Lancing device having a releasable connector

摘要

A lancing device (10) has a spring-loaded lancet holder (20) slidably mounted within a housing (16) for carrying a disposable lancet (40) and needle (42). A slider (26) 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 (28) reversibly immobilizes the holder (20) while the lancet is being ejected. The releasable connector permits a shortened ejection stroke, which, in turn, permits a shorter slot in the housing.
