Abstract
A measurement device used for measuring intravital joint angles comprises a fixed arm and a rotating arm, one end of the fixed arm and one end of the rotating arm are connected via a rotating shaft, a protractor utilizing the rotating shaft as the circle center is fixedly arranged on the fixed arm, the protractor is provided with scales and is a semicircular plate utilizing the rotating shaft as the circle center, one end of the semicircular plate is fixed on the fixed arm, and the diameter of the inner circle of the semicircular plate is larger than 3cm. As the fixed arm and the rotating arm are connected via the rotating shaft and the protractor is fixed on the fixed arm, the measurement device is a combination of a pair of compasses and the protractor, and can conveniently measure angles of joints stopped after movement. Simultaneously, lengths of the fixed arm and the rotating arm can be adjusted according to needs, so that the measurement device can be used for measuring angles of large and small joints. In addition, the measurement device is simple in structure and convenient in use and carrying.
Description
Technical field:
This utility model relates to physical field, relates in particular to angle measurement unit, particularly a kind of measuring device that is used to measure the live body joint angles.
Background technology:
In the prior art, the various gages in the somatometry all center on measurement length and width carries out, and representative have Martin's chi (suit), slide gauge (suit), up-to-date Japan produce length gage (suit).The bent angle that adopts on domestic clinical medicine rule are that to be used for measuring shoulder breadth, pelvis wide etc.Lack the portable gage of measuring the joint motion angle, have also as on " wait test instrunment---SYBIX " instrument and equipment medically, utilize the limb rotation in fixing big joint, rotate input data to computer by unit head and show the joint motions angle; And, discern the joint motions angle by image analysis software in the sport biomechanics field, expense costliness, practical operation are easy inadequately.
Summary of the invention:
The purpose of this utility model is to provide a kind of measuring device that is used to measure the live body joint angles, the described this measuring device that is used to measure the live body joint angles will solve the activity point of view that gauge of the prior art is not easy to directly measure the joint, and the technical problem that adopts image analysis method cost height, is not easy to carry.
This measuring device that is used to measure the live body joint angles of the present utility model, comprise fixed arm and cursor, wherein, one end of described fixed arm and cursor is connected by rotating shaft, also being set with one on described fixed arm is the protractor in the center of circle with described rotating shaft, and described protractor is provided with scale.
Further, described protractor is to be the semicircle ring flat-plate in the center of circle with described rotating shaft, and an end of described semi-round ring shape plate is fixed on the described fixed arm, and described semicircle ring flat-plate is provided with scale.
Further, the radius of the inner ring of described semicircle ring flat-plate is greater than 3 centimetres.
Further, the length of described fixed arm and cursor is 15～20 centimetres, and diameter is 0.2～0.4 centimetre.
Further, be arranged with extension arm in described fixed arm and the cursor, be provided with sliding pair between described extension arm and described fixed arm and the cursor, the length of described extension arm is 30 ~ 100 centimetres.
Operation principle of the present utility model is: fixed arm and cursor are the center of circle with the joint center of rotation, can directly read the number of degrees of joint motions when stopping.Fixed arm and cursor can prolong as required, shorten, and around center of circle angles of display, can be used for the angular surveying in big or small joint.
This utility model is compared with prior art, and its effect is actively with tangible.This utility model is connected with cursor fixed arm by rotating shaft, also be fixed with protractor on fixed arm, and compasses and protractor are combined, and can measure the angle of joint motions when stopping easily; The length of fixed arm and cursor can be adjusted as required simultaneously, can be used for the angular surveying in big or small joint; This angular surveying device is simple in structure, easy to use, is easy to carry.
