Abstract
A joint rotation angle protractor comprises a protractor, a base and a strap. A circular dial is embedded into a shell of the protractor, a knob rod is welded on the circle center of the circular dial, a pointer is suspended on the knob rod, and the position of a zero-degree graduation line on the circular dial can be adjusted by rotating a knob. The protractor is connected with the base by a hinge and can be turned outwards by 90 degrees, and the base is connected with the strap by a rotation shaft and can be rotated to different directions. The strap is used for fixing the joint rotation angle protractor to a limb to be measured. In operation of the joint rotation angle protractor, the limb is placed at a middle upright position, the protractor is turned outwards, the base is rotated for adjustment until a plane of the circular angle dial is perpendicular to the rotation shaft, the zero-degree graduation line of the circular dial is adjusted to coincide with the pointer by the aid of the knob, then a joint is rotated, and the degree of the rotation of the joint is obtained by reading an angle graduation value pointed by the pointer. The joint rotation angle protractor can be operated by one person, and rotation mobility of the joint can be rapidly and accurately measured.
Description
Technical field: this utility model patent relates to the clinical function evaluation areas, measures the mobility in rotatable joint.
Background technology: accurately and efficiently measure the range of activity of limbs joint, the clinical reliable functioning appreciation information that provides can be provided.At present clinical measure the joint with the vertical axis be the axle center when making rotary moveable the joint motion number of degrees have following problem: 1. be difficult for determining the position of fixed arm (that is neutral position) when using protractor commonly used to measure, cause operating difficulties, measuring result error bigger.2. when measuring the passive joint mobility of paralyzed limbs or stiff limbs, need two people to cooperate and carry out, promptly a people is responsible for putting the position in joint, and another people's use amount hornwork is measured the angle in joint, operating difficulties.3. measure the anglec of rotation in different joints and need operate at different space planes usually, require the protractor of design can satisfy above-mentioned needs.The joint anglec of rotation protractor of this utility model patent design has solved the problems referred to above, only needs a people can measure paralyzed limbs or stiff limbs joint easily at the planar rotary moveable degree of different spaces.
This utility model content:
This utility model purpose is to provide a kind of protractor that is convenient for measuring the joint anglec of rotation.
The technical scheme of this utility model technical solution problem is:
1. circular angle dial (5) is embedded in dial type protractor (2) shell, knob (3) is welded in the center of circle of circular angle dial (5), pointer (4) hangs on the knob (3), under the action of gravity, pointer (4) all the time dropped finger to the earth's core, circular transparency cover (1) covers the outside at circular angle dial (5) and pointer (4), rotary knob rod passes the center of circle of circular transparency cover (1), knob (3) exposes, the position at the last 0 scale place of the circular angle dial (5) of the rotation scalable by knob (3).
2. the scale on the circular angle dial (5) is two-way to be 0 ° to 180 ° labelling, conveniently reads the angular surveying numerical value of two different directions in same plane.
3. the fixed arm position is definite: protractor is fixed on the measured limbs by band (10), measured limbs are placed on neutral position, overlap the visual arm that fixes of 0 ° of graduation mark of this moment with pointer (4) by 0 ° of graduation mark on the knob adjustment amount hornwork graduated disc.
4. the measurement of the anglec of rotation: measured limbs rotation, the pointer of protractor (4) is owing to the gravity reason is sagging, along with the rotation that respective angles takes place, pointer (4) can be considered transfer arm, and pointer this moment (4) is the number of degrees that measured limbs rotate with the angle number of degrees of the last 0 ° of graduation mark of circular angle dial (5).
5. adjustment amount hornwork surface is to corresponding measurement plane: required amount hornwork measurement plane is vertical with rotating shaft when measuring the anglec of rotation in joint.Protractor shell (2) links to each other with base (8) by hinge (7), can outwards turn over to turn 90 degrees; Can rotate to arbitrarily angled by rotating shaft (9) between base (8) and the band (10).It is vertical with rotating shaft to adjust the protractor measurement plane by said structure.
6. protractor is measured by any part that band (10) is fixed on limbs.
The beneficial effects of the utility model:
Use this utility model patent to carry out the measurement of the joint anglec of rotation, have convenient, fast, advantages such as accuracy rate is high, favorable repeatability, saving manpower.
