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 method and apparatus is disclosed for constructing a mask. The mask is formed of a first mask segment overlayed on a second mask segment. The first mask segment has an article cutout on a right side. The second mask segment has an article cutout on a left side. The article cutouts extend toward a center of the mask. The mask segments are coupled together such that a passage extends between the mask segments and between the article cutouts. A user who is wearing the mask may pull either or both of the article cutouts across the center of the mask to create a hole for entrance of an article. When released, the hole may close or may enclose around an article extending through the hole.

Illustrated views of an exemplary face mask for protecting people from spreading infectious diseases and to allow an opening to speak, eat, talk, etc. is presented. The face mask is useful for allowing a mouth and a nose of a person to be exposed or covered without removing the face mask. The opening of the face mask is useful for the person to eat, drink, talk on the phone, to talk in conversation when socially distant, etc.

A contaminate shield for protecting dentists and patients from harmful emissions during dental procedures is disclosed. The contaminate shield can include apertures allowing the dentist to access the patient's mouth through the contaminate shield. Further, the contaminate shield can include an aperture connectable to an air exchange system that provides clean air to the patient or removes contaminated air expelled by the patient. Additionally, the contaminate shield can be secured to the patient's face such that it covers the patient's nose and mouth to provide a physical barrier between the patient and a dentist.

A protective face mask is provided. The protective face mask may have a removable mouth panel (or “apron”) which acts as a protective personal barrier for the user. The removable mouth panel is suitable for allowing quick access to the user's mouth to, for example, eat and/or drink without needing to remove the entire body of the mask. Further, the user's nostrils remain secured and protected beneath the remainder of the mask. The mouth panel may also be completely disconnected from the main body of the face mask to allow a user to eat and/or drink. Alternatively, the mouth panel may be partially disconnected from the mask by being rotated to the left, to the right or upward to allow a user to eat and/or drink.

Provided are a mask device and a method for controlling the same. The mask device includes a mask body configured to cover a nose and mouth of a user, a first air cleaner connected to one side of the mask body, and a second air cleaner connected to the other side of the mask body. Also, the mask device includes a first suction fan module installed in the first air cleaner, a second suction fan module installed in the second air cleaner, and an exhaust fan module disposed in the mask body.

A face mask having plurality of closeable flaps which includes a mask body having a pair of ear loops extending therefrom as well as a first flap member and a second flap member integrated therewith. The first flap member extends across a central portion of the mask body and can be moved between a closed position and an open position. The second flap member is positioned within the first flap member and can be moved between a closed position and an open position. Through the action of the first flap member and the second flap member, a large opening or a small opening can be selectively formed in the mask body while the face mask having plurality of closeable flaps remains in place on a wearer.

The present invention relates to a mask provided with a cover that is easily opened or closed when a user drinks or eats, and relates to a mask including a body made of a transparent material and a cover formed integrally with the body and capable of preventing interference with the body, when the cover is opened or closed, by a through-hole formed at an upper portion of the cover.

A multifunctional protective mask with sucking and whistling includes a mask body, a slit and a fixing section. The mask body includes folded first wrinkle and second wrinkle, and a splicing section formed at the junction of the first wrinkle and the second wrinkle. The slit is located between the second wrinkle and the splicing section. The fixing section fixes the first wrinkle, the splicing section and the second wrinkle. Therefore, the present invention can provide the user with many functions such as the convenience of inhaling tea, coffee, beverages, nasogastric tube feeding or whistling while wearing. At the same time, the mask has good bacterial and virus filtration efficiency (PFE/BFE) and closeness. The invention can be automatically produced, has a short process time, has many advantages such as low cost, easy commercialization and mass production, and benefits the society.
