Description

Head and neck posture adjustment measurement device

The present invention relates to a head and neck posture adjustment measurement device.

It has been found that it is important to take a meal posture that is difficult to cause aspiration as a method for preventing a person with dysphagia from causing aspiration.
However, how can I find a meal posture that is difficult to cause aspiration, and how to easily reproduce the posture that is difficult to cause aspiration on a bed or the like? Or how to make a pillow that can easily take a posture that makes it difficult to cause aspiration without directly contacting a person with dysphagia and obtaining data, etc. At present, no effective concept has been established.
For example, a swallowing contrast test (VF test) is performed for people with dysphagia. In this VF test, the swallowing status of a person with dysphagia is observed with an X-ray or the like to check whether or not the patient can safely swallow. Therefore, it is possible for the patient to know a posture that is difficult to aspirate by taking various postures.
However, in order to accurately reproduce the posture shown in the photographed X-ray photograph, the X-ray apparatus is necessary again.
Further, even if a posture that is difficult to aspirate determined by the VF test is stored as a normal optical photograph, the photograph is necessary for the posture reproduction.
Otherwise, the meal posture is reproduced based on the experience of the meal caregiver. However, this also always requires the same dietary caregiver.
Of course, the gait angle of the bed and the like can be easily obtained as data regarding a posture in which it is difficult to swallow during VF examination. However, further information about the patient's head and neck posture remained almost qualitative.
Therefore, conventionally, even if a posture suitable for preventing aspiration is found, quantitative data capable of accurately reproducing the posture cannot be constructed in the medical field, and posture reproduction is accurately and stably performed. Could not be done.

The spring mechanism 50 provides an action for lowering the pillow body mounting plate 20 levitated by the levitating mechanism 40 downward. The spring mechanism 50 works to stabilize the floating position of the pillow body mounting plate 20 that is levitated, and lowers the pillow body mounting plate 20 downward by deflating the expansion and contraction bodies 41a and 41b. When returning, it is possible to quickly return downward.
Each of the pair of

spring mechanisms

50, 50 is formed by connecting four springs 51 in an X shape, and both lower ends of the X shape are coupled to the upper surface of the apparatus base plate 10 and both upper ends of the X shape are connected to each other. Each is configured to be coupled to the lower surface of the pillow body mounting plate 20.

The said pillow body mounting board 20 is a board for arrange | positioning the pillow body 30 on it, and is made into the flat plate.
The ascending (floating) and descending (sinking) of the pillow body mounting plate 20 is guided from both sides by a pair of

side walls

60, 60.
The pair of

side walls

60, 60 are configured to stand on the upper surface of the apparatus base plate 10. A first guide rail 61 is fixedly arranged in the vertical direction along the inner wall surface of the rear end portion at the rear end portion of the pair of

parallel side walls

42a and 42b, the two expansion / contraction bodies 41a and 41b are expanded, and the rear expansion / contraction body 41b is expanded more than the front expansion / contraction body 41a, The pillow body mounting plate 20 can be floated at a predetermined flying height hf and a predetermined flying angle θf.
And if the pillow body mounting plate 20 is levitated, the 1st slider 21 of the rear-end part 20b of the pillow body mounting plate 20 will move upward along the 1st guide rail 61 with the floating. Further, along with that, the second slider 22 at the front portion of the pillow body mounting plate 20 moves obliquely rearward along the second guide rail 62 inclined.
By using the knob screw pins 21a and 22a of the pillow body mounting plate 20 and tightening the knob screw pins 21a and 22a to the first guide rail 61 and the second guide rail 62, respectively, the pillow body mounting plate 20 is fixed to the position. Can be held. As a result, the pillow body mounting plate 20 can be fixed in a fixed state at an appropriate predetermined floating position hf and a floating angle θf.

