    摘要： A liquid dispensing pump (10) comprises: a first liquid storage cylinder (11), a second liquid storage cylinder (12), a first plunger (13) movably connected to the first liquid storage cylinder (11), a second plunger (14) movably connected to the second liquid storage cylinder (12), and a drive assembly (15) connected to the first plunger (13) and the second plunger (14). The first liquid storage cylinder (11) is provided with a first liquid entry and exit port (111). The second liquid storage cylinder (12) is provided with a second liquid entry and exit port (121). One end of the first plunger (13) is inserted into an internal cavity of the first liquid storage cylinder (11). One end of the second plunger (14) is inserted into an internal cavity of the second liquid storage cylinder (12). Further provided is a liquid dispensing device (100). The advantageous effect of the invention is: during each linear reciprocating movement cycle of the first plunger (13) and the second plunger (14), the first liquid storage cylinder (11) and the second liquid storage cylinder (12) discharge corresponding ingredients according to a pre-determined mixing ratio, and a mixed solution according to the pre-determined mixing ratio is obtained, thereby achieving precise mixing of different ingredients. In addition, the dispensing pump (10) discharges ingredients at a consistent ratio, thereby achieving uniform mixing without a dedicated mixer.

    摘要： Mixing device (1) and fluid mixing method, by means of successive transfers between syringes. The mixing method comprises placing a pair of syringes (2, 3) in the mixing device (1), adjusting a variable fixing element adaptable to the pair of syringes (2, 3) and selecting and running a mixing programme, being the mixing force, the speed and the range and the number of transfers adjustable. The mixing device comprises a mobile carriage (7) longitudinally movable and fixing elements (8, 9) with an adjustable distance between them. The invention allows for the mixing or emulsifying of blood fluids with different viscosity, particularly a protein gel and a platelet-rich plasma, for the preparation of dermatological formulations, in a versatile, hygienic and effective manner.
