Infusion drop monitoring system on basis of sound wave vibration signal

Abstract

The invention discloses an infusion drop monitoring system on the basis of a sound wave vibration signal, which comprises a terminal controller, a ZigBee router, a ZigBee coordinator and a PC (Personal Computer) upper computer. The terminal controller comprises a sound wave signal acquisition device (8), a control main board (7) and a precision stepping clamping motor (9); a diaphragm (3) is arranged on the close contact surface of the sound wave signal acquisition device (8) and a Murphy dropper (2); a diaphragm cavity (4) and a cavity duct (5) are arranged in the sound wave signal acquisition device (8); a pick-up device (6) is arranged at one end of the cavity duct (5); the pick-up device (6) is connected with the control main board (7); and the control main board (7) is connected with the precision stepping clamping motor (9) by a wire. The infusion drop monitoring system has simple and practical structure and low using cost; the infusion speed and the infusion volume are controlled by processing the drop sound wave vibrating signal; and the infusion drop monitoring system has no any radiation influence on liquid medicine.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an infusion drip monitoring system for controlling the infusion speed based on the infusion sound wave vibration signal. Background technique [0002] At present, when medical institutions such as large, medium and small hospitals and subordinate community health centers and clinics in my country perform infusion therapy, the infusion speed and infusion volume are almost all inaccurate. The infusion speed is controlled by the nurse by turning the manual pulley on the infusion set, and the infusion volume is also estimated by the nurse after pouring out the liquid bottle with only two marks. Instruments and equipment such as infusion speed monitoring have not been widely used, which will not only affect the expected therapeutic effect, but also for some drugs that are sensitive to human organs and require strict control of infusion speed and infusion volume, due to ind...

AI Technical Summary

Problems solved by technology

Instruments and equipment such as infusion speed monitoring have not been widely used, which will not only affect the expected therapeutic effect, but also for some drugs that are sensitive to human organs and require strict control of infusion speed and infusion volume, due to individual differences, the tolerance of the body is different, especially in Strictly control the infusion speed and infusion volume during surgery, after major surgery, and in critical condition, which will lead to aggravation of the condition, and some may even be life-threatening

The infusion pump is an effective method to solve the infusion speed. The infusion volume is constant within a certain period of time by using power squeeze infusion, but the infusion speed is not uniform during the period; and the cost of the machine and consumables is too high, so it is only suitable for first aid and medical treatment. severe condition

SJK digital infusion monitoring instrument has stable performance, easy to use and easy to operate, but the price is relatively expensive and there are few applications

Moreover, at present, the drip speed detection of common infusion tubes mainly includes ultrasonic detection, infrared detection, and capacitance detection. Whether such detection will affect the liquid medicine is still under study.
