A novel infusion apparatus comprises a function portion (2) and a control portion (6), wherein the function portion (2) is provided with an introducing head (1) and a liquid storage chamber (3), the control portion (6) is provided with a battery (7) and a control circuit board (8) therein, and the introducing head (1) comprises a contact head (11), a liquid guide tube (12), a piezoelectric ceramic transducer (13) and a micro-pump (14). The micro-pump (14) provided in the ultrasonic infusion device pumps the liquid in the liquid storage device, and the liquid is precisely metered by the micro-pump (14) and delivered through a connection device to the liquid guide tube (12) so as to push through to the surface of the contact head (11). By using the principle of ultrasonic directional pressure application, the liquid is cavitated and atomized to form a vapor of small molecules, and skin cells are caused to vibrate therewith at the same time, providing a subtle massaging effect and changing the cell volume, thereby improving local circulation of blood and lymph, enhancing cell permeability and improving tissue metabolism and regeneration. As the device uses the micro-pump (14) to pump the liquid in the liquid storage device, the liquid does not need to contact hands or other media directly, thereby significantly increasing the utilization rate of the liquid.Un nouvel appareil de perfusion comprend une partie fonctionnelle (2) et une partie de commande (6), la partie fonctionnelle (2) étant pourvue d'une tête d'introduction (1) et d'une chambre de stockage de liquide (3), la partie de commande (6) étant pourvue d'une batterie (7) et d'une carte de circuit de commande (8) à l'intérieur de celle-ci, et la tête d'introduction (1) comprenant une tête de contact (11), un tube de guidage de liquide (12), un transducteur piézoélectrique en céramique (13) et une micro-pompe (14).
