Indications for Use
The Alio Medical Remote Monitoring System is a wireless remote monitoring system intended for use by healthcare professionals to intermittently collect physiological data in home use settings. The data includes skin temperature, auscultation sound data and heart rate. Data is transmitted wirelessly from the SmartPatch wearable sensor to a web-based portal for the healthcare provider's (HCP) review. The Alio Medical RMS is intended for use on general care patients who are 18 years of age or older. The SmartPatch sensor is indicated to measure skin temperature and pulse rate where clinically indicated. The SmartPatch sensor is indicated to record and transmit auscultation sound data where clinically indicated. The device is not intended for use in critical care or other high-acuity environments. The Alio Medical RMS is a secondary, adjunct patient monitor and is not intended to replace existing standard-of-care patient monitoring practices.
Device Story
System comprises wearable SmartPatch, Bedside Hub, Alio Medical Cloud, and Clinician Portal. SmartPatch (silicone-encased, 7-day wear) uses microphone, accelerometer, thermistor, and PPG (6 LEDs: 2 green, 2 red, 2 IR; 4 photodiodes) to collect skin temperature, heart rate, and auscultation sounds (heart, lung, bowel, arteries, veins). Data transmits via Bluetooth to Bedside Hub, then to Cloud for processing/analysis. Healthcare professionals review data via web-based Clinician Portal. System provides secondary, adjunct monitoring to aid clinical decision-making; benefits include remote physiological data access for general care patients. Used in home environments; operated by patients (wearable) and healthcare professionals (portal).
Clinical Evidence
Bench testing only. No clinical data presented. Verification and validation testing confirmed compliance with safety (IEC 60601-1, 60601-1-11, 80601-2-56, 80601-2-61, 62471, 60529, 60086-4), EMC (IEC 60601-1-2, FCC Part 15), software (IEC 62304), usability (IEC 62366-1), and biocompatibility (ISO 10993-5, 10993-10) standards.
Technological Characteristics
Wearable silicone-encased patch; thermistor, microphone, accelerometer, and PPG (530/650/940 nm) sensors. Connectivity via Bluetooth (patch to hub) and cellular (hub to cloud). Powered by Li-ion battery (patch) and 5V Mains DC (hub). Software developed per IEC 62304. Biocompatible adhesive. Intermittent monitoring mode.
Indications for Use
Indicated for general care patients 18+ years old in home settings for intermittent collection of skin temperature, heart rate, and auscultation sound data. Not for critical care or high-acuity environments.
Regulatory Classification
Identification
A radiofrequency physiological signal transmitter and receiver is a device used to condition a physiological signal so that it can be transmitted via radiofrequency from one location to another, e.g., a central monitoring station. The received signal is reconditioned by the device into its original format so that it can be displayed.

#### 6. Device Description
Alio Medical Remote Monitoring System, or "Alio Medical RMS", utilizes a wearable device (SmartPatch) on the skin to gather physiological data and then transmits it to a device (Bedside Hub) located in the subject's home. The Bedside Hub then relays this raw data to the Alio Medical Cloud where it is processed and analyzed using Alio's proprietary algorithms. Data is accessible to Healthcare Professionals and the Alio clinical team via a web-based Clinician Portal. The SmartPatch and Bedside Hub are intended to be used on general care patients who are 18 years of age or older in a non-clinical environment. The web-based Clinical Portal is to be used by healthcare professionals in an office environment.
The Alio Medical Remote Monitoring System includes the following components:
- SmartPatch
- Bedside Hub
- Alio Medical Cloud (backend only - not user facing)
- Clinician Portal
## SmartPatch
A flexible, silicone-encased patch that can be worn where clinically indicated for up to seven days at a time. It houses numerous sensor technologies, which include a microphone, accelerometer, temperature sensors, and a PPG sensors collect physiological data including skin temperature, auscultation sound data, and heart rate. Data is transmitted to the Cloud, via the Hub, where it is analyzed and sent to a Healthcare Professional via the Web Portal.
## Bedside Hub
The Bedside Hub has the form and finish of an at-home device. It automatically communicates with the activated SmartPatch and uploads physiological data to the Alio Medical Cloud.

The "al" part of the word is in gray, and the "io" part of the word is in purple and is shaped like a circle. Below the word "alio" is the word "MEDICAL" in gray.
# Alio Medical Cloud
The Cloud features a database that supports storage, analytics, system monitoring and visualization capabilities. The Alio Medical Cloud is encrypted and HIPAA compliant. All patient data is fully traceable to device and patient ID via the database.
# Clinician Portal
The Clinician Portal is the interface tool between a user (healthcare professional users only) and the system that enables the user to visualize and interact with data being generated by the system.
Note - none of the above components/accessories of the Alio Medical RMS have received prior 510(k) clearance.
