Description

[Detailed Description of the Invention] The present invention relates to a spinal scoliosis measuring device that can measure the degree to which a person's spinal column is curved or twisted laterally.

In recent years, it is said that the rate of discoveries of scoliosis is gradually increasing each time school children are examined for health. What is this scoliosis?
When a person's body is viewed from the front and back, it is a serious disease in which the spinal column curves sideways, and as the symptoms progress, it becomes twisted.Most cases occur from the latter half of school age to adolescence, and the damage to the human body changes depending on the degree of progression. Various obstacles arise. Therefore, it is strongly desired to detect scoliosis early by taking advantage of the opportunity to take off your clothes, such as during a health checkup at school or when using a pool. Conventionally, when scoliosis is detected during a medical examination, the examinee's clothes are removed and there is a difference in the height of the shoulders, or a difference in the height or prominence of the shoulder blades. In addition to checking whether there is a Check to see if there is a difference in height. If there appears to be a difference in height, scoliosis is strongly suspected. Therefore, if there is a difference in height between the left and right sides of the back, as shown in Figure 9, place a ruler b on the back of the subject a' perpendicular to the spine and measure the height difference between the left and right sides. If the difference is 5 mm or less, there is usually no problem, but if it is 7 mm or more, there is a strong suspicion of scoliosis.
However, with conventional testing methods, such as visual inspection, it is easy to determine that scoliosis is suspected if the deformity is severe and obvious to anyone, but if the deformity is mild, it is up to the examiner to judge. Some patients may not be found to be abnormal, and this may lead to a loss of opportunity for detailed examination and the discovery of scoliosis being overlooked. Also, when measuring the difference in height of the back using a ruler, it is not reliable as all measurements are done manually.
Furthermore, the measurement records were manually recorded by the examiner himself, which required a great deal of effort and effort on the part of the examiner. It was difficult to do it accurately.

The present invention eliminates the above-mentioned drawbacks and enables quick and reliable measurement of the lateral curvature of the spine, and when recording the measurement results, it has a simple structure that allows drawing and recording with one motion, making it easy to handle and operate.

Reference numeral 30 denotes an analog spirit level mounted on the upper surface of the frame casing 3 with a pointer 31 directed toward the front of the main body 1, and 32 a handle protruding from the side wall of the frame casing 3.

Next, to explain the movements, first, examinee a
Have them slowly bow with their palms together and their arms hanging naturally in front of them.After this,
The examiner holds the handle 32 and lowers the main body 1 of the proposed measuring device onto the back of the subject a. At this time, the examiner lowers the main body 1 onto the subject's back with the level 30 facing forward, keeping it horizontal while looking at the pointer 31 of the level 30 as shown in FIG. The lower end of a plurality of measurement rods 6 arranged in a comb shape is brought into contact with the most significant portion of the back height difference. As a result, each of the plurality of measurement rods 6 changes its protrusion length one by one depending on the unevenness of the back surface of the subject a, that is, as shown in FIG. When viewed as a whole, the head _6a moves upward in a substantially wave-like manner. After the measurement, the main body 1 of the measuring device is gently removed from the back of the subject a. In this case, each measuring rod 6 has a braking force exerted by the elastic force of the braking plate 13 in the bottom casing 2, so Even when the measuring rod 1 is removed from the back of the subject a, the head 6 a of the measuring rod 6 _does not fall due to its own weight.
maintains the shape of the back of subject a. Therefore, the examiner measures the height difference between the left and right sides of the back of the subject a by reading the position of the head 6 _a of each measuring rod 6 using the scale 19 of the scale plate 15 . Then, based on this measurement result, the examiner determines whether scoliosis is suspected.

Next, to explain the case of recording the measurement results, as described above, each measuring rod 6 is connected to the brake plate 13.
Since the measured state is maintained by the braking action, the recording paper 27 on which the scale 28 is written is
As shown by the two-dot chain line in the figure, insert the recording paper into the frame casing 3 through the recording paper insertion hole 26 on the top surface of the frame casing 3, and then press the operating knob 20 onto the recording paper 27 side with a spring as shown in FIG. 25, and press the pressing plate 24 against the countersunk head _6c of the measuring rod 6 by the support arm 22.
In this state, when the operation knob 20 is moved from one side of the frame casing 3 to the other along the guide rails 14, 14, the pressing plate 24 and the slide plate 20
is moved together with the operating knob 20 by the support arm 22, and as a result, the countersunk head _6c of the measuring rod 6 is moved by the pressing plate 24 at each position on the recording paper 27 where the countersunk head 6c of the measuring rod 6 exists. 6 It will be pressed against _c . Therefore,
As shown in FIG _.
Accordingly, the curved state of the back of the human body in the direction orthogonal to the spine can be recorded as a dotted line.

