Embodiment 1

[0038] The present embodiment provides a method for adjusting the dripping speed of an infusion pump, including:

[0039] Compare the set dripping speed with the preset dripping speed threshold, and select the dripping speed adjustment mode according to the comparison result. The preset dripping speed threshold value ranges from 10 to 45 drops / min. In the following embodiments, the preset dripping speed is used. The threshold value is 15 drops / min as an example to illustrate.

[0040] If the set drip rate does not exceed 15 drops / min, use the start / stop adjustment mode, such as figure 1 As shown, the process includes:

[0041] A1: Set the interval time between each drop. The interval time t of each drop is calculated by the following formula: t=T / V 设 , where V 设 Indicates the set dripping speed, and T represents the unit time corresponding to the dripping speed. Taking the unit of dripping speed as drips / min as an example, T is 1 minute.

[0042] A2: When the motor is run...

Embodiment 2

[0054] This embodiment provides an infusion pump dripping speed adjustment system, including a control module, a dripping speed sensor connected to the control module, and a motor of the infusion pump;

[0055] The dripping speed sensor is used to detect the dripping speed and transmit it to the control module;

[0056] The control module is used to control the motor of the infusion pump by executing the method for adjusting the dripping speed of the infusion pump described in Embodiment 1.

[0057] During implementation, the dripping speed sensor is an infrared opposite-beam dripping speed sensor.

Abstract

The invention discloses an infusion pump dripping speed adjusting method and system.The infusion pump dripping speed adjusting method comprises the steps that if the set dripping speed does not exceed a preset dripping speed threshold value, a starting / stopping adjusting mode is adopted, and the starting / stopping adjusting mode comprises the steps that the interval duration of each dripping is set; the motor runs, and when it is detected that one drop of liquid drops drops, the motor is stopped; detecting whether the interval duration of each drop is reached or not, if so, restarting the motor, and repeating the process; if the set dripping speed exceeds the preset dripping speed threshold value, a speed compensation adjusting mode is adopted, and the speed compensation adjusting mode comprises the steps that an adjusting period is set; if it is detected that the dripping speed is larger than the set dripping speed at the end of one period, a speed compensation coefficient is calculated according to the time difference exceeded by the current period, and the frequency of the motor is reduced according to the speed compensation coefficient; if it is detected that the dripping speed is smaller than the set dripping speed at the end of one period, a new speed compensation coefficient is calculated according to the current speed compensation coefficient multiplied by a preset coefficient, and the frequency of the motor is increased according to the new speed compensation coefficient. And over-excitation-free adjustment of the speed is realized.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a method and system for adjusting the dripping rate of an infusion pump. Background technique [0002] With the development of embedded in the medical industry, more sensor technologies are applied in the medical industry, making various medical devices more intelligent, safe and efficient. As an important member of medical devices, infusion pumps have also been given more missions. [0003] In the prior art, the infusion pump is often equipped with a drip rate sensor module for detecting the number of drips, and forms a closed-loop control with the infusion pump according to the drip rate. [0004] Due to different structural differences in the infusion pump, different closed-loop control systems will have different degrees of over-regulation. Once the over-regulation occurs, it will increase the risk of using the infusion pump. [0005] Over-excited adjustment means...
