maneuver for a hospital patient and the like is described wherein a
first inflatable body lifts the patient partially on his side and
then a second inflatable body, during its inflation, bears on one
side against the already inflated first body and with its opposite
side exerts pushing contact against the patient to complete a body
turning maneuver or support the patient in an intermediate inclined
position. A pneumatic air control system is provided for
selectively inflating and deflating the inflatable bodies to a
desired level of pressure. In another embodiment, independently
inflatable first and second bodies are provided adjacent each side
of the patient to thereby permit turning of the patient side to
side.

Description
BACKGROUND OF THE INVENTION
The present invention generally relates to a useful medical or
patient-care aid, and more particularly to an inflatable device
effective in causing a body-turning maneuver for a hospital patient
or for selectively supporting the patient at an intermediate
inclined position.
While reclining and adjustable beds are known for elevating or
lowering the head or legs of a patient or to generally adjust his
inclination along his length, turning a patient from side to side
or selectively supporting him in an intermediate inclined position
is still an incovenient and sometimes difficult procedure.
Accordingly, there is a need for a device that can be used by a
nurse or hospital orderly to assist in turning a bed-ridden patient
or supporting him in a desired inclination, particularly in
circumstances where the patient's size makes handling difficult, or
his health condition is such that he cannot be expected to
significantly assist in this maneuver. A body-turning device for a
hospital patient of the general type under consideration is
described in my U.S. Pat. No. 3,526,908.
It is also frequently desirable to turn the patient or to support a
patient in an intermediate inclined position facing one direction
or the other. Again, there is not presently known a simple an
economical device for accomplishing such a function.
The present invention is a useful aid for hospitals and the like
and contemplates embodiments which are partially positioned beneath
a patient to thereby eliminate the requirement of fully lifting a
patient, where this is impractical. However, the present invention,
in accordance with further embodiments thereof, may also be fully
disposed beneath the patient or may be maintained beneath the
patient during his confinement. Alternately, the present invention
may be incorporated within a bed or rest surface upon which a
patient is disposed. With the latter embodiments, additional
flexibility results in the manner in which the patient may be
supported or turned.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a
patient-orienting device which is not possessed for the
disadvantages associated with prior art comparable devices.
It is another object of the present invention to provide a
patient-orienting device which is simple in construction and
economical to manufacture.
It is still another object of the present invention to provide a
body-turning device for achieving the foregoing and other
commerical requirements. More specifically, it is an object to
provide an inflatable device which, without any significant effort
to difficulty, can be positioned under one side of the patient and
then, during subsequent inflation exert firm but gentle, pushing
contact against the patient to move the patient through a
body-turning maneuver.
It is yet another object of the present invention to provide a
body-orienting device which is pneumatically controlled or
selectively supporting the patient in any intermediate inclined
position.
It is a further object of the present invention to provide a
patient-orienting device which includes independently inflatable
bodies disposed to each side of a patient to permit turning the
patient or supporting the patient in an intermediate position
facing one direction or the other.
To achieve the above objects, as well as others which will become
apparent hereafter, a patient-orienting device suitable for
hospital use and the like in accordance with the present invention
comprises a resilient body having an operative position partially
disposed beneath the patient within exposed edge therealong
adjacent one side of the patient. A first inflatable body is
provided which is connected along said exposed edge for at least
partially lifting said resilient body and the patient positioned
thereon in response to inflation of said first inflatable body. A
second inflatable body in provided which is operatively arranged
adjacent said exposed edge and adapted to be inflated subsequent to
the inflation of said first inflatable body. At least a portion of
said second inflatable body is at least partially supported by said
first inflatable body and an opposite other portion thereof is in
pushing contact against the patient. Said inflatable bodies are in
pushing contact with each other and together arranged to bear
against and push the patient relative to said resilient body when
said inflatable bodies are inflated. Pneumatic air supply means is
provided for selectively inflating and deflating said inflatable
bodies to a desired level of pressure to fully turn the patient to
support the latter in an intermediate inclined position.
In accordance with another presently preferred embodiment, said
resilient body is provided with two edges each disposed adjacent
another side of the patient. First and second inflatable bodies,
which are independently inflatable, are connected along the two
edges. In this manner, selectively inflating or deflating the
inflatable bodies on one or the other side of the patient permits
the patient to be fully turned or be supported in intermediate
inclined positions facing one or the other direction.

