Detailed Description

The utility model provides a separated AB pipe replacement pipe connector of a hemofilter, which comprises an end cover 5 and a fixed seat 3. The end cover 5 is detachably connected with the fixing seat 3, and both the end cover 5 and the fixing seat 3 can be made of non-metal materials.

The end cover 5 comprises a base 4, a connecting hole 9 is formed in the base 4, the connecting hole 9 is used for being connected with a fixing seat 3 which is described below, and a connecting head 12 of the fixing seat 3 is inserted into the connecting hole 9. The base 4 is also movably connected with a cover 1, wherein the movable connection is realized by a bolt, the cover 1 is a transparent cover, and the cover 1 can be made of plastic materials. When an AB liquid pipe needs to be inserted into the AB liquid seat, the cover 1 is in an open state; when the AB liquid tube is not inserted into the AB liquid holder, the cover 1 is in a closed state.
