When holding pronate that the second gage beam carries out the forearm, supination activity the operation, can the be accurate convenient angle of reading on the calibrated scale, easy operation, it is accurate to measure, and simultaneously, the device can carry out the measurement of turning up in the foot, and measures the effect and be superior to present joint bevel protractor, and convenient different crowds use in recovered, the teaching of different zone.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, a kind of forearm rotary joint angle measuring scale being applicable to clinical rehabilitation assessment of function and rehabilitation teaching.
Background technology
Recovery function evaluation is by the necessary process of clinical rehabilitation training, and the measurement of range of motion is one of indispensable basic training of rehabilitation professional, is also one of the basic skill of Major study.At present, in clinical rehabilitation assessment of function and rehabilitation teaching process, need to measure range of motion, but existing joint angles protractor can not meet measurement requirement, cause the precision measured low, measurement error easily occurs.
Summary of the invention
This utility model for existing joint angles protractor be not easy to measure forearm rotary joint range of activity, it is provided that a kind of can facilitate forearm rotation before, the forearm rotary joint angle measuring scale of supination angular surveying, in order to improve joint motion measure accuracy.
Realize foregoing invention purpose by the following technical solutions:
A kind of forearm rotary joint angle measuring scale, including angular surveying dish, measure arm, connecting rod, described angular surveying dish is semicircular structure, circumferentially surface indicates the angle index of 0-90 degree, the try to get to the heart of a matter central spot on limit of angular surveying is provided with bearing pin, described measurement arm is divided into the first measurement arm and second to measure arm, first measures arm and connecting rod hinge, the other end of connecting rod and second is measured arm and is connected, first angle measuring arm and angular surveying dish datum line is 90 degree, it is parallel that first measurement arm and second measures arm, the plane that first measurement arm and the second measurement arm are formed is perpendicular with angular surveying panel surface.
Further, described connecting rod is Collapsible structure, is divided into two joints, a joint to hold for fixing, and another joint is for measuring end, and the fixing end of connecting rod and angular surveying dish, the first measurement arm are by hinge, and the measurement end of connecting rod and second is measured arm and connected.
Further, the shortest length of connecting rod is 8cm, and extreme length is 15cm.
Further, during measurement first measure arm and second measure arm be connected as a single entity by connecting rod, jointly rotate.
Further, described angular surveying dish radius is 10cm.
Use technique scheme, compared with current existing joint angles protractor, the beneficial effects of the utility model are: this device for forearm revolve before, the forearm rotary joint angle measuring scale of supination angular surveying, easy to use, simple in construction, it is simple to make；Arm is measured owing to the connecting rod of dip stick connects the first measurement arm and second, angular surveying disk center's point hinge is connected the first measurement arm and is connected with the second measurement arm by connecting rod, angular surveying dish indicates angle index, before holding, when operation, the rotation that the second measurement arm carries out forearm, during supination activity, angle can be read accurately and conveniently on graduated disc, simple to operate, measure accurately, simultaneously, the measurement that this device can turn up in carrying out foot, and measurement effect is better than existing joint angles chi, facilitate different crowd in community-based rehabilitation, hospital rehabilitation, school's rehabilitation teaching uses.
Accompanying drawing explanation
Fig. 1 is this utility model main TV structure schematic diagram when opening.
In figure: angular surveying dish 1, angular surveying disk center's point 2, connecting rod 3, first measures arm 4, and second measures arm 5.
Detailed description of the invention
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
This forearm rotary joint angle measuring scale disclosed in the present embodiment is by angular surveying dish 2, connecting rod 3, and first measures arm 4, and second measures arm 5 forms.Concrete structure sees accompanying drawing 1.
The angular surveying dish 1 of the present embodiment be radius be 10cm likeness in form protractor semicircular structure, angular surveying dish 1 circumferentially surface indicates the angle index of 0-90 degree, the center scale of angular surveying dish 1 is 90 °, and both sides datum line is 0 °, in order to meet forearm rotation before, the measurement requirement of supination.Angular surveying try to get to the heart of a matter limit (datum line) central point 2 at bearing pin is installed.
Measuring arm is divided into the first measurement arm 4 and second to measure arm 5, and first measures arm 4 and connecting rod 3 hinge, and connecting rod 3 is Collapsible structure, being divided into two joints, coaxial rotating, a joint is fixing end, another joint is for measuring end, and time flexible, shortest length is 8cm, and extreme length is 15cm.The fixing end of connecting rod 3 and hinge, the measurement end of connecting rod 3 and second is measured arm 5 and is connected.First measures arm 4 parallels with the second measurement arm 5, and first measures arm 4 and second measures plane and the perpendicular of angular surveying dish 1 that arm 5 is formed.The the first measurement arm 4 and the second measurement arm 5 that connect by connecting rod 3 during measurement are integrally forming, and jointly rotate, complete to measure purpose.
Using method of the present utility model:
In order to reach the purpose measured accurately, be convenient for measuring, second measures arm 5 measures arm 4 coaxial rotating by connecting rod 3 and first, first measures arm 4 can read angle index easily on angular surveying dish 1, measure the distance between arm 5 for the ease of operation the first measurement arm 4 and second, measure arm 5 with palm grip second and carry out rotary moveable.
Measuring for convenience, the center scale of angular surveying dish 1 is 90 °, and both sides datum line is 0 °, can meet forearm rotation before, the measurement requirement of supination.Before measuring forearm rotation, the range of motion of supination time, the first original position measuring arm 4 and the second measurement arm 5 is placed in 90 ° of positions, when turning up in being used for measuring foot, is placed in 0 ° of position.
