Infusion device

Abstract

The invention discloses an infusion device. The infusion device comprises an infusion bag and an infusion hose; one end of the infusion hose is connected with the infusion bag, and the other end of the infusion hose is connected with a flow speed controller; the output end of the flow speed controller is connected with a Luer taper; a medicine injection port, a first switch clamp and an exhaust filter are sequentially arranged on the infusion hose; the flow speed controller comprises a quartz glass cylinder; the quartz glass cylinder is connected with the Luer taper through a flow limiting tube; a capillary tube is arranged in the quartz glass cylinder and communicates with the flow limiting tube; the outer wall of the quartz glass cylinder is coated with a phase change heat storage layer;the outer wall of the phase change heat storage layer is coated with the heat conduction layer; the heat conduction layer is connected with the heating element; and the phase change heat storage layer is filled with a phase change energy storage material. The infusion speed and infusion stability can be effectively controlled, a certain temperature can be maintained when liquid medicine enters ahuman body, and the comfort degree of a patient during infusion can be improved.

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...
