Description
Technical field
The present invention relates to a kind of being used for distributes the hyperchannel that detects sample to divide the blood device to the sense channel of blood analyser, the invention still further relates to a kind of being used for to distribute the hyperchannel that detects sample to divide the blood method to the sense channel of blood analyser.
Background technology
Have the type composition to comprise red blood cell, leucocyte, blood platelet in the blood of human body, every kind of cell all has the different clinical meaning, and the concrete takeoff of above-mentioned cell is come out us need be by blood analyser.
Blood analyser is drawn blood sample through suction needle, and three-classification blood analyzer is only drawn a segment mark usually originally can accomplish detection; Five classification blood analyzers need be accomplished detection owing to need test item more in several sense channels, therefore need absorption multistage blood to be assigned to different passages by different volumes or equal volume and detect.
Thereby existing five classification blood analyzer major parts are to adopt a kind of rotary valve to come intercepting to go out the purpose that several sections blood reach branch blood.But their main shortcomings are the rotary valve structure more complicated, also need often to clean, and this all is to be difficult to implement in processing and operational maintenance.
Summary of the invention
The technical matters that the present invention will solve is: provide a kind of hyperchannel to divide the blood device, make that it is simple in structure, be easy to safeguard, also provide a kind of hyperchannel to divide the blood method, make it simple to operate.
Hyperchannel of the present invention divides the blood device to comprise reagent sampler, blood sample sampler and is used to receive the reagent of reagent sampler distribution and the storage of the blood sample that the blood sample sampler distributes; The blood sample sampler comprise by the micro syringe of stepper motor I control piston motion with the suction needle that outlet is connected that is injected into of micro syringe, suction needle is marked with a plurality of volume marking line.
In order to be equipped with rich blood sample, prevent to cause blood sample to distribute inadequately because of error or loss, the lower end of described suction needle is separated into a plurality of pipeline sections by a plurality of volume marking line, and the number of pipeline section is Duoed one at least than passage number to be allocated.
For the ease of distributing reagent, described reagent sampler comprise by the syringe of stepper motor II control piston motion with the nozzle that outlet is connected that is injected into of syringe.
For easy to operate, described suction needle is connected with the outlet that is injected into of micro syringe through the delivery hose I, and described nozzle is imported and exported with injector to inject through the delivery hose II and is connected.
The blood method of dividing hyperchannel of the present invention adopts aforementioned any hyperchannel to divide the blood device; This method comprises the steps: that a extracts a certain amount of reagent in the reagent sampler; Through stepper motor I and micro syringe blood sample is drawn into suction needle, blood sample enters into the position of going up a volume marking line on the suction needle most; B inserts storage with suction needle; Storage is inserted in the outlet of reagent sampler; Opening the stepper motor I makes the blood sample in the suction needle drop to next volume marking line; The blood sample that flows out forms drop and is suspended on the suction needle bottom; Reagent sampler ejection reagent is flushed to the droplet of suction needle bottom in the storage; Form the homomixture of blood sample and reagent, accomplish the branch blood of a passage; C gets storage in addition or the material in first storage has detected the back through blood analyser and purified back recycling first storage; The carrying out of b repeatedly divided blood set by step again; Volume marking line of blood sample decline in each branch blood suction needle is divided equally blood until the sense channel of blood analyser needs and is finished.
Beneficial effect of the present invention: the present invention divides the blood device to be made up of reagent sampler, blood sample sampler and storage; Simple in structure; Adopt the suction needle of stepper motor and micro syringe control to get blood and distribute blood sample; Need the volume of blood sample few; When safeguarding; The blood sample sampler only need clean suction needle, and cleans easily, is easy to safeguard.The present invention divides the blood method to adopt the blood sample sampler to distribute blood sample; Adopt the reagent sampler to distribute reagent, and dash through the drop of ejection reagent with blood sample, simple to operate; The umber that blood sample distributes and the volume of every part of blood sample have very big dirigibility, can adjust according to actual needs.

Fig. 1 is a structural representation of the present invention;
Among the figure: 1, nozzle, 2, suction needle, 3, the delivery hose I, 4, the stepper motor I, 5, micro syringe, 6, storage, 7, the stepper motor II, 8, syringe, 9, the delivery hose II.
Embodiment
A kind of hyperchannel as shown in Figure 1 divides the blood device; It comprises reagent sampler, blood sample sampler and storage 6; The reagent sampler comprises nozzle 1, stepper motor II 7, syringe 8 and delivery hose II 9, and the blood sample sampler comprises suction needle 2, delivery hose I 3, stepper motor I 4 and micro syringe 5.The reagent sampler also can adopt other structure, as long as have the function that extracts reagent and ejection reagent.
The piston of micro syringe 5 connects the stepper motor I 4 of the piston motion that drives micro syringe 5; The outlet that is injected into of micro syringe 5 connects suction needle 2 through delivery hose I 3; Suction needle 2 is marked with a plurality of volume marking line; The lower end of suction needle 2 is separated into the multistage body by a plurality of volume marking line; Every section body volume is 20-40ul; Every section volume is with identical, and is also different, need be confirmed by the detection of blood analyser.Blood sample in uppermost one section body is rich blood.The blood sample of other pipeline section is used for distributing.The number that is pipeline section is Duoed one than passage number to be allocated.The volume of micro syringe 5 is not less than the volume sum of each section body.
The piston of syringe 8 connects the stepper motor II 7 of the piston motion of injector-actuated 8; The outlet that is injected into of stepper motor II 7, syringe 8 connects nozzle 1 through delivery hose II 9, and storage 6 is used to receive from the reagent of nozzle 1 ejection and the blood sample that sprays from suction needle 2.
Shown in Figure 1 multichannel device of the blood serum is as follows: The method includes the following steps: a certain amount of reagent is drawn into the syringe 8, the stepping motor 5 Ⅰ 4 and trace the blood drawn into the syringe suction syringe 2 , suck blood into the syringe two most marked on a volume line position; b 2 into the suction syringe receptacle 6, the nozzle an oblique insertion receptacle 6, so that the outlet nozzle diagonally a suction syringe two at the bottom, turn the stepper motor Ⅰ 4 suction syringe to make the blood drops 2 next volume dimension line, out of the blood to form droplets suspended in the bottom of suction syringe 2, because the amount of blood is small, easy to automatically drop droplet into the receptacle 6, and then turn the stepper motor Ⅱ 7 spray nozzle a reagent (usually around 2ml by blood analyzer detection need to determine), ejected reagent suction syringe two rushed to the bottom of the reservoir droplet 6 is, the formation of a blood sample and reagent mixing things, the completion of a channel of blood; c Another receptacle 6 or 6 in the first receptacle of substances through the blood analyzer and purified reused after the first a receptacle 6 (6 receptacles blood analyzer detection channel), and then conducted a number of step b blood, until the suction syringe 2, last paragraph wealthy leftover blood, blood analyzers are each detection channel get of the blood.
