Hereinafter, with reference to the accompanying drawings, an embodiment of the automatic posture conversion bed and its control method for posture correction of the obstructive sleep apnea patient according to the present invention will be described in more detail.

Referring to FIG. 1, an automatic posture converting bed for posture correction of a closed sleep apnea patient according to the present invention may include a mat part including at least two mats divided in a longitudinal direction in which a patient can lie down and a user lying down ( 10), the support 80 for supporting the mat unit 10 to a predetermined height, the elevating drive unit 20, which is installed in the lower portion of the mat unit 10 to push up each mat, the elevating drive unit 20 And an air supply unit 30 for supplying air for driving, and a position detecting unit 70 for detecting a current position of a patient is installed inside the mat unit 10, and surroundings of the mat unit 10. In the patient monitoring unit 50 and the occlusion section analysis unit 60 to determine whether the occlusion of the patient is installed, the patient position detection information through the position detection unit 70 and occlusion through the occlusion section analysis unit 60. Receiving recognition information and the lifting drive unit ( 20 is configured to include a control unit 40 for controlling.

With reference to Figure 2 looks at in detail the configuration of a specific automatic posture change bed. 2 is a general configuration diagram for explaining a posture change bed according to an embodiment of the present invention.

First, the mat unit 10 is configured to allow the user to lie down and sleep, and may be divided into a longitudinal direction in which the user is lying.

In FIG. 2, a state divided into three regions of the first mat 11, the second mat 12, and the third mat 13 is illustrated, but the present invention is not limited thereto. It may be divided into or divided into four or more areas.

Between the mats is provided with a pivoting hole (14) for hinge movement is made to fold or unfold the two adjacent mats. And the lower part of each mat is provided with a roller 15 to assist the smooth movement when the mat is folded or unfolded. The rollers 15 are respectively installed at the ends of the head of the mat (the head of the user lying down) and the foot of the foot (the foot of the user lying down), and the upper sliding guide 81 of the support 80 supporting the mat. Will move along.

On the other hand, the support 80 has a predetermined receiving space therein, and is configured to have a frame support structure that can support the mat of the mat portion 10 on the top. In particular, in the frame of the head portion and the foot portion in the upper portion of the support 80 is formed a sliding guide 81 that can support and guide the roller 15 of the mat in contact with it. The sliding guide 81 is formed as a groove for accommodating a certain portion of the roller 15 along the longitudinal direction and configured to accurately guide the direction of movement of the roller 15. In addition, stoppers 82 are formed at both ends of the sliding guide 81 to stop the movement of the roller 15 so that the mat is not separated from the support 80.

Meanwhile, in the support 80, a lift driver 20 for lifting each mat upwards is installed.

The lift driving unit 20 may be configured with a plurality of lifts, each lift is composed of air cylinders (21, 22a, 22b, 23) for raising and lowering the piston rod by the air supplied from the outside. Here, the piston rod has an upper end coupled to the bottom surface of the mat.

Each

air cylinder

21, 22a, 22b, 23 receives air through an air tube 25, which is connected to an air conditioning relay 24 to control the controller 40. Accordingly, opening and closing of the air tube 25 is controlled. Here, air is supplied from the air supply unit 30 to the air regulating relay 24.

At this time, the air cylinder (21, 22a, 22b, 23) is preferably a noise-free air cylinder with less noise during operation so as not to disturb the sleep of the user.

Here, the air cylinder 21 coupled to the lower portion of the first mat 11 is coupled to lift the first mat 11 from the outside (outside of the bed), so that the first mat 11 is lifted from the first mat 11. The outside of the first mat 11 is lifted while the portion adjacent to the second mat 12 is fixed, so that the first mat 11 is converted into a diagonal state as shown in FIG.

In addition, the air cylinder 23 coupled to the bottom of the third mat 13 is coupled to lift the third mat 13 from the outside (outside the bed), so that the second mat 13 in the third mat 13 is lifted. The outside of the third mat 13 is lifted while the portion adjacent to the mat 12 is fixed so that the third mat 13 is converted into a diagonal state as shown in FIG.

In addition, two sets of

air cylinders

22a and 22b are coupled to the lower portion of the second mat 12 in the center. This is to allow the corresponding second mat 12 to be inclined to the right or left to be switched to two diagonal states, respectively.

For example, when the air cylinder 22a on the left side operates, the left side of the second mat 12 will be lifted as shown in FIG. When the air cylinder 22b on the right side operates, the right side of the second mat 12 will be lifted as shown in FIG. 4 (d).

On the other hand, around the mat unit 10 is provided with a patient monitoring unit 50 for detecting whether the patient exhibits symptoms of occlusion during sleep.

For example, the patient monitoring unit 50 may be configured as a microphone 51. The microphone 51 collects the snoring sound of the sleeping patient, converts it into an electrical signal, and transmits it to the occlusion section analyzer 60. In general, when a person snoring during sleep, as the blockage progresses, the snoring sound increases in size and the frequency of the sound waves increases. Therefore, the occlusion section analysis unit 60 may determine whether the occlusion section (apnea section) is entered by comparing the delivered snoring sound signal with a sound size threshold or a sound wave frequency threshold for identifying entry into the occlusion section. Here, the sound size threshold or the sound wave frequency threshold of the occlusion section analyzer 60 may be individually set according to a user because there is an individual difference.

As another example, the patient monitoring unit 50 may be composed of a pulse wave sensor (52). The pulse wave sensor 52 may be worn on the user's thumb or index finger during sleep, and collects the pulse wave signal of the user in real time and transmits the pulse wave signal to the occlusion section analyzer 60. Accordingly, the occlusion section analyzer 60 may determine whether the occlusion section (apnea section) is entered by comparing the transmitted pulse wave signal with a pulsation threshold for identifying entry of the occlusion section. Here, the pulsation threshold of the occlusion section analyzer 60 may be individually set according to a user because there is an individual difference.

