Closed end 222 and lateral perforate of neighbouring closed end 222 224 be exposed to outside the first sealing 231.And by pillar 225, even
Socket part 22 can more easily penetrate the first elastic mouth 2310.
It is moveable by interconnecting piece 22 in this present embodiment, and is pushed away simultaneously by the second feather valve 23 and third feather valve 24
It supports, when the pushing and pressing of first sleeve 11 are when the second feather valve 23, the pushing and pressing of the second feather valve 23 are in interconnecting piece 22, and interconnecting piece 22 pushes against
In third feather valve 24, therefore 24 deflection deformation of third feather valve, and interconnecting piece 22 is mobile towards medicine bottle B.Specifically, interconnecting piece
22 are moved to the open end 221 of interconnecting piece 22 through the second elastic mouth 2410, are thus connected to second channel 211 and third channel
223。
On the other hand, when the first connection component 10 is connect with the second connection component 20, the interconnecting piece 22 of exposing can be across
First opening 1110 and protrude into the first passage 111 of first sleeve 11, push against in the first feather valve 12, therefore make the first feather valve
12 deflection deformations and open the first opening 1110.Specifically, being with pillar 225 when interconnecting piece 22 protrudes into first passage 111
It pushes against in the first feather valve 12, and then deforms the first feather valve 12 and open the first opening 1110.For example, in fact such as aforementioned first
Apply in example, the embolism column 122 of the first feather valve 12 can deflection deformation due to interconnecting piece 22 pushes against, even if the disk of the first feather valve 12
Body portion 121 keeps still openable first opening 1110 in situ；Or in such as aforementioned fourth embodiment, the deflection division of the first feather valve 12
124 can deform because interconnecting piece 22 pushes against embolism column 122, cause embolism column 122 mobile towards the direction syringe A, open first and open
Mouth 1110.When the first opening 1110 is opened, so that first passage 111 and third channel 223 are interconnected.
So far, first passage 111, second channel 211 and third channel 223 are interconnected, therefore the medical fluid in medicine bottle B
Can sequentially via medicine bottle B, second channel 211, third channel 223, first passage 111 and flow in syringe A.
After completing infusion, during again separating the first connection component 10 with the second connection component 20, first is logical
The side wall in road 111 can slowly remove second channel 211, and the first sealing 231 of the second feather valve 23 can be towards the first connection group
The direction of part 10 is mobile and is persistently resisted against around the first of first passage 111 the opening 1110, while interconnecting piece 22 is held in the
In the elastic mouth 2310 of the first of one sealing 231, thus during separating between first passage 111 and second channel 223 between
Away from not will increase.
When the first connection component 10 is further separated with the second connection component 20, the first sealing 231 continues towards first
The direction of connection component 10 is mobile, and covers the lateral openings 224 of interconnecting piece 22, therefore completely cut off first passage 111 and third
Channel 223.Then, the first sealing 231 is coated on pillar 225, so that pillar 225 is no longer abut against on embolism column 122.At this time
Interconnecting piece 22 is covered by the first sealing 231 completely, and the first elastic mouth 2310 is closed completely；And the first feather valve 12 no longer by
Power and restore, therefore the first opening 1110 can be sealed.
Then, second channel 211 is persistently removed with the side wall of first passage 111, the first sealing 231 also continues towards second
Opening 2110 is mobile.When the side wall of first passage 111 is fully removed second channel 211, the first sealing 231 is also moved to second
Opening 2110, and seal the second opening 2110；The first connection component 10 is kept completely separate again with the second connection component 20 at this time.Cause
This, the medical fluid remained in first sleeve 11 will not there will not be liquor residue in first sleeve by 1110 outflow of the first opening
Outside 11.Meanwhile the both ends of second channel 211 have been obstructed after the reinstatement of third feather valve 24, to increase by the second connection component 20
Internal closure prevents medical fluid from flowing into second sleeve 21 by medicine bottle B again.
Therefore, during the first connection component 10 is separated with the second connection component 20, the first sealing 231 can first cover
The lateral perforation 224 of lid, therefore medical fluid will not be again by 224 inflow first passages 111 of laterally perforating.Then the first sealing 231 wraps
It covers pillar 225 and pillar 225 is separated with the first feather valve 12, so that the first opening 1110 of the first feather valve 12 sealing, therefore medicine
Liquid will not be back to the second connection component 20 by the first opening 1110 again.And during continuing separation, the first sealing 231
It is persistently resisted against the side wall of first passage 111, therefore not will form gap between the first sealing 231 and the first opening 1110 and hold
Receive medical fluid.As a result, after the first connection component 10 and the second connection component 20 are kept completely separate, the first sealing 231 seals the
At two openings 2110, making just will not residual liquor at the first opening 1110 and the second opening 2110.
Next referring to Figure 12 and Figure 13.The present invention is other than it can be used to connect syringe and medicine bottle, it may also be used for connection
Infusion bag C1 and human body.Specifically, the both ends of a perfusion tube C2 are respectively communicated in infusion bag C1 and the first connection component 10, because
This enables infusion bag C1 to be connected to the first connection component 10.Similarly, one end of a human body end conduit D is equipped with syringe needle and (schemes not
It is painted), the other end is connected to the second connection component 20.Perfusion tube C2 can directly be connected to infusion bag C1 and the first connection component 10
(as shown in figure 12) intermediate can also be serially connected with a shunt head C3 (as shown in figure 13) can input two kinds of medical fluids simultaneously.In addition, such as
