Abstract
The utility model discloses a micro-quantity sampler. The utility model is formed by connecting a glass burette, a plastic joint and a capillary tube. One end of the plastic joint is sheathed with an outlet of the glass burette, the capillary tube is inserted into the other end of the plastic joint, and a rubber nipple at the upper part of the burette is provided with a small hole. The capillary tube is a quantitative capillary tube and the quantity can be 5, 10 and 20 microlitres. The utility model which has the advantages of quick sampling, high accuracy, simple manufacture and strong practicability is convenient in being popularized and used in a laboratory of basic level.
Description
The utility model relates to the microscale sampler that a kind of medical test is used.
Along with popularizing of medical science biochemical investigation field semi-automated analysis instrument, microsampling has become the whether accurate key point of assay.Homemade 5～10 microlitre sampler precision are poor, have a strong impact on precision of analysis.The operation of glass microscale sampler is too slow, can not adapt to wide variety of conventional work.The higher import sampler of accuracy then is difficult to popularize because of costing an arm and a leg.
The purpose of this utility model provides a kind of simple in structure, the microscale sampler cheap, that sampling is rapid, accuracy is high.
The purpose of this utility model realizes in the following manner: a kind of microscale sampler, connect to form by glass dropper, adapter of plastic, kapillary, adapter of plastic one end and glass dropper outlet socket, kapillary inserts the adapter of plastic other end, and dropper top rubber nipple is provided with aperture.
Described kapillary is the quantitative kapillaries of 5,10,20 microlitres.
The utility model sampling rapidly, 5 microlitres of taking a sample about 1 seconds, about 1～3 second of 10 microlitres of taking a sample, 20 microlitres of taking a sample about 2～4 seconds, the accuracy height is done serum calcium repeatability and is measured, precision Sw=0.42, coefficient of variation CV=1.69% is specially adapted to end-point method and measures use.With the import sampler, Britain produces senior serial volumetric pipette control experiment: r=0.9981, through related coefficient (r) significance test, t
r=85.74＞t
0.01 (28)=2.763, P＜0.01 illustrates to be the height correlation relation between the two.The utility model is simple and easy to system, and is practical, is convenient to promote the use of in the basic unit laboratory.
Describe structure of the present utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
The utility model is made up of glass dropper 1, adapter of plastic 2, kapillary 3, rubber nipple 4 is equipped with on glass dropper 1 top, nipple 4 is provided with aperture 5, glass dropper 1 conical outlet and the 2 one end sockets of conical plastics joint, two-port cooperates closely, kapillary 3 inserts adapter of plastic 2 other ends, and kapillary 3 is the quantitative kapillaries of 5,10,20 microlitres.During sampling, sampler is inserted in serum or other measured object, utilized siphon principle, soup sucks kapillary automatically, is full of quantitative kapillary, and high-visible, pressure goes out a little then, can finish the primary sample process.Before using, the utility model, drains moisture then once with distilled water with the kapillary lavation.Must drain moisture in the kapillary before the sampling, otherwise influence siphon.Not stifled nipple aperture prevents to suck in the dropper during siphon.Idol has air bound can put nipple aperture help sample introduction gently.Sampling back care should be used to is wiped the outer adhering liquid of capillary wall, in order to avoid influence sampling accuracy.It is inferior to give a baby a bath on the third day after its birth with the distilled water suction with the back, can use repeatedly.
