Abstract
The utility model relates to a kind of anti-clogging double-cavity suction tubes, including the suction tube main body with connector, connector is used to connect with negative pressure source;Suction tube main body includes main pipeline and branch pipeline, main pipeline and branch pipeline are communicated with connector, pipeline switching structure is set on main pipeline and / or branch pipeline, pipeline switching structure is used to open and close according to the pressure variation of main pipeline Branch pipeline.This utility model can open branch pipeline in time when main pipeline is blocked, continue to carry out suction operation, avoid suction tube from being blocked and unable to work normally;Without interrupting operation to dredge or replace suction tube in operation due to suction tube being blocked, reduce operation time, reduce patient anesthesia risk, avoid repeatedly operating to destroy sterile environment simultaneously, reduce infection risk, improve operation accuracy.
