20140023986 | MOTORIZED SYRINGE FOR USE WITH TWO TYPES OF DENTAL ANESTHETIC SOLUTION-CONTAINING CARTRIDGES - A motorized syringe for use with two types of dental anesthetic solution-filled cartridges, having a plunger plug in the 1.8 ml cartridge pushed by a push rod by a length required to push a plunger plug in the 1.0 ml cartridge. The syringe includes a cartridge holder for use with 1.0 ml and 1.8 ml cartridges, the push rod having a 1.0 ml position and a 1.8 ml position drawn back from the 1.0 ml position so that push rod movement can end at a common terminal position for both, a sleeve adapted to receive the push rod rear end when pushed back from the common terminal position, and to be not interfered with by the push rod's rear end when it is in the 1.0 ml position, the sleeve being pushed rearward with the push rod's rear end when pushed back to the 1.8 ml position. | 01-23-2014 |
20120088206 | LINEARLY MOTORIZED DENTAL SYRINGE - A linear cartridge-type motorized dental syringe has a plunger rod aligned with a drive shaft of a motor, the externally threaded plunger rod movable longitudinally, but not rotatably, relative to the casing, a cylindrical body rotated by the shaft, a nut having arm-like nut halves with internal threads engaging external threads on the rod, a locking ring for rotation around an axis of the rod and for longitudinal movement between a rearward position where the ring forces the threads on the nut halves to engage the threads on the rod, and forward where the ring releases engagement of the threads, pusher pins for moving the ring rearward when the cartridge holder is inserted, and a spring for pushing the locking ring back to the forward position, with rotation of the cylinder body resulting in rotative motion of the nut around the rod to move it forward. | 04-12-2012 |
