Abstract
The utility model discloses a move-degree protractor for limb joints, wherein the move-degree of a limb joint is rapidly and accurately measured only by one person.The protractor comprises a protractor scale (1), a fixed arm (2) and a mobile arm (3), which are connected with each other by a rotating shaft (4).The axle center of the rotating shaft (4) is equipped with a balloon sucker (5).A strip band (6) is arranged at a position with a distance from one end of the fixed arm, that accounts for 1/3 of the distance between the end of the fixed arm and the rotating shaft. The rough surface (61) of the band is fixed to the hook face (62) of the outside of the fixed arm.First, the sucker (5) arranged at the axle center of the protractor is fixed to the axle center of a joint to be measured by negative pressure.Then the fixed arm (2) of the protractor is fixed to the limb at one side of the joint to be measured by the strip band (6).The longitudinal axis of the limb at the other side of the movable joint is set to be parallel to and aligned with the mobile arm (3) of the protractor, so that the move-degree of the joint is read.
Description
Technical field: this utility model patent relates to the clinical function evaluation areas, can measure the mobility of limbs 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.There is following problem in the articulation amount hornwork of present clinical use: when measuring the passive joint mobility of paralyzed limbs or stiff limbs, needing two people to cooperate carries 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.The range of motion protractor of this utility model patent design has solved the problems referred to above, only needs a people can measure the passive joint mobility of paralyzed limbs or stiff limbs easily.
This utility model content:
This utility model purpose is to provide a kind of protractor that is convenient for measuring the limbs joint mobility.
The technical scheme of this utility model technical solution problem is:
1. protractor axle center and axle center, measured joint are fixed: improved on clinical protractor commonly used, promptly add a small sucker at the medial surface place in protractor axle center, the skin surface that the axle center can be adsorbed on the axle center, joint by sucker plays fixation.
2. the limbs with protractor fixed arm and joint one side fix: add a rectangular hair side magic tape in protractor fixed arm 1/3 level place far away, the hair side magic tape is walked around the limbs of joint one side, tighten up that the back is pasted with the face that the colludes magic tape of fixed arm lateral surface and, the limbs of fixed arm and joint one side can be fixed.
3. after the position in fixed arm and axle center is determined, when the evaluator does passive activity can for very easily the trouble limb, the turned position of control transfer arm, the mobility in measurement joint.
4. designed fixed arm, transfer arm, magic tape can adopt different length and width design in this utility model patent, to satisfy the needs that different parts limbs joint mobility is measured.
The beneficial effects of the utility model:
Use this utility model patent to carry out the limbs joint mobility and measure, have convenient, fast, advantages such as accuracy rate is high, saving manpower.
Description of drawings:
Further specify below in conjunction with accompanying drawing:
Fig. 1 is the front elevation of protractor
Fig. 2 is the horizontal side figure of protractor
1. circular scale (1) is an one with fixed arm (2), and the scale mark of 0-360 degree is arranged on the graduated disc.
2. circular scale (1) links to each other by axle center (4) with transfer arm (3), forms rotating shaft, and there is a balloon sucker (5) at the place, inboard axle center of graduated disc.
3. the center line longitudinal axis of protractor transfer arm (3) has a mark line, can be used as pointer.
4. there is a rectangular band at protractor fixed arm (2) 1/3 level place far away, and its end has hair side magic tape (61) to fit fixing with the face that the colludes magic tape (62) on the transfer arm lateral surface.
The specific embodiment:
With reference to accompanying drawing, how to use the finger-joint protractor in conjunction with actual implementation method explanation.
The operator advises the measured to put posture and position according to the requirement of clinical measurement of range of motion, according to the definite shaft core position of measuring the joint of body surface symbol, the balloon sucker (5) on the protractor axle center is fixed on joint shaft in the heart by negative pressure.Then with fixed arm (2) longitudinal axis of protractor and the limbs longitudinal axis alignment of measured joint one side.Band (6) on the fixed arm (2) is walked around limbs, hair side magic tape (61) is fitted on the face that the colludes magic tape (62) in fixed arm (2) outside after tightening.The limbs of passive activity joint opposite side with protractor transfer arm (3) longitudinal axis and limbs longitudinal axis alignment, read the number of degrees of joint motion afterwards.
Claims (3)
1. the protractor of a limbs joint mobility, it is characterized in that protractor graduated disc (1), fixed arm (2), transfer arm (3) link to each other by rotating shaft (4), in rotating shaft (4) axle center one balloon sucker (5) is arranged, fixed arm 1/3 level far away has a rectangular band (6).
2. limbs joint mobility protractor according to claim 1, its protractor graduated disc (1) is an one with fixed arm (2), the center of circle of protractor graduated disc (1) is rotating shaft (4) place, axle center, link to each other by rotating shaft (4) with transfer arm (3), rotating shaft (4) medial surface is equipped with a balloon sucker (5), and the hair side of band (61) can be fixing with the face that colludes (62) of fixed arm lateral surface.
3. limbs joint mobility protractor according to claim 1, the fixed arm of design (2), transfer arm (3), band (6) can adopt different length and width design, to satisfy the needs that different parts limbs joint mobility is measured.
