Abstract: The present invention provides a new structure for test plates to rapidly siphon and transfer the blood, consisting of an upper plate, a lower plate, and two electrode plates, and the features including: a convex arc-shaped press area located on the front of the upper plate, the said area has a sucking hole on the top for blood suction where can receive drop of blood from fingertip. There are several triangular lattices of air holes built inward and around the external periphery of the sucking hole, so that when a finger is placed on the press area to force air out to release pressure and then the air hole will close immediately thereafter. This device is helpful by sucking the blood with the vacuum principle so as to rapidly siphon and transfer the blood for blood test.
