Description
Technical field
The utility model relates to testing equipment fields, and in particular to a kind of whole blood blood plasma automatic separating apparatus.
Background technique
Blood testing is biomedicine, clinical diagnosis, most commonly used pattern detection in health quarantine diagnosis, but red thin
There is very big interference to the spectrum analysis in blood testing in the presence of born of the same parents, therefore how quickly and easily to isolate from whole blood
Serum is always the hot spot and difficulties of blood testing research.
Overwhelming majority hospital and laboratory still use super-magnum centrifuge separation serum and haemocyte at present, and the method needs
The blood sample of milliliter amount is collected from patient's body, and really only several microlitres of sample for detection, lead to a large amount of of sample
Waste.And such centrifugation apparatus volume is big, complicated in mechanical structure, and serum separation process and detection are to be separated and independently performed, easily
Cause the loss and pollution of blood sample, be not suitable for the integrated of clinical diagnosis and micro-analysis system, at the same detecting step compared with
For complexity.
Utility model content
The technical problem to be solved by the utility model is to provide it is a kind of based on centrifugal force quickly by the blood plasma in whole blood from
Dynamic isolated whole blood blood plasma automatic separating apparatus.
The technical scheme adopted by the utility model is a kind of whole blood blood plasma automatic separating apparatus comprising rotating disk is set
Set disengagement chamber on the rotating pan and be connected respectively with disengagement chamber for convey whole blood into blood vessel and for conveying blood
Slurry goes out blood vessel.
Rotating disk described in the utility model is rounded, in being provided centrally with for rotating disc spins with driving for rotating disk
The centre bore that rotating mechanism is connected.
The other end described in the utility model into blood vessel is connected with whole blood chamber, the maximum of the whole blood chamber and axis of rotation
Distance is less than the minimum range of disengagement chamber and axis of rotation.
Disengagement chamber described in the utility model is divided into Erythrocyte preservation portion and blood plasma reservoir, and Erythrocyte preservation portion is located at blood
The outside of reservoir is starched, described to be connected into blood vessel with Erythrocyte preservation portion, the blood vessel out is connected with blood plasma reservoir.
The volumetric ratio of Erythrocyte preservation portion described in the utility model and blood plasma reservoir is 2:3.
Disengagement chamber described in the utility model is arranged radially along rotating disk.
The utility model it is described go out blood vessel on be provided with bending part, the rotation center of the bending part and rotating disk away from
From the minimum range for being less than disengagement chamber and rotation center.
The utility model is provided with adding hole on the whole blood chamber.
The good effect of the utility model are as follows: the utility model uses disc centrifuge structure, and whole blood carries out in disengagement chamber
Separation, since blood plasma is lighter, red blood cell is heavier, and rotating disk generates centrifugal force by rotation, under the influence of centrifugal force, heavier
Red blood cell is located at the outboard end of disengagement chamber, and lighter blood plasma is located at the inner end of disengagement chamber, then by going out blood vessel for blood plasma point
It carries out detection from next process is transported to or is mixed in other reagents, using simpler convenience, realize automatic point
From with conveying.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In the accompanying drawings, 1- rotating disk, 2- are into blood vessel, 3- whole blood chamber, 4- adding hole, 5- disengagement chamber, 501- Erythrocyte preservation
Portion, 502- blood plasma reservoir, 6- go out blood vessel, 7- center line, 8- bending part.
Specific embodiment
As shown in Fig. 1, the utility model include rotating disk 1, the disengagement chamber being arranged in rotating disk 15 and respectively with
Blood vessel 6, the rotating disk 1 out into blood vessel 2 and for conveying blood plasma for conveying whole blood that disengagement chamber 5 is connected are mounted on rotation
In mechanism, rotating disk 1 is driven to be rotated under the action of rotating mechanism, it is preferred that rotating disk 1 uses circle, rotating disk 1
The center of circle is that axle center is rotated.
The other end into blood vessel 2 is connected with whole blood chamber 3, there is the adding hole for whole blood to be added on whole blood chamber 3
4, the whole blood chamber 3 is less than the minimum range of disengagement chamber 5 and axis of rotation with the maximum distance of axis of rotation.Whole blood is added to
In whole blood chamber 3, under the action of rotating disk 1 rotates, whole blood is entered in disengagement chamber 5 into blood vessel 2, is centrifuged.Phase
For disengagement chamber 5, whole blood chamber 3 is closer apart from axis of rotation, and whole blood can be effectively ensured in this way can smoothly enter into disengagement chamber 5
It is interior.
Since blood plasma is lighter, red blood cell is heavier, under the influence of centrifugal force, Erythrocyte preservation portion is formed in disengagement chamber
501 and blood plasma reservoir 502, Erythrocyte preservation portion 501 is greater than in blood plasma reservoir 502 and rotation at a distance from rotation center
The distance of the heart.Since red blood cell accounts for about the 40% of whole blood, the volumetric ratio of Erythrocyte preservation portion and blood plasma reservoir is limited as 2:3, into
Blood vessel 2 is connected with Erythrocyte preservation portion, and the blood vessel 6 out is connected with blood plasma reservoir, can be effectively ensured from blood vessel 6 out
Discharge is blood plasma, will not adulterate red blood cell, guarantees accuracy in detection.
The disengagement chamber 5 passes through along the center line 7 that rotating disk 1 is arranged radially i.e. disengagement chamber 5 in the upright projection of rotating disk 1
The rotation center of rotating disk 1, helps to ensure that centrifugal effect.
It is provided with bending part 8 on the blood vessel 6 out, the bending part 8 is less than at a distance from the rotation center of rotating disk 1
The minimum range of disengagement chamber 5 and rotation center.Bending part 8 is closer apart from rotation center, and liquid needs bigger pressure just can be with
By the bending part 8 then into next process, whole blood residence time in disengagement chamber 5 can be extended, be sufficiently centrifuged
Separation, separating effect is very good, guarantees only have blood plasma that can just be discharged from blood vessel 6 out.
The utility model go out blood vessel 6 can connecting detection chamber, test chamber is similarly positioned in rotating disk 1, straight by going out blood vessel 6
Switch through shifting, avoid the loss and pollution of blood sample, is suitable for the detection methods such as scattering, transmission, fluorescence, chemical method.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by embodiment is stated to modify or equivalent replacement of some of the technical features；And these are repaired
Change or replaces, the spirit and scope for the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution.
