<p>The invention relates to an electropneumatic device meant for performing, preferably, a perfusion of medical liquids by using a disposable perfusion kit, in a hospital or an ambulance. According to the invention, the device consists of a body (1) that can be tightly closed by a lid (2), that can accommodate a bag containing the perfusion liquid and wherein there is installed an air pressure controlled by a proportional pneumatic regulator (3) coupled to a pressurized enclosure protected by a safety valve (4) that can be supplied by an electrocompressor (5) whose automatic operation is dictated by a pressure sensor (6), or, in emergency cases, supplied from the exterior, through a valve (7), within the body (1) there being placed a magnetic resonance flow meter (8) which, together with an electronic block (9) supplied from an electric battery (10), controls the flow of perfused liquid in the range of the preset value, by controlling the control current applied to the regulator (3) which adjusts the required output pressure correspondingly.</p> |
