The Ultimate Ventilator To Save COVID-19 Patient Lives

System Modes

The system functions in three discrete modes:

In Pressure Control mode, the system will provide steady inspiratory pressure and constant respiratory rate and duration, with a variable tidal volume, dependent on patient lung compliance and airway resistance.

When set to Volume Control mode, the system will provide constant tidal volume, rate and duration, with variable pressure.

When set to Pressure Support mode, the system will generate constant pressure and respiratory duration, while the respiratory rate will be determined by the patient via autonomous respiration, with a resulting respiratory volume. In each of the ventilation modes, PEEP pressure will be maintained in the lungs after each breath, and the oxygen content in the mixture will be set by the attendant.

The Ultimate Ventilator To Save COVID-19 Patient Lives

System Objective

The system offer 4 discrete modes of ventilation:

In Pressure Control Ventilation (PCV) mode, the system provides fixed inspiratory pressure and constant respiratory rate and duration, with tidal volume which is a function of physical characteristics, such as patient lung compliance and airway resistance. .

In Pressure Regulated Volume Control (PRVC) mode, the system provides constant tidal volume, rate and duration, with variable pressure. .

In Pressure Support (PS) mode, the system delivers fixed inspiratory pressure and respiratory duration, with respiratory rate determined by the patient’s autonomous respiration. A backup respiratory rate can also be set, which provides mandatory breaths if the patient fails to breath autonomously within a time limit. A pressure-based trigger can be set for autonomous breathing, with negative or positive pressure values.

In Continuous Positive Airway Pressure (CPAP) mode the system required the use of a CPAP mask with a single-limb breathing circuit. In each of the ventilation modes, PEEP pressure will be maintained in the lungs after each breath, and the oxygen content of the mixture will be set by the attendant.

System Overview

The system is comprised of 4 main units:
Central control unit –Contains a programmable-logic controller, touch-screen human-machine interface, two inlet valves (oxygen and air), and sensors which enable measurement of pressure, air flow and oxygen content. This unit acts as both a main control hub and a user interface for the system.
Mixing bag – Serves as pressure reservoir and mixing tank. It stores the mixture with the required oxygen content and pressure before delivery to the patient, dampening positive and negative pressure shocks (functioning as a pneumatic capacitor of sorts).
Patient unit – Contains the inspiratory and expiratory valves, an intrapulmonary pressure sensor and 22 mm connectors, for connecting a dual limb breathing circuit to the endotracheal tube. To be placed on the patient’s bed, by the head.
Flexible tubing – Connects the main control unit to the chest unit, and the main control unit to the mixing bag.

Our Story

Our story begins with the global COVID-19 outbreak, and the understanding that one of the biggest threats humanity is facing is severe illness caused by the virus attacking the lungs, to the point of respiratory failure. This may force hospitals and geriatric institutions underequipped with ventilators to choose whom to ventilate and whom to leave for dead. This reality has produced numerous attempts at finding quick solutions to the pandemic, such as products based on automating manual ventilators, or alternatives for CPAP or BPAP ventilators. However, it was clear to us that these will not suffice and in some cases may even cause harm, and that a better solution is required.

Our team, composed of aeronautic, mechanical and systems engineers, whose day jobs are working on classified defense contracts, have decided to rise to the occasion, working around the clock and under the radar to develop a semi-professional ventilator.

The criteria selected were rapid development, production scalability, reasonable cost, meeting the strictest standards and most of all – that any one of us would feel safe using the device on a family member if, heaven forbid, they would require a ventilator.

The team was joined by medical experts specializing in emergency, trauma and respiratory medicine, who have treated corona patients. They accompanied the process and provided their experience and guidance regarding the exact specifications for the device.

We’ve spared no expense in the design and construction of the device, from sensors to regulators to every other component, meeting the strictest standards in aviation and medical devices.

We have fully covered the development costs ourselves, out of faith in our abilities, and we have no intention of profiteering off the sale of these devices.

We seek to produce and deliver these devices nationwide indiscriminately, saving lives regardless of ethnicity, religion, politics or social standing.
