Low profile forced-air blanket
The invention includes a forced-air blanket for providing a profusion of air to a patient, comprising a bottom layer with a plurality of openings configured to allow a profusion of air to pass through the bottom layer and an upper layer bonded to the bottom layer around a periphery, wherein the upper layer is also bonded to bottom layer by a plurality of linear seals and a plurality of staked seals. In an embodiment, at least one of more of the linear seals have one end which is joined to a portion of the periphery. In another embodiment, the forced-air blanket may further include at least one elongated seal that is positioned proximate to the inlet. The arrangement of the plurality of staked seals, elongated seals and linear seals assists in providing a blanket that is of a low-profile with even air distribution.
Human thermoregulation simulator
Various implementations include a Human Thermoregulation Simulator (HTRS) that simulates the natural and primary thermoregulatory functions of a patient that are relevant during therapeutic hypothermia procedures. For example, in various implementations, a HTRS includes a core container configured to be at least partially filled with water, and the core container includes a heat generator configured to heat the water inside the core container. A middle container is disposed concentrically around the core container, and the middle container includes a foam layer configured to be saturated by water. An outer container is disposed concentrically around the middle container, and the outer container includes a network of tubing disposed on at least a portion of an inner surface of the outer container. The HTRS also includes a pump configured to circulate water from the core container through the network of tubing.
CLINICAL GARMENT WITH INSULATION
Aspects of the present disclosure can be related to a warming device, systems, and methods of using. The warming device can include a clinical garment comprising a body portion adapted to cover a portion of a patient, an inner surface configured to face the patient, and an outer surface opposite the inner surface. The body portion can include sleeves sized and positioned for receiving the patients arms. In addition, the clinical garment can include an insulative layer comprising an insulative edge portion disposed on the clinical garment. The insulative edge portion is configured to make the warming device non-linting.
Convective Warming Device
Aspects of the present disclosure relate to a warming system including a warming device. The warming device includes a clinical garment comprising a body portion adapted to cover a portion of a patient, an inner surface for facing the patient, and an outer surface for facing away from the patient. The body portion includes sleeves sized and positioned for receiving the patient's arms and a torso portion adapted to cover an anterior torso of a patient. A first pneumatic convective device can be disposed adjacent to the inner surface of the clinical garment. The pneumatic convective device can include an opening formed in the clinical garment for admitting a stream of pressurized, warmed air into the first pneumatic convective device. The warming system can also have a second pneumatic convective device in a fully-folded configuration or partially-folded configuration and disposed on a portion of the clinical garment.
Liquid Ventilation System
A liquid ventilation system includes a reservoir holding a perfluorochemical (“PFC”) fluid, and a suction pump connected to the reservoir to reduce pressure within the reservoir. A sensor is configured to measure an intra-lung pressure. An appliance is configured to be disposed within a patient. The appliance carries an injector to supply the PFC fluid through the appliance. An extraction valve is disposed on an extraction line between the appliance and the reservoir. The extraction valve is arrangeable between a first position enabling fluid communication from the appliance to the reservoir and a second position disabling fluid communication from the appliance to the reservoir.
Dermal heatsink exhibiting hydrophilic and contaminant resistant properties and method for fabricating a dermal heatsink
One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.
HYPOTHERMIC TREATMENT SACK
Hypothermic treatment sacks are provided. A hypothermic treatment sack includes a top sheet that defines a first outer perimeter. The hypothermic treatment sack further includes a bottom sheet that defines a second outer perimeter. The first outer perimeter of the top sheet is removably coupled to the second outer perimeter of the bottom sheet such that a patient receiving cavity is defined between the top sheet and the bottom sheet. The top sheet and the bottom sheet include a weather resistant external layer, a heat reflective interior layer, and an insulation layer. The insulation layer is disposed between the external layer and the heat reflective interior layer.
COLD AND HOT COMPRESS PACK AND MANUFACTURING METHOD THEREFOR, AND COLD AND HOT COMPRESS CIRCULATION SYSTEM
A cold and hot compress pack includes a first sheet (110), a second sheet (120), a third sheet (130), a first weld seam (210), a second weld seam (220), a gas port (310) and at least two liquid ports (320). The first sheet (110), the second sheet (120) and the third sheet (130) are sequentially stacked one above another. The first weld seam (210) joins the first sheet (110), the second sheet (120) and the third sheet (130) at a same planimetric position. The second weld seam (220) surrounds the first sheet (110), the second sheet (120) and the third sheet (130) and joins them together at a same planimetric position. The second weld seam (220) is joined to one end of the first weld seam (210), thereby forming a first cavity (141) between the first sheet (110) and the second sheet (120) and a second cavity (142) between the second sheet (120) and the third sheet (130). The gas port (310) is arranged between any two of the liquid ports (320) so as to be spaced apart from both. The at least two liquid ports (320) are in communication with the second cavity (142), and the gas port (310) is in communication with the first cavity (141). An end of the first weld seam (210) joined to the second weld seam (220) extends between the gas port (310) and any one of the liquid ports (320) while being spaced apart from both. Also disclosed are a corresponding manufacturing method and a cold and hot compress circulation system.
CONFIGURABLE CONVECTIVE DEVICE
At least some aspects of the present disclosure feature a configurable convective device, including two layers forming a pneumatic structure and an air-guide device. The pneumatic structure includes two portions and an inflatable channel connecting the two portions. In some cases, the air-guide device is disposed within or proximate to the inflatable channel and configured to direct flow of inflation medium when at least one of the two portions are bent.
CRYOGENIC GARMENT
A cryotherapy garment includes a number of receptacles that receive at least one pack of cold-store material. Each of the receptacles is formed by a closed fabric fold in the garment. Each of the receptacles has an opening for insertion of the pack of cold-store material. Each receptacle receives a respective pack, which is made of a semi-rigid material.
