Sleep pillow {SOUND SLEEP PILLOW}

The present invention relates to a pillow for a good night's sleep, more specifically, the pillow ergonomically designed to adjust the height and angle of the pillow selectively according to the head shape and weight, cervical spine length and angle, etc. By supporting the user's cervical spine and lower head, and having a double elastic structure, it is possible to ideally control the support of the cervical spine and the distribution of body pressure applied to the head and cervical spine so as to realize a personalized pillow superior to the prior art. It relates to a good night sleep pillow.

There are many different types of pillows that can be worn on your head when you lie down to sleep or rest, depending on your age, type of use, and location. When such a pillow makes the sleeping person's posture unnatural, neck or shoulder or waist is loosened, and it is known that neck disk, lumbar disk and the like can develop. If the cushion material of the pillow is too hard, the head of the cervical spine is under pressure so that the blood circulation in the cervical spine is not smooth and the head is bruised even after sleeping due to the lack of oxygen supply to the brain. It is known that there is a risk of cerebral hemorrhage or stroke.

In light of this, Veilleux et al., Canada, US Pat. 6,327,725 through "Pillow with adjustable neck support," US Ganoe et al. 6,951,038 "Adjustable pillow for the proper alignment of the head, neck, and spine" wraps the airbag with a cushion material such as a sponge and proposes a pillow equipped with an airbag consisting of an air injection hose connecting the airbag and the air pump. have.

However, such pillows have a problem in that the distribution of body pressure on each part of the body applied to the pillow and the position of the person lying directly or sideways, that is, the height from the floor to the head and cervical spine (neck) area are not considered.

In order to improve this, Tae GU Kang et al. Of the Republic of Korea proposed a pillow for adjusting the height by installing a pad at the bottom of the cushioning material through US Publication No. US 2005/0177944 "Pillow". This technology allows the pillow users to select a pillow with a more accurate height for their physical characteristics, as the height of the pillow can be adjusted more accurately and easily based on the height of the seat in consideration of the shape of the head of the human body. Expect to be able to sleep comfortably.

However, such a conventional technique is a method of uniformly adjusting the height of the pillow, there is a problem that can not selectively adjust the height and angle of the pillow according to the head shape and weight, cervical spine length and angle, etc., which are different for each individual. . That is, since every person has different head shapes and weights, cervical spine lengths and angles, and different sleeping habits, pillows should be provided to fit an individual's body shape or habits, but the prior arts substantially satisfy these functions. It cannot be done.

Therefore, the present invention has been proposed to solve the problems of the prior art, ergonomically to selectively adjust the height and angle of the pillow according to the head shape and weight, cervical spine length and angle, etc. By design, it is an object of the present invention to provide a new type of sleep pillow that can realize a personalized pillow that is better than the prior art.

A pillow and B pillow is a structure showing the side shape of a conventional conventional functional pillow shape, C pillow is a structure showing the side shape of the cervical spine angle adjustment pad inserted in the lower part of the pillow according to the present invention.

2. Evaluation of the pillow

The experiments in the items below are based on experiments conducted at the Department of Industrial Management Engineering at Dong-Eui University.

end. Evaluation of Necessity of Adjusting Cervical Vertebra when Using Pillow

Inserting the cervical spine angle control pad in the lower part of the pillow using the C pillow according to the present invention, and using the EMG measuring device (ME6000, MegaWin, Finland) to test the EMG according to the change of the neck cervical spine angle is shown in the table below It is the same as the content of 1, which is shown graphically in FIG.

When a person sleeps on a pillow and does not put a burden on the cervical spine, it is possible to get a good night's sleep. The lower the EMG value measured by the present experiment, the lower the burden on the cervical spine. The measurement results in Table 1 below show a significant difference between pillows in the 95% confidence interval.

                                                              (EMG: EMG) time Measuring muscle Cervical spine angle -2 ° 0 ° + 2 ° Early Neck 11.63 ± 4.20 8.96 ± 2.47 7.43 ± 1.92 Neck muscle 6.10 ± 1.77 4.26 ± 1.08 4.87 ± 1.16 After 30 minutes Neck 10.98 ± 4.27 6.84 ± 1.05 8.29 ± 1.43 Neck muscle 6.65 ± 2.24 4.36 ± 1.07 4.59 ± 0.98

According to the contents of Table 1, after 30 minutes in the cervical muscle, the lowest muscle fatigue was observed at cervical spine angle at 0 °, and when the cervical spine angle was + 2 °, the muscle fatigue was increased. At all time points, the lowest muscle fatigue was observed at 0 ° cervical angle.

For reference, when the contents of Table 1 are shown in a graph, the contents of the graph illustrated in FIG. 14 are the same.

For reference, Figure 14 (a) is a graph showing the measured electromyography of the neck and neck muscles immediately lying in the state lying directly on the pillow, Figure 14 (b) is a neck muscles after 30 minutes in the state lying directly on the pillow This is a graph showing the EMG of the neck and extensor.

According to the graph of FIG. 14A, as the neck cervical spine angle is bent in the + direction while the pillow is just starting to cut, the EMG value of the cervical muscles decreases, and the EMG value of the neck muscles decreases and then upwards. According to the graph of FIG. 14B, after 30 minutes, as the neck cervical spine angle is bent in the + direction, the EMG value of the cervical muscle lowers and then upwards, and the EMG of the neck muscle is increased. The value decreases and shows a slight upward increase.

Therefore, it can be seen that the change of the cervical spine angle according to the structure of the pillow and the height of the pillow is very important when the person cuts the pillow and sleeps, as shown in the graphs of Table 1 and FIG. 14.

I. EMG evaluation in the supine position

The results of the EMG experiments in the lying position of A to C pillows are shown in Table 2 below, and the measurement results in Table 2 below show significant differences between pillows in the 95% confidence interval. have.

According to the contents of Table 2, the C-muscle and the extensor muscle was observed the lowest muscle fatigue in the C pillow according to the present invention at all times.

For reference, when the contents of Table 2 are shown in a graph, the contents of the graph illustrated in FIG. 15 are the same.

For reference, Figure 15 (a) is a graph showing the measurement of the EMG of the neck muscles while lying directly on the pillow, Figure 15 (b) is a graph showing the measurement of EMG muscles of the neck muscles lying directly on the pillow. .

All. Evaluation of body pressure measurement at the back of the head

Figure 16 shows the results of measuring the body pressure of the back of the head using a body pressure measuring equipment (CONFORMAT SYSTEM, Tekscan, USA) for A pillow, B pillow and C pillow. In FIG. 16, the portion indicated in blue is in a state of low body pressure, and the portion indicated in red is in a state of high body pressure.

In addition, the neck portion must support a certain amount of body pressure to support the cervical spine, so it is most preferable that the red part appears to some extent on the blue background.

Therefore, in the case of pillow A, the body pressure is almost blue, so the body pressure is low, and the support of the cervical spine is insufficient, and in the case of the pillow B, the body pressure is high due to the high body pressure.
