Automated External Defibrillator

[INQ. NO. 2108E04] Nanoomtech Co., Ltd., a promising exporter located in Gwangju, Jeonnam, South Korea, has jointly developed an automated external defibrillator (AED) together with the Gwangju Institute of Science and Technology through R&D investment in the medical device sector. The company holds 18 patents related to AED.
Nanoomtech continues to advance into new markets every year and is currently exporting to 30 countries including Japan, Taiwan, and others.
An AED is a medical device used to automatically analyze the heart condition of a patient and help the heart get back to its normal rhythm by giving electric shocks if needed. The use of an AED while performing CPR (cardiopulmonary resuscitation) can increase the survival rate by up to four times. And when it is done within one minute, the rate goes up to 90%.

Automated External Defibrillator

Nanoomtech’s AED is an outstanding procurement product registered with the Public Procurement Service, having a certificate of performance and a designated certificate of outstanding procurement.
Even when it is in a sealed state, the pad condition can be checked as well as the audio guidance functions. In addition, it is able to record the surrounding environment (unique function in Korea) in the event of an emergency accident.
Abnormalities related with the battery, the pad and the service temperature are notified through the LED light and the audio guidance. Thanks to the remote management system (optional), a person in charge is able to check functions and performance of the AED and receive abnormal symptoms through the transmission system for 24 hours.
Anyone can use this device easily and simply just by following the audio guidance. When placing the pad on, it swiftly and accurately performs an automatic analysis of an EGG (electrocardiogram) before informing the user whether or not it would be necessary to deliver electric shocks.

Automated External Defibrillator

You just need to turn on the power and place the pre-connected pad on to use the device. The single pad is suitable for both adults and children. As it is equipped with a periodic self-inspection function, it can be used for emergencies. It is also able to store data on the ECG.
After conducting a periodic self-inspection, the emergency medical device transmits its state through a text message. When the ‘S’ button is pressed, the device checks the states of the device, the battery, the pad and the operational temperature and informs the user accordingly through the audio function. | Blog Magazine of korean electronics, brands and Goods
