The present invention relates to a pillow for preventing sleep respiratory disorders to prevent the occurrence of respiratory disorders during sleep, and more particularly to obstructive sleep apnea due to repeated closure of the upper airway located in the neck of the human body. ), And a pillow for preventing sleep respiratory disorder that can prevent and treat habitual snoring that occurs in this regard.

The habitual snoring and sleep apnea and upper respiratory tract syndrome, which are generally classified as sleep respiratory disorders, are characterized by repetitive closure of the upper airway during sleep, which reduces night sleep efficiency and prevents deep sleep, especially blood Results in lowering oxygen saturation [Chokroverty S. (1994) Sleep Disorder Medicine. Butterworth-Heinemann]

These sleep respiratory disorders cause daytime drowsiness, decreased concentration, decreased memory, poor learning ability, chronic fatigue, safety accidents in industrial sites and workplaces, and traffic accidents caused by drowsy driving while driving. • It is causing a great loss economically.

In addition, recent studies have shown that these sleep respiratory disorders are closely related to the development of obesity, hypertension, diabetes, dementia, cardiovascular disease, heart attack, sexual decline, cerebrovascular disease, stroke, and metabolic syndrome. [Prospective study of the association between sleep-disordered breathing and hypertension. N Engl Med 2000; 342: 1378-1384.

Sleep respiratory disorders are present in women as well as men worldwide. In the United States, 28% of men (about 75 million) and 16-18% of women (about 48 million) suffer from sleep respiratory distress [The occurrence of sleep-disordered breathing among middle-aged adults. N Engl J Med 1993; 328: 1230-1235.

Recently, Korean studies showed that 27% of men (about 1.2 million) and 16% of women (760,000) suffered from sleep respiratory disorders [Prevalce of sleep-disordered breathing in middle-aged Korean]. men and women. Am J Respir Crit Care Med. 2004; 170 (10): 1108-13], and two to three out of 10 adult populations were exposed to respiratory disorders during sleep.

In Korea, despite the low obesity or abdominal circumference that previous reports indicate as the most dangerous factor of sleep respiratory disorder, the rate of sleep respiratory disorder is similar to that of the United States. The increase in obesity or abdominal circumference caused by eating habits is expected to increase the number of patients with sleep respiratory disorder.

Causes of sleep respiratory disorder include obesity, family history, anatomical abnormalities, sex differences (which occur more often in men than women), and medical diseases (thyroid disease).

Structurally, it is caused by the obstruction of the soft airway of the nasopharynx, oropharynx, and hypopharynx in the upper airway, which is the passage of air inflow and outflow. .

It can be seen that the strength of muscle on the EMG is greatly reduced when sleep begins, and this phenomenon causes not only the relaxation of the soft tissues of the upper airway but also the activity of many respiratory muscles, leading to the obstruction of the airway during sleep [Chokroverty S. ( 1994) Sleep Disorder Medicine. Butterworth-Heinemann].

1 is a diagram illustrating the obstruction of the upper airway that causes sleep respiratory disorder.

In general, the flow rate Q of a fluid is expressed as the product of the cross-sectional area A of the flow path and the velocity v of the fluid as follows.

Q = A

(Q is the flow rate of the fluid, A is the cross-sectional area of the flow path, v is the velocity of the fluid)

The same equation holds for the cross-sectional area of the upper respiratory tract where air flows in and out during sleep, A, the velocity of air, and the flow-in air volume, Q, and when the amount of air Q needed to supply oxygen to the body is constant, As the cross-sectional area decreases, the air velocity v increases, which causes snoring.

Moreover, when soft tissue closes the upper airway, and the cross-sectional area A of the upper airway becomes zero, the amount of inflow and outflow air becomes zero, resulting in sleep apnea.

As shown in FIG. 1 (a), the upper upper respiratory tract 4 has a sufficient upper respiratory tract 4 through which air supplied to the bronchus and lungs (not shown) can be secured, but FIG. In the sleep apnea state, the soft tissue 6 extending from the posterior head side of the palate 8 is caused by the pressure of the soft tissue 6 due to its own weight of the soft tissue 6 and the weight of the tongue 7. It will close the figure (4).

