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.

Lancing device having a releasable connector

A lancing device has a spring-loaded lancet holder slidably mounted within a housing for carrying a disposable lancet and needle. A knob on the back of the device has forward-extending fingers that stop the lancet holder at an adjustable predetermined point after the device has been fired. The fingers not only control the penetration depth of the needle, but also absorb vibrations and reduce noise to cause less pain to the user.

Lancing device causing reduced pain

A blood sampling device is provided with a housing, a lancet assembly, a lancet holder disposed in the housing for supporting the lancet assembly, the lancet holder being movable in a lancing direction between a cocked position and a puncture position, a drive spring for forcing the lancet holder from the cocked position to the puncture position, and a mechanism for damping movement of the lancet holder during travel of the lancet holder from the puncture position to an intermediate position between the puncture position and the cocked position. The damping mechanism may be provided in the form of a non-planar surface, such as a corrugated surface, disposed on the lancet holder and a damping member which makes contact with the non-planar surface during movement of the lancet holder.

Blood sampling device with lancet damping system

A blood sampling device is provided with a housing, a lancet assembly, a lancet holder which is movable in a lancing direction between a cocked position and a puncture position, and an actuator mechanism disposed in the housing for causing the lancet holder to move from the cocked position to the puncture position. The lancet assembly has a lancet with a sharp tip, a lancet body having at least two angularly spaced ribs which extend outwardly from a central portion of the lancet body, and a protective cap covering the sharp tip of the lancet, the protective cap being attached to the lancet body so that the protective cap is twistably removable from the lancet body. The lancet holder has an aperture formed therein, the aperture having a cylindrical shape and being substantially unobstructed so that the lancet body may be inserted into the aperture in any angular orientation relative to the lancet holder, and the blood sampling device includes a mechanism for preventing significant rotational movement of the lancet body relative to the lancet holder when the lancet body is disposed in the aperture formed in the lancet holder and when the protective cap is subject to an angular force sufficient to twist the protective cap off of the lancet body.
