Description

technical field [0001] The invention relates to a surgical article, in particular to a portable headband for surgery and a helmet using the headband. Background technique [0002] Medical operators need to wear protective equipment during surgical operations, such as protective clothing, protective helmets, protective masks, etc., to protect the medical operator's body, head and face. Under normal circumstances, the helmet is used in conjunction with the mask and protective clothing to form a closed space inside the helmet.
