PATIENT ORIENTING DEVICE 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 patients size makes 2 tient 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. Atleast a portion of said second inflatable body is at least partially 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 US. 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. Al-.
ternately, the present invention may be incorporated within a bed or rest surface upon which a patient is disposed. With the latter em bodiments, 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 pasupported 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 bodiesare 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 independentlyinflatable. 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 v the otherdirection.

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. l-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. I, 2. two main parts, namely, a noninflatable 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 14h.
Specifically. the resilient body 12 is formed by upper and lower vinyl panels 121'. l2d. heat sealed or adhesively bonded together to form an enclosure for an appropriately shaped internal member l2e 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, l2d also cooperate with two additional intermediate panels 14c. 14d. respectively. to form the previously noted first and second inflatable bodies 140 and 14b. For reasons which will soon be apparent, only the inflatable body 140 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 140 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 accordionfolded 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 1 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 patients 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 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 -a' 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 144! this being effective in exerting a pushing pressure against the patient F. More particularly, upon continued introduction of pressure air into the inflatable body 14a, :1 point is ultimately reached where there is controlled passage of some of the pressure air from the inflated body 140 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 140, l4b 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 I6 to result in inflation of the first and second inflatable bodies 140 l4b. Referring to FIG. 9, presently preferred embodiment of the invention includes a pneumatic control device 24 for selectively inflating and deflating the inflatable bodies 140 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 140 and 14b be maintained at an appropriate level. The pneumatic control device 24 permits selective control of the airpressure 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 140. 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 ofa 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 till 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. I in that two straight lines 1212 and 12b are provided which are spaced from each other to be positionable along or adjacent opposing sides of a patient P. The device It) includes additional first and second inflatable bodies and 14b which are similarly constructed and connected as the bodies 14a and 14!). 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. I, 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 l4a'and Mb.
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. l2l4, the device 10' is disposed with the resilient body 12' below the patient P. In this manner, the edges or lines 12b and l2b' 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 enjoys the versatil ity 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 14!) as shown in FIGS. 15 and 16. As the device l0 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.
