Abstract
The utility model relates to an x-ray dislocation photography positioning scale for trachea and bronchus. A vertical column 2 which is connected with a cross arm 4 and an angle board 3 is arranged on a base 1; the angle board 3 is provided with an angle pointer 6. The utility model which has the advantages of simple structure and convenient use can accurately cause the plane of the trachea and bronchus system to be parallel with the bed surface of photography. Thus, the trachea, a primary bronchus, and a foliage bronchus can be clearly displayed on a same dislocation sheet.
Description
This utility model relates to a kind of medical positioner that person's windpipe, bronchus is carried out x-ray tomography.
At present, trachea, bronchus tomography, X line technician still uses angle box bed hedgehopping patient buttocks waist by rule of thumb when the location, make human body coronalplane and photography bed surface be 15～20 degree angles, realizes that trachea, bronchus are that particular plane is parallel with the photography bed surface.Because institute's angle of fill up is inaccurate, on taking the photograph laminagram, the nearly section of trachea, main bronchus shows when knowing often, and trachea, main bronchus section far away and the demonstration of leaf bronchus are unclear, and when latter's demonstration was known, the former showed unclear again.
The purpose of this utility model is accurate localized device when a kind of trachea, bronchus tomography will be provided, and reduces the personal error of tomography, makes the trachea on the laminagram of taking the photograph, main bronchus and leaf bronchus all can know demonstration.
This utility model is established a base, and a column is arranged on the base, and column is vertical with base, establishes a transverse arm on the column, and transverse arm is vertical with column, and can be on column up-down adjustment, the other end of transverse arm has angle board, and angle indicator, adjustable-angle are arranged on the plate.
Application this utility model positions, can make person's windpipe, bronchus exactly is that particular plane is parallel with the photography bed surface, avoided in the present localization method, a certain angle in bed hedgehopping 15～20 degree angle ranges, and can't judge that whether this angle can make person's windpipe, bronchus is that particular plane is parallel with the photography bed surface, thereby improved the tomography success rate greatly, reduced film waste, reduced patient's radioactive dose.
Stereochemical structure of the present utility model is seen accompanying drawing.1 is the positioning rule base among the figure, and 2 is column, and 3 is angle board, and 4 is transverse arm, and 5 is 2 and 4 the knob that is connected and fixed, and 6 is the angle indicator on the angle board, and 7 is the angle indicator adjusting knob.
Implementation example: measure the trachea surface angulation a corresponding from patient's chest lateral radiograph earlier with presternum, adjusting angle plate upper knob 7, make pointer 6 become a angle with angle board right side 0 graduation mark, allow the patient lie on the back on the photography bed, median sagittal plane is aimed at photography bed surface center line and vertical bed surface, and positioning rule places on the bed surface of patient's chest left side, makes transverse arm 4 vertical with patient's sagittal plane, adjusting knob 5 makes angle board lower edge mid point directly over patient's sternal angle mid point.Bed hedgehopping patient buttocks waist makes the surface of presternum correspondence parallel with angle indicator 6 then.X line centrage is aimed at the sternal angle mid point.Like this, patient's trachea, bronchus are that particular plane is promptly parallel with the photography bed surface, and finish the location.
