Surgical helmet

摘要

A surgical helmet assembly (10) including a ventilation system for circulating air around the head of a user. The surgical helmet assembly includes a surgical helmet (12) including a brow bar (22) to be positioned around the head of the user and a chin bar (20) extending from the surgical helmet to be positioned in front of the chin of the user. The chin bar and brow bar include an airflow channel (82) in fluid communication with a fan (32) at the rear of the surgical helmet. The fan generates a flow of air from an airflow inlet at the rear of the surgical helmet through the airflow channel in the chin bar to an airflow outlet (60) in the chin bar and past a user's face in an upward direction and through the airflow channel in the brow bar to an airflow outlet (64) in the brow bar and upward over the user's head.
