Abstract
The utility model provides a back-screen shielding dark room for the technical field of medical equipment. The utility model is characterized in that the inner side of an original dark room is additionally provided with a lead containing filtering layer; the inner surface of an aluminum filtering layer is provided with a spongy layer. Compared with the existing dark room, the utility model which can generate shielding effect to X-ray has the advantages of radiation protection enhancement, harm to operators reduction, etc.
Description
This utility model belongs to technical field of medical instruments, is a kind of back of the body screen protected type camera obscura.
The common X-ray diagnosis is the basic methods of medicine and health work.In this work, the spot film of gastrointestinal barium meal is again a requisite project.And this work is important link in the radiation protection work.This work is done in the big portion source of the suffered radiation dose of radiologist.It wants reason is that camera obscura must place the operator front, and camera obscura can not produce shielding action to X ray simultaneously.
The purpose of this utility model provides and a kind ofly can produce shielding action to X ray, to strengthen radiation protection, reduces the camera obscura of operator's harm,
Technical solution adopted in the utility model is improved on the basis of original camera obscura, has additional plumbous filter course in the back of the body screen inboard of original camera obscura, sets up spongy layer at the inner surface of plumbous filter course.
Because this utility model has been taked technique scheme, compares with existing camera obscura, have and can produce shielding action X ray, to strengthen radiation protection, reduce advantages such as harm to the operator.
Below in conjunction with accompanying drawing and example, specific structural features of the present utility model is described further.
Fig. 1 represents general assembly structural representation of the present utility model.
As shown in the figure, the utlity model has header board 1 and back of the body screen 2, header board 1 inboard is lined with intensifying screen 3, and back of the body screen 2 is connected with header board 1 by hinge 4.Arranged outside at back of the body screen 2 has buckle 5, and the frame of header board 1 is provided with draw-in groove 6.Its main feature is in the inboard of back of the body screen 2 plumbous filter course 7 to be set, and the plumbous filter course 7 of this layer can adopt lead glass, and the inner surface of this layer lead glass can adopt matte surface, sets up spongy layer 8 at the inner surface of this lead filter course 7.This lead filter course is not more than 2 millimeters thick and is advisable to be no less than 1 millimeter.
