BACKGROUND AND SUMMARY OF THE INVENTIONThis invention relates to patient restraints and in particular to enclosures for beds in care giving facilities which restrict a patient's activities to the bed while allowing free movement of the patient within the bed.
Many patients in health care facilities suffer from mental or physical conditions which require that they be restricted to their beds for their own and others' safety. Generally, patients that require restraints are non-cognizant, injury prone, or excessively active as in the case of seizure patients. Patients who present aggressiveness, cognizant impairment, susceptibility to falls, and night time confusion are likely candidates for restriction. One commonly practiced restrictive procedure is to provide such patients with a full-time sitter who can prevent the patient from attempting to leave the bed or move about the room. This, of course, can result in a substantial increase in the health care costs resulting from increased labor charges. Alternatives to a full-time sitter are physical or chemical restraints which inhibit patient movement from the bed. Physical and chemical restraints can adversely affect the physical and mental condition of a patient being so restrained which can inhibit healing.
An alternative restrictive procedure is to provide a bed enclosure which allows free movement of the patient within the bed but prohibits the patient from leaving the bed. Patients diagnosed with Alzheimer's disease, closed head injuries, neurological defects, and strokes often benefit from bed enclosures as they are protected from injury caused by bed falls, entrapment in side rails, and accidents occurring while wandering from the bed. Presently available bed enclosures are typically free-standing mesh type cages with zippered flaps which may be unzipped and thrown on the roof of the enclosure to allow caregiver access to the patient. Such enclosures inhibit movement of the bed to a different location, interfere with the articulation of the bed, interfere with raising and lowering the bed, interfere with medical devices being used to provide care to the patient (especially drainage devices such as foley catheters from which the patient must be disconnected to exit the bed enclosure), interfere with the patient's control of the bed, and/or are difficult for the caregiver to configure so that care can be provided to the patient.
Caregivers in health care facilities would welcome a patient restraint system which provides the patient with free movement within the bed but limits the patient's movement to the bed yet allows movement of the bed from location to location, height adjustment of the bed, and articulation of the bed by the patient and caregiver. Health care facilities and caregivers would also welcome a bed enclosure which would not inhibit the use of medical devices necessary for providing patient care and is configurable to provide only the restraint necessary for the particular patient.
According to the present invention, the bed enclosure includes a series of sidewalls extending upwardly from the bed frame and a roof. At least one sidewall of such bed enclosure includes a vertically adjustable curtain which is configurable between a closed position, an open position, and a plurality of intermediate positions. The curtain includes a top fastener for securing the curtain in the closed position. In preferred embodiments the bed enclosure is mounted to the frame of the bed.
According to the present invention, a bed enclosure for use with a hospital bed having a frame, an intermediate frame vertically adjustable relative to the frame, an articulating deck pivotally mounted to the intermediate frame, and a mattress, comprises a shell and a skeletal structure supporting the shell and being attached to the intermediate frame of the bed. The shell includes a roof, a bottom panel, a wall connected to and extending between the bottom panel and the roof, and a curtain formed in the wall. The curtain is movable relative to a remainder of the wall between a lowered position to form an opening providing access between the interior and exterior of the shell and a raised position in which the shell forms a complete enclosure. The bottom panel of the shell may rest on and extend across the articulating deck with the mattress resting on the bottom panel while the curtain is movable between the lowered position in which a top edge of the curtain is below a top surface of the mattress of the bed to which the bed enclosure is attached and the raised position in which the shell forms a complete enclosure within which the mattress is received. The enclosure may include an intravenous (“IV”) slot formed in the wall of the shell adjacent to the movable curtain to allow a patient with an IV attached to enter and exit the bed to which the shell of the bed enclosure is attached without removal of the IV from the patient. Closure of the shell may be accomplished with a zipper having a first row of teeth attached to the top edge of the curtain and a second row of teeth attached to the remainder of the wall so that the zipper secures the top edge to the remainder of the wall when the curtain is in the raised position. A sensor for producing an illumination signal when the zipper is not fully closed and a light coupled to the shell which is illuminated when the sensor produces the illumination signal may also be provided. The skeletal structure may include telescoping cross-members configured to alter the length of the skeletal structure in response to an alteration in the length of the intermediate frame.
