Technical Field

The utility model relates to a bile suction device field, specifically say, relate to a bile suction device is used in hepatobiliary surgery ERCP operation.

Background

Currently, many patients with poor drainage after ERCP surgery require the use of a complex aspirator to aspirate bile by external suction. The interface of ERCP is not matched with negative pressure suction interface in clinic, and at present, glass joints are generally adopted to connect two ends. But glass joint can appear leaking gas phenomenon after cup jointing with the interface, leads to the bile to ooze, because leaks gas, the negative pressure in the connecting tube can disappear, needs the nurse to extrude repeatedly and forms artificial negative pressure, has so both increased work load, also makes the drainage effect unsatisfactory. On the other hand, sometimes the glass fitting is too tightly engaged with the ERCP interface and the catheter cannot be easily removed, or even the glass fitting is broken into the ERCP interface, making the entire ERCP unusable. This increases the workload of nurses and the risk of adverse flow infection of patients, and therefore it is highly desirable to fabricate a bile aspiration device for the ERCP surgery in hepatobiliary surgery.
