The BestFit™ Nasal Masks are intended for multiple use on adult patients (body weight >30kg) prescribed with using continuous positive airway pressure (CPAP) or bi-level ventilator system in hospital, clinic and/or home environment.
Device Story
BestFit and BestFit 2 are patient interface nasal masks for adult patients receiving CPAP or Bi-Level positive airway pressure therapy. Masks seal around the nose to deliver pressurized air from a therapy device via a 22mm conical connector. Used in hospitals, clinics, or home environments; operated by patients or healthcare providers. Devices include headgear and are designed for multiple-patient reuse. Masks feature vented designs to facilitate therapy delivery. Healthcare providers use the mask to interface the patient with the ventilator system; effective seal and therapy delivery support patient respiratory treatment. Performance is verified through pressure-flow, dead space, and sound level testing.
Clinical Evidence
Bench testing only. Performance verified via ISO 17510-2 (sleep apnea breathing therapy masks), ISO 10993 (biocompatibility, cytotoxicity, irritation, sensitization), and ISO 5356-1 (conical connectors). Comparative testing against Resmed Ultra Mirage II included pressure-flow curves, dead space, sound levels, and resistance to flow. Packaging integrity tested per ISTA-2A. Cleaning and disinfection protocols validated for multiple-use.
Technological Characteristics
Nasal mask with headgear; 22mm conical connector; vented design. Materials evaluated per ISO 10993. Operating pressure 4-20 cmH2O. Compliant with ISO 17510-2, ISO 10993-1/3/5/6/10, and ISO 5356-1. Multiple sizes available. No software or electronic components.
Indications for Use
Indicated for adult patients (body weight >30kg) prescribed CPAP or bi-level ventilator therapy in hospital, clinic, or home settings.
Regulatory Classification
Identification
A noncontinuous ventilator (intermittent positive pressure breathing-IPPB) is a device intended to deliver intermittently an aerosol to a patient's lungs or to assist a patient's breathing.
