Hospital bed height limiting system

A bed comprising:

• a frame;
• a patient receiving surface for receiving a patient thereon, the patient receiving surface being supported by the frame, an elevation mechanism secured to the frame and to the patient receiving surface for moving the patient receiving surface vertically relative to a ground surface on which the bed is placed;
• a bed height limiting system for limiting a height of the patient receiving surface to a minimum height relative to the ground surface, the bed height limiting system comprising:
• a height sensor;
• a processing unit operatively connected to the elevation mechanism and the height sensor;
• and
• a user interface operatively connected to the processing unit,
• wherein the processing unit is operable to:
• receive an indication of a minimum height provided by a user via the user interface;
• receive, from the height sensor, an indication of a current elevation mechanism height;
• determine, based on the indication of the current elevation mechanism height, a current bed height;
• and
• in response to the current bed height being equal to the minimum height:
• provide a stop command to the elevation mechanism to stop a downward movement of the elevation mechanism.