Referring to FIGS. 7 and 8, the flying height hf and the flying angle θf of the pillow body mounting plate 20 are set such that the first floating scale 71 arranged in a standing state at the rear end of the side wall 60, and the pillow body Measurement can be performed by reading the second floating scale 72 arranged on the upper surface of the mounting plate 20.
That is, the height of the knob screw pin 21 a of the first slider 21 at the rear end 20 b of the floated pillow body mounting plate 20 is read from the first floating scale 71, thereby The flying height h2 of the end 20b can be obtained. The first floating scale 71 may be a scale indicating the height from the upper surface F of the bed B (the back surface of the apparatus base plate 10). Of course, it is also possible to use a scale indicating the height from the upper surface of the apparatus base plate 10 as to how to apply the scale. In this case, it is necessary to consider the thickness of the apparatus base plate 10 in later calculations.
On the other hand, the floating height h1 of the front end portion 20a of the pillow body mounting plate 20 can be obtained by reading the scale of the second floating scale 72 of the pillow body mounting plate 20 that has floated.

The measurement of the flying height h1 using the second flying scale 72 will be further described with reference to FIGS. 3, 6, 8 to 10, 12, and 13. FIG. A floating position indicator 73 is fixed to the feeding wire 74 along the second floating scale 72. The delivery wire 74 is fixedly attached to the upper surface near the front end of the apparatus base plate 10 and the pillow wire is placed via a pulley 75 provided in the opening 20c of the pillow body placement plate 20. While standing up above the opening 20 c of the plate 20, it extends horizontally above the second floating scale 72 in accordance with the direction of the scale and is connected to the constant load spring portion 76.
In the state where the tip of the pillow body mounting plate 20 is in contact with the apparatus base plate 10, the scale is configured such that the floating position indicator 73 indicates the base value of the second floating scale 72. Here, the base value is specifically a numerical value corresponding to the thickness of the apparatus base plate 10.
When the front end portion 20a of the pillow body mounting plate 20 floats from the apparatus base plate 10, the feeding wire 74 is fed out against the constant load spring 76 by the amount lifted (in the left direction in FIG. 10). Accordingly, the floating position indicator 73 is also moved together with the feeding wire 74 by the amount of floating of the pillow body mounting plate 20 (moved leftward in FIG. 10). Therefore, the flying height h1 of the front end portion 20a of the pillow body mounting plate 20 can be measured by reading the numerical value of the second floating scale 72 indicated by the flying position indicator 73.

In addition, the measurement of the flying heights h1 and h2 of the front end portion 20a and the rear end portion 20b of the pillow body mounting plate 20 is not limited to the specific configuration described above. Of course, other configurations may be used as long as the flying heights h1 and h2 of the front end portion 20a and the rear end portion 20b of the plate 20 can be measured.
Further, the measurement of the flying heights h1 and h2 of the front end portion 20a and the rear end portion 20b of the pillow body mounting plate 20 is performed by indicating the floating position of the knob screw pin 21a of the first slider 21 and the feeding wire 74 as described above. In addition to the reading of the numerical value indicated by the child 73 from the first and second floating

scales

71 and 72, it is also possible to provide means for automatically reading the flying heights h1 and h2.

The flying height hf of the pillow body mounting plate 20 can be represented by the flying heights h1 and h2 at both ends 20a and 20b, and can be represented by the flying height h1 at the front end 20a. Of course, it can be represented by the flying height h2 of the rear end 20b or the flying height (h1 + h2) / 2 at the center in the length L direction of the pillow body mounting plate 20.
Of course, the flying heights h1 and h2 are not necessarily the heights at the both end portions 20a and 20b of the pillow body mounting plate 20, but the flying heights at two predetermined locations of the front and rear portions. h1 and h2.

From the flying height h1 of the front end portion 20a of the pillow body mounting plate 20 and the flying height h2 of the rear end portion 20b, the flying angle θf of the pillow body mounting plate 20 can be obtained by the following equation.
tan θf = (h2−h1) / L
Here, L is the distance from the front end 20a to the rear end 20b of the pillow body mounting plate 20, that is, the length of the pillow body mounting plate 20.

