Bilaterally driven intelligent control infusion device

A bilaterally driven intelligent control infusion device, comprising:

• an infusion unit, the infusion unit comprises a drug storage unit, a piston and a rigid screw, the piston is arranged in the drug storage unit, a metal piece arranged on the piston, fixedly connected to the rigid screw;
• a driving wheel, provided with wheel teeth, drives the rigid screw to move by rotation, the rigid screw advances the piston to move;
• a driving unit cooperating with the driving wheel;
• a power unit, connected to the driving unit, outputs forces in two different directions on the driving unit to lead the driving unit to pivot;
• a position detector, interacting with the metal piece to generate a signal;
• a program unit, connected to the infusion unit, converts the signal into a position information of the piston and controls the driving unit to operate with a different infusion rate according to requirements,
• wherein the program unit controls the driving unit to perform a multiple-mode operation, making the infusion device have multiple infusion increments or infusion rates,
• wherein the multiple-mode operation of the driving unit includes multiple different movement amplitudes and multiple different movement rates in a unit time, wherein the multiple different movement amplitudes include controlling a magnitude of a current of the power unit by the program unit to rotate the driving unit in a first direction to a first position or controlling the magnitude of the current of the power unit by the program unit to rotate the driving unit in the first direction to a second position, wherein the first position is different from the second position.
