  • 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. The cover is movable by a caregiver between three positions: (i) a stowed position secured within the keeper, (ii) an environmental deployed position with the first side facing towards the mattress, and (iii) a patient deployed position with the first side facing away from the mattress.

  • Patent number: 11986429
    Abstract: A patient transport apparatus is provided with a lift mechanism to move a litter relative to a base between lift configurations, a user interface with an input control and an indicator, a height sensor, and a controller. The controller is configured to compare signals generated by the height sensor against a value associated with a transport configuration, operate the indicator in a first state when the signal corresponds to the value to communicate to a user that the litter is arranged in the transport configuration, to operate the indicator in a second state when the signal differs from the value to communicate to the user that the litter is arranged in a lift configuration other than the transport configuration, and to drive the lift mechanism to move to the transport configuration in response to the signal being within a predetermined threshold of value upon user disengagement of the input control.

  • Patent number: 11801161
    Abstract: A reinforcing clinical wrap is provided with integral thermal management. The clinical wrap includes a fluid circuit for a heat transfer medium to circulate between a fluid inlet and a fluid outlet. A shape conforming medium is disposed within a portion of the clinical wrap providing selective reinforcement support of the portion of the clinical wrap to conform to a surface of a patient. Non-limiting examples of the shape conforming medium may include a magnetorheological elastomer, a magnetorheological elastomer, a magnetorheological foam, a UV curable resin, and a phase change material.

  • Patent number: 11779497
    Abstract: A patient transport apparatus transports a patient over a floor surface and includes a support structure and a plurality of support wheels coupled to the support structure. The patient transport apparatus also includes a user interface including at least two handles coupled to the support structure, with each of the handles movable between a stowed position and non-stowed position. The patient transport apparatus also includes a user input device coupled to the user interface, and a controller coupled to the user interface. The controller is configured to electronically coordinate the movement of the handles to the stowed position upon actuation of the user input device.
