Abstract
Abstract An improved collar lancet device having a lancet housing with an open first end and a plunger element contained within the housing such that a receiving end slides towards the open first end in such a manner as to be urged into a piercing orientation wherein the receiving end protrudes up to a maximum amount from the lancet housing upon triggered firing thereof. Further, the lancet device includes a disposable cap element including a lancet contained in a sheathed relation by a cap body structured for secure yet removable fitted engagement on the lancet housing, the lancet contained therein being structured for engagement within the receiving end of the plunger element such that when the plunger element moves to its piercing orientation a tip of a piercing member of the lancet protrudes from an aperture in the top end of the cap body before retracting to concealed orientation within the cap body. Further, the lancet and cap body are engaged with one another such that they cannot be removed from one another yet the lancet is able to slide relative to the cap body, and upon removal of the cap body from its fitted position atop the lancet housing the cap body will be locked into a sheathed orientation over the lancet, thereby preventing further repeated use of the used and possibly contaminated lancet contained therein.
