Abstract

The utility model discloses a protection device for X-ray standing photography of patients, composed of a protection device, a frame, a lifting appliance, a bracket and a base. The utility model has the advantages of simple structure and convenient operation and is arranged between the X ray tube and film when used. The patient is laid between the film and the protection device. The protection device and the line of defence board can be regulated any time according to the different photography sites. The separation distance of the footing can be regulated. The utility model can be matched with various x-ray film hanger brackets.

Description

Protection device for X-ray standing photography of patients

This utility model is a kind of preventer when patient is carried out the photography of the upright position of X ray.This device is arranged between X-ray tube and the X-ray film, when patient is carried out the X ray photography, can greatly reduce the damage of X ray to patient.

The X ray throwing of using at present is a light chopper according to the preventer to patient that machine itself is had, and this light chopper is arranged on the front portion of X-ray tube, and is connected to an integral body with X-ray tube, and the central ray of X ray passes the center of light chopper.When throwing according to chest, owing to need the central ray of X ray to aim at last 1/3 place of chest, patient's non-check point head, cervical region are subjected to a large amount of unnecessary x-ray bombardments.The light chopper of X-ray production apparatus is nearer apart from the X spool, and therefore also relatively poor to the protective capacities of ray at random, patient just is subjected to the damage of a large amount of X ray at random like this.United States Medicine association and U.S. radiology institute warn people will watch out for the irradiation of unnecessary ray to health.Radiation damage has a permanent influence to healthy, and the multiple disease that lonizing radiation cause generally is irreversible.Now domestic do not have dynamical x-ray protection device to be used for patient as yet.

The purpose of this utility model provides the physical protection device that a kind of and X-ray production apparatus separate design, and this device is arranged between X-ray tube and the film, can avoid a large amount of unnecessary X ray and a large amount of X ray at random to the non-check point damage of patient.Significant to people health.

Accompanying drawing 1 is the upright position photography of an X ray patient protection device overall structure sketch map.

Accompanying drawing 2 is the protector internal structure sketch maps on this preventer.

Be described in detail below below in conjunction with accompanying drawing: can find out that from accompanying drawing 1 protector 1 usefulness quadrilateral frame 2 is fixed on the lifter 3, lifter 3 is rectangular pipe, bearing is equipped with as carriage in inside, lifter 3 is placed on the support 4, outer surface at support 4 slides up and down, and is fixed on the arbitrary height position of support 4 with jackscrew knob 5. Be designed with center scale 23 in the front portion of lifter, its most advanced and sophisticated center of aiming at the light inlet window 20 on the protector 1. Steel wire rope 6 on the lifter 3 links to each other with plummet in the stand tube around the fixed pulley 8 on support 4 tops, makes lifter 3 be in poised state. Support 4 is fixed on the center of base 9. Design a plurality of screw holes at regular intervals on the base 9, also a plurality of screw hole at regular intervals on two footing 10, and corresponding with the screw hole of base 9. Footing 10 is connected with base 9 usefulness screws, by different screw holes, can regulate two footing spacings, to adapt to supporting the use of this device and all kinds of photographic film framves.

The internal structure of protector 1 as can be seen from the accompanying drawing 2.Protector is to be made of four limit grooved rails, on last grooved rail 11 and the following grooved rail 12 two vertical defence line plates 15 is housed, and defence line plate 15 adopts the form of coaster 24 to install on last grooved rail 11, can horizontally slip; About the defence line plate 16 of level is housed on two grooved rails 13, the steel wire rope 17 at plate 16 two ends, horizontal defence line is walked around 18, two horizontal defence lines of fixed pulley plate 16 on grooved rail 11 two ends can be by the effect of fixed pulley and slide synchronously in the other direction up and down.Article two, operating grip 19 all is equipped with at the two ends of horizontal defence line, the upper and lower plate 16 of vertical defence line plate 15, and operating grip 19 is exposed to the outside of protector 1, can regulate required throwing according to wild.From accompanying drawing 1 as can be seen the rear wall of protector shell be stereotype, front and rear wall has light inlet window 20, lead rubber 21 is equipped with in the below of protector, stereotype 22 is equipped with in the top.

This utility model can be reducing the unnecessary irradiation to patient to greatest extent, and is significant to the protection people health, thereby remedied the deficiency of light chopper on safeguard function of existing X line machine itself.At present homemade and import medical X ray machine is unmatchful patient's dynamical preventer all.This utility model can with the existing supporting use of all kinds of X ray photographic film frame.

Embodiment: the base of photographic film frame is put between two footing of the present utility model, and protector is between film and X-ray tube, and patient is between film and protector.When taking the chest postero-anterior position, earlier protector is elevated to the support upper end, the central ray of X ray is aimed at patient's fourth dorsal vertebra height, then protector is moved down, make the 30mm place, top at the aligning film center, tip of center scale 23, by shining behind the film size adjusting irradiation field.This utility model also is applicable to takes abdominal part, shoulder, cervical region and all upright position X line photographies.Greatly reduced radiation damage to patient.
