Variable speed infusion method and device thereof

Abstract

The invention discloses a variable speed infusion method and a device thereof. The method comprises the following steps: (a), a control unit reads parameters of an infusion phase of an infusion process table; (b), the control unit outputs control signals to a medical pump according to speed parameters of the read infusion phase, the medical pump carries out infusion on a patient, and the control unit starts a timing module to time according to time parameters of the read infusion phase at the same time; (c), when the timing module times to a set value of the time parameters, the control unit reads parameters of a next infusion phase of the infusion process table, and the step b is repeated. The variable speed infusion device comprises the medical pump and the control unit, wherein the control unit comprises the timing module and a memory module storing the infusion process table. The invention is internally provided with the infusion process table, the control unit controls the medical pump to work according to the set parameters of the infusion process table, thereby an infusion process is automatically completed, the workload of medical staff is lowered, the infusion speed is accurately controlled, and complications of the infusion and drug input are reduced or avoided.

Description

technical field [0001] The invention relates to medical infusion equipment, in particular to a variable-speed infusion method and its device. Background technique [0002] Infusion is a frequently used medical behavior with low cost and quick effect, so it is widely used in clinical, hospitalization and emergency treatment. The manually adjusted rolling primary infusion pump relies on the gravity of the liquid to complete the infusion. Although the cost is low, it needs frequent adjustments, and its adjustment accuracy is poor. The Chinese patent document with the publication number CN1743017A discloses "an infusion pump without a pump door structure", which uses a peristaltic pump to provide power to complete the infusion, and has the characteristics of precise infusion speed control. [0003] Due to the reaction of the human body to the drug and the infusion process, the infusion speed needs to be adjusted during the infusion process. For example, injecting ritodrine and...

AI Technical Summary

Problems solved by technology

For example, injecting ritodrine and other tocolytics to pregnant women can prevent miscarriage caused by uterine contraction, but the drug has side effects, and the injection process has a lot to do with the physique of the pregnant woman. so that the human body can gradually adapt to the drug and infusion process

In the existing technology, the adjustment of the infusion speed needs to rely on the sensory experience of the medical staff to manually operate, which not only increases the workload, but also makes the adjustment inaccurate
