At this time, the user looks at the mirror 205. The infrared sensor array unit 210 on the mirror 205 in synchronization with blood pressure measurement in the blood pressure measurement unit 300 detects a thermal image on the face of the user and measures the body temperature of the face.

The measured body temperature and blood pressure are displayed through the display unit 120.

The key input unit 160 includes a power switch, an operation start switch, and the like. In addition, basic information for each patient can be entered.

The operation processing unit 150 transmits a blood pressure measurement start signal to the blood pressure detection control unit 350 of the blood pressure measurement unit 300 when the key signal of the operation start switch is input and simultaneously transmits the blood pressure measurement start signal to the body temperature detection control unit 350 of the body temperature measurement unit 200 (250).

The main memory unit 180 stores the body temperature signal and the blood pressure signal received from the arithmetic processing unit 150 for each patient.

When the alarm unit 170 receives a warning signal such as a dangerous state from the operation processing unit 150, the alarm unit 170 informs the buzzer or the speaker of the dangerous state.

The LED display unit 175 emits an LED (light emitting diode) to indicate that it is in operation or operation, or it is in a dangerous state.

The power unit 190 converts power from an external power source or a battery power source into a power suitable for driving the main module unit 100, the body temperature measurement unit 200, and the blood pressure measurement unit 300, The driving power source of the body temperature measuring unit 200, and the driving power source of the blood pressure measuring unit 300.

The infrared sensor array unit 210 detects a thermal image of a user's face using an infrared sensor array.

As the infrared sensor array, a thermopile array sensor (TAS: Themopile Array Sensor) can be used. A commercially available thermopile array sensor is a module in which a plurality of thermopile sensors are arranged in square (for example, 32 x 32) pixels to measure the temperature of each subregion (for example, 32 x 32) of a specific object The thermopile array sensor includes a temperature sensor (TS) for measuring the temperature inside the module, such as a thermistor. The temperature sensor TS outputs an electric signal corresponding to the temperature inside the module, and the thermopile array sensor receives infrared rays generated in each partial region of a specific object on a pixel-by-pixel basis, And outputs the electric signals.

The body temperature information signal preprocessing unit 230 includes an amplifier (not shown) and a filter (not shown). The amplifier amplifies electric signals output from the infrared sensor array unit 210, that is, the thermopile array sensor, The temperature information signal is amplified. The filter, as a low-pass filter, removes the noise of high frequency components introduced into the electric signal outputted from the amplifier, that is, the body temperature information signal.

The A / D conversion unit 240 converts the electrical signal output from the body temperature information signal preprocessing unit 230, that is, the body temperature information signal, into a digital signal, and transmits the digital signal to the body temperature detection controller 250.

The output electrical signal of the temperature sensor TS, which is provided inside the thermopile array sensor and is a sensor for electrically detecting the temperature inside the thermopile array sensor, is also converted into an analog signal through the A / D converter And transmits it to the body temperature detection control unit 250.

The body temperature detection control unit 250 is a means for controlling the body temperature measuring unit 200 as a whole and includes an infrared sensor array unit 210, The skin temperature of the face is detected from the signal received through the conversion unit 240, that is, the body temperature information signal, and the body temperature is obtained therefrom.

The body temperature detection control unit 250 is a means for controlling the body temperature measurement unit 200. The body temperature detection control unit 250 receives a body temperature measurement start signal from the calculation processing unit 150 of the main module unit 100, The driving of the body temperature detection control unit 250 starts.

The body temperature detection control unit 250 adjusts each pixel obtained from the body temperature information signal received through the A / D converter 240, that is, the thermopile array sensor, to a predetermined size by using calibration data. After the temperature information signal thus adjusted is compared with the ambient temperature, the difference value is calculated, the partial temperature of the face is measured, and the temperature is obtained for each pixel to obtain the thermal distribution state of the skin, that is, the skin temperature.

Here, the ambient temperature may be a predetermined temperature, and may be a temperature detected by a temperature sensor TS provided inside the thermopile array sensor.

For example, if the temperature inside the module measured by the temperature sensor TS is 15 degrees and the infrared sensor array unit 210, i.e., the first pixel P (1,1) of the thermopile array sensor, If the temperature of the first partial region of the measured specific object is 46 degrees, the temperature difference value is calculated to measure the temperature of the first partial region as 31 degrees, and the infrared sensor array unit 210, If the temperature of the second partial region of the specific object measured by the second pixel P (1,2) of the sensor is 47 degrees, the temperature difference value is calculated, and the temperature of the second partial region is set to 32 degrees . In this way, an infrared image corresponding to the temperature difference value of each partial area is generated. Through this, the heat distribution state of the face can be known. That is, the skin temperature can be obtained in this manner.

The average skin temperature is averaged from the skin temperature, that is, the skin temperature of each part is averaged, and the body temperature is converted using the body temperature conversion data. The obtained body temperature value is stored in the body temperature detection memory unit 280 or transmitted to the main module unit 100.

The body temperature detection memory unit 280 includes calibration data, body temperature conversion data, and the like.

The blood pressure measuring unit 300 includes a cuff 310, a pressure sensor unit 320, a blood pressure signal preprocessing unit 330, an A / D conversion unit 340, a blood pressure detection control unit 350, a blood pressure detection memory unit 380, A pneumatic motor 360, a motor driving unit 365, an exhaust valve 370, and an exhaust valve driving unit 375.