DESCIPTION OF THE PREFERRED EMBODIMENTS
Reference is now made to the drawings, wherein identical or similar
parts have been designated by the same reference numerals
throughout, and first referring to FIGS. 1-3, there is shown a
useful aid for hospitals or the like consisting of a body-turning
device 10. In a preferred embodiment as illustrated herein, the
device 10 is fabricated of plastic, such as vinyl or of elastomeric
coated materials, and includes, as best illustrated in FIGS. 1, 2,
two main parts, namely, a non-inflatable resilient body 12 which is
that portion delineated by an undulating free edge 12a and a
substantially straight heat seal line 12b, and a remaining
inflatable portion 14 consisting of a large first inflatable body
14a and a second smaller superposed inflatable body 14b.
Specifically, the resilient body 12 is formed by upper and lower
vinyl panels 12c, 12d, heat sealed or adhesively bonded together to
form an enclosure for an appropriately shaped internal member 12e
which is preferably fabricated of hard rubber, cellular rubber or
other such resilient material.
Turning now to the construction of the inflatable body portion 14,
the previously noted vinyl panels, 12c, 12d also cooperate with two
additional intermediate panels 14c, 14d, respectively, to form the
previously noted first and second inflatable bodies 14a and 14b.
For reasons which will soon be apparent, only the inflatable body
14a has a main inlet connection 16 for pressure air, preferably
supplied by a compressor or similar mechanical means, whereas
inflation of the second inflatable body 14b is achieved by
controlled passage of pressure air, as best shown in FIG. 3, from
the inflated body 14a through valve openings 18 and 20 into the
inflatable body 14b. The pressure air during passage between these
bodies 14a, 14b is channeled through the valve openings 18 and 20
by an accordion-folded enclosure panel 22 which is appropriately
heat sealed to the facing vinyl panels 14c, 14d around the valve
openings 18, 20.
The significance of the structural features of the body-turning
device 10 as has just been described will be better appreciated
when considered in conjunction with the following description and
illustrations, as set forth in FIGS. 4-8, of the manner in which
the device 10 is effective in causing the turning of a lying
patient P, who, it will be assumed, for health reasons must be
turned very carefully and gently and, for the same health reasons,
cannot be expected to significantly assist in this maneuver. It is
contemplated that the nurse or hospital orderly can, without too
much effort or difficulty, raise the patient P sufficiently so that
the resilient body 12 can be placed beneath the patient's shoulder
and buttocks, all as clearly illustrated in FIG. 4. Since the
patient P only has the shoulder and buttocks resting on the
resilient body 12, the medial portion of body 12 which thus
performs no function may be removed to result in the undulated
shape of the edge 12a.
Next, pressure air is channeled through the inlet 16 causing
inflation of the first inflatable body 14a and has two significant
consequences: first, the inflation of the body 14a elevates the
portion of the resilient body 12 adjacent to and connected to it,
all as is clearly illustrated in FIG. 5, and thus effectively
raises one side of the patient P to the extent of the clearance C;
seconds, the inflated condition of the inflatable body 14a
advantageously presents the upper panel or wall -d of this body in
an elevated position and as structure against which further
pressure can be brought to bear in the body-turning maneuver. In
this connection, it should be apparent that not all body-turning
maneuvers occur in exactly the same way, but nevertheless, these
maneuvers do successfully occur, despite slight variations, and are
the result of use of the elevated wall 14d as appropriate structure
against which to exert pressure. Further, by comparison of FIGS. 5
and 6, it will also be noted that the inclination of the wall 14d
appropriately changes so that in progressive positions of movement
of the patient P the wall 14d essentially assumes a position
beneath the patient P (as illustrated in FIG. 6) such that the
second inflatable body 14b can be advantageously inflated against
the then appropriately oriented wall 14d this being effective in
exerting a pushing pressure against the patient P. More
particularly, upon continued introduction of pressure air into the
inflatable body 14a, a point is ultimately reached where there is
controlled passage of some of the pressure air from the inflated
body 14a through the previously noted valve openings 18, 20 into
the second inflatable body 14b, the introduction of such pressure
air being effective, of course, to start causing the inflation of
the second inflatable body 14b. Thus, the condition of the device
10 progresses from that shown in FIG. 5 to that shown in FIG. 6
wherein the inflating body 14b starts to expand between the
elevated wall 14d and the patient P with the result that there is a
significant lifting of the side of the patient P in contact with
the device D.
