Abstract

<P>PROBLEM TO BE SOLVED: To provide a mask used for transporting a patient with an infectious disease with which the patient with the infectious disease is rapidly transported to a medical institution while securing safety of transportation staffs, even when a large number of patients with the infectious disease are present. <P>SOLUTION: The mask main body 2 of a mask 1 used for transporting the patient with the infectious disease is put on to cover the whole head of a patient A with the infectious disease (including a patient suspect who may have the infectious disease). The lower part 2a of the mask having a rubber material (unillustrated) is brought into tight contact with the circumference of the neck of the patient A with the infectious disease for sealing by fixing with a belt member 4. An air supply/discharge device 6 connected to the mask main body 2 via a tube 7 discharges contaminated and removed air. Then the patient is transported in a state where the mask main body 2 is in the negative pressure state. <P>COPYRIGHT: (C)2005,JPO&NCIPI
