The bearing arm is a structure whose arm is rotatable, of adjustable height and extendible and which can, for example, be clamped to a bed and is used to support, for example, artificial respiration hoses for a patient who requires artificial respiration. The advantage of this structure over existing bearing arms is that in this case there is no possibility of the hinge sinking, as is the case in other structures. The special structure of the fixing device means that it exerts an increasingly strong pull when subjected to load yet can nevertheless be detached by exerting a slight pressure on the right- angled strip. |
