Detailed Description of the Drawings Referring now to the drawings, Figure 1 illustrates a bed 10 having a base 12 including opposite side members 14 and 16 and transverse members 18 and 20 extending between the side members 14 and 16. An assembly 22 is located at one end of the feet 24 of the bed 10. The support assembly 22 supports a patient support assembly 26 in a cantilevered shape. Therefore, the end of the head 25 of the bed 10 is open facilitating access to the patient (not shown). It is understood that in another embodiment of the present invention a support engages the end of the head of the base 12 to support the head end of the patient support assembly 26. Therefore,, the present invention is not limited to a cantilever design. The support assembly 22 is coupled to the base 12. The base 12 is supported by the rollers 18 which are illustratively secured. The support assembly 22 is movable up and down in the double head arrow direction 36 to raise and lower the height of the patient support assembly 26. The support assembly 22 can rotate the patient support assembly 26 on its longitudinal axis 38 as indicated by the double-headed arrow 40. The support assembly 22 can rotate the patient support assembly 26 in any direction for a total of 360 °. In other words, the patient can be rotated 180 ° to tilt the patient to assist in respiratory diseases such as ARDS, or to perform surgical procedures or to allow the patient to lie face down on the support surface. The present invention allows a total 180 ° rotation of a patient located on a patient support surface while providing spinal stability for patients with spinal trauma. An incunable surface (not shown in Figures 1 and 2) is attached to the patient support assembly 26 before the patient support assembly 26 is rotated. The patient support assembly 26 includes a pair of horizontally extending support arms 42 and 44 which engage a cruciform shaped plate 46 of the support assembly 22. In the illustrated embodiment, the arms 42 and 44 extend apart of the support assembly 22 in a cantilever shape. A patient support surface 50 engages between the arms 42 and 44 as described below. The cruciform 46 engages a rotatable, annular hanger that is held in place on a front surface 58 of the support assembly 22 by means of the rotary supports that also engage the front surface 58. The cruciform 46 includes four arms that are each One insured to the ring hanger. A motor and gear are located on the support assembly 22. The gear engages the annular hanger to rotate the annular hanger relative to the front surface 58. Therefore, the support arms 42 and 44 coupled to the cruciform also rotate in the direction of the double headed arrow 40 in Figure 2. The details of the support assembly 22 are described in PCT International Publication No. WO 99/07320 which is incorporated herein by reference. The patient support surface 50 includes an external frame 56 and the plurality of panels 58-65 which rotationally engage the external support frame 56 by the rotary connections 66. In the illustrated embodiment, the panels 58-65 are all ascending or descendingly rotatable on opposite sides of the outer frame 56. This rotatable movement of the panels 58-65 provides access to the patient when in the inclined position. The portions of the panels 58-65 are spaced apart from the outer frame 56 to provide manual access to hold the patient support surface 50 during transport. In other words, the openings or slots in the panels 58-65 define the attachment locations 68 for the patient support surface 50. The patient support surface 50 is designed to be used in the field in an injury situation to transport to a patient in the manner of a booster table or stretcher. The support surface 50 is then mounted on the bed 10 without having to move the patient out of the surface 50. The bed 10 includes the securing mechanisms 70, 72, and 74 for a head panel, a seat panel, and leg panel, respectively, of the patient support surface 50. When the patient support surface 50 is carried to the bed 10, it is lowered between the side arms 42 and 44 as shown by the arrows 52 in the Figure 3 and is automatically secured by the securing mechanisms 70, 72, and 74 that couple the outer frame member 56 as described below.

