Abstract

A cap for a lancing device includes a cap body with a distal end, a proximal end, an opening through the cap body from the distal end to the proximal end of thereof, and an integrated light source. The distal end of the cap has a target site contact surface and the proximal end is configured for attachment to a lancing device. Moreover, the light source, in combination with the cap body, produces an intense beam of light for illumination and a diffuse light that provides a user with spatial awareness.

Claims

1. A cap for a lancing device comprising:

a cap body with

a distal end with a target site contact surface;

a proximal end for attachment to a lancing device;

an opening through the cap body from the distal end to the proximal end of thereof; and

an integrated light source,

wherein the light source, in combination with the cap body, produces an intense beam of light for illumination and a diffuse light that provides a user with spatial awareness.

2. The cap of claim 1 wherein the cap body is formed at least partially of transparent material.

3. The cap of claim 1 wherein the light source includes a light emitting diode coupled to a light guide.

4. The cap of claim 1 wherein the surface of the cap body is configured to channel light from the integrated light source to produce the intense beam of light.

5. The cap of claim 1 wherein the surface of cap body is configured to convert light from the integrated light source into the diffuse light dependent on light angle of incidence.

6. The cap of claim 1 wherein the light source includes a dedicated battery.

7. The cap of claim 1 wherein the light source includes a timer.

8. The cap of claim 1 wherein the light source includes a light emitting diode that emits green light.

9. The cap of claim 1 wherein the light source includes a light emitting diode that emits yellow light.

10. The cap of claim 1 wherein the light source emits light pulsed at a frequency of at least 50 Hz.

11. The cap of claim 1 wherein the cap body is configured for removable attachment to a lancing device.
