Description

Technical Field

[0001] The present invention relates to the technical field of hepatobiliary surgical nursing, and in particular to a hepatobiliary nursing drainage device with an anti-blocking structure. Background Art

[0002] Hepatobiliary surgery mainly studies major diseases that seriously threaten the health of the Chinese people, such as hepatocellular carcinoma, hepatobiliary stones, post-hepatitis cirrhosis and acute liver failure caused by severe hepatitis. After the completion of hepatobiliary surgery, drainage is a relatively important task. Drainage refers to the act, process and method of extracting fluid from a body cavity or wound by suction or gravity.

[0003] However, when some existing drainage devices for hepatobiliary care are in use, the pipelines are easily blocked due to bile viscosity, tissue fragment deposition, catheter distortion, etc., resulting in poor drainage. In addition, during clinical use, the drainage devices may also encounter blood clots blocking the drainage tubes. This generally requires nurses to manually squeeze the drainage tubes to squeeze out the blood clots in order to maintain smooth drainage. However, manual squeezing of the drainage tubes may cause damage to the drainage tubes and even cause discomfort to the drainage patients. It is less practical and cannot effectively prevent blockage. In view of this, we propose a hepatobiliary care drainage device with an anti-blockage structure to solve the above problems.
