Double-side-driven multi-infusion-mode medicine infusion device

Abstract

The invention discloses a double-side-driven multi-infusion-mode medicine infusion device. The double-side-driven multi-infusion-mode medicine infusion device comprises a medicine storage unit, a piston, a driving wheel, a driving unit and a power unit; the piston and the driving wheel are respectively connected with a screw rod; the driving wheel is provided with wheel teeth; the driving wheel pushes the screw rod to move through rotation; the piston is arranged in the medicine storage unit; the screw rod pushes the piston to move; the driving unit is matched with the driving wheel to operate; the power unit is connected with the driving unit, and applies forces in two different directions to the driving unit, so that the driving unit has multiple different operation modes; and therefore,the infusion device has multiple different unit infusion amounts or infusion rates. The driving unit has multiple operation modes; therefore, multi-gear pushing of the driving wheel is achieved; theinfusion device has multiple infusion modes; and thus, the infusion efficiency is greatly improved.

Description

technical field [0001] The invention mainly relates to the field of medical devices, in particular to a drug infusion device with bilateral drive and multiple infusion modes. Background technique [0002] A drug infusion device is a medical device that continuously injects drugs into the patient's body to achieve the treatment of the patient's disease. 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] When performing drug infusion, currently existing infusion devices can only pe...

AI Technical Summary

Problems solved by technology

[0003] When performing drug infusion, the existing infusion devices can only be infused at one gear, the infusion process cannot be flexibly controlled, and the infusion efficiency is relatively low

And the minimum dose that can be infused each time is relatively large, which causes the patient's body fluid level to fluctuate greatly under the control of infusion drugs, and cannot achieve the purpose of more precise control of body fluid level
