A gas-supplying mouth mask includes: a mask body for leaning against a user's nose to development of a semi-open space between the mask body and the user's face, wherein the mask body comprising a breathable structure and an airtight structure; and a gas generation unit placed in the mask body for generation of functional gases which can be released to around the user's nose through the breathable structure. Based on the above structures, the gas-supplying mouth mask encircles the functional gases inside the semi-open space formed by the mask body and the user's face and causes a better utilization rate of functional gases.

A headgear is described that includes an air purifier, a microphone, and a control unit. The control unit analyses a signal output by the microphone to determine a magnitude of wind. The control unit then controls a flow rate of the air purifier in response to the determined magnitude.

A personal protected-air system includes a ring adapted to fit over a user's head. The ring includes a port for receiving breathable air, a manifold in fluid communication with the port, and vents in fluid communication with the manifold. The vents are distributed about a portion of the ring. A face mask is coupled to the ring. The face mask has a first edge, a second edge, and mask material extending from the first edge to the second edge. The first edge is coupled to the ring adjacent to the portion thereof where the vents are so-distributed. The second edge is adapted to fit snugly against the user's cheeks and nose bridge wherein the mask material is spaced apart from the user's nostrils and mouth by an air space and wherein the breathable air enters the air space via the vents

A personal protection system for providing a sterile barrier around medical/surgical personnel. The system may include a head unit over which surgical garment such as a hood or a toga may be suspended over. The surgical garment may include a sterile material and a shield configured to be disposed in front of the wearers face when disposed over the head unit. The shield may comprise an anti-reflective coating configured to reduce the glare observed by the individual through said shield. The head unit may comprises a light assembly that is disposed on the wearers side of the surgical garment, and an inner surface of said surgical garment may comprise a light reflective material configured to reduce the amount of light emitted from said light assembly that is reflected back toward the individual.

A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

A wearable air purifier includes a headgear, an air purifier assembly, and a nozzle assembly. The air purifier assembly includes a filter and an airflow generator for generating an airflow through the filter. The nozzle assembly includes an inlet aperture configured to receive a filtered airflow from the air purifier assembly, and an air outlet for emitting the filtered airflow from the nozzle assembly. The nozzle assembly includes a first end section connected to the headgear, a second end section connected to the headgear, and a midsection connected to the first end section by a first hinge and connected to the second end section by a second hinge.

A device is designed in the form of glasses with a frame (10) having a frontal portion (20), temporal portions (30) abutting the frontal portion on two sides, and temples (40) attached to the temporal portions. Each temporal portion (30) comprises an intake fan (31) with an air filter (50) and a discharge air duct (60), wherein nozzles (63) of the two air ducts (60) are oriented towards one another, providing the formation of substantially counter-directed streams of clean air directly under the nostrils of a user, with the result that a region of high pressure is formed, keeping non-purified ambient air from entering the nostrils.

A headpiece (1) worn by a user provides air to the user from which airborne disease particles have been removed. The headpiece includes an air guide (2) through which air flows due to fans (13, 14). Antibacterial and/or antiviral devices (3) such as filters and ultraviolet (UV) disinfecting lights operate as air purifiers to purify air that passes through the air guide. The purified air is delivered to an area between the inside surface of a visor (10) and a face (11) of the person wearing the headpiece.

A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.

A pump system (120) has a central pump unit (110), with which at least one hook-up unit (130). The least one hook-up unit (130) is from a group of a plurality of hook-up units (130) that can be combined in modular form for setting an operating point of a pump (10) that forms the pump unit (110). A method uses such a hook-up unit (130) in a pump system (120) for setting an operating point of the pump unit (110) thereof. A medical device is provided with such a pump unit (110) or with such a pump unit (110) and at least one hook-up unit (130) combined with the pump unit (110).
