Abstract: A terminal assembly is disclosed. The terminal assembly comprises a main body having a welding platform and a first electrical conductive member having a connection terminal. According to the present invention, a welded structure is formed between the main body and the first electrical conductive member by making the connection terminal be welded on the welding platform. Briefly speaking, when utilizing this terminal assembly to make two electrical nodes be electrically connected to each other, one electrical conductive end of the main body and the first electrical conductive member are firstly connected to the two electrical nodes, respectively. Next, a welding process is applied to the welding platform and the connection terminal, such that an electrical connection is therefore established between the two electrical nodes.

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.
