Description
Technical field
The present invention relates to the automated fluid operating means, can accurately realize the preparation of multiple liquid, be applied to chemistry, biology, disease control, metering, quality inspection, laboratory such as clinical.
Background technology
Often need carry out a large amount of fluid operatedly in chemistry, biology, disease control, metering, quality inspection, laboratory such as clinical, comprise separatory, dilution, titration, move liquid etc.Especially along with the increase of present various epidemic diseases such as SARS, first stream etc., biochemical test is had higher requirement.And traditional manual mode based on liquid-transfering gun, the operating process complexity, inefficiency, the labour intensity height causes operate miss easily, and this on the other hand manual mode of operation has also increased the risk that the operator infects.
More existing semi-automatic liquid operating devices on the market, as Switzerland Hamilton, French Gilson, Japanese NICHIRYO, the semi-automatic liquid diluting instrument that companies such as Spain IUL release, liquid separating meter etc. can improve fluid operated efficient greatly, reduce labor intensity of operating personnel.
The product principle of each company is similar, roughly is divided into following a few class:
One, single channel type
Its principle as shown in Figure 1, fluid operated instrument comprises syringe pump (1), valve (2), buffer solution pipeline (3), sample liquid pipeline (4) is formed.The end of general sample liquid pipeline (4) is fixed on the operating grip (5), and handle (5) comprises that further a button (501) is used for the user and instrument carries out alternately sometimes.Wherein, syringe pump (1) is driven by precision stepper motor (11) and realizes precision reciprocating.Valve (2) comprises three ports, public port (com), normally closed port (nc), often ported (no), wherein, public port (com) links to each other with syringe pump (1), normally closed port (nc) links to each other with buffer solution port (3), and often ported (no) links to each other with sample liquid pipeline (4).Valve (2) realizes that by powering up, cutting off the power supply public port (com) and the passage of often opening between (no), normally closed (nc) port switch.Buffer solution port (3) is directly put into the container that buffer solution is housed.
Realize the fluid operated of various complexity by control like this, as dilution, separatory, application of sample etc. to syringe pump (1), valve (2) and handle button (501).In dilution, application of sample process, generally sample collection need be stored in the sample liquid pipeline (4) temporarily, therefore need the sample liquid pipeline that enough length is arranged, illustrate in order to helix in the drawings.
Two, two autonomous channel type
Its principle as shown in Figure 2, this series products has two autonomous channels separately, promptly syringe pump (1), valve (2), buffer solution pipeline (3), sample liquid pipeline (4) are formed first passage; Syringe pump (1 '), valve (2 '), buffer solution pipeline (3 '), sample liquid pipeline (4 ') are formed second channel.Two buffer solution pipelines (3), (3 ') connect different solution respectively, are illustrated as solution A, solution B in the drawings.The sample liquid pipeline (4) of two passages, the end of (4 ') all are fixed on the operating grip (5).
This series products lays particular emphasis on operations such as the preparation, application of sample of two kinds of liquid, two kinds of sample solutions respectively with two independently passage be connected, can avoid the cross pollution of two kinds of liquid in use, and improve dosing speed to a certain extent.This series products is not owing to exist the problem of sample being collected storage temporarily, and therefore the length to sample liquid pipeline (4), (4 ') does not have particular requirement.
Three, binary channels " cascade " type
Its principle as shown in Figure 3, this series products has two each passages, promptly syringe pump (1), valve (2), buffer solution pipeline (3) are formed first passage; Syringe pump (1 "), three-way connection (6), sample liquid pipeline (4) are formed second channel.Three-way connection (6) comprises three interface (a) and (b) that are interconnected, (c), and wherein interface (b) and syringe pump (1 ") link to each other interface (c) and sample liquid pipeline (4).By valve (2) Chang Kaiduan (no) and " cascade " that realize two passages being communicated with of three-way connection (6) interface (a).
This series products lays particular emphasis on the application scenario of dilution for many times, the volume of syringe pump (1 ") is less than the volume of syringe pump (1); syringe pump (1 ") is mainly used in the collection sample, and syringe pump (1) is used to inject dilution, therefore still can guarantee precision in highly diluted in than dosing process.
By above analysis to existing product, there is the problem of a general character as can be seen, promptly syringe pump lowers because of the operating efficiency that moves to the extreme position backhaul and cause.
With Fig. 1 for instance, when the piston arrives top of syringe pump (1), this moment if desired by operating grip (5) to an empty test tube (not shown) distributing buffer liquid 5ml, its operating process is as follows:
A. earlier with magnetic valve (2) outage, switch to buffer solution pipeline (3), syringe pump is resorption 5ml at least;
B. magnetic valve (2) powers up then, switches to sample liquid pipeline (4), and syringe pump (1) is released 5ml.
In this process, steps A is the backhaul operation of carrying out because syringe pump has moved to extreme position, and the user can only bear with during this period, thereby has reduced operating efficiency.
In addition, in a fluid operated task, syringe pump might need to move back and forth, and moves back and forth the hysterisis error of bringing and also can reduce the dosing precision, and this problem is particularly evident on single pass operation instrument.
Summary of the invention
The present invention is intended to design a kind of double injection pump configuration of novelty, this double injection pump all can independently be communicated with buffer solution pipeline and sample liquid pipeline: when first passage syringe pump was carried out fluid operated task, the second operating walk way syringe pump resetted and enters continued state; When first passage syringe pump reached the limit of the position, system switched to second operating walk way and continues the current operation task of execution and need not the user to wait for that first passage then resets and enters continued state.Go round and begin again like this, two operating walk ways have one all the time in the executable operations task, and another one enters continued state, thereby avoid syringe pump to descend because of the operating efficiency that causes when extreme position needs backhaul.
Specific implementation of the present invention is as follows:
