Description

Body temperature logging patch {BODY TEMPERATURE LOGGING PATCH}

The present invention relates to a body temperature logging patch attached to the body to measure and collect body temperature in real time, and more specifically, an attachment that allows easy and convenient real-time measurement and confirmation of body temperature through linkage with an app of a smartphone. It relates to an electronic thermometer.

In general, thermometers are classified into contact and non-contact, and are classified into mercury thermometers, infrared thermometers, crystal thermometers, thermocouple thermometers, and thermistor thermometers according to the principle or medium of measuring body temperature.

The body temperature measured using such a thermometer is the most basic human information for checking the occurrence of abnormalities or diseases, infection, worsening of diseases, and health status, and accuracy and promptness of notification are very important for the measured body temperature value. .

In particular, the increase in body temperature of infants with low immunity is likely to occur in the process of removing the virus that has invaded into the body, and an emergency situation or sequelae may be left, so periodic measurement and confirmation are required.

Recently, research on active medical technology that combines medical devices and IT devices such as smartphones has been actively conducted. As part of this, a temperature sensor that measures body temperature and a patch-type body temperature measuring device with a built-in battery and wireless communication module are attached to the armpit to measure body temperature in real time, and it is linked with a smartphone app through a wireless signal such as Bluetooth. A technology that can check and monitor a patient's body temperature in real time is known.

For example, in Korean Patent Application Publication No. 10-2019-0010219, there is a'body temperature measuring device' that can flexibly bend and attach in response to a user's bent or bent body part, such as infants, and naturally bends according to the user's movement. It is disclosed. As shown in Fig. 1, a cover part 10 with a lower surface attached to the skin of infants and toddlers, a sensor part 20 built into the cover part 10 and measuring body temperature to generate a temperature value, and the sensor It is composed of a flexible circuit board 30 on which a communication device for wirelessly transmitting the temperature value received from the unit 20 is mounted, and a battery 50 that supplies power to the flexible circuit board 30.

However, a body temperature measuring device according to such a conventional technology only measures body temperature in real time, and it is a structure that interlocks with a smartphone app through a wireless signal using Bluetooth, Beacon, and NFC (NFC). There is a limitation in not being able to quickly respond to emergency situations such as when the power of the smartphone is turned off, during a call, or when carrying a smartphone and going out, the body temperature of infants and toddlers rises above 40℃ and shows symptoms of high fever.

In addition, due to the nature of the cover part 10 made of a highly hydrophobic silicone material, it does not have a function of absorbing moisture such as sweat, and thus, when the temperature or humidity is high, the contact feeling is poor, causing discomfort and foreign body sensation. have.

On the other hand, silicone has long been in the spotlight as a medical material due to its excellent physical properties, precise moldability, and light weight. However, since silicone has adhesiveness on the surface, it provides a living environment for various pathogenic microorganisms and can cause odor and various diseases.

Accordingly, it is necessary to meet the prerequisite that the silicone for a body temperature measuring device must have good antimicrobial properties and absorbency while maintaining flexibility that is elastically deformed according to bending when attached to the user's skin.

It should be noted that it does not mean a technique widely known in the field, and in addition, reference numerals in the prior art are mutually independent of reference numerals in the present invention.

For example, a medical liquid silicone first liquid and a second liquid are weighed at 50:50, and 5 wt% of a super absorbent polymer that absorbs moisture and maintains the state is added thereto, mixing for 5 minutes, and then vacuum degassing. After injecting into the mold coated with the silicone release agent and curing in an oven (hot air dryer) at 120~140℃ for 10 minutes, the surface of the upper housing 11 is first formed, and then the first and second liquids of medical liquid silicone are added to 50 It can be manufactured by weighing 50 and injecting it into a mold to form the back side of the upper housing 11 secondarily.

In addition, an antimicrobial layer may be formed by depositing a photocatalyst comprising hydroxyapatite, titanium dioxide (TiO ₂₎ and germanium (Ge) in the same ratio on the surface of the upper housing 11.

For example, after preparing a target material to be deposited with hydroxyapatite, titanium dioxide (TiO _2), and germanium (Ge), it is formed on the surface of the upper housing 11 by an ion beam assisted electron beam deposition method ( IBAD) can be used to improve the adhesion and density of the antimicrobial layer.

That is, oxygen gas (O ₂ gas (P = 10 ^-) after lowering the vacuum level of the vacuum chamber to 10 ^-7 Torr using cryopump (OB-10, Helix Technology, Mansfield, MA, USA) After pre-etching the surface of the upper housing 11 with ⁴ Torr)), a target material may be deposited so that the deposition rate is 10 Å/sec.

In this process, the adhesion can be improved by assisting the deposition with argon ions, and even after deposition is completed, the coating layer can be strengthened by post-treatment with argon ions for 10 minutes. have.

At this time, the intensity of the electron beam (Telemark, Fremont, CA, USA) is from 8.5kV to about 0.1A/120V, the thickness of the coating layer to be deposited is 10,000Å, and the substrate is in a vacuum chamber. The rotation speed of can be set to 75rpm.

The sensor 20 measures body temperature and outputs an electrical signal, and is installed in the housing 10 while being mounted on the flexible circuit board 30.

Further, the lower portion of the sensor 20 is exposed to the outside through the sensor hole 19 of the lower housing 12 in order to directly contact the user's human body.

Here, as the sensor 20, a temperature sensor of a method of measuring body temperature through contact with a human body may be adopted and applied. For example, it can be implemented as a resistance temperature sensor or a thermistor using the principle and characteristic that the resistance value changes according to temperature, and in the case of an analog type, body temperature information is converted to digital by adding a circuit for digitalization and then output as an electrical signal. I can.

The flexible circuit board 30 is equipped with a communication device that wirelessly transmits the electric signal of the sensor 20 for interworking with an app of a smartphone, and a battery 31 that supplies power is mounted on the housing 10 ) Is built in.

In addition, on the flexible circuit board 30, an LED light emitting device 32 that flashes when the measured temperature value of the sensor 20 is out of the set temperature range is mounted, and the sensor 20 and the LED light emitting device 32 operate. A button switch 33 for turning on/off the power is mounted.

That is, the control circuit on the flexible circuit board 30 is driven according to the on/off operation of the button switch 33, and according to the control, the battery 31 is connected to the sensor 20, the communication device, and the LED light emitting device 32.