When the occlusion is detected as a result of the analysis of the above-described occlusion section analyzer 60, the detected occlusion signal will be transmitted to the controller 40.

On the other hand, the inside of the mat unit 10 will be provided with a position detection unit 70 that can detect the current position of the patient. The position detector 70 may be composed of a plurality of recognition sensors 71. Referring to FIG. 3, a plurality of recognition sensors 71 are built into the left mat 11, the center mat 12, and the right mat 13 constituting the mat unit 10 so that the current user is in any position at any position. Make sure you can see if you're lying down.

For example, the recognition sensor 10 may be configured as a pressure sensor. When the user is located in the mat, the pressure sensor detects the pressure due to the weight of the user and transmits the position recognition signal to the controller 40.

As another example, the recognition sensor 10 may be configured as a temperature sensor. When the user is located in the mat, the temperature sensor will detect the temperature due to the user's body temperature and transmit a location recognition signal to the control unit 40.

The control unit 40 which receives the recognition signals from the above-described recognition sensors 10 may determine in real time which mat the user is currently positioned on and which posture he or she has through a preset position value of the recognition sensor 10. It becomes possible. Here, the current sleeping posture recognition of the user may be achieved by arranging the recognition sensor 10 in a net form.

On the other hand, when the control unit 40 receives the occlusion signal according to the occlusion detection from the occlusion section analyzer 60, the control unit 40 controls the lift driving unit 20 to lift some of the mats of the mat unit 10. Your sleep posture will be corrected.

More specifically, the control unit 40 may lift the mat on which the user is located by referring to the current sleeping position and the sleeping posture of the user, which are identified through the recognition signal from the position detecting unit 70 after receiving the occlusion signal. . Through this, the mat of the bed is converted from the horizontal state to the oblique state, and the user on it is naturally twisted and lying on the side, and through this, the airway is secured and the apnea is released.

Referring to FIG. 4, when the user detects an occlusion during sleep at the position of the first mat 11, as shown in FIG. 4A, the air cylinder 21 is operated to operate the first mat 11. By lifting and transforming the first mat 11 in an oblique manner, the user can be naturally turned sideways on the second mat 12.

In addition, when the user detects blockage during sleep at the position of the third mat 13, as shown in FIG. 4B, the air cylinder 23 is operated to lift the third mat 13 to raise the third mat. By converting (13) to an oblique line, the user can naturally be turned sideways on the second mat (12).

In addition, when the user detects an occlusion during sleep at the position of the second mat 12, as shown in FIG. 4C, the air cylinder 22a is operated to lift the second mat 12 to lift the second mat. By converting the posture 12 into a diagonal shape, the user can naturally be turned sideways on the third mat 12.

On the contrary, if the user selectively detects an occlusion during sleep at the position of the second mat 12, as shown in FIG. 4D, the air cylinder 22b is operated to lift the second mat 12. Posture transformation of the second mat 12 in an oblique shape can naturally cause the user to turn sideways on the first mat 11.

Occasionally, the occlusion of the user may persist even after the posture change of the mat. This is because when the user's mat is converted from the horizontal state to the oblique state, the user is not guided to the lying sideways position, but is naturally pushed from the oblique mat and moved to the horizontal mat to maintain the lying position.

In order to prevent the occlusion maintenance situation, when the obstruction continues even after the oblique state control of the mat where the user is located as described above, the control unit 40 lifts the mat at the position where the user is currently sleeping and the adjacent mat together. It raises a valley using two adjacent mats to induce the user to lie on the side naturally.

Referring to FIG. 4, when the user keeps the occlusion even in a diagonal state of the first mat 11 or the second mat 12, the

air cylinders

21 and 22b may be removed as shown in FIG. 4E. By working together, the first mat 11 and the second mat 12 are lifted together to create a valley, which induces the user to naturally lie on the side of the valley.

In addition, when the user keeps the occlusion even in the oblique state of the second mat 12 or the third mat 13, as shown in (f) of FIG. 4, the

air cylinders

22a and 23 are operated together to form the second mat. The mat 12 and the third mat 13 are lifted together to make a valley, thereby inducing a user to naturally lie on the side of the valley.

Now with reference to FIG. 5 will be described the overall control method of the posture change bed according to an embodiment of the present invention.

First, as a step S10, the user is sleeping on the mat unit 10, accordingly the patient detection unit 50 monitors the user's sleep state, using the monitoring information occlusion section analysis unit 60 It will be determined whether the user enters the occlusion section.

Next, the control unit 40 determines whether an occlusion is detected through whether an occlusion signal is transmitted from the occlusion section analysis unit 60 (S12), and when the occlusion is detected, the control unit 40 determines the presence of the current user. Location and posture will be detected (S14).

Next, the control unit 40 controls the air conditioning relay 24 based on the detected position and posture of the user to supply air to the air cylinder of the mat where the user is located, thereby providing the mat with FIGS. It is raised as shown in (d) (S16). As a result, the mat can be transformed into an oblique shape, and the user can naturally lie on the side.

Thereafter, the controller 40 continuously monitors the sleep state of the user through the patient detecting unit 50 to determine whether the occlusion of the user is continued (S18).

At this time, if the occlusion of the user continues, the control unit 40 controls the air conditioning relay 24 to lift the mat of the position where the user is currently sleeping and the adjacent mat together to use two adjacent mats. As shown in 4 (e) to (f) to make a valley (valley) (S20). Accordingly, the user located in the goal is naturally induced to lie on the side.
