1. A bleeding time testing system comprising:
- a bleeding time tester comprising;
a body having a top surface and a bottom surface;
a cutting blade positioned in said body and movable between a first position within said body and a second position extending outwardly of said bottom surface of said body; and
a switch actuator positioned so as to extend outwardly of said body, said switch actuator being movable between a pre-actuating position and an actuating position, said switch actuator cooperative with said cutting blade so as to move said cutting blade from said first position to said second position when said switch actuator is in said actuating position; and
a tripper affixed onto said body of said bleeding time tester and cooperative with said switch actuator, said tripper comprising;
a housing mounted onto said body;
a slide frame slidably interconnected to said housing, said slide frame having a surface cooperative with said switch actuator of said bleeding time tester, said slide frame movable between a pre-activated position and an activated position, said slide frame extending in parallel relation to said bottom surface of said body; and
an actuator button mounted on said housing and cooperative with said slide frame, said actuator button movable between a pre-activating position and an activating position, said actuator button causing said slide frame to move in parallel relation to said bottom surface of said body to said activated position when said actuator button is moved to said activating position, said slide frame having an inverted U-shaped slot formed on a side thereof, said actuator button having a pin extending inwardly therefrom in parallel relation to said bottom surface of said body, said pin received within said slot when said slide frame is in said pre-activating position, said pin movable out of said slot so as to cause said slide frame to move to said activating position.

Abstract
A bleeding time testing system including a bleeding time tester having a cutting blade and a switch actuator, and a tripper affixed onto the body of the tester and cooperative with the switch actuator. The tripper includes a housing, a slide frame slidably interconnected to the housing and having a surface cooperative with the switch actuator, and an actuator button mounted on the housing and cooperative with the slide frame. The actuator button is positioned so as to cause the slide frame to move to the activated position when the actuator is moved downwardly. The actuator button is positioned directly above a centerline of the cutting blade of the tester.
