Lancing Device for One Skin Puncture
First Claim
1. A lancing device comprising:
- a main housing forming an inner aperture enclosing a portion of a lancet assembly, the lancet assembly having a lancet body, a lancet-plunger housing, and a lance, the lancet assembly being adapted to move between a resting position, a cocking position, and a puncture position;
a movable housing adjacent the main housing, being adapted to move from a resting position to a cocking position, and being adapted to connect to the lancet assembly; and
a damping ring adapted to engage the lancet assembly as the lancet assembly moves from the puncture position back towards the resting position to reduce movement of the lancet assembly back towards the puncture position.

Abstract
A lancing device comprises a main housing, a movable housing, and a damping ring. The main housing forming an inner aperture that encloses a portion of a lancet assembly. The lancet assembly has a lancet body, a lancet-plunger housing, and a lance. The lancet assembly is adapted to move between a resting position, a cocking position, and a puncture position. The movable housing is adjacent to the main housing. The moveable housing is adapted to move from a resting position to a cocking position. The moveable housing is adapted to connect to the lancet assembly. The damping ring is adapted to engage the lancet assembly as the lancet assembly moves from the puncture position back towards the resting position to reduce movement of the lancet assembly back towards the puncture position.

8. A lancet assembly adapted to move between a resting position, a cocking position, and a puncture position, the lancet assembly comprising:
-
a lancet body adapted to move within a lancing device; a lancet-plunger housing; a lance connected to the lancet-plunger housing and being adapted to puncture the skin of a user; a spring adapted to connect the lancet-plunger housing to the lancet body; and a damping ring adapted to engage the lancet-plunger housing as the lancet-plunger housing moves from the puncture position back towards the resting position to reduce movement of the lancet-plunger housing back towards the puncture position. - View Dependent Claims (9, 10, 11, 12, 13)

14. A lancing device comprising:
-
a main housing forming an inner aperture enclosing a portion of a lancet assembly, the lancet assembly having a lancet body, a lancet-plunger housing, and a lance, the lancet assembly being adapted to move between a resting position, a cocking position, and a puncture position; a moveable housing adjacent the main housing, the moveable housing being adapted to move from a resting position to a cocking position, and being adapted to connect to the lancet assembly; a first spring adapted to connect to the main housing and the lancet body, the first spring being generally wrapped around a shaft portion of the lancet assembly, the first spring being compressed as the moveable housing is moved from the resting position to the cocking position, the first spring returning to a resting position as the moveable housing returns to the resting position; a second spring adapted to connect the lancet body and the lancet-plunger housing, the second spring extending as the lancet assembly moves from the cocking position to the puncture position, the second spring returning to a resting position as the lancet-plunger housing moves from the puncture position back towards the resting position; and a damping ring adapted to engage the lancet assembly as the lancet assembly moves from the puncture position back towards the resting position to reduce movement of the lancet assembly back towards the puncture position. - View Dependent Claims (15, 16, 17, 18)
