THERMAL SYSTEM WITH THERMAL PAD FILTERS
20200179161 · 2020-06-11 ·

A thermal pad is adapted to be placed in physical contact with a patient and to receive temperature controlled fluid from a thermal control unit. The temperature controlled fluid circulates through the thermal pad and controls the patient's temperature. The thermal pad includes first and second sheets that are sealed together about their periphery to define a fluid chamber there between. A fluid inlet and fluid outlet are fluidly coupled to the fluid chamber. In some embodiments, a filter sheet is sandwiched between the first and second sheets and arranged such that fluid entering the fluid inlet must pass through the filter sheet before exiting out of the fluid outlet. A plurality of bonds may be included that seal the first and second sheets together at a plurality of locations. In some embodiments, a non-sheet filter is positioned within the fluid chamber and filters the circulating fluid.

TOURNIQUET AND TISSUE PRESERVATION SYSTEM
20200146692 · 2020-05-14 ·

A tourniquet apparatus (10) comprises at least two expandable members (21,22) configured for applying pressure on a limb of a subject; and actuating means (143,144) for actuating the at least two expandable members (21,22), wherein the actuating means (143,144) are configured to actuate each expandable member independently and/or selectively. There is also provided a limb-cooling apparatus (200) comprising an inner stretchable layer (210) configured to engage and/or contact a limb of a subject; an outer layer (220) at least partially attached to the inner layer (210); and a cooling system (240) configured to supply a cooling medium (250) between the inner layer (210) and the outer layer (220).

CERVICAL COLLAR

10478637 · 2019-11-19 · ·

A cold cap adapted for connecting to a chiller unit for circulating chilled fluid through the cap. The cap is formed from at least three layers of material which are sealingly attached around their periphery so as to form a cooling fluid chamber, wherein the cap is configured to apply compression and cooling to the scalp.

Thermal device

A thermal device comprising a garment (42A) that may be placed against at least a part of the body (10), the garment (42A) defining at least one enclosed compartment (48, 50) defined between an inner wall (65) and an outer wall (66), and an inlet (21) whereby liquid may be introduced into each such enclosed compartment (48, 50). Each enclosed compartment (48, 50) contains dry material (30) comprising water-soluble chemical compounds that dissolve endothermically or exothermically, and also a compressed sponge (62). There may also be an air bleed valve (64) to bleed any air out of the compartment (48, 50) when water is introduced. The device enables a patient's body to be cooled or heated in emergency, needing only addition of water, and incorporating no toxic or hazardous materials.

Patient warming device with patient access

A patient warming device with patient access for maintaining normothermia and/or treating hypothermia is provided. The device includes a first compliant layer and a second compliant layer sealed together around an outer border to contain a liquid between the two layers and to form a wrap that surrounds and conforms to a body portion of a patient. A plurality of flaps extends from opposite sides of a generally longitudinal central portion of the wrap, such that one or more flaps from the opposite sides fasten to each other to surround the body portion. The flaps are openable during functional use to provide access to an underlying patient body surface. A continuous fluid flow path extends between the first compliant layer and the second compliant layer between a fluid inlet and a fluid outlet to carry liquid and deliver heat through the wrap.

A Thermal Pack that Conforms to Curved Surfaces
20190216640 · 2019-07-18 ·

A thermal pack comprises a first and second plastic sheets that form a sack. The sack contains a flowable thermal material and further includes a plurality of joint lines within the sack that are in contact with the thermal material.
