#### Device Description

The Oran Park Mask is an accessory to deliver air flow and positive air pressure generated by positive airway pressure (PAP) devices such as CPAP or bi-level flow generator systems to the patient's airway, for the treatment of Obstructive Sleep Apnea (OSA) or ventilator support (non-life support). It delivers the treatment pressure from the source device to the patient's upper airway by providing an air seal between the PAP device and under the patient's nose and mouth.

There are 2 variants to the Oran Park Mask:

- . Oran Park Mask (Home Use) Intended for single patient re-use (SPMU) for home use. It is configured with a diffused venting port located on the elbow, known as the QuietAir elbow.
- . Oran Park SLM (Sleep Lab Mask)

Intended for multi-patient re-use (MPMU) and must be reprocessed if reused between patients. It is configured with a non-diffused venting port located on the elbow, known as the Multihole elbow.

The Oran Park mask comprises of 4 sub-assemblies: headgear, frame, cushion and elbow. The venting ports and anti-asphyxia valve are incorporated into the elbow assembly. There are four magnets incorporated in the Oran Park mask – two magnets in the frame assembly and 2 magnets in the lower headgear clips – with a magnetic field strength up to 400 mT. The mask help facilitate attaching and detaching the headgear to the mask frame when regularly fitting the mask for use. The cushion and headgear are available in various sizes to fit a wide patient population. Soft wraps, which are attached to the Oran Park mask frame, are available as an optional accessory for patient's comfort.

The Oran Park mask is a prescription device and is supplied non-sterile.

#### Indication For Use

The Oran Park full face mask is intended for use in the home or hospital/institutional environment on patients weighing more than 66lb (30kg), who have been prescribed non-invasive CPAP or bi-level positive airway pressure (PAP) therapy.

Only the Sleep Lab Mask (SLM) variant is intended and validated for multi-patient reuse and must be reprocessed if reused between patients.

### Similarities and differences with the predicate device

The subject Oran Park Mask and the previously cleared predicate AirFit F20 (K153563) devices share the same technological characteristics and principle of operation. They act as a patient interface seal to deliver treatment pressure generated from a positive airway pressure (PAP) device to the patient's airway.

The subject and predicate device have equivalent intended use and the following similarities:

- A silicone elastomer cushion to achieve air seal at the patient's mouth and nose.
- The cushion is held in place via the mask frame.
- The frame is strapped to the patient's head and sits along the sides of the face, held in place via headgear.
- An elbow assembly connects to the PAP device tubing.
- . Venting ports/AAV flush out CO2.
- The mask can be disassembled for cleaning and reprocessing in accordance with the labelling.
- A port compliant to ISO 5356-1 is used to connect to the PAP delivery hose.
- . Polymeric materials are used for the construction of the pneumatic and structural components.
- . Foam padded fabric materials are used for the construction of the head straps.
- . Multiple cushion sizes are available to allow for adequate mask fit over the intended patient population.
- . Similar performance i.e., both masks have similar operating pressure range and pressure flow characteristics.
- Same operating environments i.e., re-use in the home and hospital/institution environment.

The main difference between the subject Oran Park Mask and the predicate AirFit F20 device (K153563) ાંડ:

- Mask component design and geometry
- Different operating ResMed flow generator settings i.e., "Full Face Mask" vs "Pillows"
- Incorporation of new materials for Headgear laminate and elbow assembly vent ring
- Reprocessing claims

These differences do not affect the substantial equivalence claim to the predicate device because nonclinical testing demonstrated that the new device has equivalent performance to and is as safe as the predicate device.

#### Non-clinical data submitted

Non-clinical verification and validation testing completed for the new device demonstrated that the Oran Park Mask met all intended performance requirements. These included:

Applicable performance and safety tests in accordance with ISO 17510:2015 Medical devices – Sleep apnoea breathing therapy – Masks and application accessories:

- CO2 rebreathing
- Pressure-Flow characteristics
- Resistance to flow
- Anti-Asphyxia valve operating pressures
- Breathing resistance (single fault)
- Through impedance
- . Inadvertent anti-asphyxia valve operation

Other Bench tests:

- . Mechanical Integrity of the mask system before and after the following environmental tests:
- Home cleaning .
- Transportation and storage
- Operation environment
- l Free fall

Biocompatibility evaluation was conducted in accordance with ISO 10993-1, ISO 10993-10, ISO 10993-12, ISO 10993-17, ISO 10993-18 and ISO 18562 on components that had patient exposure classifications of permanent external communicating device (tissue) and /or permanent skin contact.

Validation of reprocessing claims included a combination of cleaning efficacy, disinfection efficacy, residual toxicity, and mechanical integrity testing.

Verification confirmed that the new device met the predetermined acceptance criteria, and the performance is substantially equivalent to the previously cleared predicate AirFit F20 (K153563).

Oran Park Mask System was designed and tested in accordance with the applicable requirements in relevant FDA consensus standards including:
