The invention relates to a negative pressure square cabin clinical check module. The negative pressure square cabin clinical check module includes a clinical check unit, a disinfection and sterilization unit, and an operation unit; the same sides of the clinical check unit and the operation unit are correspondingly connected with medical channel units through channel devices, and the other sides of the clinical check unit and the operation unit are correspondingly connected with patient channel units through the channel devices; the other sides of the patient channel units are connected with the disinfection and sterilization unit through the channel devices, and the lateral parts of the clinical check unit, the disinfection and sterilization unit, and the operation unit are respectively connected with negative pressure cabin bodies; air supply and
filtration efficiency of the negative pressure cabin bodies is greater than or equal to 99.9% @ 0.3 [mu]m, and air exhaust and filtering efficiency of the negative pressure cabin bodies is greater than or equal to 99.9% @ 0.3 [mu]m to 0.5 [mu]m; and the negative pressure cabin bodies enable the formation of the negative
pressure difference not less than 20 Pa between outer side environment and the clinical check unit, the disinfection and sterilization unit, and the operation unit, and the negative pressure cabin bodies enable the formation of negative
pressure difference not less than 10 Pa between the outer side environment and the medical channel units, the patient channel units, the channel devices. According to the negativepressure square cabin clinical check module, main clinical check and analysis in the treatment of infectious diseases can be realized, the negative
pressure function is brought, the channel devices have the telescopic function, and effective check and treatment places can be provided for natural disasters, local wars, infectious
disease prevention and control, and the like.
