Abstract

A method for lancing a target site in low ambient light conditions includes employing diffuse light produced by an integrated light source of a lancing device to achieve user spatial awareness in a low ambient light condition. The method further includes illuminating a target site, also in the low ambient light condition, with an intense beam of light from the integrated light source and urging the lancing device against the target site. Subsequently, the target site is lanced with a lancet held by the lancing device.

Claims

1. A method for lancing a target site in low ambient light conditions, the method comprising:

employing diffuse light produced by an integrated light source of a lancing device to achieve user spatial awareness in a low ambient light condition;

illuminating a target site, in the low ambient light condition, with an intense beam of light from the integrated light source;

urging the lancing device against the target site; and

lancing the target site with a lancet held by the lancing device.

2. The method of claim 1 further including the step of locating blood glucose kit ancillary items with the aid of at least one of the intense beam of light and the diffuse light.

3. The method of claim 2 wherein the locating step occurs while the lancing device is positioned on a lancing device stand.

4. The method of claim 1 wherein further including, prior to the lancing step, a step of verifying a lancing device depth gauge setting that has been illuminated by the integrated light source.

5. The method of claim 1 further including, after the lancing step, the step of deactivating the light source via automatic operation of an integrated light source timer.

6. The method of claim 1 further including the step of using at least one the diffuse light and the intense beam of light to aid in the manipulation of at least one blood glucose kit ancillary item.

7. The method of claim 6 wherein the using step occurs while the lancing device is positioned on a lancing device stand.

8. The method of claim 1 further including the step of using at least one the diffuse light and the intense beam of light to aid in the employment of at least one blood glucose kit ancillary item.

9. The method of claim 8 wherein the using step occurs while the lancing device is positioned on a lancing device stand.

10. The method of claim 1 wherein the lancing step includes lancing a dermal tissue target site for the expression of a whole blood sample.
