Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the following embodiments.
As shown in fig. 1, 2, and 3, the present invention includes a measuring apparatus body including a horizontal angle measuring mechanism 1 for measuring a horizontal rotation angle (rotation angle around Z axis), a left-right angle measuring mechanism 2 for measuring a left-right direction inclination angle (rotation angle around Y axis), and a front-back angle measuring mechanism 3 for measuring a front-back direction inclination angle (rotation angle around X axis).
Specifically, the horizontal angle measuring mechanism 1 is an electronic compass, and the left and right angle measuring mechanisms 2 and the front and rear angle measuring mechanisms 3 are inclinometers. The electronic compass can be divided into a planar electronic compass and a three-dimensional electronic compass. A planar electronic compass requires the user to keep the compass level during use, or else when tilting occurs, it gives a change in angle and virtually no change about the Z-axis. The three-dimensional electronic compass overcomes the strict limitation of a planar electronic compass in use, because the three-dimensional electronic compass is added with the tilt sensor inside, if the electronic compass tilts, tilt compensation can be carried out, and even if the electronic compass tilts, the data of the rotation angle around the Z axis is still accurate. Sometimes temperature compensation may also be built in to overcome temperature drift, minimizing temperature drift of tilt and pointing angles. Therefore, a three-dimensional electronic compass is preferably selected in the utility model.
Since the three-dimensional electronic compass and the inclinometer are the prior art, the structure of the electronic compass and the inclinometer is not described in detail in the utility model.
The horizontal angle measuring mechanism 1, the left and right angle measuring mechanisms 2 and the front and back angle measuring mechanisms 3 are fixed on the support 4, so that the left and right angle measuring mechanisms 2 and the front and back angle measuring mechanisms 3 are perpendicular to each other, and the left and right angle measuring mechanisms 2 and the front and back angle measuring mechanisms 3 are perpendicular to the plane of the horizontal angle measuring mechanism 1. The three positions are fixed through the bracket 4, and the three play their own roles respectively.
In addition, the measuring device further comprises a wearing part used for fixing the measuring device body on the limb of the patient, and the wearing part is connected with the support 4 through threads, so that the measuring device is convenient to detach. The wearing part comprises an annular head band 6 and two arc-shaped fixing bands 7 which are arranged in a crossed mode, and two ends of each arc-shaped fixing band 7 are connected with the annular head band 6; and a mounting seat 5 used for being connected with the support 4 is arranged at the intersection of the two arc-shaped fixing bands 7. The head belt 6 and the two arc-shaped fixing belts 7 are both provided with a retractable buckle 8 for retracting and releasing the length. The head band and the fixing band can be made of plastic sheets, have certain rigidity and certain elasticity, and the retractable buckle 8 can be connected with one pin hole by a pin shaft in a mode of adopting a plurality of pin holes to achieve the retractable purpose.
When using, utilize and dress the part and fix the measuring device body at patient's top of the head to be located same straight line with the cervical vertebra, when the place ahead when patient's eyes are flat simultaneously, control angle measurement mechanism, front and back angle measurement mechanism's reading and be 0, be initial position this moment, and note the angle that horizontal angle measurement mechanism shows. Then, the cervical vertebra of the patient is prompted to rotate according to the training purpose, and the three-dimensional rotation condition of the cervical vertebra of the patient can be visually seen through the readings of the three angle measuring mechanisms.
The above are only preferred embodiments of the present invention, and it should be noted that the above preferred embodiments should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the utility model, and these modifications and adaptations should be considered within the scope of the utility model.
