Detailed Description
The VSD negative pressure drainage bottle of the present application is described in detail below with reference to the accompanying drawings.
The application discloses VSD negative pressure drainage bottle, it includes: lid 10, mother bottle 20, sub-bottle 30.
A first joint 11 and a second joint 12 are formed on the cover body 10, and the first joint 11 is used for connecting a drainage tube; the second joint 12 is used for connecting a negative pressure source through a pipeline; the cover 10 is formed with a circumferential side wall extending downward, and an inner surface of the side wall is formed with an internal thread.
The upper end of the mother bottle body 20 is opened, and the outer circumference of the upper end is formed with an external thread to be combined with the internal thread of the side wall of the cap body 10; a connecting pipe 22 is formed at the lower side of the bottom surface of the mother bottle body 20 and extends downwards; a valve body is formed in the middle of the connecting pipe 22 to control the connection and disconnection of the connecting pipe 22; a sub-bottle connection port 23 is formed at the lower end of the connection pipe 22, and an internal thread is formed on the inner circumference of the sub-bottle connection port 23.
