12551629 · 2026-02-17 · ·

A syringe device and a syringe system with a syringe device provides an ergonomic syringe device which enables safe operation and safe injection by using a pen-like syringe device having a drive housing, a syringe receptacle for receiving a syringe having a syringe body and a plunger guided therein, and a manually operable push button for activating an electrical delivery unit. The drive housing has a pressure supply unit for pneumatically actuating the plunger and a coupling connection for connection to an external supply unit. The pressure supply unit includes a drive channel which can be connected to the plunger of an inserted syringe. The syringe device has a vent channel connected to the drive channel and via an opening to the environment, the opening being closable by a finger when the push button is actuated.
