Abstract

The present invention provides a method for safely infusing a toxic fluid into a patient using an extension set, a connect set and a cyto admin set, the extension set comprising an extension set line, and first and second syringes, wherein the extension set line provides fluid communication between a toxic fluid container and the syringes such that toxic fluid may be moved from within the toxic fluid container into one of the syringes, the connect set comprising a connect set line in fluid communication with an infusion bag, wherein the connect set includes a port for connection with the extension set such that the syringes are in fluid communication with the infusion bag, the cyto admin set comprising one or more check valves for connection with the connect set such that the infusion bag is in fluid communication with the cyto admin set, the method comprising drawing the toxic fluid from the toxic fluid container through the extension set line into the first syringe, flushing the extension set line using fluid from the second syringe, disconnecting the extension set from the toxic fluid container, attaching the extension set to the connect set such that fluid communication is established therebetween, injecting the toxic fluid from the first syringe into the infusion bag, flushing the extension set line using fluid from the second syringe, attaching the connect set to the cyto admin set and infusing the toxic fluid from the infusion bag into the patient.

Claims

1. A method for safely infusing a toxic fluid into a patient using an extension set, a connect set and a cyto admin set, the extension set comprising an extension set line, and first and second syringes, wherein the extension set line provides fluid communication between a toxic fluid container and the syringes such that toxic fluid may be moved from within the toxic fluid container into one of the syringes, the connect set comprising a connect set line in fluid communication with an infusion bag, wherein the connect set includes a port for connection with the extension set such that the syringes are in fluid communication with the infusion bag, the cyto admin set comprising one or more check valves for connection with the connect set such that the infusion bag is in fluid communication with the cyto admin set, the method comprising the steps of:

drawing the toxic fluid from the toxic fluid container through the extension set line into the first syringe;

flushing the extension set line using fluid from the second syringe;

disconnecting the extension set from the toxic fluid container;

attaching the extension set to the connect set such that fluid communication is established therebetween;

injecting the toxic fluid from the first syringe into the infusion bag;

flushing the extension set line using fluid from the second syringe;

attaching the connect set to the cyto admin set; and

infusing the toxic fluid from the infusion bag into the patient.

2. The method of claim 1, further comprising the step of puncturing the toxic fluid container using a vial spike of the extension set to allow fluid flow of the toxic drug from the toxic fluid container into the first syringe.

3. The method of claim 2, wherein the vial spike includes an inline filtration membrane that allows the drug to be filtered as it is withdrawn from drug container.

4. The method of claim 1, further comprising the step of clamping off a primary line of the cyto admin set for the passage of saline or neutral fluids into the patient while the toxic fluid is being infused into the patient.

5. The method of claim 1, further comprising the step of manually kneading the infusion bag to mix the fluid contained therein before infusing the fluid into the patient.

6. The method of claim 1, wherein the step of drawing the toxic fluid into a first syringe comprises turning an extension set stopcock to a first position to allow fluid flow of the toxic fluid from the toxic fluid container, through an extension set line, and into the first extension set syringe.

7. The method of claim 6, wherein the step of flushing the extension set line using a second syringe includes the step of turning the stopcock to a second position to allow fluid flow between the second syringe and the toxic fluid container such that the second syringe empties approximately one half of a flush solution through the extension set line and into the toxic fluid container.

8. The method of claim 7, further comprising the step of turning the stopcock to third, closed position prior to disconnecting the extension set.

9. The method of claim 1, wherein the cyto admin set further comprises a dedicated universal spike adapter for connection with any spike on any conventional pump set.

10. The method of claim 1, wherein the stopcock includes a stop post that prevents the first and second syringes from being opened at the same time.

14. The system of claim 11, wherein a primary line of the cyto admin set for the passage of saline or neutral fluids into the patient is clamped off while the toxic fluid is being infused into the patient.

16. The system of claim 11, wherein the toxic fluid is drawn into the first syringe by turning a stopcock to a first position to allow fluid flow of the toxic fluid from the toxic fluid container, through an extension set line, and into the first extension set syringe.

17. The system of claim 16, the extension set line is flushed by turning the stopcock to a second position to allow fluid flow between the second syringe and the toxic fluid container such that the second syringe empties a flush solution through the extension set line and into the toxic fluid container.

18. The system of claim 17, wherein the stopcock is turned to a third, closed position prior to disconnecting the extension set.

19. The system of claim 11, wherein the cyto admin set further comprises a dedicated universal spike adapter for connection with any spike on any conventional pump set.

11. A system for safely infusing a toxic fluid into a patient, the system comprising:

an extension set comprising an extension set line, and first and second syringes, the extension set line providing fluid communication between a toxic fluid container and the syringes such that toxic fluid may be moved from within the toxic fluid container into one of the syringes;

a connect set comprising a connect set line in fluid communication with an infusion bag, the connect set including a port for connection with the extension set such that the syringes are in fluid communication with the infusion bag; and

a cyto admin set comprising one or more check valves for connection with the connect set such that the infusion bag is in fluid communication with the cyto admin set;

wherein toxic fluid is drawn from the toxic fluid container through the extension set line into the first syringe;

wherein the extension set line is flushed using fluid from the second syringe;

wherein the extension set is disconnected from the toxic fluid container and attached to the connect set such that fluid communication is established therebetween;

wherein the toxic fluid from the first syringe is injected into the infusion bag;

wherein the extension set line is flushed using fluid from the second syringe;

wherein the connect set is connected to the cyto admin set;

wherein the toxic fluid in the infusion bag is infused into the patient.

12. The system of claim 11, wherein the extension set further comprises a vial spike for puncturing the toxic fluid container to allow fluid flow of the toxic drug from the toxic fluid container into the first syringe.

13. The system of claim 12, wherein the vial spike includes an inline filtration membrane that allows the drug to be filtered as it is withdrawn from drug container.

15. The system of claim 11, wherein the infusion bag is manually kneaded to mix the fluid contained therein before infusing the fluid into the patient.

20. The system of claim 11, wherein the stopcock includes a stop post that prevents the first and second syringes from being opened at the same time.
