Abstract

A-type blood transfusion set having a blood limb, a saline limp and common limb and a one-way saline valve provided in the saline limb which only allows fluid within the saline limb to flow toward the Y connector. The blood limb and saline limb are color coded or marked with some type of identification so that, prior to coupling the blood limb to a source of blood or the saline limb to a source of saline, visual identification of the saline limb, having the one-way saline valve therein, can be readily achieved.

Claims

1. In a y-type blood transfusion set having a blood limb, saline limp and common limb which are coupled together at a Y connector, the improvement comprising a one-way saline valve provided in the saline limb which only allows fluid within the saline limb to flow toward the Y connector.

2. A y-type blood transfusion set according to claim 1, further comprising at least one of a distinguishing color or indicia associated with at least one of the blood limb or saline limb which provides for visually differentiating the blood limb from the saline limb.

3. A y-type blood transfusion set according to claim 2, wherein at least one of the blood limb and the saline limb are at least partially color coded with a distinguishing color.

4. A y-type blood transfusion set according to claim 3, wherein each of the blood limb and the saline limb are at least partially color coded with a different color.

5. A y-type blood transfusion set according to claim 2, wherein at least one of the blood limb and the saline limb are provided with differentiating indicia.

6. A y-type blood transfusion set according to claim 5, wherein the differentiating indicia comprises at least one of symbols, text and numbers.

7. A y-type blood transfusion set according to claim 2, wherein each of the blood limb and saline limb includes a spike for fluidly coupling respective limb to a bag or bottle of fluid and the spike or at least one of the blood limb or saline limb is provided with the distinguishing color or indicia.

8. A y-type blood transfusion set which comprises:

a blood limb that includes;

a length of tubing having first and second ends,

a spike coupled to the first end of the tubing, and

an external flow regulator provided on the tubing;

a saline limb that includes;

a length of tubing having first and second ends,

a spike coupled to the first end of the tubing,

an external flow regulator provided on the tubing, and

a one-way saline valve provided between the first end of the tubing and the external flow regulator;

a common limb having a first and second ends; and

a Y-connector coupled to the second ends of each of the lengths of tubing of the blood limb and the saline limb and the first end of the common limb.

9. A y-type blood transfusion set according to claim 8, further comprising at least one of a distinguishing color or indicia associated with at least one of the blood limb or saline limb which provides for visually differentiating the blood limb from the saline limb.

10. A y-type blood transfusion set according to claim 9, wherein at least one of the blood limb and the saline limb are at least partially color coded with a distinguishing color.

11. A y-type blood transfusion set according to claim 10, wherein each of the blood limb and the saline limb are at least partially color coded with a different color.

12. A y-type blood transfusion set according to claim 8, wherein at least one of the blood limb and the saline limb are provided with differentiating indicia.

13. A y-type blood transfusion set according to claim 12, wherein the differentiating indicia comprises at least one of symbols, text and numbers.

14. A y-type blood transfusion set according to claim 8, wherein each of the blood limb and saline limb includes a spike for fluidly coupling respective limb to a bag or bottle of fluid and the spike or at least one of the blood limb or saline limb is provided with the distinguishing color or indicia.

15. A y-type blood transfusion set according to claim 8, wherein the common limb further comprises an external flow regulator on the length of tubing of the common limb.

16. A y-type blood transfusion set according to claim 15, wherein the common limb further comprises at least one injection portal in fluid communication to the length of tubing of the common limb.

17. A y-type blood transfusion set according to claim 15, wherein the common limb further comprises a blood filter.

18. A method of transfusing blood into a patient using a y-type blood transfusion set having a blood limb, saline limp and common limb which are coupled together at a Y connector, the method comprising the steps of:

providing a one-way saline valve provided in the saline limb which only allows fluid within the saline limb to flow toward the Y connector;

coupling the blood limb to source of a blood product;

coupling the saline limb to a source of saline;

coupling the common limb to a patient; and

allowing the one-way saline valve to prevent fluid flow towards the source of saline while transfusing blood into the patient.

19. A method of transfusing blood into a patient according to claim 18, further comprising warming the blood before the blood is transfused into the patient.

20. A method of transfusing blood into a patient, further comprising filtering the blood as it flows through the common limb.
