Lancet-release mechanism

摘要

A lancet-release mechanism is adapted to be incorporated into a lancing device. The lancing device is adapted to receive a lancet assembly therein. The lancing device is adapted to move the lancet assembly between a resting position, a cocking position, and a puncture position. The lancet-release mechanism comprises a lancet holder and a cantilever beam. The lancet holder forms a central aperture. The central aperture is adapted to receive the lancet assembly therein. The lancet holder further forms a plurality of protuberances thereon. The cantilever beam has a projection extending therefrom. The projection is adapted to engage the plurality of protuberances located on the lancet holder. The projection is adapted to separate the plurality of protuberances from each other so as to enlarge the central aperture.

1. A lancet-release mechanism configured to be incorporated into a lancing device, the lancing device configured to receive a lancet assembly therein, the lancing device being configured to move the lancet assembly between a resting position, a cocking position, and a puncture position, the lancet-release mechanism comprising:
a lancet holder including a central aperture, the central aperture being configured to receive the lancet assembly therein, the lancet holder having a first end and a second end opposite the first end, the first end of the lancet holder including a first portion and a second portion, the first and second portions being divided by a plurality of gaps, the second end of the lancet holder being formed in the absence of the plurality of gaps; a first beam having a first end and a second opposing end, the first end of the first beam being attached to the first portion of the lancet holder; a first release button extending from the second opposing end of the first beam; a second beam having a third end and a fourth opposing end, the third end of the second beam being attached to the second portion of the lancet holder; and a second release button extending from the fourth opposing end of the second beam, wherein, in response to the first release button being depressed, the first beam is configured to separate the first portion of the lancet holder from the second portion of the lancet holder, thereby enlarging the first end of the lancet holder without enlarging the second end of the lancet holder, wherein, in response to the second release button being depressed, the second beam is configured to separate the second portion of the lancet holder from the first portion of the lancet holder, thereby enlarging the first end of the lancet holder without enlarging the second end of the lancet holder, wherein, in response to the first release button and the second release button being depressed simultaneously, the first portion of the lancet holder and the second portion of the lancet holder separate, thereby enlarging the first end of the central aperture without enlarging the second end of the central aperture.
