Abstract
A lancet for acquiring a blood sample includes a unitary member which is hollow along at least a portion of its length. Preferably, the unitary member is in the form of a seamless cylindrical tube which is constructed out of a rigid and durable material, such as stainless steel. During the lancet manufacturing process, a series of individual grinding processes are performed on one end of the unitary member to yield a lancet which includes a plurality of skin-penetrable tips. In one embodiment, one end of the unitary member is subjected to a pair of single angle planar grinds to yield a lancet which includes a pair of sharpened tips. In another embodiment, one end of the unitary member is subjected to four compound angle planar grinds to yield a lancet which includes a pair of sharpened tips. In another embodiment, one end of the unitary member is subjected to three single angle planar grinds to yield a lancet which includes three equidistantly spaced sharpened tips.
