Wearing a face mask or a filtering facepiece respirator, especially in hot weather for more than one hour, causes discomfort. But, in a viral pandemic, a barrier to filter inhaled and exhaled air is necessary to protect against airborne pathogens. The sensations of heat abstraction, that is, coolness and cold, can be captured by the rational design of optimized molecules called TRPM8 receptor agonists. The topical application of these molecules alleviates the discomfort of wearing a face mask covering. Several entities were identified by synthesis and experiment as having the ideal properties for achieving this purpose. The preferred embodiments are certain 1-diisopropyl-phosphinoyl-alkanes described as DIPA-1-5, DIPA-1-6, DIPA-1-7, DIPA-1-8, and DIPA-1-9, collectively referred to herein as “DIPA compounds.” The applicant found that topical delivery of DIPA compounds to the facial skin, especially to the surface of the nares (nostrils), alleviates face mask discomfort. From these studies, it is hypothesized that it is the absence of cool air dynamics about the nostrils that causes face mask discomfort. The present discovery pertains to pharmaceutical compositions that relieve face mask discomfort.

A breathable biological face covering comprising a fabric material and an anti-pathogen substance on the fabric material. The anti-pathogen substance comprises a lactoferrin protein. The amount of lactoferrin protein on the fabric material may be in the range of 0.6-1.5 grams/m2 of fabric material. Another embodiment is a lactoferrin composition comprising an aqueous fluid at pH<7.0 and lactoferrin protein mixed in the aqueous fluid at a concentration of 0.6-1.5 grams per liter. This lactoferrin composition may be administered into the respiratory tract. This composition could be useful against respiratory microbial pathogen, such as influenza virus or coronavirus.

The novel and improved face mask materials with inherent virucidal activity not onlyreduces/nullifies the viral load via inhalation, but reduces the transmission from both the inhalation and contact routes by contributing to good hygienic practice thus reducing the impact of asymptomatic carriers and patients with low-grade disease in the community. This prevents the possibility for re-inhalation of carbon dioxide-rich air and gives comfort to the wearer. Variable enhancement of the virucidal, filtration and hydrophobic activities across multiple layers are achieved to suit different cohorts within the general populace as well asthe Healthcare system afflicted by the COVID-19 pandemic. Uniquely different types of face masks are custom-made with suitable degrees of enhancement of outer, middle and inner layers for different requirements of specified end-user populations utilizing commonly available, low-cost material. In addition to the above advantages, the present invention is fabricated of biodegradable materials at the same time it can be washed several times afterusage making it cost effective. It is also constructed in way that it can fit the face of the wearer perfectly without any spaces in-between. Further applications for this unique invention, combining nano-filtration with virucidal properties via use of nanotechnologyincludes, advanced filtration of artificial ventilator machines, air-purifiers, air-conditionerfiltration systems and Health care system usage as in bedding, scrub suits, clothing, etc. Theuse of germicidal properties would complement measures usually practiced for seasonalinfluenza and should also be considered for other diseases transmitted via inhalation route.

Embodiments described herein provide systems and methods for protecting doctors and others from pathogenic microorganisms aerosolized during surgical and other procedures on patients. The systems and methods generally operate by forming a partially-enclosed chamber around the patient's face during the procedure. A facial adapter and facial shield isolate a portion of the patient's face from the surrounding environment. The partially-enclosed chamber is connected to a vacuum source that brings the pathogenic particles through a filter, which further decreases the number of pathogenic particles expelled into the environment.