According to another embodiment of the present invention the bed enclosure for use with a hospital bed to restrain movement of a patient includes a shell located over the bed to restrain the patient, a timer coupled to the shell, and a reset button for reinitializing the timer. The timer may count up from zero each time the reset button is pressed.
A bed enclosure for use with a hospital bed to restrain movement of a patient in accordance with the present invention includes a shell having a side wall, an access curtain, and a zipper for securing the access curtain to the side wall so that the enclosure is in a closed state, and a light indicating the state of the enclosure. The enclosure may include a sensor for producing an illumination signal when the zipper is not fully closed and a light coupled to the sensor so that the light is illuminated when the sensor produces the illumination signal. The enclosure may include first and second opposite side walls, each side wall including an access curtain coupled to the side wall by a zipper, and first and second lights located adjacent the first and second side walls to indicate the state of the enclosure and first and second sensors located adjacent the first and second zippers for producing illumination signals when the zippers are not fully closed, the first and second lights being coupled to each of the first and second sensors so that both the first and second lights are illuminated when either of the first or second zippers is open.

BRIEF DESCRIPTION OF THE DRAWINGS
When a hospital bed enclosure 10 in accordance with the present invention is fully closed patients are restricted to their beds but are allowed free movement therein. Bed enclosure 10 prevents bed falls, patient entrapment in side rails, and unsupervised wandering of the patient. Illustratively, bed enclosure 10 is made of a combination of vinyl, mesh, and clear plastic segments forming a complete enclosing shell 26 which is provided a box-like shape and stability by a skeletal structure 28. Bed enclosure 10 is configurable to allow caregivers to attend to patients with a reduced risk of injury of the patient or injury of the caregiver by the patient.
Bed enclosure 10 is designed so that skeletal structure 28 is mounted to intermediate frame 12 of a bed 14 having an articulating deck 16 so as not to inhibit vertical adjustment of bed 14, relocation of bed 14, or reconfiguration of articulating deck 16. When fully closed as shown in
Referring now to
Bed enclosure 10 includes a shell 26 and a skeletal structure 28 to provide shape to shell 26. Shell 26 includes a bottom panel 30, two side walls 32, a head end wall 34, a foot end wall 36, and a top wall or roof 38. Skeletal structure 28 includes four vertically oriented support posts 40, two longitudinally extending cross members 42, and cross support 44. Illustratively skeletal structure 28 is formed from aluminum to provide a rigid lightweight skeletal structure 28, but it should be understood that other materials such as composites, fiberglass, wood, metal and the like may be used within the scope of the invention. As shown, for example, in
Rather than mounting bed enclosure 10 to the floor by separate stands surrounding bed 14, which would inhibit movement of the bed 14, bed enclosure 10 is directly mounted to intermediate frame 12 of bed 14. Prior to attaching bed enclosure 10 to bed 14, mattress 18 is removed from articulating deck 16. Support posts 40 are configured to be removably attached to intermediate frame 12 so that bottom panel 30 of shell 26 rests on deck 16 and extends across deck 16 below mattress 18. Illustratively, intermediate frame 12 includes four sockets 46 located near the four corners of frame 12 and is vertically adjustable relative to main frame 48. Sockets 46 are typically provided on hospital beds 14 to allow for attachment of traction mechanisms, IV stands and the like to bed 14. The illustrated bed enclosure 10 is configured to take advantage of the presence of sockets 46 to provide an attachment location for bed enclosure 10. Illustrated sockets 46 are tube sections extending vertically from intermediate frame 12, consequently posts 40 are configured to include an outside diameter which is slightly less than the inside diameter of socket 40 so that lower end of support posts 40 are received within sockets 46 when bed enclosure 10 is attached to bed 14 as shown, for example, in
Vertically oriented support posts 40 extend upwardly from intermediate frame 12 and connect at the top to cross members 42 which are connected together by cross support 44 forming skeletal structure 28 of bed enclosure 10. Some hospital beds include intermediate frames that are configured to vary in overall length to facilitate articulation of the articulating deck. While the illustrated embodiment of bed enclosure 10 refers to one-piece cross-members 42, it is to be understood that cross-members 42 may be formed from two or more separate components telescopically connected to each other to adapt the bed enclosure 10 for use with a bed having a frame that varies in length during articulation of the deck.
