Abstract

A wearable defibrillation system can establish a local comlink with a mobile communication device, such as a smartphone, tablet-type computer and the like. The mobile communication device can in turn establish a remote comlink with other devices in a network such as the internet. Accordingly, communication tasks relating to the wearable defibrillation system can be performed via the local and the remote comlinks, with or without the participation of the patient, who is wearing the system. The wearer can thus use the familiar interface of a mobile communication device for interacting with his defibrillator system. Moreover, he can do so while keeping on his regular clothes, which could conceal completely the wearable defibrillator system. The patient can thus preserve his dignity and privacy.
