The invention belongs to the technical field of operating room nursing, in particular to a waste collection nursing device for operating room nursing. Aiming at problems of failure in respective treatment of solid and liquid medical wastes, incompleteness in high-temperature treatment and high space occupation in solid waste storage, the provided scheme includes that the waste collection nursing device comprises a bottom box, a spring hinge is fixed to one side of the top outer wall of the bottom box through screws, a seal cover is fixed to the top outer wall of the spring hinge through screws, a fastener block is in butt fusion with the other side of the top outer wall of the bottom box, and a fastener is in butt fusion with the outer wall of one side, away from the spring hinge, of the seal cover. By a liquid storage bucket and a solid storage bucket, liquid treatment is realized through medical film applying, steam fumigating and high-temperature heating, and solid treatment is realized through ultraviolet sterilization, heating and drying and extrusion for block forming, so that solid and liquid are treated separately, high treatment efficiency is achieved, and germ residues caused by solid-liquid mixing are reduced. In addition, by a miniature push rod motor and a pressure plate, sterilized solid wastes can be compressed into blocks, and accordingly the problem of high space occupation in solid waste storage can be solved.
