Development of a Wearable Diagnostic and Therapeutic Device for Hypo and Hyperthermic Patients

Hypothermia and hyperthermia are body temperature related issues. Abnormal high body temperature is known as hyperthermia and if body is too cold it is hypothermia. These problems are encountered when a person is exposed to either very high or very low temperature. People exposed to extreme temperatures may suffer from heat strokes and dehydration. If this problem is not treated, it leads to severe effect even to death. So, this type of defect should be detected well in advance to take necessary precautions to minimize the impact. In this paper a smart jacket in which a Peltier module is placed inside the jacket for hyperthermic and hypothermic patients is proposed. A smart watch is used for diagnosis purpose and jacket is used as therapeutic purpose. The DS18B20 temperature sensor used to detect the body temperature using wrist watch. MAX30102 pulse rate sensor and DHT11 humidity sensors are also used. These sensors are connected to Arduino Nano microcontroller which takes sensor inputs and controls the temperature. If the patient's body temperature is lower than the normal temperature, then the smart watch sends signals through GSM module transmitter to the receiver in the jacket. Using Peltier effect, the jacket produces warmness/coldness. The first aid is given to the patient through the application of heat/cold.
