ABSTRACT:
Guard rail actuated safety apparatus (42, FIG. 1; 89, FIGS. 5A and 5B) is operative to prevent simultaneous lowering of both of a pair of guard rails (26, 28) to inoperative positions in which they are ineffective to prevent a patient from falling off the edge of a patient support assembly 12. In one embodiment, the guard rails are secured together by a cable (44) which holds the guard rails against concurrent lowering. In an electromechanical embodiment, a controller (89, FIG. 5) senses the guard rail (26, 28) position, and blocks the lowering of either guard rail (26, 28) whenever the other is lowered. In addition, or alternatively, the controller (89) actuates a brake 146, sounds an alarm (136), raises the guard rails (26, 28) after a time delay (158), deactuates a drive motor (118) for a movable or adjustable patient support assembly (12) or releases air from a pneumatic mattress (12A'). An attendant detector (141, 143, 138, 140 ) overrides actuation of the selected alarm condition responsive apparatus (146, 148, 150, 152, 154) and rail latch actuators (93, 95, 91, 97) when an attendant is detected alongside the bed (8).
