Automatic dosing device of medical intravenous infusion apparatus

Abstract

The invention relates to an automatic dosing device of a medical intravenous infusion apparatus. A new dosing controller is designed, the dosing controller can automatically control the dosing processaccording to different drugs, only an air pump is used for directly operating the liquid in the control process, and the accuracy is higher than that of an existing dosing device for controlling theinjector type; a medicine storage bottle can be recycled and can be directly stored when not used, and the defect that multiple small-package medicine bottles are inconvenient to store is overcome; acode scanner is used for scanning the medicine bottle, so that a computer can automatically identify medicine in the medicine bottle, in addition, due to the special design, the code scanner can failin scanning when the medicine is insufficient, and therefore the safety and effectiveness of the instrument are guaranteed. A liquid receiving sheet is arranged in the dosing dropper, so that the inflow of the medicine is more accurate. The medicine flow is calculated according to the viscosity of the medicine, and the accuracy of the medicine adding process is guaranteed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an automatic medicine adding device of a medical intravenous infusion set. Background technique [0002] Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the vein using the principles of atmospheric pressure and hydrostatic pressure. Injecting large amounts of fluids, electrolytes, or blood into a vein is called intravenous infusion. Due to the different injection sites and infusions, it can be divided into peripheral venous infusion, central venous infusion, high nutrition infusion (TPN) and blood transfusion. Intravenous infusion therapy is a highly specialized technology, and its treatment level covers parenteral infusion, nutritional support, medication and infusion therapy.

Problems solved by technology

[0003] Application number: 201410166436.8 discloses a pressure extension tube with a dosing device, which mainly includes a screw joint, a dosing pot, a support plate and a recessed joint. The screw joint is used to directly connect the intravenous indwelling needle to ensure sterility; automatic dosing

[0004] Application number: 201510810858.9 discloses an infusion pump. The infusion pump includes a casing, a door body, a fixing seat, a locking plate, a motor and a main control board; although it can automatically add medicine, its structure is complicated and its use is single. Drugs cannot be reused, after one dose, the bottle cannot be recycled

In addition, the precision of its liquid control is not high enough.
