True sample mounting device.
To achieve the above object, the utility model provides the following technical solutions：A kind of artificial blood vessel's vivo environment simulation survey
The realistic testing specimen mounting device of examination, structure are：Firm banking is equipped with sliding slot, and two-way collet and threeway collet are solid respectively
Due in a pair of brackets, support vertical is nested in sliding slot；The both ends of two-way collet and threeway collet screw up connection respectively
Connector, connector are equipped with liquid entrance, and the both ends of seal pipe connect with the connector of two-way collet and threeway collet respectively
It connects；Water inlet is provided in seal pipe, sealing cover closes water inlet；Ultra-thin elastic silicone tube is placed in seal pipe, it
Both ends are socketed on respectively at the liquid entrance for the connector being connect with two-way collet and threeway collet.
Compared with prior art, the realistic testing specimen installation of artificial blood vessel's vivo environment simulation test provided by the utility model
The advantageous effect of device is：Due to increasing the leakproofness of device, make sample mounting device by opening into sealing；Reduce sample
Installation space keeps sample installation compacter, greatly reduces the volume of simulated body fluid；It can live between firm banking and holder
It is more flexible that the connection of dynamic property makes the testing length of artificial blood vessel's sample adjust.
