Abstract
The utility model discloses a quantifying straw and relates to the field of medical examination devices. An air bag and a reservoir are arranged at the upper end of the quantifying straw; the air bag and the reservoir are connected with a first reinforcing rib through gas conduits; the right end of the reservoir is connected with a second reinforcing rib and a liquid conduit; a small hole which is communicated with the liquid conduit is arranged at the upper end of the reservoir; the lower end of the liquid conduit is connected with a capillary tube; a vent pipe is arranged in the second reinforcing rib; and the end of the vent pipe is communicated with the liquid conduit through an opening. The quantifying straw is simple in structure, convenient in operation, high in precision and capable of realizing secondary quantifying and effectively reducing the testing error.
Description
Technical field
The utility model relates to a kind of medical inspection device, especially relates to a kind of quantitative suction pipe.
Background technology
In the check analysis field, usually need the micro quantitative determination sampling, after sample is diluted as requested, need quantitatively be added drop-wise in the reagent or container of analyzing usefulness, detect analysis.Because the volume difference of sampling needs to adopt two kinds of proportional sampling devices or changes measuring of pipettor material to carry out two sub-samplings and dropping usually, complicated operation, the requirement of equipment is also higher.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of quantitative suction pipe, can carry out the micro quantitative determination sampling on the one hand, can also quantitatively drip sample.
The technical scheme that the utility model technical solution problem adopts is: quantitatively the suction pipe upper end is provided with air bag and reservoir, air bag is connected with first reinforcement by gas conduit with reservoir, right-hand member at reservoir is connected with second reinforcement and liquid conduits, the reservoir upper end has aperture and is communicated with liquid conduits, lower end at liquid conduits is connected with capillary, be provided with breather pipe in second reinforcement, the breather pipe end is communicated with liquid conduits by opening.
Described air bag and reservoir are elliposoidal.
The diameter of described breather pipe less than with diameter capillaceous, the breather pipe end is higher than capillary end, is conducive to sample liquid and is full of whole capillary.
Certain length is stretched out in described capillary bottom, preferred 5mm.
The volume of described capillary splendid attire solution is fixed, preferred 10 ul or 15 ul.
The volume of described liquid conduits and described capillary associating carrying liquid is fixed preferred 80 ul or 100 ul.
The beneficial effect that the utility model has is:
The utility model is simple in structure, and is easy to operate, realizes second metering, and the accuracy height reduces verify error effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Figure of description the utility model is elaborated.
Described quantitative suction pipe upper end is provided with air bag 1 and reservoir 2, air bag 1 is connected with first reinforcement 4 by gas conduit 3 with reservoir 2, right-hand member at reservoir 2 is connected with second reinforcement 5 and liquid conduits 6, reservoir 2 upper ends have aperture and are communicated with liquid conduits 6, be connected with capillary 7 in the lower end of liquid conduits 6, be provided with breather pipe 8 in second reinforcement 5, breather pipe end 80 is communicated with liquid conduits 6 by opening.
In use, at first quantitative suction pipe is gently taken, tilted the capillary external part is immersed in the fluid sample, treat that the sample thief liquid level must be lower than the breather pipe bottom, this moment, liquid slowly was full of capillary, and volume is 10 ul(or 15 ul); Fluid sample is entered in the buffer solution by extruding gasbag, and extruding gasbag makes sample and buffer solution mixing for several times repeatedly, as requested dilution; Then, will get dilution by the air bag effect and suck, and fill with conduit, the liquid that suck are stored in reservoir more, by extruding gasbag liquid are entered in test agent or the container again, and the liquor capacity that get rid of this moment is 80 ul(or 100 ul), realize quantitatively.
