Classified as thermoscan. The present invention changes the structure of the system in the thermoscan and improves the function.

[0003]

The conventional thermoscan measures the temperature in the ear using an electronic temperature-sensitive device, and performs analog / digital (A / D) conversion using a microprocessor (CPU). The body temperature is displayed on an LCD (LCD) to notify the user of the body temperature. However, conventional thermoscans are useful for measuring body temperature, but are not suitable for use in: (1) The visually impaired. The body temperature displayed on the LCD cannot be directly known. (2) Infants. To be afraid of inserting foreign objects into the ear,
I hate thermoscans.

[0004] For this reason, if a voice function is added to the thermoscan, it is possible to notify the measured body temperature by voice or to play music so that infants do not dislike the use of the thermoscan. If an infrared transmission function is further added, the body temperature and heart rate can be transmitted to an external personal computer or microcomputer to record information. In addition, conventional thermoscans are intended to be used only for temperature measurement, and when looking inside the ear, additional lighting equipment is required.If the lighting function is added to the thermoscan, the practicality of the thermoscan will be improved. Can be improved. Thermoscans are widely used in ordinary households and can measure temperature within seconds. If you add more heart rate and other measuring devices,
The added value of thermoscan can be increased.

It is a primary object of the present invention to provide a thermoscan having a communication interface including a voice device and an infrared transmission device. The dual temperature display function using numbers and voice makes it accessible to visually impaired people. In addition, information is transmitted to an external personal computer or microcomputer using an infrared transmission device, and tracking data is stored so that it can be used for home health management.

[0006] Another object is to provide a thermoscan having a heart rate measurement function. Being able to measure heart rate increases the added value of thermoscan.

[0007] Still another object is to provide a thermoscan having an illumination function. The inside of the ear can be seen with the lighting device, thereby increasing the added value of the thermoscan.

[0008]

In order to achieve the above object, the present invention has the following design. Inside the thermoscan main body, one CPU is installed at the center and connected to a temperature-sensitive measurement circuit, an LCD, and a memory having a storage program. Using the temperature-sensitive measurement circuit, measure the infrared heat in the eardrum, digitize the signal with the CPU, compare it with the already corrected data in the memory, check the temperature of the infrared heat, and display the result on the LCD I do. Furthermore, it has the following features.

[0009] The CPU is further connected to a communication interface, which includes a voice chip and an infrared transmitter.

Using a voice chip and a speaker installed in the thermoscan, the temperature is notified by voice at the same time. In addition, the temperature is converted into a communication protocol that can transmit temperature using an infrared transmission device, and transmitted to a microcomputer or personal computer that can communicate with the outside.

[0011] The CPU is connected to a heart rate response measurement circuit to measure the heart rate of the microvessels of the finger. The measured heart rate is notified by LCD or voice. Further, it can be transmitted to an external personal computer or microcomputer through an infrared transmission device.

Further, the CPU is connected to an external lamp driving circuit, and drives a light emitting body installed in the thermoscan main body.
