Abstract
The utility model provides a puncturing piston type sample feeding and sampling device which is formed by a sampling needle (1), a sealing aluminum film (2), a piston cylinder (3), a puncturing piston (4), a sealing ring (5) and a pressing cover (6), wherein the sampling needle (1) is mounted in a sampling needle groove (11) of the piston cylinder (3); a groove (10) of the puncturing piston (4) is provided with the sealing ring (5) and is connected into a cylinder cavity (8) of the piston cylinder (3); a certain amount of a reagent is injected into the cylinder cavity and the sealing aluminum film (2) covers; and the pressing cover (6) is mounted at the head of the puncturing piston (4). According to the puncturing piston type sample feeding and sampling device provided by the utility model, accurate sampling of trace samples and quantitative sample feeding of the reagent can be finished at the same time, and the puncturing piston type sample feeding and sampling device has the advantages of simplicity and convenience in operation, guaranteed precision and low cost.
Description
Affiliated technical field
The utility model relates to a kind of quantitative adding reagent and the accurate integrated apparatus of sampling of trace, specifically is a kind of function that realizes quantitatively adding reagent and accurate collection sample in units such as laboratory, hospital laboratories when detecting.
Background technology
Tradition adds reagent and gathers sample and generally use equipment such as transfer pipet, pipettor, generally needs the liquid shifting equipment of two or more to finish testing process during detection, has complex operation, the shortcoming of polluting and make mistakes etc. easily.
Summary of the invention
In order to solve existing issue, the utility model provides a kind of puncture piston type application of sample and sampling apparatus, realize accurately sampling, fast application of sample, add function such as reagent, easy to be reliable, with low cost.
The technical scheme that its technical matters that solves the utility model adopts is: the utility model is made up of sampling needle (1), sealed aluminum film (2), piston cylinder (3), puncture piston (4), O-ring seal (5) and press cover (6).The puncture tip (9) of puncture piston (4) be semi-annular shape and size less than the internal diameter of tube chamber (8), when the piston (4) that punctures was installed in the piston cylinder chamber (8), also having living space can store reagents.Kapillary sampling needle (1) carries out accurately sampling of trace with the kapillary of different inner diameters and length.Sampling needle (1) is installed in the sampling needle tray (11) of piston cylinder (3), install O-ring seal (5) on the groove (10) of puncture piston (4), pack into then in tube chamber (8) of piston cylinder (3), in the tube chamber, inject quantitative reagent, seal up sealed aluminum film (2), install press cover (6) at the head of puncture piston (4).
Earlier gather required sample with the kapillary (7) on the sampling needle (1) during use, react earlier with the reagent in the reaction cup, press press cover (6) then downwards, puncture tip (9) on the puncture piston (4) punctures diaphragm seal (2), pre-packaged reagent in the tube chamber (8) of piston cylinder (3) is pushed into reaction cup, react again, carry out next step detection then.
The beneficial effects of the utility model are, can finish the accurate sampling of micro-sample and the quantitative application of sample of reagent simultaneously, have easy and simple to handle, guarantee precision and advantage with low cost.
