  • Page 5: Important Information

    Trigno™ Wireless Biofeedback System Important Information Intended Use The Trigno Wireless Biofeedback System is a battery-powered biofeedback device that enables researchers and clinicians to acquire EMG and related signals from subjects for biofeedback and research purposes. They are intended for relaxation training and muscle reeducation. Interpretation of the EMG and supporting signals by a qualified individual is required.

  • Page 6: Warnings And Precautions

    Connect only to Delsys-approved devices. Connecting a patient to high-frequency surgical equipment while using Delsys EMG systems may result in burns at the site of the EMG sensor contacts Immediately discontinue device use if skin irritation or discomfort occurs.

  • Page 9: Trigno System Overview

    Wireless Biofeedback System is a device designed to make EMG (electromyographic) and biofeedback signal detection reliable and easy. The system transmits signals from the Trigno Galileo sensors to a receiving base station using a time-synchronized wireless protocol which minimizes data latency across sensors.

  • Page 10: Onboard Emg Sensor

    Data from each sensor and from each channel within a sensor are time synchronized over the Trigno wireless communication protocol so no time skew between data exists. A maximum of 4 Trigno Galileo sensors can stream data to a host base station at one time. These features are available only when communicating with the PC-connected Base Station;...

  • Page 11: Internal Magnetic Switch

    Trigno™ Wireless Biofeedback System Internal Magnetic Switch The Trigno Galileo sensors are equipped with an internal magnetic switch which is used to turn the sensors “on” and to perform RF pairing operations. To activate the internal magnetic switch, the sensor must be placed on the magnet lock label located on the Base Station charging cradle.
  • Page 12 A magnetic field will turn the sensor on within 6 seconds, otherwise the arrow fades to dark and sensor turns off. 3) Charging: Sensor Charging in the Trigno Base Station is denoted by continuous amber LED arrow illumination 4) Charge Complete: Once the internal sensor battery has been fully recharged, the LED arrow illuminates to continuous green.

    • Medical Grade Universal Power Supply. Figure 1: Trigno System Base Station for sensor recharging and communication. Recharging Cradle: The Trigno Base Station is equipped with 16 charge pockets which can accommodate Trigno sensors for charging. The pockets are keyed so that sensors can only be inserted in one orientation.

  • Page 15: Getting Started With The Trigno System

    Trigno Systems are equipped with a universal medical power supply and are provided with interchangeable country-specific plug adapters. Connect the Trigno power supply to the circular DC jack located on the side of the Base Station. Energize the power supply by connecting it to a Mains outlet or to an isolation transformer.

  • Page 16: Turning The Sensor On

    Turning the Sensor ON Trigno Galileo sensors are automatically turned on when they are removed from a powered charging dock. The sensors must be docked for a minimum of 3 seconds in the charge cradle, however, for the self-powering scheme to initiate upon undocking.

    Trigno™ Wireless Biofeedback System Figure 4: To turn sensors on: a) dock for 3 seconds or more, b) remove from cradle, c) tap sensor on magnet within 6 seconds to (d) complete power-up sequence. Turning the Sensors OFF There are 3 mechanisms that will turn the sensors off:...

  • Page 18: Startup Scan Mode

    Trigno™ Wireless Biofeedback System Startup Scan Mode Once the sensors turn on and complete the activation process, the LED will alternate between amber and cyan, indicating that the sensor is looking for a connection to the host. The host can either be a PC-connected base station or a Bluetooth enabled Android device.

  • Page 19: Acquiring Data With The System

    Microsoft Windows Operating Systems can be downloaded from the Delsys website (www.delsys.com) or installed following the information included with the system. Acquiring data with a PC requires the Trigno Base Station to be connected via the USB port. The Trigno Base Station uses a custom RF protocol to guarantee high data bandwidth across 16 sensors with no inter-sensor latency.

    Trigno™ Wireless Biofeedback System Configuring the Trigno Sensors Once paired to the system, EMG data and IMU data from sensor can be configured in the following ways: Electromyographic (EMG) Sensing Ranges Input Range 11 mV Bandwidth 20-450 Hz Inertial Measurement Unit (IMU) Ranges Accelerometer* ±2 g...

  • Page 21: Using The Wireless Emg Sensors

    Using the Wireless EMG Sensors Orienting the EMG Sensors on the Skin Trigno EMG Sensors employ 4 silver bar contacts for detecting the EMG signal at the skin surface. For maximum signal amplitude, it is important to orient these bars perpendicular to the muscle fiber direction. The top of the sensor is shaped with an arrow to aid in the determination of this orientation.

Immediately discontinue use if skin irritation or discomfort occurs. Patients with sensitive skin may experience temporary redness and irritation.

  • Page 23: Using The Analog Outputs (If Equipped)

    Trigno™ Wireless Biofeedback System Using the Analog Outputs (if Equipped) The Trigno System provides simultaneous analog signal reconstruction of data being detected by all active sensors. These signals are made available on the 68-pin connectors located on the Base Station and range cover the +/-5V range.