This upper respiratory tract obstruction worsens when lying in the supine stomach during sleep, and when the upper respiratory tract is closed, the sleep apnea becomes difficult or stops during sleep.

Snoring is also a phenomenon that occurs when the upper airway 4 partially closes during sleep.

Various methods have been tried to treat snoring or sleep apnea.

Typically, i) a lifestyle regimen that facilitates air flow to the upper airway by adjusting the sleeping position to change to the lateral or supine position, ii) a surgical therapy to remove the sagging soft tissue 6 of the upper airway (4), Or iii) a continuous positive airway pressure (CPAP) 9 that injects positive pressure from the outside as shown in FIG. Non-surgical therapies are being attempted to open (4) continuously.

However, it is true that these therapies have limitations.

i) There is no guarantee that lifestyle therapy will maintain sleeping posture continuously in the lateral or supine position, ii) Surgical therapy has a high recurrence rate due to soft tissue regeneration, and iii) Non-surgical therapy provides a positive mask during sleep. There is a discomfort to wear, the compliance of the patient (compliance) is reduced.

Therefore, as an alternative treatment, there is an attempt to treat sleep respiratory disorder using a functional pillow during sleep, and a posture correction pillow has been developed such as mainly increasing the position or head position.

However, these functional pillows, which have been developed so far, have not shown any results [Elevated posture for management of obstructive sleep apnea. Sleep and breathing, 2004; 8 (4): 193-200.].

Also recently, a "memory foam", a polymer foam product invented by NASA scientists, is commercially available, which absorbs the loads and shocks transmitted to the body and returns to its original shape when the load is relaxed. Its thin ergonomic pillow does not have a significant effect on snoring or sleep apnea.

This is because these pillows for the treatment of sleep respiratory disorder do not adjust the shape of the pillow according to the change of the upper airway due to the change of position during sleep, and recognize the degree of snoring and sleep apnea and accordingly the function of the pillow accordingly This is because it cannot be adjusted.

In particular, these pillows provide a passive system that is difficult to actively control in terms of frequent changes in sleep position in patients with sleep respiratory distress, and the characteristics of individual head and cervical spine and position change are not considered. And pillows with a level of sleep posture correction rather than a function as a professional medical treatment tool.

Therefore, it is difficult to expect such a great effect in the treatment and alleviation of snoring and sleep apnea with the existing pillows, and in fact, the therapeutic effect to prevent recurrence of sleep respiratory disorder is insignificant.

The present invention was devised to solve the above problems, considering the characteristics of the individual head, cervical spine of the patient, it is possible to form an optimal head, cervical spine pressure distribution can maintain the body's sleeping posture The purpose is to provide a pillow.

Another object of the present invention is to provide a pillow having a sensor capable of detecting snoring during sleep and a sensor capable of detecting a decrease in blood oxygen saturation due to snoring and sleep apnea.

Furthermore, when snoring or sleep apnea is detected automatically, and when snoring or sleep apnea is detected, the neck support (bottom and neck) of the pillow is automatically inflated, raising the pillow user's chin and extending the cervical spine. By reducing the ventilation resistance of the upper airway, providing a pillow to prevent airway obstruction of the head and cervical spine, and also, if the snoring or sleep apnea is determined not to be resolved due to the expansion of the neck support portion of the pillow The purpose is to provide a pillow for changing the side to side.

The artificial intelligence control device prevents the breathing disorder by opening the upper respiratory tract by expanding the part supporting the neck of the human body or changing the sleeping posture of the human body to the side and position so that the jaw of the human body is raised and the cervical spine is extended. It may be configured to output pressure control data for controlling expansion or contraction of each chamber to the pressure regulator.

