Abstract: The invention relates to a method and device for withdrawing biological samples. The device has a receptacle which can receive one or several covers for sample containers, another receptacle which can receive one or several sample containers, and a mechanism. Said mechanism joins the covers and containers together during a working cycle in which the biological sample is withdrawn either through the cover or the sample container to a test capsule.

Abstract: In one embodiment of the present invention, a temperature sensitive tip switch comprises a first conductive arm, a second conductive arm disposed in a parallel, spaced apart relation beneath the first conductive arm, a third conductive arm disposed in a parallel relation beneath the second conductive arm, and a temperature sensitive actuator blade disposed in a parallel, spaced apart relation beneath the third conductive arm. The second conductive arm includes a cut-out portion which is capable of downward flexion and the third conductive arm includes a cut-out portion which is capable of downward flexion and which is engaged with the cut-out portion in the second conductive arm. A first pair of normally closed, electrical contacts are mounted on the actuator blade and the third conductive arm. A second pair of normally closed, electrical contacts are mounted on the second conductive arm and the first conductive arm.
