A pen-like syringe system comprising:

• a syringe holder for accommodating a syringe having a syringe barrel and a plunger movably guided in the syringe barrel;
• a drive housing connected to the syringe holder;
• an electric delivery device operated by an integrated power supply arranged in the drive housing for pneumatic operation of the plunger of the syringe inserted into the syringe holder with positive or negative pressure;
• a drive channel connecting the electric delivery device to the plunger of the syringe inserted into the syringe holder;
• and
• a button arranged on the syringe system for operation of the electric delivery device,
• wherein the syringe system has a vent channel with a first end that is connected to the drive channel and a second end that is connected to the surroundings via an opening, the opening being closeable during activation of the button,
• wherein the button is configured to be activated with a finger of a user and the delivery device is configured to be activated upon activating the button,
• wherein the opening is configured, dimensioned, and arranged with respect to the button such that the opening is automatically closed by the finger when the button is activated, and
• wherein the opening is opened towards the surroundings when the button is released, and the drive channel is configured to be vented to the surroundings and to stop subjecting the plunger of the syringe inserted into the syringe holder to positive or negative pressure upon releasing the button.
