Abstract: In a mixing tip of an impression material cartridge, a top connective plate is on the center of the top of a pair of cylinders, with an impression material cartridge installed with the connecting end of each of a pair of mixing tips facing each other located on each side of the top connective plate, and a mixing screw inserted into a protruding mixing tube on the center of the upper part, with a connective structure of the mixing tips having protruding connecting wings on the lower side of the supporting structure, formed to achieve diagonal symmetry of a rotational bump on the end surface of the connecting wings on a lower supporting side of the mixing tips, and on the lower surface of the rotational bump, cylindrical guide pins that guide the connecting direction of the mixing tips are each formed to protrude towards the bottom.

Abstract: A squeezing gun for two-part medical viscous fluid that simultaneously squeezes two different kinds of medical viscous fluid contained in a double cartridge including two tubes containing the respective different kinds of fluids. Two horizontal scroll bars are moved horizontally to actuate the squeezing of the fluids and are driven by a driving motor.

Abstract: This invention is about squeezing gun for two-part medical viscous fluid that squeezes two different kinds of medical viscous fluid simultaneously that are contained in double cartridge where two tubes are combined in one body and when explained in more detail, this invention is to squeeze simultaneously two kinds of medical viscous fluid that are contained in double cartridge while two horizontal scroll bars are moving horizontally as driving power of driving motor is being reduced when push button of squeezing gun which has the shape of pistol is pressed.