The cuff 310 has an air pocket (not shown) inside and is connected to an air storage (not shown) through a tube (not shown) connected to the air pocket. The amount of air entering the air bag from the air storage unit (not shown) through the air passage tube is regulated by a pneumatic motor 360. That is, the pneumatic motor 360 presses the cuff 310, i.e., the air bag. The air passage tube is also connected to an exhaust valve 370 so that the exhaust valve 370 decompresses the air in the cuff 310, that is, the air bag.

The pressure sensor unit 320 detects a pressure signal, that is, a blood pressure information signal. The pressure sensor unit 320 is connected to the pneumatic motor 360 and the air passage connected to the air bag of the cuff 310 or between the air storage unit (oxygen cylinder) (not shown) connected to the pneumatic motor 360 and the pneumatic motor 360, respectively.

The blood pressure signal preprocessing unit 330 preprocesses the pressure signal for removing noise from the pressure signal received from the pressure sensor unit 320, that is, the blood pressure information signal, and amplifies the signal. The A / D conversion unit 340 converts the signal into digital And transmits the signal to the blood pressure detection control unit 350.

  The blood pressure detection control unit 350 controls the pneumatic motor 360 and the exhaust valve 370 according to the oscillometric method upon receiving the blood pressure measurement start signal from the calculation processing unit 150 of the main module unit 100, . That is, when the cuff 310 is pressed, the blood pressure detection control unit 350 generates and transmits a motor control signal to the motor driving unit 365, and the motor driving unit 365 drives the pneumatic motor 360 in accordance with the motor control signal So that the air bag of the cuff 310 is pressed. When the cuff 310 is depressurized, the blood pressure detection control unit 350 generates a valve control signal and transmits the valve control signal to the exhaust valve driving unit 375. Accordingly, the exhaust valve 370 is driven so that the air bag of the cuff 310 Decompressed.

The blood pressure detection control unit 350 detects the diastolic blood pressure and the systolic blood pressure from the pressure signal received from the A / D converter 340, that is, the blood pressure information signal by the oscillometric method and outputs the detected blood pressure (that is, To the arithmetic processing unit 150 of the main module unit 100. The arithmetic processing unit 150 of the main module unit 100 is connected to the blood pressure detection memory unit 380, The oscillometric method is a known technique, and a detailed description thereof is omitted here.

3 is a flowchart for explaining a process of detecting a body temperature in the electronic blood pressure apparatus having the noncontact temperature measuring unit of the present invention.

When the power switch of the key input unit 160 is turned on in step S110 and the operation start switch is turned on in step S120, the operation processing unit 150 of the main module unit 100 Transmits a blood pressure measurement start signal to the blood pressure detection control unit 350 of the blood pressure measurement unit 300 and transmits a body temperature measurement start signal to the body temperature detection control unit 250 of the body temperature measurement unit 200.

When the body temperature measurement start signal is received by the body temperature measurement unit 200, the body temperature detection control unit 250 receives the body temperature information signal received through the A / D conversion unit 240 (S130). In some cases, the signal detection step detects the internal temperature of the infrared sensor array (internal temperature of the thermopile array sensor) by the temperature sensor TS provided inside the infrared sensor array (thermopile array sensor) To the body temperature detection control unit 250 of the body temperature measurement unit 200 through the unit.

Here, the body temperature information signal is a signal that is detected by the infrared sensor array unit 210 and passed through the temperature signal preprocessing unit 230 and the A / D conversion unit 240. The body temperature information signal received by the body temperature detection control unit 250 is a thermal image signal and is composed of a plurality of pixels.

In the body temperature information signal calibration step, the body temperature information signal received through the A / D converter 240, that is, each pixel obtained from the infrared sensor array (thermopile array sensor), is calibrated in the body temperature detection memory unit 280 ) Data (S140).

In the ambient temperature receiving step, the ambient temperature preliminarily stored in the body temperature detecting memory unit 280 is read as the ambient temperature, or the internal temperature of the infrared sensor array (internal temperature of the thermopile array sensor) is received from the A / D converter.

In the skin temperature calculation step, the body temperature detection control unit 250 compares the received body temperature information signal with the ambient temperature to calculate the difference value (S160). The difference between the body temperature information signal and the ambient temperature is used as skin temperature Pixels, and only the pixels corresponding to the face portion of the person are selected with a valid pixel (Valid Pixel). Thus, the partial skin temperature of the face is obtained.

In the body temperature computing step, the average skin temperature is obtained by averaging the skin temperature (i.e., the skin temperature of the face portion) of the effective pixels, and the average skin temperature is converted into the body temperature using the body temperature conversion data (S180) Is transmitted to the main module unit 100.

The body temperature conversion data converts the temperature detected by the infrared sensor array according to the difference between the temperature detected by the infrared sensor array and the actual temperature, and the body temperature conversion data may be data given according to the infrared sensor array.

In the body temperature output step, the operation processing unit 150 of the main module unit 100 or the body temperature detection control unit 250 of the body temperature measurement unit 200 compares the body temperature obtained in the body temperature calculation step S180 with a preset reference range (S190). If the body temperature obtained in the body temperature computing step S180 is an abnormal body temperature, the abnormal state is notified through the alarm unit (195), and the body temperature is output through the display unit 120 (S200).

In the body temperature storage step, the operation processing unit 150 of the main module unit 100 stores the received body temperature together with the blood pressure signal detected for each patient (S220).
