Description

[0001] The present invention relates to an ear-type bio-

 The present invention relates to a measuring device for allowing a user to easily confirm information on a living body signal acquired by being inserted into an ear. More specifically, the present invention relates to a measuring device for transmitting change information of a living body signal, And to provide information to enable the user to act according to the situation. The device measures the temperature of the eardrum accurately by measuring the biomedical information of both sides of the ear canal. And a ventilation hole for suppressing a sound and a temperature rise by inserting the ear into the ear. In order to minimize the inconvenience due to skin contact and pressure, the skin is treated with silicone It is convenient to be able to wear for a long time.

 The bio-signal is an important indicator that informs the health condition of the individual. Since the signal changes according to the surrounding environment and the health state in daily life, it is not affected by the spatial and temporal constraints, The system that can check and feedback from time to time is attracting attention. (Schrenker R. A. Software Engineering for Future Healthcare and Clinical Systems, IEEE Computer Society, 2006, 39: 26-32.)

 The body temperature, pulse, oxygen saturation, and blood pressure are signals that can be measured in the ear as a bio-signal. The body temperature is an index reflecting the evaluation of the state of health, the presence or absence of disease, and the progress of the body. Non- , And a method to measure in the forehead and the forehead. The method that best reflects the deep body temperature is a method of measuring the temperature of the eardrum supplied with the blood flow of the internal carotid artery such as the hypothalamus, which is the body temperature control center. (Shiraki, K., Konda, N., & Sagawa, S. Esophageal and tympanic temperature responses to core blood temperature changes during hyperthermia. Journal of Applied Physiology, 1986, 61: 98-102.)

 When measuring the tympanic temperature, the angle of bending of the device considering normal twist of the ear canal should be taken into consideration, and measurement should be made by pulling adults upward and children downward. (Pransky, S. The impact of technique and conditions of the tympanic membrane upon infrared tympanic thermometry. Clinical Pediatrics, 1991, 30 (4): 50-52.)

 Pulse, blood pressure, and oxygen saturation are important indicators of cardiopulmonary capacity of the individual. Pulse and oxygen saturation are mainly used by photoelectron pulse waves using extinction coefficient. (Nijoer J. A., Dorlas J. C., & Mahieu H. F. Photoelectric plethysmography, Fundamentals of SoFthereflection and Transmission Methods, Clin. Phys. Physiol., 1981, 2 (3): 205-15.)

 Measurement of blood pressure was mainly based on measurement using cuff pressure and arterial pressure. Recently, blood pressure measurement method using pulse wave transmission time has been devised. (Allen J. Photoplethysmography and its application in clinical physiological measurement. Physiol Meas 2007, 28 (3): R1-39.)

 Biofeedback is a "biological feedback" that can be used to measure various phenomena occurring in the human body and convert them into visual, auditory, and tactile information, Method.

 Recently, various external devices that can be connected to smart devices have been widely used due to the recent development of technology, and external devices that visually show various vital signals such as pulse, blood pressure, and body temperature through the smart device are being developed.

 Among the instruments measuring the body temperature, there is a problem in that the measuring instrument inserted into the ear does not produce a normal result according to the inserting method and direction, and a problem that the sound is not heard due to the sealing of the ear for a long time, . (Craig, J. V., Lancaster, G. A., Taylor, S., Williamson, P. R., & Smyth, R. L. Infrared ear thermometry compared with rectal thermometry in children: A systematic review. Lancet, 2002, 360, 603-609.

 In addition, since the apparatus for measuring blood pressure, pulse, and oxygen saturation of the bio-signal measuring apparatus is bulky, it is difficult to periodically measure the portability and it is necessary to measure it after worn on the wrist and upper arm. Therefore, There is a problem that it is not an appropriate site for measurement.

 Therefore, by devising a bio-signal measurement device that combines body temperature, blood pressure, pulse, and oxygen saturation that can be measured in the ear, it fixes the problems of existing measurement devices and works with the smart device to periodically measure and bio- And to develop a measuring instrument that can perform health care by detecting the change of temperature.
