The invention discloses a medical infectious disease protection device, and relates to the field of medical instruments. The device comprises a head-mounted support, a front support and a rear support of the head-mounted support achieve multi-angle adjustment through a rotating mechanism, and a detachable soft support is arranged on the inner side of the head-mounted support; a vertical support of a hard frame of the eye protection assembly is rigidly connected to the lower side of a front side support, a transparent cover body is detachably installed on the hard frame in a magnetic attraction mode, and the cover body is provided with side protection wings bent backwards; according to the mask assembly, a soft frame is connected to the lower end of the vertical support through a ball head clamping piece, a U-shaped groove with a memory soft cushion is formed in the frame to seal the nose bridge, a protective film is fixed outside the soft frame, and the frame is tightly attached to the mouth and the nose through a pull rope with an adjuster. Eye protection and mouth and nose protection are integrated, comprehensive protection, dynamic sealing, pressure balance and convenient replacement are achieved through an adjustable mechanism and a self-adaptive sealing structure, and the wearing comfort and protection safety of medical staff are remarkably improved.

The application discloses a fuel cell visual testing device. The metal flow field plate and the cathode end plate are respectively provided with hollow channels, and the visual window body is encapsulated by a window protection sleeve and placed in a rectangular groove. The visual window body and the encapsulated end plate are both transparent bodies, and the combination forms a constant temperature chamber. Four end surfaces of the cathode end plate are symmetrically provided with constant temperature gas and reactant inlet and outlet ports. The metal foam is compressed in the conductive area of the metal flow field plate, and the uncompressed part forms a metal foam flow field by the combination of the metal flow field plate and is used as a visual fuel cell unit. The anode end plate, the anode current collector plate, the anode graphite plate, the membrane electrode assembly, the metal flow field plate, the cathode end plate and the encapsulated end plate are sequentially fastened and sealed. The device can effectively and accurately reflect the liquid water transmission and distribution in the flow field of the fuel cell. The hollow area of the metal flow field plate can be changed to different areas or different flow field shapes according to the testing requirements, so that the on-line visual testing of the fuel cell is realized.
