Zusammenfassung: | The utility model discloses a sputum collecting device which comprises a sputum storage with a sputum storing cavity. An opening is formed in the sputum storage. A cover body is arranged at the opening in a covering mode. A sputum sucking pipe and a negative pressure pipe communicated with the sputum storing cavity are connected to the cover body in an inserting mode. The negative pressure pipe comprises a head pipe opening part which is inserted into the sputum storing cavity and a tail pipe opening part corresponding to the head pipe opening part. A negative pressure device with a column-shaped cavity is included. A first opening and a second opening are formed in the negative pressure device. A piston arranged in the column-shaped cavity is included. The piston and the inner wall of the column-shaped cavity are matched in a sealing mode, and the piston is placed between the first opening and the second opening. A negative air cylinder is included. A piston rod of the negative air cylinder is fixedly connected with the piston. A PLC control unit is included. The PLC control unit is used for controlling the moving stroke of the piston rod on the negative pressure air cylinder. The tail pipe opening part of the negative pressure pipe is communicated with the column-shaped cavity through the second opening. Electronic controlling and judging accuracy is high, compared with manual operation, accuracy is high, the device is suitable for operation by green hands, for a veteran, working intensity can also be lowered, and unnecessary manpower loss is avoided. |
