Particularly interested in acquiring a defibrillator are first aid providers and relatives of patients belonging to the so-called risk group. However, such devices often have three problems: they are large, heavy and expensive. PocketDefi is small, light and relatively inexpensive.

It weighs 400 grams and is slightly larger in size than a classic can of soda. Under its cover are two electrodes. You won’t have to mess around with any settings anymore – PocketDefi will tell you through the speaker what to do and automatically take care of everything else as soon as you place the electrodes on the victim. Thus, even such a situation will be prevented when, by misunderstanding, you shock a person whose heart has not stopped.

The Heart Foundation also believes that the defibrillator in heart attacks should be as close as possible to the scene of events: “Sudden death due to a heart attack is most often caused by ventricular fibrillation, which can be stopped only by electric shock. Since the electroshock effect must be applied immediately and without loss of precious time, the arrival of ambulance doctors is almost always belated.

PocketDefi is accompanied by an appropriate application. It takes over the control functions via a Bluetooth connection. Push notifications inform you if the device needs to be charged if, for example, it has been lying idle in a bag for a long time. It should – once the company accumulates enough user data – someday work even without communication with the device.

The application can also be used to send a “distress signal”. Even if you don’t have a PocketDefi yourself, you can call for help from those who own a defibrillator and are nearby to (hopefully) rush to your GPS coordinates.

Liimtec, at the time of the launch of the Crowdselling campaign on October 3, requires about 28 thousand rubles for its device. By the release date, scheduled for December 2018, the cost of PocketDefi should increase to 50 thousand rubles. The founder of the company, Jasper Ettema, explains such a long waiting period by the processes of medical certification. The device falls under the category of medical equipment, and therefore more thorough checks will be required.

Mobile phone battery electric shock

In addition, Jasper Ettema told us that this defibrillator does not actually require a monstrous battery, as one would most likely imagine. PocketDefi has a slim 1000 mAh battery that can be recharged inductively. This battery must be reliable enough, because even after 10 years of operation it will be able to perform at least 20 “discharges” – as stated in the instructions.

1000 mAh and more today can be found in almost every smartphone. To our not the most serious question about whether it is possible to repurpose a mobile phone into such a “savior”, Ettema answered: it is not so long to wait for this. The PocketDefi project has its origins in the USB-On-the-Go feature supported by some smartphones and external devices. Thus, it is possible to work, for example, with a printer or a camera, but so far there was no defibrillator on this list. The only problem is standardization and licensing. It’s not easy to put together different operating systems and batteries.

Chip’s opinion: everyone helps everyone

It is no secret that our society is aging. Therefore, it is obvious how important it is to further develop and reduce the cost of first aid. Of course, it would be great if the state developed a system that would facilitate the work of people providing emergency care outside of medical institutions. However, as long as portable Defi is not yet standard equipment, people with heart problems (as well as those who are not aware of their problems in this area) with the widespread use of PocketDefi could feel at least a little safer.
