The nursing pollutant collecting device comprises a box body, wherein a throwing hole is formed in the middle of the top surface of thebox body; three vertical tubes are uniformly arranged on the lower portion of the inner end of the throwing hole; the vertical tubes are made from transparent plastic materials and are distributed upand down; a transverse partition plate is arranged between gaps of adjacent two vertical tubes; the top surface and the bottom surface of the partition plate are in contact with and matched with the end surface of the corresponding vertical tube, separately; the three vertical tubes are fixedly connected to the inner part of the box body through a first bracket; a first through hole is formed in the upper side of the right end surface of the box body; a first transverse rod is arranged in the first through hole; the inner end of the first transverse rod is fixedly connected to the right end ofthe partition plate on the upper portion; a round leaking hole is formed in a position, close to the left end, of the upper portion of the partition plate; the leaking hole can communicate with the vertical tube; and transverse hydraulic telescopic rods are arranged at the left and right ends of the partition plate on the lower portion. The nursing pollutant collecting device can be helpful for medical staff to finish ultraviolet disinfection of nursing pollutants quickly, and the staff can be fully prevented from being in contact with the pollutants when the pollutants are bagged and tied bythe nursing pollutant collecting device.

The invention relates to the technical field of aluminum material processing, in particular to a preparation method for an aluminum material painted by vegetable dyes. The preparation method comprisesthe following steps that (1) a mold plate is manufactured; (2) the vegetable dyes are prepared; (3) mold plate filling is conducted; (4) impression is conducted; (5) high-temperature volatilization is performed; (6) bletilla striata liquid is sprayed onto the aluminum material; and (7) vacuum drying is conducted. A pattern is drawn on the obtained aluminum material and filled with various colors,and the dyes with the multiple colors are all made from natural plants and are free of poisonous substances and pungent odor and suitable for indoor application; through impression, volatilization and bletilla striata liquid coating, the color curing degree is high, natural disengagement is generally avoided under the non-friction condition, and the service life of the pattern of the invention islonger compared with the service life of a pattern obtained in the mode that a worker directly uses a paintbrush for direct painting with vegetable dyes.
