The EOVE EO-70 Secretion Management Device (SMD) is designed to assist adult and pediatric patients weighing at least 5 kg (11 lbs) who require support in managing their secretions. It offers two primary treatment modes: Insufflation – Exsufflation (INEX) and Intermittent Positive Pressure Breathing (IPPB). The device is suitable for use in home, institutional, and hospital settings, accommodating both invasive and non-invasive interfaces such as masks, mouthpieces, or tracheostomy tubes. While transportable, it is not intended for use during transport.

Function Description:

The EO-70 provides mechanical insufflation and exsufflation to clear secretions from the airways. In INEX mode, it delivers positive pressure to inflate the lungs (insufflation) followed by negative pressure to assist with exhalation (exsufflation), simulating a cough. In IPPB mode, it delivers positive pressure breaths to assist with inspiration. The device can be operated in either manual or automatic modes, with various adjustable parameters to customize treatment. A coaching function, featuring animated visuals (chameleon and balloon), is available to guide patients through treatment phases, particularly in INEX Auto mode and IPPB mode, helping them synchronize with the device's cycles.

Presets: The device can store up to three different treatment presets, configured by clinicians for personalized alternative treatment options.
SMD Module (Click and Go): The SMD module can be detached from the docking station for standalone use, offering portability. To remove, the device must be turned off and unplugged, a screw at the bottom of the station removed, and the module pushed from the back while holding the docking station.
Touch Pad: In INEX Manual mode, the touch pad allows for manual control of inspiration and exhalation by sliding a finger right or left. In IPPB mode, a simple touch triggers an inspiration.
Coaching Function: An animated chameleon and balloon guide the patient through treatment phases, providing visual feedback during inhalation, exhalation, and pause times.

Alarms: The device is equipped with an alarm indicator to alert the user to technical issues or low battery. Yellow alarms indicate active service provider contact is needed.

Maintenance Features:

Routine Cleaning: External surfaces should be cleaned with a damp cloth and mild cleaning solution. Circuit components and hoses require cleaning according to manufacturer recommendations. For disinfection, specific products like MikroZid® sensitive liquid from Schülke or Wip'Anil® from WILAmed are recommended.
Hygienic Reprocessing: Before patient change, the device requires wiping disinfection of the housing exterior, replacement of bacterial or HME filters, replacement or sterilization of reusable circuit systems, and a function check.
Servicing: Repairs and servicing must only be carried out by an authorized EOVE service representative or a qualified and certified service representative. Modifications to the EO-70 without manufacturer authorization are forbidden.
Maintenance Timetable:
- Every 1 year: Replace air filters.
- Every 2 years: Replace internal battery (or if service notification is displayed), replace silicone membranes and micro-pump.
- Every 20,000 hours of use: Replace turbine.
Battery Storage and Recharging: The internal battery should be recharged every 4 months maximum during storage periods (recommended 2 months) to maintain its health. For long-term storage, the battery charge level should be 100%, the device turned off, and the power cord removed.
