DIY Oxygen Inhalator by AnuragRana
by Thingiverse
Last crawled date: 3 years, 1 month ago
This is a DIY (do it yourself) inhalator concept.
During the COVID19 surge, an enhanced need for oxygen therapy has been required.
While people are able to manage oxygen cylinders, the inhalator needed to utilise the oxygen is in short supply.
This concept realises an inhalator from the oxygen cylinder to patient's mouth with:-
• A small length of RO (reverse osmosis) tubing and 2 No RO elbows (standard size, 1/4th inch British Standard Pipe (BSP). Optional, a flow valve of RO type.
• A normal coke bottle (Note: coke/pepsi/sprite bottles.. any soft drink bottle. Mineral water bottles have a different neck screw, and this design will not be air tight) that acts as a humidifier.
• If you don't have a nasal cannula, then another coke bottle that can be cut to make a small breathing mask.
• And most importantly, 3d printed parts here that make the adapters to connect between different sizes of oxygen cylinder, coke bottle, and the cannula/mask.
The important 3d printed parts are:-
• Oxygen Cylinder to 1/4" RO (quarter inch BSP) elbow connector
• 1/4" RO to coke bottle
• 1/4" RO to coke bottle, with an out-flow for nasal cannula.
There are various configurations possible, e.g
Direct cylinder to nasal cannula (note: cannula fits directly on RO pipe)
Direct cylinder to nasal cannula with a valve
Cylinder to a humidifier bottle and then to a cannula
in case cannula not available, cut a coke bottle at about 45 degree slant, and then use a 3d printed 1/4" RO cap to connect it to a tubing, Or the output of a humidifier bottle.
Most joints are sufficiently air-tight, but it is recommended to use plumbers tape (teflon tape) to further seal joints to prevent small losses of precious oxygen.
Please refer images showing various configurations, parts and setups etc.
Good luck to everyone involved.
