Abstract

A blood test strip useful for venting a closed intravenous system and collecting a blood sample is described herein. The blood test strip includes a blood test strip, one or more vents, and a gripping member coupled to the proximal end of the blood test strip. The one or more vents are disposed between the distal and the proximal portions of the blood test strip.

Claims

1. An intravenous catheter system comprising:

an intravenous catheter;

an access port coupled to the intravenous catheter;

a venting device shaped and sized to selectively access the port, a proximal portion of the venting device having a gripping member, a distal portion of the venting device having a blood test member.

2. The intravenous catheter system of claim 1, wherein blood test member is a blood test strip extending distally from the gripping member.

3. The intravenous catheter system of claim 2, wherein the access port includes a septum, and wherein the blood test strip is selectively disposed within a slit of the septum.

4. The intravenous catheter system of claim 3, wherein the septum has a thickness between a proximal side and a distal side of the septum, the one or more vents having a length longer than the septum thickness.

5. The intravenous catheter system of claim 3, wherein the gripping member is a cap that is shaped and sized to cover the septum.

6. The intravenous catheter system of claim 3, wherein the blood test strip includes one or more reservoirs that collectively retain blood therein when drawn through the slit of the septum.

7. The intravenous catheter system of claim 1, wherein the venting device includes one or more vents extending therethrough.

8. The intravenous catheter system of claim 1, wherein the one or more vents includes at least one of a hole having dimensions that permits the passage of gas but not blood, a gas permeable membrane, and a channel formed on an outer surface of the blood test member having dimensions that permits the passage of gas but not blood.

9. The intravenous catheter system of claim 1, wherein the one or more vents extends through at least one of the gripping member, the blood test member, and both the gripping member and the blood test member.

10. The intravenous catheter system of claim 1, wherein the access port includes a luer connector, and wherein the gripping member includes a cap that selectively connects to the luer connector.

11. The intravenous catheter system of claim 1, wherein the blood test strip includes at least one diagnostic reagent thereon.

12. A blood test strip comprising:

a blood test strip;

one or more vents disposed between a distal portion and a proximal portion of the blood test strip;

a gripping member coupled to the proximal end of the blood test strip.

13. The blood test strip of claim 12, wherein the one or more vents are further disposed through the gripping member.

14. The blood test strip of claim 12, wherein the one or more vents include at least one of a hole having dimensions that permits the passage of gas but not blood, a gas permeable membrane, and a channel formed on an outer surface of the blood test member having dimensions that permits the passage of gas but not blood.

15. The blood test strip of claim 12, wherein the gripping member is a cap that is shaped and sized to cover a female luer adapter.

16. The blood test strip of claim 12, wherein the gripping member is gripping tab.

17. The blood test strip of claim 12, wherein the blood test strip includes at least one diagnostic reagent thereon.

18. A method for venting a closed intravenous system and for blood collecting, the method comprising:

providing a venting device having at least one vent disposed therethrough and having a blood test member coupled thereto;

inserting the blood test member of the venting device at least partially into an access port of the closed intravenous catheter system;

venting gas from the closed intravenous catheter system through at least one vent in the venting device; and

withdrawing the blood test member from the access port after the blood test member collects blood from within the closed intravenous catheter system.

19. The method of claim 18, further comprising using the blood test member to test the collected blood.

20. The method of claim 18, wherein the blood test member is a blood test strip wherein venting gas includes venting gas through at least one vent in the blood test stip.
