Abstract
A forearm rotation joint angle measuring scale comprises an angle measuring plate, measuring arms and a connecting rod, wherein the angle measuring plate adopts a semicircular structure, and is marked with 0-90-degree angle scales along the circumferential surface; a pin shaft is mounted at a central point of the bottom side of the angle measuring plate; the measuring arms comprises a first measuring arm and a second measuring arm respectively; the first measuring arm is hinged to the connecting rod through the pin shaft; the other end of the connecting rod is connected with the second measuring arm; the included angle between the first measuring arm and a reference line of the angle measuring plate is 90 degrees; the first measuring arm and the second measuring arm are parallel; a plane formed by the first measuring arm and the second measuring arm is vertical to the plane of the angle measuring plate. During operation, when the second measuring arm is held by a hand for performing pronation and supination of a forearm, the angle can be accurately and conveniently read out on a scale plate, so that the operation is simple and measurement is accurate; meanwhile, the forearm rotation joint angle measuring scale can measure introversion or extroversion of a foot, has a measurement effect better than that of the existing joint angle scale, and facilitates rehabilitation and teaching of different people in different regions.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of forearm rotary joint angle measuring scale imparted knowledge to students suitable in clinical rehabilitation assessment of function and rehabilitation.
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, it is necessary to measure range of motion, but existing joint angles protractor can not meet measurement requirement, cause that the precision measured is low, it is easy to measurement error occurs.
Summary of the invention
The present invention is directed to existing joint angles protractor and be not easy to measure the range of activity of forearm rotary joint, 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 the accuracy that joint motion is measured.
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, and a joint is held 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.
Adopt technique scheme, compared with current existing joint angles protractor, the invention has the beneficial effects as follows: before this device revolves for forearm, 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, this device can carry out the measurement turned up in 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 the present invention 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
Below in conjunction with drawings and Examples, the present invention will be further described.
Following example are used for illustrating the present invention, but can not be used for limiting the scope of the invention. Condition in embodiment can do further adjustment according to actual conditions, and unaccounted condition is the condition in normal experiment.
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 is referring to accompanying drawing 1.
The angular surveying dish 1 of the present embodiment is radius is the 10cm semicircular structure being similar to protractor, 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 before meeting forearm rotation, the measurement requirement of supination. Try to get to the heart of a matter central point 2 place on limit of angular surveying is provided with bearing pin.
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 measures arm 5 with second and parallels, and first measures the perpendicular of plane that arm 4 and the second measurement arm 5 formed and angular surveying dish 1. Measure arm 4 with the first of connecting rod 3 connection during measurement and the second measurement arm 5 is integrally forming, jointly rotate, complete to measure purpose.
The using method of the present invention:
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, for the ease of the distance between operation the first measurement arm 4 and the second measurement arm 5, measure arm 5 with palm grip second and rotate activity.
