Abstract
The present invention relates to a kind of measuring method of lung's electricity tomography, be placed in the material of lung to be sucked in container by the method, the difference of the material according to lung to be sucked, from heater or including selecting one kind in the dispersal device including ultrasonic unit, the material of lung to be sucked is mixed and be scattered in container with oxygen or air, when carrying out lung's electricity tomography, people to be measured is set to pass through the material suction lung that respiratory apparatus will be scattered in container；The material of described lung to be sucked is the material that can change human body electrical conductivity of pulmonary alveoli in respiratory.
Description
Technical field
The invention belongs to resistance chromatography technical data acquisition system design and fields of measurement.
Background technology
At present, the medical science of electricity tomography occurs in that the measurement of correlation for lung's imaging using progressively promoting
Instrument, but current lung's image quality is relatively low, and imaging precision is limited, helps limited for practical medical research, it is contemplated that just
The lung's conductivity variations caused due to suction air in lung respiratory are detected in normal lung's electricity tomography less,
It is the relatively low main cause of image quality.
The content of the invention
It is an object of the invention to provide one kind on the premise of existing measuring instrument is not changed, lung's imaging knot can be optimized
A kind of measuring method of lung's electricity tomography of fruit.The present invention material different from normal air by sucking electrical conductivity,
Change the electrical conductivity of human body pulmonary alveoli in respiratory, so as to improve the imaging results that electricity chromatography is imaged on lung.This
The technical scheme of invention is as follows：
Be placed in the material of lung to be sucked in container by a kind of measuring method of lung's electricity tomography, the method, root
According to the difference of the material of lung to be sucked, from heater or including selecting one kind in the dispersal device including ultrasonic unit,
The material of lung to be sucked is mixed and be scattered in container with oxygen or air, when carrying out lung's electricity tomography, makes to treat
Survey the material suction lung that people will be scattered in container by respiratory apparatus；The material of described lung to be sucked is to change
The material of human body electrical conductivity of pulmonary alveoli in respiratory.
Preferably, the material of described lung to be sucked is carbon dust, iron powder, alcohol or silicone oil.
It is a feature of the present invention that on the basis of the measurement of conventional electrical chromatographic data is not changed, only increasing by suction
The material of different electrical conductivity, improves imaging effect.
Brief description of the drawings
The suction apparatus that Fig. 1 present invention is used.
Specific embodiment
Measuring method of the invention is by original measuring instrument, the method encouraged using common adjacent electrode, in lung
Portion periphery installs measurement and exciting electrode additional.
Before measuring data, using suction apparatus as shown in Figure 1 by vial matter suction lung.
As described in Figure 1, the suction apparatus that the present invention is used is made up of flooded suction 6 and main body bottle, has rubber at 5 in main body bottle
The interface of material, is closely connected with flooded suction 6, anti-locking apparatus gas leakage.4 is controlled valve, opens the material in valve body bottle
Just can be filled with flooded suction 6 by valve.3 is material access port, and inhaled material is added in main body bottle from the mouth, and 2 deposit for material
Place is put, for object atomization or well mixed will to be added, is easy to suction.Heating or ultrasonic unit are provided with 1.
Be inhaled into material can for solid powder, heat, rock or ultrasonic exciting by way of by device
Air and solid powder are well mixed.
Being inhaled into material can also be boiled for liquid by heating, and the mode such as ultrasonic atomization is by liquid substance mist
Change is easy in suction lung.
In order to prevent asphyxia, need to be mixed into appropriate oxygen or air in suction apparatus.
In measurement process, by the device for opening of suction apparatus breaker in middle valve 4, say on nose or mouth alignment suction apparatus
The flooded suction at end, by the material suction lung in suction apparatus.It is easy to the material of suction for some, it is also possible to directly by nose
Son suction.Can be sucked by nasal cavity and can also be sucked by oral cavity for the organ of inhaled material.Lung is sucked by by material
Portion measures, and obtains more preferable measurement effect.It is described as follows：
1st, solid powder requirement has significantly different (being more than or small with the electrical conductivity of the air containing steam in normal alveolar
Yu Junke), the metal dust such as non-metal powder and iron powder such as including carbon dust, is said by inhaled material of solid carbon dust here
Bright, first by carbon dust by the charging apparatus of material access port 3, the heater in 1 position being opened, carbon dust is hollow with 2
Gas mixes.It is to be mixed it is uniform after, flooded suction 6 is directed at tested person's mouth and nose position, controlled valve 4 is opened, by breathing for several times
Continuous lung's electricity laminar analysis measurement in journey, completes the measurement and imaging of lung.
2nd, liquid substance requirement has significant difference (to be more than or small with the electrical conductivity of the air containing steam in normal alveolar
Yu Junke), volatile liquid substance and X 2-1401 (often claiming silicone oil) etc. be not volatile including alcohol etc.
Liquid substance.
Here volatile substances implementation method is illustrated by taking alcohol as an example, alcohol is loaded into dress by material access port 3 first
Put, the heater that will be located at 1 is opened, and air alcohol concentration reaches mixed gas and has with air conductivity in alveolar in treating 2
Visibly different requirement, tested person's mouth and nose position is directed at by device 6, controlled valve 4 is opened, by the company in respiratory for several times
Continuous lung electricity laminar analysis measurement, completes the measurement and imaging of lung.
Here not volatile substances embodiment is illustrated by taking X 2-1401 (hereinafter referred to as silicone oil) as an example, first
By silicone oil by the charging apparatus of material access port 3, the supersonic atomizer of 1 position is opened, silicone oil concentration in air in treating 2
Reach mixed gas has visibly different requirement with air conductivity in alveolar, and flooded suction 6 is aligned into tested person's mouth and nose position, beats
Open switching valve door 4, by the continuous lung's electricity laminar analysis measurement in respiratory for several times, completes the measurement and imaging of lung.