A storage device 50 for storing control data including an optimum pressure pattern data, a control data being loaded, and a pressure of each chamber 22 is input from the pressure detecting means 40, and the control data and each chamber ( It is determined whether the respiratory disorder has occurred through the comparison of the pressure of 22), and if it is determined that the respiratory disorder has occurred, the pressure control data for controlling the expansion or contraction of each chamber 22 to control the expansion or contraction of the respiratory disorder by opening the upper airway. Artificial Intelligence Output to Device 30 The control device 60 is included.

The pillow body 20 is formed to support the head 2, the lower head 12, and the lower neck 14, as shown in Figure 2 (a) or 3 (a), or Figure 2 (b) or as shown in Fig. 3 (b), it is formed to support the head 2, the lower head 12, the lower neck 14, and the thigh 15, so that the correct sleeping posture of the human body Can be derived.

Preferably, as shown in Figure 3, the pillow body 20 is formed by dividing into a plurality of chambers 22, in this case each chamber 22 is preferably formed so that the left and right are symmetrical.

In FIG. 3 (a), four chambers 22 are formed in the longitudinal direction and three chambers 22 in the transverse direction, thereby forming a total of 12 chambers 22. In FIG. 3 (b), four chambers in the longitudinal direction, four in the transverse direction. Four chambers are formed to form a total of 16 chambers 22, but this is only an example, and of course, various chambers 22 can be arranged.

That is, as shown in Fig. 4 (a) or 4 (b), the upper chamber (22u) that the upper part of the head (2) touches consists of one chamber (22u) longitudinally, and the pillow user The lower chamber 22dr and 22dl which the neck part contacts consists of a lower left chamber 22dl and a lower right chamber 22dr, and are horizontally fixed part 22f between the upper chamber 22u and the lower chamber 22dr and 22dl. ) May be provided.

Of course, another fixing portion 22ff may be provided between the lower left chamber 22dl and the lower right chamber 22dr.

Here, the fixing portions 22f and 22ff are not expanded even when pressure is supplied to each of the chambers 22 and is kept flat.

In addition, as shown in Fig. 4 (c), the upper chamber (22u) that the upper part of the head (2) touches consists of one chamber (22u), the intermediate chamber (22m) is in contact with the lower part of the head of the pillow user It consists of one chamber (22m), it may also be made of a lower chamber (22d) in contact with the lower part of the neck of the pillow user.

Of course, as shown in Fig. 4 (d), between the intermediate chamber 22m and the lower chamber 22d, a fixing portion 22f for lengthening the distance between the intermediate chamber 22m and the lower chamber 22d is provided. It may be provided.

Of course, although not shown in the drawings, the pillow for preventing sleep breathing disorder shown in Figure 4 is formed to extend the separate chamber, to support the thighs (reference number 15 in Figure 2 (b)) of the human body, sleep breathing disorder By expanding the chamber located at one end of the longitudinal section of the prevention pillow may be able to change the sleeping posture of the human body side to side.

In addition, as shown in FIG. 4, the base 21 may be formed under the pillow body 20 in contact with a sheet (not shown) under the pillow body 20. The substrate 21 supports the expansion of the chamber 22 so that the expansion of the chamber 22 is made in the upward direction of the pillow body 20 in contact with the human body, and is made of a material that does not slide well on the seat. 20) is preferably formed to prevent slippage.

As shown in FIG. 5, the pressure regulator 30, which supplies or discharges pressure to each chamber 22 so that each chamber 22 may expand or contract, actively supplies pressure to each chamber 22. Alternatively, the pressure in each chamber 22 is adjusted by discharging.

Pressure control of the pressure regulating device 30 is performed in each chamber 22 unit, thereby enabling active control according to the position of the human body during sleep.

The pressure detecting means 40 which detects the pressure of each chamber 22 detects in real time the pressure of each chamber, grasping which chamber 22 is pressed by the human body, and breathing in the breath of the pillow user. And while grasping the change in the pressure applied to the chamber 22 by the exhalation operation, and at the same time grasping the vibration of the back of the head caused by the sleep breathing disorder.

Memory 50 for storing data is a device for storing the basic data necessary for the control of the sleep respiratory disorder prevention pillow, the state when the pillow user is taking normal sleep in the supine position, that is, in the state that the sleep respiratory disorder does not occur The control data which data-patterned the pattern by which the pressure of each chamber 22 changes is stored.

