Description

Thermo-scan image system-specific bed

This utility model relates to the thermo-scan image system characteristics of utilizing, in the medical image technology frontier of opening up based on function assessment, as the usefulness of the accuracy rate of diagnosis that improves this thermo-scan image system.

Utilize this system to catch the thermal radiation information of metabolism of human cell process, scan according to the caloradiance of being examined the position cellular metabolism and be integrated into picture, machine is handled as calculated again, and the various pathological changes of human body are carried out qualitative and Differential Diagnosis; Particularly safety is big, there is not the damage of intervention, no external source radioactive radiation, the efficient height, especially health screening and early diagnosis, general crowd's health status generaI investigation, high-risk group's the generation of making regular check on ischemic pathological changes such as early stage indication myocardial infarction, cerebral infarction, accurately the inflammation at positions such as diagnosis thyroid, mammary gland, prostate and skeleton or canceration observation of curative effect and check are followed the trail of, chemotherapy of tumors or radiotherapeutic effect are assessed multiple measuring abilities such as the recurrence of monitoring malignant tumor and transfer case.Therefore at home and abroad progress is rapid in recent years, obtains increasing expert and payes attention to, and the instrument production of thermo-scan image system is all arranged both at home and abroad; But present known domestic and international traditional method, all be that the upright position of examinee is scanned, so not only owing to the subject movability influences picture quality, particularly owing to reasons such as the labyrinth of human body and the power of directly surging, in addition from the thermal information of inside of human body, it is not tailored radiation, conduction is arranged equally, convection current, three kinds of forms of radiation, its surface temperature height is subjected to amount of sweat and influence of evaporation too, especially the convection current of temperature in the body, the part that temperature is high always makes progress, the rich blood vessel position more so, domestic many experts also advise changing upright position and are clinostatism, to collect how useful thermal information, increase degree of analysing clearly, find ND pathological changes, improve accuracy rate of diagnosis.Because of its projection path can not have any overcover, add some other specific (special) requirements, so have not yet to see the report that is fit to thermo-scan image system-specific bed.

The purpose of this utility model is to solve examinee's clinostatism, can make again between photographic head and the examinee can all around, easy on and off control is moved, particularly can be between human body and photographic head, under situation without any covering, position during examinee's clinostatism, can arbitrarily control, can make any degree angle change.

This utility model is achieved in that at angle steel and constitutes on the basis of framework, by three motors and variator thereof and gear by column and slide rail, control respectively photographic head do about, the moving of all around.By a motor by gearing in transmission levers, drive canvas conveyor type bed surface, make subject face photographic head and do various different angles conversion, to be fit to the needs of various different check points.

This utility model is owing to adopted new structure and the novel linear electric motors and the canvas conveyor type bed surface of colloidality coating in addition, so very convenient to the clinostatism inspection.

Below with reference to accompanying drawing utility model is done and to be described in further detail.

Fig. 1 is an overall operation part sketch map of the present utility model.

Fig. 2 is an end face operation part sketch map of the present utility model.

This utility model is made of bed body rack (10) photographic head column body (12) and its base (11) and drive mechanism, (3) three parts of colloidality coating canvas conveyor type bed surface.Bed body rack is made up of channel-section steel, angle steel and square body and steel plate (23) fixed screw (24); Photographic head column (12), base (11) and drive mechanism are made up of driving motor (6) deceleration coupling wheel (7) operation wheel (8) respectively; Photographic head column body (12) is by linear electric motors (18) (15) and straight line catch bar (19) (13), pulley (14) suspension wire rope (17), and the bar hole (16) of balance metal derby (9) and rustless steel outer housing is formed; The canvas conveyor type bed surface (3) of colloidality coating drives two ends by reducing motor (4) coupling axostylus axostyle (5) and the driving shaft (2) of bearing, middle processing grooving body and driven axle (1) that bearing is equipped with at two ends is housed and scribbles special canvas conveyer belt (3) anti-skidding and firm attrition resistant rubber and formed, thereby has constituted the angular transition system.

During inspection, those who are investigated's face or crouch on the canvas conveyor type bed surface (3) of colloidality coating back to photographic head (20), start motor (6) then and drive operation wheel (8) by tubulose garden type track (21) (22) by reduction gearing axostylus axostyle (7), base (11) the drive photographic head (20) of photographic head is moved reciprocatingly by the subject major axis, behind the selected desired area, start again about control linear electric motors (18), driving photographic head lever (19) makes photographic head (20) do side-to-side movement, after choosing the position, start linear electric motors (15) more on request and move up and down by straight line catch bar (13) drive photographic head (20), operation is identical about this linear electric motors operation principle and control.Different is that linear electric motors catch bar (13) is fixing, and linear electric motors (15) drive photographic head (20) move up and down, so that the distance between selected subject surface and the photographic head.Its effect of pulley (14) suspension wire rope (17) balance metal derby (27) is to make weight balancing, to reduce straight line catch bar (13) resistance up and down; Have in an end of photographic head lever (19) and photographic head (20) junction fixedly that keyhole (25) and side opening (26) can change the photographic head direction easily, so as with the usefulness of traditional upright method for position contrast.If when in inspection, needing different angles, reducing motor (4) can be started and the canvas conveyer belt bed surface (3) that has colloidality coating can be made by coupling axostylus axostyle (5) drive driving shaft (2) and driven axle (1), move reciprocatingly, because it has the concavity of bedside radius, so subject can rotate with reciprocating motion, thereby make between subject and the photographic head (20), under the situation of no any covering, can reach any angle of selecting between positive and negative 360 degree, to select various different angles, the while reaches again and makes the upwards purpose vertical with photographic head of subject surface.
