Abstract

A finger guide for testing blood glucose and associated methods are disclosed. More particularly, a blood glucose testing system is provided that includes a finger guide that is wearable by the subject of the blood glucose test and a glucose meter that is retrofitted with a glucose meter coupler. A method of operating the blood glucose testing system includes the steps of guiding a lancing device to a spot on the subject'"'"'s finger for producing a blood droplet and guiding a test strip in the glucose meter to the same spot on the subject'"'"'s finger for testing the blood sample.

Claims

1. A blood glucose testing system, comprising:

a finger guide, wherein the finger guide comprises;

a finger guide body;

a finger guide sleeve; and

a finger guide opening disposed within the finger guide sleeve; and

a glucose meter coupler, wherein the glucose meter coupler comprises;

a locking mechanism configured to attach the glucose meter coupler to a glucose meter, and

a coupling feature configured to couple a glucose meter and the glucose meter coupler installed thereon to the finger guide via the finger guide opening, wherein the coupling feature further comprises a test strip opening configured to allow a test strip to pass from the glucose meter to a finger positioned within the finger guide.

2. The blood glucose testing system of claim 1, wherein the finger guide is secured to the finger in a splint-like manner.

3. The blood glucose testing system of claim 1, wherein the finger guide further comprises a finger guide strap.

4. The blood glucose testing system of claim 3, wherein the finger guide strap further comprises a securing mechanism.

5. The blood glucose testing system of claim 4, wherein the securing mechanism is Velcro®

.

6. The blood glucose testing system of claim 1, wherein the finger guide further comprises finger guide padding.

7. The blood glucose testing system of claim 6, wherein the finger guide padding further comprises a finger guide padding opening having dimensions substantially similar to the finger guide opening.

8. The blood glucose testing system of claim 6, wherein the finger guide padding is comprised of foam.

9. The blood glucose testing system of claim 6, wherein the finger guide padding is comprised of rubber.

10. The blood glucose testing system of claim 1, wherein the finger guide opening is further configured to receive a lancing device.

11. The blood glucose testing system of claim 1, wherein the finger guide body is comprised of plastic.

12. The blood glucose testing system of claim 1, wherein the glucose meter coupler comprises a battery cover portion configured to replace a battery cover of the glucose meter.

13. The blood glucose testing system of claim 12, wherein the locking mechanism comprises a locking tab configured to operatively clip into corresponding features in a battery compartment of the glucose meter.

14. The blood glucose testing system of claim 13, wherein the locking tab is configured to be unclipped from the corresponding features of the battery compartment to facilitate removal of the glucose meter coupler from the glucose meter.

15. The blood glucose testing system of claim 12, wherein the glucose meter coupler further comprises an arm connecting the battery cover portion to the coupling feature.

16. The blood glucose testing system of claim 1, wherein the system further comprises alignment features disposed on the finger guide sleeve and the coupling feature, wherein the alignment features of the finger guide sleeve are configured to substantially align with the alignment features of the coupling feature, thereby enabling consistent orientation of the finger guide relative to the glucose meter coupler when coupled together.

17. The blood glucose testing system of claim 16, wherein the alignment features of the finger guide sleeve comprise alignment slots configured to receive corresponding raised alignment features disposed on an outer perimeter of the coupling feature.

18. The blood glucose testing system of claim 17, wherein the finger guide sleeve comprises two alignment slots and the outer perimeter of the coupling feature comprises two corresponding raised features.

19. A method of using a blood glucose testing system comprising the steps of:

a) providing a standard glucose meter, wherein the glucose meter comprises a battery compartment, a battery cover, and a test strip receptacle;

b) removing the battery cover;

c) providing a glucose meter coupler and installing the glucose meter coupler on the glucose meter in place of the battery cover, wherein the glucose meter coupler comprises a coupling feature;

d) inserting a test strip through a test strip opening of the coupling feature and into the test strip receptacle;

e) providing a finger guide, wherein the finger guide comprises a finger guide body, a finger guide sleeve, and a finger guide opening disposed within the finger guide sleeve;

f) securing the finger guide to a subject'"'"'s finger;

g) inserting a lancing device into the finger guide opening and pricking the subject'"'"'s finger;

h) removing the lancing device from the finger guide, leaving a blood droplet behind in a desired location relative to the finger guide;

i) pressing the coupling feature of the glucose meter coupler into the finger guide opening such that the test strip contacts the blood droplet on the subject'"'"'s finger, thereby enabling the glucose meter to compute a blood glucose level;

j) removing the glucose meter coupler and attached glucose meter from the finger guide;

k) removing the finger guide from the subject'"'"'s finger; and

l) reading the blood glucose level from a display on the glucose meter.

20. The method of claim 19, wherein the finger guide sleeve and the coupling feature of the glucose meter coupler further comprise alignment features that ensure the finger guide is desirably aligned relative to the glucose meter coupler when coupled together.
