0 ° of scale of side is overlapped with fixed arm, is checked that scale is equipped with according to range of motion (ROM) on the inward turning plug-in unit graduated scale of joint and is commented
Estimate graticule；
The joint abduction plug-in unit is lower semi-circular angle graduated scale, lower semi-circular angle graduated scale and upper half circle angle
Graduated scale is fixedly connected on the outer side-lower of rotation connection module after being flexibly connected, and the center of circle is 0 ° of scale of side where axle center
It is overlapped with fixed arm, checks that scale is equipped with assessment graticule according to range of motion (ROM) on joint abduction plug-in unit graduated scale.
Preferably, in order to adapt to the limbs of various length, the fixed arm and lever arm are telescopic mounting.
Preferably, the mode that is connected and fixed of the elastic band connects for nylon buckle.
Preferably, in order to which the measurement for adapting to different joints is assessed, joint inward turning plug-in unit and joint abduction plug-in unit are detachable
Formula installation can according to need the plug-in unit for changeing different assessment graticules.
Working principle: then the determination joint to be measured selects corresponding plug-in unit, fixed arm and lever arm are adjusted to suitable
Length is put into the joint to be measured between fixed arm and lever arm, and two elastic bands move in sliding slot to adjust to suitable
Joint motion exception immediate assessment ruler is fixed on the joint to be measured by the velcro fastener on elastic band, then by position
Start inside turning joint, assesses graticule then in the normal range when mobility reaches, not up to or more than assessment graticule be then
Fence coverage.Can also simultaneously outward stir yourself joint, equally see mobility whether lower semi-circular angle graduated scale assessment
Within the scope of graticule line, can judge whether turning joint inner and outer movable degree is normal simultaneously.
The utility model has the advantages that the utility model is provided with assessment graticule compared with the prior art on angle graduated scale, to joint
When measuring assessment, can judge whether turning joint inner and outer movable degree is normal simultaneously, directly assessing joint motion is in just
Normal scope of activities or abnormal ranges, are assessed without compareing measurement table again, can also replace different assessment graticules as needed
Plug-in unit adapt to the measurement in different joints；The utility model structure is simple, easy to carry, easy to use, it is only necessary to which a people can
It is time saving and energy saving to measure, and common patient can also be measured voluntarily.
