Abstract

A blood collector comprises a thin flexible tube, which adheres to a person'"'"'s finger, and the finger is punctured through the tube. The outside surface of the tube is sealed after the puncture, and a quantity of blood from the finger is collected in the tube.

Claims

1. A disposable, nonreusable plastic blood collector for collecting a small sample of blood, comprising:

a means to attach a tube to a person'"'"'s finger with adhesive and

means to seal an outside surface of the tube after a lanced puncture is made through said tube.

2. The blood collector according to claim 1, wherein said tube is constructed of thin flexible plastic sheet material.

3. The blood collector according to claim 2, wherein said tube consists of a plurality of narrow passageways and chambers, one of said chambers adapted to store reagents.

4. The blood collector according to claim 2, wherein said tube is attached to a pull tab which axially overlies the tube.

5. The blood collector according to claim 4 wherein said pull tab contains a hole which is positioned over the location of said lanced puncture.

6. The blood collector according to claim 2, wherein said tube includes a fitting at one end thereof, whereby an accessory may be attached to said tube.

7. The blood collector according to claim 1, wherein said adhesive is a thin flexible adhesive sheet with the tube firmly attached only in a small area in the middle of the said adhesive sheet.

8. The blood collector according to claim 7, wherein said tube is constructed of thin flexible plastic sheet material.

9. The blood collector according to claim 8, wherein said tube is attached to a pull tab that axially overlies the tube, and said pull tab is contained within a plastic sleeve with said adhesive sheet positioned external to the sleeve.

10. The blood collector according to claim 9 wherein said sleeve includes a strip of plastic positioned perpendicular to the axis of the sleeve for the purpose of acting as a stop and sealer of the tube when the pull tab is pulled out.

11. The blood collector according to claim 10 wherein said sleeve contains a cross slit for the purpose of breaking the sleeve off at said cross-section.

12. The blood collector according to claim 10 wherein said sleeve and tube comprises of means to maintain a sealed condition of the tube within the sleeve after the tab is pulled out.

13. The blood collector according to claim 1, wherein said means to seal the outside surface of the tube after a lanced puncture is done consists of a thin sheet of pliable sealing material which is radially precompressed when bonded to the tube.

14. A method of collecting blood from a person'"'"'s finger comprising the steps of applying a flexible tube to a finger, puncturing the finger through said tube, and sealing the outside surface of said tube after said puncturing.

15. The method according to claim 14, including the step of cleaning said finger with a diluted adhesive compound.

16. The method according to claim 14, including the step of winding a string about each finger for the purpose of extruding the desired amount of blood.