The artificial intelligence controller 60 which outputs the pressure control data to the pressure regulating device 30 loads the control data from the storage device 50, and each chamber 22 according to the position of the pillow user from the pressure detecting means 40, etc. Receive the pressure of), compare the loaded control data and the input pressure to determine whether the pillow user's breathing disorder occurs, and if it is determined that the breathing disorder has occurred, the pillow user's upper respiratory tract In order to induce the position of the pillow user (4 in FIG. 2) is opened, the pressure control data for outputting or contracting each chamber 22 to the pressure regulator 30 is output.

Here, the pressure control data of the chamber 22 to open the upper airway of the pillow user typically corresponds to the lower head 12 or the lower neck 14 at the supine position, as shown in FIG. The chamber 22 is to be expanded relatively.

Looking at the determination of the occurrence of sleep respiratory disorder by the artificial intelligence controller 60 as follows.

The breathing pattern in the sleep state of the pillow user is shown in FIG. 6.

The vertical axis of the graph of the breathing pattern shown in FIG. 6 is the pressure in the chamber 22 detected by the pressure detecting means 40, and the horizontal axis represents time.

The rising section of the graph is an inhalation section in which the pillow user inhales air through the mouth, and the falling section is an exhalation section in which the pillow user discharges air through the mouth, and the horizontal section is a resting section of inhalation and exhalation.

The pattern of inhalation and exhalation in the normal sleep state is measured for each chamber 22, and data such as a graph representing the pressure pattern of each chamber 22 is stored in the storage device 50.

In this case, since each pillow user has a different characteristic such as a breathing cycle T and a pressure pattern pressed by each chamber 22 according to individual characteristics, data such as a graph indicating the pressure pattern of each chamber 22 is individualized for each pillow user. It is preferable to be.

Whenever the pillow user uses the pillow, the pressure detecting means 40 detects the pressure in each chamber 22 in real time, and the detected data is compared with the pattern of inhalation and exhalation in a normal sleep state.

Looking specifically at the pattern of inhalation and exhalation in the normal sleep state and the data detected from the pressure detecting means 40 when using the pillow, in the normal sleep state, as shown in Figure 6 (a), While the repetitive breathing period T appears almost constant and the vibration waveform appears smooth, while the pillow user snores, as shown in FIG. 6 (b), the respiratory period T of inhalation and exhalation is normal. It is similar to the sleep state, but the vibration waveform is not smooth in the inhalation section or the exhalation section.

Therefore, when the vibration waveform which is not smooth in the inhalation section or the exhalation section appears in comparison with the vibration waveform of the normal sleep state, it is determined that the pillow user snores, and the control for opening the upper airway (4) is started.

In addition, as shown in Fig. 6 (c), when the sleep apnea appears in the pillow user, the rest period is prolonged without repeated breathing cycles of inhalation and exhalation, or the vertices in the inhalation interval is significantly lowered, or Inhalation and exhalation intervals appear irregularly.

In FIG. 6C, the dotted line is a vibration waveform in a normal sleeping state.

Therefore, compared to the normal sleep vibration waveform, when the rest period is prolonged, the peaks in the inhalation section are significantly lowered, or the inhalation and inspiration sections appear irregularly, the pillow user is in a state of insomnia. After the determination, control for opening the upper airway (4) is started.

Here, as shown in Fig. 7 (a), such control is performed by the artificial intelligence controller 60 to the pressure regulator (30 in Fig. 5), the lower part of the head 12 and to open the upper (4) Pressure is applied to the chambers 22m and 22d in contact with the lower head 12 and the lower neck 14 to raise the lower neck 14, and the pressure in the chamber 22u in contact with the upper head is increased. By discharging.

By this control, the upper airway 4 is opened, and snoring and sleep apnea are eliminated.

