Seizure Emergency SafeSteps NFC

The Seizure Emergency SafeSteps Platform - SafeSteps NFC (near field communication).

Brought to by the Epilepsy + Data Science Lab

What is this?

This keychain is intended for those who care for someone with seizures. If you hold this tag up to a modern smartphone, it will send the phone a link to a website that provides 4 quick reminder messages for what to do at the time of a seizure: 1) nothing in mouth, 2) 5 minutes? call 911 (or country specific code) 3) protect the head 4) lay down on side. The website is here: https://sites.google.com/site/danielgoldenholz/Home/safesteps

Why are these messages important?

1. NOTHING IN MOUTH.There is a myth that you can swallow your tongue and die during a seizure, and therefore people should put something into your mouth to save you. In fact, our lab published a study about this (read paper). This is a foolish myth without factual basis. Indeed, many people do put things into the mouth of people having seizures, and then the patient gets hurt (like breaking a tooth) or swallows something that they might choke on. Putting something in the mouth only ADDS danger. Never do it.
2. 5 MINUTES? CALL 911. Seizures that last longer than 5 minutes are likely to cause brain damage. Time is brain. Most seizure last less than 2 minutes, so if a patient is still convulsing after 5 minutes, they are having a life threatening emergency, and there is no time to do anything except call an ambulance, who likely have life-saving medicine onboard.
3. PROTECT THE HEAD. Patients that have seizures can injury their head. It is easy to move things away from them, cover sharp things with pillows, blankets, clothing or other soft objects.
4. LAY DOWN ON SIDE. Patients sometimes can vomit during or after a seizure. If this happens, they should vomit OUT of their body, rather than IN to their lungs, which can cause aspiration pneumonia.

How should I print this?

The 3MF file is set up to be 2 colors, however feel free to print it in 1 color. Purple is considered the official color for supporting epilepsy, so consider that color.

The important thing for this print is that you need to pause printing partway through to insert the NFC chip.  I used NTAG215 NFC 215 which fit perfectly, and were available from Amazon in bulk. Once the chip is placed inside, complete the print. The 3MF file already has the pause included, but you can change that and do it manually or at a different time - the main point is to pause the print while the inside is open and there is a snug place for the NFC chip to be placed.

Also note: these keychains will be used in hot places (such as left in the car on a hot day). PETG is much more heat stable than PLA - it is recommended to use PETG for SafeSteps.

I printed this at 0.2mm layer height, 15% infill, no brim, and no supports. Probably other settings will work too.

Where can I get NFC chips?

Consider this link https://www.amazon.com/dp/B0DBLRJS4R?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1 , or search the internet.

How do I program the NFC chip?

There are free apps available on mobile devices to do this. On iOS, I used NFC Tools. It takes a few seconds - just hold the chip up to the smartphone when the app is running and set up a “write” with the website. The website to link to the NFC is here:
