Description

technical field [0001] The invention relates to the technical field of safety appliances, in particular to a safety belt assembly and a lumbar traction bed including the same. Background technique [0002] At present, most of the lumbar traction beds used in medical institutions adopt the form of leg triangular pads and waist straps to fix patients, so as to achieve lumbar traction treatment. The above fixed form has the following disadvantages: [0003] 1. It needs medical staff to help wear and disassemble, which is inconvenient to use; [0004] 2. The tightness of the strap needs to be confirmed with the patient several times. Too loose will easily cause the patient to slip during traction, and too tight will hinder the patient's blood circulation; [0005] 3. During the traction process, the straps are kept tight all the time, and patients tend to feel uncomfortable; [0006] 4. During the traction process, if the patient adjusts the body position or changes the movem...
