Wearable limb circumference measuring device

Abstract

The invention discloses a wearable limb circumference measuring device and relates to the technical field of measuring devices. The wearable limb circumference measuring device solves the problem of incapability of online and in real time measuring circumference during a long period of time. The wearable limb circumference measuring device is technically characterized by comprising a circumferencesensor, a driver and a data collecting processor, wherein the driver comprises a sensor interface, an information issuing interface and an original data processing module; the data collecting processor comprises an information collecting exchange interface and a data processing and visualizing module; the driver is communicated with the data collecting processor; the circumference sensor comprises a retractable sensing unit and an elastic base, and the retractable sensing unit is fixedly mounted on the elastic base and is composed of a light emitting module, a light receiving module and a flexible light guide element. The luminous flux can be in one-to-one correspondence with the circumference of an object to be measured, so that the wearable limb circumference measuring device can determine the circumference of the object to be measured according to output current and achieve a function of automatically, in real time and online monitoring the circumference of the object during a longperiod of time.

Description

technical field [0001] The invention relates to the technical field of measuring devices, in particular to a wearable limb circumference measuring device. Background technique [0002] The wearable limb circumference measuring device is a measuring device used to measure the circumference of an object. The wearable limb circumference measuring device is not limited to the measurement of the circumference of human and animal limbs, and can also be applied to the circumference of other cylindrical objects. field of measurement (such as the diameter of a tree trunk, etc.). [0003] At present, measuring the circumference of a cylindrical object can only be done manually with a ruler, and there is no suitable telescopic sensitive component in the field of circumference measurement. The Chinese utility model patent with the announcement number CN203724095U disclosed a circumference measuring device on July 23, 2013, and the Chinese utility model patent with the announcement numb...

AI Technical Summary

Problems solved by technology

Many application scenarios require real-time online monitoring of circumference changes over a long period of time. In these scenarios, repeated manual measurement of the circumference cannot be performed, such as monitoring the muscle expansion of athletes during exercise, etc.

However, none of the above-mentioned existing solutions can be worn for a long period of time, and manual measurement must be performed every time the measurement is made, and real-time online monitoring of the measured object cannot be carried out for a long period of time, which limits the usage scenarios

Therefore, there is a problem in the existing technology that the circumference cannot be monitored online in real time for a long period of time
