The invention relates to a negative pressure suction device for sputum suction, which belongs to the technical field of medical instruments and comprises a mounting frame, a negative pressure mechanism and a sputum collector. The sputum collector comprises a negative pressure bottle placed on the mounting frame, an opening is reserved in the upper side of the negative pressure bottle, and a sealing cover is connected to the opening in a sealed mode; a disposable sputum collecting bottle is arranged on the inner side of the negative pressure bottle, and a positioning assembly for fixing the disposable sputum collecting bottle is arranged on the side, close to the negative pressure bottle, of the sealing cover. The sealing cover is provided with a first communicating hole and a second communicating hole, and further comprises a disposable sputum suction tube and a negative pressure connecting tube; one end of the disposable sputum suction tube penetrates through the first communication hole and is arranged in the disposable sputum collection bottle; the negative pressure connecting pipe penetrates through the second communicating hole and is arranged on the outer side of the disposable sputum collecting bottle; and fixing assemblies are respectively arranged at the first communicating hole and the second communicating hole. The disposable sputum collection bottle and the disposable sputum suction pipe can be replaced and treated rapidly, and the cleaning work coefficient is reduced.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a negative pressure suction device for suctioning sputum. Background technique [0002] At present, negative pressure suction equipment is widely used in clinical work. It uses the working principle of vacuum to generate negative pressure in the cavity, so as to guide the liquid in the cavity to achieve the purpose of sewage purification. [0003] The negative pressure suction equipment in the prior art generally includes a negative pressure mechanism, a sputum collection bottle connected with the negative pressure mechanism, and a sputum suction tube. When in use, when the negative pressure mechanism generates negative pressure, sputum is sucked through the sputum suction tube. [0004] Although this method can perform sputum suction operation, in the prior art, the general sputum suction tube is a disposable tube, and when the inner sputum collection bottl...
