Flexible liquid flow monitoring device

Abstract

The invention provides a flexible liquid flow monitoring device and belongs to the technical field of fluid measurement. The flexible liquid flow monitoring device comprises a flexible paster, wherein the flexible paster comprises a flexible sensor, a flexible film power supply and a flexible circuit module, the whole flexible paster is in the shape of a flat belt, and a hose can be wrapped in the flexible paster to enable the flexible sensor to be attached to the outer wall of the hose; the flexible film power supply provides power for the flexible sensor and the flexible circuit module. The fact that the wall of the hose expands slightly when fluid flows through the hose is utilized, the tension change of the wall of the hose caused by fluid flowing can be sensed by the high-sensitivity flexible sensor in the flexible paster in which the hose is wrapped, and then tension data sensed by the flexible sensor can be processed by the corresponding flexible circuit module so that the flow condition of fluid in the hose can be obtained indirectly. The flexible liquid flow monitoring device is simple in structure and convenient to use, and a user only needs to wrap the hose in the flexible paster.

Description

technical field [0001] The invention belongs to the technical field of fluid measurement, in particular to a flexible liquid flow monitoring device. Background technique [0002] Flow parameters are necessary parameters in biomedical analysis, industrial production, scientific experiments and various economic calculations, especially the measurement and control of liquid flow is particularly important in the fields of medicine, pharmacy, analytical instruments and molecular biology. For example, in biomedical research, it is often necessary to observe the effects of different blood supply volumes on the functions of blood supply tissues and organs, but for a long time there has been a lack of instruments and equipment that can flexibly measure and control blood vessel blood flow according to actual needs. In addition, the measurement of blood flow has practical value for checking cardiovascular function and diagnosing vascular diseases. Another example is a diabetic patient...

Another example is a diabetic patient who hopes to monitor the amount of insulin injected continuously for 24 hours and adjust the flow of insulin in time according to the changes in blood sugar in the patient’s body, but there is no way to do so at present

[0003] In recent years, with the rapid development of the fine chemical industry and biomedical analysis, the requirements for measurement and control in the field of micro-flow liquid transported by small hoses have become higher and higher, and traditional flow measurement devices have been difficult to meet the requirements.
