Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a measuring device for measuring the motor function of a joint at a disabled site, mainly in functional recovery training for physically disabled people.

Conventional technology and problems As this type of measuring instrument, for example,
As shown in Publication No. 47356, a measuring container with a circular scale plate and a pointer that always points upward,
There is one in which the joint shaft is rotatably supported by an indicator plate erected on the receiving frame, and a base plate is fixed to the lower part of the joint shaft which is rotatably locked to the receiving frame.

However, when using the above-mentioned measuring device, both ends of the substrate must be bound to the measurement location using appropriate tape or bands. Therefore, not only was it time-consuming to measure, but it could not be used because it could not be restrained in some measurement areas (measuring lateral bending of the thoracolumbar region, measuring internal and external rotation of the forearm). In addition, when making measurements, the scale can be visually recognized from the front of the circular scale plate, but the scale cannot be seen from above or from the side.

Purpose of the invention This invention solves the above problems.When using the invention, the person with a disability, a doctor, a pine surgeon, or other person measuring the measurement area is lightly attached to the measurement point of the person with a disability and allows the person with a disability to perform bending and stretching exercises. It is an object of the present invention to provide a joint motion function measuring instrument whose scale can be viewed not only from the front but also from above and from the side, and which can easily measure pronation and supination movements of the forearm.

Structure of the Invention The structure of the present invention to achieve the above object includes a substrate having two reference planes whose outer end surfaces of the corner portions are perpendicular to each other, and covering the inner side of the corner portion of the substrate,
A box body consisting of fan-shaped side plates centered near the intersection of the substrates inside the corner portion and an arc circumferential plate connected to the outer peripheral surfaces of these side plates, and having an angle scale on the corner plate surface; and the substrate. A pointer rotatably directed to the fan-shaped center inside the corner via a rotation axis and rotated close to the angle scale on the outer surface of the box body, and a pointer so as to always point upward. , a weight attached to the rotating shaft, permanent magnets having different polarities are attached to both outer end surfaces of the substrate of the measuring device, and a mounting portion formed of a magnetic metal plate;
The measuring device is characterized in that the outside end surface of the measuring device is attracted and held by the magnet on the mounting portion of the T-shaped holder, which has a handle fixedly protruding at right angles from the back surface of the T-shaped holder.

Effects of the invention According to the invention, the angle of movement of a joint can be easily measured instantly by simply attaching the measuring device to the measurement site and having the person with a disability perform bending, stretching, or turning movements. The angle scale is visible from the front, side, and top of the box. Alternatively, the two measuring instruments may be used by aligning their vertical back faces with each other and attracting them with the magnet. Rotational movements of 90 degrees or more can be easily measured, and furthermore, by using the T-shaped holder, pronation and supination movements of the forearm can also be easily measured.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

As shown in FIGS. 1 to 3, the measuring instrument 10 of the present invention has two reference planes, ie, bottom end surfaces 11, whose outer end surfaces of the corner portions are perpendicular to each other.
a and a vertical end surface 11b; a fan-shaped box 13 that covers the inside of the corner of the board; The pointer 17 is provided with a pointer 17, and a weight 18 attached to a rotating shaft 16 of the pointer 17 so that the pointer always points upward.

As shown in FIG. 3, the substrate 11 is provided with a recess 11C on each outer end surface, and permanent magnets 19 having different polarities are mounted in the recess 11C. Further, a dimension scale 11d is engraved on both the front and back surfaces of the substrate 11.

The box body 13 includes fan-shaped left and right side plates 13a, 13a centered on the inside corners of the board 11, and an arc circumferential plate 13b provided along the outer peripheral surfaces of these side plates.
On each of these plate surfaces, there is an angle scale 1 with the vertical direction set at 0 degrees and 90 degrees, and the horizontal direction set at 90 degrees and 180 degrees along the circular arc centered on the sector center.
3C is engraved. A window 13d is provided at the base of the side plate 13a on the front side, and the box body 13 is reinforced by quarter-arc-shaped reinforcing ribs 13e (see FIG. 3) that connect parts far from the corners of the board 11. ing.

A bracket 15 is fixed to a mounting base 14 fixedly installed inside a corner of the substrate 11, and a rotating shaft 16 is rotatably supported by the bracket 15. A base end portion of a pointer 17 is fixed to one end of the rotation shaft 16 (the right end in FIG. 2). The pointer 17 extends in the radial direction of the front side plate 13a, in the width direction of the circumferential plate 13b, and further extends to the vicinity facing the angle scale 13C of the back side plate 13a. Furthermore, a transparent fan-shaped protective cover 12 is fixed to the substrate 11, covering the box body 13 and leaving a gap that allows the movement of the pointer 17, thereby preventing problems such as breakage of the pointer 17. There is.

The measuring instrument 10 having the above structure is used by being held in a T-shaped holder 20 shown in FIG. 4, depending on the manner of use. The T-shaped holder 20 includes a mounting part 21 whose surface is made of a magnetic metal plate, and a handle 22 which is fixed at right angles to the back surface and has a grip at the end.
It consists of. Then, the bottom end surface 11a of the measuring device 10 is attracted to the surface of the mounting portion 21 by the magnet 19 for use. In addition, as shown in FIG. 8, if necessary, the vertical end surfaces 1
1b are attracted to each other by the magnet 9, and their bottom end surfaces 11a are attached to the T-shaped holder 20 by the magnet 1.
9 for adsorption and holding. In addition, substrate 1
1 can also be used with the bottom end surface 11a and the vertical end surface 11b reversed.

Next, regarding the measuring device 10 having the above configuration,
Explain how it is used. To measure the forward bending or backward bending function of the thoracolumbar region, as shown in FIG. The handicapped person is allowed to perform a forward bending exercise while holding the hand, and the moving scale of the pointer 17 from the normal position to the forward bending position is read. In the case of backbending, measurement is carried out by supporting the measuring device 10 on the shoulder or by using the T-shaped holder 20 and attaching the bottom end surface 11a of the substrate 11 parallel to the upper surface of the shoulder. In addition, for measuring lateral bending of the thoracolumbar region shown in Fig. 6, and measuring external rotation and internal rotation of the knee joint shown in Fig. 7, it is necessary to
