METHOD FOR PLACING A PATIENT SUPPORT DEVICE IN A VASCULAR POSITION
There is provided a backrest pivoting system having a backrest and an actuator for pivoting the backrest. The actuator is pivotably connected to the backrest by a pivot defining a first pivot axis. The backrest is configured to pivot about a guide member which defines a second pivot axis coaxial with the first pivot axis. There is also provided a backrest pivoting system including an actuator and a resilient member mounted in series with the actuator. There is also provided an extendable user support assembly comprising a lower body support panel and a core support panel supported by a frame, the lower body support panel being translatable relative to the frame such that an opening is created between the lower body support panel and the core support panel when the lower body support panel is translated away from the core support panel. There is also provided a method for placing a bed in a vascular position.

28 . A method for placing a patient support device in a vascular position, the patient support device having a patient support assembly mounted onto a frame having a head end and a foot end, the patient support assembly including a backrest located near the head end, a lower body surface located near the foot end and a core body surface located between the backrest and the lower body surface, the core body surface being pivotably interconnected to the lower body surface, the method comprising:
receiving a command to place the patient support device in the vascular position;
pivoting the core support panel at a thigh angle above the frame;
pivoting the lower body support panel at a lower body angle above the frame;
pivoting the backrest at a back angle above the frame; and
tilting the frame at a tilt angle relative to the horizontal such that the head end of the frame is located below the horizontal, said pivot angle being within a predetermined range of said foot angle, thereby placing the patient support device in the vascular position.
29 . The method as claimed in claim 28 , wherein pivoting the core support panel comprises raising a rear portion of the core support panel located towards the lower body support panel.
30 . The method as claimed in claim 29 , wherein raising the rear portion of the core support panel further comprises raising a front portion of the lower body panel located towards the core support panel, the rear portion of the core support panel being hingeably connected to the front portion of the lower body panel via a hinge connection.
31 . The method as claimed in claim 30 , wherein raising the rear portion of the core support panel and raising the front portion of the lower body panel comprising actuating a lower body actuator having a first portion pivotably connected to the frame and a second portion pivotably connected to the hinge connection.
32 . The method as claimed in claim 28 , wherein the tilting of the frame is performed after the raising of the core body support panel and the raising of the backrest.
33 . The method as claimed in claim 28 , wherein the raising of the core body support panel, the raising of the backrest and the tilting of the frame are performed simultaneously.
34 . The method as claimed in claim 28 , wherein the core angle is 30 degrees, the lower body angle is 13 degrees, the back angle is 13 degrees and the tilt angle is 13 degrees.
