Disposable-retractable finger stick device
First Claim
1. Apparatus for implementing a skin incision, comprising:
- a blade having a cutting edge;
housing means for housing said blade, said housing means having an exterior surface adapted to be placed flush against the skin and an elongated slot located on said exterior surface;
blade pivoting means, located within said housing means, for pivotally guiding said blade through said elongated slot, said blade pivoting means having a first and second end wherein said first end is pivotally coupled to said housing means and said second end supports said blade, whereby said cutting edge extends from a first surface of said second end toward said elongated slot, said second end having a sloped surface formed thereon opposite said first surface; and
actuatable depressing means, located within said housing means, for engaging and holding said blade pivoting means in a set position, preventing the pivotal movement of said blade pivoting means within said housing, said depressing means being actuated to disengage said blade pivoting means and transverse said sloped surface, displacing said second end of said blade pivoting means toward said elongated slot, such that said cutting edge of said blade emerges from said elongated slot and incises the skin.

Abstract
A finger stick device for making a skin incision includes a blade pivot arm having a first end pivotally coupled to a housing and a second end having an upper sloped surface and a lower surface. A blade is affixed to the second end such that its cutting edge extends away from the lower surface. A resilient bias member when actuated traverses the upper surface and depresses the second end of the blade pivot arm, such that the blade exits the housing and incises the skin. The incising operation is complete upon the bias member traversing the sloped upper surface of the blade pivot arm. Also disclosed herein is a method for manufacturing the finger stick device, in which the bias member and blade pivot arm are molded as a monolithic unit. A blade is attached to the blade pivot arm, and the blade and monolithic unit are inserted into the housing. Further disclosed is an embodiment in which the housing is formed of two uniformly shaped halves, which when joined, provide an internal space for the monolithic unit. In this manner, the two halves are joined with the monolithic unit aligned therebetween so that the housing appears as an integral unit.

23. Apparatus for implementing a skin incision, comprising:
-
a blade having a cutting edge; housing mean for housing said blade, said housing means having a surface adapted to be placed flush against the skin and an elongated slot on said surface; blade pivoting means, located within said housing means, for pivotally guiding said blade through said elongated slot, said blade pivoting means having a first and second end wherein said first end is pivotally coupled to said housing means and said second end supports said blade, whereby said cutting edge extends from a first surface of said second end toward said elongated slot, said second end having a sloped surface formed thereon, opposite said first surface; actuatable depressing means, located within said housing means, and when actuated enabling said depressing means to traverse said sloped surface, displacing said second end of said blade pivoting means toward said elongated slot, such that said cutting edge of said blade emerges from said elongated slot and incises the skin; and retracting means, positioned on said blade pivoting means, for rapidly retracting said second end of said blade pivoting means when coacted by said depressing means immediately after traversing said sloped surface of said second end of said blade pivoting means such that said cutting edge of said blade is retracted from said elongated slot into said housing means.
