an infusion device

Abstract

The invention discloses an infusion device, which comprises an infusion bag and an infusion hose. One end of the infusion hose is connected with the infusion bag, and the other end is connected with a flow rate controller. The output end of the flow rate controller is connected with a Luer connector. The tube is provided with a drug injection port, a first switch clip and an exhaust filter in sequence, and the flow rate controller includes a quartz glass cylinder, which is connected with a Luer connector through a restrictor tube, and a capillary tube is arranged inside the quartz glass cylinder. , the capillary is connected with the current limiting tube, the outer wall of the quartz glass cylinder is covered with a phase change heat storage layer, the outer wall of the phase change heat storage layer is covered with a heat conduction layer, and the heat conduction layer is connected with a heating element, the phase change heat storage The interior of the layer is filled with a phase change energy storage material. The invention can effectively control the infusion speed and infusion stability, and can maintain a certain temperature when the medicinal liquid enters the human body, which is beneficial to improving the patient's comfort during infusion.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an infusion device. Background technique [0002] The infusion device is a device used to inject medicinal liquid into the human body through an infusion hose. Generally, the pressure generated by the height difference between the liquid and the human body is used to inject the medicinal liquid into the human body to achieve the purpose of treatment. However, the infusion speed of the existing infusion device is not easy to control, and the infusion is unstable or the infusion speed is too fast to make the patient feel uncomfortable, and it is not conducive to the full absorption of the medicinal liquid; The temperature of the liquid medicine is relatively low, and when it enters the human body, it will cause a drop in body temperature and constriction of the blood vessels, thereby exacerbating the discomfort of the patient. However, the existing infusion devices cannot...