As intended to be illustrated in the progressive diagrammatic views
of FIGS. 7, 8, ultimately there is an extent of inflation of both
of the inflatable bodies 14a, 14b that the patient P is lifted to
an extent that he is lying only on one side and is then able to
reach out with one of both of his hands, make contact with the bed
B, and thereafter gently ease himself back down in contact with the
bed and, in the process, complete a body-turning maneuver.
As described above, air under pressure is channeled into the inlet
16 to result in inflation of the first and second inflatable bodies
14a 14b. Referring to FIG. 9, presently preferred embodiment of the
invention includes a pneumatic control device 24 for selectively
inflating and deflating the inflatable bodies 14a and 14b to a
desired level of pressure. Clearly, while the above described
device can be utilized for fully turning a patient, the same device
may be utilized to support a patient in an intermediate inclined
position, such as suggested in FIGS. 5-7. To maintain a patient P
in one of the latter positions, it is necessary that the air
pressure within the inflatable bodies 14a and 14b be maintained at
an appropriate level. The pneumatic control device 24 permits
selective control of the air pressure within the inflatable bodies
and, accordingly, the precise orientation of the patient.
The pneumatic control device 24 includes a supply of air under
pressure 26 and an output line 28 which is connected to the inlet
16 of the inflatable body 14a. A supply line 30 is connected to the
air supply 26 and an inlet air valve 32 is provided between the
output line 28 and the supply line 30. The inlet valve 32 is
advantageously a fluidic air pilot three-way air valve. Such valves
are conventional and, as will become clear to a person skilled in
the art, other equivalent valves may be utilized since the precise
type of valve used is not critical for the purposes of the present
invention.
The pneumatic control device 24 advantageously includes a check
valve 34 which permits flow of air only from the inlet valve 32
towards the output line 28, but not in a reverse direction. The
reason for the check valve 34 will become evident from the
description that follows. Also connected to the supply line 30 is a
valve control line 36. The air pressure in the valve control line
36 is maintained at the same pressure as that in the supply line
30.
The inlet air valve 32 includes inlet, outlet and control ports. A
fill control line 38 is provided between the valve control line 36
and the control port of the inlet air valve 32. Actuating means in
the form of a push button valve 40 is provided within the fill
control line 38. In this manner, depression of the fill push button
40 applies the air pressure within the valve control line 36 to the
control port of the inlet air valve 32 to shift the latter to an
operataive position wherein the supply line 30 is placed in fluid
flow communication with the output line 28. The air within the
supply line 30 continues to flow to the output line 28, and into
the inlet 16 of the inflatable chamber 14a, so long as the push
button 40 is maintained in a depressed condition. As soon as the
fill push button 40 is released, the inlet air valve reverts to the
position shown wherein the fluid flow communication between the
output line and the supply line is interrupted. At such time,
further air under pressure cannot be transmitted to the inflatable
bodies and a desired level of pressure may be achieved and
maintained within the bodies to cause the same to assume one of the
conditions illustrated in FIGS. 4-8. Clearly, this permits the
patient either to fully turn or be supported in an intermediate
inclined position. A pressure of less than the maximum supplied by
the supply 26 may be obtained within the inflatable bodies by
releasing the fill push button 40 before filling is completed as
suggested in FIG. 8.
The pneumatic valve device 24 also includes a fluidic air control
three-way air valve 42 which is similar in construction to the
inlet air valve 32. Both air valves 32 and 42 are normally in their
closed or inoperative conditions. The valve 42 is also connected to
the output line 28.
An exhaust control line 44 is connected to the valve control line
36 and an exhaust actuation means 46 is provided within the exhaust
control line 44. The exhaust actuation means 46 is similar to the
actuation means 40 in the fill control line and is also
advantageously in the form of a push button valve.
