Abstract
The invention relates to a rotating arm of an economical X-ray photography system; one end of the rotating arm is provided with a detector fixing device and the other end thereof is provided with a bulb pulley guide rail, and a rotating shaft installation hole of the rotating arm is arranged on one end which is close to a detector. Wherein, the rotating arm is processed and manufactured by a standard profile rectangular tube, and a rotating center, i.e. the rotating shaft installation hole is close to the end of the detector; because the weight of the detector is much heavier than the total weight of a bulb beam splitter component and a bulb pulley, at a vertical position, when SID is a special value (a value commonly used in a horizontal position, i.e. SID=1m), the torque of the detector relative to the rotating center can be balanced with the torque of the bulb beam splitter component and the bulb pulley relative to the rotating center, and no counterweight needs to be added. At this time, the rotating arm can be easily rotated so as to realize the conversion from the vertical position to the horizontal position.
Description
Technical field
The invention provides a kind of turning arm of economical X-ray photography system, especially a kind of cost of manufacture is low, the turning arm of the rotation of turning arm and the more portable economical X-ray photography system of lifting.
Background technology
Along with digital technology now in medical radiation equipment, not only makes imaging digital in the widespread usage of all trades and professions, but also make the motion on all directions also realize Digital Control, improved medical worker's work efficiency greatly.But simultaneously, also make our radiological installation price heighten, and stability is a long-standing problem of digitalization radiation equipment.Along with China's medical treatment policy reform, the environment of village layer medical mechanism and equipment need to be resolved hurrily and improve.Occurred economical digital irradiation photography system thus, this system all adopts manual operation, is mainly used in to take upright (people stands between detector and the bulb light concentrator assembly) and clinostatism (people lies between detector and the bulb light concentrator assembly).With low cost, simple to operate, can improve medical worker's work efficiency greatly, be the first-selection film making equipment of the village layer medical mechanism of shortage of funding.The main member of this equipment is a turning arm, and core component detector and bulb light concentrator assembly are installed on it.
The X ray camera chain structurally has various ways, common have two kinds on U-shaped arm configuration and a suspension structure, and in recent years, appearance along with the big policy of country, the reform of primary care is imperative, thus, on the basis of above-mentioned two kinds of structures, derive simpler and easy, more cost effective X line camera chain.Wherein a complete manual straight-arm structure of being derived out by the U-shaped arm is illustrated in fig. 1 shown below.
Its relation of installing is: lifting tube 4 is installed on the column 7 by steel wire rope or synchronous band, and can carry out the oscilaltion campaign on column 7; Rotating shaft 3 is fixed on the lifting tube 4, and it can carry out in the oscilaltion campaign with lifting tube 4 on the one hand like this, can be rotated around self axis on the other hand; Turning arm 2 installs and fixes together with rotating shaft 3, and it can realize two same motions with rotating shaft 3; Detector 1 is fixed on an end of turning arm 2; Bulb coaster 5 is installed in the other end of turning arm 2, can carry out rectilinear motion on turning arm in the certain distance; Bulb light concentrator assembly is fixed on the bulb coaster, its light-emitting window and detector dash receiver keeping parallelism, and center unanimity.
The function of this system is simplified to having only upright position and two kinds of functions of clinostatism, and its operation principle is: patient lies on the photography bed, manually rotates 2 to 90 ° of positions of turning arm (clinostatism), makes detector 1 be positioned at the roughly position at 30mm place, bed panel below; Promote the photography bed, the captured position of patient is on bulb focus and the detector 1 sensitive surface central vertical line.Perhaps manually rotate 2 to 0 ° of positions of turning arm (upright position), it is position shown in Figure 1, patient stands between detector 1 and the bulb light concentrator assembly 2, slip bulb coaster, can adjust the distance between detector 1 and the bulb light concentrator assembly 2, be that (1m～1.8m) is to take patient's different parts for SID.The x-ray that penetrates from bulb passes patient's lesions position and beats on the detector dash receiver after light concentrator is regulated the light open country like this, after digital processing, generate the image of lesions position on work station, thereby the doctor can provide a diagnostic result.
Wherein, turning arm 2 is core components of realizing that clinostatism and upright position are changed.In the product abroad, the position of detector 1 is not fixed, and it can carry out the synchronous linear motion with bulb light concentrator assembly 6 in the certain distance of turning arm 2 one ends, to realize the equalising torque of two ends with respect to rotating shaft 3, thereby when clinostatism is operated, reach the labour-saving purpose by upright position.
At home in the product, the position of detector 1 is fixed (as shown in Figure 1), as SID during in certain numerical value, detector 1 end and bulb light concentrator assembly 6 ends are with respect to rotating shaft 3 centrosymmetry on the turning arm 2, add balancing weight to realize the equalising torque of two ends by arm intracavity then with respect to rotating shaft 3 at bulb light concentrator assembly 6 ends, thereby when clinostatism is operated, reach the labour-saving order by upright position.
The prior art shortcoming
1, in the external product, because the position of detector 1 is not fixed, it is processed with bigger difficulty to the making and the requirement of strength height of turning arm 2, and technology also has difficult point.Increased cost virtually.
2, in the home products, by adding counterweight (generally being lead) with the two ends balancing, the one, increased noxious substance (lead); The 2nd, job costs also higher (the current 25RMB/kg of lead).
Summary of the invention
The present invention is continuing to use on the fixed architecture basics of position of detector, turning arm and bulb coaster are done some simple structure accommodations, it is a kind of can reducing production costs greatly, and the turning arm of the rotation of turning arm and the more portable economical X-ray photography system of lifting.
