ViriMASK Protective Oculo-Respirator Scientists in Israel have designed a “protective oculo-respirator” that could be more efficient than an N95 (FFP2) mask while being more comfortable than a gas mask. Totally covering the nose, mouth and eyes (while air can penetrate around N95 masks), the   ViriMASK would use 0.1-micron filters while N95 masks would use 0.3-micron filters. The filters are multi-use and replaceable. According to the company, the ViriMASK provides the ultimate protection against small particles, viruses including the Covid-19, bacteria and aerosols. Its main advantage compared to N95 masks would be preventing the inhalation of viruses and conjunctional contamination. It is also easy to wash and disinfect.  This innovative respirator comes with a price however: on the company website, it costs between $20 and $30. http://emag.medicalexpo.com/covid-19-development-of-high-tech-protective-masks/

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....

Corona Mask A  surgical mask , also known as a  procedure mask ,  medical mask  or simply as a  face mask , is intended to be worn by health professionals  during  surgery  and during  nursing  to catch the  bacteria  shed in  liquid droplets  and  aerosol s from the wearer's mouth and nose. They are not designed to protect the wearer from inhaling airborne bacteria or  virus  particles and are less effective than  respirators , such as  N95  or  FFP masks , which provide better protection due to  their material.shape and tight seal .

The manufacturer of 3D printing materials Copper3D has just put online an open-source STL file of a N95 mask, which can be 3D printed and used against the COVID-19 virus. Its Hack The Pandemic initiative is global and aims to mobilize all manufacturers of machines, fablabs, printing services, etc. to create these masks quickly – the lack of which is a burden for hospitals and healthcare professionals. For some, it is difficult to be entirely reassured about the effectiveness of the mask called NanoHack, however, the company claims that many scientists are behind this project and that a patent application has been filed. Copper3D is a new player in the medical field, nevertheless the various products it has developed, including its antibacterial materials based on copper nanoparticles, do suggest that its solutions are effective. You can find on the  Cults  platform a STL file to print its protection mask against COVID-19. It can be 3D printed in  PLA  and with a...

 This is a type of mask that has a high possibility to prevent the person using the mask from getting the virus Nontoxic glue recommended, however glue is not really necessary, the mask can be used with any filter media. ideally electrostatic charged polypropylene. A 360 degree drum is unlimited to any given amount of layers needed for protection with a low rate of current and enough flow to breath comfortably. the inner drum should be spooled with cotton being the secondary buffer filter. Both drums are featured with hose clamping profiles to provide a reliable seal around the filter and to cradle the bounded rubber-bands. The reed valves are finished with a .5mm thick cutout of latex or silicone which would be installed with a small screw and washer. Last but not least the borders are to be lined with a soft neoprene stripping for a conformed seal around the face. CAUTION! if you are infected, this type of mask is unsafe for other people unless reed valves are plugged! ...

FILTER TECHNOLOGY BEHIND CAMBRIDGE MASKS As you can see from the diagram, Cambridge Masks filter air through three different layers. 1. The Primary Filter Layer The first layer of our mask filters out larger particles such as dust and PM10. The material is sublimation printed in different patterns to make the masks fashion friendly.  Dye-sublimation printing uses digital technology that works with polyester and polymer-coated substrates. Our unique sublimation dyes are transferred to special paper via liquid gel ink through piezoelectric print heads. Using heat and pressure the dye is then transferred into the fabric. The end result fuses the dye to the textile on a molecular level, meaning it cannot be removed from washing. When the dye is only applied to the surface of the textile or material to be printed, it can be removed from wear or washing, which we avoid this technique. 2. The Three-Ply Micro Particulate Layer The second layer of the mask blocks particu...

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.

Laryngoscopy is endoscopy of the larynx, a part of the throat. It is a medical procedure that is used to obtain a view, for example, of the vocal folds and the glottis. Laryngoscopy may be performed to facilitate tracheal intubation during general anaesthesia or cardiopulmonary resuscitation or for surgical procedures on the larynx or other parts of the upper tracheobronchial tree. Doctors sometimes use a small device to look into your throat and larynx, or voice box. This device is called a Laryngoscope. Use against COVID-19 Tracheal intubation should be performed by an experienced anesthesiologist with an experienced assistant (preferably also an anesthesiologist) and a nurse, to maximize patient safety ( fig. 1 ) and to manage the severe hypoxemia and circulatory failure that might occur. Muscle relaxants are highly recommended. 5    The video laryngoscope should be placed as soon as muscle relaxation is achieved, and tracheal intubation should be accomplished and conf...

3D Printed nasopharyngeal (NP) Test Swabs for COVID-19. The most common diagnostic test currently used for detecting the coronavirus in mucous samples is PCR, a polymerase chain reaction test that can detect nucleic acid from SARS-CoV-2 in respiratory specimens. In order to conduct this test nasopharyngeal (NP) test swabs are needed. There is a shortage of the nasopharyngeal (NP) swabs needed to collect samples for COVID-19 testing. These swabs are typically used for testing for influenza and other respiratory infections. The current and impending supply chain shortages are serious enough that clinicians are beginning to design and test their own swabs as quickly and safely as possible.   For example, a 3D Printed nasopharyngeal (NP) Test Swabs. M edically recognized SLA 3D printing systems and materials—commonly used in the dental industry—have been adapted to fulfill production of nasal swabs. The resin-based process offers high-resolution printing, which is needed for th...
