Abstract
The invention discloses an integrated puncturing piston type sampling and injecting device. The device sequentially comprises a press button, a rubber piston, a piston barrel, a capillary syringe and an injection opening from top to bottom, wherein the capillary syringe and the injection opening are arranged at the bottom of the piston barrel. According to the integrated puncturing piston type sampling and injecting device disclosed by the invention, the operation from collection to reaction of a sample is simplified, so that the operation is simple and convenient and is easy to grasp; the adding precision of a reagent is improved; the preparation time of detection in an early stage is shortened.
Description
Technical field
The present invention relates to a kind of accurate microsampling and the quantitative device that adds reagent, specifically piston type sampling filling apparatus.
Background technology
Domestic and international existing routine techniques scheme, normally reagent and cuvette are separated, and reason is that reagent needs refrigeration, guarantees to never degenerate, and generally can leave in the special agent bottle, and place special refrigeration place refrigeration.Cuvette is disposal plastic cup or nonvolatil glass cylinder, uses special-purpose pipettor will refrigerate the reagent sucking-off during work, be expelled in the cuvette, and sample fully reacts, again by its variation of optical system detection with measure its content or composition again.
The equipment such as tradition filling reagent and collecting sample normal operation pipettor, transfer pipet generally need the liquid shifting equipment of two or more to finish testing process during detection, have complex operation, the easy shortcoming of polluting and make mistakes etc.
Summary of the invention
The objective of the invention is the deficiency for the prior art existence, provide a kind of and simplify the operation course, avoid to pollute, and realize the functions such as accurately sampling, quick application of sample, reagent adding, easy integrated lancing piston type reliable, with low cost sampling filling apparatus.
For achieving the above object, the integrated puncture piston type sampling of the technical solution used in the present invention filling apparatus, the capillary syring and the injection port that comprise button, rubber plug and the piston cylinder that sets gradually from top to bottom and be arranged on the piston cylinder bottom.
Described button and rubber plug interference fit.
Described capillary syring is dismountable piston cylinder bottom that is installed in.
Described injection port bottom also is provided with the injection port stopper.
Rubber plug and button interference fit are inserted in the piston cylinder again.The cylindrical protrusion of piston cylinder both sides is moved in the chute of button both sides; Sealing ring on the rubber plug and piston cylinder interference fit play the effect of sealing.Capillary syring is contained on the piston cylinder, and closely cooperates.Injection port interference fit on injection port stopper and the piston cylinder.
In rubber plug, piston cylinder and the molecular confined space of injection port plug, accurate trace reagent is housed.As long as button is pressed, rubber plug can increase the pressure in the confined space during use, finally the injection port stopper can be backed down, and the reagent in the confined space will inject cuvette automatically from injection port.
The head of capillary syring has the kapillary of a constant volume, and near blood, blood also will fill up in the pipe in the tail pipe automatically with capillary syring.Inject cuvette reagent will with reaction of blood.
Beneficial effect: the present invention has simplified sample from collecting the operation of reaction, so that left-hand seat easy and simple to handle, easy; Improved the adding precision of reagent; Reduced the setup time of detecting early stage.
Description of drawings
Fig. 1 is cut-open view of the present invention;
Fig. 2 is stereographic map of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, the present embodiment is implemented under take technical solution of the present invention as prerequisite, should understand these embodiment and only be used for explanation the present invention and be not used in and limit the scope of the invention.
As depicted in figs. 1 and 2, integrated lancing piston type sampling filling apparatus, comprise button 1, rubber plug 2 and the piston cylinder 3 and the capillary syring 5 that is arranged on piston cylinder 3 bottoms and the injection port 6 that set gradually from top to bottom, capillary syring 5 dismountable piston cylinder 3 bottoms that are installed in, be provided with injection port stopper 4 in the injection port 6, button 1 and rubber plug 2 interference fit.
When producing, piston cylinder 3 injects a certain amount of reagent in advance with the cavity in the middle of the rubber plug 2 is interior, and with injection port stopper 4 injection port 6 is blocked.So that when the work, reagent is in the confined space.
During use, as long as behind the capillary syring 5 close blood with this charging point, because capillarity, blood can fill up really kapillary automatically, obtains quantitative blood sample.Then this charging point is inserted among cuvette, the sealing ring on the piston cylinder 3 can with the cuvette interference fit so that sample can be enclosed in the cuvette.
Then press the button 1 on the charging point, the reagent in the cavity of packing in advance will inject cuvette automatically.Shake up gently reagent.Shake up in the process, the liquid in the cuvette can be blocked by three block wings on the capillary syring, and along block wing, liquid can flow to kapillary, and wherein sample is fully reacted.Conveniently can detect afterwards.