Next, when the measurement of the subject is finished, or when the measuring rod 6 is returned to the original position to measure the next subject after recording the measurement results on the recording paper 27, first, When the reset rod 11 is pushed downward with a finger, the push plate 9 to which the reset rod 11 is screwed moves downward along the support rod 7 against the force of the compression spring 10 and countersunk the measuring rod 6. _6c and push down the measuring rod 6 until the lower end of the large diameter of the head _6a comes into contact with the upper surface of the bottom casing 2, as shown in FIG. As a result, the measurement rods 6 are rearranged so that they are all at the same height, as shown in FIG. 1, in preparation for the measurement of the next subject. After aligning the measurement rods 6, release the reset rod 11 and the compression spring 1
With zero force, the pressing plate 9 is pushed up to the upper surface inside the frame casing 3 and is ready for the next reset.

As explained above, in this invention, measuring rods with dish-shaped heads are attached to a main body formed in the shape of a horizontally long housing so that they can be moved vertically in a line horizontally. A braking plate is compressed and inserted into the space between the measuring rod and the main body to prevent the measuring rod from falling under its own weight, and on the rear side of the measuring rod head,
A pair of guide rails are arranged at the upper and lower parts of the main body, and a press plate and a slide plate are slid along the guide rails with a scale plate interposed between these guide rails. In addition, above the measuring rod in the main body, there is a pushing plate that moves up and down to push the measuring rod that has been moved upward during measurement downward and return it to its original position. Furthermore, a pressure-sensitive recording paper with a scale written on it can be freely put in and taken out between the measuring stick and the holding plate in the main body, and it can be pressed against the head of the measuring stick by the holding plate. When inserted and measured, when the measuring sticks are pressed against the part of the subject's back where the difference in dorsal height is most significant, each measuring stick moves upward according to the shape of the back. The range is visually measured using the scale plate, and the measuring rod that has moved upward is restrained from falling due to its own weight by a braking member.In this state, a recording paper made of pressure-sensitive paper is inserted into the main body, and the holding plate is placed on the measuring rod. Quickly measure the upward movement range of each measuring rod, that is, the curved state of the back of the human body, on the recording paper by sliding it while pressing it toward the countersunk side of the head.
In addition, since it is configured to enable accurate recording, it has the following effects.

When measuring the scoliosis condition of the spine, this invention
By pressing the main body of the measuring device held in the hand against the subject's back, each measuring rod moves upward according to the curved shape of the back, and by observing the upward movement of the measuring stick, it is possible to measure the spinal column. In addition to being able to determine the degree of curvature, even if the measuring device is removed from the back in this state, the measuring rod is configured so that it will not fall due to its own weight due to the braking member, so the upward movement range of each measuring rod is limited by the braking. Since the measuring rod is held securely by the member, the upward movement range of the measuring rod can be accurately read by the scale plate, and the degree of curvature of the back can be reliably measured. Moreover, by pressing the holding plate downward after measurement, all the measuring rods moved upward,
Because it can be lowered in one motion against the braking force of the braking member and returned to the measurement starting state,
To perform scoliosis inspection work quickly, accurately, and efficiently without requiring special techniques or operations.

In addition, in the present invention, as described above, when the curvature condition of the spinal column is measured with the measuring rod, the measuring rod is held by the braking member so that it does not fall automatically, so this can be easily read using the scale plate. In addition, after measurement, a pressure-sensitive recording paper is inserted into the main body of the measuring device between the measuring stick that has moved upward and the holding plate, and this holding plate is moved to the measuring stick side by the operation knob. By moving the measuring rod along the guide rail while pressing it, the position of the countersunk head of the measuring rod can be drawn and recorded in a dotted line shape on the pressure-sensitive recording paper by the action of the pressure-sensitive paper. That is, the curvature condition of the spinal column can be recorded by drawing the upward movement range of the measuring rod in the form of a dotted line. As a result, the measuring device of the present invention can measure and record the scoliosis condition of the spinal column almost simultaneously, and can perform the scoliosis inspection and recording work of the spinal column efficiently, quickly, and reliably.

Furthermore, in the present invention, the measuring rod has the advantage of being able to accurately hold the measurement results due to the action of the braking member, and when preparing for the next measurement, the pushing plate attached to the main body is pushed downward. It can be quickly and easily restored to its original state. Moreover, the measuring device of the present invention includes a plurality of measuring rods, a braking member that applies braking force to the measuring rods, a scale plate that measures the upward movement range of the measuring rods, and a recording paper for recording the measurement results. It is constructed by incorporating into the main body a pressing plate that moves along the measuring rods arranged in a line while pressing against the countersunk side of the measuring rods, so the structure can be simplified and the structure is small and lightweight. It can be produced economically and is conveniently portable.

In this way, the measuring device of the present invention has a simple configuration and is easy to carry, so it can be used anywhere.
Scoliosis examination and its recording work can be performed quickly, easily, and accurately.
