The Maxxi Position Sensor is intended for use with the BWMini polysomnograph system, to acquire the body position of adult patients during sleep studies. The Sensor produces signals for five positions: supine, prone, left and right. It is intended for use in research, home sleep studies, ambulatory, and clinical environments.

Device Story

Maxxi Position Sensor is a wearable device for sleep studies; attaches to chest or abdominal belts via velcro. Uses electronic tilt switches to detect body position (supine, prone, left, right, upright). Produces 0-1 VDC output signals transmitted via 7ft cable to a polysomnograph (PSG) recorder. Used in clinical, home, or research environments; operated by healthcare professionals. Provides real-time body position data to the PSG system; assists clinicians in correlating sleep disorders with patient posture. Benefits patients by enabling accurate monitoring of position-dependent sleep events.

Clinical Evidence

No clinical trial was performed. Evidence consists of bench testing and a simulated use study with N=20 volunteers. The simulated use study compared the subject device to predicates, reporting 100% accuracy and a 1-second latency difference in detecting body position.

Technological Characteristics

Materials: Plastic ABS enclosure, electronic components, PCB, ABS cable jacket. Sensing: Electronic tilt switches. Energy: 3VDC coin battery. Connectivity: Monopolar DIN 42-802 touch-proof connector. Standards: IEC 60601-1, IEC 60601-1-2. Dimensions: 39x31x15 mm.

Indications for Use

Indicated for adult patients undergoing sleep studies to acquire body position (supine, prone, left, right, upright) for research, home, ambulatory, or clinical environments.

Performance Testing in Simulated Use: A comparative test in simulated use was performed in N=20 volunteers in a simulated use study between the subject device and predicates in order to compare the accuracy and latency to detect the patient's body position in a PSG system. The results showed the average time to detect the patient body position was 1 second of latency difference between the devices and 100% of accuracy between them. This result demonstrated substantially equivalence between the subject device and the predicates. Based on the substantial equivalence comparison, and nonclinical Conclusion: performance tests applied to the Maxxi Position Sensor and the predicates, we conclude that the devices have similar indications for use, technological characteristics and method of action, additionally the nonclinical performance testing demonstrate that the subject device is safe and effectively as well substantially equivalency to the predicates. ## J) Clinical Testing: No clinical trial was performed.
