BioStamp nPoint User Manual
BioStamp nPoint is a wireless remote monitoring platform intended for use by healthcare professionals and researchers for the continuous collection of physiological data in healthcare and home settings. BioStamp nPoint is designed to capture objective, real-world data from study subjects participating in clinical or academic studies, and may be used wherever collection of relevant data is needed.
BioStamp nPoint centers on body-worn BioStamp Sensors that can be worn for up to 24 hours at a time in both laboratory (clinic) and home settings. Investigators (either researchers or physicians) design studies and the data to be collected using a web-based study conguration tool, called the Investigator Portal. For laboratory or clinic (“Supervised”) settings, BioStamp nPoint includes a Tablet Investigator Application (“Investigator App”) to be used for the set-up and conguration of the sensors. When BioStamp nPoint is used in the home or outside of the clinic (“Remote”) setting, study subjects interact with the system through a Mobile Phone Application called the “Link App.” The recharging and data transmission hub (“Link Hub”) is used to recharge the sensors and synchronize data from the Sensors. BioStamp nPoint includes an algorithm package that delivers a dashboard presentation of processed metrics on general activity (including step count and activity classication), heart rate, heart rate variability, posture (body position relative to gravity), sleep, and respiration during sleep. The system is also capable of surface electromyography and monitoring limb and body movements during daily living and sleep. Data are transmitted wirelessly from the Sensors through the Link Hub to the MC10 Cloud for storage, processing, and analysis.

BioStamp nPoint User Manual
The adhesives are intended to adhere the Sensors to the body for up to 24 hours.
Under certain conditions the provided adhesive might not be sucient (e.g. prolonged swimming, very intense exercise) to adhere the Sensors to the body for the full 24-hour wear duration. The Dorsal Foot and Dorsal Hand locations are particularly prone to adhesion issues due to the movement and body morphology of these specic areas. MC10 recommends providing an additional method of securing the Sensors to these body locations and for use during certain activities.
Apply the Adhesive Stickers to Sensors
Each adhesive will be pack­aged individually in a sealed foil pouch. Do not open the adhesive pouch until you are ready to apply the adhesive to the Sensor.
Adhesives
BioStamp Sensors are applied to the body using disposable adhesives for attachment that also contain hydrogel to optimize electrode contact to the skin. These double-sided adhesives have a sensor-side and a skin-side and should be applied to the Sensor using the provided applicator as a guide.
For locations outside of the required analytics sensor locations (see Investigator Portal Study Design), extra means to secure the sensors to the body are recommended (e.g. TegadermTM, CobanTM wrap).

Programmable Electrical Medical System (PEMS) connection to an IT-Network
Data is transferred continuously among components during normal system operation. Raw (unprocessed) sensor data is transferred wirelessly from the patch to the mobile through Bluetooth LE. When network connectivity is available, sensor data is transferred from the mobile to the cloud. Once the cloud conrms receipt of the sensor data, the patch’s on-board ash memory may be cleared for subsequent recording.
Implemented Protocols
BLE, USB, and HTTP standard protocols are implemented between the PEMS and the IT-network. These protocols encompass and incorporate the required characteristics of the IT-network incorporating the Portable Emissions Measurement System (PEMS), the required conguration of the IT-network incorporating the PEMS, and the technical specications of the network connection of the PEMS including security specications.

Information Flow
The intended information ow between the PEMS, the IT-network and other devices on the IT-Network, and the intended routing through the IT-network:
This can include aspects of eectiveness and data and system security as related to basic safety and essential performance (see also Clause H.6 and IEC 80001-1:2010).

Sensor to Mobile Communication
Data stored on the patch’s on-board memory is secured through a proprietary bit packing and memory block allocation scheme. Communication to the patch is only enabled through custom-built mobile applications. All MC10 applications require an authorized user login using valid credentials. During operation, each patch is uniquely assigned to a subject, in a specied conguration mode which includes the sensor modality and body location. Patch to mobile and mobile to patch communication is secured through a custom cmd-ctrl-data protocol and compression algorithm that runs across the Bluetooth LE protocol packets.
Mobile to MC10 Cloud Communication
Application data is encrypted (256-bit AES) and stored on the local SQLite database on the mobile.
Upon network connectivity, data is transmitted between the mobile and cloud using HTTPS protocols, which requires authentication with valid credentials. This encrypted connection protects the privacy and integrity of the exchanged data.
All cloud API interactions are logged with the following attributes:
Authenticated user taking the action
Source IP address of user
Time of interaction
Resources viewed or action taken
MC10’s cloud network and systems are protected with standard security practices (rewalls, VPC, access restrictions, and automated conguration management). Access to the data is restricted at multiple levels and is protected by MC10’s Access Control Lists (ACLs) framework. ACLs restrict resource availability to approved users and groups. Each user belongs to at least one group and is assigned one or more roles within their respective group. Roles dene which resources and what actions are available to a user in a given group.
Hazardous Situations
Potential hazardous situations resulting from a failure of the IT-NETWORK to provide the characteristics required to meet the purpose of the PEMS connection to the IT-NETWORK:
Investigator Portal, Investigator App, and/or Link App cannot connect to public internet;
56
BioStamp nPoint User Manual
Investigator Portal, Investigator App, and/or Link App can’t connect to MC10 MDDS;
Erroneous data transfer between Investigator Portal, Investigator App, and/or Link App and MC10 Cloud;
Data corruption on MC10 Cloud due to foreseeable misuse (i.e. hacking);
Investigator App or Link App can’t congure/control BioStamp Sensor;
Link Hub cannot control/download BioStamp Sensor;
Erroneous data transfer between BioStamp Sensor and Link Hub;
Link App cannot control/download smart charger;
Erroneous data transfer between Link App and Link Hub;
Data corruption on smart charger due to foreseeable misuse (i.e. hack­ing).
Connection of the system to an IT-network that includes other equipment could result in previously unidentied risks to patients, operators, or third parties. The responsible organization should identify, analyze, evaluate and control these risks. Subsequent changes to the IT-network could introduce new risks and require additional analysis. Changes to the IT-network include:
changes in the IT-network conguration;
connection of additional items to the IT-network;
disconnecting items from the IT-network;
update of equipment connected to the IT-network;
upgrade of equipment connected to the IT-network.