The patient support surface 50 includes external connecting frame member 76 between the head section including the panels 58-61 and the seat section including the panels 62 and 63. The hinge connections 76 are also provided between the panels 62 and 63 and the leg section that includes the panels 64 and 65. The hinge connections 76 are best illustrated in Figure 5. The hinge connections 76 are covered with the slide fastening cylinders 78 during transportation to prevent the rotational movement of the patient support surface 50. The cylinders 78 are shown in a closed position in Figures 1, 2 and 4, illustratively, the locking cylinders 78 are tilted to the closed position by a spring 80. The Figures 5 and 6 illustrate the cylinders 78 in the open positions so that the hinges 76 are exposed to allow articulation between the adjacent head, the seat and the foot sections of the surface of Patient support 50. The patient support surface 50 is mounted on the bed 10 with the cylinders 78 in the closed position. As shown in Figure 10, the fasteners 81 of the securing mechanism 70 couple a portion of the outer frame 56. The fasteners 82 of the securing mechanisms 72 engage the cylinders 78 between the head and seat sections of the patient support 50. The fasteners 84 of the securing mechanisms 74 couple the cylinders 78 between the seat section and the foot sections of the patient support surface 50. The hydraulic cylinders 86 and 88 are coupled to the securing mechanisms 72 and 74, respectively , as best shown in Figure 6. The cylinders 86 and 88 are located within the frame members 42 and 44 on each side of the bed 10. The cylinders 86 are activated to move the fasteners 82 toward the end of the foot 24. of the bed 10. The movement of the fasteners 82 causes the movement of the locking cylinders 78 apart from the hinges 76 located between the head section and the seat section of the patient support surface 50 to allow articulation of the head section of the patient support surface 50. Similarly, the cylinders 88 are activated to move the fasteners 84 to the end of the head 25 of the bed 10. One movement causes the locking cylinders 78 to move toward the end of the head 25 and exposes the hinges 76 between the seat section and the foot section of the patient support surface 50 to allow articulation of the foot section. . The cylinders 86 and 88 can be activated automatically in the installation of the patient support surface 50 in the bed 10. On the other hand, the cylinders 86 and 88 are activated only when the articulation of the patient support surface 50 is initiated. In this case, the cylinders 86 and 88 store the fastening cylinders 78 on the hinges 76 until the articulation is initiated. Additional details of the hinges 76 are illustrated in Figure 5. The hinge includes a slit 75 formed in a first frame portion 56 and a tongue 77 formed in a second portion of the frame 56. A pivot pin 79 extends through the slit 75 and the tongue 77 so that the hinge 76 rotates about the axis 83. The insulators 81, 82 and 84 include the first and second securing portions 85 and 87 as shown in Figure 5. The securing portions 85 and 87 include guide ramp surfaces 89 and 91, respectively, for the fasteners to open automatically during insertion of the patient support surface 50. In another embodiment, the fasteners 81, 82 and 84 are opened by an upward movement of the patient. transfer surface 170. Other configurations of insurers 81, 82 and 84 are illustrated in Figures 7 and 8. As best illustrated in Figures 1, 2 and 9, each one of the support arms 42 and 44 includes foot end sections 100 and end sections of the head 102 that rotatably engage the foot end sections 100 through the rotatable sections 104. The plates 106 are rigidly engaged. to the end sections of the head 102 by means of the fasteners 108. The plates 106 are formed to include the arcuate grooves 110 that slide over the bolts 112 coupled to the foot end sections 100 of the arms 42 and 44. Thus, the end sections of the head 102 can be rotated upwardly relative to the foot end sections 100 to elevate the head end of the bed. A cylinder 114 is rotatably coupled to each foot end section 100 of the arms 42 and 44 through a rotatable connection 116 shown in Figure 9. Cylinders 114 include pistons 118 that rotatably engage the end sections of the cylinder. head 102 of the side arms 42 and 44. When the pistons 118 are in the extended position shown in Figure 9, the head end sections 102 and the foot end sections 104 of the arms 42 and 44 are generally parallel. When the piston 118 retracts, the end sections of the head 102 rotate upwardly as shown in Figure 9 to raise the end of the head of the bed 10 in the direction of the arrow 120 of Figure 8. drive and internal frame 121 is provided, if desired to move the foot section of the patient support surface 50 downwardly in the direction of the arrow 122. As discussed above, the panels 58-65 of the support surface of patient 50 are rotated relative to outer frame 56. Figures 11 and 12 illustrate another embodiment of a head support mechanism including a fixed member 130 extending between opposite sides of frame 56 and a rotatable head portion. 