  • Publication number: 20060278225
    Abstract: The present invention relates to a manually actuated delivery device for the delivery of a dose of liquid comprising a housing (1) which includes an outlet through which liquid, in use, is delivered. An actuating member (2) is moveably disposed relative to the housing (1) between a first position and a second position, the user moving the actuating member (2) into the second position to actuate the delivery device. A liquid delivery assembly (3) is located at least partly within the housing (1) the liquid delivery assembly (3) comprising a liquid delivery unit (4) a carrier unit (5) for the liquid delivery unit (4) and a coupling member (6) which couples the movement of the actuating member (2) and the carrier unit (5). The movement of the carrier unit (5) activates a counting mechanism (7a, 7b) which indicates how many doses have been delivered.
