Therefore, the measurement of sleep quality is the focus of modern medical and healthy life research. .

The existing sleep detection technology needs to capture multiple physiological signals in order to observe which sleep stage and sleep state the human body enters. The sleep detection provided by general medical places mostly adopts sleep polysomnography (PSG), using several sensors. The sensor is attached to the person under test. Many sensors use wired sensors. This state is very different from the usual sleep state at home. It is easy to cause discomfort during sleep of the person under test and reduce the accuracy of sleep measurement results.

In response to the above problems, a sleep sensing device with a simpler structure has been proposed. For example, a micro electrocardiogram (ECG) device is used with a smart bracelet to capture multiple sensing information for preliminary sleep detection. The smart bracelet generally uses light volume changes. Photoplethysmography (PPG) is used to measure heart rate in order to indirectly determine sleep status. Most of the above measurement methods use wireless portable devices, which have little interference to the sleep of the tested person, can improve the quality of sleep, and the cost of obtaining the device is also low, and the general public is willing to use it, but this type of device is matched because of the measurement accuracy. Low, it is only available for the testees to make a preliminary sleep quality status reference. Professional medical personnel cannot provide more accurate information. This part of the information cannot be used for advanced diagnosis. At present, it is still unable to replace the PSG detection method.

In view of the above-mentioned problems, the present invention discloses a sleep sensing system, which helps To solve the problem of human body discomfort caused by wearing a sleep sensing device and improve the accuracy of sleep sensing results.

The present model provides a sleep sensing system, which includes an arithmetic device, a heart inductance sensor, a blood oxygen sensor and an eye movement sensor. The eye movement sensor includes an eye electrical sensor, which includes a first electrode and a second electrode. The first electrode and the second electrode are mounted on a breathable patch so as to be arranged on the peripheral epidermis of an eye of the subject, and the first electrode and the second electrode are arranged vertically or horizontally. The cardiac electrical sensor, blood oxygen sensor and eye movement sensor are all connected to the computing device in telecommunication.

The present invention also provides a sleep sensing system, which includes a heart sensor, a blood oxygen sensor, an eye movement sensor, and an arithmetic device. Among them, the eye movement sensor includes an eye movement accelerometer. The cardiac electrical sensor, blood oxygen sensor and eye movement sensor are all connected to the computing device in telecommunication.

According to the sleep sensing system disclosed in the present invention, the sleep sensing system can sense one or more physiological signals, including capturing eye movement signals via an eye movement sensor, capturing electrocardiographic signals via a cardiometric sensor, and via The blood oxygen sensor captures the blood oxygen signal. Thereby, the component composition of the sleep sensing system can be simplified, and even if the subject wears the sleep sensing system, the sleep quality will not be excessively disturbed. In addition, compared to the existing non-medical-grade sleep detection that uses a single device to check multiple physiological signals, the sleep sensing system disclosed in the present invention includes multiple sensors that can independently check different physiological signals and is based on physiological signals. The type of sensor is placed on the corresponding body part, which helps to improve the measurement accuracy.

The following examples further illustrate the viewpoint of the present invention in detail, but do not limit the scope of the present invention by any viewpoint.

The invention provides a sleep sensing system, which includes an arithmetic device, a heart inductance sensor, a blood oxygen sensor and an eye movement sensor. The eye movement sensor includes an eye electrical sensor, which includes a first electrode and a second electrode. The first electrode and the second electrode are mounted on a breathable patch so as to be arranged on the peripheral epidermis of an eye of the subject, and the first electrode and the second electrode are arranged vertically or horizontally. Thereby, the structure of the ocular sensor is simplified, which can reduce component cost and power consumption. According to actual needs, the ocular sensor can further include amplifiers, analog-to-digital converters, microprocessors, power management, batteries, electrode contacts, communication contacts or Bluetooth chips.

The ocular electrical sensor may further include a third electrode. The first electrode, the second electrode and the third electrode are arranged in an L-shape and arranged on the peripheral epidermis of the eye. In addition, the ocular electrical sensor can also include a fourth electrode, and the third electrode and the fourth electrode can be arranged on the peripheral epidermis of the other eye of the subject, and the third electrode and the fourth electrode correspond to the first electrode and the fourth electrode. The two electrodes present a symmetrical configuration for the left and right eyes. In this way, the eye movement sensor can detect eye movements in multiple directions, and can obtain more types of subject information, thereby more accurately determining the subject's current sleep state.

The shortest distance between the electrodes of the ocular electrical sensor is De, which can satisfy the following state: 10 millimeters (mm)<De. In some cases, the following conditions can be met: 15mm<De<50mm. In this way, a sufficient number of electrodes can be arranged around the eyes of the subject, and a sufficient potential difference between the electrodes can be obtained to obtain sufficient sensing accuracy. At the same time, it can prevent the subject from having too large an electrode patch distribution range. Feel uncomfortable wearing.

