INFUSION PUMP FOR THE DOSED ADMINISTRATION OF A MEDICINAL LIQUID

摘要

Infusion pump comprises a bottle (7) of infusion solution with a piston (6) which forms its base and is biased along it by a spring (5) or pneumatic system. A valve (10) controls the dispensing of infusion solution. The piston system is not linked to the valve, so that solution under pressure is constantly present in the inlet (9) immediately in front of the valve. Independent claims are included for: (a) a method for controlling dispensing of infusion solution using the pump; (b) a control program for use in the method (no details given); and (c) a semiconductor in which the program is stored (no details given).
