A kind of Multifunction sampling sample injector
The utility model relates to biologic medical utensil field, relates in particular to a kind of Multifunction sampling sample injector.
Sampling sample injector is generally used for sampling and the transfer of tested liquid in clinical examination, extraction and analysis experiment, generally by sampler barrel, imbibition nozzle, push away soup stick etc. and partly form, by rotation, push away soup stick and regulate liquid absorption, existing sampling sample injector is divided into microsampling sample injector and routine sampling sample injector, sample liquid has dust impurity and falls in the process of depositing, and the sampling syringe needle of microsampling sample injector is very little, in the process of sampling, is easy to be drawn onto these impurity and stops up sampling syringe needle; And the liquid absorption of routine sampling sample injector is not easy to control, makes washing lotion process produce error, thereby cause testing result also to occur certain error.
Summary of the invention
According to above technical matters, the utility model provides a kind of Multifunction sampling sample injector that degree of accuracy is high that samples, comprise sampler barrel, imbibition nozzle, level pushes away soup stick, it is characterized in that: also comprise sealing mounting hole, trace sampling apparatus, described trace sampling apparatus comprises microsampling cylinder, sampling syringe needle, vertically push away soup stick, O-ring seal, the lower end of described sampler barrel is provided with imbibition nozzle, the upper end of described sampler barrel is provided with sealing mounting hole, described level pushes away soup stick and stretches into sampler barrel and be spirally connected and be installed together from the horizontal opening end of sampler barrel, the outside of described microsampling cylinder is provided with O-ring seal, the lower end of described microsampling cylinder is provided with sampling syringe needle, the described soup stick that vertically pushes away stretches into microsampling cylinder and is spirally connected and is installed together from the upper end of microsampling cylinder, described trace sampling apparatus inserts and is arranged on sampler barrel from sealing mounting hole.
Described sampler barrel right angle cylindrical structure.
Described microsampling cylinder and sampler barrel coaxially arrange.
Described trace sampling apparatus and sampler barrel are detachable mounting structure.
The beneficial effects of the utility model are: the utility model improves on original sampling sample injector, in the upper end of sampler barrel, be provided with sealing mounting hole, both usable samples cylinder direct sample, by trace sampling apparatus, compensate or reduce the liquid volume in sampler barrel, sampling error while having reduced sampler barrel direct sample, thereby the error that has reduced testing result, has increased accuracy of detection; Also trace sampling apparatus can be arranged on sampler barrel by sealing mounting hole, during sampling, first by imbibition nozzle, filter liquid to be measured is sucked in sampler barrel, again by trace sampling apparatus imbitition from sampler barrel, reduce the impurity in liquid, thereby greatly reduced the possibility that sampling syringe needle is stopped up by impurity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Shown in Fig. 1, the utility model is further described:
As Fig. 1, sampler barrel-1, imbibition nozzle-2, level push away soup stick-3, sealing mounting hole-4, trace sampling apparatus-5, microsampling cylinder-6, sample syringe needle-7, vertically push away soup stick-8, O-ring seal-9.
The utility model comprises sampler barrel 1, imbibition nozzle 2, level pushes away soup stick 3, sealing mounting hole 4, trace sampling apparatus 5, trace sampling apparatus 5 comprises microsampling cylinder 6, sampling syringe needle 7, vertically push away soup stick 8, O-ring seal 9, sampler barrel 1 is right angle cylindrical structure, during installation, first imbibition nozzle 2 is arranged on to the lower end of sampler barrel 1, in the upper end of sampler barrel 1, offer a sealing mounting hole 4, level is pushed away to soup stick 3 to be stretched into sampler barrel 1 spiral shell and installs and be connected together from the horizontal opening end of sampler barrel 1, then O-ring seal 9 is arranged on to the outside of microsampling cylinder 6, sampling syringe needle 7 is arranged on to the lower end of microsampling cylinder 6, by vertically pushing away soup stick 8, from the upper end of microsampling cylinder 6, stretch into microsampling cylinder 6 and be spirally connected and be installed together, finally trace sampling apparatus 5 is inserted and is arranged on sampler barrel 1 from sealing mounting hole 4.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
