摘要：
A miniature portable multifunctional infusion device comprises a liquid bottle (4) and a film box body (16) fixedly arranged on a support frame (1). A directional input interface (17) and a directional output interface (14) that are communicated with an infusion bottle (4) and a needle head by using an infusion pipe are separately formed on the film box body (16). An elastic film (27) is arranged on the film box body (16), and a transmission system (31) is arranged at one side of the elastic film (27). The transmission system (31) comprises a miniature direct current motor (32) connected with a frequency adjusting system (28). The miniature direct current motor (32) is connected with a spiral straightening device (34) by using a speed reducer (33), and the spiral straightening device (34) is connected with a reciprocating film propping device (36) by using a two-order shaft (43). A truncated cone body (39) of the front end portion of the reciprocating film propping device (36) is in contact with the elastic film (27). In the infusion device, the miniature direct current motor (32) drives the transmission system (31), so that the reciprocating film propping device (36) moves, which implements conversion from electric energy to mechanical energy； in addition, the reciprocating film propping device (36) compresses the film box body (16) to change the volume of the film box body (16), so that an infusion speed is adjusted and controlled.L'invention concerne un dispositif de perfusion multifonctionnel portable miniature comprenant un flacon de liquide (4) et un corps de boîtier de film (16) agencé de façon fixe sur un cadre de support (1). Une interface d'entrée directionnelle (17) et une interface de sortie directionnelle (14) qui sont en communication avec un flacon de perfusion (4) et une tête d'aiguille en utilisant un tuyau de perfusion sont formées séparément sur le corps de boîtier de film (16). Un film élastique (27) est agencé sur le corps de boîtier de fixation
