This second connection portion 19 is preferably made of a rubber material that can be transformed into a curved shape, but various materials that can be transformed into various curves by manipulation by the infant or the parent of the infant can be used, so it is not limited to this. No.

Next, the control unit 100 included in the smart infant stethoscope toy 10 will be described with reference to FIG. 6 .

Figure 6 is a block diagram of the smart infant stethoscope toy of Figure 1.

As shown in Figure 6, the smart infant stethoscope toy 10 includes a sensor unit 105 including a temperature sensor 1051, a pulse wave sensor 1053, an oxygen saturation sensor 1055, and a skin detection sensor 1057; It may include an otitis media treatment lamp 120, a control unit 100, an output unit 110, a storage unit 130, and a communication unit 150.

The sensor unit 105 includes a temperature sensor 1051, a pulse wave sensor 1053, an oxygen saturation sensor 1055, and a skin detection sensor 1057 provided in the insertion unit 11 and the head unit 13. Measure your vital signs.

Accordingly, the control unit 100 determines the infant's health status based on the infant's biological signals measured by the sensor unit 105. At this time, the control unit 100 can control the operation of each sensor included in the sensor unit 105 to measure the infant's body temperature, heart rate, oxygen saturation, and electrical conductivity as the infant's biological signals.

Meanwhile, the temperature sensor 1051 of the sensor unit 105 is provided inside the first insertion unit and operates under the control of the control unit 100 to measure the body temperature value inside the infant's ear. More specifically, the temperature sensor 1051 is a type of infrared non-contact temperature sensor that detects changes in infrared rays by emitting infrared rays inside the infant's ear, and can measure the body temperature value by inferring the infant's temperature according to the detected infrared changes. .

Accordingly, the smart infant stethoscope toy 10 can measure the infant's body temperature value when the first insertion part 111 is inserted into the infant's ear.

Next, the pulse wave (PPG: Photoplethysmography) sensor 1053 is provided to measure changes in blood flow due to heartbeat, that is, pulse waves, and is exposed from the inside of the grip portion 131 to the outside of the contact groove (H). When the infant's hand grasps the grip part 131 and a part of the finger touches the contact groove (H), the change in blood flow due to heartbeat can be measured.

The pulse wave sensor 1053 may use a reflective pulse wave (PPG: Photoplethysmography) sensor that measures a signal that is reflected and returned after a light source is transmitted through the skin.

For example, the pulse wave sensor 1053 is configured to include a light emitting source and a light receiver, so when light projected from the light source is irradiated onto the human body, light is absorbed in the blood, bones, and tissues, and some of the light is reflected. Light is received by the receiver. The information absorbed by light is proportional to the amount of skin, tissue, and blood in the path through which the light passes, and does not change except for changes in blood flow due to heartbeat, so changes in blood flow can be measured using reflected light.

In this regard, the oxygen saturation (SpO2, Saturation of Percutaneous Oxygen) sensor 1055 is provided to measure the concentration of oxygen in arterial blood. Like the pulse wave sensor 1053, the contact groove ( H) It is provided in a form exposed to the outside, so that the infant's hand grasps the grip part 131 and a part of the finger touches the contact groove (H), so that oxygen saturation can be measured.

Although the pulse wave sensor 1053 and the oxygen saturation sensor 1055 are shown in the drawing as separate blocks to easily explain the configuration of the present invention, the pulse wave sensor 1053 and the oxygen saturation sensor 1055 are integrated. It can be prepared as a single biosensor. In other words, it can be configured as a multi-function biosensor that can measure both pulse wave and oxygen saturation in one biosensor.

Accordingly, the smart infant stethoscope toy 10 can simultaneously measure pulse waves and oxygen saturation when an infant grasps the grip part 131 and a part of the finger touches the contact groove (H).

Meanwhile, the skin detection (GSR, Galvanic Skin Response) sensor 1057 is provided to measure the skin conductivity of the infant's body skin, and is provided in a form that protrudes from the inside of the contact part 133 to the outside. When contacting the body of an infant or child, electrical conductivity can be measured by detecting changes in skin resistance.

The skin detection sensor 1057 can determine emotional changes by measuring the electrical conductivity of an infant's body through the principle that when a person secretes sweat, the electrical conductivity of the skin increases due to the sodium component of sweat.

