Abstract
Abstract A hospital bed has, at least at its head end, longitudinally extending inflatable mattress sections on each side of the bed. When those mattress sections are deflated, that portion of the bed can be narrowed to permit a nurse to move into the vacated space along side the bed and to permit hospital equipment such as an IV rack to be moved into the vacated spaced on the other side of the bed. Thus, the nurse can conveniently reach the patient as well as the patient care instruments on the opposite side of the bed.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
95 words
A hospital bed comprising, a base, patient support panels mounted on said base, said panels including a head panel for supporting the upper part of a patient's body, said head panel having longitudinal wings a mattress, covering said panels, said mattress being formed in part by inflatable side sections overlying said wings, which, when deflated, narrow a patient's support area thereby permitting a nurse to stand closer to a patient on one side of said bed and to bring patient care equipment closer to the patient and nurse on the other side of said bed.
Claim 2
Dependent Claim
95 words
A hospital bed comprising, a base, patient support panels mounted on said base, said panels including a head panel for supporting the upper part of a patient's body, said head panel having longitudinal wings a mattress, covering said panels, said mattress being formed in part by inflatable side sections overlying said wings, which, when deflated, narrow a patient's support area thereby permitting a nurse to stand closer to a patient on one side of said bed and to bring patient care equipment closer to the patient and nurse on the other side of said bed.
Claim 3
Dependent Claim
29 words
A hospital bed as in claim 1 in which said wings having means for collapsing said side sections when said side sections deflate as said wings are swung upwardly.
Claim 4
Dependent Claim
58 words
A bed as in claim 2, said wings each having a manifold extending along its length, said manifold having a plurality of port connected to the interior of a bladder, a source of compressed air, means for connecting said compressed air source to said manifold when the wing is in a horizontal position thereby to inflate said bladder.
Claim 5
Dependent Claim
19 words
A bed as in claim 3 further comprising power means for swinging said wings between horizontal and vertical positions.
Claim 6
Dependent Claim
100 words
A hospital bed as in claim 1 in which said mattress side sections comprise, said elongated wings hinged to said panel to swing between horizontal and vertical positions, said wings having a plurality of ports along their length, means for closing said ports when said wings are in a horizontal position and for opening said ports when said wings moves toward a vertical position to deflate said bladder, a bladder attached to each wing and having an interior connected to said ports, a source of compressed air, means for directing compressed air to said bladder when said ports are closed.
Claim 7
Dependent Claim
26 words
A hospital bed as in claim 5 further comprising, a vacuum pump, means for connecting said vacuum pump to said bladder when said port are open.
Claim 8
Dependent Claim
19 words
A bed as in claim 5 further comprising power means for swinging said wings between horizontal and vertical positions.
Claim 9
Dependent Claim
49 words
A bed as in claim 1, said inflatable side sections being formed by an open cell foam enclosed by an airtight skin, valves means for opening said skin to atmospheric pressure to inflate and deflate said foam interior, and to selectively close said skin when said cells are inflated.
Claim 10
Dependent Claim
60 words
A hospital bed as in claim 1, said head panel having an end, said inflatable side sections having ends, said section ends terminating short of said panel end to create unobstructed notches at head end corners of said bed thereby permitting patient care apparatus to swing in an arc that keeps the apparatus as close as possible to the patient.
Claim 11
Dependent Claim
61 words
A hospital bed as in claim 9 in a hospital room having a floor further comprising, a power column, an arm pivotally mounted on said floor on a vertical axis passing through said head panel, said power column being mounted on said arm for movement in an arc passing around the head end of said bed and through said unobstructed notches.
Claim 12
Dependent Claim
83 words
A hospital bed as in claim 1 further comprising, a power column disposed at one corner at the head end of said bed, an IV rack, means for disposing said IV rack in a position overlying the area, at the other head end corner, vacated by the deflated mattress side section, whereby a nurse, standing in the area vacated by said deflated side section adjacent said power column, can reach across a patient in said bed and manipulate equipment on said IV rack.
Claim 13
Dependent Claim
56 words
A hospital bed as in claim 5 further comprising, means for swinging said power column to positions at either corner of said bed, and means for positioning said IV rack at the opposite corner of said bed, whereby a nurse can administer to a patient with equal facility while standing on either side of said bed.
Claim 14
Dependent Claim
62 words
A combination as in claim 1 further comprising, longitudinal mattress sections at both sides of the head end of the bed, said sections being collapsible to narrow the bed by at least about 6 inches on a side, whereby a nurse standing on one side of a bed can easily reach a power column swung to the other side of said bed.
Claim 15
Dependent Claim
107 words
In a hospital room having a floor and ceiling, a generally rectangular bed, a power column having upper and lower ends, arms pivotally mounted at their first ends to the floor and ceiling, respectively, on an axis passing through the head end of said bed and connected at their second ends to said lower and upper ends of respectively of said power column, to permit said power column to pivot through an arc of about 180°, the corners of said bed at said head end being removed at permit said power column to swing on as small a radius as possible free from obstruction with bed corners.
Claim 16
Dependent Claim
107 words
In a hospital room having a floor and ceiling, a generally rectangular bed, a power column having upper and lower ends, arms pivotally mounted at their first ends to the floor and ceiling, respectively, on an axis passing through the head end of said bed and connected at their second ends to said lower and upper ends of respectively of said power column, to permit said power column to pivot through an arc of about 180°, the corners of said bed at said head end being removed at permit said power column to swing on as small a radius as possible free from obstruction with bed corners.
