The facial mask adjuster is designated by PEAK Sports for the urgent need of medical workers to improve comfort wearing protective masks for extended periods of time. The mask strap was originally produced using Farsoon FS3300PA material, but any equivalent material should be suitable. The medical safety goggle is designed and produced by Huaxiang Group. In China, thousands of pairs of products had been produced rapidly. The main goggle frames are produced from Farsoon FS3300PA material, the sealing rings are made of Lehvoss TPU material. Both designs are available on the Farsoon website. Suitable printing technologies are SLS, FDM and SLA.
ventilators and artifical respiration
2020-04-08 - Materialise has developed the Materialise NIP Connector, a device to convert standard equipment available in most hospitals, into a mask to facilitate breathing for patients by creating positive pressure in the lungs. These assembled masks allow clinicians to reduce the time patients need access to mechanical ventilators, which helps to reduce the strain on ventilator supplies. Materialise is now fast-tracking the regulatory registrations and expects to have the device broadly available for hospitals by mid-April.
The CoVent-19 Challenge has been launched on April 1, 2020 to design a rapidly deployable mechanical ventilator. The challenge which is hosted on the GrabCAD Challenges platform invites engineers, innovators, designers, and makers to create CAD assemblies by May 1 and functional prototypes by June 1, 2020 (Round 2: invitation only).
Munich Re and the Fraunhofer-Gesellschaft have launched the »Give a Breath - Challenge« to support the development of equipment for emergency ventilation in late March 2020. Individuals or teams can submit digital blueprints by April 6, 2020. The winning designs will be made available worldwide for decentralized production.
2020-03-26 - Researchers at RWTH Aachen University have developed a very simple do-it-yourself respiratory pump that is not certified. Among other things, a conventional resuscitator, 3D printed plastic parts, and an electric motor are required. According to the RWTH Aachen, the construction time is one day. Download the building instructions on the Coresponse project website.
2020-03-20 - In Spain, a 3D printed emergency respiration device has been developed and produced by the alliance of the Consorci de la Zona Franca, HP, Leitat, CatSalut, the Consorci Sanitari de Terrassa and the Hospital Parc Taulí de Sabadell. The device is a mechanical bag valve mask that can be used for short term emergency ventilation of COVID-19 patients.
On March 18th, Isinnova, an Italian start-up from Brescia, reported the delivery of 100 venturi valves for respirators to the hospital in Chiari in northern Italy within 2 days. The valves that connect the ventilator masks to the oxygen supply have to be replaced for each patient and were in short supply in the hospital. The original manufacturer could not procure replacements quickly enough. Due to the emergency situation, certification of the 3D-printed valves was waived. Although there were numerous requests from other hospitals afterwards, the 3D printed designs could not be made generally available due to legal and medical concerns. UPDATE 2020-03-27: Other 3D-printing-companies followed, such as Roboze which 3D printed hundreds of valves for respirators. Isinnova also developed a »Charlotte valve« that converts a Decathlon snorkel mask into a respirator. The use of the non-certified mask is dependent on patient consent. The design data can be downloaded from Isinnova's website.
The Medical goes Additive (MGA) working group has planned its regular meetings specifically as a 3D printing pandemic task force. The virtual meetings have been opened to non-members as well.