Even after adjusting the pressure in each of the chambers 22m, 22d, and 22u, the vibration waveform of the pillow user's sleep and the vibration waveform of the normal sleep state are compared, so that the rest period becomes longer or the peak of the inhalation period is significantly lower. Or, if the breathing and exhaling intervals appear irregularly, it is determined that the pillow user is in the state of apnealess apnea, the control to open the upper airway (4) by changing the sleeping posture of the human body to the side and position.

Here, as shown in Figure 7 (b), such control is the artificial intelligence control device 60 to the pressure regulator 30, the lower neck 14 and the thigh 15 to open the upper airway (4) This is achieved by applying pressure to the chambers 22d1 and 22e1 in contact with one side of the lower neck 14 and the thigh 15 so as to raise one side.

By this control, the sleeping posture of the human body is guided to the side and stomach, the upper airway (4) is opened, so that snoring or sleep apnea is eliminated.

The control in the artificial intelligence controller 60 is based on fuzzy control in consideration of the respiratory cycle of the pillow user's use of the pillow, the height of the peak in the inhalation section, or the degree of waveform vibration. desirable.

Fuzzy control is based on a control algorithm designed to overcome the performance limitations of the hardware, and processes the uncertainty on the boundary as an intermediate value and inputs various types of information while simplifying the information from the pressure detecting means 40 as much as possible. By performing the actual control in terms of the human judgment method and calculation method, it is suitable for judging the occurrence of sleep respiratory disorder of the pillow user.

Of course, the sleep breathing prevention pillow according to the present invention, as shown in Figure 5, the power supply for supplying power (not shown), and further includes an operation panel 28 to select the function of the sleep breathing prevention pillow can do.

The power supply supplies electricity to the pressure detecting means 40, the pressure regulating device 30, the memory device 50, and the artificial intelligence control device 60, and may be constituted by an AC power source. It is preferable to be configured to use a battery (not shown) to increase the height and to avoid the trouble and the danger of going to bed.

Herein, the battery may be a fluid battery, and may be battery replaceable or rechargeable.

As shown in Fig. 5, the operation panel 28 is for an interface with a pillow user, and is provided with a key or a button as an input means, so that at least the on-off operation can be selected, and other functions such as a clock can be selected. You may be able to.

Of course, the operation panel 28 may be provided with a display means such as LED or LCD for displaying the operating state of the sleep respiratory disorder preventing pillow according to the present invention.

8, the chamber cell 24 is provided inside the chamber 22, and one chamber cell 24 may include a plurality of air cells 26.

Here, when the pressure is supplied to the pillow body 20, each chamber 22 is a unit, the pressure is supplied therein, the pressure is detected, a plurality of air cells 26 or chamber cells 24 ), One pressure is supplied, and the pressure detection can also be made by one common pressure detecting means 40.

8 (a) is a perspective view of one air cell 26, and FIG. 8 (b) is a perspective view of one chamber cell 24 having a plurality of air cells 26.

The air cell 26 has a cup shape, and includes a plurality of pillars 28 for resilience, resilience, and strength reinforcement.

The number of the pillars 28 can be determined experimentally in consideration of the internal pressure, the degree of expansion and the number of expansion required for the air cell 26. In FIG. 8 (a), for example, the number of the pillars 28 has eight pillars 28. An air cell 26 is shown.

As shown in FIG. 8B, the chamber cell 24 includes a plurality of air cells 26 and is supplied with a common pressure.

The number of air cells 26 included in one chamber cell 24 is determined in consideration of the area and the like occupied by the chamber cell 24. In FIG. 8 (b), 12 air cells 26 are illustrated as an example. The chamber cell 24 is shown.

Here, each air cell 26 may be formed to have a height required at each position according to each position in one chamber cell 24, of course.

9 illustrates an example in which the chamber cell 24 is disposed in the sleep respiratory disorder preventing pillow according to the present invention.

The interior of the chamber cell 24 includes a plurality of air cells 26.

The air cells 26 are connected to each other in a constant shape, so that even if a single pressure is applied to the whole, the air cells 26 expand and contract while maintaining a predetermined shape, thereby maintaining the shape of the pillow body in an intended shape. The pressure in the cell 24 is facilitated to adjust.

