Description

Technical Field

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

[0002] Aspirators are used to remove bleeding, exudate, pus, and the contents of chest organs during surgery, ensuring a clear surgical procedure and reducing the risk of contamination. The principle behind aspirators is simple: by creating a negative pressure within the suction head, atmospheric pressure forces the material outside the suction head toward it, achieving the desired "suction" effect.

[0003] However, existing suction tubes are usually fixed, and the locations of bleeding, exudates, pus, and contents of chest organs during surgery are uncertain, which requires the suction device to be adjusted back and forth. However, the suction device is connected to the pipeline, and during the adjustment process, the impact on the pipeline or the impact of the pipeline on the adjustment must also be considered, making the operation very inconvenient.
