摘要
A dispensing device for dispensing at least two fluids comprises a housing (12,22) of a pistol-like configuration having an integral handle (50), in which a spring-biased trigger (60) is received. Within the housing (12,22) of the dispensing device (10), two syringes (80,81) are received and fixated, which syringes contain respective fluids to be accurately dispensed. Provided a cover (22) of the housing is closed, the motion of the trigger (60) relative to the handle (50) is transmitted to a toothed rack which cooperates with a propeller body (70) in a ratchet-like manner. The ratchet-like cooperation allows a uni-directional motion of the propeller body (70) and prevents a motion of the propeller body (70) in the opposite direction. Provided the cover (22) is not closed, the motion of the trigger (60) relative to the handle is not transmitted to the propeller body (70), and any unintentional dispensing of fluids from the dispensing device prior to the preparing of the dispensing device for use by closing the cover (22) is consequently prevented.
