Description
Technical field
The utility model relates to whole blood separation technology field more particularly to a kind of double arcs of full-automatic blood component separator
Face structure.
Background technique
Full-automatic blood component separator is used in the blood constituent preparation department of blood station more, and effect is will be in blood bag
Whole blood be separated into blood plasma and red cell suspension (mixed liquor of red blood cell and Precerving liquid).Before being initially separated operation, first will
Female bag equipped with whole blood, empty sub- bag and the Precerving liquid bag equipped with Precerving liquid hang or are placed on seperator, make female bag
In whole blood formed plasma layer in layered structure upper and that red blood cell layer is under.When being initially separated, squeezes female bag and squeeze plasma layer
Enter into sub- bag, then squeezes Precerving liquid bag, Precerving liquid is squeezed into female bag.
A stripper plate is equipped in existing seperator automatically to be squeezed female bag, but the shape of liquid bag is intermediate drum
The shuttle shape risen, and current stripper plate is planar structure, after being contacted with liquid bag in the middle part of liquid bag (plasma layer and red blood cell layer
Where interface) extruding it is more serious, the layered structure in liquid bag may be destroyed, lead to ingredient separation failure.
Therefore, it is necessary to provide a kind of extrusion structure for reducing whole blood layered structure in liquid bag and being destroyed risk.
Utility model content
The purpose of this utility model is to provide the extruding knots that whole blood layered structure in a kind of reduction liquid bag is destroyed risk
Structure.
To achieve the goals above, the utility model provides a kind of double cambered surface knots of full-automatic blood component separator
Structure, is set to full-automatic blood component separator, and the front end of the full-automatic blood component separator has the extruding for accommodating liquid bag
Section, is slidably equipped with a stripper plate in the extruding section, the thickness of the stripper plate middle section relatively thereon, down two
The thickness at end is smaller, makes the front end face and/or rear end face cambered surface of the stripper plate.
Compared with prior art, since the front end face/of stripper plate in the utility model or rear end face are cambered surface, shape with
The liquid bag of shuttle shape more matches, therefore entire liquid bag can be uniformly squeezed after contacting with liquid bag, will not cause to liquid bag middle part
Excessive compression, the risk that whole blood layered structure is destroyed in liquid bag when can effectively reduce extruding.
Preferably, being equipped with driving device in the body of the full-automatic blood component separator, the stripper plate lower end is solid
Surely there is connecting rod, the driving device drives the stripper plate to slide back and forth by the connecting rod.
Specifically, the driving device is motor, is additionally provided with sliding rack, screw rod and nut, the cunning in the body
Moving frame is set to slidingly back and forth in the body, and the nut is fixed with the sliding rack, and the screw rod is formed with the nut
The output shaft of nut-screw rod pair, the screw rod and the motor is fixed, and the connecting rod is fixed on the sliding rack.
More specifically, one end of two connecting rods is individually fixed in the sliding rack there are two the quantity of the connecting rod
Both ends, the other end of two connecting rods are individually fixed in the both ends of the stripper plate bottom.
Detailed description of the invention
Fig. 1 is the perspective view of the full-automatic blood component separator with the double globoidal structures of the utility model.
Fig. 2 is the side view of seperator in Fig. 1.
Fig. 3 is the schematic diagram hung up after liquid bag on seperator.
Fig. 4 is the structural schematic diagram of driving device and driving mechanism in seperator.
Specific embodiment
Description is made to the preferred embodiment of the utility model below with reference to the Figure of description provided.
As shown in Figure 1 and Figure 2, the utility model provides a kind of full-automatic blood component separator 1 and (hereinafter referred to as separates
Machine 1) double globoidal structures, uniformly to be squeezed liquid bag in seperator 1.The front end of seperator 1 is that band touches display
The front end 11 of screen 10, rear end are body 12, and front end 11 is spaced from each other with body 12, are formed accommodate squeezing for liquid bag between the two
13 between pressure area.The sub- bag that female bag and sky equipped with whole blood can be accommodated in the extruding section 13, specifically, in the front end of body 12
The rear end face of face and front end 11 is respectively equipped with the hook 15 of protrusion, and female bag and sub- bag are placed on hook 15.
Seperator 1 includes a stripper plate 16 being located in extruding section 13, and stripper plate 16 can be in extruding section 13 along preceding
The sliding of rear direction level.The thickness of 16 middle section of stripper plate relatively thereon, the thickness at lower both ends it is smaller, make stripper plate 16
Front end face and rear end face are cambered surface.
It is hung on the hook 15 of 12 front end face of body referring to Fig. 3, female bag a, sub- bag b is hung on 11 rear end face of front end
On hook 15, since the front/rear end of stripper plate 16 is cambered surface, can be located at the forward and backward sub- bag b of stripper plate 16, female bag
A matches fitting in shape.After stripper plate 16, which is slided backwards on, to be contacted with mother bag a, stripper plate 16 can carry out entire mother bag a
Uniformly squeeze；When 16 forward slip of stripper plate with sub- bag b to after contact, stripper plate 16 can uniformly squeeze entire sub- bag b.
In other embodiments, the front end face of stripper plate 16 only can be set as arcwall face and rear end face is plane, or only by rear end
Face is set as arcwall face and front end face is plane.
In conjunction with Fig. 4, driving device 17,16 lower end of stripper plate are equipped in the body 12 of full-automatic blood component separator 1
It is fixed with connecting rod 181, driving device 17 drives stripper plate 16 to slide back and forth by connecting rod 181.Specifically, driving device 17 is electricity
Machine, and extruding version is driven by a driving mechanism.In the present embodiment driving mechanism be the sliding rack 182 being located in body 12,
Screw rod 183 and nut 184, sliding rack 182 are set in body 12 slidingly back and forth, and nut 184 and sliding rack 182 are fixed, silk
Bar 183 and nut 184 form nut-screw rod pair, and screw rod 183 and the output shaft of motor are fixed, one end difference of two connecting rods 181
The both ends of sliding rack 182 are fixed on, the other end of two connecting rods 181 is individually fixed in the both ends of 16 bottom of stripper plate.When driving fills
After setting 17 startings, screw rod 183 drives nut 184 to be moved forward and backward, and fixed sliding rack 182 also slides back and forth with it with nut 184,
To drive stripper plate 16 to slide back and forth in extruding section 13 by connecting rod 181.In other embodiment, driving dress
It sets 17 and is also possible to the dynamical elements such as cylinder, and drive extruding by other driving mechanisms except 184 screw rod of nut, 183 pair
Plate 16.
Compared with prior art, since the front end face/of stripper plate 16 in the utility model or rear end face are cambered surface, shape
It is more matched with the liquid bag of shuttle shape, therefore can uniformly squeeze entire liquid bag after contacting with liquid bag, liquid bag middle part will not made
At excessive compression, the risk that whole blood layered structure is destroyed in liquid bag when can effectively reduce extruding.
Above disclosed is only the preferred embodiments of the utility model, and effect is to facilitate those skilled in the art
Understand and implement accordingly, the interest field of the utility model cannot be limited with this certainly, therefore special according to the present utility model application
