Abstract
A blood sampling device (1) comprising a housing (10) and a lancet (50). The housing has a fixed abutment surface for holdingly engaging the lancet in a rearward primed position. The blood sampling device further comprises a trigger (22) moveable from a rest position to a fire position to release the lancet for forward movement, wherein the trigger deflects the lancet body in a direction generally transverse to the longitudinal axis of the housing such that the lancet body may move forwardly past the fixed abutment surface.
Claims20
A blood sampling device comprising:
- a housing having a forward end with an opening therein;
- a lancet comprising a lancet body having a first radial wing and a second, rigid radial wing, the lancet body supporting a lancet needle at a forward end thereof, the lancet being moveably mounted within said housing;
- an urging member for urging the lancet forwardly, in use, relative to the housing between a rearward primed position in which the lancet needle is within the housing and a forward lancing position in which a tip of the lancet needle projects forwardly from the opening at the forward end of the housing;
- wherein
- said housing defines a cavity, the cavity including a passageway along which the lancet travels between the rearward primed position and the forward lancing position and the housing having an abutment member extending into the cavity defining a fixed abutment surface for holdingly engaging a front surface of the first radial wing of the lancet in the rearward primed position;
- and
- the blood sampling device further comprising a trigger moveable from a rest position to a fire position to release the lancet for forward movement, wherein the trigger contacts the first radial wing to deflect the lancet body in a direction generally transverse to a longitudinal axis of the housing such that the entire lancet body rotates so that the first radial wing is no longer engaged with the fixed abutment surface allowing the lancet body to move forwardly past the fixed abutment surface;
- and
- the housing comprising a deflection surface positioned in and projecting into the passageway forwardly of the abutment surface, the deflection surface being configured to contact the second rigid radial wing to rotate the entire lancet, after release and after the lancet forwardly passes the fixed abutment surface.
