In order to solve the above problem, the utility model discloses the technical scheme who takes as follows:
an integrated sampling and filling device comprises a liquid storage tube, a sealing liquid tube and a sampling capillary tube; the liquid storage tube is of a structure with a closed upper end and an open lower end, and broken ring grooves are arranged on the outer sides of the periphery of the upper part of the liquid storage tube; the lower end of the liquid storage pipe is connected with a sealed liquid pipe; the two ends of the upper end of the sealing liquid pipe are opened; the upper end of the sealed liquid pipe is connected with the upper end of the liquid storage pipe in a sealing and communicating way; the lower end of the sealing liquid pipe is hermetically sleeved with the upper end of the sampling capillary; the upper half part of the sealing liquid pipe is filled with sealing liquid; a reagent is injected into the liquid storage tube; the sealing liquid in the sealing liquid tube is sealed at the bottom of the reagent in the liquid storage tube; a vent hole is formed in one side of the lower half part of the sealing liquid pipe; the vent hole is positioned above the sampling capillary tube.
Further, the liquid storage tube and the sealing liquid tube are made of one of PC, PP, PE, PMMA, PVC and the like.
Furthermore, the sampling capillary is made of one of glass, quartz, plastic, stainless steel and the like.
Further, the sealing liquid in the sealing liquid tube is one of liquid paraffin, silicone oil, vaseline and the like.
The beneficial effects of the utility model
The utility model simplifies the whole structure while integrating the processes of sampling, reagent filling and sample transferring, collects quantitative samples through the sampling capillary tube, samples can fill the inside of the sampling capillary tube due to capillary phenomenon, at the moment, the reagent in the liquid storage tube and the sealing liquid in the sealing liquid tube cannot flow out under the action of atmospheric pressure due to the sealing state at the upper end of the liquid storage tube, then the utility model is moved to the position right above the sample detection device in a vertical state with the sampling capillary tube facing downwards, and then the annular groove is broken along the outer side of the upper part of the liquid storage tube to break the upper end of the liquid storage tube, at the moment, the atmospheric pressure at the upper and lower ends of the liquid storage tube, the sealing liquid tube and the sampling capillary tube reaches balance, the reagent in the liquid storage tube flows downwards due to the influence of gravity, and the sealing liquid in the sealing liquid tube and the samples in the sampling capillary tube are pushed to drop into the detection device, so realized the integration of adoption and filling and gone on, moreover the utility model discloses structural design is simple and light and handy, with low costs, convenient to use, has wide market prospect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, an integrated sampling and filling device comprises a liquid storage tube 1, a sealing liquid tube 2 and a sampling capillary tube 3; the liquid storage tube 1 is of a structure with a closed upper end and an open lower end, and broken ring grooves 11 are arranged on the outer side of the periphery of the upper part of the liquid storage tube 1; the lower end of the liquid storage tube 1 is connected with a sealed liquid tube 2; the two ends of the upper end of the sealing liquid pipe 2 are open; the upper end of the sealed liquid pipe 2 is connected with the upper end of the liquid storage pipe 1 in a sealing and communicating way; the lower end of the sealing liquid pipe 2 is hermetically sleeved with the upper end of the sampling capillary 3; the upper half part of the sealing liquid pipe 2 is filled with sealing liquid; a reagent is injected into the liquid storage tube 1; the sealing liquid in the sealing liquid tube 2 is sealed at the bottom of the reagent in the liquid storage tube 1; a vent hole 21 is formed in one side of the lower half part of the sealing liquid pipe 2; the vent 21 is located above the sampling capillary 3. Further, the liquid storage tube 1 and the sealing liquid tube 21 are made of one of PC, PP, PE, PMMA, PVC, etc., and may be integrally formed, which may be reasonably selected by those skilled in the art. Further, the sampling capillary 3 is made of one of glass, quartz, plastic, stainless steel and the like, and can be reasonably selected by a person skilled in the art. Further, the sealing liquid in the sealing liquid tube 2 is one of liquid paraffin, silicone oil, vaseline, etc., and those skilled in the art can select other liquids having the same sealing effect to perform sealing.
The utility model simplifies the whole structure while integrating the processes of sampling, reagent filling and sample transferring, collects quantitative samples through the sampling capillary tube 3, samples can fill the inside of the sampling capillary tube 3 due to capillary phenomenon, at the moment, the reagent in the liquid storage tube 1 and the sealing liquid in the sealing liquid tube 2 can not flow out due to the sealing state at the upper end of the liquid storage tube 1, the sealing liquid in the liquid storage tube 2 is acted by the atmospheric pressure at the lower end of the sealing liquid, then the utility model is moved to the right top of the sample detection device in the vertical state that the sampling capillary tube 3 faces downwards, and then the upper end of the liquid storage tube is broken along the broken annular groove 11 at the outer side of the periphery of the upper part of the liquid storage tube 1, at the moment, the pressures at the upper end and the lower end of the liquid storage tube 1, the sealing liquid in the sampling capillary tube 2 and the samples in the sampling capillary tube 3 reach balance, the reagent in the liquid storage tube 1 flows downwards due to the influence of gravity, and pushes the sealing liquid in the sealing liquid storage tube 2 and the samples in the sampling capillary tube 3 to drip into the detection device, so realized the integration of adoption and filling and gone on, moreover the utility model discloses structural design is simple and handy, with low costs, convenient to use, has wide market prospect.