In addition, since a plurality of air cells 26 in the chamber cell 24 are sensed and adjusted in pressure, the air cell 26 may be used even when the load of the head in contact with the pillow body is concentrated only on some air cells 26. It is pressed and contracted, but the pressure is transmitted to the other air cells 26 to expand, so that the distribution and adjustment of the load in one chamber cell 24 is made naturally.

On the other hand, the detection of sleep respiratory disorder, but by the pressure detecting means 40, as shown in Figure 5, may be further provided with another device to assist this, for example, the sound sensor 42 or vibration The sensor 44 may be provided and connected to the AI controller 60.

In this case, the memory device 50 should further store the optimum sound pattern data or the optimum vibration change data during normal sleep.

The sound sensor 42 or the vibration sensor 44 detects a sound pattern or a vibration change in real time whenever the pillow user uses the pillow, and the detected data is optimal sound pattern data or optimal vibration change data during normal sleep. Is compared with.

In addition, the blood oxygen saturation detection sensor 46 is further provided may be connected to the artificial intelligence control device (60).

In this case, the optimal blood oxygen saturation data for normal sleep should be further stored in the memory device 50.

Whenever the pillow user uses the pillow, the blood oxygen saturation detection sensor 46 detects the saturation of oxygen in the blood in real time, and the detected data is compared with the optimal blood oxygen saturation data during normal sleep.

Blood oxygen saturation detection sensor 46 is connected to the artificial intelligence control device 60, the artificial intelligence control device 60 loads the optimal blood oxygen saturation data from the memory device 50, blood oxygen saturation detection sensor 46 Blood oxygen saturation data is inputted from the control panel), and a comparison between optimal blood oxygen saturation data and blood oxygen saturation data is performed to determine whether a respiratory disorder occurs.

The artificial intelligence controller 60 determines that a sleep respiratory disorder occurs when the blood oxygen saturation data measured in real time is out of the error range of the optimal blood oxygen saturation data.

The blood oxygen saturation detection sensor 46 is able to assist in determining sleep respiratory disability, and thus, sleep respiration along with determination of respiratory distress by the pressure detecting means 40, the sound sensor 42, and the vibration sensor 44. By determining the disorder, it becomes possible to determine a more accurate sleep respiratory disorder.

By the way, there may be a case that the pillow user takes a sleep while changing the sleeping posture severely at the time of sleep, in which case there is a possibility that the effectiveness of the control of the artificial intelligence controller 60 is lowered.

Therefore, when the pillow user changes the sleeping posture during sleep, it is necessary to monitor the change in the sleeping posture and return the sleeping posture to the supine or lateral position so that the sleeping posture is the supine or lateral position where the sleep breathing disorder does not occur.

To this end, the artificial intelligence control device 60 determines whether the sleeping posture is changed, and if it is determined that it is out of the supine position or the side position, the control is performed to return to the supine position or the side position position.

That is, the artificial intelligence control device 60, when the pillow user is sleeping in the supine position without sleeping breathing disorder, the pressure pattern in each chamber has a constant breathing period (T) on the left and right sides and almost in the inhalation period. When the pillow user is sleeping in the side and stomach position without sleeping breathing disorder, the chamber in contact with the face of the head is pressed by the pillow user's face and detected by high pressure, Based on the relatively low pressure detected, the chamber judges that the sleeping posture of the pillow user has changed when this pressure pattern is changed, and returns the sleeping posture of the pillow user to a state of no supine or lateral sleep breathing disorder. To perform the control.

For example, as shown in FIG. 10 (a), when the pillow user is sleeping in the supine position without sleeping breathing disorder, the pressure pattern in each chamber has a constant respiration cycle (T) at the left and right sides. When the sleeping posture of the pillow user is changed, as shown in FIG. 10 (b), the pressure pattern of the right chamber has a changed pressure pattern that is detected as a high pressure. do.

At this time, the artificial intelligence controller 60 determines that the sleeping posture of the pillow user is changed, and performs the control for returning the pillow user to the supine position.

