In terms of use, regardless of the design of the tower, the main thing is nothing more than two major functions: first, fixing and positioning of relevant medical equipment. Please note that I have used the verbs "fix" and "position". To give two examples, such as the operating room anesthesia lifting tower, the anesthesia machine can be fixed in the tower, to ensure that the use of the process, the anesthesia machine is not randomly moving, and through the tower above the movement of the cantilever, you can position the anesthesia machine in the patient's head on the side of the side, to facilitate anesthesiologist's operation. Or some hospitals will be equipped with multimedia towers, the actual lifting tower on the fixed a display, through the lifting tower in the space on the movement, to locate the position of the display, to facilitate minimally invasive surgery; second, to provide the relevant medical equipment required for the supply of medical gases and strong and weak power supply. The same example of anesthesia tower, anesthesia machine use process generally need to use medical input gas (oxygen, air, laughing gas), medical output gas (anesthesia emissions), strong electricity (220V AC) and weak electricity (RJ45), in the past there is no tower, these supplies will be in the form of terminals or sockets are fixed in the operating room wall, now the application of the tower, will be on the wall of the wall of these supplies transferred to the Nowadays, the application of the hanging tower has transferred these supplies from the wall to the hanging tower, which facilitates the actual operation. So the relevant medical equipment mentioned here will be different from the relevant medical equipment mentioned in the first feature, because some equipment does not necessarily require these supplies.
