Abstract

The utility model relates to a multifunctional body thickness rule, belonging to the technical field of medical appliances, which comprises a square, a first slide gauge and a second slide gauge, wherein the first slide gauge is perpendicular to the AB side of the square, and is parallel to the BC side thereof, the first slide gauge can slide up and down along the AB side of the square, and the second slide gauge is perpendicular to the AB side and the BC side of the square, also can slide up and down along the AB side of the square, and can be freely detached, and the surface of the second slide gauge can be horizontally placed, wherein the length of the AB side is 40-50cm, and the lengths of the first slide gauge and the second slide gauge are about 20cm-30cm. The multifunctional body thickness rule has complete function, convenient use and accurate measurement.

Description

The thick chi of a kind of multi-functional body

Technical field

This utility model belongs to the radiotherapy positioning equipment, the thick chi of especially a kind of multi-functional body.

Background technology

Radiotherapy is the effective means of treatment malignant tumor, and the World Health Organization's malignant tumor patient of report more than 70% need be used radiotherapy.The thick chi of body is widely used in the radiotherapy location, and orientation tool is absolutely necessary.It is that to measure body thick, determines the important tool of body surface irradiation field size and the position and the target area degree of depth.Radiocurable enforcement is to use positioning rule or simulated positioner by the location target area to be manifested accurately and be marked at body surface according to image data, promptly forms corresponding irradiation field, again linear accelerator or cobalt-60 therapy machine head is aimed at irradiation field and implements treatment.And the positioning rule of generally using at present (thick chi of body and ruler), 1. usage is single, the thick chi of body only can measure the relative position that the thick and ruler of body can only be measured the size of irradiation field or be measured irradiation field, if it is thick or measure the size of irradiation field with positioning rule to measure body with ruler, should use the clumsy trouble of comparison, and accuracy is not high and then influence the size and the irradiation field relative position of irradiation field, and has influence on the thick accuracy of gauge of body.2. measure patient's body when thick with the thick chi of common aspect in patient's dorsal position, need patient's body to be raised or stood and the more fixedly galianconism of the thick chi of common aspect is placed health bottom, thereby lost the uniformity of position, and increased the stimulation of metal pair skin in the winter of cold, made patient feel very uncomfortable.3. the thick chi of common aspect can only not have any help owing to do not have rule on its sliding bar as measuring the thick instrument of body when determining the position of irradiation field when head is located.

Summary of the invention

The purpose of this utility model is to provide a kind of can measure that body is thick can work as the thick chi of body that ruler uses again, particularly determines to have special effect to what dorsal position was measured the thick and head irradiation field of body.

The purpose of this utility model is achieved in that the thick chi of a kind of multi-functional body, is made up of square, first slide rule, second slide rule, and wherein, first slide rule is vertical with the AB limit of square, and is parallel with the BC limit, and first slide rule can slide up and down along the AB chi of square; Second slide rule is all vertical with the BC limit with square AB limit, and second slide rule also can slide up and down along the AB chi of square, and can freely dismantle the horizontal placement of its chi face; AB length of side 40-50cm, first slide rule and second slide rule are about 20cm-30cm.

Using this utility model to measure body has when thick characteristics 1. to stand or first slide rule that the seat patient body can adopt square and slide up and down along the AB chi when thick when measuring; And it is thick to be fit to measure the body of supine patient with the combination of square and second slide rule, avoided patient body is raised the bottom that again the BC limit of square is put in patient body, get final product but base BC is put on the bed surface of patient's one side, avoided influencing the thick accuracy of body, avoided the stimulation of ruler in the winter of cold skin owing to the variation of patient posture.2. first or second slide rule being torn open the next ruler that all can be used as arbitrarily makes and is used for measuring the size of irradiation field or the relative position of definite irradiation field.3. when the irradiation field of definite head side, use the square and first slide rule and square base BC be put in CT or magnetic resonance imaging baseline, first slide rule along square AB slide up and down and above generation the scale that has determine the size and the position of irradiation field; And when measuring the position of head irradiation field, first slide rule pulled down be enclosed within again on second slide rule, can determine the size and the lesion locations of head irradiation field like this.

This utility model is multiple functional, easy to use, measurement is accurate.

Description of drawings

Accompanying drawing is this utility model structural representation.

Wherein: 1, square 2, first slide rule 3, second slide rule

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing, and the thick chi of a kind of multi-functional body is made up of square 1, first slide rule 2, second slide rule 3, wherein, first slide rule 2 is vertical with the AB limit of square 1, and is parallel with the BC limit, and first slide rule 2 can slide up and down along the AB chi of square 1; Second slide rule 3 is all vertical with AB, the BC limit of square 1, and second slide rule 3 also can slide up and down along the AB chi of square, and can freely dismantle the horizontal placement of its chi face; AB length of side 40-50cm, the long all about 20cm-30cm of two slide rules.
