A personal protection system for providing a sterile barrier around medical/surgical personnel. The system includes a helmet over which a hood or a toga suspended. The helmet has a chin bar that extends forward of the face of the individual wearing the system. At least one manually actuated control for regulating one aspect of operation of the system is mounted to the chin bar. Sometimes the control is a button that is depressed to control the operation of a helmet mounted fan that draws air into the hood or toga. A microphone may also be mounted to the chin bar.

The system comprises a cooling garment that is intended to cool the user of the garment. In one embodiment, the cooling garment is worn under a body armor. In one embodiment, the cooling garment is worn under any other garment or in any situation or environment where the user desires a cooling effect. In one embodiment the cooling garment comprises an outer layer and an inner layer. The inner layer has a plurality of perforations that allow air to flow therethrough. The outer layer is solid, so that air is urged toward the perforations and does not exit the garment away from the user, but instead towards the user. A flexible hose is coupled between the first and second layer and extends outward from the garment. The hose terminates in a quick release coupling that allows it to be removably attached to an air source, such as from a pump or other cooling system. In one embodiment, the quick release coupling is magnetic and is detached by pulling on the coupling or by the user of the cooling garment stepping away from the connection. In one embodiment, the system is used in a vehicle with a pump coupled to the electrical system of the vehicle.

A protective apparel support system is disclosed comprising a support frame configured to rest on the shoulders of a wearer, the support having a first shoulder member, a second shoulder member and a shield engagement portion. A shield is selectively coupleable to the support and protective apparel is coupled to the shield.

A non-inflating flexible warm air distribution manifold that attaches to the patient side of patient gown. This manifold is configured to receive warmed air the of the warm-air receiving orifice and to distribute the warm air over a wide area of the patient side of the gown. By one approach the manifold comprises a flexible baffle. This baffle can be disposed on the patient side of the gown office proximal (in fact, opposite) the warm-air receiving orifice. The baffle has two or more sides that are secured to the gown and two or more sides that are not secured to the gown. Warm air entering the gown through the warm-air receiving orifice can readily pass through the sides that are not secured to the gown while the warm air entering the gown is largely impeded from passing through the sides that are secured to the gown.

A ventilated garment is configured to be supported on a wearer to provide ventilation to a body part of the wearer. The garment can include an air flow guide that is defined by inner and outer panels. A blower is positioned in the air flow guide to draw air in through an intake and discharge the air through an outlet of the guide. The guide can be arranged on the garment so the intake is adjacent the base of the back of the wearer and the outlet is adjacent the neck. The garment can include a support cushion in operative alignment with the blower to cushion the body part from the blower when the blower is pressed between the body part and a support surface.

The present invention discloses an intelligent control system and method for a doll clothing cooling device, the system including an information acquisition system, an image acquisition system, a computer vision system, and a central control system. The information acquisition system acquires environmental parameters and human physiological parameters in the mannequin garment. The image acquisition system acquires a video image of a human face and transmits it to the computer vision system to calculate a human head temperature. The central control system predicts the human thermal sensation data based on the acquired environmental and physiological parameters. The opening degree of the cooling device of the mannequin garment is automatically adjusted according to the human body heat sensation data and the voice instructions of the wearer of the mannequin garment. The invention solves the problem of dynamically improving the thermal comfort of the wearer of the mannequin costume in real time.

An example face shield includes a face shield lens comprising a locking channel, a face shield shell configured to receive the face shield lens when the face shield is inserted into the face shield shell, and a lens lock configured to move between: a locked position in which the lens lock is configured to engage the locking channel of the face shield to secure the face shield lens to the face shield shell; and an unlocked position in which the lens lock is configured to disengage the locking channel of the face shield to permit insertion of the face shield to the face shield shell and removal of the face shield from the face shield shell.

A wearable garment, such as a vest, for providing thermal conditioning, for example cooling and/or heating, to a user. The vest may be used with cryogenic temperatures. Peltier devices, pre-charged nitrogen canisters, or miniature Stirling cryocoolers may be mounted and built into the wearable or externally carried or mounted thereto. A pump, such as a vacuum diaphragm pump, causes thermally conditioned air to flow through a series of porous regenerative tubing and/or porous panels to supply conditioned air to a user of the garment. The system may use a cryocooler having a pulsating cold finger. The cryo embodiments may supply ?200? C. gas through the panels or tubing. Portable systems can be carried or attached, such as HVAC, refrigeration, heating or the like. Control systems may regulate the temperature and may be adjusted by a user, for example using an input pad or a mobile device.

An article of outerwear which resists ignition and insulates against heat, the article of outerwear has a plurality of sections made from a fabric, such as woven fabric, knit fabric or a combination thereof. The plurality of sections allow the article of outerwear to stretch enhancing the comfort of the wearer of the article of outerwear. The outerwear may include a protective shroud/hood which has fans to circulate air inside the protective shroud/hood, the fans having air intake openings and vent openings, the air intake openings opening in planes which are perpendicular to planes in which the vent openings open.

A cleanroom coverall includes a coverall suit and a ventilator positioned inside the coverall suit. The ventilator is fluidly connected to the ambient of the coverall, such that between the ambient of the coverall suit and the ventilator, a one-way valve is present which is situated upstream the ventilator and which one-way valve opens when the ventilator is active.
