Intended Use
The PRESSUREALERT® Pressure Monitoring System monitors the activity of patients who are susceptible to pressure ulcers by measuring pressure at various points of the body. It allows healthcare providers to medividualized turn management plan for each patient by continuously monitoring pressure on various points of the body of each patient. The PRESSUREALERT® Pressure Monitoring System provides alerts when patient activity deviates from the pressure prevention parameters set for by the healthcare providers. The device is in medical, nursing, and longterm care facilities including independent living, assisted living, and rehabilitation facilities.
Device Description
The PRESSUREALERT® Pressure Monitoring System is composed of a wireless pressure sensing dressing assembly as part of a system supported by the PRESSUREALERT® Management Software for providing a warning to the healthcare provider that soft tissue pressure has exceeded a predetermined level that, over a period of time, would necessitate that the patient should be moved to prevent or at least reduce the risk of soft tissue damage. The PRESSUREALERT® Pressure Monitoring System functions as a pressure monitoring system with the primary function to monitor a patient that is laying down on their back or otherwise in a position that may result in the patient's weight applying pressure to an area of the patient's body that is susceptible to pressure ulcers/injuries, such as soft tissue overlying a bony prominence. The dressing assembly, with the enclosed pressure sensor, is applied on the patient's body that is susceptible to damage from soft tissue pressure. The identified areas are referred to as "at-risk" in the instructional documentation and intended use and include up to eleven (11) sites defined as the upper spine, head-skull, hip (right or left), Ischia (right or left), heels and elbows (right or left), and sacrum. The material components of the PRESSUREALERT® Pressure Monitoring System, and described in detail in the Device Description section, includes: - i. PRESSUREALERT® Segmented Oval Dressing - ii. PRESSUREALERT® Round Dressing - iii. PRESSUREALERT® Sacral Dressing - iv. PRESSUREALERT® Oval Sensor - v. PRESSUREALERT® Round Sensor
More Information

No
The summary describes a system that monitors pressure and provides alerts based on predetermined levels set by healthcare providers. There is no mention of AI or ML being used for analysis, prediction, or learning from data. The system appears to be based on simple threshold-based alerting.

No.
The device is a monitoring system designed to alert healthcare providers to high-pressure areas to prevent pressure ulcers, rather than actively treating a medical condition.

Yes

The device monitors pressure at various body points and provides alerts when activity deviates from set parameters designed to prevent pressure ulcers, indicating it identifies conditions that may lead to a medical problem.

No

The device description explicitly states that the system is composed of a "wireless pressure sensing dressing assembly" and lists physical components like "PRESSUREALERT® Segmented Oval Dressing", "PRESSUREALERT® Round Dressing", "PRESSUREALERT® Sacral Dressing", "PRESSUREALERT® Oval Sensor", and "PRESSUREALERT® Round Sensor". These are hardware components, not solely software.

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

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The PRESSUREALERT® Pressure Monitoring System directly monitors pressure on the patient's body surface. It does not analyze any biological specimens.
  • Intended Use: The intended use is to monitor patient activity and pressure points to help prevent pressure ulcers, not to diagnose a condition based on laboratory analysis of a specimen.

The device is a non-invasive monitoring system that interacts with the patient's external body surface.

8. Discussion of Technological Differences

Body Site Location – Location for the predicate device is a single location (chest). The subject device can be located on 11 different areas of the body and can report repositioning data. This difference raises no new issues of safety and effectiveness because of verification and validation of the software. The subject device detects activity via pressure changes; the predicate device detects activity via orientation changes with an accelerometer.

Mechanism of Use - The subject device, unlike the predicate, does not utilize USB relay / antennas mesh network with antenna. The subject device incorporates the latest wireless technology to accomplish the same data transfer and raises no new issues of safety and effectiveness.

Sensor Size - The subject device has a larger contact area compared to the predicate device, but the adhesive used in both devices is a medical grade commonly used in medical dressing. The sensor size difference raises no new issues of safety and effectiveness.

Non-skin Contact Material – Both the subject device and the predicate device provide a patient non-contact sensor by encapsulating the sensor inside a covered component that is attached to the patient's skin by use of a medical grade adhesive commonly used in medical dressings. The subject device non-contact sensor can be removed from the dressing to change the dressing as needed whereas the predicate sensor is sealed. The sensor non-skin contact differences raises no new issues of safety and effectiveness.

Battery Life - The subject sensor battery life, once activated, can be used up to 25 days and 1 year if not activated. The predicate sensor battery life, once activated, can be used up to 21 days, The difference between sensor battery life of the predicate and subject device 21 days and 25 days once activated raises no new issues of safety and effectiveness.

Non-Clinical Test Result Summary

The Product Comparison discussions of the technological differences, and the conclusions the non-clinical testing; those results demonstrate that drawn from the PRESSUREALERT® Pressure Monitoring System is substantially equivalent to the predicate device. Non-clinical testing included Ingress protection testing, drop testing, and battery life testing. Regarding the Ingress protection testing, the tests performed on the PRESSUREALERT® Pressure Sensors and Pressure Sensor Dressings included the IP4X 1 mm Sphere test and the IPX7 temporary water immersion test. There were no unexpected results, and the results of both tests were a "Pass".

The drop test required that the PRESSUREALERT® Pressure Sensors pass the

13

functionality parameters and have no visual signs of damage. Again, there were no unexpected results, and the test was given a "Pass". The battery life test for the Sensor's Lithium battery was performed and there were no unexpected results, and the sensor has a "Pass" for a calculated maximum storage battery life of 1 year and an activated operating life of 25 days. The battery life parameters were based on a maximum storage temperature of +70°C and an activated battery operating temperature range of +5°C to +40°C. The use of the worst-case temperature scenario was determined to be the basis for the recommended operating use and storage life. Finally, the third party non-clinical testing has shown that after extensive pressure sensor performance (activation pressure test) testing, the PRESSUREALERT® Pressure Monitoring System sensor attained the required threshold of 32 mmHg (equivalent to 43.5 g/cm²).
