Driving device and drug infusion device

Abstract

The invention discloses a drug infusion device. The drug infusion device comprises a drug storage unit, a piston, a driving rod, a driving unit, a position detection region, a power unit and a controlunit, wherein the driving rod is connected with the piston, and can push the piston to move; the driving unit includes a driving part and a positioning part, and through movement in different directions, the driving unit drives a driving part and a positioning part to move; the positioning part interacts with the position detection region at different positions, so as to trigger different position signals; the power unit is connected with the driving unit, and the power unit applies force to the driving unit to make the driving unit to move; and the control unit is connected with the power unit, and controls the force application direction of the power unit according to the position signals, so that the driving unit moves in multiple ranges with different widths, so as to implement the driving effect of different strokes on the driving rod, and different and selectable infusion modes are formed. Multiple infusion modes improve the infusion flexibility and the infusion efficiency.

Description

technical field [0001] The invention mainly relates to the field of medical devices, in particular to a driving device and a medicine infusion device. Background technique [0002] A drug infusion device is a medical device that achieves the purpose of disease treatment by continuously injecting drugs into the patient's body. The drug infusion device is widely used in the treatment of diabetes. It continuously infuses insulin into the patient's skin according to the dose required by the human body, so as to simulate the secretory function of the pancreas, so as to maintain the stability of the patient's blood sugar. The drug fluid is usually stored inside the infusion pump body. In existing drug infusion devices, the pump body is usually pasted directly on the patient's body through medical adhesive tape, and the patient operates the remote device for infusion. [0003] During drug infusion, the infusion mode of the existing infusion equipment cannot change the infusion ste...

AI Technical Summary

Problems solved by technology

[0003] When performing drug infusion, the infusion mode of the existing infusion equipment cannot change the infusion step length (unit infusion volume) of the equipment, the adjustment of infusion volume and infusion rate is very limited, and the infusion process cannot be flexibly controlled , the infusion efficiency is relatively low

Too large or too small drug infusion will cause the patient's body fluid level to fluctuate greatly under the control of the infusion drug, which cannot achieve the goal of more precise control of body fluid level
