Abstract
The syringe pump comprises a receiving position for a syringe. The piston plate of the syringe is moved by a drive head which is fastened to a drive rod. For locking the piston rod prior to fixing the piston plate in the drive head, a braking element is provided on a syringe holding head. The syringe holding head further serves for determining the respective syringe size. After placing the syringe holding head against a syringe cylinder, the brake element is actuated to temporarily engage the piston rod and fix it relatively to the syringe cylinder.
Claims12
Syringe pump having a piston brake, comprising a syringe holder for holding a syringe cylinder (11) of a syringe (10) inserted in a syringe position (P), a drive head (16) engaging a piston plate (14) of the syringe (10), the drive head (16) being carried by a drive rod (17) extending parallel to the inserted syringe, and a brake element (33) movable, transversely to the longitudinal direction of the syringe, toward the piston rod (12),
- wherein the brake element (33) is arranged on the side of the syringe position (P) opposite the drive rod (17) and is pressed toward a syringe bearing (15) arranged on the drive rod (17) side.
