Intended Use
The Guardian Angel Rx GA2001 Digital Vital Sign Monitoring System is indicated for use in measuring and displaying functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate. It is indicated for spot-checking and/or continuous monitoring of pediatrics and infants during non-motion and under well-perfused conditions. The intended environments of use are hospitals, medical facilities, home care, and subacute environments. This system is a reusable device.
Device Description
The subject device is a digital vital sign monitoring system that measures and displays a patient's pulse rate and oxygen saturation (SpO₂). It is also equipped with an audio/video camera to monitor the patient in real time. In addition, the subject device provides visual and auditory alarms that alert the caregiver when a patient's pulse rate and/or SpO2 falls outside of preset limits or when a technical error is detected. During a physiological alarm event, the pulse rate and SpO2 data along with the audio/video data are recorded automatically by the subject device. The caregiver can review the historical data whenever needed. The system consists of a self-contained foot-worn Sensor Module, a Receiver/Transponder with an embedded audio/video camera and a portable, table-top wireless Display Unit. It uses non-invasive red and infrared technology to measure the pulse rate and SpO2. The measurements are taken by the Sensor Module and are transmitted to the Receiver/Transponder which delivers the measurements along with audio/video signals to the Display Unit for display, wherein Bluetooth technology is used to transmit data between the Sensor Module and the Receiver/Transponder, and data is transmitted from the Receiver/Transponder to the Display Unit via the Wi-Fi 802.11 band.
More Information

No
The description focuses on standard vital sign monitoring technology (pulse oximetry) and data transmission, with no mention of AI or ML algorithms for data analysis, interpretation, or prediction. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".

No
The device is a monitoring system that measures and displays vital signs and does not provide any treatment or therapy.

Yes

Explanation: The device measures and displays functional oxygen saturation (SpO2) and pulse rate, which are vital signs used by healthcare professionals to assess a patient's physiological state and identify potential health issues, falling under the definition of a diagnostic device.

No

The device description explicitly states that the system consists of hardware components: a self-contained foot-worn Sensor Module, a Receiver/Transponder with an embedded audio/video camera, and a portable, table-top wireless Display Unit.

Based on the provided information, 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. They are used to examine specimens outside of the body.
  • Device Function: The Guardian Angel Rx GA2001 Digital Vital Sign Monitoring System measures and displays functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate. It does this using non-invasive red and infrared technology applied to the foot. It also includes audio/video monitoring.
  • Method of Measurement: The measurements are taken directly from the patient's body (the foot) using light technology. This is an in vivo measurement, not an in vitro measurement of a sample taken from the body.

Therefore, the device's function and method of operation clearly fall outside the definition of an In Vitro Diagnostic. It is a non-invasive physiological monitoring device.

7.8 Summary of Performance Testing

The performance data are summarized below in support of the substantial equivalence determination.

Biocompatibility testing

The biocompatibility evaluation for the subject device was conducted in accordance with ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The battery of testing included the following tests:

  • Cytotoxicity
  • Sensitization
  • Irritation

Electrical safety and electromagnetic compatibility (EMC)

Electrical safety and EMC testing were conducted on the subject device. The device complies with the IEC 60601-1, IEC 60601-1-11, IEC 60601-1-8 and ISO 80601-2-61 standards for safety and the IEC 60601-1-2 standard for EMC.

Software Verification and Validation Testing

Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices."

Clinical Study

Clinical data were collected, according to Clause 201.12.1.101.2 and Annex EE.2 of ISO 80601-2-61:2011 Standard, to verify the accuracy of the subject device on healthy subjects over the range of 70%-100% SpO2 through controlled induced hypoxia. Over 200 data points were collected. The Arms is below 3%, compliant with FDA quidance on Pulse Oximeters - Premarket notification submissions [510(k)].

7.9 Substantially Equivalent Conclusion

Based on the non-clinical testing and clinical data summarized in this 510(k) submission, the results demonstrate that the subject device is substantially equivalent to the predicate. The differences do not raise different questions of safety or effectiveness when compared to the predicate.
