Abstract

A compact lancing includes a housing, a moveable lancet holder disposed within the housing and configured to hold a lancet, a launching mechanism disposed within the housing, and arming and trigger mechanisms disposed at least partially within the housing. In addition, the launching mechanism includes a launch spring and a retraction spring. The lancet holder, launching mechanism, arming mechanism and trigger mechanism are operatively connected to lance a target site with a lancet held by the moveable lancet holder. In addition, the retraction spring is configured in an essentially concentric arrangement with the launch spring, thereby providing for compactness in design.

Claims

1. A compact lancing device comprising:

a housing;

a moveable lancet holder disposed within the housing and configured to hold a lancet;

a launching mechanism disposed within the housing, the launching mechanism including;

a launch spring; and

a retraction spring

an arming mechanism disposed partially within the housing; and

a trigger mechanism disposed partially within the housing,

wherein the lancet holder, launching mechanism, arming mechanism and trigger mechanism are operatively connected to lance a target site with a lancet held by the moveable lancet holder, and

wherein the retraction spring is configured in an essentially concentric arrangement with the launch spring.

2. The compact lancing device of claim 1, wherein the arming mechanism and trigger mechanism are accessible from a single surface of the housing.

3. The compact lancing mechanism of claim 1 further including a guide member with a groove that limits rotational movement of the lancet holder.

4. The compact lancing mechanism of claim 1, wherein the arming mechanism includes an internal groove that limits rotational movement of the lancet holder.

5. The compact lancing device of claim 1, wherein at least one of the lancet holder, launching mechanism, arming mechanism and trigger mechanism are at least partially formed of a lubricating additive.

6. The compact lancing device of claim 1, wherein a length of the compact lancing device is in the range of 50 mm to 70 mm and a width of the compact lancing device is in the range of about 10 mm to about 20 mm.

7. The compact lancing device of claim 1, wherein an interface between the lancet holder and the arming mechanism is formed of a material that dampens at least one of sound and vibration.