When the push button valve 46 is depressed, the air pressure within
the valve control line 36 is transmitted to the control port of the
valve 42 to shift the same to an operative position wherein the
output line 28 is placed in communication with the atmosphere. In
this manner, air under pressure within the output line 28, and
within the inflatable bodies 14a and 14b, may be evacuated into the
atmosphere by suitable actuation of the air valve 42. Evacuation of
air from the inflatable bodies continues so long as the push button
46 is depressed. The pressure within the device 10 may be reduced,
not necessarily to zero, by depressing the push button until the
desired level is reached, and then releasing it. In this manner,
the patient may be moved from a more inclined to a less inclined
position, such as, for example, from the position shown in FIG. 6
to a position shown in FIG. 4 or 5.
The device 10 described above is clearly suitable for orienting the
position of a patient without initially fully raising the patient.
The resilient body 12 need only be partially disposed beneath the
shoulders and buttocks of the patient. While the device 10 has been
illustrated in FIGS. 4-7 as being disposed on one side of the
patient P for orienting the patient in one direction, clearly the
device 10 can be disposed along the other side of the patient for
turning or orienting the patient to the other side. As viewed in
FIGS. 4-7, the patient P is turned in a counter-clockwise
direction. As suggested above, the device 10 can likewise be
utilized to turn the patient in a clockwise direction by merely
placing the device along the other side of the patient.
Referring to FIG. 10, a patient orienting device 10' is shown which
is suitable for use where a patient is to be frequently turned or
oriented from side to side. The device 10' includes a resilient
body 12' which differs from the resilient body 12 shown in FIG. 1
in that two straight lines 12b and 12b' are provided which are
spaced from each other to be positionable along or adjacent
opposing sides of a patient P. The device 10' includes additional
first and second inflatable bodies 14a' and 14b' which are
similarly constructed and connected as the bodies 14a and 14b. An
inlet connection 16' is provided for the inflatable body 14a'
similarly as the inlet connection 16 is provided for the body 14a.
In essence, the device 10' is very similar to the device 10 in FIG.
1, with the exception that two opposing similar or identical sets
of inflatable bodies are provided at the lines 12b and 12b'.
Advantageously, the inlet 16 is utilized to inflate the bodies 14a
and 14b while the inlet 16' is utilized to inflate the bodies
14a'and 14b'.
The uses and operation of the device 10' is similar as that
described in connection with the device 10. However, as best
depicted in FIGS. 12-14, the device 10' is disposed with the
resilient body 12' below the patient P. In this manner, the edges
or lines 12b and 12b' extend substantially adjacently to the sides
of the patient P. As opposed to the device 10, the device 10' must
be placed beneath the patient P before the latter reclines on the
rest surface or bed, or the patient P must be lifted. For this
reason, the device 10' may be placed on the rest surface before the
patient P reclines thereon. Alternately, the device 10' may be
incorporated into the rest surface and form a permanent part
thereof.
In the use of the device 10', since two inlet connections 16 and
16' are provided, either a single pneumatic control system or two
parallel systems may be utilized. Where a single control device
such as the device 24 is utilized, the output line 28 may be
selectively connected to one or teh other of the inlet connections
16 or 16'. It is also possible, clearly, to provide two separate
independent pneumatic control devices 24 each with a corresponding
output line 28 thereof connected to one of the inlet connections of
the device 10'.
Referring to FIGS. 12-14, the inflatable bodies 14a and 14b are
shown to be increasingly inflated to continuously shift the
orientation of the patient P in a counter-clockwise direction
similar to the manner shown in FIGS. 4-7. However, the device 10'
enjoys the versatility that shifting the patient P in the other
direction is easily accomplished without raising the patient or
shifting the device 10' by simply filling the inflatable bodies
14a' and 14b' as shown in FIGS. 15 and 16. As the device 10 shown
in FIG. 1, the device 10' permits selective orientation of the
patient P as well as turning in the manner described above.
Although the devices 10 and 10' have been described as useful aids
in turning hospital patients in bed, it will be appreciated that
the use thereof is not strictly limited to this purpose but can
include, for example, turning of a patient onto a stretcher, or
some other similar body turning maneuver which may require care in
its execution.
Numerous alterations of the structure herein disclosed will suggest
themselves to those skilled in the art. However, it is to be
understood that the present disclosure relates to a preferred
embodiment of the invention which is for purposes of illustration
only and is not to be construed as a limitation of the
invention.
