The Dual Band Chin Strap by Knightsbridge Sleep Solutions features a revolutionary two-strap system:
Non-elastic strap (blue): Prevents the jaw from lowering.
Elastic strap (black/white): Provides a gentle, supportive upward force.
Together, these straps create a compound force curve—as shown in the graph—where minimal pressure is needed to keep the jaw comfortably closed. The elastic band offers gentle lift, while the non-elastic band engages only when the mouth begins to open, ensuring comfort at rest and effective support during sleep.
This unique design results in exceptionally low leakage and improved CPAP performance compared to using a mask alone.
Clinical Test Results:
Full Face Mask without Chin Strap → Acceptable AHI, but high leakage (up to 40% of the night).
Nasal Mask without Chin Strap → Low AHI, but still significant leakage (18% of the night).
Nasal Mask with Dual Band Chin Strap → Very low AHI with no leakage.
Full Face Mask with Dual Band Chin Strap → Low AHI with no leakage.
