Abstract

A sputum collecting device comprises a first cavity (1) used for storing sputum and a cover body (2) matching the first cavity (1). One end of the first cavity (1) is of an opening structure, and the other end of the first cavity (1) is of a sealed structure made of an elastic material. The side wall of the first cavity (1) extends axially from the sealed end of the first cavity to form a supporting base (3) of the first cavity. The supporting base (3) is provided with a clamping groove (4) used for being connected to a vibration mixer. The cover body (2) can be closed at the opening structure end of the first cavity. The cover body is provided with a sputum smearing nozzle (5), a second cavity (6) used for storing a sputum liquefier, and a center structure (7). The sputum smearing nozzle (5) is in communication with the first cavity (1) through an internal channel of the sputum smearing nozzle (5). One end of the second cavity is of an opening structure, and the other end of the second cavity is of a supporting structure (13). Liquefier capsules (8) containing the sputum liquefier are disposed in the second cavity. The supporting structure end of the second cavity is used for preventing the liquefier capsules from entering the first cavity (1). Pores (14) for allowing the second cavity (6) to be in communication with the first cavity (1) are formed in the supporting structure end of the second cavity (6). The center structure (7) is used for puncturing the liquefier capsules (8) in the second cavity to allow the sputum liquefier to flow into the first cavity.
