Abstract
The utility model discloses a cardiothoracic radio measuring ruler for a medical X-ray photograph, which is the measuring instrument for the medical X-ray photograph. The cardiothoracic radio measuring ruler for a medical x-ray photograph is characterized in that: the value shown by the intersection of the oblique line and a straight ruler is the cardiothoracic ration value of the sternite to be measured. The measuring ruler has the advantages that the reading is accurate, the calculation is not needed and the photograph can not be contaminated; the cardiothoracic radio measuring ruler for a medical X-ray photograph has easy manufacture and low cost, and is suitable for the volume-production.
Description
Technical field
The utility model relates to a kind of medical X-ray photo survey instrument, particularly relates to a kind of medical X-ray photo cardiothoracic ratio dip stick.
Background technology
Present survey instrument used in everyday has ruler, set square, tape measure etc., mostly be simple function, clinician and radiologist often make mark and then measure transverse thoracic diameter and cardiac broad diameter with ruler with the stroke line on the X exograph X when measuring cardiothoracic ratio, by calculating cardiothoracic ratio.This method is marked owing to ruling on photo, and comparison film pollutes and cut, is unfavorable for the preservation of image data, and with still calculating after the ruler measurement, bigger error often occurs, is unfavorable for the accurate diagnosis to disease.Therefore, vast clinical medical personnel is starved of a kind of photographic quality that do not influence, and accuracy of reading is directly perceived, novel dip stick easy to use.
Goal of the invention
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of simple in structure, easy to use, medical X-ray photo cardiothoracic ratio dip stick that accuracy of reading intuitively and not influences photographic quality is provided.
Summary of the invention
The purpose of this utility model is achieved in that
Medical X photo cardiothoracic ratio dip stick is the isosceles right triangle structure, is made of horizontal line, oblique line part and ruler two parts.Horizontal line has more than two and spacing distance equates, is mainly used in the measurement of thorax and cardiac broad diameter.Oblique line is the line of the full section of each Duan Zhanqi of every horizontal line respective value by the same acute angle point of triangle, but it and horizontal acting in conjunction are deixis cardiothoracic ratio numerical value.Ruler can directly be measured the size of blood vessel, tracheae caliber and other focus, and its subscript is shown with scale and cardiothoracic ratio value.
Use the utility model both to can be used for the measurement of chest and lung's plain film focus and blood vessel, tracheae caliber, also can be used for the measurement of other position pathologies and the measurement of cardiothoracic ratio.The utlity model has do not pollute photo, directly reading, need not calculate and registration advantage accurately, be clinician and the desirable survey instrument of the diagnostician of dept. of radiology.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing, 1 is horizontal line, and 2 is oblique line, and 3 is ruler, and 4 is scale value, and 5 is the cardiothoracic ratio value.
Embodiment
The contrast accompanying drawing describes in further detail the utility model below.
A kind of medical X photo cardiothoracic ratio dip stick is the isosceles right triangle structure, is made of horizontal line 1, oblique line 2 parts and ruler 3 two parts; Wherein said horizontal line 1 has more than two and spacing distance equates, is mainly used in the relative size of measuring transverse thoracic diameter and cardiac broad diameter.
Described ruler 3 subscripts are shown with scale value 4 and cardiothoracic ratio value 5, can directly measure the size of blood vessel, tracheae caliber and other focus.
Described oblique line 2 is the full section of each Duan Zhanqi of every horizontal line respective value lines by the same acute angle point of triangle, but the acting in conjunction of it and horizontal line 1 is a deixis cardiothoracic ratio numerical value; Described oblique line 2 has more than two; Wherein every oblique line 2 has all indicated ambition rate value 5 with the intersection point of ruler 3, and the cardiothoracic ratio value 5 shown in this intersection point is this oblique line 2 corresponding cardiothoracic ratio numerical value.
Embodiment:
With the cardiothoracic ratio that utilizes the utility model to measure a plain chest film is that example describes.
Getting a plain chest film is inserted on the viewbox, measure transverse thoracic diameter with the horizontal line on the utility model 1, find out wherein horizontal line 1 isometric with transverse thoracic diameter, and then begin to remove to measure cardiac broad diameter to the right side by the left end of this chi with this horizontal line 1, point has the corresponding oblique line 2 of bar shown in the cardiac broad diameter maximal value, and this oblique line 2 is the cardiothoracic ratio numerical value that this rabat will be measured with the pairing cardiothoracic ratio value 5 of intersection point of ruler 3.
