A handheld breathing trainer built around a 3-stage resistance insert. Interchangeable orifice cartridges give three calibrated resistance levels.

Design highlights

• Cartridge orifices sized and verified across the three resistance stages.
• Two-part housing with a quarter-turn interface: no tools needed for cleaning, no small parts to lose.
• Material choices constrained to skin-safe, washable polymers.
• Designed for low-cost assembly: every part self-locates, no fasteners.

Outcome

Functional prototypes validated the resistance curve of each stage; the design is ready for small-batch production.
