MATERIALS & COMPOSITION

Material composition and physical tolerance of the instruments

Medical-grade silicone

Flexible, hypoallergenic material used in the anatomical mouthpiece.

Thermoplastic polycarbonate

Outer structure resistant to light impacts and continuous wear.

Precision elastomer

Flexible membrane responsible for sealing the one-way valve.

Grade 304 stainless steel

Return spring protected against corrosion caused by condensation.

Inert materials for daily respiratory use

Every component has been selected for mechanical strength, hygienic stability, and zero particle shedding.

Contact body Platinum-cured polymer free of petroleum-derived plasticizers

Technical medical-grade silicone

Allows for a comfortable dental grip without permanent deformation during intense exertion.

✓ Pre-dispatch inspection

Chassis and dial Food-grade technical thermoplastic with a rigid structure

High-density polycarbonate

Maintains a constant chamber diameter through changing ambient temperatures.

✓ Pre-dispatch inspection

One-way valve Synthetic elastomer resistant to constant moisture and saliva

Elastomeric sealing membrane

Ensures the expulsion of exhaled air outward with no added resistance.

✓ Pre-dispatch inspection

Adaptation protocol for respiratory exertion

Progressive sequence to coordinate diaphragmatic work with stride mechanics during an easy run.

01

Static adjustment at rest

Select the minimum resistance level while seated to become familiar with the lip seal and diaphragmatic activation.

02

Walking and easy running

Transfer the routine to a light jog while maintaining a constant ratio of two steps per inhalation and two per exhalation.

03

Medium resistance consolidation

After three weeks of regular practice, increase resistance by one point to reinforce ventilatory pattern control.
