Mechanical respirator

This invention describes a mechanical ventilator that mixes oxygen with compressed air to deliver a controlled gas mixture to a patient. The system uses a fluid flow controller, which in one specific version, is based on a bag-valve-mask (BVM) that is automatically squeezed by a pneumatic actuator. It also includes components for precise pressure regulation, particularly for maintaining PEEP (Positive End-Expiratory Pressure).

Why it matters: Filed during the pandemic, when rapid, simpler ventilator solutions were sought. Advances in embedded systems and sensor integration since 2021 could make the precise pneumatic control and calculation means for a reliable, automated BVM ventilator more robust and easier to implement.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedProcessor, pneumatic control, medical-grade components.
