Intended Use
The ViaNOx Delivery System is a nitric oxide administration device intended to add nitric oxide to gases that are to be breathed by a patient, and to be used in conjunction with a ventilator or other breathing system. The ViaNOx includes a nitric oxide, nitrogen dioxide, and oxygen monitor intended to monitor the concentration of these gases in respiratory gas mixtures during administration of nitric oxide.
Device Description
The ViaNOx Delivery System controls the delivery of pharmaceutical grade NO/N2 into the breathing gas stream passing down the inspiratory limb of a patient circuit. The injected flow of NO/Nz is controlled to maintain a steady concentration of NO/Nz within the inspiratory limb at all times, both during and between breaths. Constant concentration operation is accomplished by continuously measuring the flow in the inspiratory limb and adjusting the injected NO/N2 flow rate accordingly. The measure and adjust process is very rapid, and thus provides essentially immediate tracking of changes in the inspiratory flow rate and pattern. The device consists of a cart, a gas plumbing connecting the gas supply to the device, a manual NO delivery system for use with a user supplied manual resuscitator and oxygen supply. a control panel, an NO Delivery Module and the main unit which houses the electronics and most of the software and to which all other components connect.

Not Found

No
The description focuses on real-time measurement and adjustment of gas flow based on sensor data, which is a standard control system function, not indicative of AI/ML. The "Mentions AI, DNN, or ML" section also explicitly states "Not Found".

Yes
The device is a nitric oxide administration system that delivers a therapeutic gas (nitric oxide) to patients in conjunction with a ventilator, which directly implies a therapeutic purpose.

No

The device is described as a nitric oxide administration device that monitors gas concentrations during administration, rather than diagnosing a medical condition.

No

The device description explicitly states that the device consists of hardware components such as a cart, gas plumbing, a manual NO delivery system, a control panel, an NO Delivery Module, and a main unit housing electronics and software. This indicates it is a physical device with integrated software, not a software-only medical device.

Based on the provided information, the ViaNOx Delivery System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use clearly states that the device is for "adding nitric oxide to gases that are to be breathed by a patient" and is used "in conjunction with a ventilator or other breathing system." This describes a device used for administering a therapeutic gas directly to a patient, which is an in vivo application.
  • Device Description: The description details how the device controls and delivers nitric oxide into the patient's breathing gas stream. This further reinforces its role in direct patient treatment.
  • Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, tissue) taken from the human body to provide information about a person's health. The ViaNOx Delivery System does not interact with or analyze patient specimens. While it includes monitors for gases, these are monitoring the gas being delivered to the patient, not analyzing a sample from the patient.

Therefore, the ViaNOx Delivery System is a medical device used for in vivo administration of a therapeutic gas, not an in vitro diagnostic device.
