Injection apparatus comprising a laterally attached actuation member for triggering the product release

A drive and metering apparatus for an injection apparatus for release of a liquid product, the drive and metering apparatus having a distal end where the liquid product is dispensed, and a proximal end, which is opposite the distal end, the drive and metering apparatus comprising:

• a) a housing extending along a lengthwise axis of the drive and metering apparatus;
• b) a dose setting member configured to rotate relative to the housing around the lengthwise axis for setting the product dose to be released;
• c) an actuation member configured to shift axially and non-rotatably relative to the housing along the lengthwise axis from an unactuated position, which it takes during the setting of the product dose to be released, to an actuated position, which it takes during product release, wherein shifting of the actuation member into the actuated position triggers the product release, and the actuation member comprises an actuation section to which a user of the drive and metering apparatus has access and by which the user can shift the actuation member from the unactuated position to the actuated position, and wherein the actuation section is disposed distal to the dose setting member;
• and
• d) a dose display member, wherein the dose display member, in the unactuated position of the actuation member, is coupled to the dose setting member such that a rotation of the dose setting member causes a rotation of the dose display member, and wherein the actuation member is coupled to the dose display member such that the dose display member is shifted axially and non-rotatably relative to the housing along the lengthwise axis by the actuation member when the actuation member is shifted from the unactuated position to the actuated position.
