Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
Fig. 1 is the perspective view of the centrifugal blood component for centrifuge of the utility model embodiment one；Fig. 2 is that this is practical
The cross-sectional view of the horizontal vessel of the centrifugal blood component for centrifuge of new embodiment one.As depicted in figs. 1 and 2, blood
Being centrifuged component 10 mainly includes horizontal vessel 1, pipeline assembly 2 and exhaust valve 3.The horizontal vessel 1 can it is parallel (i.e. and chuck mode
The axis perpendicular of rotor) be installed on the chuck mode rotor of centrifuge, so as to the chuck mode rotor of centrifuge be able to drive it is sleeping
Formula container 1 is rotated around the central axes of chuck mode rotor.The shape of the horizontal vessel 1 be preferably rendered as it is rotational-like, preferably two
End is rendered into the cylindric of cone cell.The horizontal vessel 1 has the left centrifugal chamber 14 and right centrifugation being spaced apart along its axis direction
Chamber 15.The exhaust valve 3 is arranged on horizontal vessel 1 and is connected with left centrifugal chamber 14 and right centrifugal chamber 15, for left centrifugation to be discharged
Gas in chamber 14 and right centrifugal chamber 15 is each intracavitary to allow blood to enter.The pipeline assembly 2 includes the first flexible branch 21
With the second flexible branch 22 and flexible main line 23.Wherein, the first flexible branch 21 is identical with the structure of the second flexible branch 22, uses
To guarantee the fluid in pipeline assembly 2 (i.e. blood or blood after separation caused by product) in left centrifugal chamber 14 and right centrifugation
It synchronizes in chamber 15, equably flow.The one end on flexible main line 21 is flexible with the first end of the first flexible branch 21 and second simultaneously
The first end of branch 22 is connected, and the other end on flexible main line 21 is used to inject blood and extracts the production that blood generates after separation
Object, the second end of the first flexible branch 21 is connected with the left end 1a of horizontal vessel 1 and is connected to left centrifugal chamber 14, and the second flexibility is propped up
Road 22 is connected with the right end 1b of horizontal vessel 1 and is connected to right centrifugal chamber 15.
It is crouched first when in use according to the centrifugal blood component 10 for centrifuge of the utility model embodiment
Formula container 1 can be parallelly mounted on the chuck mode rotor of centrifuge, however the injector by being connected with its pipeline assembly 2
The left centrifugal chamber 14 of (such as injector for medical purpose) to horizontal vessel 1 is synchronous in right centrifugal chamber 15, is homogeneously added into blood, to blood
Liquid be added operation complete after restarts centrifuge, make horizontal vessel 1 under the action of centrifuge with chuck mode rotor together around
Its axis carries out high speed rotation, and left centrifugal chamber 14 and right centrifugal chamber 15 is enable to carry out independent separate to its internal blood, until blood
After each ingredient is completely segregated in liquid, in the case where not closing centrifuge, pass through the withdrawal device connecting with pipeline assembly 2
(such as injector for medical purpose) is layer-by-layer by the various composition (separated object i.e. in blood) in left centrifugal chamber 14 and right centrifugal chamber 15
It extracts, completes to turn off centrifuge after collecting.Compared with prior art, the centrifugal blood for centrifuge of the utility model
Component 10 is parallelly mounted on the chuck mode rotor of centrifuge using horizontal vessel 1, so that left centrifugal chamber 14 and right centrifugal chamber 15
It no longer rotates directed around own axes but is rotated around the axis of chuck mode rotor, guarantee that blood can be during the separation process
Bigger centrifugal force is generated, centrifugal blood component 10 is promoted to carry out more efficient separation to blood.
At the same time, the centrifugal blood component 10 for centrifuge of the utility model embodiment does not need operator at all
Have higher professional operation level can to blood after separation caused by various products be collected, and due to blood and
Its various product generated through separation can not substantially contact outside air during separation process and collection, so can
The risk of bacterium is introduced to be effectively reduced operator during collection.
Since the various composition content in blood is not identical, so the ingredient progress less to content is more smart for convenience
True collection can construct the centrifugal blood component 10 as follows, i.e., the radial dimension of the left end of left centrifugal chamber 14 along
The direction of right-to-left gradually becomes smaller, and the radial dimension of the right part of right centrifugal chamber 15 gradually becomes along direction from left to right
It is small, wherein horizontal vessel 1, left centrifugal chamber 14, right centrifugal chamber 15, the liquid entrance 14a of left centrifugal chamber 14 and right centrifugal chamber 15
Liquid entrance 15a it is coaxial.By lot of experiment validation, when the left end of left centrifugal chamber 14 and the right part of right centrifugal chamber 15
It is (13-14) that tapering, which is all presented: (32-33) it is coniform when, advantageously to the collection of the less ingredient of content in blood.By
The contour structures of the horizontal vessel 1 can also be influenced in left centrifugal chamber 14 and right centrifugal chamber 15, so working as a left side for left centrifugal chamber 14
Tapering is all presented is (13-14) to the right part of end and right centrifugal chamber 15: (32-33) it is coniform when, be also easy to favorably to its into
Row is more easily packed and is transported.
In the present embodiment, the horizontal vessel 1 include the left cup body 11 being connected with the first flexible branch 21 and with it is second soft
Property the connected right cup body 12 of branch 22, and connect left cup body 11 and right cup body 12 simultaneously and the centre of exhaust valve 3 can be installed
Even block 13.Wherein, left centrifugal chamber 14 is formed in left cup body 11 and centre connects between block 13, and right centrifugal chamber 15 is formed in right cup body
12 and centre connect between block 13.Left cup body 11 and the intermediate connection for connecting block 13 and right cup body 12 and the intermediate connection for connecting block 13
It hanks and is detachably connected or is fixedly connected, such as be bolted, welding, bonding or integrated molding etc..Preferably, left centrifugal chamber 14
Connect 13 mirror symmetry of block about centre with right centrifugal chamber 15, so that left centrifugal chamber 14 can be to the blood of equivalent with right centrifugal chamber 15
Separation is synchronized, the two is synchronized, the various products that equably output blood generates after separation outward, to avoid
One of the case where waiting another, occurs.
In this embodiment, horizontal vessel 1 includes set on the left elbow 16 between the first flexible branch 21 and left cup body 11
