Abstract: A medical injection system is provided. The medical injection system includes an injection initiation feedback module. The injection initiation feedback module includes an actuator and a click collar, which comprise an impact plate and a click surface, respectively. The click collar further includes a click surface protrusion to restrict the click surface from contacting the impact plate. The actuator further includes an impact plate groove to accommodate the click surface protrusion at the initiation of injection and the click surface contacts the impact plate to generate an injection initiation feedback prompt.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention discloses an electronic device charger, mainly comprising: a voltage converting module, a microprocessor, a low voltage detecting unit, and an over voltage sensing unit. When a rated output voltage of a vehicle battery of an electric vehicle is detected to be lower than a first threshold voltage by the low voltage detecting unit or found to be higher than a second threshold voltage by the over voltage sensing unit, the microprocessor immediately stops the vehicle battery providing electrical power to at least one portable electronic device owned by the driver of the electric vehicle. Therefore, the electronic device charger can not only save the energy of the vehicle battery while the vehicle battery is at a low voltage state, but also protect the portable electronic devices from being damaged by the electrical power as the rated output voltage of the vehicle battery exceed a normal voltage level.
