Abstract

The present invention recognizes that there is a need for a single-step, pain-free or substantially pain-free device to test the levels of an analyte in one'"'"'s blood such as glucose. The invention incorporates a lancet and a glucose test strip into a disposable cartridge. The user inserts the cartridge into the port of the device to turn it on. The base vibrates to quench or reduce pain from a lancet puncture. The test strip is exposed to the blood sample at the site of the lancet puncture which is analyzed by the device.

Claims

1. A blood diagnostic device which produces a pain-less or near pain-less lancet puncture composed of:

a) a port for a lancet cartridge,

b) a lancet cartridge with an internal lancet and internal test strip,

c) a motor to cause physical vibration at or near the at least one open end or port and

d) a means of ejecting said internal lancet from said lancet cartridge to cause a puncture in the skin and produce a blood sample for analysis.

2. The blood diagnostic device of claim 1 wherein said internal test strip measures an analyte such as glucose in the blood.

3. The blood diagnostic device of claim 1 which includes a digital monitor to display the measured value of an analyte such as glucose to the user.

4. The blood diagnostic device of claim 1 wherein said lancet cartridge is disposable or single use.

5. The blood diagnostic device of claim 1 wherein the user activates said physical vibration by pressure against the base of the device against a patient'"'"'s or subjects skin or tissue.

6. The blood diagnostic device of claim 1 wherein the user activates said lancet cartridge by pressure against the base of the device against a patient'"'"'s or subjects skin or tissue.

7. The blood diagnostic device of claim 1 wherein the tip of said internal lancet retracts after ejecting.

8. The blood diagnostic device of claim 1 wherein said internal test strip uses capillary action to contact a blood sample.

9. The blood diagnostic device of claim 1 wherein the user can adjust the distance that said internal lancet is ejected from said lancet cartridge.

10. The blood diagnostic device of claim 1 wherein said measured value is recorded digitally or relayed to a computer or other electronic device.

11. The blood diagnostic device of claim 1 wherein a said lancet cartridge includes a syringe.

12. The blood diagnostic device of claim 1 which includes a syringe for withdrawing blood from a human or animal for diagnostic purposes.

13. The blood diagnostic device of claim 1 which includes a syringe for injecting a drug, steroid, insulin or immunization solution into a human or animal.

14. A method of measuring blood glucose levels in a human or mammal by inflicting little or no pain using the blood glucose meter device of claim 1, comprising the steps of:

a) activating the device to vibrate against the skin of a subject or patient,

b) triggering said lancet eject to puncture the skin and produce a blood sample,

c) allowing said test strip to contact said sample of blood,

d) displaying the concentration of an analyte value such as glucose to the user on a screen or audibly with a speaker.

15. The method of claim 14 wherein said blood glucose meter device is turned on by inserting a lancet cartridge into the base or port.

16. The method of claim 14 wherein said lancet assembly is intended for single use or disposable.

17. The method of claim 14 wherein said test strip is positioned less than five millimeter asay from the tip of said lancet.

18. The method of claim 14 wherein said test strip is ejected with or after said lancet tip is expelled out of the open end.

19. The method of claim 14 wherein said test strip uses capillary action to contact a blood sample.

20. The method of claim 14 wherein the user may adjust the distance that said internal lancet is ejected from said lancet cartridge.

21. The method of claim 14 wherein said lancet device is used for withdrawing blood from a human or animal for diagnostic purposes.

22. The method of claim 14 wherein said lancet cartridge contains a syringe for withdrawing blood.

23. The method of claim 14 wherein said lancet cartridge contains a syringe for injecting a substance such as an analyte, drug, steroid, insulin or immunization into a subject.

24. A lancet assembly for making a skin puncture and a resulting blood sample comprising:

a) a housing with a spring or pressure loaded lancet,

b) said housing having at least one open end,

c) a triggering device for ejecting said lancet from said at least one open end and

d) a test strip for analyzing an analyte such as glucose.

25. The lancet device of claim 24 wherein said lancet device is sterile and intended for single use or disposable.

26. The assembly of claim 24 wherein said lancet assembly comprises nonconductive material.

27. The assembly of claim 24 wherein said test strip is ejected with or after said lancet tip is expelled out of the open end.

28. The assembly of claim 24 wherein said test strip uses capillary action to contact a blood sample.

29. The assembly of claim 24 wherein said triggering device may be adjusted to increase or decrease the distance that it is ejected from said housing.
