Continuous positive airway pressure

Continuous positive airway pressure (CPAP) is a form of positive airway pressure ventilator, which applies mild air pressure on a continuous basis. It keeps the airways continuously open in people who are able to breathe spontaneously on their own, but need help keeping their airway unobstructed. It is an alternative to positive end-expiratory pressure (PEEP). Both modalities stent the lungs' alveoli open and thus recruit more of the lung's surface area for ventilation, but, while PEEP refers to devices that impose positive pressure only at the end of the exhalation, CPAP devices apply continuous positive airway pressure throughout the breathing cycle. Thus, the ventilator itself does not cycle during CPAP, no additional pressure above the level of CPAP is provided, and patients must initiate all of their breaths.^[1]

Ventilaid breathing device Mk III

VentilAid is a very simple, yet effective device for non-invasive ventilation. It is especially projected to help patients suffering from COVID-19. VentilAid helps breathing, prevents alveoli from collapsing and monitors patients health. Major features Compactness and mobility Universal power supply Automatic function in CPAP and BiPAP modes FiO2 do 70%, Up to 70% FiO2 Pressure up to 15 cm H2O (wi th a greater technical capablity of up to 30cm H2O) The device adapts to the breathing rhythm of the patient https://www.ventilaid.org/ventilaid-breathing-device-mk-iii/

New ventilator mask protects entire face from coronavirus

https://www.israel21c.org/new-ventilator-mask-protects-entire-face-from-coronavirus/ Many people are wearing facemasks to avoid breathing airborne coronavirus particles, and to keep from touching their noses and mouths. However, even N95 masks can’t fully block tiny virus particles and can’t kill the virus (two masks under development in Israel aim to do that). Any blocked viral particles stay on the mask’s surface and pose a hazard when handled and thrown away. Furthermore, facemasks don’t cover eyes. Although the nose is the main route for coronavirus into the lungs, some researchers believe the eye’s conjunctiva is another possible point of entry. That’s why Israeli physician and serial medical-device inventor Dr. Noam Gavriely worked quickly to develop what he calls the ViriMASK Protective Oculo-Respirator . ViriMASK is strapped around the head, covering the eyes with a see-through visor and the nose and mouth with a filtering mechanism....

Mask Strap Efficiency This simple but useful tool is designed to make face masks less painful to wear for medical workers treating coronavirus patients. The part is made by printing a set, and then connecting with any filament which will also set its width. In this way, the filament which is needed for a single print is reduced and 18 sets on a 250x250mm print bed are allowed. Small protrusions on both sides of the plastic buckle hold the mask strap and the mask strap does not exert painful pressure on the ears. References: Michael B. ( 2020 ). Prusa Printers.
