Methods of translating hospital chair beds with articulating foot sections

摘要

A hospital bed includes a base, a lifting mechanism, a rotating frame configured to rotate horizontally relative to the base, and a patient support surface pivotally secured to the rotating frame. The patient support surface includes a back section, a seat section, and foot section that articulate relative to each other. The patient support surface translates from a bed configuration to a side-egress chair configuration. The foot section includes a plurality of panels that translate relative to each other from a substantially co-planar relationship when the patient support surface is in a bed configuration to a relationship where one of the foot section panels is substantially orthogonal to another foot section panel when the patient support surface is in a chair configuration. A mattress supported by the patient support surface has a retractable foot portion that adjusts its length in response to translation of the foot section panels.

主权项

1. A method of translating a hospital bed to an egress configuration, comprising:
articulating back, seat and foot sections of a patient support surface relative to each other from a substantially co-planar configuration to a chair configuration, wherein the foot section comprises first and second panels that are translatable relative to each other; and translating the first and second foot section panels so that the first and second foot section panels are substantially orthogonal to each other and such that a first portion of the second panel extends under the first panel toward an interior space of a base of the bed and a second portion of the second panel smaller than the first portion resides forward of the first panel.
