We propose a 3D printed #SplitterDevice.

The Graphenglass team has developed 3D Printed Circuit Splitter Device for Multiple Lung Ventilation for COVID-19 patients. Used to address the possible shortage of hospital Lung Ventilation devices, which is emerging as a concrete problem linked to the spread of COVID-19. All files are open source and they are shared in this website. Graphenglass has high reproduction's capacity by 3D printing and we are attending Hospitals needs altruistically.

Our purpose as a company has always been related to making a positive impact and tackle #GlobalChallenges through #Innovation and #Technology .

Our purpose leads us to solve this problem in cooperation with Catedra Industria 4.0 - Universitat Jaume I (Castelló - Spain) - and spanish #CoronavirusMaker Community in a open source mode, and only for extreme emergency.

3D Printed Circuit
Splitter Device for Multiple Patient Lung Ventilation

Reproducible by DLP / SLA / SLS / FDM

PLA seems to work better than PETG

The COVID-19 condition/SARS-CoV-2 virus
has resulted in widespread ventilator shortages.

This device enables multiple patients to be ventilated with the one anaesthesia machine or intensive care ventilator.

Formal laboratory testing is pending. It is designed to be compatible with the international standards for 22 mm breathing circuits, Anaesthetic and respiratory equipment - Conical connectors - Part 1: Cones and sockets (ISO 5356-1:2015)

It is accompanies a paper publication in ACADEMIC EMERGENCY MEDICINE 2006; 13:1246–1249 ª 2006 by the Society for Academic Emergency Medicine. This paper expose a pilot study that suggests significant potential for the expanded use of a single ventilator during cases of disaster surge involving multiple casualties with respiratory failure positively determine that a ventilator is available in an emergency department can quickly be modified to provide ventilation for several adults simultaneously.

As the premier North American organization for high-quality research and educational innovation in emergency care, the Society for Academic Emergency Medicine (SAEM) creates and promotes scientific discovery, advancement of education, and the highest professional and ethical standards for clinicians, educators, and researchers.

It is also accopanies with a paper from Comisión de Ingeniería Médica y Sanitaria del Colegio y la Asociación de Ingenieros Industriales de Madrid (Spain) - 21 march 2020 - Protocolo de Ventilación Múltiple con un solo ventilador para situaciones de Pandemia/Catástrofe Sanitaria, edited in view of the extremely serious situation of the epidemic crisis generated by the SARS-CoV-2 virus and the need to use technological resources in mechanical ventilation to attend to numerous patients in an environment of scarce resources, from the College they have proceeded to translate and revise the guide, published on March 20, 2020, by Erwan L'Her, head of the Intensive Medicine Service and resuscitation of the Hospital Center Regional University Morvan De Brest (France) for possible application in those hospitals that are necessary.

3D Printed Circuit Splitter Device for Multiple Patient Lung Ventilation HAS NOT BEEN TESTED ON A HUMAN

The consent for the patient and the procedure illustrated below refer to the laws of the Italian state, we do not know if they are also valid abroad. It is recommended to evaluate the eventually compliance of the device to the local laws

Authorization for the compassionate use of medical devices without CE marking for the intended purpose requested.

In exceptional cases of necessity and urgency, in the interest of protecting the health of an individual patient and in the absence of viable therapeutic alternatives, a medical device without CE marking for the proposed indication may be used for compassionate use.

The authorization of the Ministry of Health and the favorable opinion of the Ethics Committee are required for the compassionate use of a device.

Graphenglass makes no representations as to the suitability of this device for clinical practice and takes no responsibility for the misuse of this device. This device has not been tested or approved by any governmental organisations.

Document to be signed by the patient for the use of the device in an emergency situation:

El proyecto «DESARROLLO DE NANOCOMPUESTO CERÁMICO CON GRAFENO» INNCAD00/18/015" se ha terminado con éxito gracias al soporte recibido por la AGÈNCIA VALENCIANA DE LA INNOVACIÓ (AVI). El proyecto recibe una subvención de 118.237 €.

Project financed by:

Agència valenciana de la innovació
Proyecto IMAPEA/2019/19 – preparación propuesta H2020 SME Instrument fase I de Graphenglass

El objetivo del proyecto es desarrollar y comercializar una nueva categoría de material compuesto llamada Compact Graphene (CG). Nuestra tecnología patentada consiste en formulaciones específicas y métodos químicos para funcionalizar compuestos de polímeros + cerámicos con una pequeña adición de grafeno para generar un material disruptivo y rentable para el sector de la construcción con alto rendimiento técnico y capacidad industrial para producir increíbles celosías 3D.

El proyecto ha contado con la ayuda de IVACE dentro del Programa “PREPARACIÓN DE PROPUESTAS A H2020 (HORIZONTE-CV)” con una ayuda en forma de subvención de 5.625,00€. Esta actuación está cofinanciada por la Unión Europea a través del Programa Operativo FEDER de la Comunitat Valenciana 2014-2020.
