Device Description
The valve, non - rebreathing QualityFlow O2 demand valve is a medical device to deliver medical oxygen or a medical air - oxygen mixture to a patient on demand. Unlike continuous oxygen systems, the demand valve only supplies medical gas when the patient inhales, reducing oxygen consumption and ensuring the patient receives gas only when needed.
The demand valve is intended for the following methods of respiratory support:
Method: Demand Valve with Resuscitation Bag:
Function of the Demand Valve: When combined with a resuscitation bag, the demand valve controls the flow of oxygen when the patient is breathing spontaneously. The valve only releases oxygen or air when the patient inhales. The resuscitation bag, can be used to provide manual ventilation in case the patient is unable to breathe on their own.
Application: If the patient is breathing spontaneously, the resuscitation bag remains in standby and can be manually compressed to provide emergency ventilation. Meanwhile, the demand valve automatically supplies oxygen as needed without requiring manual intervention while the patient breathes independently.
Method: Demand Valve with Resuscitation Bag:
Function of the Demand Valve: The mask is placed over the patient's face and connected to the demand valve. The valve delivers oxygen through the mask when the patient inhales and closes during exhalation to prevent gas loss.
Application: This configuration is ideal for patients who are breathing on their own but require supplemental oxygen. The mask ensures a tight seal around the airways, allowing the demand valve to function efficiently. The patient receives only the required amount of gas, minimizing wastage and ensuring higher efficiency.
Three adapter are available for connecting the demand valve to the most common ventilation bags or masks.
Method: Demand Valve and Air - Oxygen Blender:
Function of the Demand Valve: The air-oxygen blender mixes ambient air with oxy-gen to create a specific oxygen concentration (FiO2). This mixture is then delivered to the demand valve, which provides the blended gas to the patient only during inhalation.
Application: The blender ensures that the patient receives an exact oxygen concentration, which is delivered via the demand valve. The demand valve releases the gas only during the patient's inhalation, improving efficiency and reducing gas consumption. This setup is particularly useful in clinical situations where precise oxygen delivery is required.
The QualityFlow O2 demand valve is provided in the following model:
Table 1: Models QualityFlow O2 demand valve
8.9 Technology
The Valve, Non-rebreathing QualityFlow O2 Demand Valve (also known as a non-rebreathing valve) is a specialized airway device used in patients who have difficulty breathing adequately or who require controlled breathing. It is a device that delivers a controlled amount of medical oxygen to the patient based on the patient's breathing needs. The QualityFlow O2 Demand Valve from DEHAS consists of a membrane that is activated by negative pressure during inspiration and a valve mechanism that controls gas flow. During inspiration, the valve opens due to the movement of the membrane, while during expiration it is closed by a return spring.
The function of the demand valve is based on providing gas only when a negative pressure is applied to the membrane, e.g. by the patient inhaling with a connected mask or suction of the resuscitator when connected (expansion after previous compression of the resuscitator). The valve therefore ensures that gas only flows when it is needed.
The demand valve can be in 3 states:
Resting state: When the patient does not inhale, the valve is closed. The return spring holds the diaphragm in a position that closes the exhaust valve.
Inhalation: When the patient inhales, a negative pressure is created. This negative pressure tightens the membrane, which opens the outlet valve and allows gas to flow through.
Exhalation: When exhaling, the pressure acting on the membrane becomes positive, causing the return spring to push the membrane back to its original position and close the exhaust valve. This prevents the gas from flowing further.
The flow of the Valve, Non-rebreathing QualityFlow O2 is pressure controlled.

