Lancing device for one skin puncture
First Claim
1. A lancing device, comprising:
- a housing enclosing at least a portion of a lancet assembly, the lancet assembly having a lancet body, a lancet-plunger housing, a damping ring, and a lance, the lancet assembly being adapted to move between a resting position and a puncture position,wherein the lancet-plunger housing is adapted to engage the damping ring as the lancet assembly moves from the puncture position towards the resting position to reduce movement of the lancet assembly back towards the puncture position, the damping ring being directly coupled with an end surface of the lancet body, the lancet-plunger housing being spaced from the damping ring when the lancet assembly is in 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.

7. A lancet assembly adapted to move between a resting position and a puncture position, the lancet assembly comprising:
-
a lancet body adapted to move along a shaft in a lancing device; a lancet-plunger housing adapted to move along the shaft independently from the lancet body; a lance coupled to the lancet-plunger housing and being adapted to puncture the skin of a user; and a damping ring coupled with an end surface of the lancet body, the lancet-plunger housing being configured to engage the damping ring via an impact force as the lancet assembly moves from the puncture position towards the resting position to reduce movement of the lancet assembly back towards the puncture position, the lancet-plunger housing being spaced from the damping ring when the lancet assembly is in the puncture position. - View Dependent Claims (8, 9, 10, 11)

12. A method of using a lancing device, comprising:
-
providing a housing enclosing at least a portion of a lancet assembly, the lancet assembly having a lancet body, a lancet-plunger housing, a damping ring, and a lance; moving the lancing device from a cocking position towards a puncture position such that the lancet-plunger housing is spaced from the damping ring when the lancing device is in the puncture position; moving the lancing device from the puncture position towards a resting position; and as the lancing device moves from the puncture position towards the resting position, engaging the lancet-plunger housing with the damping ring to reduce movement of the lancing device back towards the puncture position. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