Shell 26 is supported by skeletal structure 28 and consists of multiple segments. In the vicinity of support posts 40 and cross members 42, shell 26 is formed from vinyl or plastic material providing a durable material at the point of contact of shell 26 and skeletal structure 28, as shown, for example, in
Side walls 32 include a side wall portion 62 of durable segment 54, two upright durable segments 64, bottom durable segment 66 extending across the bottom of side wall 32, and a mesh curtain 58 which may be raised or lowered as shown, for example, in
Sides 70 of mesh curtain 58 include handles 72 which run on vertically extending rods 74 connected to upright durable segments 64. Handles 72 on either side 70 of mesh curtain 58 can adjust the height of mesh curtain 58. Handles 72 include releases 76 which disengage stop mechanisms (not shown) which maintain handles 72 in user selected positions relative to rods 74. Sides 70 of mesh curtain 58 ride on rods 74. Each side 70 of mesh curtain 58 can be adjusted on its own from the beginning to the end of its range of motion before beginning to adjust the other side, as shown, for example, in
The adjustable height of mesh curtain 58 can be a benefit to the patient and caregiver by providing a method to keep the patient partially enclosed. For instance, when mesh curtain 58 is in a partially raised position, as shown for example in
A plurality of markings 78 are provided on both upright durable segments 64 of side wall 32 to provide a scale for adjusting the height of mesh curtain 58. The height adjustable mesh curtain 58 may be stopped at any location when being lowered and raised and is not required to stop at one of markings 78. Instead either handle 72 of mesh curtain 58 can be stopped anywhere in its range of travel by disengaging releases 76 of stopping mechanisms so that mesh curtain 58 can assume an almost unlimited number of adjustable rail configurations. Markings 78 simply provide a scale for aligning opposite sides of curtain if alignment is desired.
Upright durable segment 64 includes an IV slot 80 through which an IV tube 82 can be inserted without the need for removal of the IV from the patient. An insert 79 formed to include an internal slot 81 is received in a slot 83 in upright durable segment to provide rigidity to IV slot 80 as shown, for example, in
A zipper 102 is provided across top 68 of mesh curtain 58 and bottom 104 of sidewall portion 62 of durable segment 54 to secure mesh curtain 58 to sidewall portion 62 of durable segment 54 when mesh curtain 58 is in the fully raised state, as shown in
Side walls 32 also include a zipper 112 forming an access port 114 in mesh curtain 58 running along the length of bed enclosure 10 enabling the caregiver to quickly access the patient for normal care activities while providing the caregiver more protection from patient's inadvertent movements. The zippered access port 114 is shaped as a half oval to allow port 114 to be quickly and easily opened and closed. As is shown, for example, in
Patients whose conditions require restraint often require periodic observation. Bed enclosure 10 includes a resettable observation timer 118, as shown in
Hospital beds 14 are typically provided with side rails 20 which may be raised or lowered as needed. Side rails 20 include switches or controls 122 for controlling articulating deck 16 to allow the patient to reconfigure bed 14 for greater comfort, and also often contain controls 122 for in-room T.V.s and lighting as well as caregiver call buttons. Thus when the patient is in bed 14 side rails 20 are typically in the raised position to provide the patient access to controls 122 in side rail 20. Typically side rails 20 are lowered during patient transfer between bed 14 and another surface. Bed enclosure 10 is configured so that side rails 20 are on the exterior of bed enclosure 10 so that bed enclosure 10 does not inhibit raising and lowering of side rails 20.
