Portable trach/vent humidifier

A big complaint for most people with a trach/ventilator (me included) is dry air. This is typically solved with humidifiers that create vapor by heating distilled water on what is essentially a hot plate. However these require an AC electrical outlet which ELECTRIC wheelchairs don't have (it's asinine, I know). The other way is with HME's which trap residual vapor in what is basically a piece of foam. This is not effective IMO.

I came up with a portable third option! It mounts a standard Fisher & Paykel Heated Humidifier Chamber like this:

To a coffee mug warmer. I designed mine around this one specifically:

It's powered by a 155wh external battery with a 110/120 volt AC outlet, like this:

I also used a stainless steel quick release pin, diameter 1/4", usable length 1-1/2", overall length 2" like this:

…to hold the top half to the bottom. 

Keep in mind the mug warmer uses 20w. Given that the battery is 155wh, you'll theoretically get around 7 hours of run time. 

Directions:
After printing place the mug warmer in the base, place the lid around the chamber and then slide the lid & chamber over the humidifier until it slots into the back of the base. Finally place the quick release pin through the lid and base.

Warnings:

• If the wheelchair flips over or tilts/leans back all the way water could theoretically get into the hose. Use only on level surfaces and in the company of a caregiver or nurse.

*I take no responsibility for damaged equipment or physical harm due to user error or failure to follow these guidelines*

Print with something that can withstand higher temperatures like PETG, ABS or PC. I used Hatchbox PETG.