The present invention also provides a sleep sensing system, which includes an arithmetic device, a heart sensor, a blood oxygen sensor, and an eye movement sensor, and the eye movement sensor includes an eye movement accelerometer. Among them, the eye movement accelerometer can be a three-axis accelerometer or a six-axis accelerometer. When using a three-axis accelerometer, the structure of the eye movement sensor is simplified, which can reduce component cost and power consumption. When using six When the axis accelerometer is used, it can measure the forward, lateral, or up and down vibration and rotation, so more kinds of movement information of the subject can be obtained, and then the current sleep state of the subject can be more accurately judged.

The electrocardiogram can be a device for recording an electrocardiogram, and the electrocardiogram can be attached to the torso of the subject, such as the surface of the skin around the subject's heart. Among them, the cardiac inductance sensor can be a circular sensor with a diameter of less than 60 millimeters (mm), so as to further miniaturize the cardiac inductance sensor. Among them, the electrocardiograph may have a plurality of channels (Channel) of the number of electrodes, so as to use more sets of measurement information for error detection and optimization. Specifically, the electrocardiograph can be dual-channel, and has a total of three electrodes distributed at each end of the regular triangle.

The blood oxygen sensor can be a pulse oximeter (Pulse oximeter), and the pulse oximeter can be a penetrating type, which can be clamped on the tip of the subject’s finger or earlobe to reduce the skin and muscles The tissue hinders the signal capture, thereby improving the quality of the captured signal; or, the blood oxygen sensor can be a bracelet or ring that is put on the wrist or finger, and the blood oxygen sensor can use the photovolume tracing method Therefore, the use of more mature measurement technology can provide a more affordable and comfortable blood oxygen sensor.

The eye movement accelerometer of the eye movement sensor can be configured within the eye socket, and the eye movement accelerometer is connected with the eyeball through the eyelid. The eyelid skin is thin and will not interfere with the measurement of the eye movement sensor, which helps to improve The measurement sensitivity of the sensor, and at the same time, there are fewer neurons in the eyelid area, which can reduce the foreign body sensation and discomfort caused by the subject wearing the sensor. Furthermore, the eye movement sensor may be configured on the surface of the upper eyelid or the surface of the lower eyelid of the subject. Since the eye movement accelerometer measures eye movement, it needs to be placed in an area where eye movement can be sensed, such as the eye socket. The orbital area is based on the area where feedback can be obtained by lightly squeezing the eyeball through the eyelid.

The eye movement sensor may include a sensor body and a sensing part. The sensor body can be configured on the subject's forehead, and it includes a microcontroller (MCU), a battery, a power management IC (Power IC), a memory, and an I/O interface. Wherein, the sensing part includes an eye movement accelerometer, which can be arranged on the surface of the upper eyelid. Through the separation of the sensing part and the sensor body, the volume of the sensing part can be reduced. Therefore, when the sensing part is arranged on the eyelid, the comfort of the subject wearing the sensor can be improved.

The sensor body of the eye movement sensor can be arranged on the cheek of the subject, and the sensing part includes an eye movement accelerometer, which can be arranged on the surface of the lower eyelid. In this way, the volume of the sensing part can be reduced.

The sensor body of the eye movement sensor can be clamped on the nose bridge of the subject, and the sensing part includes an eye movement accelerometer, which can be arranged on the inner eyelid surface around the nose bridge. In the case where the eye movement sensor is equipped with high-specification components, which results in heavier weight, the nose bridge can be used to support the sensor body, which can provide a more comfortable wearing feeling than arranging the sensor body on the eyes. Among them, the eye movement sensor can also be a spectacle frame arranged on the bridge of the nose. When the eye movement sensor is arranged on the bridge of the nose, the main body of the sensor can be a flexible flexible plate, and the battery and other ICs are used to weight both sides of the nose bridge.

The eye movement sensor can be configured on the sleep goggles, and the sleep goggles are connected with the eye lids. In this way, the eye mask provides a larger internal accommodating space or surface area, so that the various components in the eye movement sensor can be dispersedly arranged, thereby providing a more suitable weight and component heat dissipation distribution. Among them, the eye movement sensor can be integrated into the massage eye mask.

The eye movement sensor can be a miniature sensor, and the miniature sensor is built into a contact lens; thereby, the contact lens can be used to directly contact the eyeball to bring the eye movement sensor closer to the eyeball, thereby providing high sensitivity Of eye movement sensing information. Furthermore, the contact lens can be a sandwich stack structure, and the eye movement sensor can be arranged in the middle inner layer of the contact lens to avoid direct contact between the sensor element and the eyeball, and the eye movement sensor is located in the non-optically effective contact lens. Zone, can prevent the sensor from blocking the line of sight.

