A mobile respirator has a respiratory device, a pipe, a breathing component, and a power bank. The pipe has two opposite ends respectively connected to the respiratory device and the breathing component, and the power bank is electrically connected to the respiratory device. A user can place the power bank and the respiratory device inside a backpack, and the pipe can be outstretched from the backpack. Thereby, the user can carry the backpack and wear the breathing component, so the user may breathe with assistance of the mobile respirator. By the power bank supplying electricity for the respiratory device, the mobile respirator is mobile outdoors and solves the trouble of dyspnea while exercising or staying outdoors.

In a facemask (100), atmospheric air is filtered by a disposable surgical mask (180) to form respirable air. The facemask (100) has a frame (150) formed with an interior cavity (151) for storing the respirable air to be breathed by the user. A thermoregulation unit (110) mounted to the frame (150) provides air conditioning to the respirable air by using a fan (421) to draw the respirable air from the cavity (151) to a heat exchanger (425) that contacts a thermoelectric module (410) to thermoelectrically transport heat to outside the frame (150), thereby cooling the drawn respirable air and condensing water vapor therein. The condensed water vapor is trapped by the heat exchanger (425). Cool and dry respirable air is released back to the cavity (151), thus providing thermal comfort to the user during breathing. A heat sink (432) contacted with the thermoelectric module (410) is used with a fan (431) to efficiently dissipate heat from the thermoelectric module (410) to outside the frame (150).

Systems, apparatuses, and methods for reducing temperatures of purified air from air-purifying respirators are provided.

A CPAP device for delivering pressurized, humidified breathable gas for a patient includes a flow generator configured to pressurize a flow of breathable gas. The flow generator includes an air outlet and a removable water container configured to humidify the pressurized breathable gas received from the flow generator. The water container includes an air inlet and an air outlet. The CPAP device further includes a first elastomeric face seal configured to sealingly abut against a substantially flat portion of the water container surrounding the water container air inlet, the first elastomeric face seal being located at an intermediate position between the flow generator air outlet and the water container air inlet when the water container is placed into position to pneumatically communicate with the flow generator. In addition, the CPAP device includes a second elastomeric face seal, a portion of which is configured to sealingly abut against a substantially flat external surface portion of the water container surrounding the water container air outlet.

A temperature-control device for heating and/or cooling gases or gas mixtures. The temperature-control device includes at least one air inlet, at least one air outlet and at least one vortex tube. The vortex tube(s) each have a vortex tube inlet, a hot air outlet and a cold air outlet. The at least one air inlet is connectable with at least one vortex tube inlet of the at least one vortex tube. The at least one air outlet can be connected at least in one flow direction with at least one hot air outlet and at least one cold air outlet of the vortex tube(s). At least one control element selectively adjusts the amount of air flow between the at least one hot air outlet and the at least one air outlet or between the at least one cold air outlet and the at least one air outlet.

A portable oxygen generating system is provided that comprises a reaction chamber, a feed system for providing and controlling hydrogen peroxide solution to the reaction chamber, and a cooling/condensing system for cooling the hot oxygen and water vapor leaving the reactor and condensing and removing water. The portable chemical oxygen generation system produces humidified, breathable oxygen, that is substantially free of hydrogen peroxide and other contaminants, at a controlled flow and temperature over an extended period of time.

A steam generator according to the present invention comprises a heat generating layer comprising an oxidizable metal, a carbon component, and water, a first water absorbent layer laminated on the heat generating layer and comprising a first water absorbent, a water absorbing sheet laminated on the first water absorbent layer, and a second water absorbent layer laminated on the water absorbing sheet and comprising a second water absorbent.

Introduced here is a face mask system having a mask enclosure that contains, or otherwise directly supports, an automated liquid-droplet dispensing mechanism (ADM) for humidification. In operation, the enclosure and ADM are compact and lightweight so that when worn by a user can be supported entirely by the user's head and neck. The enclosure can be comprised of one or more layers of breathable fabric adapted to flexibly conform to the face of a user when worn and form a cavity that is adjacent to the user's nostrils and mouth. The ADM can be comprised of a reservoir in which liquid is stored, a respiratory cycle detector, a timer and controller, and a droplet dispenser that controllably dispenses droplets of the liquid from the reservoir into the cavity for inhalation by the user.

A respirator includes a frame, a filter layer, and a face seal member. The frame has an outer side and an inner side. The frame defines an opening therethrough. The filter layer is mounted to the outer side of the frame and covers the opening of the frame. The filter layer is configured to prohibit permeation of aerosol, gas, and/or vapor contaminants therethrough. The face seal member is mounted to the inner side of the frame. The face seal member includes a seal contact area configured to engage a facial surface of a wearer. The face seal member incorporates a phase change material therein. The phase change material is configured to provide localized cooling by absorbing heat emitted by the wearer.
