Air purification tent
11690460 · 2023-07-04 · ·

An air purifying bed tent is disclosed, having a tent made from a semipermeable material suspended over a raised platform, thereby creating an enclosure for a user to be inside. An air purifying device is connected to the top of the tent, letting purified air into the enclosure and creating a local clean air zone for users. The positive pressure difference building up in the enclosure from the constantly added clean air forces clean air out through a plurality of openings, primarily through creases in the semipermeable material around the raised platform. Should the skirting be completely sealed, the semipermeable material will let out the pure air to a higher degree, ensuring a stable and easy touse operation.

Patient support surface control, end of life indication, and x-ray cassette sleeve

A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

Increasing the heat flow of flexible cellular foam through the incorporation of highly thermally-conductive solids

Methods and combinations of mattress support surfaces comprising one or more flexible polyurethane foam layers containing highly thermally-conductive solids, such as diamond or silicon carbide, and said layer combination is capable of transferring heat from a warm surface, such as a person sleeping on a bed, to a cooler region at a faster rate throughout the mattress than the thermal dissipation rate obtained from flexible polyurethane foam without highly thermally-conductive solids.

Electric heating pads and mattresses

An electric heating pad for warming a patient includes a heated underbody support or heated mattress. The heated underbody support or mattress includes a heater assembly having a flexible sheet-like heating element, conductive bus bars attached at or near side edges of the heating element, and fabric side edge extensions attached to heating element side edges. The heated underbody support or mattress also includes a layer of polymeric foam positioned under the heater assembly and a shell, including at least two sheets of flexible material, covering at least a portion of the heater assembly and the layer of polymeric foam. When the heater assembly is wrapped around the top surface of the layer of polymeric foam, side edges of the heating element extend partially down the two side walls of the layer of polymeric foam and the conductive bus bars lie adjacent those two side walls.

BODY SUPPORT ASSEMBLY
20220395104 · 2022-12-15 · ·

Body support assembly (1) having a top surface (2) and a spaced away bottom surface (3) defining a cushion volume (4) and defining side walls (5). The air permeability of the top surface (2) is higher than the air permeability of the bottom surface (3). The cushion volume (4) comprises an upper cushion zone (7) and a lower cushion zone (8) and separated by a separation sheet (9). The upper cushion zone (7) and the lower cushion zone (8) comprise of a compressible material (10) which is permeable for air in all directions. The cushion volume (4) further comprises a flow path for air comprising an air inlet (6) in the bottom surface (3), air displacement means (20), a heat exchanger (21), a flow path through the compressible material of the lower cushion zone (8), through openings in the separation sheet (9) and through the compressible material (10) of the upper cushion zone (7) and multiple air outlets as present in the top surface (2).

REVERSIBLE MATTRESS TOPPER
20220369825 · 2022-11-24 ·

A reversible mattress topper for a mattress is provided that includes opposing first and second panels. A fill material is intermediate the first and second panels. The panel materials and/or selected portions of the filler material will be selected to provide either cooling or comfort for the sleeper. One surface of the reversible mattress topper will be configured to be cooling in nature. The other surface of the reversible mattress will be comforting and optionally warming in nature. The panels can be stylized in order to communicate which surface provides cooling and which surface provides warming.

Sleep phase dependent temperature control and learning methods to optimize sleep quality
11503918 · 2022-11-22 · ·

A bed includes components to control temperature of a sleep surface, for example based on time and historical usage patterns by a user. In some embodiments the temperature of the sleep surface is controlled based on information indicating a sleep state of the user. In some embodiments the temperature is dynamically adjusted so to achieve particular sleep states and/or sleep patterns for the user. In some embodiments the temperature and timing of temperature adjustments is iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.
