Electrode band, electrode structure, feed line and electrical impedance imaging equipment

Abstract

The invention provides an electrode band, an electrode structure, a feed line and an electrical impedance imaging device. The electrode band comprises: a band (1) which is elastic and is provided witha first surface (11) and a second surface (12) which are opposite to each other; and a plurality of electrodes (4) fixed on the first surface (11) and provided with male buckles (43) which penetratethrough the belt (1) and are exposed on the second surface (12), wherein the male buckles (43) are electrically connected with the electrodes (4). The electrode band is simple in structure and low incost, and can rapidly and conveniently fix the electrodes to the body of an object to be measured, and the fixing efficiency is high; when the electrode band elastic, so when the electrode band is fixed on the periphery of the thoracic cavity of the measured object, the elastic force of the band is converted into pressing force on the electrodes, so that good contact between the electrodes and theskin of the thoracic cavity can be ensured; and the electrode band and the feed line are arranged in a split mode through the male buckle and the female buckle, so the design of the electrode band issimplified, the feed line can be repeatedly used, and the replacement cost of the electrode band is reduced.

Description

technical field [0001] The invention belongs to the technical field of biomedical electrical impedance imaging, and more specifically relates to an electrode belt, an electrode structure, a feeding line and electrical impedance imaging equipment. Background technique [0002] Electrical impedance tomography (Electrical Impedance Tomography, EIT) is a technology that utilizes the electrical impedance characteristics of the measured organism organs and tissues for imaging. The electrical impedance characteristics of various tissues and organs in the living body (such as the thoracic cavity) are significantly different, and the image reconstructed by the electrical impedance imaging technology has a high contrast. Due to the advantages of high resolution, low cost, portable equipment, no radiation and non-invasiveness, electrical impedance imaging has broad application prospects. [0003] In order to perform biomedical electrical impedance imaging, a certain number of electrod...

Problems solved by technology

[0004] At present, there are two ways to fix the electrodes on the body of the subject to be measured. One is to manually fix 16 electrodes around the body of the subject to be measured one by one. In this fixing method, the electrode paste process is cumbersome and the electrodes cannot be guaranteed. Uniform distribution and complicated electrode feeding lines; the other is to fix 16 electrodes on the belt first with the help of a belt, and then fix the belt around the body of the object to be measured. This fixing method has the following disadvantages: the belt has poor elasticity, It is difficult to maintain good contact between the electrode and the biological tissue all the time, the electrode feeding line is complicated, the operation is inconvenient, the length of the belt needs to be adjusted according to the size of the object to be measured, and the cost is high, etc.
