Problems solved by technology

[0004] However, in the current infusion devices, the infusion speed of the hanging bottle type infusion device is related to the position of the infusion bottle or the infusion bag, and the infusion speed is mostly set manually by the visual inspection and experience of the medical staff; the infusion speed of the peristaltic infusion device It is highly affected by the extrusion force of peristalsis and the deformation of the infusion tube, and it is difficult to effectively control and predict the extrusion force and deformation of the infusion tube. Therefore, it is necessary to replace the infusion tube frequently, and the cost is high. Bottles are still needed, which has high requirements for infusion occasions and is inconvenient to use
Moreover, neither the existing bottle-type infusion device nor the peristaltic infusion device can guarantee the accuracy and stability of the infusion speed, which affects the infusion accuracy and easily causes medical accidents

Abstract

The invention discloses an infusion device and an infusion control method. The infusion device comprises an air pump, a balance cabin, a gas transmission tube, an infusion tube, a light curtain detection assembly and a first controller; the air pump is connected with the balance cabin; the balance cabin is connected with a liquid container through the gas transmission tube; a drip pot is arranged inside the infusion tube; liquid flowing into the infusion tube from the liquid container forms into liquid drops in the drip pot; the light curtain detection assembly is used for detecting the liquid drops in the drip pot through a generated detection light curtain and sending a first detection signal to the first controller when detects the liquid drops; the first controller is used for calculating first dripping speed of the liquid drops in the drip pot according to the first detection signal, comparing the first dripping speed with preset dripping speed and controlling the air pump to pump gas to the balance cabin to control the balance cabin to discharge the gas to adjust an air pressure value inside the balance cabin to enable the first dripping speed to be matched with the preset dripping speed. Accordingly, infusion stability and accuracy can be guaranteed and medical negligence can be reduced.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to an infusion device and an infusion control method. Background technique [0002] Infusion therapy is one of the most commonly used clinical treatment methods, which refers to the infusion of medicinal liquid into the venous blood vessels of the body through intravenous infusion. The medicinal liquid used in infusion therapy is usually packaged in glass or plastic infusion bottles or bags. During treatment, the infusion speed is adjusted through the infusion device, and the medicinal liquid is continuously and stably injected into the human vein to provide the human body with medicinal liquid, body fluid, and electrolytes. or provide nutrients. Because the dosage of infusion therapy is large, and the medicinal liquid is directly injected into the veins of the human body, when infusion therapy is used, the requirements for the accuracy and stability of the infusi...