In addition, the skin detection sensor 1057, although not shown in the drawing, may be provided as a biosensor integrated with a temperature and humidity sensor capable of measuring skin surface temperature and humidity. Here, the temperature and humidity sensor may be a sensor (DHT11) that measures the temperature and humidity of the body using a capacitive humidity sensor and a thermistor and outputs the measured value as a digital sensor signal. In other words, the skin detection sensor 1057 can be combined with the temperature and humidity sensor to form a multi-function biosensor that can measure both the electrical conductivity of the infant's body and the temperature and humidity of the body's skin in a single sensor.

Accordingly, the smart infant stethoscope toy (10) excludes the temperature sensor (1051) in the insertion part (11), and when only a plurality of otitis media treatment lamps are provided, a bio-sensor provided as a skin detection sensor (1057) and a temperature and humidity sensor is provided in the insertion part (11). Through this, the smart infant stethoscope toy (10) uses a biosensor to measure the infant's body temperature, and when the contact part (133) touches the infant's body, emotional changes and changes occur according to the infant's electrical conductivity. The temperature and humidity of infants' skin can be measured.

Meanwhile, the otitis media treatment lamp 120 is provided to treat otitis media existing inside the ears of infants and children, and is provided in a form that protrudes from the inside of the second insertion part 113 to the outside, and when inserted into the ears of infants and children, the control unit ( Otitis media can be treated by operating under the control of 100).

This otitis media treatment lamp 120 emits an LED light source with a wavelength that is highly effective in treating inflammation, and the light is irradiated to the middle ear inside the ear, thereby treating otitis media.

In this regard, looking at the known studies on the anti-inflammatory effect of LED, studies were mainly conducted on wavelengths of 630 to 680 nm, and Choi et al. reported a decrease in proinflammatory cytokines in the MAPK signaling pathway by LED irradiation. According to a study by Lim et al., when irradiating LED with a wavelength of 635 nm and comparing its effect with NSAID, LED irradiation, unlike NSAID, directly dissociates reactive oxygen species (ROS) or, as a result, cytosolic phospholipase A2, secretary It has been reported that it suppresses the mRNA expression of phospholipase A2 and cyclooxygenase (COX), thereby suppressing PGE2, resulting in an effect similar to NSAID. Additionally, Nomura et al. irradiated human gingival fibroblasts with LED and reported a decrease in IL-1beta produced by LPS in the oral cavity.

Accordingly, the smart infant stethoscope toy 10 can treat otitis media in infants and toddlers playing by controlling the otitis media treatment lamp 120, which emits an LED light source having this effect, through the control unit 100.

Meanwhile, the smart infant stethoscope toy 10 includes biological signals measured by the communication unit 150 and the sensor unit 105 that communicate with the infant parent terminal 20, and normal range information for determining whether each biological signal is normal. It may include a storage unit 130 for storing and an output unit 110 for outputting heart sounds, which will be described later. Here, the normal range information may include a normal body temperature range, normal heart rate range, normal humidity range, and normal skin conductance range based on the infant's known health information.

In this regard, the normal body temperature range for infants and children based on known health information is 36.1˚ to 38˚, normal heart rate range is 120 to 160 beats, normal humidity range is 15% to 20%, and normal skin conductance range is It can be set to 1 (uS) to 13 (uS). Here, the normal heart rate range can be set based on the age of the infant, so it is not limited thereto.

Next, the storage unit 130, which corresponds to a data storage memory, records biological signals measured in the sensor unit 105 in real time from the time the power supply to the smart infant stethoscope toy 10 starts by the power unit 15. You can save it.

In addition, the storage unit 130 stores software (application) for determining the health status of an infant, and the control unit 100 may store a preset algorithm for determining the health status of the infant based on biological signals. . At this time, the control unit 100 may determine the infant's health status using a preset algorithm stored in the storage unit 130.

As shown in FIG. 3, when the control unit 100 inserts the insertion part 11 into the ear and plays by holding the head part 13, the temperature sensor provided inside the first insertion part 111 By controlling (1051), the body temperature value inside the infant's ear can be measured.

At this time, the control unit 100 may compare the normal temperature range stored in the storage unit 130 with the infant's body temperature value measured by the temperature sensor 1051 of the sensor unit 105.

Here, if the infant's body temperature value measured by the temperature sensor 1051 is within the known infant's normal body temperature range, the control unit 100 determines the temperature to be normal, and if it is higher than the normal body temperature range, the control unit 100 determines the infant's body temperature to be high fever. If it is less than this range, it can be judged as hypothermia.

