A quick-insertion membrane pump-type infusion device, comprising a membrane-pump housing (6) provided with connectors (8, 4) for intake and discharge intake and discharge connectors (8, 4) are connected, by means of an infusion tube (2), to a liquid medicine bottle (17) and an infusion needle (1), respectively, and a liquid inlet locking valve (9) and a liquid outlet one-way valve (5) are arranged on the intake and discharge connectors (8, 4) arranged on the outside of the membrane-pump housing (6) is a flexible silicon membrane (3) arranged on the outside of the silicon membrane (3) is a frustum-shaped trigger head (13) in contact with the flexible silicon membrane (3) a flow guide baffle (10) is also arranged on the rear end of the liquid outlet one-way valve (5) located inside the membrane-pump cavity (7) of the membrane-pump housing (6) one end of the flow guide baffle (10) and the inside wall of the membrane-pump housing (6) form an air-collecting chamber the other end of the flow guide baffle (10) and the inside wall of the membrane-pump housing (6) form an exhaust duct (15). The quick-insertion membrane pump-type infusion device, under the effect of the reciprocating action of the frustum-shaped trigger head (13) on the flexible silicon membrane (3), changes the volume of the cavity, actuating the liquid inlet locking valve (9) to close and the liquid outlet one-way valve (5) to open, causing a liquid to be directed to flow into a blood vessel in step with the shifting frequency of the reciprocation sequence, the process of infusing a liquid is accomplished.Linvention concerne un dispositif de perfusion à soufflet à insertion rapide, comprenant un boîtier de soufflet (6) pourvu de connecteurs (8, 4) pour lentrée et la sortie les connecteurs dentrée et de sortie (8, 4) sont connectés au moyen dun tube de perfusion (2) à un flacon de médicament liquide (17) et une aiguille de perfusion (1) respectivement, et une valve de verrouillage dentrée de liquide (9) et u