As the pillow body mounting plate 20 rises, the pillow body 30 placed on the upper surface of the pillow body mounting plate 20 rises.
Of course, the flying height Hf of the pillow body 30 can be obtained as a value obtained by adding the thickness of the pillow body 30 to the flying height hf of the pillow body mounting plate 20. In this case, if the scale in the form which added the numerical value which should be added beforehand, such as the thickness of the pillow body 30, is attached to each of the 1st floating scale 71 and the 2nd floating scale 72, by reading hf, It can also be said that the value of Hf has been read.
Of course, the flying height Hf of the pillow body 30 may be represented by the flying height hf of the pillow body mounting plate 20 on which the pillow body 30 is placed.
Further, the flying height Hf of the pillow body 30 is the flying height h1 of the front end portion 20a of the pillow body mounting plate 20, or the flying height h2 of the rear end portion 20b, or the floating height h2 at the center of the pillow body mounting plate 20. The flying height Hf of the pillow body 30 can also be set to the height (h1 + h2) / 2.
Since the floating angle of the pillow body 30 is the same as the floating angle θf of the pillow body mounting plate 20, it can be represented by θf.

The first slider 21, knob screw pin 21 a, second slider 22, knob screw pin 22 a, first floating scale 71, second floating scale 72, floating position indicator 73, feeding wire 74, pulley 75, constant load spring 76 Constitutes a floating position measuring means M2.
The knob screw pin 21a, the first floating scale 71, the second floating scale 72, and the floating position indicator 73 constitute a means for reading the height of the pillow body 30 from the upper surface F of the bed B.

4 and 5, the pillow body 30 includes a base portion 31 and a rotating portion 32 combined on the upper surface thereof.
As will be described later, the base portion 31 is slidably disposed on the pillow body mounting plate 20.
On the upper surface of the base portion 31, an arc-shaped receiving groove 31a having a cross-section of an arc-shaped concave groove is provided in the longitudinal direction (see FIGS. 2, 5, 6, and 9). The arc-shaped receiving bottom 31a is combined with the arc-shaped back bottom 32a of the rotating portion 32. The arc-shaped back bottom portion 32a is configured such that the cross section bulges in an arc shape. As a result, the turning part 32 is held from below by the base part 31 and can be freely turned around the longitudinal direction of the pillow body 30 (the axial direction of the head and neck).
The upper surface of the rotating part 32 is a slanted surface that ascends with a constant slope from the front end side to the rear end side in the longitudinal direction as a whole. In addition, a head and neck rest recess 32b is provided at the center of the upper surface so that the head and neck of the person P to be measured who is in a supine posture is placed stably.

That is, when the operation button 85c of the magnet type attaching / detaching button 85 is pressed slightly strongly, the magnet portion 85b is detached from the magnet fixing mounting bracket 84 and is attracted to the lower magnet fixing iron plate 83. Further, when the operation button 85c of the magnet type attaching / detaching button 85 is slightly pulled up, the magnet portion 85b is detached from the magnet fixing iron plate 83 and is attracted to the magnet fixing mounting bracket 84.
While the magnet portion 85b is attracted to the magnet fixing mounting bracket 84 side, the base portion 31 of the pillow body 30 can freely slide. On the other hand, when the magnet portion 85b is attracted to the magnet fixing iron plate 83, free sliding movement of the base portion 31 is prohibited at that position, and the base portion 31 is held at that position.
Therefore, when the final position of the head and neck of the person to be measured P is determined, the slide position ps of the base 31 of the pillow body 30 can be fixed.
However, in the present invention, by providing the magnet fixing bracket 84 with the elongated hole 84a, the movement of the pin rod 85a penetrating the elongated hole 84a in the sliding direction is provided with play. Due to this play, the base portion 31 of the pillow body 30 can be adjusted in a small amount within the range of the elongated hole 84a even in a state where free sliding movement is prohibited. As a result, even after the slide position ps of the base part 31 is substantially determined, the base part 31 can be slightly slid according to the slight movement of the head and neck of the person P to be measured. The load is not applied to the person P.

8 and 9, the means for measuring the relative slide position ps of the base 31 of the pillow body 30 with respect to the pillow body mounting plate 20, that is, the pillow body slide position measuring means M6 is the pillow body. A second floating scale 72 provided on the upper surface of the mounting plate 20 and a slide position indicator 86 attached to the base 31 of the pillow body 30 can be used.

Therefore, the slide position indicator 86 and the second floating scale 72 are means for reading the relative slide position ps of the pillow body 30 with respect to the pillow body mounting plate 20, and this becomes the pillow body slide position measuring means M6.

