Abstract: A retractable sharps assembly comprising a housing and a sharps unit. The housing comprises first and second open ends and a shoulder proximate the first end. The sharps unit generally comprises a frame, a shelf having a sharps member extending therefrom positioned in the frame, and at least one elastic member extending between the shelf and the forward end. As the frame is inserted into and moved forward in the hollow housing, the shelf is retained by the shoulder such that the elastic member is loaded between the shelf and forward end. A trigger mechanism interacts with the shoulder and disengages the shelf. The load in the elastic member drives the sharps member towards the forward end and through the second end opening, and simultaneously compresses the elastic member. The elastic member thereafter relaxes to retract the sharps member within the housing.

Abstract: A lancet assembly having a lancet holder and a triggler enclosing a lancet structure. The triggler is partially inserted into a lancet holder from the distal end. The holder is provided with a rigid internal spring holder to receive the spring-loaded lancet structure. The lancet structure is provided with a body coupled to a spring which extend from the proximal end of the body. The spring has a linear axis of compression which coincide with the longitudinal axis of the lancet assembly. A lancet is attached to the body with the sharp tip pointing towards the distal end. The triggler interacts with the lancet holder via a triggering element to maintain the spring in a compressed state such that the lancet structure is in a stable standby position which is not easily triggered by accidental bumps on the assembly.