The control for returning the pillow user to the supine position, as shown in Fig. 10 (c), supplies pressure to the chamber in contact with the face side of the head 2, and the chamber in contact with the back head releases the pressure. By making the pressure between the chambers asymmetrical, the pillow body 20 is inclined to induce rotation of the sleeping posture.

The control of the artificial intelligence control device 60 is the same even when the pillow user takes a sleep to the side and position without the sleep breathing disorder is changed in the pressure pattern by changing the sleeping posture.

That is, although not shown in the drawing, when the pillow user is sleeping in the position of the side and stomach without sleep breathing disorder, the chamber in contact with the face side of the head is pressed by the pillow user's face and detected by high pressure and the chamber in contact with the back head. Is detected at a relatively low pressure, but when the sleeping posture of the pillow user is changed, it has a different pressure pattern, and a chamber located at one end on the end face of the sleep respiratory prevention pillow to induce the pillow posture into the original side and back. The pressure is supplied to the chamber and the pressure is discharged from the chamber located at the other end, so that the pressure between the chambers on the longitudinal section is asymmetric, thereby generating a warp to induce the sleeping posture to the side and above.

However, as shown in FIG. 5, when a sudden change occurs in a human body such as when a pillow user suddenly has an accident, optimal pressure pattern data, optimal sound pattern data, optimal pressure change data, stored in the memory device 50, And because optimal blood oxygen saturation data may be obsolete, the operating panel 28 is preferably configured to further select a learning mode to modify such data.

At this time, when the learning mode is selected in the operation panel 28, the artificial intelligence controller 60 repeatedly measures the pattern of pressure change for each chamber 22 during normal sleep, and thus forms a data type necessary for artificial intelligence control. It must be configured to store in memory.

While the pillow user is lying on the pillow main body 20 in a supine position, the process of storing the pressure pattern applied to each chamber 22 by maintaining a stable state of sleep or a similar degree for several minutes can be performed at a certain interval. By repeating it in turn.

As a result, since data stored in advance can be updated, data reflecting the generated body change can be stored and used for artificial intelligence control, and accurate determination of sleep respiratory disorder is possible.

On the other hand, since several people may use one pillow, when new data is input by learning, the old data is destroyed, so it is necessary to prevent this.

Thus, the operation panel 28 is preferably configured to include a user selection mode.

At this time, the memory device 50 should be configured to store in advance the data including the optimum pressure pattern data obtained by data- ing the pattern of the pressure change of each chamber 22 at the time of normal supine sleep for each user.

The artificial intelligence controller 60 is preferably configured to load data of the selected user when the user selection mode is selected and the user is selected.

This ensures that the pillow is available to several people because the data for the previous user is preserved when other users use the pillow during the long-term business trip of the pillow owner or when multiple users take turns using one pillow. Can be.

The sleep respiratory disorder preventing pillow according to the present invention detects the pressure for each chamber of the pillow, and compares it with a pre-stored optimal pressure pattern to determine the sleep respiratory disorder, if the pillow user is determined to be in a sleep respiratory disorder, the pillow By adjusting the pressure of each chamber so that the upper part of the user's head and the lower part of the neck are raised to open the upper respiratory tract, or by inducing the pillow user's sleeping posture to the side and side, a pillow for preventing sleep respiratory disorder can be solved. to provide.

Furthermore, an air cell is provided inside the chamber cell, so that the load of the head in contact with the pillow body can be naturally distributed and controlled within one chamber cell.

In addition, by providing a sound sensor, a vibration sensor, and blood oxygen saturation detection sensor on the pillow to determine the sleep breathing disorder, it is possible to determine whether the occurrence of a more accurate breathing disorder.

In addition, when the sleep posture of the pillow user is determined not to be the supine or lateral position, the pillow posture may be induced to be the supine or lateral position to prevent the occurrence of sleep respiratory disorder, and the change of the pillow user's body may occur. If you use a pillow or other users can prevent sleep respiratory disorders.
