FIELD: medicine.
SUBSTANCE: invention refers to medical equipment, namely to driving devices of an infusion apparatus. Drive device (1) comprises: pump drive made with possibility of its functional mechanical connection with dosing device (2) containing dosing cylinder (20) and piston (21) installed inside metering cylinder (20) on tight sliding fit, to control operation of dispenser (2), wherein the pump drive comprises piston rod (10) installed with the possibility of directed movement along the movement axis (X) and made with possibility of its functional mechanical connection to piston (21); locking device (11) comprising at least one locking element (110) movable between the locking configuration and the unlocking configuration, wherein in the unlocking configuration, at least one locking member (110) allows for the establishment and/or removal of the functional mechanical connection between the pump drive and dispenser (2), and in blocking configuration - prevents establishment and/or removal of functional mechanical connection between pump drive and metering device (2) due to mechanical interaction of one or more structural elements of locking element (110) with metering cylinder (20), wherein actuator (1) of the infusion apparatus is configured to control at least one locking member (110) such that it receives the unlocking configuration when the pump drive is in at least one predetermined configuration, and blocking configuration - when pump drive is in configuration, different from specified, wherein at least one predetermined configuration is a configuration in which piston rod (10) is in a predetermined position along axis (X) of its movement.
EFFECT: disclosed is a drive device of an infusion apparatus with a locking device.
