[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. Liquid medicine flowing into an infusion tube is conveyed by a peristaltic pump when the peristaltic pump is started; air is pumped into a balancing bin when an air pump is started; the balancing bin is used for delivering the air into a liquid medicine container to provide air pressure so as to enable the liquid medicine to flow into the infusion tube from the liquid medicine container; the liquid medicine flowing into the infusion tube form the liquid medicine container forms liquid drops in a drip cup; a light curtain detection assembly is used for detecting the liquid drops in the drip cup and sending a first detection signal to a first controller when detecting the liquid drops; the first controller is used for controlling the working states of the peristaltic pump and the air pump in different stages, and computing the first dripping speed according to the first detection signal and controlling the speed rate of the peristaltic pump for delivering the liquid medicine flowing into the infusion tube or the speed rate of the air pump for pumping the air into the balancing bin according to the comparative result of the first dripping speed and the preset dripping speed, and thus the first dripping speed is made to be matched with the preset dripping speed. In this way, the stable and precise infusion process can be guaranteed, and medical accidents can be reduced effectively.
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...
