Abstract
Abstract An emergency CPR feature is comprised of a timer and logic circuit mounted to a PC card with connections that are compatible to many existing control circuits for an adjustable hospital bed. The emergency CPR feature provides for "hands free" automatically repositioning of an adjustable hospital bed at a desired height, e.g., the full up position, with a flat mattress upon entry of a coded command by simultaneously depressing two switches, e.g., a foot and hand switch, by a trained attendant. The circuitry is contained on a single PC card which may be readily retrofit into existing adjustable hospital beds as well as incorporated into newly manufactured beds.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
In an adjustable bed having means for repositioning a plurality of portions of said bed with respect to each other, the improvement comprising a control having means for permitting an operator to input a coded command to initiate the automatic repositioning of said plurality of portions so as to bring said bed into a pre-determined position on an emergency basis, said control means having a logic means responsive to the coded operator command in order to prevent inadvertent operation.
Claim 2
Dependent Claim
79 words
In an adjustable bed having means for repositioning a plurality of portions of said bed with respect to each other, the improvement comprising a control having means for permitting an operator to input a coded command to initiate the automatic repositioning of said plurality of portions so as to bring said bed into a pre-determined position on an emergency basis, said control means having a logic means responsive to the coded operator command in order to prevent inadvertent operation.
Claim 3
Dependent Claim
24 words
The control of claim 1 wherein said control means further comprises means for permitting hands free operation after entry of said coded operator command.
Claim 4
Dependent Claim
21 words
The control of claim 2 wherein said hands free means includes a timer, said timer comprising part of the logic means.
Claim 5
Dependent Claim
35 words
The control of claim 3 wherein said control includes a plurality of momentary contact switches connected to the logic means, said coded operator command comprising operation of said momentary contact switches in a pre-determined sequence.
Claim 6
Dependent Claim
22 words
The control of claim 4 wherein said logic means is responsive to substantially simultaneous operation of two of said momentary contact switches.
Claim 7
Dependent Claim
28 words
The control of claim 5 wherein one of said two switches is adapted for foot actuation and the other of said two switches is adapted for hand operation.
Claim 8
Dependent Claim
21 words
The control of claim 3 further comprising means to reset the timer and thereby interrupt the automatic re-positioning of said bed.
Claim 9
Dependent Claim
38 words
The control of claim 1 wherein said bed has a knee adjustable portion, a back adjustable portion, and an adjustable height, said pre-determined position comprising knee down and back down thereby forming a flat bed, and height up.
Claim 10
Dependent Claim
50 words
The control of claim 8 wherein the logic means includes a timer, said timer having means for activating said knee, back, and height adjustments, and said timer being set for an interval sufficiently long to re-position said bed at the limits of travel of said knee, back, and height adjustments.
Claim 11
Dependent Claim
93 words
An electronic circuit for retrofit into the control circuit of an existing adjustable bed, said adjustable bed having means for re-positioning a plurality of portions of said bed with respect to each other, said electronic circuit comprising a PC board, and a logic means mounted on said PC board for de-coding operator entry of a coded command to initiate the automatic re-positioning of said plurality of portions so as to bring said bed into a pre-determined position on an emergency basis, said PC board being adapted for connection to said existing control circuit.
Claim 12
Dependent Claim
93 words
An electronic circuit for retrofit into the control circuit of an existing adjustable bed, said adjustable bed having means for re-positioning a plurality of portions of said bed with respect to each other, said electronic circuit comprising a PC board, and a logic means mounted on said PC board for de-coding operator entry of a coded command to initiate the automatic re-positioning of said plurality of portions so as to bring said bed into a pre-determined position on an emergency basis, said PC board being adapted for connection to said existing control circuit.
Claim 13
Dependent Claim
23 words
The electronic circuit of claim 10 wherein said logic means includes a timer for re-positioning various bed portions for a pre-determined time period.
Claim 14
Dependent Claim
22 words
The electronic circuit of claim 11 further comprising means to reset the timer and thereby interrupt the automatic re-positioning of said bed.
Claim 15
Dependent Claim
55 words
The electronic circuit of claim 12 wherein the adjustable bed has means for limiting the travel of said various bed portions, said timer being set for a sufficiently long time period to assure the complete re-positioning of the desired bed portions into the desired orientation without operator intervention beyond initial entry of said coded command.
