The utility model relates to the technical field of medicament mixing assistors, and discloses a double-component medicament opposite-
extrusion mixing assistor which comprises a transverse plate, a transverse plate and a transverse plate, the two fixed seats are oppositely mounted on two sides of one end of the transverse plate; the
extrusion roller is rotationally mounted between the two fixed seats through a rotating shaft; the clamping groove is formed in the outer wall of the
extrusion roller in the axial direction of the extrusion roller; and the pressing mechanism is arranged in the clamping groove and used for pressing the bag
tail in the clamping groove. According to the double-component medicament opposite-extrusion mixing assist device, the
tail part of a medicament bag is fixed in the clamping groove, and when the extrusion roller rotates, the extrusion force generated when the bottom of the medicament bag penetrates through a gap between the extrusion roller and the transverse plate is utilized, so that the medicament bag can be uniformly extruded, time and labor are saved, and the mixing efficiency of the double-component medicament is improved.
