Infusion device based on giant magnetostrictive film

Abstract

The invention discloses an infusion device based on a giant magnetostrictive film. The infusion device comprises a shell, an infusion tube, a first substrate, a second substrate, a first giant magnetostrictive film, a second giant magnetostrictive film and a magnetic field generation assembly, wherein the infusion tube is arranged in the shell in a penetrating manner; the first substrate is arranged on the shell and located on one side of the infusion tube in the radial direction; the second substrate is arranged on the shell and located on the other side of the infusion tube in the radial direction; the first giant magnetostrictive film is arranged on the first substrate; the second giant magnetostrictive film is arranged on the second substrate; the magnetic field generation assembly isarranged on the shell and used for generating a magnetic field, and the magnetic field intensity is adjustable, wherein the first giant magnetostrictive film and the second giant magnetostrictive filmextend or retract under the action of a magnetic field so as to drive the first substrate and the second substrate to bend towards the infusion tube respectively to extrude the infusion tube; and theinfusion tube is continuously extruded by the first substrate and the second substrate by adjusting the magnetic field intensity so as to realize infusion. The infusion speed of the infusion device is stable and uniform, and it can be guaranteed that medicine stably and accurately enters the human body.

Description

technical field [0001] The invention belongs to the technical field of infusion devices, in particular to an infusion device based on a giant magnetostrictive film. Background technique [0002] In normal medical care, it is very common to inject patients with drugs. Infusion is one of the important means of treatment in clinical medicine. It refers to the large-dose injection that is infused into the body by intravenous infusion. It is usually packaged in glass or plastic infusion bottles or bags, and does not contain bacteriostatic agents. When in use, the drip rate is adjusted through the infusion device to continuously and stably infuse the drug into the body. [0003] The infusion pump is an instrument that can accurately control the number of infusion drops or the infusion flow rate to ensure that the drug can enter the patient's body at a uniform speed, accurately and safely. It is also an intelligent infusion device. Affected by the back pressure of the human body ...

AI Technical Summary

Problems solved by technology

However, in the actual use process, there are problems such as wear and aging. In addition, it is often affected by the temperature, humidity, and strong light of the external environment. The resulting medical accidents often occur

[0004] Most of the existing infusion devices still stay in the traditional way, lack of intelligence and informatization, the infusion speed cannot be accurately controlled, and the infusion speed is easily disturbed by the patient's activities, resulting in the patient's infusion not receiving perfect care

Existing infusion pumps have a series of potential safety hazards such as out-of-control medicine
