Abstract

A hospital bed has a frame mounted on a base. Articulating head, seat and leg patient support panels are mounted on the frame. Side guards are mounted on the panels. Patient support panels have longitudinal edges that are collapsible to narrow the bed for transporting a patient. The side guards are inwardly movable to contribute to the narrowing of the bed while still protecting the patient from falling out of the bed.

Claims

1. A hospital bed comprising:

a base,

a bed frame mounted on said base,

a plurality of patient support panels mounted on said base in a longitudinally-spaced series,

a mattress overlying said panels;

said mattress having a plurality of main mattress sections, each having an upper surface, and having a plurality of side sections substantially hollow on each side of said main mattress sections, each of which side sections is selectively individually inflatable to widen at least a portion of said bed, said side sections when inflated having upper surfaces substantially co-planar with said upper surfaces of said main mattress sections to provide a patient support surface of extended width, each of which side sections is selectively individually deflatable and inwardly collapsible to narrow at least a portion of said bed to provide a patient support surface of narrowed width.

2. A hospital bed as in claim 1 wherein said patient support panels include a head panel,

a pair of deflatable side sections coextensive with said head panel,

and a side guard on each side of said bed having a portion disposed adjacent said head panel,

means for moving said side guard laterally inwardly to overlie the patient support panels,

said side sections coextensive with said head panel being deflatable to permit said head panel to pivot upwardly past said side guards, thereby permitting a patient to sit up while said side guards are effective to confine the patient to its bed.

3. A hospital bed as in claim 1 in which:

deflatable side sections are disposed along the whole length of each side of said bed,

a side guard mounted on each side of said frame and normally projecting above the level of said mattress to confine a patient to its bed,

means for mounting said side guard on said frame to permit it to be lowered below the level of said mattress and thrust laterally inwardly,

whereby upon deflating said side sections along one side and thrusting said side guard down and in, said bed can be narrowed to facilitate transfer of a patient to another surface.

4. A hospital bed as in claim 1, further comprising:

a side guard mounted on said frame for lateral movement in and out with respect to said frame,

said side guard being mounted on a pair of longitudinally spaced vertical posts,

said side sections having a pair of gaps between sections aligned with said posts to permit said side guard to be moved inwardly without interference from side sections, thereby narrowing said bed for patient transport with side guards in elevated position to protect the patient.