Response to Changes in the Indications for Use (IFU) Statement
In response to FDA requirements, we have revised the Indications for Use (IFU) statement for the demand valve to ensure clarity and consistency with the predicate device (Spiracle Technology OX - series, HFOC High Flow Oxygen Conserver Model No. 301, K953349). The changes focus on refining the intended use and removing unnecessary limitations to support better understanding and safe use of the device.
Removal of Restrictive Warnings
- Rationale: The original IFU included warnings such as "This device is not a o resuscitator," "This device is not suitable for invasive use on the tube," and "This device should be used solely as an assessor...." These statements have been removed to avoid potential misunderstandings, as the demand valve is designed to provide manual ventilation with a resuscitator bag and non-invasive ventilation for spontaneously breathing patients, similar to the predicate device. By removing these warnings, the IFU now accurately reflects the actual intended use of the device without introducing unnecessary restrictions to its capabilities.
Clarification of Indications for Use (IFU)
- The revised IFU now clearly specifies that the demand valve is intended for the o application of 100% oxygen during manual ventilation with the resuscitator bag,
6
as well as non-invasive ventilation with the resuscitator mask for spontaneously breathing patients. This refined description establishes a clear distinction from invasive ventilation, ensuring that the device's intended use is accurately and consistently described according to FDA requirements and the predicate device.
Retention of Legal Caution Statement
- The legally required statement that restricts the sale of the device to those with o a physician's order ("Federal law restricts this device to sale by or on the order of a physician") remains unchanged to comply with legal requirements and ensure safe use.
Summary These changes ensure that the IFU accurately and clearly defines the demand valve's intended use by removing unnecessary limitations and aligning with FDA requirements and the predicate device.

The Valve, Non-rebreathing QualityFlow O2 Demand Valve (also known as a non-rebreathing valve) is a specialized airway device used in patients who have difficulty breathing adequately or who require controlled breathing. It is a device that delivers a controlled amount of medical oxygen to the patient based on the patient's breathing needs. The QualityFlow O2 Demand Valve from DEHAS consists of a membrane that is activated by negative pressure during inspiration and a valve mechanism that controls gas flow. During inspiration, the valve opens due to the movement of the membrane, while during expiration it is closed by a return spring.
The function of the demand valve is based on providing gas only when a negative pressure is applied to the membrane, e.g. by the patient inhaling with a connected mask or suction of the resuscitator when connected (expansion after previous compression of the resuscitator). The valve therefore ensures that gas only flows when it is needed.
The demand valve can be in 3 states:
Resting state: When the patient does not inhale, the valve is closed. The return spring holds the diaphragm in a position that closes the exhaust valve.
Inhalation: When the patient inhales, a negative pressure is created. This negative pressure tightens the membrane, which opens the outlet valve and allows gas to flow through.
Exhalation: When exhaling, the pressure acting on the membrane becomes positive, causing the return spring to push the membrane back to its original position and close the exhaust valve. This prevents the gas from flowing further.
The flow of the Valve, Non-rebreathing QualityFlow O2 is pressure controlled.

Conclusion:
In all cases the subject device passed or meets the acceptance criteria of general requirements for performance and basic safety. We can find the subject device substantially equivalent to the predicate device SPIRACLE TECHNOLOGY GASEOUS OXY-GEN SUPPLY VALVE (K953349).
There are no differences which raise any different questions of safety and effectiveness.
8.12 Animal testing
No animal testing was performed.
8.13 Clinical tests
The subject of this premarket submission, QualityFlow O2 demand valve, do not require clinical studies to support substantial equivalence.
8.14 Discussion of Differences
There are a few differences between the subject device and the predicate device SPIR-ACLE TECHNOLOGY GASEOUS OXYGEN SUPPLY VALVE (K953349). The differences between the predicate and the subject device are addressed when we compare the subject device to the reference devices. The differences are outlined and discussed in the Substantial equivalence discussion.
8.15 Substantial equivalence conclusion
As outlined in the equivalence discussion, differences of the devices do not raise any questions of effectiveness and safety. Evaluation and performance tests according to the used equivalent standards show, that the subject device passed and meets the acceptance criteria and the performance is better or identical than the predicate device. We can find the subject device substantially equivalent to the predicate device SPIR-ACLE TECHNOLOGY GASEOUS OXYGEN SUPPLY VALVE (K953349).
DEHAS Medical Systems GmbH considers the QualityFlow O2 demand valve to be as safe, as effective, and performance is substantially equivalent to the predicate device SPIRACLE TECHNOLOGY GASEOUS OXYGEN SUPPLY VALVE (K953349).
