Inflatable protective equipment refers to a type of equipment that rapidly creates a sealed isolation space or forms an individual protective barrier through inflation. Its core principle involves using an air pump or high-pressure gas cylinder to inflate a structure made of specialized materials (such as airtight coated fabric, rubber, or composite film), causing it to expand and take shape, thereby achieving physical isolation from harmful substances, hazardous environments, or external contamination. Common types include inflatable negative-pressure isolation chambers for biological isolation and chemical contamination control, inflatable emergency disinfection tents, and some inflatable protective suits with airtight structures. These devices are characterized by rapid deployment, ease of transport and storage, and strong adaptability, and are mainly used in epidemic prevention and control, chemical accident emergency response, disaster relief, and temporary protection in special working environments.
