Problems solved by technology

[0002] At present, the medical use of electrical tomography is being gradually promoted, and relevant measuring instruments for lung imaging have appeared. However, the current lung imaging quality is low, and the imaging accuracy is limited, which is of limited help to actual medical research. Considering normal lung imaging In the electrical tomography of the lungs, the change of the lung conductivity caused by inhalation of air during the detection of lung respiration is not large, which is the main reason for the low imaging quality.

Embodiment Construction

[0008] The measuring method of the present invention utilizes the original measuring instrument and adopts a common adjacent electrode excitation method, and additionally installs measuring and exciting electrodes on the periphery of the lung.

[0009] Before measuring the data, use such as figure 1 The inhalation device shown inhales the contents of the bottle into the lungs.

[0010] Such as figure 1 As mentioned above, the inhalation device adopted in the present invention is composed of a suction head 6 and a main body bottle. There are 5 rubber interfaces in the main body bottle, which are tightly connected with the suction head 6 to prevent air leakage of the device. 4 is a switch valve, the material in the valve main body bottle can be charged in the suction head 6 through the valve. 3 is a substance inlet port, through which the inhaled substance is added into the main body bottle, and 2 is a substance storage place, which is used to atomize or mix the added substanc...

Abstract

The invention relates to a measuring method for lung electrical tomography. The method comprises the steps that materials to be sucked into the lung are contained in a container, one of a heating device or dispersion devices including an ultrasonic device are selected according to different materials to be sucked into the lung, the materials to be sucked into the lung are mixed with oxygen or air and dispersed into the container, and when the lung electrical tomography is performed, a person to be tested sucks the materials dispersed into the container into the lung through the respiratory organ; the materials to be sucked into the lung can change the specific conductance of lung pulmonary alveoli in the respiratory process.

Description

technical field [0001] The invention belongs to the field of design and measurement of electric resistance tomography data acquisition system. Background technique [0002] At present, the medical use of electrical tomography is being gradually promoted, and relevant measuring instruments for lung imaging have appeared. However, the current lung imaging quality is low, and the imaging accuracy is limited, which is of limited help to actual medical research. Considering normal lung imaging In electrical tomography of the lungs, the electrical conductivity of the lungs caused by inhalation of air does not change much during the detection of lung respiration, which is the main reason for the low imaging quality. Contents of the invention [0003] The purpose of the present invention is to provide a measurement method of lung electrical tomography that can optimize the results of lung imaging without changing the existing measuring instruments. The invention changes the condu...
