A bed covering having a plurality of layers between which is an air cavity and having at least one air inlet in fluid communication with the air cavity. The layers have folds and have fasteners. The fasteners may fasten and unfasten and include respective fastener components that self-close when brought together to engage each other and that disengage to separate from each other. The fastener components when fastened to each other close the at least one air inlet and when unfastened from each other open the at least on air inlet. An elastic band is also provided on the periphery to wrap around an air tube when inserted into the at least one air inlet and apply an elastic force under tension to retain the same.

A thermal therapy device can be operated for both cold and hot water circulation by using a self-priming pump and four solenoid valves with the open/closed states selectively controlled by an MCU to pump chilled water or cold water from two different water containers to sequentially circulate through two different water paths to a water bladder for cold therapy treatment or hot therapy treatment. During the hot therapy treatment, a water heater is used to heat the cold water until a configured temperature is reached. A pneumatic pump is also employed to carry out an air pressure control mode to pump air into an air bladder securely attached on the water bladder to put pressure on the water bladder for a pressurized treatment. Water retained in the water bladder can also be evacuated and returned to the two different water containers to avoid moss generation and stinky odor.

The module including a lower section configured to house unrelated waste heat-producing electronic and electromechanical surgical equipment during surgery and a tower-like upper section located above the lower section. A rear portion of the lower section is configured to fit into an unused space under an arm-board of a surgical table. The upper section is configured to be positioned adjacent an anesthesia side of an arm-board of the surgical table and the upper section is configured to accommodate mounting of equipment controls and a display at a height to be viewed and operated by a user.

Described herein is a warming blanket having a structure comprising a first layer of material forming a bottom layer with openings to allow a profusion of air through the bottom layer, a second layer of material forming an upper layer wherein the upper layer is coupled to the bottom layer to form an initial shape of the warming blanket and to form a plurality of interconnected air passageways between the first and second layers of material, wherein at least a portion of the structure is deformable in at least one dimension to reshape the periphery of the warming blanket while maintaining the integrity of the interconnecting air passageways throughout the structure; and wherein the deformable portion of the blanket is deformable by at least a 50% elongation. Examples of materials comprising the deformable portions of the warming blanket include low density polyethylene, metallocene polyethylene, polypropylene, parafilm, and polyurethane.

A cold and heat exchange system for a cardiac surgical operation with cardiac arrest, comprising: an ice water tank (15), a primary circulation water tank (11), and a secondary circulation water tank (16). Side walls of the primary circulation water tank (11) and the secondary circulation water tank (16) are each provided with an overflow orifice which is connected to the ice water tank (15) through a circulation pipe (14). A first roller pump (12) is mounted on a first hose (13). A second roller pump (18) is mounted on a second hose (17). The primary circulation water tank (11) is mounted on a first loop (5) and a second loop (6). The secondary circulation water tank (16) is mounted on a third loop (1).

A module for housing electronic and electromechanical equipment and for managing waste heat during surgery. The module including a lower section including a bulbous portion and a tower-like upper section located on top of the lower section. The bulbous portion can be configured to be positioned under an arm overhang of a surgical table. A water-resistant cowling can enclose at least a portion of the lower section and the tower-like upper section. An air inlet vent can be provided in the cowling of the lower section to allow air to enter and cool the electronic and electromechanical equipment housed in the lower section. The tower-like upper section can serve as a chimney allowing a convection current of waste heat to rise within the tower-like upper section and be discharged from outlet vents located near the top of the tower-like upper section.

A thermal control unit for controlling a patient's temperature includes a fluid outlet for delivering temperature-controlled fluid to a patient, a pump, a heat exchanger, and a controller that automatically implements a step change in the temperature of the fluid delivered to the patient. The step change is implemented prior to the patient reaching a target patient temperature. In the moments after (and in some cases the moments before) the step change, the controller monitors the rate of change of patient's temperature to evaluate whether the patient will reach the target patient temperature without reversing the step change, and/or how long it will likely take for the patient to reach the target patient temperature without reversing the step change. The controller then determines whether to reverse the step change or to switch to another algorithm for controlling the fluid temperature.

At least some aspects of the present disclosure feature a tubular convective device, comprising: a blown film forming a tube when inflated, the blown film having a first portion and a second portion, wherein the first portion and the second portion are separated longitudinally, and a plurality of apertures disposed on the first portion of the blown film. At least some aspects of the present disclosure feature a tubular convective system including a plurality of tubular convective devices, where adjacent tubular convective devices are connected.

A device for warming a human body. The device is a gown (100, 1500) that has a thorax portion (110, 1502) and a leg portion (112, 1504). One embodiment prevents redistribution hypothermia with a distributor (206) attached to the inside of the leg portion (112). The sleeves (108), leg portion (112), and posterior of the gown (100) are heat reflective. The anterior of the thorax portion (110) of the gown is non-reflective. The distributor (206) inflates when heated air is supplied and exhausts air into the gown (100). Temperature is maintained at a desired level for the extremities, while preventing the thorax area from being elevated to an uncomfortable level. Another embodiment is a perioperative warming device. The device is a gown (1500) that has a thorax portion (1502) and a leg portion (1504). Each portion has an independent air chamber and inlet. The two portions are releasably connected. The sleeves (1508), leg portion (1504), and anterior of the gown (1500) are heat reflective.

A method of manipulating a quick connect/disconnect system includes connecting a first coupling portion of a first connecting member to a fluid conductor and inserting a second coupling portion of the first connecting member within a third coupling portion of a second connecting member. The method further includes inserting the third coupling portion within a ring assembly which is rotatably coupled to the first coupling portion and engaging a mating feature on an external surface of the third coupling portion with a mating feature on an internal surface of the ring assembly. The method also includes rotating the ring assembly about the third coupling portion while the first mating portion is engaged with the second mating portion; and forcing the second coupling portion to move further within the third coupling portion by rotation of the ring assembly.
