Blood lancet
| Details |
Inventors: Beiter, Werner;
Assignee:
Primary Examiner:
Assistant Examiner:
Attorney, Agent or Firm:
In a blood lancet consisting of a handle and a tip, which are injection molded in one piece of plastic, there is provided according to the invention a protective yoke which protects the tip against damage. The protective yoke (24) is integrally molded to the handle in one piece, leaving predetermined break points, so that it can be broken off. The tip of rhombic cross-section comprises a base which imparts mechanical stability and limits the pricking depth, and an offset fine pricking tip. |
|
DETAILED DESCRIPTION I claim: 1.
A relatively flat blood lancet, having a handle portion and a tip portion having sharp edges, which portions are made of plastic in one piece, comprising: a flat protective yoke-like guard integrally formed as a part of said one piece of plastic, and said protective yoke-like guard being attached at two weakened breakoff points to said handle only on opposite sides of said tip but free of any contact therewith, with said tip being received unobstructedly in a cutout-like recess form transversely of said protective yoke-like guard; and said tip being spaced away so as to be free from said protective yoke-like guard, thereby leaving the sharp edges of said tip free and clear of any plastic material, and said two weakened breakoff attachment points of said protective yoke-like guard adapted to be broken off by bending said protective yoke-like guard in a direction perpendicular to a plane passing through said blood lancet.
2.
The blood lancet according to claim 1, wherein the two weakened breakoff attachment points of the said protective yoke-like guard on the opposite sides of said tip are formed as predetermined break points.
3.
The blood lancet according to claim 1, wherein said tip has a cross-section which is elongated in one of its transverse axis and which widens toward the center of the cross-section in the direction of the other transverse axis normal to the former.
4.
The blood lancet according to claim 3, wherein said tip is rhombic in cross-section and has sharp lateral side edges.
5.
The blood lancet according to claim 3, wherein said tip has a base of large pyramidal angle and an offset pricking tip of a smaller pyramidal angle.
6.
The blood lancet according to claims 3 or 5, wherein said handle and said protective yoke-like guard have essentially the same flat cross-section, and their thickness corresponds to the minor diagonal of the rhombic base area of said tip.
7.
The blood lancet according to claim 6, wherein the distance between said tip and said protective yoke-like guard is smaller than the thickness of the protective yoke-like guard
