Abstract

This invention relates to a blood collection device and method of use. The device comprises a resilient cup with a top for receiving the patient'"'"'s skin or finger. The top of cup bunches or pinches the skin to increase its surface tension thereby providing a relativity painless piercing by a lancet within the cup. The lancet is supported by a bushing to provide a true cut into the skin without movement of the lancet. The method comprises a safe, relatively painless procedure for collecting blood and transferring it to a test medium for diagnostic purposes.

Claims

1. Blood sampling device comprising;

A) a base;

B) a lid hingedly attached to the base;

C) a resilient cup having a top, bottom which is flexible and expands outwardly upon compression, and side wall mounted on the base;

D) the top of the resilient cup defining an opening for placing the finger to be lanced

E) a lancet attached to the base pointed the top of the cup; and

F) a bushing surrounding the lancet within the flexible cup providing support for the lancet when the resilient cup is compressed.

2. The device described in claim 1 where the resilient cup has a first position when it is relaxed and a second position when it is compressed so that the lancet may pierce a finger or skin placed in the opening on the top of the cup and compressing the cup.

3. The device described in claim 1 wherein the bottom of the cup is flexible and expands outwardly upon compression.

4. The device described in claim 1 wherein the bushing is attached to the base surrounding the lancet.

5. The device described in claim 1 wherein the resilient cup has a wall inside of the sidewall surrounding the bushing, the inside wall and cup being flexible and capable of upward and downward movement.

6. The device described in claim 5 wherein in the first position the inside wall and bottom of the cup are relaxed and in a second position wherein the cup is compressed by a finger or skin surface moving the cup and inside wall downward and expanding the bottom of the cup outwardly allowing the lancet to remain motionless to pierce the skin.

7. The device described in claim 5 wherein a plurality of cross-members connect the side wall and inside wall of the cup providing support to cup.

8. The device described in claim 5 wherein the resilient cup having cross-members connecting the side wall and inside wall, the inside wall operatively associated with the bushing which vertically supports the sterile lancet providing limited penetration into a finger or skin surface compressing the resilient cup.

9. A blood sampling device comprising:

(a) a base;

(b) a lid hingedly attached to the base;

(c) a resilient cup having a top, a bottom which is flexible and expands outwardly upon compression, and sidewall mounted on the base;

(d) the top of the resilient cup defining an opening for placing a finger or skin to be lanced;

(e) a lancet attached to the base pointed to the top of the cup;

(f) a bushing surrounding the lancet within the flexible cup providing support for the lancet when the resilient cup is compressed, the resilient cup having a first position when is relaxed and a second position when it is compressed so that the lancet may pierce the finger to skin placed in the opening on the top of the cup and compressing the cup.