132. The head portion 132 is rotatable externally relative to one end of the head of the frame 56 when the fastener 126 is activated as illustrated by the arrow 133. Figure 11 illustrates a release plate. 126 is to be pushed inwardly toward the center of the patient support surface 50 in the direction of arrow 128 to release the panel 131 for rotational movement. This reduces the likelihood that the securing mechanisms 126 are inadvertently activated by a caregiver during transport. Another type of release mechanism is a pushbutton release mechanism 135 illustrated in Figures 11-13. The pressure button 135 is located at an angle relative to the frame member 56 so that the pressure button 135 does not activate when the patient support surface 50 rests on the floor. The pressure button 135 is pressed in the direction of the arrow 137 to release a panel 60 to rotationally move in the direction of the arrow 139 in Figure 12. A spring 141 biases the pressure button 135 to the fixing position of the Figure 12 when an opening 143 formed in the panel 60 is aligned with the push button 135. Figure 13 illustrates the panel 60 in a downwardly rotated position. It is understood that any type of securing mechanism 126, 135 can be used with any of the panels of the patient support surface 50. Figures 14 and 15 illustrate a line control apparatus 144 configured to be attached to one end of the head of the outer frame 56. Illustratively, the line control apparatus 144 includes, a foam body 146 formed to include upper grooves 148 adjacent an upper edge 149 and openings 150 for rotating the IV pipes or other hoses / pipes 152, 154 to the of the patient as shown in Figure 15. A bracket 156 engages the body 146. The bracket 156 is illustratively a C-shaped bracket configured to engage the frame 56. Each of the panels 58-65 of the support surface of the Patient 50 is covered with a pressure reducing surface such as foam 158, etc., and a cover 160 as shown in Figure 16. Figure 17 illustrates an elastic material 162 as Spandex that is filled with pellets of styrofoam 163 or obro material. This elastic material 162 is illustratively positioned within an outer cover 164 that has an air exhaust control and that holds its shape for a predetermined amount of time. The outer cover 164 allows the inner elastic bag 162 of styrofoam pellets 163 to conform to the shape of the patient. In a modality, the outer cover 164 or the inner bag 162 formed to include a heating element made of, for example, a strong heating element such as the Gorix ™ material. A controller (not shown) is coupled to the heating element. The heating material is used to heat the patient on the patient support surface 50. Various combinations of bags 162 and 164 placed on the foam or contoured foam may be used in each section 58-65 of the patient's support surface. A movable transfer surface 170 is illustratively coupled to the base 12 as shown in Figures 1 and 2. The surface 170 rises upwardly when the patient support surface 50 is mounted on or removed from the bed 10 by a suitable lifting mechanism 72 coupled between the surface 170 and the base 12. The lifting mechanism 172 is any conventional lifting mechanism such as an articulated scissors lift mechanism, articulated parallelogram mechanism, etc. The surface 170 moves upward in the direction of arrow 174 in Figure 2 and can support the patient support surface 50 if the securing mechanisms fail. If desired, the surface 170 may remain in its upwardly rising position, elevated below the patient support surface 50, except during patient rotation, when the surface 170 is to be lowered. As discussed above, surface 170 may be used to open insurers 81, 82 and 84.

When it is desired to rotate the patient to move it to an inclined position, an appropriate incunable surface is placed on the patient. The incunable surface engages to be adjacent to the arms 42 and 44. Figures 18 and 19 illustrate an embodiment of the incunable support surface. In this embodiment, the externally registered side bars 176 are rotatably coupled to support the arms 42 and 44. The side bars 176 include an external frame member 178 and an internal member 180 rotatably coupled to an upper bar 182 of the frame member 178. The side bars 176 move to a low position illustrated by the coupled side bars to support the arm 44 in Figure 18. The side bars 176 also move to a raised position illustrated by the other side bars 176 coupled to the arm 42 in the Figure 18. After the side bars 176 are in the raised position, the central portions 180 are rotatably on a patient on the patient support surface 50 as shown in Figure 19 to provide an inclined support surface. A suitable surface for supporting the patient's head and body (not shown) is attached to the sections 180 on the patient. The searchers may be provided, if necessary, to jointly secure the members 180 located on opposite sides of the bed 10 for tilting.
