Description
Technical field
The present invention relates to medical experiment equipment, specifically cross matching and ABO and RhD blood groups and irregular antibody examination adds
Sample device.
Background technology
Up to the present, situation of all-level hospitals Blood Transfusion Dept. to be that blood transfusion cross match blood test, ABO be positive and negative and RhD bracket for blood grouping with
And in serum during three big experiment of irregular antibody examination be loaded using common plasticses suction pipe or plastic dropper, if by
Blood person needs donor bloods more than two person-portions, and extremely complex, every blood donor is tested in its cross matching done before transfusing blood
Cross matching experiment will be carried out between receptor and between every blood donor and blood donor, such as experiment of y-bend one needs six
Branch transparent pipe, each transparent pipe sample-adding blood cell and serum once, need to be respectively loaded 12 times, the experiment of trident one needs sample-adding 24 times altogether,
And blood cell and serum push the wrong bit pairing mode be added to supervisor and time pipe, it is seen that only be loaded process it is just very cumbersome, easily
Error, on the other hand, existing sample-adding process can not keeping sample, if sample-adding process error, the later stage counter can not look into.
Therefore, applicant once applied for a kind of multi-purpose disposable blood transfusion cross match blood test combination on 2 13rd, 2015
Device, and patent for invention has been obtained, a kind of special combination tester is provided for cross matching experiment, but there is no at present special
Sample injector, but use and be manually loaded one by one, efficiency is low and easy error.
The content of the invention

Embodiment
Embodiment 1
Referring to Fig. 1, the present invention has the distribution pipe 3 of a horizontal positioned closed at both ends, is provided with least two side by side in distribution pipe 3
Individual syringe 2, syringe 2 is vertical with distribution pipe 3, and the syringe needle position of syringe 2 is located at the lower section of distribution pipe 3, injection through distribution pipe 3
The position being located on device 2 in distribution pipe 3 is provided with radial direction through hole, with syringe 2 side by side provided with a sample-adding pipe 1 in distribution pipe 3,
Sample-adding pipe 1 is communicated by distribution pipe 3 with syringe 2.
Syringe 2 described in the present embodiment is located at the sample-adding amount according to needed for experiment of the sample-adding volume below radial direction through hole and set
It is fixed.
The bottom of distribution pipe 3 described in the present embodiment is communicated provided with a storage capsule 4, storage capsule 4 with distribution pipe 3.
Operation principle：Sample is added in sample-adding pipe 1, sample is flowed into each syringe 2 naturally by distribution pipe 3,
Sample injector is directed at again the experimental group clutch of required sample-adding, successively pushing syringe 2, when the piston of syringe 2 shifts edge on through hole onto
When down promoting again, due to small many of radial direction through hole diameter above the aperture ratio of syringe needle position, therefore syringe needle position pressure ratio is radially led to
Big many of pressure at hole, so sample many in through hole is flowed into the storage capsule 4 of distribution pipe 3, up to the piston of syringe 2 shift onto it is logical
When hole lower edge is down pushed to bottom again, quantitative sample flows into experimental group clutch by syringe needle, now completes sample-adding.
When the present embodiment is used for ABO positive definite forms and the experiment of RhD bracket for blood grouping, operating procedure is as follows：
1st, take the ABO of Patent No. 201621065473.0 positive and negative and RhD antigens bloodtypes identification combiner one, in its three examinations
Pipe in be separately added into containing anti-D, anti-A, anti-B standard serum；
2nd, the sample injector of the present invention containing 3 syringes is taken, blood cell suspension to be measured is added in sample-adding pipe, then sample injector is put
The alignment test tube above combiner, successively adds the blood cell suspension in syringe in combiner；
3rd, combiner is placed on to take out after 15 minutes in 37 DEG C of insulating boxs and shaken up, then with 1000 turns/min centrifugally operateds；
4th, the situation that observation red blood cell sinks, such as substantially uniformity sinks down into ttom of pipe, and gel is uniformly distributed, then is judged as not aggegation；
It is judged as aggegation if the complete aggegation of red blood cell is on gel layer；As red blood cell disperses uneven aggegation among gel layer
It is judged as aggegation.
When the present embodiment is used for ABO reverse types and irregular antibody examination experiment, operating procedure is as follows：
1st, take the ABO containing three test tubes positive and negative and RhD antigens bloodtypes two groups of combiner of identification, and be emitted in rack for test tube, it is left
Side three is separately added into normal erythrocytes A, red blood cell B, red blood cell AB, and three, right side is separately added into containing anti-Igm and B1, B2, B3
The red blood cell of reagent；
2nd, the sample injector for taking structure as shown in Figure 5, adds serum sample to be measured into sample-adding pipe 1, is then directed at sample injector
The test tube mouthful of combiner, pushing syringe is loaded；
3rd, combiner is placed in 37 DEG C of insulating boxs 15 minutes, shaken up, with centrifuge 1000 turns/min centrifugally operateds, Ran Houqu
Go out observation, result of determination simultaneously keeps a record, then mark is "+" for aggegation, and then mark is "-" for not aggegation；
The positive reverse types of ABO and RhD blood groups and irregular antibody screening results judge as shown in the table：
