An ambulance cot having a wheeled base, a horizontally oriented patient litter support disposed on the base and having an elongate guide extending lengthwise thereof. A support mechanism is provided for supporting the patient litter support for vertical movement relative to the base while being maintained in the generally horizontal orientation. A device for selectively locking the patient litter support at selectively different vertical elevations is provided.

Ambulance cot

A hospital bed includes an articulatable patient support with a fowler portion movable between horizontal and inclined positions relative to a frame of the bed. A reversible electric drive motor is supported on the frame of the bed and, through a reduction gearing arrangement and a releasible coupling mechanism, can rotatably drive a threaded shaft. A nut engages and is held against rotation with the shaft, and a linkage arrangement couples the nut to the fowler portion to effect reciprocal movement of the fowler portion in response to reciprocal movement of the nut along the shaft. A manual release is provided on the fowler portion and, when actuated, disengages the releasible coupling mechanism so that the threaded shaft is free to rotate independently of the motor and gearing arrangement.

Quick release coupling for head section of a hospital bed

A hospital bed has an articulated patient support surface with four air outlet housings mounted thereon at spaced locations. An air supply arrangement supplies temperature-controlled air to an air outlet opening in each of the housings. Associated with each housing is an elongate tubular fabric diffusion member having an O-ring which encircles one end thereof and is removably received in a circumferential groove in the air outlet opening. Each diffusion member can be tucked completely into its housing when not in use. Each housing has a cap movable between open and closed positions with respect to the air outlet opening, and an arrangement yieldably urging the cap toward its closed position. A valve arrangement is provided below two of the housings in order to automatically discharge fluids which happen to enter the air supply system through the air outlet openings. In a variation, two of the elongate diffusion members can be replaced with an inflatable underlay or overlay having two inlet sleeves with O-rings which are each releasably coupled to a respective one of the air outlet devices.

Bed having patient warming apparatus

A delivery bed includes two spaced foot support assemblies which project outwardly from one end thereof. Each foot support assembly includes a first horizontally extending member having a top surface with transversely extending grooves and having a bottom surface, and a second member having two spaced, transversely extending rods which respectively slidably engage the top surface and bottom surface of the first member, the second member having therein a foot-shaped recess. A pad can be removably supported on the two foot support assemblies without any need for additional support structure for the pad intermediate the foot support assemblies. The pad is held in place by two fastening straps which extend downwardly between the foot support assemblies and are each releasably coupled to a respective one of the foot support assemblies. Alternatively, the pad can be held in place by brackets on the pad which releasably engage brackets provided on the foot support assemblies near the outer ends thereof.

Breakaway foot section for delivery bed

A hospital bed includes a base supported by casters, and a lift arrangement vertically movably supports a patient support section on the base. The lift arrangement includes a threaded first member secured to and projecting downwardly from the patient support section, a rotatably supported tubular second member having an internal thread which engages the threaded first member and having an external thread, and a further member which is supported on the base and has a thread engaging the external thread on the tubular second member. In one embodiment, the further member is a nut fixedly supported on the base, and a drive member rotatably supported on the base has an opening through which the second member extends and has a key portion which slidably engages an axially extending slot provided in the second member. In a different embodiment, the further member is itself rotatably supported on the base and has therethrough an opening through which the second member extends, the thread on the further member being an internal thread in the opening.
