During national crisis as virus pandemics, bio-terrorism, chemical pollution, a response is to lock down all the economy, with several % GDP loss, or to convince population to wear, reasonably, appropriate individual anti-virus and bacterial protection accessories, made of a full head and shoulders protection mask, equipped with air ventilation and processing unit, and gloves, and body protection foil, for single or multiple use, and get minimal economic losses. The air processing unit may be developed a modular structure, starting from a simple filtered fan, with air suction on top of the head, flowing air over the face, for low probability of contamination environments, upgraded to a more complex unit including heat pipe, catalytic organic matter reduction, oxygen generator and closed circuit breathing unit, that may be integrated into a full body personal protection equipment by extending the functions of temperature, humidity and pressure control to full body, for hazardous environments.

A mask includes a support member that is configured to extend across at least a portion of a face of a user and a heater connected to the support member.

A system for thermal regulation of a nebulizer is provided that is structured to deliver a chilled mist to the snout, muzzle, beak, or trunk of an animal. The system includes a container to house a nebulizer and a thermal material together and a mask to deliver the chilled mist to an animal. The thermal material acts to chill a liquid located inside the nebulizer in order to deliver a chilled mist to the animal for therapeutic purposes, such as initiating therapeutic hypothermia, or treating various respiratory illnesses such as croup, laryngobronchitis, and smoke inhalation.

A portable device designed to heat the cold air that is inhaled through a person's nose is revealed, thus protecting respiratory function in adverse climates, especially for those suffering from lung diseases and the like, or for those who are susceptible or at risk of acquiring these diseases due to their age or work and need a protection mechanism. This device is composed of a support system and an energy system, wherein the support system guarantees the stability of the device next to the nose of the user, while the energy system heats the air that the user inhales through the nose and allows the user to regulate the temperature of the heat sink located near the nose by means of a control knob.

Disclosed is a high-temperature virus-killing mask, including a sunhat, a heating component and a mask body. A high-temperature microtube with a resistance wire is arranged in the sunhat. The resistance wire may be energized to generate heat to enable the temperature in the high-temperature microtube to rise up to about 200° C., so that, when a user inhales air, the NCP in air flowing through the high-temperature microtube will be killed by the high temperature.

A face mask apparatus is formed with a breathing chamber that provides adjustable warm and humidified air for inhalation. The breathing chamber heats cold air that is breathed in through the face mask during normal breathing, which is worn over the nose and mouth of a person. A temperature gauge monitors temperature for future adjustment of the amount of heat generating current. The air in the chamber is heated for inhalation by a resistive carbon fiber tape. The temperature of the resistive material (and by extension the warm air generated), is regulated/adjusted by increasing or decreasing the current output settings on the power source. Warm and humidified air is produced. The face mask may be part of a balaclava hood or a hat, or to other head gear, or as a stand-alone with straps around the head, optionally with an adjustable solar powered battery.

A system for thermal regulation of a nebulizer is provided. The system includes a container to house a nebulizer and a thermal material together. The thermal material acts to chill a liquid located inside the nebulizer in order to deliver a chilled mist to a patient for therapeutic purposes, such as initiating therapeutic hypothermia, or treating various respiratory illnesses such as croup, laryngobronchitis, and smoke inhalation.

A cooling element (100) for use within a cooling device (600) of a closed-circuit respirator (690), includes a plate shaped cooling element housings (110, 120), each with a respective liquid-tight closure (112, 122) filled or to be filled with a coolant (211). The cooling element housings (110, 120) each have a plate outer wall (114, 124) and a plate inner wall (116, 126) arched in the direction of the plate outer wall, which form, together with additional side walls (115, 125), cooling element volumes (118, 128) for the coolant. The plate shape cooling housings can be fastened or are fastened to each other such that the one plate inner wall and another plate inner wall are located opposite each other and are arched away from one another.

A cooling element system (100), for use within a cooling device (590) of a closed-circuit respirator (691), includes a plurality of cooling elements and a collar (120). The cooling elements each have an element housing (112), having a liquid-tight closure (114), filled or fillable with a coolant. The element housings allow for a common mounting arrangement of the number of cooling elements within the cooling device. The collar encloses the cooling elements in the common mounting arrangement and has a carrying area (122), which is configured to carry the number of cooling elements in the common mounting arrangement at the carrying area. A removal of the number of cooling elements, in the common mounting arrangement, from the cooling device and an insertion into the cooling device, are possible by means of the carrying area.

A self-contained functional and physical architecture is described to utilize a honeycomb configuration Positive Temperature Coefficient semiconductor thermistor heater to provide breathable warm air to an individual under cold weather conditions. The high-temperature of the heater element provides substantial efficiency allowing hours long use on battery power only. The invention utilizes pulsed heater operation in combination with lengthwise air mixing to rapidly and efficiently lower the temperature of the high temperature heated air to a temperature that is breathable. The invention solves issues with visor fogging, adaptability to a wide temperature range, and adaptability to a wide range of individual exertion. This system is applicable to a wide range of cold weather work environments, cold weather sports, scientific exploration, military operations, or medical needs. Several physical embodiments are described utilizing various forms of helmets and masks.
