Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure suction devices, in particular to a clinical negative pressure suction device. Background Art

[0002] As we all know, the negative pressure suction device is a medical device consisting of a negative pressure pump, a drainage tube, a connector, etc. It is usually mainly used for medical drainage, sputum removal, blood and secretions removal, etc. It uses the vacuum working principle to generate negative pressure in the cavity, thereby guiding the liquid and foreign matter in the cavity out to achieve the purpose of sewage purification. In oral surgery and treatment, the pipeline of the negative pressure suction device is usually placed in the oral cavity in an appropriate manner to discharge foreign matter and liquid.

[0003] However, during the suction process, traditional clinical negative pressure suction devices will mix foreign matter and liquid discharged from the oral cavity into the same container. This may cause the foreign matter to settle in the container or be mixed in the liquid, which is not conducive to subsequent processing and analysis. Therefore, technical improvements are urgently needed. Utility Model Content
