Abstract

There is provided a lancet firing device comprising a projection, configured to project into an interior cavity of a lancet body when a lancet having a lancet body is loaded into the firing device; and means to grip an inner wall of the lancet body, the means being disposed on the projection.

Claims

1. A lancet firing device comprising:

a projection, configured to project into an interior cavity of a lancet body when a lancet having a lancet body is loaded into the firing device; and

means to grip an inner wall of the lancet body, said means disposed on said projection.

2. A lancet firing device as claimed in claim 1 wherein said means to grip an inner wall comprises an o-ring, the o-ring being disposed around the projection.

3. A lancet firing device as claimed in claim 2 further comprising a depression in a surface of the projection, the depression configured to receive the o-ring.

4. A lancet firing device as claimed in claim 1 further comprising a supporting wall configured to contact an outer surface of the lancet body.

5. A lancet firing device as claimed in claim 4 wherein the supporting wall is configured to form a friction fit with the lancet body.