When the eye movement sensor is configured in the contact lens, the eye movement sensor can be changed to a passive electromagnetic sensor (such as a passive RFID or NFC tag), and then the eye mask is used for electromagnetic sensing. When the sensor mounted on the contact lens is displaced or rotated through eye movement, a current is generated due to the change in the magnetic field and a signal of eye movement is sent out. When the eye movement sensor is a passive electromagnetic sensor, there is no need to configure a power source (such as a battery) on the contact lens, which can make the contact lens equipped with the eye movement sensor lighter and thinner. Comfortable.

When the eye movement sensor is configured in the contact lens, it can be equipped with a thermoelectric power generation module. The thermoelectric power generation module is mounted in the contact lens and can use human body temperature and heat to generate electricity. With the thermoelectric power generation module, the eye movement sensor and the thermoelectric power generation module can be configured in hard glass contact lenses to improve the heat transfer efficiency and simultaneously perform squeeze myopia control. When wearing hard glass contact lenses with eye movement sensors and thermoelectric power generation modules, there is no need to configure a power source on the contact lenses. At the same time, hard glass contact lenses can be used as corneal shaping lenses to measure sleep information and correct myopia. Can be done together.

The sleep sensing system disclosed in the present invention may further include a head motion sensor and an integrated motion sensor. The head movement sensor can be a three-axis or six-axis accelerometer. The body motion sensor may include an integrated motion accelerometer, and the body motion sensor is disposed on the torso of the tested human body. Both the head movement sensor and the body movement sensor are used to determine whether the subject is asleep or awake in order to perform sleep REM sensing and recording, so as to reduce misjudgment of the sleep state and avoid the activation of sleep eye movement sensing or heart movement during the waking state. Inductance measurement. If a headless motion sensor or a body motion sensor can only distinguish eye rotation, head rotation, or body movement from the acceleration measured by the accelerometer, the above distinction needs to rely on the medical examiner’s own experience, so The judgment result lacks reliability and accuracy. In the case of an additional head motion sensor or body motion sensor in the new model, the acceleration measured by the head motion sensor and/or body motion sensor can be used as auxiliary data to determine the eye motion accelerometer measurement Whether the acceleration of is the acceleration generated by the eyeball rotation, thereby improving the measurement accuracy.

The body motion sensor can be used with a cardiac electrical sensor or a blood oxygen sensor. In the case of a body motion sensor with a blood oxygen sensor, the blood oxygen sensor and the body motion sensor can be mounted on the bracelet. In this way, the sensor can be integrated into a smart bracelet or a bracelet with an RFID (Radio Frequency Identification) tag on the market, making it easier for the subject to wear and feel more comfortable.

The eye movement accelerometer and the head movement sensor of the eye movement sensor can both be accelerometers with the same axial number, for example, both three-axis or six-axis accelerometers, so as to compare and distinguish the state of eye movement or body movement. In this way, it can be avoided that the eye movement accelerometer can measure acceleration in a certain vibration direction but the head movement sensor cannot measure it. Therefore, the acceleration measured by the head movement sensor can be used as a reliable auxiliary data to judge the eye Whether the acceleration measured by the dynamic accelerometer belongs to the acceleration generated by the eyeball rotation.

Cardiovascular sensor, blood oxygen sensor and eye movement sensor each can have wireless transmission Module. The wireless transmission module adopts radio wave related transmission technology. In this way, the sleep sensing system can communicate with each sensor without using wires, which can prevent the subject from feeling uncomfortable due to the entanglement of the body with the wires. In addition, the sleep sensing system can be omitted without the use of wires. The cable management structure helps to simplify the number of components in the sleep sensing system.

The various technical features in the above-mentioned novel sleep sensing system can be combined and configured to achieve corresponding effects.

FIG. 14 shows a flowchart of sleep sensing according to an embodiment of the present invention. The sleep sensing system senses one or more physiological signals, including capturing nystagmus signals via an eye movement sensor (or an ocular electrical sensor), capturing an electrocardiographic signal via an electrocardiographic sensor, and capturing a body motion sensor Body movement signals and blood oxygen signals captured by the blood oxygen sensor. These physiological signals undergo feature extraction through signal pre-processing to obtain feature values. Perform classification and frequency calculations on the characteristic values to finally obtain a sleep analysis report, and the content of the sleep analysis report may include sleep stage, sleep position, frequency and type of respiratory cessation, and frequency of body movement.

According to the sleep sensing system disclosed in the present invention, the electrocardiogram sensor, the blood oxygen sensor, and the eye movement sensor are all connected to the computing device telecommunications to realize physiological signal transmission, feature extraction and calculation. Electrocardiogram sensors, blood oxygen sensors, and eye movement sensors can all be telecommunications connected to computing devices via wired or wireless means. In the case that the sleep sensing system further includes other sensors, these other sensors may also be telecommunications connected with the computing device. The computing device can be an independent device or a unit built into the sensor. For example, the computing device can be a server, a computer host, or a smart phone. On the other hand, the arithmetic device can also be a special application integrated circuit arranged inside any sensor.
