PROJECT: Invasive/Non-Invasive Ventilator
- Provide the software and algorithms for different breathing patterns (different sicknesses need different therapy profiles)
- Adapt to abnormal breathing events (mask leaks, coughing)
- Add a cost-efficient internal handpiece (by making it autoclavable)
HOW RBC ADDED VALUE:
By adding new electronics, mechanisms and software to the predicate ventilator, RBC created a new and improved combination invasive/non-invasive ventilation product.
RBC designed and developed the mechanical, electrical, and software for this improved ventilation product. We created the embedded grey nozzle, a complex electro-mechanical, autoclavable module.
With the “sidecar” enhancement, the invasive/non-invasive ventilator now includes these benefits:
- Patient adaptation: The invasive/non-invasive enhancement allows for quick patient adaptation to from invasive to non-invasive care.
- Cost containment: The invasive/non-invasive ventilator electro-mechanical control module is autoclavable for repeated use and cost containment.
- Single unit: Hospitals now have a single ventilator (since the functionality of two units were combined) to meet the changing therapeutic needs of adult and pediatric patients.
- Addressed leaks: When the hospital switches a patient to a non-invasive ventilation approach by using a face mask, the invasive/non-invasive ventilator can quickly adapt to the dynamics of possible mask leaks and active exhalation (coughing or patients fighting the ventilator).
- Added alarms: RBC also designed into the invasive/non-invasive ventilator an emergency ventilation mode (and alarms) to provide the same oxygen settings for a single limb until help can arrive.
- Ensured easy training: RBC designed the invasive/non-invasive ventilator GUI (Graphical User Interface) with the same look and feel as the previous ventilator to minimize training for the staff.
TECHNICAL AND DESIGN CHALLENGES
Creating a functional autoclavable module presented several challenges:
- Finding materials that could be autoclaved without cracking or warping.
- Designing the autoclavable electro-mechanical control module for easy user connection to the added control module and base unit.
- Developing effective software algorithms for the patient’s breathing response to adapt to mask leaks by the patients, coughs due to their illness, or the patient fighting the ventilator.
- Adhering to the appropriate FDA mandated alarms, RBC designed a ‘synchrony’ flow dynamics algorithm which adapts for the best respiratory care of critically ill patients.
By choosing RBC, the client’s engineering team was able to work on a different strategic initiative while we addressed this one.
