Lancet release mechanism

摘要

A lancing device comprises a lancet holder and a lancet-release mechanism. The lancet holder forms an aperture. The aperture is adapted to receive a lancet assembly therein. The lancet holder is adapted to move the lancet assembly between a resting position, a cocking position, and a puncture position. The lancet-release mechanism includes a release button located adjacent to and external from the lancing device and a beam attached to the release button. The beam extends into the lancing device and the lancet holder. The beam is adapted to engage the lancet assembly. The release button and attached beam are adapted to eject the lancet assembly from the lancet holder.

1. A lancing device comprising:
a lancet holder having an aperture, the aperture being configured to receive a lancet assembly therein, the lancet holder being configured to move the lancet assembly between a resting position, a cocking position, and a puncture position; and a lancet-release mechanism including
(i) a release button located adjacent to and external from the lancing device,(ii) a beam attached to the release button, the beam extending into the lancing device and the lancet holder, the beam being configured to engage the lancet assembly, and(iii) a spring located adjacent to and engaging the beam, the spring being configured to contract as the lancet assembly is received by the lancet holder, wherein the release button and the attached beam, along with the spring, are positioned to eject the lancet assembly from the lancet holder by biasing the beam against the lancet assembly, the biasing at least partially due to the spring expanding from a compressed state.
