  • Patent number: 11844730
    Abstract: A patient support apparatus supports a patient for movement assisted by first and second caregivers and includes a litter. The litter includes a patient support deck extending between first and second ends and defines at least one cavity. First and second evacuation interfaces are coupled to the litter. The first and second evacuation interfaces pivot between first and second unfolded positions and first and second upright positions, respectively, and move between first and second lengthened positions and first and second shortened positions, respectively. The first and second evacuation interfaces are disposed in the cavity when the first and second evacuation interfaces are in the first and second unfolded positions and the first and second shortened positions, respectively, and configured to be grasped and lifted by the first and second caregivers when the first and second evacuation interfaces are in the first and second upright positions, respectively.

  • Patent number: 11826284
    Abstract: A patient support apparatus supports a patient and comprises a litter. The litter comprises a patient support deck and extends longitudinally between first and second ends. A base is configured to support the litter and comprises a base lift mechanism configured to move the litter between lifted and lowered base positions. A side ramp is coupled to the patient support deck along the litter between the first and second ends and extends laterally away from the patient support deck to an engagement end. The side ramp is pivotable relative to the litter between first and second positions. In the first position, the side ramp is planar with or angled upwardly to extend above the patient support deck. In the second position, the side ramp is angled downwardly to extend below the patient support deck for contacting the floor surface with the engagement end when in the lowered base position.

  • Patent number: 11723817
    Abstract: A patient support apparatus supports a patient and includes a litter. The litter includes a patient support deck and extends longitudinally between first and second ends. The apparatus includes a litter lift device coupled to the litter and configured to raise and lower the patient support deck. The apparatus includes a care station coupled to the litter adjacent one of the first and second ends. The care station includes a docking frame coupled to the litter and defining an angle between the docking frame and the axis. The docking frame is arranged to pivot relative to the litter between a folded position an upright position. The angle in the folded position less than the angle in the upright position. The care station includes a utility module configured for use by a caregiver and arranged to selectively mount to the docking frame.

  • Patent number: 11723818
    Abstract: A patient transport apparatus including a patient litter and a litter support apparatus for supporting the patient litter from a ground surface. The litter support apparatus includes a litter support frame including a pair of litter supports spaced a distance apart to define a loading gap for receiving the patient litter therethrough. A handle system is coupled to the pair of litter supports and includes a handle assembly that is positionable between a closed configuration and an open configuration. The handle assembly extends across the loading gap defined between the pair of litter supports in the closed configuration and is positioned away from the loading gap in the open configuration.

  • Publication number: 20210309881
    Abstract: Powder coating compositions that include an epoxy resin composition and a curing agent are described. The powder coating compositions can be applied at low application temperatures of about 165° C. to 185° C. The coating compositions can be used to form fusion-bonded single layer and dual-layer epoxy pipe coatings, and demonstrate optimal corrosion resistance and flexibility with reduced cathodic disbondment.
