Abstract

A lancet device used for drawing a blood sample for testing has a lancet, a lancet holding mechanism, a lancet activation plunger, and a removable lancet cap with an opening for touching against the human body. The lancet has a needle, where the needle is movable inside the cap with the lancet activation plunger. The lancet device has positioned inside the device, a disinfectant material, disinfecting the lancet needle for each use. The disinfectant material lets the needle move or rest inside the disinfectant material disinfecting the needle between each use. The lancet needle moves through the disinfectant material when used, disinfecting the needle for each use.

Claims

1. A lancet device used for drawing blood sample for testing comprising:

a. the lancet device has a lancet, a lancet holding mechanism, a lancet activation plunger, and a lancet cap with an opening for touching against the human body, the lancet has a needle, where the needle is movable inside the cap with the lancet activation plunger;

b. a disinfectant material is positioned inside the lancet device or as part of the lancet device that disinfects the needle for each use of the lancet.

2. The device as in claim 1, comprising:

the disinfectant material is made of sponge like material that holds a disinfectant and lets the needle move or rest inside the disinfectant material.

3. The device as in claim 1, comprising:

the lancet needle rests inside the disinfectant material, when not plunged, disinfecting the needle between each use.

4. The device as in claim 1, comprising:

the lancet needle moves through the disinfectant material when used, disinfecting the needle for each use.

5. The device as in claim 1, comprising:

the disinfectant material is positioned inside the cap, disinfecting the lancet needle for each use.

6. The device as in claim 5, comprising:

the disinfectant material is in the shape of a disc that is positioned inside the cap.

7. The device as in claim 6, comprising:

the disinfectant material is in the shape of a disc that is positioned inside the cap, the thickness of the disc is at least a 1 mm to 3 mm thick and positions the needle inside the disc.

8. A method for a lancet device used for drawing blood sample for testing comprising the steps of:

a. having the lancet device with a lancet, a lancet holding mechanism, a lancet activation plunger, and a removable lancet cap with an opening for touching against the human body, having the lancet with a needle, where the needle is movable inside the cap with the lancet activation plunger;

b. positioning a disinfectant material inside the lancet device, disinfecting the lancet needle for each use.

9. The method for device as in claim 8, comprising the steps of:

making the disinfectant material of sponge like material for holding a disinfectant and for moving or resting the needle inside the disinfectant material.

10. The method for device as in claim 8, comprising the steps of:

resting the lancet needle inside the disinfectant material, when not plunged, disinfecting the needle between each use.

11. The method for device as in claim 8, comprising the steps of:

moving the lancet needle through the disinfectant material when used, disinfecting the needle for each use.

12. The method for device as in claim 8, comprising the steps of:

shaping the disinfectant material in the form of a disc, for positioning inside the lancet cap, as a disinfectant material that is used for disinfecting the lancet needle for each use.

13. The method for device as in claim 8, comprising the steps of:

shaping the disinfectant material as a disc for positioning inside the cap, where the thickness of the disc is at least a 1 mm to 3 mm thick for positioning and moving the needle inside the disc.

14. The method for device as in claim 8, comprising the steps of:

shaping the disinfectant material as a disc and positioning the disc inside the cap at the bottom of the cap.

15. A lancet device used for drawing blood sample for testing, has a lancet, a lancet holding mechanism, a lancet activation plunger, and a removable lancet cap with an opening for touching against the human body, the lancet has a needle, where the needle is movable inside the cap with the lancet activation plunger, comprising:

the lancet cap has positioned inside the cap a disinfectant material, disinfecting the lancet needle for each use.

16. The device as in claim 15, comprising:

the disinfectant material is made of sponge like material that holds a disinfectant and lets the needle move or rest inside the disinfectant material.

17. The device as in claim 15, comprising:

the lancet needle rests inside the disinfectant material, when not plunged, disinfecting the needle between each use, alternatively the lancet needle moves through the disinfectant material when used, disinfecting the needle for each use.

18. A method for a lancet device used for drawing blood sample for testing having the lancet device with a lancet, a lancet holding mechanism, a lancet activation plunger, and a removable lancet cap with an opening for touching against the human body, having the lancet with a needle, where the needle is movable inside the cap with the lancet activation plunger comprising the steps of:

positioning inside the lancet cap a disinfectant material, disinfecting the lancet needle for each use.

19. The method for device as in claim 18, comprising the steps of:

making the disinfectant material of sponge like material for holding a disinfectant and for moving or resting the needle inside the disinfectant material.

20. The method for device as in claim 18, comprising the steps of:

a. resting the lancet needle inside the disinfectant material, when not plunged, disinfecting the needle between each use, alternatively;

b. moving the lancet needle through the disinfectant material when used, disinfecting the needle for each use.
