Unilaterally driven drug infusion system

A unilaterally driven drug infusion system, comprising:

• an infusion unit, comprising:
• a reservoir, a piston and a screw, wherein the piston, connected with the screw, is arranged in the reservoir;
• a driving unit including at least one rotating shaft and at least one driving member, wherein the at least one driving member includes at least one driving end, and the driving member rotates around the rotating shaft to advance or reset the driving end;
• at least one driving wheel provided with wheel teeth, wherein the driving end which is advancing pushes the wheel teeth to rotate the driving wheel, thereby driving the screw forward;
• a linear actuator and a reset unit respectively connected to the driving member, wherein the linear actuator and the reset unit apply driving power to the driving member to advance and reset the driving end, respectively;
• a control unit, wherein the control unit is connected to the linear actuator or the reset unit, controls the linear actuator or the reset unit to apply different driving powers on the driving member;
• and
• a sensing unit operatively connected to the control unit and used to sense or recognize body movements, wherein the body movements which are different represent different functional instructions, and according to the body movement sensed or recognized by the sensing unit, the control unit controls the infusion unit to execute a corresponding functional instruction of the functional instructions,
• wherein the rotating shaft and the reset unit are disposed on a base, a position of the driving end is fixed relative to the driving member, and the linear actuator deforms and shrinks to provide the driving power to the driving member after the linear actuator is energized.
