technical field

The utility model relates to the technical field of medical devices, in particular to a sputum suction device.

Background technique

Sputum suction is an auxiliary medical appliance in medical equipment. It is mainly used for routine suctioning and tracheotomy of the wounded and sick. For example, patients with respiratory diseases usually secrete more sputum and often need to use it. The sputum suction device sucks sputum for the patient.

FIG. 1 is a common sputum suction device at present, which mainly includes: a holding bottle 100 and a liquid storage bottle 200 placed in the holding bottle 100 . Among them, the liquid storage bottle 200 is a disposable product, and its material is relatively soft, and the storage bottle 100 is made of a rigid material and can be used repeatedly.

When in use, the liquid storage bottle 200 is placed in the holding bottle 100, wherein the holding bottle 100 is connected with a three-way pipe 110, the right end of the negative pressure pipe 300 is connected to the negative pressure machine 400, and the other end is connected to the three-way pipe 110. For connection, the other end of the three-way pipe 110 is connected to the cannula a through the connecting pipe 500 . One end of the suction connecting tube 600 is connected to the cannula b, and the other end is connected to the suction tube (not shown).

During the sputum suction operation, the negative pressure machine 400 makes the liquid storage bottle 200 in a negative pressure environment through the negative pressure tube 300 and the connecting tube 500, and then the sputum in the patient's body is removed through the suction connecting tube 600 and the connected sputum suction tube.
