Liquid dropping speed monitoring device

Abstract

The invention discloses a liquid dropping speed monitoring device which comprises a display module, an alarm module, an infrared water level judgment module, a single-chip microcomputer, a keyboard controller, an infrared speed measurement module, a motor driver and a stepping motor, wherein the single-chip microcomputer is connected with the display module, the alarm module, the infrared water level judgment module, the keyboard controller, the infrared speed measurement module and the motor driver respectively; the motor driver is connected with the stepping motor; the stepping motor is connected with the infrared speed measurement module; the speed of water dropping is controlled by using the stepping motor and the principle of the pressure intensity; and according to the formula P=Rho * g * h, as the heights of liquid levels are different, pressure intensities are different, and the liquid dropping speed is changed. According to the liquid dropping speed monitoring device, a keyboard can be prepared for controlling the speed, and an alarm can be given; and equipment is simple in structure, low in cost and favorable for wide popularization and use.

Description

technical field [0001] The invention relates to a monitoring device for liquid dripping speed. Background technique [0002] At present, the intravenous infusion sets used in the market are all suspended above the patient to infuse, and the infusion speed is difficult to accurately limit, which will cause inconvenience to intensive care patients and patients who have stricter infusion speed, while the existing infusion clinical control Alarms are large in size, heavy and relatively expensive, increasing the costs of hospitals and patients. Contents of the invention [0003] The object of the present invention is to provide a monitoring device for dripping speed of liquid, so as to solve the above-mentioned multiple defects caused by the prior art. [0004] The present invention adopts following technical scheme: [0005] In order to achieve the above object, the present invention provides a liquid drip speed monitoring device, comprising a display module, an alarm module...
