In preparation of an emulsion by causing a mixture to flow from one syringe through a connector into another syringe, an object is to prevent the air from being entrained into cylinders and prepare the emulsion containing no air bubble, and another object is to easily prepare a homogeneous emulsion. Provided is a syringe pressing apparatus, including: a syringe fixing mechanism (20) for fixing two syringes (9) to a casing (10) , the two syringes (9) being coupled to each other through a connector (99) ; a pressing mechanism (40) for alternately pressing syringe plungers (91) of the two syringes (9); and a plunger-pressure-measuring device for measuring a pressure with which the pressing mechanism (40) presses the syringe plungers (91).

Dans une préparation démulsion effectuée en transférant un fluide mélangé dune seringue à une autre seringue par lintermédiaire dun connecteur, la présente invention concerne une technique pour préparer aisément un médicament en émulsion homogène sans génération de bulles dair en empêchant lair de sintroduire dans un cylindre. Un dispositif de pression de seringue comprend un mécanisme de fixation (20) pour fixer deux seringues (9) mutuellement raccordées au moyen dun connecteur (99) à un boîtier (10) et un mécanisme de pression (40) pour appuyer alternativement sur les pistons de seringue (91) desdites deux seringues (9). Le mécanisme de pression (40) est équipé dun dispositif de mesure de pression de piston pour mesurer la pression appliquée pour appuyer sur les pistons de seringue (91).
