The other X-ray machine of a kind of high frequency bed
Affiliated technical field
The present invention relates to a kind of technical field of medical instruments, be a kind of small-size multifunction X-ray machine.
Background technology
At present, the X-ray machine that is widely used both at home and abroad mostly is the power frequency X-ray machine, its structure is made up of X ray tube and high voltage power supply two parts, the X ray tube is installed on the framework of machinery, utilize machinery or steel wire rope transmission, the X ray tube is moved arbitrarily on vertical plane, be characterized in bulky, heavy especially, from technology, poor image quality, exposure accuracy are low, automaticity is low, protection level does not all reach specification requirement, especially to having the patient of epidemic situation, brings great inconvenience as the atypical pneumonia patient during use.
Summary of the invention
For solving the deficiency of above X-ray machine structure, purpose of the present invention provides a kind of high frequency bed other X-ray machine, utilizes the multifunctional small-size structure, the employing frequency is that the high-frequency and high-voltage camera work of 100KHz is in light weight to realize, conveniently moving, easy and simple to handle, be applicable to the other purpose that detects of bed.
The structural design of X-ray machine of the present invention is achieved in that other its structure of X-ray machine of high frequency bed is by column, rotating seat, sliding seat, the cant beam support arm, pulley and steel wire rope, high-frequency and high-voltage generator, mobile go-cart assembly and bulb and beam-defining clipper are formed, its connection is to be fixed on before and after high-frequency and high-voltage generator and the column in the mobile go-cart of band universal caster wheel (as shown in Figure 1), on vertical column, slide is housed, adopt pulley and steel wire rope to connect between slide and the column, small-sized counterweight is housed simultaneously, on slide, be fixed with the cant beam support arm, the pulley outer housing is equipped with on the top, the column mid portion has spacing hole, and base moves rotating shaft assembly is housed between the go-cart, realize ± 180 ° of rotations, the X ray tube is equipped with on cant beam support arm top, adopt rotary sleeve to connect between cant beam support arm and the bulb with electromagnet structure, the power supply of bulb is by the cant beam support arm, column connects with high-frequency and high-voltage generator, be fixed with beam-defining clipper below the bulb, be placed with the magazine of disposable antisaprobic zone film on the corresponding diagnostic bed of bulb and beam-defining clipper, control panel is housed on high-frequency and high-voltage generator, link to each other with the high-frequency and high-voltage generator main body by a metal housing, also have exposure handle and emergency stop switch on this high voltage control platform.
The present invention's advantage: simple in structure, adopt alternating current 220V general lighting power supply, in light weight, conveniently moving, easy and simple to handle, be suitable for bedside and detect; Product price is cheap; Can continuously carry out 200 rabats and take diagnosis in one hour, be suitable for doing " epidemic situation patient " special-purpose equipment of popularizing, maximum characteristics reduce cross infection, make a definite diagnosis fast, in time treatment.
Description of drawings
Fig. 1 is the other X-ray machine structure principle chart of high frequency bed,
Among the figure: 1 bulb (band control box), 2 beam-defining clippers, 3 cant beam support arms, 4 columns, 5 high-frequency and high-voltage generators, 6 move go-cart, 7 pulley outer housings, 8 spacing holes, 9 disposable anti-pollution film cassettes.
The specific embodiment
This X-ray machine is the small-size multifunction X-ray machine, the NSX-M300 type, adopting bulb (band control box) is RAD12, component heat capacity 150kHU, focal spot size: little focus 0.6mm, large focal spot 1.2mm, inherent filtration 1.5mmAl, type of cooling natural cooling, pillar construction, the distance of bulb focus stroke: about 750mm, the optional position locking, the bulb focus is 1850mm apart from level ground ultimate range, minimum range is 1100mm, the distance of X line machine bulb focus stroke is: 600--1300mm, and the beam-defining clipper type of drive: manually, irradiation field: rectangle, visual field indication average illumination: greater than 120Lux, inherent filtration: 1.0mm (equivalent thickness of aluminium), added filtration: 0.5mm (equivalent thickness of aluminium) is when this machine uses, mobile go-cart by foot wheel moves to bedside, carries out diagnostic operation by the exposure handle on the control panel again.
How this machine is avoided aspect " epidemic situation patient " and medical personnel's the cross infection, has carried out the design of showing ingenuity, and the disposable anti-pollution magazine cover of its particular design prevents cross infection; Have the disposable machine clothing of particular design, avoid cross infection; This machine has adopted special surface, and whole shell reduces and pollutes, and is convenient to sterilization.
