Bioelectric impedance measurement auxiliary device and bioelectric impedance measurement system with bioelectric impedance measurement auxiliary device

Abstract

The invention discloses a bioelectric impedance measurement auxiliary device. The device comprises two conductive brackets, the conductive brackets are provided with electrode connection parts and touch parts which are electrically connected, the electrode connection parts provide preset conductive area, and the touch parts contact the finger skin of the preset area. When bioelectric impedance ismeasured, the conductive brackets are arranged on wearable equipment, it is ensured that a first bioelectric impedance measurement electrode is conducted through contact, then the fingers are placed on the touch parts, and the contact area between the conductive brackets and the fingers and the contact area between the conductive brackets and the first bioelectric impedance measurement electrode remain unchanged. The bioelectric impedance measurement auxiliary device solves the problem that the contact area between the fingers and the electrode is changed during bioelectric impedance measurement, ensures that the contact area is unchanged, reduces the error, and improves the measurement accuracy rate. The invention further discloses a bioelectric impedance measurement system with the aboveauxiliary device.

Description

technical field [0001] The invention relates to the field of biological parameter measurement, in particular to an auxiliary device for measuring biological impedance. In addition, the invention also relates to a biological impedance measurement system with the auxiliary device. Background technique [0002] Body fat measurement is to obtain the health status information of the human body by measuring the fat content in the human body. In the prior art, the bio-impedance of the human body can be measured through a bio-impedance measurement system to obtain body fat, such as body fat measurement watches, body fat A body fat measurement wearable device such as a wristband is provided with a first bio-impedance measurement electrode on the front, and a second bio-impedance measurement electrode with the back. When measuring body fat, the second bio-impedance measurement electrode is in contact with the skin of the wrist wearing the wearable device, and the other hand stretches...

AI Technical Summary

Problems solved by technology

[0003] However, the existing first bio-impedance measuring electrode has an arc-shaped structure. In the process of measuring body fat, the influence of the external environment and the change of finger pressure will lead to changes in the contact area between the finger and the electrode, which in turn will lead to a change in the measured value of body fat. If the variables cannot be controlled during multiple measurements, effective measurement data cannot be formed, and the measurement results have large errors, and the inconsistency of the finger sizes of different users will also lead to inaccurate measurement data, which cannot form effective comparison data.
