system of claim 8, wherein the self-sealing valve of at least one of the access port and the priming port is a split septum.

10. The system of claim 8, wherein the access port is configured to receive a hazardous solution and deliver the hazardous solution directly to the primary fluid reservoir without venting the hazardous solution to the external environment.

11. The system of claim 8, wherein the priming port is configured to receive a priming solution and deliver the priming solution directly to the secondary fluid reservoir without venting the hazardous solution to the external environment.

12. The system of claim 8, wherein the patient conduit comprises:

a first end coupled directly to the output of the drip chamber; and

a second end supporting a flow control plug configured to control flow of air and fluid through the patient conduit thereby preventing venting between the drip chamber and the external environment.

13. The system of claim 8, wherein the access port is configured to selectively receive a syringe, and wherein an interaction between the syringe and the access port prevents venting between the primary fluid reservoir and the external environment.

14. The system of claim 8, wherein the self-sealing valve of the access port permits flow of the hazardous solution from an injection device directly into the primary fluid reservoir without venting the hazardous solution to the external environment.

15. The system of claim 8, wherein the priming port is configured to selectively receive a syringe, and wherein an interaction between the syringe and the priming port prevents venting between the drip chamber and the external environment.

16. The system of claim 8, wherein the self-sealing valve of the priming port permits flow of the priming solution directly into the drip chamber without venting the hazardous solution to the external environment.
