1.1 Introduction, Warnings, and Safety The Eko Electronic Stethoscope System (herein referred to as Eko) is designed to support healthcare professionals in analyzing cardiac and other internal organ sounds. Eko includes a device that is attached to a stethoscope (Core), a smartphone application (App), and a web application (Dashboard).
1.3 Safety Related Labels & Symbols Consult instructions for use. This product contains electrical and electronic components and must not be disposed of using standard refuse collection. Please consult local directives for disposal of electrical and electronic equipment. This product and packaging does not contain natural rubber latex. This product contains an intentional RF radiator certified by the FCC.
CAUTION: • To reduce the risk of device interference, keep the Eko Core at least 1 meter away from all RF emitters including Wifi routers and radios. • To reduce the risks associated with infection follow all cleaning and disinfecting instructions included in this manual. Establish and follow a cleaning and disinfecting schedule. • To reduce the risks associated with inaccurate data acquisition store and operate this stethoscope only as instructed in this manual.
NOTICE: and cause interference, immediately move Core away from that device and/or turn the Bluetooth feature OFF. • To reduce the risks associated with environmental contamination follow applicable regulations when disposing of this stethoscope. The Eko Core stethoscope attachment contains a lithium-ion polymer rechargeable battery; please properly dispose of the device as mandated by local directives. • No modification of this equipment is allowed. There are no repairable parts inside the Eko Core. 1.
1.6 Indications for Use Eko is intended to be used as a part of a physical assessment of a patient by healthcare professionals for diagnostic decision support in clinical settings. Eko is intended for use on pediatric and adult patients. It can electronically amplify, filter, and transfer sounds to the accompanying mobile application for storage and sharing.
In order to transmit sounds to the Eko App, the stethoscope and device must be connected via Bluetooth, and in order to fully use certain functions, the mobile device must be connected to the internet via cellular data connection or Wi-Fi. Core uses a Bluetooth Class 2 wireless data link. The Bluetooth range will be reduced when objects (walls, furniture, people, etc) are between the Core and a paired mobile device.
1.9 Contents and Operation The Core package includes (1) Eko Core, (2) stethoscope tubing adapters, (1) micro USB cable, and (1) USB charger. This device is non-assembled and must be installed by the user. For full functionality, the system requires an acoustic stethoscope and smart mobile device with wireless Internet capabilities (not included). The compatible hardware and software platforms are listed below.
2.1 Installation to Existing Stethoscopes Not applicable to Eko Bundle Detach Chest Piece Remove chest piece of the analog stethoscope manually. Grip the chest piece with one hand and the tubing in the other, then twist and pull them apart. This may require some force. See Fig. 1 & 2 Fig. 1 Detach the Chest Piece Fig. 2 Detached Chest Piece Install Eko Core Insert the narrow end of the Core into the tubing of the stethoscope. The metal stem fits into the hollow opening of the tube.
Reattach Tubing and Chest Piece Attach the additional tubing connector onto the end of the Core as shown below. Then attach the chest piece into the tubing connector as it was on the analog stethoscope. To get the best sound, we recommend you test all Eko-supplied tubing adapters & select the one that provides the tightest fit with your analog stethoscope. Fig. 5 Core with Attached Tubing Fig. 6 Completed Installation 2.
Test the Volume Level The Core’s sound level can be amplified in 7 increments up to 20X amplification of an acoustic stethoscope. Change the volume level by clicking the plus (+) and minus (-) volume buttons on the side of the Core. Bluetooth Pairing First, enable Bluetooth on the selected mobile device. On the iOS device go to Settings > Bluetooth > and tap the slider to turn Bluetooth ON. Then, navigate to the Menu screen by clicking on the top left tab in the App.
3.1 Cleaning Cleaning and Disinfecting Procedure The stethoscope and Core should be cleaned between each patient use. All cleaning instructions pertaining to the original stethoscope apply. Under normal conditions it is unnecessary to remove the Core from the stethoscope tubing for cleaning. All external parts of the hardware can be cleaned with 70% isopropyl alcohol wipes. NOTE: DO NOT immerse the device in any liquid or subject it to any high-pressure/autoclave sterilization processes.
4.1 Warranty Eko provides a limited warranty for Core Model E4. Please visit ekodevices.com/warranty for a full description of the warranty.
5.1 Operating Conditions Environmental The operating range of the Core is -30° to 40°C (-22° to 104°F), and 15% to 93% relative humidity. The storage and transport range is -40° to 55°C (-40° to 131° F), and 15% to 93% relative humidity. Acceptable pressure is 1 atm. It is recommended to avoid exposure to extreme heat, cold, solvents and oils. Extreme heats and colds will negatively affect the lithium ion battery in the device, and may affect battery life.
On (quick blink) Playback The Core is ON and playing back sounds from a paired phone/tablet. On Volume Change The Core is ON and changing playback volume based on commands from the volume buttons or paired phone/tablet. The LED will blink once for each volume interval changed. On Low Battery The Core is ON and its battery level is below 25%. On Battery Expired The Core is ON and its battery level is below 10%. The Core will no longer stream or playback audio.
