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.
