Telemedicine offers patients the chance to meet with a doctor, 24/7, without leaving home. But many physicians are wary of participating because they can’t peer into patients’ ears, look down their throats or listen to their lungs remotely.
A new genre of home diagnostic devices aims to address those concerns by giving patients some of the same tools that doctors use during in-office exams. Think part Star Trek Tricorder, part Harry Potter Extendable Ear.
The closest to market is Tyto, a hand-held gizmo about the size of a softball. One attachment works like a stethoscope to capture and record a patient’s heartbeat and breath sounds. Other attachments allow a built-in camera to get a good look at patient’s tonsils and into the ear canal. The camera can also take high-resolution photos of skin lesions, rashes and moles. All the images, sounds and readouts can be shared with a doctor over the internet in real time or stored in a software program for later use.
