Description
Technical field
The utility model relates to for pick-up unit, the especially pick-up unit of Fast Measurement biochemical indicator of measuring the clinical physiological index.
Background technology
At present, the drying chemical reagent paper detection method often is used to measure whether have certain composition or this component content in the liquid sample, for example measures glucose in the blood sample, cholesterol, triglyceride equal size.
Drying chemical reagent paper is different according to disposable measurable sample size and testing index kind, is divided into the test paper of measuring single analyte and the test paper of measuring a plurality of analytes.For example US Patent No. 7087397 disclosed single analyte test papers are used for measuring blood middle-high density fatty acid.Also comprise the device that loads test paper in this piece United States Patent (USP), described device has the upper plate of well and has the lower plate of view window, is pressing the test paper of measuring high density fat acid between upper plate and lower plate.If measure biochemical indicators different in the same sample, when for example measuring simultaneously high density fat acid, low density fat acid, content of triglyceride, then must measure with three described pick-up units of US7087397.When need are measured a plurality of biochemical indicator simultaneously, use this class single analyte test paper can affect detection efficiency.In US Patent No. 7625721 embodiment illustrated in fig. 8, different single analyte test papers is incorporated in the device the corresponding well of each test item.The pick-up unit of this structure can reduce the consumption of pick-up unit, avoids using the mistake that does not match pick-up unit.But the operator still will add sample one time to each test item respectively.For example detect three projects, will drip sample three times.Therefore the workload that adds sample is still very large.
US6524864 and US7494818 all disclose the pick-up unit that application of sample just can be finished a plurality of test events.The US6524864 patent comprises a well and a plurality of test block, and increases a Distribution Layer between well and a plurality of test block, and this Distribution Layer can be assigned to the sample that drips on a plurality of reagent pieces equably.Such structure has realized only adding a sample and has finished a plurality of detection purpose functions.In the US7494818 patent, disclosed too the pick-up unit of realizing above-mentioned functions, realize that by Distribution Layer sample distributes on a plurality of test modules.This design that increases Distribution Layer at well and reagent interblock can make many procedures in the production run of assembling detection device, not only affects the production cycle, also may increase in process of production the contaminated probability of reagent piece.
There is not the liquid Distribution Layer in Figure 34 of US Patent No. 5962215 in well and a plurality of reagent piece to embodiment shown in Figure 36, but realize that by the groove in the upper plate liquid of liquid between a plurality of test modules distributes.When the fluid sample that adds transmitted in groove, the gas that originally was present in the groove was discharged at the opening at upper plate two ends by groove, thereby the air resistance that reduces in the groove is realized the transmission of liquid in groove smoothly.If the sample size that adds in the described mode of this patent is excessive, the sample that the reagent piece has little time to absorb will flow out from the opening part of upper plate two ends groove, has not only polluted surrounding environment, also may be infected with operator's cause danger.
Another weak point is, and is different for the employed chemical reagent of different test items, therefore as its degree of expansion of carrier material of reagent piece also can be because of the difference of processing chemical reagent thereon difference.To shown in Figure 36, when having arranged a plurality of reagent piece on the test paper, may cause the upper surface of different reagent pieces not on the same level face such as US5962215 patent Figure 34.If the distance between the height heterogeneity of test block, test block upper surface and loam cake groove is just not identical.At the large position of upper surface and groove distance, the speed of fluid transport is slow.At the little position of upper surface and groove distance, the speed of fluid transport is just slow.The difference of fluid transport speed just can not be controlled so that each reagent piece receives the time of sample, causes the time of obtaining test result uncontrollable, causes puzzlement for result's the time of reading, and has affected the accuracy of test result.
Do not have in the prior art the reagent occluding device between the different detection zones, when liquid when test paper transmits, the reagent in the different detection zones will enter on other the detection zone along with the transmission of liquid, has polluted other detection zone.
In addition, in existing product and disclosed document, for example in the described patented claim of US20080112848A1, the parts of the periphery of pick-up unit and detector shown in Figure 20 all are that hard and incompressible material are made.If make pick-up unit successfully put into detector and again can be from easily landing of detector, this just requires that the very high goodness of fit is arranged between pick-up unit and the detector.In the process of producing, if its size of a certain batch pick-up unit during greater than the value of in advance design, this batch pick-up unit just can not insert in the detector smoothly, can only do and scrap processing.If the size of a certain batch pick-up unit during less than the value of in advance design, although can be inserted into smoothly in the detector, because size is little, is easy to landing from detector.Same, if detector is processed to such an extent that be not very accurate, can occur also that above-mentioned detection device can not be inserted or the easy phenomenon of landing from detector of pick-up unit.Therefore for pick-up unit of the prior art and detector, the error range that allows in the production run is very little, and this just proposes very high requirement to production technology, increased production cost, otherwise the scrappage of product can be higher, has increased the cost of material.
