摘要： An exchangeable cartridge for an injection device is disclosed. The cartridge (3) comprises a container (4) and a plunger (10) connectable with a plunger rod (9). The container receives the plunger rod from its rear end. The plunger comprises a rod connector (12) connectable with a front portion (13), and the rod connector has a base portion (24), an outer wall section (15), an inner wall section (16), and a rod stop portion (17) encircled by the inner wall section. The inner wall section comprises several tongues (22) protruding rearwards from the base portion and defining an entrance opening (18) for the plunger rod. The inner wall section receives a front portion (13) of the plunger rod through the entrance, and the tongues are provided with retaining portions arranged to retain the front end portion during retraction of the plunger rod within the housing.

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.

摘要： A needle device including a housing. The housing includes a first housing element provided towards a proximal end of said needle device and a second housing element provided towards a distal end of said needle device. A cutting element having a sharp proximal end is arranged at a proximal end of said first housing element. A cannula having a blunt proximal end is fitted to the second housing element and an opening for the cannula is provided at the proximal end of the first housing element. The first housing element and the second housing element are moveable relative to each other between an extended position where the proximal end of the cannula does not extend beyond the proximal end of the cutting element and a compressed position where the cannula extends through the opening of the first housing element and past the proximal end of the cutting element.
