A system and method for maintaining, monitoring and improving air quality and purity in a room or environment, such as a hospital room or operating room.

Disclosed herein are modules for performing hyperbaric oxygen therapy (“HBOT”) on a patient submerged in pressurized water where substantially no gas is present in the module. The modules generally have an entry, a fluid inlet for introducing water into the module, first and second fluid outlets positioned substantially at a base and a top of the module respectively, and a utilities inlet and outlet in part for transferring breathing air to and from the patient. The module permits HBOT treatment on a patient submerged in water with no air in the module, thus reducing the risk of fire or explosion. Methods and systems are also contemplated. Disclosed herein are methods of filling a module with water until there is substantially no gas in the module, and providing the patient in the module with treatment air during HBOT treatment.

The dry-immersion bed of the present invention is suitable for intensive care units (ICUs) and fulfills the function of providing treatment for diseases such as capillary leak syndrome. The dry immersion bed fulfills the function of recovering cardiovascular physiology by normalizing the systemic distribution of water, albumin and electrolytes, and improving lymphatic drainage, venous return, cardiac output, cell metabolism and immunity.

An access control apparatus having a protective covering configure to cover at least one of a subject or an object inside said protective covering is provided, where an opening is configured to provide access to the at least one of a subject or an object and a covering element configured to selectively cover said opening. A receiving element is provided on the protective covering and an activating device with an activating element is provided external to the protective covering. A motor is coupled to the covering element, wherein said motor selectively moves the covering element to at least partially unblock the opening based on a wireless activation signal and a distance between the activating element and the receiving element being within a predefined distance and to completely block the opening based on the wireless activation signal and the distance between the activating element and the receiving element being greater than the predefined distance, effectively limiting the exchange of contaminated or adverse environments between an internal area of the protective covering and an area outside the protective covering. The covering element can be an integral covering or an iris diaphragm arrangement.

Provided is a clean booth in an assembled state, including: a frame; a wall portion that is provided on the frame and forms an internal space; a first unit that is provided on the wall portion and includes a first fan that supplies air to the internal space via a first filter; and a second unit that is provided on the wall portion and includes a second fan that exhausts the air in the internal space.

An air adjusting device includes a casing, a hood, a first airflow generating unit, a tunnel and an air conditioning module. The hood has a wind inlet. The first airflow generating unit is connected to the hood. The tunnel is connected to the first airflow generating unit, wherein the tunnel has a wind outlet. The hood, the first airflow generating unit and the tunnel form an airflow passage. The airflow passage is isolated from an internal space of the casing. At least one part of the air conditioning module is disposed at the wind inlet. The first airflow generating unit draws a first ambient air into the airflow passage from the wind inlet. A temperature of the first ambient air is adjusted by the air conditioning module and discharged from the wind outlet through the airflow passage.

A negative pressure respiratory treatment hood for human medical patients. A rigid hood, preferably of unitary fabrication from a clear material, is positioned over the patient's head. The patient's body extends out of an opening in a front wall of the hood. A hinged door may be attached to the front wall of the hood, and is closed and partially closes the opening, and a shroud is sealing connected to the hood and is draped over the patient so as to form a pressure seal. A negative pressure source is connected to the hood and forms a negative pressure environment around the patient's head. Access openings have a resilient material across them, with small openings in the resilient material, to permit access to the patient by medical personnel and/or medical equipment.

A portable isolation unit for use with a bed or chair, including an enclosure portion configurable between a stowed state and a deployed state, in which the enclosure portion substantially shields over an end of the bed or chair; a ventilation unit configured for applying air pressure to an area beneath the enclosure portion when the enclosure portion is in the deployed state; and a portable frame to which the enclosure portion and ventilation unit are mounted.
