Intended Use
The INOmax DS delivery system delivers INOmax® (nitric oxide of inhalation) therapy gas into the inspiratory limb of the patient breathing circuit in a way that provides a constant concentration of nitric oxide (NO), as set by the user, to the patient throughout the inspired breath. It uses a specially designed injector module, which enables tracking of the ventilator wayeforms and the delivery of a synchronized and proportional dose of NO. It may be used with most ventilators. The INOmax DS provides continuous integrated monitoring of inspired O2, NO2, and NO, and a comprehensive alarm system. The INOmax DS incorporates a battery that provides up to 6 hours of uninterrupted NO delivery in the absence of an external power source. The INOmax DS includes a backup NO delivery capability that provides a fixed flow of 250 mL/min of NO which along with user supplied 10 L/min of oxygen provides 20 ppm in the gas flow to a patients breathing circuit. It may also use the INOblender for backup. The target patient population is controlled by the drug labeling for INOmax and is currently neonates. The primary targeted clinical setting is the Neonatal Intensive Care Unit (NICU) and secondary targeted clinical setting is the transport of neonates.
Device Description
The INOmax DS provides a constant dose of INOmax (nitric oxide) therapy gas into the inspiratory limb of the ventilator circuit. The INOmax DS uses a "dual-channel" design to ensure the safe delivery of INOmax. The first channel has the delivery CPU, the flow controller and the injector module to ensure the accurate delivery of NO. The second channel is the monitoring system, which includes a separate monitor CPU, the gas cells (NO, NO2, and O2 cells) and the user interface including the display and alarms. The dual-channel approach to delivery and monitoring permits INOmax delivery independent of monitoring but also allows the monitoring system to shutdown INOmax delivery if it detects a fault in the delivery system such that the NO concentration could become greater than 100 ppm. INOmax drug is stored as a gas mixture of NO/N2 in an aluminum cylinder at a nominal pressure of 2200 psig. The cylinder is attached to a high pressure regulator which incorporates a pressure gauge that indicates cylinder pressure when the cylinder valve is open. The cylinder regulator is attached via tubing to the INOmax DS using one of the two NO/N2 quick connect inlets on the back of the machine. The INOmax enters the back of the INOmax DS, passes through a filter. then a safety shutoff valve, which is open under normal operation. An injector module is placed in the ventilator gas flow between the ventilator inspiratory outlet and the humidifier. Based on the ventilator flow, the INOmax cylinder concentration and set INOmax dose, the proportional solenoid delivers INOmax into the ventilator circuit via the injector module. This allows the INOmax DS to deliver a constant dose of INOmax regardless of the ventilator flow pattern or breath rate. A flow sensor inside the INOmax DS also monitors the NO flow out of the machine. A check valve is included prior to the INOmax DS drug outlet to prevent pressure effects from the ventilator breathing circuit interfering with the NO flow sensor reading. The INOmax DS gas monitoring system provides monitored values for inspired NO, NO2, and O2. The sample gas is withdrawn form the breathing circuit and goes through a water trap to remove excess water, a zero valve, a sample pump and finally a sample flow sensor to the gas monitoring cells. The zero valve allows the gas cells to be zeroed (during low calibration) without having to disconnect the sample line from the breathing circuit. The pump and sample flow sensor ensure a constant sample gas flow rate is maintained to the monitoring cells. The gas monitoring cells are electrochemical; they are specific to each gas and provide an electronic signal, which is proportional to the concentration of the gas present. If the delivery system does go into shut down, the INOmax DS has an integrated backup function which provides a fixed flow of INOmax (0.25L/min) into the injector module using a pneumatic on/off switch and a restrictor built into the delivery side of the system. This fixed flow of INOmax will provide 20 ppm of NO when the continuous ventilator gas flow is 10 L/min. The backup is only for short term use until a replacement delivery system can be obtained. An alarm will warn the user if the backup system is turned on while the main delivery system is in use for INOmax delivery.
More Information

No
The description focuses on hardware components, control systems based on ventilator waveforms and user settings, and safety mechanisms. There is no mention of learning, adaptation, or complex pattern recognition characteristic of AI/ML.

Yes
The device delivers INOmax (nitric oxide) therapy gas, which is a treatment for patients.

No

This device is designed to deliver therapy gas and monitor the delivered gas levels (O2, NO2, NO) to ensure safe and effective delivery of the treatment. It does not perform a diagnostic function to identify or characterize a disease or condition.

No

The device description clearly outlines numerous hardware components including a delivery CPU, flow controller, injector module, monitoring system with a separate monitor CPU, gas cells, user interface with display and alarms, battery, high pressure regulator, tubing, quick connect inlets, filter, safety shutoff valve, proportional solenoid, flow sensor, check valve, water trap, zero valve, sample pump, sample flow sensor, electrochemical gas monitoring cells, pneumatic on/off switch, and restrictor. This is not a software-only device.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The INOmax DS delivery system delivers a therapeutic gas (nitric oxide) into the patient's breathing circuit. It also monitors gases within the breathing circuit (inspired O2, NO2, and NO).
  • No Sample Analysis: The device does not analyze samples taken from the patient's body. Its monitoring function is focused on the gas composition being delivered and inhaled, not on biological samples.

Therefore, the INOmax DS is a therapeutic and monitoring device used in the delivery of a drug, not an in vitro diagnostic device.

Dear Mr. Montgomery:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
