Specific embodiment
In order to more fully understand the technology contents of the utility model, below in conjunction with attached drawing and specific embodiment to this
Utility model is described further and illustrates.
Embodiment 1
As shown in Figure 1, a kind of detachable fixed device of blood taking bag centrifugation shown in the present embodiment, including upper end is opening
Box body 1, the surrounding side-wall outer side of box body 1 is equipped with telescopic rod 2, two pieces of fixed plates disposed in parallel is movably equipped in box body 1
3, the back side (i.e. the other sides of two fixed plates opposite sides) of two fixed plates 3 is equipped with connecting rod 31, the company in two fixed plates 3
The free-end of bar 31 is pierced by the front-rear side walls of box body 1 respectively, and 31 end of connecting rod for being placed in 1 outside of box body is equipped with handle 32,
Spring 33 is arranged on connecting rod 31, spring 33 is placed between 1 side wall of fixed plate 3 and box body, makes to constitute bullet between two fixed plates
Property is to pull-up structure；In above structure, the device can be made to be detachably secured in centrifuge by the telescopic rod of box body surrounding
In rotor, handle is then stretched out, expands the distance between two fixed plates (gap) to be put into the blood taking bag that need to be clamped,
After blood taking bag is put into, unclamp handle, using the elastic force of spring make two fixed plates move toward one another reduce between the two distance (
Gap) until clamping blood taking bag；The device overall structure is simple, dismantles and is fixed conveniently, and is applicable to the blood sampling of plurality of specifications
Bag, not only increases centrifugal efficiency, could be applicable to most of centrifuges, for example, Thermo company centrifuge (model:
ST16/ST40), Eppendorf company centrifuge (model: 5418), the centrifuge of Kubota company (model: 8420) etc..
Specifically, length direction setting and with the front-rear side walls of box body 1 parallel, the left side of box body 1 of the fixed plate 3 along box body 1
Right side wall is vertical with fixed plate 3, and the gap length between such fixed plate can simultaneously clamp on multiple blood taking bags；1 left and right sides of box body
About two parallel guide rails 11 are equipped on the inner wall of wall, and two guide rails in 1 left and right sidewall of box body correspond respectively
And it is in same level, 3 left and right ends of fixed plate are equipped with the notch 34 that cooperation is corresponded with guide rail 11 up and down, make to fix
Plate 3 does longitudinal movement in the width range of box body 1 along guide rail, prevents fixed plate from occurring using the cooperation of guide rail and notch circumferential
Deflection, avoids the problem of causing clamped condition to loosen after fixed plate deflects, and begins after so that two fixed plates is clamped article
The state effectively clamped is kept eventually.
Specifically, 3 back side of two fixed plates is equipped at intervals with two parallel connecting rods 31, and two connecting rods 31 are divided into admittedly
The left and right sides of fixed board, the free-end of two connecting rods 31 pass through the through-hole (not shown) being set on 1 side wall of box body, through-hole
The micro- diameter greater than connecting rod of diameter, facilitate connecting rod to move back and forth in through-hole；Handle 32 is fixed on the end of two connecting rods 31,
Two connecting rods are pulled simultaneously by handle, makes fixed plate or so uniform force and carries out integral translation, prevent fixed plate or so
Discontinuity causes fixed plate that longitudinal deflection occurs, and can ensure that the clamping force between two fixed plates is balance, makes two to consolidate
The state effectively clamped is remained after fixed board clamping article.
Embodiment 2
As depicted in figs. 1 and 2, a kind of detachable fixed device of blood taking bag centrifugation shown in the present embodiment, in embodiment 1
On the basis of the structure, the opposite surface of two fixed plates 31 is stained with non-slip mat 35, and fixed plate and clamping article can be improved
Frictional force between (i.e. blood taking bag) further prevents blood taking bag to move in centrifuge centrifugal process.
Embodiment 3
As shown in Figures 1 to 4, a kind of detachable fixed device of blood taking bag centrifugation shown in the present embodiment, in embodiment 2
On the basis of the structure, it is equipped with telescopic rod 2 in the two corners of each side-wall outer side upper end in box body 1, can guarantee box body in this way
Power suffered by surrounding is balance when being fixed on centrifuge, has ensured stability and reliability after box body is fixed.
Specifically, telescopic rod 2 includes that one end is fixed on the hollow stem 21 of box body and scalable is sheathed in hollow stem 21
Motion bar 22, the outer sheath in hollow stem 21 and motion bar junction is equipped with retaining ring 23, and sky is fixed in 23 one end of retaining ring
On the outside of core bar, the other end is set on the outside of motion bar and between motion bar there are gap, and portable propelling bar is stretched and shunk, set
The screw 24 for holding out against motion bar is equipped with loaded on retaining ring one end on the outside of motion bar；When stretch bar consolidates Snap of box
It after centrifuge, then is held out against by tightening screw for motion bar locked, to fix the length of telescopic rod, prevents telescopic rod
Length in centrifugal process the influence of stress change whole device caused to loosen.
Specifically, the free-end end (i.e. the free-end end of motion bar) of telescopic rod 2 is equipped with rubber pad 25, can mention
Frictional force between high telescopic rod and centrifuge inner wall further prevents whole device to move in centrifuge centrifugal process
Or the phenomenon that loosening.
