Problems solved by technology

[0004] Although the infrared sensing method can be used to measure the dripping speed under certain circumstances, the above-mentioned device needs to place an infrared emitting tube and an infrared receiving tube close to both sides of the dripping pot, and adjust the emitting tube, dripping liquid, and receiving tube to be at the same position. Accurate measurement can only be done on a straight line. There are problems that the measurement is inaccurate after the drip pot is tilted, it cannot be adapted to all drip pots, the installation and adjustment requirements are high, the volume is large, and it is not practical.

Abstract

The invention provides an infusion tube dripping speed measuring device which is provided with an antenna and a processor. Incident microwaves are transmitted to liquid drops in a drip cup through theantenna, the reflected waves from the liquid drops are received, the processor utilizes the Doppler effect to judge liquid drop falling according to the incident microwaves and the reflected waves, the number of the liquid drops in an infusion tube in unit time is measured by adopting the method, and more accurate liquid drop measurement results can be obtained. In addition, the infusion tube dripping speed measuring device is installed on the infusion tube, can be installed at the upper portion or lower portion of the drip cup, has the low requirement for inclination and installing adjustment requirements on the drip cup, adapts to various drip cups and has the advantages of being safe in use, accurate in measurement and small and exquisite in structure.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a device for measuring the drop rate of an infusion tube and a control device for the infusion tube. Background technique [0002] At present, there are many types of Murphy's droppers used for medical drip infusion, and the styles and sizes of dripping pots are different. [0003] At present, the known method for measuring the drip rate of medical drip infusion is to use infrared sensing technology, install infrared emitting tubes and infrared receiving tubes on both sides of the drip pot, and measure the drip rate by blocking the infrared signal when the drip falls. [0004] Although the infrared sensing method can be used to measure the dripping speed under certain circumstances, the above-mentioned device needs to place an infrared emitting tube and an infrared receiving tube close to both sides of the dripping pot, and adjust the emitting tube, dripping liquid, a...
