Applicator and electro-mechanical applicator drive system

摘要

An applicator (10) and an electro-mechanical applicator drive system (50) for automatically emptying the liquid components from respective syringes (60,61) in a controlled manner for co-applying fibrin sealant components with a gas to form a spray. The applicator drive system (50) includes a piston elevator section (600) which moves the syringe pistons of the respective syringes (60,61) in unison. The applicator drive system (50) further includes at least one syringe piston force sensor (602,602') which senses a force required by the piston elevator section (600) to move at least one of the syringe pistons forward and outputs a force sensor signal. A controller is provided which controls movement of a piston elevator of the piston elevator section based on the force sensor signal. <IMAGE>
