Embodiment Construction

[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] It should be noted that bioelectrical impedance imaging belongs to functional imaging. According to the physical principle that different tissues in the organism have different electrical impedances, the electrical impedance inside the human body can be reconstructed by injecting a small safe current into the organism and measuring the potential of the body surface. distribution image. Bioelectrical impedance imaging extracts the electrical characteristic information of tissues or organs related to the physiological and pathological state of the organism through the electrode array arranged on the body surface of the organism, which not only reflects the anatomical structure, but also gives functional image results. Therefo...

Abstract

The invention discloses a biological electric impedance measuring electrode, which is characterized in that the electrode comprises a viscous stratum basale, an electrically conductive adhesive layer, a connecting fastener and a laying, wherein the electrically conductive adhesive layer, the viscous stratum basale and the laying are connected in turn, the connecting fastener is off-center designed, the electrically conductive adhesive layer has a cylindrical shape, and the connecting fastener is electrically connected with the electrically conductive adhesive layer. The invention can ensure the tight contact of the electrode and measured body surface, avoids the conditions that the electrode moves or looses or falls off the measured body, thereby effectively improving the precision and repeatability of the measurement value when the biological electric impedance is measured, additionally, the invention can receive consistent electrical characteristics when measuring the biological electric impedance, decrease the possibility of generating error, and ensure the consistency of contact electrical impedance which is measured in each time. Further more, the invention can further avoid the inference to the biological electrical impedance which is caused by the movement of the measured body, and guarantees the precision of the measured value.

Description

technical field [0001] The invention relates to the field of electrical measurement, in particular to an electrode for bioelectrical impedance measurement in the field of bioelectrical impedance measurement and a method for using the electrode for measurement. Background technique [0002] Bioelectrical impedance, or impedance measurement technology for short, is a detection technology that uses the electrical characteristics of biological tissues and organs and their changing laws to extract biomedical information related to human physiological and pathological conditions. The use of bioelectrical impedance methods can achieve non-invasive, Highly sensitive and accurate extraction of corresponding electrical characteristics and their change information. It can be used to measure and monitor various electrical parameters of organisms, such as electrocardiography, bioimpedance measurement, electroencephalography, etc., including placing electrodes on the organism, and then me...
