AI Technical Summary
Technical Problem
The existing connection between the nasobiliary duct and the drainage bag is loose and inconvenient to care for, while the existing fixation device has low convenience and low assembly and manufacturing efficiency.
Method used
A nasobiliary duct fixation device was designed, including a nasobiliary duct connector, a limiting soft plug, a fixing connector, and a limiting plug. The limiting plug deforms the limiting soft plug by squeezing it to increase friction. Combined with an interference fit and anti-slip protrusions, a stable connection between the nasobiliary duct and the drainage bag is achieved.
Benefits of technology
It effectively prevents nasobiliary slippage, improves the convenience of care, and simplifies the production and assembly process.
