The invention relates to the technical field of
medical instruments, and discloses a mounting mechanism and a
blood component separator, the mounting mechanism comprises a connecting piece, a hanging needle
assembly and a linkage
assembly. The connecting piece is provided with a first inclined surface, and an abutting part is arranged on the rear side of the first inclined surface; the linkage
assembly comprises a guiding piece and a follower, the follower is movably arranged between the guiding piece and the connecting piece, the follower is driven to move and has a first
stroke and a second
stroke, and when the linkage assembly is applied, the follower abuts against the first inclined face in the first
stroke and slides along the first inclined face so as to limit the front-back position of the connecting piece; when the follower moves backwards at the set position of the second stroke, the follower abuts against the abutting portion so as to drive the connecting piece to move backwards, and the hanging needle assembly moves backwards along with the connecting piece. The needle hanging assembly has various action requirements of keeping stable abutting, follow-up backward movement adjustment and forward movement return along with movement of the follower, it can be effectively ensured that the blood bag is always kept in a proper hanging state in the
separation process, and the problems caused by improper positions are avoided.
