Including two sections: first segment and second segment, wherein first segment is round table-like, this section is provided with cone spring that shape is mutually agreed with as bullet
Property preload piece 6, second segment be it is cylindric, first segment and second segment junction are provided with sealing ring 10, and such setting acts on
Positioning when, first segment is mainly used for grafting and arrange elastic preload piece 6, and second segment is for substantive sealing, such as
This facilitates grafting to position, and also improves sealability, realizes and take into account.
In further embodiment provided by the invention, optionally, interconnecting piece 2.1, the company are additionally provided in the main body 2
Socket part 2.1 is secured in fixed reference by screw bolt and nut, and fixed reference refers to fixation when hemoperfusion apparatus operation
Basis, common frame body or cabinet body when such as blood perfusion, hemoperfusion apparatus provided in this embodiment is preferably integrated into whole
On the immobilizing foundation of a operation, interconnecting piece 2.1 can be through-hole, spiro union portion or clamping portion, so be fixed to main body 2 corresponding
Fixed reference on.
In further embodiment provided by the invention, further, block 9, the company are slidably connected in the main body 2
Connecting road 3 is the pipeline 11 that the through hole being opened on the block 9 namely interface channel 3 are not separately provided, but is opened up
Through hole in a 9 shape structure of block, for block 9 convenient for driving, a hand grip device is arranged thereon can be realized hand
Dynamic driving.
In the present embodiment, it is preferred that sliding rail 7 is provided in main body 2, the basal sliding of block 9 is connected in the sliding rail 7,
So realize the limit of 9 motion profile of block, further, as shown in figure 5, the inside setting of sliding rail 7 is fluted, block 9
Bottom is provided with protrusion, and protrusion, which is slidably connected in the groove, to be realized and be slidably connected and realize limit, further, protrusion and
Groove all has certain preset clearance on horizontal position and depth position (horizontal direction and vertical direction in Fig. 5), this
In the reason of preset clearance is set be to reserve nargin for the grafting of connection-peg 1.2 and interface channel 3, if cooperating simultaneously round table-like
Connection-peg 1.2 and interface channel 3 so that there is biggish alignment range when the two grafting.
As another optional scheme, elastomer such as elastic cushion is set in protrusion or groove, so in the movement of block 9 and
In use process, protrusion and groove can squeeze elastic cushion, so can equally provide certain activity nargin, and provide preload
Power.
In further embodiment provided by the invention, further, locking member 5 is passive type locking mechanism, here passively
Formula refers to that its locking process is passive triggering, without active operation, so closes above-mentioned grafting, movement, three steps of locking
And be grafting and mobile two steps, i.e. the end of moving process realizes locking automatically.
The passive type locking mechanism of the present embodiment can be there are many implementation, and one is aptitude manner, such as setting one
Sensor detects the position of block 9, and when detecting it and reaching link position, automatic driving locking member 5 realizes locking.
Secondly, it is preferred that locking member 5 is electromagnetic locking structure, and electricity is respectively set in locked position on block 9 and main body 2
Two parts of magnetic suck structure are provided with impact structure on block 9, when block 9 moves to grafting end of travel, impact structure
The switch of electromagnetic structure is hit, electromagnetic adsorption structural priming on block 9 magnetic to main body 2, realizes that position maintains, namely realize
The power supply cut-off push button of a cut-off push button such as electromagnetic adsorption structure, blood perfusion dress is separately provided in locking, electromagnetic adsorption structure
It sets when unlocking, starts cut-off push button, electromagnetic adsorption structure disconnects, namely starts locking member 5 automatically by the movement of block 9.
Third, most preferred, the locking member 5 includes unidirectional auxiliary member 5.1, and one end of the actuator 4 passes through rotation
Part 5.2 is rotationally connected in the main body 2；The unidirectional auxiliary member 5.1 is movably set in the main body 2, when described unidirectional
