Abstract

A fluid sampling system is disclosed comprising a fluid drawing device and a fluid sampling device. In one embodiment, the fluid drawing device comprises a venous arterial blood management protection apparatus having a housing with a fill chamber in fluid communication with a patient injection site, a piston positionable within the fill chamber to sealingly engage the fill chamber, wherein the piston has a first position and a second position, wherein movement of the piston from the first position to the second position generates a negative pressure in the fill chamber effective to draw fluid from the patient injection site into the fill chamber, biasing means for biasing the piston to the second position relative to the first position, and securing means for selectively securing the piston in the second position. In one embodiment, the fluid sampling device comprises a base portion having a canula, a handle, and a ridge extending around at least a portion of an outer surface; and a top portion having a flange adapted to engage said the ridge to couple the top portion to the base portion.

Claims

1. A fluid sampling device comprising:

a first portion having a blunt canula, a platform in fluid communication with said blunt canula, and a ridge operatively associated with said platform; and

a second portion having a flange adapted to engage said ridge to couple said second portion to said first portion.

2. The medical device of claim 1, wherein said first portion and said second portion are adapted to be coupled together with a test strip therebetween.

3. The medical device of claim 1, wherein said second portion is adapted to couple to said first portion in a first position and in a second position relative to said first portion, said second portion adapted to be biased toward said second position.

4. The medical device of claim 3, wherein said second portion is in said first position when a test strip is placed between said second portion and said first portion.

5. The medical device of claim 4, further comprising a housing that is adapted to protect said first and second portions from damage and prevent contamination of said blunt canula, said housing comprising:

a substrate that lies adjacent said second portion;

a railing extending from said substrate; and

a cover coupled to said railing and which extends around at least of portion of said first portion.

6. The medical device of claim 5, wherein said second portion moves from said first position to said second position when said test strip is removed from between said first portion and said second portion.

7. The medical device of claim 6, wherein said second portion and said first portion are adapted to remove and retain excess fluid from said test strip when said test strip is removed from between said first portion and said second portion.

8. A medical device comprising:

a blunt canula adapted to be inserted into a sample port of an intravenous tube, said blunt canula comprising a lumen;

a base portion in fluid communication with said blunt canula, said base portion having an aperture in fluid communication with said lumen of said blunt canula; and

a top portion adapted to be coupled to said base portion, said top portion having an aperture therein that is in fluid communication with said aperture of said base portion and said lumen of said blunt canula.

9. The medical device of claim 8, wherein said top portion and said base portion are adapted to receive a test strip therebetween.

10. The medical device of claim 9, wherein said aperture of said top portion is adapted to allow a user to see a portion of said test strip through said aperture of said top portion to determine when a predetermined amount of fluid has been absorbed by said test strip.

11. The medical device of claim 10, wherein said top portion has a recess in a bottom surface thereof and a top surface of said base portion has at least one groove therein, said recess in said top portion and said at least one groove in said base portion are adapted to remove and retain excess fluid from said test strip when said test strip is removed from between said top portion and said base portion.

12. The medical device of claim 9, wherein said top portion is adapted to be coupled to said base portion in a first position and a second position relative to said base portion, said top portion adapted to be biased toward said second position.

13. The medical device of claim 9, wherein said base portion has at least one handle portion.

14. The medical device of claim 9, further comprising a housing that is adapted to enclose said top and base portions and prevent premature exposure of said blunt canula, said housing comprising:

a substrate that lies adjacent said top portion; and

a cover linked to said substrate and which extends around at least a portion of said base portion.

15. A medical device comprising:

a fluid sampling device adapted to be in fluid communication with a sample port of an intravenous tube, said fluid sampling device comprising

a base portion having a blunt canula extending therefrom; and

a top portion adapted to be coupled to said base portion; and

a test strip adapted to be movably placed between said base portion and said top portion, wherein said fluid sampling device is adapted to transfer fluid from the intravenous tube to said test strip through said blunt canula.

16. The medical device of claim 15, wherein said top portion has at least one recess in a bottom surface thereof and said base portion has at least one recess in a top surface thereof, said at least one recess of each of said top portion and said base portion cooperate to remove and retain excess fluid from said test strip when said test strip is removed from said fluid sampling device.

17. The medical device of claim 15, wherein said base portion of said fluid sampling device has an aperture therein that is in fluid communication with said blunt canula and said test strip.

18. The medical device of claim 15, wherein said top portion of said fluid sampling device has an aperture therein adapted to allow a user to determine when a predetermined amount of fluid has been collected on said test strip.

19. The medical device of claim 15, wherein said top portion of said fluid sampling device can be connected to said base portion of said fluid sampling device in a first position and a second position, said top portion being biased toward said second position.

20. The medical device of claim 15, further comprising a housing that is adapted to enclose said fluid sampling device and at least a portion of said test strip to prevent premature exposure of said blunt canula, said housing comprising:

a substrate that lies adjacent said top portion;

a railing extending from said substrate; and

a cover coupled to said railing and which extends around at least a portion of said base portion.
