Problems solved by technology

However, the existing analog detection device is only to meet the simulation of lung movement in breathing, which is too simple and rough, and the accuracy is poor, so it cannot be applied to EIT electrical impedance imaging test
[0004] Therefore, the poor accuracy of detection caused by simple and rough analog detection devices is an urgent problem to be solved

Embodiment Construction

[0028] In describing the present invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", The orientation or positional relationship indicated by "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than Nothing indicating or implying that a referenced device or element must have a particular orientation, be constructed, and operate in a particular orientation should therefore not be construed as limiting the invention.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or ...

Abstract

The invention provides a respiratory system simulation test device for chest EIT. The respiratory system simulation test device for chest EIT comprises a breathing assembly, an upper limb model and conductive liquid; the upper limb model is internally provided with a cavity, and the breathing assembly can be fixedly accommodated in the cavity; the conductive liquid is filled in the cavity and located on the outer side of the breathing assembly; and the breathing assembly comprises a left lung lobe model, a right lung lobe model and a trachea, and the trachea exhales and inhales through external equipment to enable the left lung lobe model and the right lung lobe model to expand or contract so as to act on the conductive liquid in the cavity, so that the height of the conductive liquid is changed. According to the respiratory system simulation test device for chest EIT provided by the technical scheme of the invention, the detection accuracy of the respiratory system simulation test device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a respiratory system simulation test device for chest EIT. Background technique [0002] Electrical impedance imaging (Electrical Impedance Tomography, EIT) is a non-invasive technology that aims at the electrical resistivity distribution inside the human body to reconstruct tissue images in the body. The human body is a large bioelectrical conductor, and each tissue and organ has a certain impedance. When a local organ of the human body becomes diseased, the impedance of the local part must be different from that of other parts. Make a diagnosis. [0003] The EIT simulation detection can be carried out through the simulation imaging detection device first, so that the simulation analysis result can be obtained in a very short time. The simulation detection device in the prior art generally consists of three parts: a simple nylon hollow tube, a retractable silicone airb...
