Self activated finger lancet
First Claim
1. A self-activated blood drop generator device comprising:
- casing means having an internal hollow;
blade means disposed within said hollow of said casing means for generating an incision in a patient'"'"'s skin, wherein upon the activation of said device, said blade means follows a predetermined path which causes a cutting portion of said blade means to travel out of said hollow of said casing means through an aperture defined in an end of said casing means to incise the patient'"'"'s skin and then retract back through said aperture into said hollow of said casing means;
fork means coupled to said blade means for propelling said blade means through said predetermined path;
cam means associated with said casing means for causing said cutting portion of said blade means to travel through an arcuate scalpel-like path as said cutting portion of said blade means passes through said aperture in said casing means, wherein said cam means includes a cam groove defined in an interior surface of said casing means and a cam groove follower defined on said blade means that rides in said cam groove; and
retractor means associated with said casing means, said blade means and said fork means for retracting said cutting means of said blade means into said hollow of said casing means.

Abstract
A self-activated blood drop generator device comprising a casing having an internal hollow and blade assembly disposed within the hollow of the casing for generating an incision in a patient'"'"'s skin. The device includes a fork-shaped triggering mechanism coupled to the blade assembly for propelling the blade assembly through a predetermined path. A cam arrangement associated with the casing causes the cutting portion of the blade assembly to travel through an arcuate scapel-like path as the cutting portion passes through an aperture in the casing. A retractor arrangement associated with the casing, the blade assembly and the triggering mechanism, are provided for retracting the blade assembly into the hollow of the casing. Also provided is accelerator arrangement associated with the casing and the triggering mechanism for accelerating the triggering mechanism through the hollow of the casing thereby causing the blade assembly to accelerate through the predetermined path. The activation of the device causes the cutting portion of the blade to travel out of the hollow of the casing through the aperture to incise the patient'"'"'s skin and then retract back through the aperture into the hollow of the casing.

10. A self-activated blood drop generator device comprising:
-
a casing having an internal hollow; a blade assembly disposed within said hollow of said casing for generating an incision in a patient'"'"'s skin, wherein upon the activation of said device, said blade assembly follows a predetermined path which causes a blade encased in said blade assembly to travel out of said hollow of said casing through an aperture defined in an end of said casing to incise the patient'"'"'s skin and then retract back through said aperture into said hollow of said casing; triggering means for propelling said blade assembly through said stroke, said triggering means including fork means for coupling said triggering means to said blade assembly; accelerator means associated with said casing and said fork means for accelerating said triggering means through said hollow of said casing thereby causing said blade assembly to accelerate through said predetermined path, wherein said accelerator means includes at least one C-shaped projection extending into said hollow from said casing that cooperates with said fork means to create an opposing force that accelerates the triggering means through said hollow of said casing; cam means associated with said casing for causing said blade to travel through an arcuate scalpel-like path as said blade means passes through said aperture in said casing; and retractor means associated with said casing, said blade assembly, and said fork means for retracting said blade into said hollow of said casing. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A self-activated blood drop generator device comprising:
-
casing means having an internal hollow; blade means disposed within said hollow of said casing means for generating an incision in a patient'"'"'s skin, said blade means having a cam groove follower; and a cam groove defined in an interior surface of said casing means, wherein said cam groove follower rides in said cam groove and causes said blade means to travel through an arcuate scalpel-like path when generating the incision in the patient'"'"'s skin.
