3D Printed nasopharyngeal (NP) Test Swabs

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. Medically 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 the fine components, while bio-compatible materials that have already undergone certification for dental applications can be used right away.

NP swabs overview:

NP swabs are flexible sticks with a bristled end that are inserted into the nose to the back of the nasal cavity and swept around to collect material that sticks to or wicks up the bristles. The swab is then placed into a vial that contains a culture medium. Swab sticks have an intentionally weak point 7–8 cm from the bristled tip, which allows the stick to be broken to the correct length so that the vial can be capped before it is transported to a laboratory for testing.

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....

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/

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.
