Electrical impedance signal collecting device

Abstract

The invention relates to a medical device, in particular to an electrical impedance signal collecting device. An electrical impedance tomography signal collecting device comprises an elastic band, an outer layer bandage, a traction belt and a plurality of signal collecting units. The traction belt is provided with a traction belt magic tape hook surface, the signal collecting units are evenly distributed on the elastic band, the traction belt penetrates the outer layer bandage to be connected with the elastic band, an electrode protruded part is connected with the magic tape hook surface, a bowl part penetrates a through hole to contact with the human head, and the part of the electrode bowl part contacting the head can be coated with conductive paste. The outer layer bandage comprises an outer layer bandage head and an outer layer bandage tail. The inner side of the outer layer bandage head is provided with an outer layer bandage magic tape hook surface, and the outer side of the outer layer bandage is provided with an outer layer bandage hair surface. The elastic band meets the adaptation to the size of a target, the small bandage meets a requirement of comfort, and a lint layer design conforms to the ergonomics design.

Description

technical field [0001] The invention relates to medical equipment, in particular to an electrical impedance signal acquisition device. Background technique [0002] Electrical impedance tomography is a new direction of medical imaging technology. Its basic principle is that different tissues in the human body have different resistance / conductivity under different physiological and pathological conditions, and various methods are used to apply small safety drives to the human body. Current or induced current, by measuring the response information of the driving current in the human body, the image of the resistivity distribution or its change inside the human body is reconstructed. Electrical impedance tomography has many advantages, such as non-invasive to the human body, no risk of ionization and radiation, simple system structure, easy measurement, can be used for fast portable imaging, and continuous dynamic image monitoring of the human brain, stomach and lungs It has a...

Problems solved by technology

The bottleneck in the application of electrical impedance imaging technology lies in the layout of the acquisition radio or electrodes. At present, there is no layout method suitable for clinical use. The acquisition of electrical impedance imaging signals needs to meet the following conditions: the antenna or electrodes are evenly arranged around the target; The size of the target perimeter has certain adaptability; certain fastness; each antenna or electrode must be able to be independently viewed to meet the needs of installation and maintenance
