A mask assembly includes a mask body configured to cover a wearer's nose and mouth. The mask body has a breathing area with breathing openings and a straw port. A replaceable filter medium is configured to cover the breathing openings on the interior of the mask body when installed thereon in a removable filter medium retainer element. A removable face plate overlies, and is spaced from, the breathing area on the exterior of the mask, so as to allow air to flow through the breathing openings and around the sides of the face plate, while blocking particulate matter from passage to or from the nose or mouth of the wearer. The face plate, the filter medium retainer element, and the filter medium may have openings that are alignable with the straw port.

A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.

A device for removably fastening to a protective headwear to more safely permit nourishment includes a ring-shaped body and a membrane. The body has an outer surface and defines an inner opening. The outer surface of the body is mountable about a hole in the protective headwear such that the inner opening of the body at least partially overlaps with the hole. A membrane is connected to the body to substantially close the inner opening. At least one slit in said membrane to permit passage of a utensil through the membrane.

A hydration system including a fluid reservoir, a fluid path in communication with the reservoir, and a magnetic quick connect interposed in the fluid path is disclosed. A fluid delivery system for a hydration system is also disclosed that includes a magnetic quick connect interposed in a fluid delivery path of the delivery system. The magnetic quick connect can also be used in a wide variety of fluid delivery systems. A kit for forming a fluid delivery system for a hydration system is also disclosed, as are various components of a hydration system.

The invention provides an equipment and a system that addresses the key concerns of eating/drinking in public while minimizing the chance of contamination of the eater and the public in general. The equipment can be a face mask, a face shield or a helmet that completely encloses at least the mouth and the nose of a person while providing intermittent access to the mouth without removal of the equipment. A mouth opening is provided on the equipment which is selectively blocked or unblocked by a covering element moved by a moving mechanism that moves the cover element to block or unblock the mouth opening. The mouth opening is selectively blocked or unblocked based on the distance between an activating element provided on a utensil or a wearable device and a receiving element provided on the equipment.

A portable hydration system and various components are disclosed. The system utilizes a pump to transfer potable liquid (e.g. water) from a liquid container to a user during challenging activities (e.g. endurance motorcycle riding).

A self-sterilizing, face mask, respirator, open or enclosed face shield employs germicidal, far UV-C light safe for direct human exposure, mitigating risk of acquisition or transmission of respiratory pathogens, such as COVID 19. Device attachments or special lenses direct far UV-C light into the respiratory chamber and/or reservoir areas of infection including nasal, oropharyngeal or ocular areas to reduce or eliminate pathogens, serving also as a treatment modality. In a preferred embodiment the face shield has a removable front section, which can be exchanged or replaced with sections that include various functional attributes while maintaining germicidal protections and avoiding need to remove PPE during these activities including consumption of liquids, oral medications or food, as well as providing antimicrobial absorbent sneeze or cough guard or rhinorrhea secretion absorption, or a communication device to address communication deficiencies caused by respiratory protection barriers.

A protective mask, including for use in medical and diagnostic procedures, is provide. The mask has a housing having an outer surface, an inner surface, a perimeter, and a securing member to secure the mask to the user. The housing may be made of a filtering material. A mask cavity is defined between the inner surface of the housing and a face of the user wearing the mask. The housing has an aperture providing access to the mask cavity. A port is positioned about the aperture in the housing. The port has a flexible portion with one of an open inlet with a bore to receive a probe adapted to be inserted into the mask cavity and a seal to seal access to the mask cavity when no probe is inserted therein.

An epidemic prevention mask having smoking and drinking functions is provided, which includes a first mask body and at least one hole-covering part. The first mask body is adapted to cover a mouth position and a nose position of a user, and has at least one through-hole corresponding to the mouth position. A hole-covering part is connected to a hole edge of the through-hole and covers the through-hole. The epidemic prevention mask of the invention can be worn as a general epidemic prevention mask, and also enables users to smoke or drink a beverage while wearing the epidemic prevention mask.

A breathing mask is provided. The breathing mask is secured around the head of the wearer and includes a nose lifter disposed on the front face of the breathing mask. The breathing mask includes a hood, a pair of eye goggles, a mouth aperture, and a check valve disposed on the rear lace of the hood. The eye goggles are affixed to the hood with an elastic band attached in the rear of the hood. Moreover, the mouth aperture is disposed on the front face of the hood below the nose filter. The hood is secured to the head of the wearer by a zipper disposed on the rear face of the hood and an elastic band encircling a pair of side faces and a rear face of the hood. The elastic band encircling the hood provides an airtight seal to protect the wearer from airborne diseases and other hazards.
