Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of joint angles dip stick that is applicable to clinical rehabilitation evaluation and rehabilitation teaching.
Background technology
At present, in clinical rehabilitation and rehabilitation teaching process, for the variation of measuring joint angles all is to use the joint angles protractor, but existing joint angles protractor all comprises fixed arm and transfer arm, when measuring joint angles, generally is after fixed arm is fixed, realize the measurement of angle by promoting transfer arm, and this measurement all is to rely on vision to do reference, and precision is low, measurement error easily occurs.
Summary of the invention
The present invention be directed to the existing low defective of joint angles protractor certainty of measurement, provide a kind of and can improve joint angles accuracy of measurement, joint angles dip stick easy to use.
Realize the foregoing invention purpose by the following technical solutions: a kind of joint angles dip stick, comprise angular surveying arm and linear measure longimetry arm, described angular surveying arm is that an end is the rectangular slab body structure of semi arch, and the position, the center of circle of half nose circle of this angular surveying arm is hinged with rotating shaft and linear measure longimetry arm; Central part on described angular surveying arm and the linear measure longimetry arm, be respectively arranged with length standard line and angle reference line along its length direction; The bottom of linear measure longimetry arm is provided with the length scale, is provided with the angle index of 360 degree on the chi face of half nose circle of angular surveying arm along its circumference.
Adopt technique scheme, compare with present standing crop hornwork, the invention has the beneficial effects as follows: this device is easy to use, and is simple in structure, is convenient to make; Because two coaxial connections of gage beam of dip stick, the convenient rotation can guarantee the accuracy of measuring to greatest extent; Convenient use in community-based rehabilitation, hospital rehabilitation, school's rehabilitation teaching.
As preferred version: rotating shaft is arranged on the middle position at 1/3rd places of linear measure longimetry arm.The angle index that the angle reference line is aimed at is 0 degree.
As preferred version: linear measure longimetry arm and angular surveying arm are transparent material and are made.Scale on linear measure longimetry arm and the angular surveying arm all is arranged on the chi face of the same side.
As preferred version: linear measure longimetry arm and angular surveying arm are metal plate.Be provided with length scale and length standard line on the chi face of linear measure longimetry arm both sides; Be provided with angle index and angle reference line on the chi face of angular surveying arm both sides.
As preferred version: angular surveying arm and linear measure longimetry arm are respectively the plate body structure of length 20cm, width 4.5cm, thickness 1mm.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Among the figure: linear measure longimetry arm 1, length standard line 2, length scale 3, rotating shaft 4, angle index 5, angular surveying arm 6, angle reference line 7.
The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Referring to accompanying drawing 1-2, this novel disclosed this joint angles dip stick comprises angular surveying arm 6 and linear measure longimetry arm 1.Angular surveying arm 6 is that an end is the rectangular slab body structure of semi arch, and the position, the center of circle of its half nose circle is hinged with rotating shaft 4 and linear measure longimetry arm 1, can realize free rotation between the two.Rotating shaft 4 is arranged on the middle position at 1/3rd places of linear measure longimetry arm 1.Central part on angular surveying arm 6 and the linear measure longimetry arm 1, be respectively arranged with length standard line 2 and angle reference line 7 along its length direction, wherein the angle reference line 7 on the angular surveying arm 6 runs through the length direction of whole angular surveying arm.The bottom of linear measure longimetry arm 1 is provided with length scale 3, is provided with the angle index 6 of 360 degree on the chi face of half nose circle of angular surveying arm 6 along its circumference.For being convenient for measuring, the angle index that the angle reference line is aimed at is 0 degree, then does along clockwise direction the angle mark distribution of the 0-180 degree of two symmetries with counter clockwise direction take this graticule as benchmark.
Scheme 1: linear measure longimetry arm 1 and angular surveying arm 6 are transparent material and are made.Scale on linear measure longimetry arm and the angular surveying arm all is arranged on the chi face of the same side.Because it is transparent that gage beam is, any one side of this joint angles dip stick can be measured.
Scheme 2: linear measure longimetry arm and angular surveying arm are metal plate.So, be provided with length scale 3 and length standard line 2 on the chi face of linear measure longimetry arm 1 both sides; Be provided with angle index 5 and angle reference line 7 on the chi face of angular surveying arm 6 both sides, like this, also can realize any planar survey of this joint angles dip stick.
As preferred version: angular surveying arm and linear measure longimetry arm are respectively the plate body structure of length 20cm, width 4.5cm, thickness 1mm.
When reality was used, length standard line and angle reference line by the rotational angle gage beam, made the edge of angular surveying arm to the locating tab assembly thing as line of reference, and the angle index that the length standard line on the linear measure longimetry arm is aimed at is joint angles.