A method for adjusting and measuring the three-dimensional posture of the head and neck of the person P to be measured will be further described with reference to FIG.
Now, when the grip pumps 42a and 42b are operated in a state where the head and neck of the subject P sleeping on the bed B is placed on the head and neck resting recess 32b of the rotating part 32 of the pillow body 30, the expansion and contraction body 41a 41b swells. At this time, usually, the degree of expansion of the rear expansion / contraction body 41b is larger than the expansion degree of the front expansion / contraction body 41a, so that the flying height h1 of the front end portion 20a of the pillow body mounting plate 20 is later. The flying height h2 of the end 20b is set higher. By doing in this way, the pillow body mounting plate 20 is inclined so as to become higher from the front end portion 20a toward the rear end portion 20b.
The flying height hf of the pillow body mounting plate 20 may be represented by h1 or h2, or may be represented by an average value thereof.
The flying height Hf of the pillow body 30 uses the flying height hf of the pillow body mounting plate 20, and in addition to this, the head and neck resting recess 32b of the rotating portion 32 of the pillow body 30 from the pillow body mounting plate 20 is used. It can be expressed as a value obtained by adding up to the height difference dimension. Further, the flying height hf, that is, the flying height of the lower surface of the base portion 31 of the pillow body 30 is equivalent to the flying height Hf of the pillow body 30 as it is.
On the other hand, the floating angle θf of the pillow body mounting plate 20 can be set as the floating angle of the pillow body 30 as it is. The flying angle θf of the pillow body 30 can be obtained as tan θf = (h2−h1) / L using the h1 and h2 and the length L of the pillow body mounting plate 20.

With reference to FIGS. 8 and 9, the pillow body mounting plate 20 that slides in the longitudinal direction on the pillow body mounting plate 20 as the head and neck of the measurement subject P is displaced in the axial direction of the head and neck portion. The slide position ps can be obtained by reading the second floating scale 72 on the pillow body mounting plate 20 indicated by the slide position indicator 86 of the base portion 31 of the pillow body 30.

Referring to FIG. 5, the rotation of the pillow body 30 is carried out in a state where the arcuate back bottom portion 32 a of the rotation portion 32 of the pillow body 30 is combined with the arc-shaped receiving groove 31 a of the base portion 31. It can be done by turning in the direction.
The rotation angle θk of the pillow body 30 may be obtained by reading the value of the rotation scale 33 of the base portion 31 indicated by the rotation angle indicator 34 when the rotation portion 32 rotates.

In order to find a predetermined three-dimensional posture of the head and neck of the measurement subject P, for example, a posture in which aspiration is difficult to occur, this device and an X-ray machine can be used.
That is, as described above, the head and neck of the person to be measured P is placed on his back on the pillow body 30 of the apparatus placed on the upper surface F of the bed B.
Then, the grip pumps 42a and 42b are operated from this state to adjust the flying height Hf and the flying angle θf while floating the pillow body mounting plate 20, and variously while adjusting the rotation part 32. X-ray imaging of the swallowing part in the head and neck of the subject P in a correct posture is performed to identify the best aspiration prevention posture.
When the aspiration prevention posture is specified, the flying height Hf and the flying angle θf of the pillow body 30 at that time are read, the rotation angle θk is read, and the slide position ps is read.
As described above, the predetermined three-dimensional posture of the head and neck of the measurement subject P can be reproduced at any time with the flying height Hf, the flying angle θf, the rotation angle θk, and the slide position ps of the pillow body 30.

By obtaining the flying height Hf, the flying angle θf, the rotation angle θk, and the slide position ps of the pillow body 30, a dedicated three-dimensional posture of the head and neck part such as the aspiration prevention posture of the measurement subject P can be reproduced. A pillow can be easily produced.
That is, the pillow body 30 including the base portion 31 and the rotating portion 32 as described above is prepared. Then, an adjustment stand placed under the pillow body 30 is separately formed using the flying height hf, the flying angle θf, and the slide position ps obtained for the obtained pillow body mounting plate 20. Then, by fixing the pillow body 30 on the adjustment table, a dedicated pillow capable of reproducing a predetermined three-dimensional posture of the head and neck can be obtained.
