Abstract
Abstract A lancing device has a spring-loaded lancet holder slidably mounted within a housing for carrying a disposable lancet and needle. A slider mounted in a slot in the housing is moved back for cocking the device and, after the lancet is fired, is moved forward to eject the used lancet. A releasable connector reversibly immobilizes the holder while the lancet is being ejected. The releasable connector permits a shortened ejection stroke, which, in turn, permits a shorter slot in the housing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
219 words
A lancing device for withdrawing a blood sample, comprising a generally elongate housing having a cap with a through hole at a forward end and a closure at a back end, opposite the forward end, and containing (a) a lancet holder, slidably mounted within the housing, (b) a first spring for urging the lancet holder forward, having a first end that bears on the housing and a second end that bears on the lancet holder, (c) a slider, slidably mounted in a wall of the housing, comprising (i) a projection outside the wall and (ii) a pushing means, reversibly engageable with the lancet holder, to push the lancet holder back into a cocked position and to push a lancet forward from the device, (d) a second spring for urging the lancet holder back, having a first end that bears on the lancet holder and a second end that bears on the slider, (e) a button, movable between a first position in which the lancet holder is restrained when the device is cocked and a second position in which the restraint is removed, permitting the first spring to thrust the lancet holder forward, and (f) a releasable connector mounted within the housing for immobilizing the lancet holder when the slider is moved forward to eject the lancet from the device.
