Family-Developed Night Time Seizure Detector [video]


Managing epilepsy can be challenging, particularly at night when seizures that lack movement and sound are not detected by usual monitoring devices. Especially when one is a caregiver for a child with epilepsy, the very real concern about Sudden Unepected Death from Epilepsy (SUDEP) can result in sleepless nights.

A family in England whose son has Dravet Syndrome, a severe form of epilepsy, used a motion detector under their son’s mattress and motion detecting cameras as well as a sound-sensing system, but found they still missed some seizures when there was no movement; any vocalization was undetected because their son’s head was buried in pillows. Driven by their concerns about the possibility of SUDEP as well as a need for better sleep themselves, the Perry’s developed PulseGuard, sold by their not-for-profit company, Ardis Technologies (currently available in the U.K. only.)

PulseGuard consists of a heart rate sensor band and an iPAD. The band can be worn on the wrist or ankle. The band communicates via Bluetooth to a dedicated iPAD that runs a monitoring app in which you can set minimum and maximum heart rate detection parameters. The iPAD has to be in the same room as the PulseGuard sensor band, but it can be paired via Bluetooth with speakers located in a caregiver’s room so when needed, an alarm can be sounded so the caregiver can provide needed assistance. The company is careful to point out that the PulseGuard is not a medical device and does not prevent or treat epilepsy; the sole purpose is to provide nighttime heart rate monitoring.

We’ve looked at other Health Tech developments for epilepsy such a the SmartWatch that detects shaking and Bioserenity, a combination shirt and cap embedded with multiple sensors to continuously gather biometric data. PulseGuard is designed to work specifically when there is no movement and has a simple band design.

AMA Launches Healthcare Innovation Company

Contemporary Office Table with Equipments and Chairs

Startups are lean, nimble, and innovative. Large established organizations tend to be slow to change and the process of making a decision can take a painfully long time to work its way through all the required channels. As a result, it is newsworthy that the American Medical Association (AMA) — an old and large organization — […]

Citizen Response to Cardiac Events [video]

Pulsepoint with video 600x271

Sudden cardiac arrest (SCA) is a major killer in the U.S., accounting for approximately 325,000 deaths per year, or nearly 1,000 a day. SCA is not the same as a heart attack, although SCA may result from a heart attack. When such a cardiac event occurs response time is the most significant factor for survival. […]

Eye Implant Helps the Blind See Again

retinal implant

Implanted digital devices have to be the ultimate in “wearables;” they effectively become part of your body. Some digital implants are almost commonplace, such as the cochlear implants that can help the deaf hear again. One field in this area that has seen rapid advances is that of sub-retinal implants that can help the blind […]

Big Data Meets Personal Protection with Virtual Reality Mask

Frog Airwaves Mask 600x271

Global air quality affects us all, but clearly people living in some areas have it much worse than most. Health Tech potentially meets air quality on two fronts: personal protection for individuals and air quality monitoring for the population at large. The international design firm Frog Design, Inc.’s Shanghai studio is developing a concept for […]

The range of sensors used in Health Tech continues to broaden in the rapidly expanding Internet of Things. We already know measuring various elements in blood and reading electrical waves can tell a lot about individual health, but while still vital, those are old school signs of relative health. Recently we looked at measuring fat […]

Phone App Aims to Train Safer Drivers

CDC car accident data

As the illustration above from the Centers for Disease Control and Prevention (CDC), car crashes take an enormous toll in this country each year. More than 37,000 people die each year from car crashes, with another 2.3 million suffering injuries. By any measure, this can be viewed as a healthcare crisis. One company is trying […]

Your Chance to Help With Epilepsy Research

EpiWatch 600x277

Health Tech is one of the leading areas of Internet of Things development. Most of the research takes place in private research and development labs, universities, or groups made up of both schools and commercial companies. Typically anyone not actively involved in ongoing development has no role other than to potentially read press releases or […]

Computer Chip Runs on Body’s Energy

Molecular Dreams series. Artistic abstraction composed of conceptual atoms molecules and fractal elements on the subject of biology chemistry technology science and education

Adenosine triphosphate: you might recognize this chemical compound from your high school or college biology class, or perhaps its acronym ATP will ring a bell. The bottom line is that you can’t live without it. This is the molecule that takes energy from where it is generated (by metabolizing food) and delivers it to the […]
