(1) can to make in the positive-pressure closing formula protective garment be 1～100mmH in the present invention
2The pressure of O, guarantee under the normal operating conditions gas by in the protective garment to outer discharging, except that normally the pumping into of Purge gas, the phenomenon that material is flowed in protective garment by the outside does not take place, the pollution of avoiding airborne pollutant that medical personnel are caused.
(2) the Purge gas amount that enters protective garment reaches 1～100 times of human body normal demand amount, with the timely discharge of the unimpeded and metabolism gas that ensures respiration.
(3) by portable, battery powered, the protection system operate as normal is more than 8 hours.
(4) the disposable use of protective garment, cost is low.
(5) enter the absorption of the interior gas of protection through filtration and active material, degree of purification reaches existing medical respiration level of protection.
(6) protection of the present invention can be applicable to the protection of serious infectious disease, the protection of the infectious diseases such as SARS that cause as SARS virus.
(7) the present invention also can be used for chemical defence and prevents the harm that fire initial stage smog causes human body except that being used for medical protection.