Thereafter, the control unit 100 may control any one of the pulse wave sensor 1053, oxygen saturation sensor 1055, and skin detection sensor 1057 of the sensor unit 105 to further measure the infant's biological signals. .

Accordingly, the control unit 100 controls the biosensor consisting of the pulse wave sensor 1053 and the oxygen saturation sensor 1055 to measure the pulse wave signal and oxygen saturation for a preset time, and stores the measured pulse wave signal in the storage unit 130. It can be compared with normal heart rate information stored in . Here, the preset time may be set at 1-minute intervals, but is not limited to this.

In this regard, the control unit 100 compares the pulse wave signal and the normal heart rate range and, if the pulse wave signal is within the normal heart rate range, determines the infant's respiratory state as normal breathing, and if it is higher than the normal heart rate range, determines the infant's respiratory state. It can be judged as hyperventilation.

In addition, the control unit 100 controls a biosensor consisting of a skin detection sensor 1057 and a temperature and humidity sensor to measure skin conductivity and skin moisture rate of infants and toddlers, and stores the measured skin conductivity as normal skin conductivity stored in the storage unit 130. The measured skin humidity rate can be compared with the normal humidity range stored in the storage unit 130.

Accordingly, the control unit 100 may determine the infant's stress state by comparing the measured skin conductance of the infant and the normal skin conductance range. Accordingly, the control unit 100 determines that the infant is in a normal state without stress when the measured skin conductivity of the infant is within the normal skin conductivity range, and when the measured skin conductivity of the infant is higher than the normal skin conductance range. , depending on the value compared to the normal skin conductance range, the infant's stress state can be judged as irritable or angry.

Additionally, the control unit 100 may determine the dry skin condition of the infant or child by comparing the measured skin humidity rate of the infant or child with the normal humidity range. Accordingly, the control unit 100 determines that the infant's skin is in a normal state when the measured humidity rate of the infant is within the normal humidity range, and when the measured humidity rate of the infant is lower than the normal humidity range, the control unit 100 determines that the infant's skin is in a normal state. It can be determined that the skin is dry.

Subsequently, the control unit 100 may determine the health status by inputting bio-signals into a preset algorithm stored in the storage unit 130. Here, the control unit 100 can generate one data set by combining each biological signal measured by the sensor unit 105.

At this time, the control unit 100 may determine the infant's health status by inputting a data set generated by combining each biological signal with a preset algorithm stored in the storage unit 130. For example, the algorithm outputs the infant's health status as normal if each bio signal present in the dataset is normal, and among each bio signal, the body temperature state is high fever, the breathing state is hyperventilation, and If the stress state and dry skin state are normal, the infant's health state is output as a cold state. Among each vital signal, the body temperature state is high fever, the stress state is angry state, and the respiratory state and skin dry state are normal, the infant or child's health state is output as cold state. The health status is output as otitis media, and if the stress state is irritated, the dry skin is dry, and the body temperature and breathing are normal, the infant's health status is output as atopy.

Accordingly, the control unit 100 determines the health status of the infant using a preset algorithm stored in the storage unit 130, but when the health status of the infant is otitis media, the health status of the infant is otitis media provided in the insertion unit 11. The otitis media treatment lamp 120 can be controlled to operate for a preset time.

Through this, the control unit 100 can treat otitis media present inside the ears of infants and toddlers playing with the smart infant stethoscope toy 10 without fear of treatment.

Meanwhile, the control unit 100 may further generate a heart sound based on the pulse wave signal and oxygen saturation among each biological signal measured by the sensor unit 105. To this end, a separate algorithm that is different from the algorithm that outputs the infant's health status may be further stored in the storage unit 130. Here, a separate algorithm may be a pre-set algorithm that preprocesses the pulse wave signal and oxygen saturation into data values, inputs the preprocessed data values to the deep learning model, and outputs heart sounds.

The control unit 100 inputs the pulse wave signal and oxygen saturation into a separate algorithm stored in the storage unit 130 to generate heart sounds of infants and toddlers playing and outputs them by controlling the output unit 110. To this end, the head unit 13 may further include a speaker unit 135 for outputting the heart sound output from the output unit 110 to the outside.

Accordingly, the control unit 100 can increase the play concentration of infants and toddlers playing through the smart infant stethoscope toy 10, and infants and toddlers can directly hear their own heart sounds, thereby arousing interest in their own health.

Meanwhile, Figure 7 is a diagram of an infant monitoring system including the smart infant stethoscope toy of Fig. 1.
