摘要:
An injection device is provided for delivering liquid compositions, such as viscous hyaluronic acid gels. The injection device includes a generally elongated housing having first and second ends. The housing is configured to receive an exchangeable cartridge having the liquid composition. The cartridge is received proximal to the first end of the housing. A drive mechanism is arranged within the housing and includes an electric motor and a power source, typically a rechargeable battery. The motor is coupled to a plunger rod which acts on the cartridge received in the housing to expel the liquid composition contained in the cartridge. A first actuation device for actuating the drive mechanism is provided on an upper side of the housing proximal to the first end of the housing, and a second actuation device for actuating the drive mechanism is provided at the second end of the housing.
