Iranian Researchers Domestically Produce Automated External Defibrillator
“The AED device revives the patient at the right time until the emergency services arrive and transfer the patient to the hospital,” Ali Haidarnejad, research manager of the knowledge-based company said.
“The AED is an electric charge device that unlike the manual device utilized in hospitals and medical centers detects the need for a defibrillation without the need for a specialist and by analyzing the patient's cardiac rhythm,” he added.
"This device receives the heart signal by connecting two electrode pads on the patient's body. The signal is analyzed by the device in less than 8 seconds and if one of the two rhythms of ventricular fibrillation (V-FIB) or Ventricular tachycardia(V-TACH) is detected, the device will deliver the appropriate joules. The device is designed to be used by two age groups, children and adults, in a way that each of the two groups has its own suitable cable," the company's research manager said.
Joules are the amount of energy an AED delivers in a life-saving shock to the heart of a victim of sudden cardiac arrest.
“In order to make the work easier for the user, this device is designed in a way that it explains all the steps to the user through audio and video instructions. Wherever the user needs to do something, the device explains it well. The device comes out in Farsi and English languages,” Haidarnejad added.
Stating that the domestically-made product does not need to remain switched on always and is only turned on when necessary, he added, "The device does not use electricity and feeds on a reliable battery that can supply the necessary energy to the deliver joule when necessary."
It uses a defibrillation electrode cable, unlike other devices that use electrode pads, which are single-used. "A monitoring cable is used in the defibrillator, which after analyzing the patient's signal and the need to deliver joule sends a message that shock pads need to be connected. This will prevent unnecessary use of the electrode pads device.
The director of the knowledge-based company's research department further said that the battery used by this company is capable of delivering 200 joules with the maximum energy to the patient, adding that its battery pack lasts for at least 5 years and can be used for above 5 years.
Haidarnejad went on to say that the domestic product has all the features of the famous foreign-made products while its price is much lower, about one-third of them.
According to the research director of the knowledge-based company, the device has 5 and 7-inch displays. "An ECG (Electrocardiogram) is also designed for expert users (such as emergency services) to track the patient's heart rate with a high resolution during analysis or resuscitation."
According to company's official, the defibrillator has the capability to connect to the WiFi to send the internal test results to a server.
"Also through a web application, the company is able to monitor all the sold devices so that if a problem occurs such as the failure of any of the boards or the reduction of the battery charge or the death of the battery, the company is notified and gives the necessary warning to the customer," concluded Haidarnejad.