Side rails 20 are typically attached to articulating deck 16 of bed 14 so that controls 122 located on side rail 20 are accessible to the patient even when bed 14 is in an inclined position, as shown, for example, in
In illustrated bed enclosure 10 not only is full head section articulation permitted, but other functions of bed 14 are facilitated because skeletal structure 28 is attached directly to intermediate frame 12 eliminating the need for a free standing bed enclosure base. Attaching bed enclosure 10 to intermediate frame 12 facilitates full use of the hi-lo functions of bed 14 as shown by arrows 144 in
Although illustrated bed enclosure 10 mounts to the intermediate frame 12 of bed 14 by inserting the lower portion of supports 40 in sockets 46, it is within the scope of the invention to attach enclosure to the frame of a bed with clamps, straps, brackets, and the like. Enclosure can also be attached to the frame of a bed that does not include a height adjustable intermediate frame or an articulating deck if those features are not required for treatment of a patient whose movements need to be restricted to the bed.
Foot end wall 36 includes an end wall portion 130 of clear segment 52 and a mesh segment 132 which are R.F. welded, or otherwise joined, to each other and to upright durable segment 64. Patient T.V. viewing is improved by replacing mesh with plastic at the foot end of roof 38 and at upper end of foot end wall 36, as shown for example in
Head end wall 34 includes a mesh segment 134 which is R.F. welded, or otherwise attached, to mesh segment 50 of roof 38 and durable upright segment 64 of side walls 32. Bottom panel 30 is typically formed of vinyl, polyester or other durable material which is R.F. welded, or otherwise attached, around the perimeter of the material to the bottom of side walls 32, head end wall 34, and foot end wall 36.
Bed enclosure 10 also includes mattress side cushions 136 which aid in maintaining a patient closer to the center of mattress 18. Illustrated side cushions 136 are fabric covered foam material and are configured with indentations 138 adjacent to the position of controls 122 on a raised side rail 20, as shown, for example, in
Foam pads 136 are enclosed in material 140 which includes a flap 142 which is connected to bottom panel 30 of bed enclosure 10 as shown, for example, in

In preferred embodiments, portions 450, 452, 456, 458 of each rail 444 are formed integrally and are bent into shape out of a unitary tubular element.
Rails 444 extend transversely away from bed 12 and are configured to be gripped by a patient entering and exiting bed 12. Illustrative rails 444 are fixed rigidly to collars 448 so as to be maintained at all times in their transversely extending positions. However, it is within the scope of the disclosure for rails 444 to pivot relative to collars 448 into longitudinally extending positions adjacent to the side of bed 12. In such an embodiment where rails 444 pivot, locking devices are provided to lock rails 444 relative to collars 448.
Another alternative embodiment bed enclosure, similar to bed enclosure 430, is shown in
IV port 460 is configured so that when members 466 are moved to a wide open position, such that the opening defined between members 466 is approximately the size of aperture 464, a bag or bottle 470 containing an IV solution is able to pass through aperture 464 and hook to a conventional IV pole 472 as shown in
Another alternative embodiment bed enclosure, which is also similar to bed enclosure 430, is shown in
Port 480 permits objects to be passed into and out of the interior region of bed enclosure 430 without having to open the large mesh flap portion of sidewall 436. Illustratively, a pendant controller 486 has been passed through port 480 and a cable 488 that couples pendant controller 486 to the main control circuitry of bed 12 extends from pendant controller 486 through port 480. Pendant controller 486 is of the conventional type and may include various user inputs well-known to those skilled in the art. Such user inputs may include buttons, knobs, or switches that control movement of portions of bed 12, that send a nurse-call signal, that control room lighting, and that control a television.
