Abstract:
An inflation control system comprising:a movable drive device having a drive arm that moves in longitudinal directions in response to drive signals;a syringe assembly comprising:a syringe barrel having a volume and a plunger opening at a proximal end and an output at a distal end;a fluid tube in fluid communication with the barrel volume through the output;a plunger movably disposed in the plunger opening and in the barrel for altering the volume by means of its position in the barrel, the plunger having a drive retainer at a proximal end, the retainer permitting the drive arm to automatically engage the retainer from one direction and after engaging, securing the plunger to the drive arm so that the plunger moves with the drive arm in longitudinal directions;a pressure sensor producing a signal representative of the pressure within said fluid line;a mounting bracket for engaging said syringe assembly and maintaining said syringe assembly in a stationary position in relation to the drive arm;a processor that provides drive signals to the drive device to automatically move the drive arm into engagement with the plunger retainer.
