Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
In order to provide a kind of Medical tee joint connector for capableing of seal itself liquid pores, as shown in Figure 3 and Figure 4: Medical tee joint
Connector includes valve 6 and three connector branches 7 connecting with valve 6, and connector branch 7 includes shell 1, and shell 1 is interior along 1 axis of shell
To being provided with liquid pores 11；At least one connector branch 7 includes piston 2, spring 3 and gasket 4；Partition is provided in shell 1
12, liquid pores 11 are divided into exit orifice 111 and inner hole 112 by partition 12, are provided with limit convex at 111 aperture of exit orifice on shell 1
Edge 13 is provided with the intercommunicating pore 14 for being connected to exit orifice 111 with inner hole 112 in 1 side wall of shell；Piston 2 is located in exit orifice 111 and can
It is moved axially along exit orifice 111,2 surface of piston is provided with liquid groove 21；It connects, seals on the inside of gasket 4 and defining flange 13
There is the seal convexity 41 being adapted to liquid groove 21 on pad 4；Spring 3 is located between 111 bottom hole of piston 2 and exit orifice, and 3, spring
Support piston 2 makes piston 2 and 4 gluing, sealing of gasket, and seal convexity 41 seals liquid groove 21, and piston 2 is located at exit orifice 111 and connects
The outside of 14 junction of through-hole；When moving in piston, piston 2 can be located at the inside of exit orifice 111 and 14 junction of intercommunicating pore, or
