No
The device description and principle of operation are purely mechanical, relying on a silicone membrane and pressure differentials. There is no mention of software, algorithms, or data processing that would indicate AI/ML.
No
The device is an accessory to a CPAP or Bilevel Flow Generator and is intended to prevent backflow of oxygen or water, not to treat a condition or disease. Its function is primarily to protect the flow generator, not to directly provide therapy to the patient.
No
The device is an accessory to a CPAP or Bilevel Flow Generator, designed to prevent backflow of oxygen or water. Its function is mechanical (a one-way valve), and it does not gather or interpret data to diagnose a medical condition.
No
The device description clearly describes a physical, mechanical valve with a silicone membrane and outer housing, indicating it is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to prevent backflow of oxygen or water into a CPAP or Bilevel Flow Generator. This is a mechanical function related to the operation of a respiratory therapy device, not a diagnostic test performed on biological samples.
- Device Description: The description details a mechanical valve with a silicone membrane. It describes its function in a patient circuit, not a process for analyzing biological specimens.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in biological samples
- Providing information for diagnosis, monitoring, or screening of diseases or conditions.
- Predicate Devices: The predicate devices listed (Pressure Valve, Full Face Mask) are also not IVDs. They are accessories or components of respiratory therapy systems.
The device's function is purely mechanical and related to the safe operation of a respiratory support system. It does not perform any diagnostic testing.

Device Description
The Oxygen Diverter Valve is an in-line one-way valve that is intended to prevent oxygen or water in the patient circuit from back flowing into a CPAP or Bilevel Flow Generator when the unit is not operating. The Oxygen Diverter Valve incorporates a silicone membrane that seals against the outer housing to vent any backflow to the atmosphere when the pressure drops of the CPAP or Bilevel Flow Generator drops below 2.0cm H20.
The principle of operation is the same as used in the Full Face Mask Anti-asphyxia valve (510(k) number K982530), the difference being in application - in the Full Face Mask, the valve is used to vent CO2 to atmosphere to prevent patient rebreathing.

| Diverter Valve incorporates a silicone membrane that | |
| seals against the outer housing to vent any backflow to | |
| the atmosphere when the pressure drops of the CPAP | |
| or Bilevel Flow Generator drops below 2.0cm H20. | |

| backflow of oxygen or water when the unit is not | |
| operating | |
| Device Technological | The device function is the same as the Pressure Valve |
| (K963250), which is to prevent the backflow of oxygen | |
| or water when the unit is not operating. The Oxygen | |
| Characteristics and | |
| Comparison to | Diverter Valve (ODV) is a simple modification of the |
| Predicate Device(s): | Anti-Asphyxia Valve (AAV) that was FDA cleared as part |
| of the Mirage Full Face Mask 510(k) submission | |
| (K982530). The modification is to reverse the genders of | |
| patient side and flow-generator side connectors to allow | |
| the Oxygen Diverter Valve to be connected, inserted | |
| between the flow generator and the air tube. This valve | |
| is not a medical device in and of itself, but an accessory | |
| to the flow generator system. The Oxygen Diverter | |
| Valve will be used in combination with an existing T- | |

| Performance Data: | Performance testing has been conducted to ensure the |

| Conclusion: | Based upon the discussions above, performance |
