Abstract:
1. A lancet for skin pricking, comprising: an elongate tubular plastic body of a first plastic material, the body having a forward end and a rearward end, and an interior surface defining a first tubular region; and a hollow plastic insert of a second plastic material, the first plastic material being different from the second plastic material, the plastic insert being molded to form a monolithic structure comprising a second tubular region that defines a hollow cylindrical rear portion, a closed forward end, and an integral sharp tip at the closed forward end, the plastic insert located within the body and with the integral sharp tip projecting through said forward end of the body, the body being molded over the insert such that: the forward end of the body is closed by an end wall, with the sharp tip of said insert projecting from a forward surface of the end wall, and a rear surface of the end wall abuts the closed forward end of the insert, blocking forward movement of the insert relative to the body; and the body forms an interior shoulder within the first tubular region which abuts the cylindrical rear portion of the insert, blocking rearward movement of the insert relative to the body, thereby affixing the insert within the body, wherein, the plastic insert is immovable relative to the body, the second plastic material forming the plastic insert is a liquid crystal polymer, and the first tubular region and the second tubular region together define a tubular passage closed at said forward end.
