As Figure 1-Figure 4, a kind of range of motion measuring device, feature provided by the utility model embodiment
It is: the fixed disk 3 including support frame, operating stick 6 and circular ring shape, circular movable disk 4；
The upper end of support frame as described above is equipped with a universal base 9 that can be rotated upwardly and downwardly, and fixed disk 3 is fixed on universal base 9, living
Moving plate 4 is rotatably mounted on universal base 9, and the pivot center of movable disk 4 is overlapped with the core axis of itself；
The annular diameters of the fixed disk 3 are greater than the diameter of movable disk 4, and fixed disk 3, movable disk 4 are laid with one heart, Gu
A damping ball 5 is equipped in annular space between price fixing 3 and movable disk 4, the damping ball 5 is a flexible sphere,
And damping ball 5 is to roll fit system tight against the inner ring side of firmly fixed disk and the outer circumferential edge of movable disk, the inner ring side of fixed disk
And the outer circumferential edge of movable disk is respectively formed with the guide groove 31,41 rolled for guiding damping ball 5 along the inner ring side of fixed disk；
The corner scale 8 for measuring movable disk rotational angle is printed in the disk of fixed disk 3 or movable disk 4；
The operating stick 6 be one can be along the telescopic rod of the radial expansion of movable disk 4, one end of operating stick 6 and movable disk 4
Affixed, the other end of operating stick 6 is fixed with handle 7.
In the utility model embodiment, support frame as described above includes support base 1, support rod 2, and the support rod 2 is one
The telescopic rod that can vertically stretch, the lower end of support rod 2 are fixed in support base 1, and universal base 9 is mounted on 2 upper end of support rod；This
In utility model other embodiments, support frame can also use the frame body of fixed height, or other height-adjustable frame bodies
(for example the support rod of a regular length is fixed on height-adjustable X-shaped pedestal, form a height-adjustable frame
Body).
The utility model embodiment is suitable for mobility recovery situation after the assessment of patient's Shoulder joint and Shoulder surgery
Assessment, the mobility of shoulder joint can accurately be measured.
When measurement, universal base is rotated upward or downward, so that fixed disk, movable disk enable patient-side pair in state is vertically arranged
Movable disk, and tested shoulder joint makes movable disk 4 towards movable disk, and according to the length of the shoulder height of patient adjusting support rod 2
Core is flushed with patient's shoulder joint, and the length of operating stick 6 is adjusted according to the arm length of patient, and patient is made to be tested shoulder joint one
The arm of side is held handle 7 and is stretched naturally, then enables patient sequentially make the preceding act of arm, rear stretching, extension according to inspection requirements；Also

Right stretching, extension；
When patient's arm is lifted before making, movable disk rotation can be driven by operating stick, and (elastic damping of damping ball is insufficient at this time
To prevent movable disk from rotating), when patient's hand flection to amplitude peak, patient unclamps rear lug, at this time in the elasticity of damping ball
Under damping action, movable disk is stuck and (not can rotate), can pass through the corner scale in the position of operating stick and fixed disk at this time
Measure the preceding act gyration of patient's arm.
Patient's arm make after when stretching, movable disk rotation can be driven by operating stick, and (elastic damping of damping ball is not at this time
It is enough that movable disk is prevented to rotate), when extending to amplitude peak after patient's arm, patient unclamps rear lug, at this time in damping ball
Under elastic damping effect, movable disk is stuck and (not can rotate), can pass through the corner in the position of operating stick and fixed disk at this time
What scale measured patient's arm extendes back angle of tossing about in bed.
When patient's arm makees left stretching, extension, movable disk rotation can be driven by operating stick, and (elastic damping of damping ball is not at this time
It is enough that movable disk is prevented to rotate), when patient's arm left side extends to amplitude peak, patient unclamps rear lug, at this time in damping ball
Under elastic damping effect, movable disk is stuck and (not can rotate), can pass through the corner in the position of operating stick and fixed disk at this time
Scale measures the left stretching, extension gyration of patient's arm.
When patient's arm makees right stretching, extension, movable disk rotation can be driven by operating stick, and (elastic damping of damping ball is not at this time
It is enough that movable disk is prevented to rotate), when patient's arm right side extends to amplitude peak, patient unclamps rear lug, at this time in damping ball
Under elastic damping effect, movable disk is stuck and (not can rotate), can pass through the corner in the position of operating stick and fixed disk at this time
Scale measures the right stretching, extension gyration of patient's arm.
According to the preceding act gyration of the patient's arm measured, extend back angle of tossing about in bed, Zuo Shenzhan gyration, right stretching, extension corner
Degree, it can be learnt that patient is tested the mobility of shoulder joint.
Furthermore it is also possible to universal base be rotated upward or downward, so that fixed disk, movable disk are inclined, then by upper
The method of stating enables patient hold the movement that handle makees outward turning, inward turning, can measure the mobility of several special angles of shoulder joint.
