  • Publication number: 20260185723
    Abstract: A heating, air conditioning, and dehumidifier (“HACD”) system and methods of use are provided. The system may include an outdoor system and an indoor system. The outdoor system may include a compressor, a fully controlled condenser fan, a condenser coil, and a 3-way reheat valve. The indoor system may include a hot gas reheat coil, a thermal expansion valve (“TXV”), a check valve, a metering device, a blower motor, and an evaporator. The HACD system may include a refrigerant and a refrigerant piping system. The refrigerant piping system may include a first pipe being a compressor discharge pipe, a second pipe, a third pipe, and a fourth pipe being a suction line pipe. The indoor system may be configured to be confined to a form factor footprint such that physical dimensions of the indoor system are less than or equal to about 28×25.5×52 inches.

  • Patent number: 10639404
    Abstract: Apparatus and methods for providing a wound dressing are provided. A wound dressing according to the invention may preferably include a wound-fluid negative pressure treatment (“NPT”) drain and a vacuum/drainage tube comprising a terminus associated with the NPT drain. The dressing may also include a fluid-absorbing/transferring material. The dressing may also include a contour-conforming draping layer for draping over a wound-bed. The draping layer may be in contact with at least a portion of the fluid-absorbing/transferring material. The dressing may also include a vapor sealant sheet that overlies at least a portion of the fluid-absorbing/transferring layer. The material may also include a tube-anchorage component that is in contact with at least a portion of the vapor sealant sheet. The tube-anchorage component may mechanically maintain placement of the NPT drain within the fluid-absorbing/transferring material.

A wound dressing according to the invention may preferably include a wound-fluid negative pressure treatment (“NPT”) drain and a vacuum/drainage tube comprising a terminus associated with the NPT drain. The dressing may also include a fluid-absorbing/transferring material. The material may include an upper layer and a lower layer. The material may enfold the drain between the lower layer and the upper layer. The dressing may also include a contour-conforming draping layer for draping over a wound-bed. The draping layer may be in contact with at least a portion of the fluid-absorbing/transferring material. The dressing may also include a vapor sealant sheet that overlies at least a portion of the fluid-absorbing/transferring layer. The material may also include a tube-anchorage component that is in contact with at least a portion of vapor sealant sheet. The dressing may further include a tube-exit-sealant component.
