摘要： A medical injection system is provided. The medical injection system includes a cartridge module and an injection module accommodating the cartridge module. The cartridge module includes a plunger. The plunger includes a plunger recess and is configured move in an axial direction of the medical injection system. The injection module includes an actuator, a starter, and a needle cover. The actuator includes one or more upper elastic pieces which are compressed inward against the plunger recess, and one or more rotating chutes which the starter rotates along. The starter includes an inner annular surface which compresses the one or more upper elastic pieces inward. The one or more upper elastic pieces are no longer compressed inward by the inner annular surface when one or more accommodating space located on the inner annular surface are rotated to align with the one or more upper elastic pieces to trigger the injection.

摘要： A medical injection system is provided. The medical injection system comprises an injection module and the cartridge module coupled to the injection module. The injection module comprises a lead screw movable along an axial line into the cartridge module; a driver sleeve configured to partially accommodate the lead screw and to have a first sleeve end facing a distal end and having sleeve teeth, a dose plate including a first plate end facing the distal end, a second plate end facing a proximal end and having plate teeth corresponding to sleeve teeth, and a side surface located between the first plate end and the second plate end and having a surface tooth; and an indicia tube configured to accommodate the driver sleeve and the dose plate and to have tube concaves near a first tube end facing the distal end. The surface tooth corresponds to one of the tube concaves.

摘要： A medical injection system comprising an injection module, a retract module, and a bi-directional dose setting module. The bi-directional dose setting module comprises a dose plate, and the injection module comprises a dose knob engaged with the dose plate. The medical injection system generates a first response when the dose knob is rotated in the first direction, and generates a second response when the dose knob is rotated in the second direction.
