  • Patent number: 12667508
    Abstract: A shield assembly for providing a barrier adjacent to a patient disposed on a patient support apparatus. The shield assembly comprises a support frame defining a closed periphery and including a resilient element extending along the closed periphery to resiliently urge the support frame toward a bias frame shape. A barrier panel is coupled to the support frame and spans the closed periphery. The shield assembly may further include a base operatively attached to the support frame to selectively place the support frame in a contour frame shape. Tension in the resilient element effected by the base holding the support frame in the contour frame shape places the barrier panel in a curved configuration to define a patient accommodation space shaped to receive the patient adjacent to the base and to the barrier panel.

  • Publication number: 20260083609
    Abstract: A patient transport apparatus comprises a support structure and at least one caster assembly coupled to the structure to facilitate movement of the structure along a floor. Each caster assembly comprises a wheel, an actuator moveable between three actuator positions, a steer lock assembly moveable by the actuator between a steer and non-steer locked state, and a brake assembly movable by the actuator between a braked and unbraked state. The brake assembly includes a plunger, a retainer coupled to the plunger, a brake pad for sliding movement along the retainer, and a brake biasing element disposed between the plunger and the brake pad to urge the brake pad away from the plunger such that movement of the actuator to place the brake assembly in the braked state simultaneously brings the brake pad into engagement with the wheel and slides the brake pad along the retainer to compress the biasing element.

  • Patent number: 12533270
    Abstract: A patient transport apparatus comprises a support structure comprising base, a frame, and a patient support surface to support a patient. The apparatus also includes at least one caster assembly coupled to the support structure, with each one of the caster assemblies comprising a wheel, a wheel support coupled to the wheel, and a steer lock assembly movable relative to the wheel support. An actuator is operatively coupled to the steer lock assembly to move the steer lock assembly between a non-steer locked and steer locked state to permit or prevent the wheel support and coupled wheel from swiveling about a swivel axis. The caster assemblies can also include a brake assembly coupled to the wheel, with the actuator operatively coupled to the brake assembly to move the brake assembly between a braked and unbraked state.

  • Patent number: 12496243
    Abstract: A patient transport apparatus comprises a support structure and at least one caster assembly coupled to the structure to facilitate movement of the structure along a floor. Each caster assembly comprises a wheel, an actuator moveable between three actuator positions, a steer lock assembly moveable by the actuator between a steer and non-steer locked state, and a brake assembly movable by the actuator between a braked and unbraked state. The brake assembly includes a plunger, a retainer coupled to the plunger, a brake pad for sliding movement along the retainer, and a brake biasing element disposed between the plunger and the brake pad to urge the brake pad away from the plunger such that movement of the actuator to place the brake assembly in the braked state simultaneously brings the brake pad into engagement with the wheel and slides the brake pad along the retainer to compress the biasing element.

  • Publication number: 20250325428
    Abstract: A patient support apparatus supports a patient and includes a litter. A base is disposed below the litter. A lift mechanism is configured to move the litter and the base relative to one another between extended and collapsed positions. The lift mechanism includes first and second frame assemblies each including an outer frame member and an inner frame member arranged to move within the outer frame member. First and second rollers and first and second slide members are disposed between the outer and inner frame members. The first and second rollers are arranged to roll along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the litter. The first and second slide members are arranged to slide along at least one of the outer and inner frame members with a load exerted on the lift mechanism from the base.

  • Publication number: 20250228718
    Abstract: A patient transport apparatus including a base, a litter, a lift mechanism, a litter extension and a cable assembly. The lift mechanism is interposed between the base and the litter and includes an actuator for moving the litter relative to the base. The litter extension moves relative to a patient support surface of the litter between a plurality of litter extension positions. The cable assembly includes a cable and a cable housing. The cable translates mechanical force applied to a user interface of the letter extension to the actuator. The cable housing is operatively attached to the litter and defines an inner cavity, a guide disposed within the inner cavity. The cable housing retains at least a portion of the cable as the litter extension moves between the plurality of litter extension positions.

  • Patent number: 12263126
    Abstract: A protective system for a patient transport apparatus includes the patient transport apparatus with a base arranged for movement along floor surfaces and an intermediate frame coupled to the base and supporting a patient support deck. A mattress is disposed on the patient support deck. The protective system further includes a keeper coupled to the intermediate frame and further includes a cover having a first side configured to absorb fluid and a second side configured to at least partially limit fluid from transferring through the cover towards the first side.
