In an ideal world, the sizes of medical equipment be standardized, and have bays in the bed that they plug into, with the bed providing power. This would keep the tube and cable lengths short, and you could have a guard around the bed to keep people from accidentally leaning on the tubes or pulling them out. The control consoles would have to be external to the module though, as you don't want visiting kids (or knees) pushing shinny buttons under grandmas bed. Having the control panels be remote would help reduce the number of people needed to be next to the person, giving the people who are directly operating on the patient more room. This would also make patent transport easier, as you would no longer need a army of people to help move all the equipment keeping the patient alive or the possible errors that can be introduced by disconnecting and reconnecting the equipment.
