DefiSign LIFE AED Fully-Automatic

User-friendly AED for every rescuer

This AED starts automatically as soon as the lid is opened. Clear spoken instructions and LED-supported graphics guide the rescuer through the resuscitation process step by step. Electrodes are immediately visible and pre-attached in the AED, saving precious seconds during an emergency.

This AED is suitable for:

• Shops and office spaces
• Sports facilities and swimming pools
• (International) companies
• Holiday parks and railway stations

Fully automatic operation

This AED administers the shock fully automatically, without user intervention. Once the electrodes are applied, the device independently analyses the heart rhythm and automatically administers a shock if necessary, without the need to press a button. Are you looking for an AED with fully automatic operation? Then this variant of the DefiSign LIFE is a good choice!

Intelligent monitoring of electrodes

The DefiSign LIFE itself monitors the shelf life of electrodes. The device automatically gives a notification when the electrodes need to be replaced. Regular electrodes have a lifespan of about 3 years.

DefiSign LIFE with paediatric electrodes

For paediatric resuscitation, special paediatric electrodes can be used, which are kept at the back of the AED. When using these electrodes, the device automatically adjusts the energy level for the smaller body. The children's electrodes last for about 2 years.

Multilingual support during CPR

Switch between English, Polish and German at the touch of a button - even during CPR. Other language combinations are available on request.

Durable Swiss quality

With a 10-year warranty period, you are assured of a reliable device. The internal battery lasts 10 years and the regular battery has a lifespan of approximately 5 to 6 years, depending on usage. The AED’s service indicator light shows when the main battery needs to be replaced or when the internal battery requires an update.

What does the Medisol product specialist say?

“This AED is indeed very easy to operate. It is actually so simple that it is difficult to do anything wrong. I find the purchase price remarkably reasonable, especially when I look at the many options the device offers. Examples include the multiple installed languages and the ability to switch between them at any time. It is also a definite advantage that this AED indicates itself when the electrodes need to be replaced. From experience, I know that some people prefer not to operate an AED with a lid. In this case, I must say that this has also been carefully considered. Even if the lid were to close during an emergency, the AED will continue to operate as long as the electrodes remain connected. A fantastic product improvement since the end of 2025 is the extension of the internal battery lifespan from 6 to 10 years.”
