Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model provides a negative pressure formula bile blake bottle for it cultivates to stay to get the bile, as shown in fig. 2, it includes bottle body 7, and bottle body 7 is the tubbiness structure, and the one end of tubbiness structure is the open end, and the other end is the blind end. The open end of the bottle body 7 is in threaded matching connection with the second cap 6, and the closed end of the bottle body 7 is in threaded matching connection with the first cap 8. The second lid 6 is the same size as the first lid 8.

The outside of the open end of bottle body 7 and blind end all is equipped with the external screw thread, and the inboard of second lid 6 and first lid 8 all is equipped with the internal thread, and the external screw thread on the bottle body 7 all matches with the internal thread of second lid 6 and first lid 8.

The second cover 6 is provided with a first connecting pipe 1 and a second connecting pipe 5 in a penetrating way, and the first connecting pipe 1 and the second connecting pipe 5 are fixed on the second cover 6. One end of the first connecting pipe 1, which is positioned at the outer side of the second cover 6, is used for being connected with a T pipe (namely a bile drainage pipe), and a clamp 2 for opening and closing the passage of the first connecting pipe 1 is arranged at the outer side of the second cover 6 on the first connecting pipe 1; one end of the second connection pipe 5 located outside the second cover 6 is connected to and communicated with one end of the air release bag 4. The other end of the exhaust bag 4 is provided with an exhaust valve 3, and the exhaust valve 3 is a one-way valve, namely, the gas in the exhaust bag 4 can be discharged from the exhaust valve 3, but the gas outside the exhaust valve 3 (namely, the external gas) can not enter the exhaust bag 4.
