Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0023] Such as figure 1 As shown, the specific embodiment of the present invention is to provide a liquid infusion method based on piezoelectric precise control, comprising the following steps:

[0024] Input Parameters: Enter the infusion parameters, including the total amount of fluid infused and the flow rate.

[0025] The specific implementation process is: inputting infusion parameters through the input module 10, including inputting the total amount of infusion liquid and the flow rate of the infusion liquid.

[0026] Obtain control parameters: determine the infusion time according to the infusion parameters, according to Q=(V 0 +ΔV)f·60 determines the vibration frequency of the piezoelectric vibrator, where: Q represents the input flow per minute, V 0 represents the volume of the cavity, ΔV represents the variation of the volume of the c...

Abstract

The invention relates to a liquid infusion method and system based on piezoelectric precise control. The method comprises the steps that parameters are input, wherein the infusion parameters are input, and the infusion parameters comprise the infusion liquid total weight and flow speed; control parameters are obtained, wherein infusion time and the vibration frequency of a piezoelectric vibrator are obtained according to the formula that Q is equal to (V0+delta V)f.60 and the infusion parameters; the piezoelectric vibrator is driven, wherein driving voltage is applied to the piezoelectric vibrator at the determined infusion time, and the driving voltage drives the piezoelectric vibrator to work at the determined vibration frequency; liquid infusion is carried out, wherein vibration of the piezoelectric vibrator controls a cavity to be expanded and compressed, and therefore liquid input and output are completed. Expansion and compression of the cavity are controlled through vibration of the piezoelectric vibrator, therefore, liquid input and output are completed, intelligent control is conveniently carried out, infusion precision is ensured, and precise infusion control of liquid is achieved.

Description

technical field [0001] The invention relates to a liquid infusion method and system, in particular to a piezoelectric-based liquid infusion method and system capable of precise control. Background technique [0002] Infusion pumps have been widely used in clinical treatment, and have been widely used in anesthesia, analgesia, antibiotic treatment, tumor chemotherapy, cardiovascular and cerebrovascular disease treatment, hypertension, and diabetes treatment in China. The application of the infusion pump reduces the treatment risk of the treated patients, reduces the workload of the nursing staff, and greatly reduces the risk of administration of traditional infusion methods during the treatment of seriously ill patients. [0003] The quality and safety of medical devices is the top priority of hospital management, so it is hoped to have a high-performance, intelligent automatic infusion device. The intelligent infusion pump has the incomparable advantages of traditional grav...
