More Information

No
The summary describes a hyperbaric chamber, a physical pressure vessel with associated control systems for delivering hyperbaric oxygen therapy. There is no mention of any software or algorithms that would suggest the use of AI or ML for diagnosis, treatment planning, or any other function. The performance studies focus on physical, electrical, and software validation of the chamber's control systems, not on the performance of any AI/ML model.

Yes
The device is intended to treat a variety of medical conditions as listed in the 'Intended Use / Indications for Use' section, which defines its therapeutic purpose.

No

The device description clearly states it is a "Hyperbaric Chamber," a pressure vessel designed for hyperbaric oxygen therapy, not for diagnosing medical conditions. The "Intended Use / Indications for Use" section lists conditions that the device treats, not conditions it identifies or diagnoses. The performance studies also focus on safety, electrical compatibility, and functional aspects of the chamber, rather than diagnostic accuracy.

No

The device description clearly details a physical hyperbaric chamber, including its construction, configurations, features (fire protection, compressed air system, etc.), and compliance with physical standards (ASME PVHO-1, NFPA). The performance studies also include testing related to the physical chamber and its components (biocompatibility, electrical safety, bench testing). This is not a software-only device.

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

Here's why:

  • Intended Use/Indications for Use: The intended uses listed are all related to treating various medical conditions in a patient by administering hyperbaric oxygen therapy. This is a therapeutic intervention, not a diagnostic test performed on samples taken from the body.
  • Device Description: The device is a hyperbaric chamber, a physical structure designed to create a high-pressure environment for a patient. It includes systems for fire protection, air and oxygen delivery, environmental control, power, and control. These are all components of a therapeutic device, not a diagnostic one.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens (blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or screening. The device's function is to deliver a treatment.

Therefore, the FINK Hyperbaric Chamber is a therapeutic device, not an In Vitro Diagnostic device.

The addition of the PLC control with manual back is the same as the reference device. This type of control mechanism change has been implemented in a number of 510(k) submissions. The PLC change does not raise new or different questions of safety and effectiveness. The change can be supported with data. The OxyHeal device is cited as a reference device to support the test methods which is primarily software verification and validation.

Other minor changes have been also been supported with the appropriate supportive testing and do not raise new issues of safety or effectiveness.
