The Byteflies Kit (Model 1) is a wearable CE Class I medical device for continuous recording of non-invasive physiological and behavioral signals in healthcare and home settings. The Byteflies Kit instructions for use (IFU) contains all the information required for safe and correct use of the Byteflies Kit. This page summarizes relevant safety and regulatory information.
- Byteflies Kit
- The collective name for all components of the medical device.
- Sensor Dot
- A 2-channel biopotential and tri-axial inertial measurement device, indicated for recording electroencephalography (EEG), electrocardiography (ECG), heart rate (HR), respiratory rate (RR), electromyography (EMG), electrooculography (EOG), acceleration (ACC), angular velocity (GYR), and activity index (AI).
- Sensor Patch
- An interface between a Sensor Dot and the body. A Byteflies Kit comes with a specific Sensor Patch: the 4-wire Cradle (see the IFU(/docs/hcp/kit/) for more information).
- Docking Station
- A component that can charge up to 5 Sensor Dots and provide a secure communication gateway to the Byteflies Cloud to upload recorded data.
- Byteflies Cloud
- A secure data storage and processing system for data recorded by Sensor Dots.
The Byteflies Kit is a multisensor device intended to collect non-invasive physiological and behavioral signals to be used in the clinic and/or home for Users that need continuous monitoring.
- Trained Operator
- A healthcare professional trained in the usage of Byteflies Kits and its accessories.
- A patient or subject with a clinical need for biopotential and/or motion monitoring and/or their caregiver.
The Byteflies Kit and its accessories are intended to be used by Trained Operators who configure the Byteflies Kit and its accessories in a medical environment (e.g. hospital). Users are wearers of the Sensor Dot, not operators of the Byteflies Kit, and are 4 years of age or older. Once the correct set up is configured, the User can take the Byteflies Kit and applicable accessories home to continue recording data as instructed by the Trained Operator. The User may be required to return to the medical environment for removal or reconfiguration of Byteflies Kit components and accessories by the Trained Operator.
The Byteflies Kit and its accessories are intended for prescription use in the home, healthcare facility, or clinical research environment to acquire, record, and transmit physiological and behavioral signals from Users. It acquires, records and transmits electroencephalogram (EEG), electrocardiogram (ECG), heart rate (HR), respiratory rate (RR), electromyogram (EMG), and/or electrooculogram (EOG) signals, with optional accelerometer (ACC), gyroscope (GYR), and activity index (AI) signals. It only acquires these signals, no diagnostic claims are made about the User’s condition.
The Byteflies Kit and its accessories should not be used on Users that:
- Have been diagnosed with or are suspected to have life-threatening conditions that could result in immediate danger;
- Need to undergo an MRI scan or cardiac defibrillation;
- Have an active implanted device such as a pacemaker, defibrillator, or vagal nerve stimulator;
- Are between 0 and 3 years of age.
The following is important information for using the Byteflies Kit properly and safely. Carefully read this section before operating any component. The Byteflies Kit is a biopotential and motion recording device comprised of hardware and software that has been tested to assess its safety and effectiveness, and to establish substantial equivalence with predicate devices.
- The Byteflies Kit cannot provide diagnoses. It only records physiological and behavioral signals as configured by and under the authority of the Trained Operator.
- The Sensor Dot LED patterns only reflect battery status and operation mode. The LED does not reflect physiological status in any way and should never be interpreted as an indication of patient health.
- The Byteflies Kit is designed to be operated by a Trained Operator. The User should always receive proper instructions from a Trained Operator before using any component of the Byteflies Kit.
- The Sensor Dot, Sensor Patch, and Docking Station are only intended to be used by the User as instructed by the Trained Operator and the User cannot configure any component of the Byteflies Kit.
- The data recorded by a Sensor Dot can only be used to asses heart, brain, muscle, or motion-related diseases when reviewed by a properly trained healthcare professional (e.g. a cardiologist, pulmonologist, neurologist, physiologist …).
- Sensor Dots interface with the human body via Sensor Patches. Sensor Patches for monitoring of biopotential (ExG) signals are compatible with certain commercial ExG electrodes. These are not supplied as part of the Byteflies Kit. The use of any skin adhesives may cause mild skin irritation, such as redness, itching, or contact dermatitis in some Users. Consult the manufacturer of the ExG electrodes for more information.
Do not use any component of the Byteflies Kit before reading these warnings, the IFU and -if applicable- a manual for the ExG electrodes or Byteflies accessories:
- Do not use the Byteflies Kit if any component is damaged.
- The Byteflies Kit is provided non-sterile.
- Please verify the LED status indicators to avoid misuse.
- If the Trained Operator or User experience any adverse events while using a Byteflies Kit, discontinue the use and contact Byteflies immediately.
- Skin adhesives (either provided by Byteflies as an accessory or from a compatible 3rd party provider) should be replaced if they no longer stick firmly to the skin or as indicated in their respective manuals.
- Similar devices may cause signal interference during data transmission. Avoid operating the Byteflies Kit near interfering devices.
- Keep the Byteflies Kit away from children and pets. The Sensor Dot and Sensor Patch may present a choking hazard, never place or let anyone place a component of the device in their mouth.
- If any component of the Byteflies Kit fails to operate after attempting all suggested troubleshooting steps, contact support as soon as possible.
- The battery used in a Sensor Dot may present a risk of fire, explosion, or chemical burn if mistreated. Do not expose Sensor Dots to excessive heat or fire. Do not crush, puncture, or incinerate as doing so can result in fire, explosion or the release of toxic gasses. Do not use or charge if a Sensor Dot appears to be leaking, discolored, deformed, or in any way abnormal.
- All components of a Byteflies Kit should be returned to the healthcare provider or study staff at the conclusion of the prescribed period of use.
- Do not use a Sensor Dot on a User without first cleaning it according to the instructions.
- Do not use a Byteflies Kit without first charging the Sensor Dot(s) and completing proper set up as described in the IFU.
- Do not use a Sensor Dot on Users undergoing an MRI scan.
- Do not use a Sensor Dot on Users undergoing defibrillation.
- Do not use a Sensor Dot on Users with an active implanted device, such as a pacemaker, defibrillator, or vagal nerve stimulator.
- Do not expose a Sensor Dot to strong sources of static electricity.
- Do not expose a Sensor Dot to strong electromagnetic fields.
- Do not leave a Sensor Dot on top of or next to other electrical equipment.
- Do not submerge any component of a Byteflies Kit in liquid.
- Do not clean a Sensor Dot with agents other than those listed in the cleaning instructions.
- Do not damage any component of the Byteflies Kit through drops, violent shaking or crushing.
- Do not allow Sensor Dots to come into contact with conductive materials, except when following instructions on how to recharge the battery.
- Sensor Dot is not a toy. Usage on children older than 3 years of age should be under strict supervision of an adult.
- Do not alter any component of the Byteflies Kit. Any modification is strictly prohibited.
- Do not use at temperatures lower than 15°C or greater than 35°C.
- Do not use where air humidity is lower than 10% or higher than 90%.
- Do not use in environments subjected to pressure lower than 700 hPa or greater than 1080 hPa.
- Do not use a Docking Station with a charger and charging cable other than the one supplied with the Byteflies Kit.
