Librerespire Ventilator
For breath is life

An open source hardware initiative to tackle the mismatch of life saving medical devices.

The Need
for an open source ventilator

Medical ventilator shortage has been a critical issue throughout the world for decades. Ongoing Coronavirus disease 2019 (COVID-19) tested the limits and reiterated the need to look at the existing medical infrastructure. It showed the need to revamp the facilities to cater to the demands of excessive volumes of patients and the need to correct the mismatch of medical devices

More Details

Monitoring

There are multiple options to communicate with the ventilator. A touch screen, a laptop, or a mobile phone can be used to access the user interface and control the device. The main feature of the LibreRespire ventilator is the ability to act as a node in the Internet of Things (IoT), communicating via MQTT protocol. The system is capable of remote monitoring and remote control. The physicians can monitor and if needed even change the settings.

Alarms

To ensure patient safety during deteriorating clinical situations and inevitable device malfunction, the LibreRespire is equipped with multiple alarms and several fail-safe mechanisms. This will be further improved to meet the medical safety regulatory standards.

Modes

The system makes use of the existing compressed wall air and oxygen available within a hospital to minimize the mechanical complexity of the ventilator. Currently, the LibreRespire supports both volume control and pressure control modes so that the patient can be supported throughout the treatment process from intubation to weaning.

Overview

An Open source hardware initiative to tackle the mismatch of medical devices formed by an organized group of professionals from multiple disciplines focused on developing an affordable, medical grade, robust, open source solution to acute shortage of mechanical ventilators due to COVID-19 pandemic. We have a core developer group collaborating online from different parts of the world, to design, build, test and validate the prototype.

The Need

Medical ventilator shortage has been a critical issue throughout the world for decades. Ongoing Coronavirus disease 2019 (COVID-19) tested the limits and reiterated the need to look at the existing medical infrastructure. It showed the need to revamp the facilities to cater to the demands of excessive volumes of patients and the need to correct the mismatch of medical devices

Objectives

  • Design an open source, simple but robust medical ventilator.
  • Promote a medical hardware device industry based on the principles of openess and transparency.
  • Put the patient at the center of reaserch and developement.

How it works (demo)



Based on Computational fluid dynamics (CFD)



Collaborations

We are currently working with the following accademic institutions

Trinity College, Dublin

Trinity college provided expertise in computational fluid dynamics (CFD) to improve the flowmeter and flow-mixer designs, with the generous support of COVID-19 response grant.

Malmö University, Sweden

Malmö University is supporting with optimizing the device for 3D printing and expertise on device design.

LibreLabs Foundation

LibreLabs foundation is a platform inspired by the need to develop new open source technologies to rectify the mismatch of medical devices. It is based on the WHO principle of “4 As” Availability, Accessibility, Appropriateness, and Affordability. LibreRespire is the second project of LibreLabs foundation.
