Description
Technical field
The utility model relates to a kind of sample apparatus, is specifically related to a kind of self-suction type liquid sample micro quantitative determination sampling thief.
Background technology
At present in technical fields such as biological chemistry, chemical experiment or medicinal diagnosis, except blood, also have a lot of sample, such as various reagent, liquid etc., sample all needs to carry out quantitatively trace before detection and gathers.Usually the comparatively normal sampling thief adopted is latex dropper, and latex dropper is also called glue head dropper, Capsule dropper, and it is made up of Capsule and glass tube, for drawing or dripping a small amount of liquid reagent.
The sampling thief of said structure cannot realize the accurate micro quantitative determination collection of sample in use, and then affects testing result, and in gatherer process, sample easily pollutes environment or operating personnel, there is potential safety hazard.
Summary of the invention
The utility model object is to provide a kind of self-suction type liquid sample micro quantitative determination sampling thief, use this sampling thief, the self-priming micro quantitative determination collection of sample can be realized accurately, ensure that the accurate of testing result, and can not pollute surrounding enviroment and operating personnel in use procedure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of self-suction type liquid sample micro quantitative determination sampling thief, comprise both ends open and the sampling pipe be communicated with and air extrusion mechanism, described sampling pipe comprises both ends open and the capillary syring be communicated with and liquid storage pipe, the external diameter of described capillary syring is less than the internal diameter of described liquid storage pipe, the lower end of described liquid storage pipe coordinates with the upper end of described capillary syring inserts for it, and the side inwall of the upper end outer wall of described capillary syring and the lower end of described liquid storage pipe is fitted after inserting, liquid storage cylinder is formed between the opposite side inwall of the lower end of described liquid storage pipe and outer wall, described air extrusion mechanism is connected with the upper end of described liquid storage pipe, and described air extrusion mechanism offers pore.
Further technical scheme, described air extrusion mechanism is an air bag, and the upper end of described liquid storage pipe coordinates with the lower end of described air bag inserts for it, and the inwall of the upper end of the lower end outer wall of described air bag and described liquid storage pipe is fitted.
Further technical scheme, described air bag upper center offers pore.
Further technical scheme, the outer wall of the nearly lower end of described air extrusion mechanism is circumferentially provided with edge, and when the upper end of liquid storage pipe is inserted in the lower end of air bag, described edge is conflicted with the end, upper end of described liquid storage pipe and engaged.
Further technical scheme, described capillary syring can be the one in glass or plastics.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. the utility model is by arranging sampling pipe and air extrusion mechanism, sampling pipe is made up of capillary syring and liquid storage pipe, realize gathering into capillary syring by self-priming for sample by the pore in air extrusion mechanism, unnecessary sample then can flow in liquid storage pipe from the upper end of capillary syring, realize the self-priming collection of accurate micro quantitative determination, ensure that the accuracy of testing result;
2. the utility model is in sampling process, and the unnecessary sample being sucked into capillary syring can flow in liquid storage pipe along the inwall of the upper end of capillary syring and liquid storage pipe, avoids unnecessary sample to pollute surrounding enviroment and operating personnel, safer;
3. the utility model structure is simple, easy to use, is applicable to promoting the use of.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment one.
Wherein: 1, air extrusion mechanism; 2, capillary syring; 3, liquid storage pipe; 4, liquid storage cylinder; 5, edge; 6, pore.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one: shown in Figure 1, a kind of self-suction type liquid sample micro quantitative determination sampling thief, comprise both ends open and the sampling pipe be communicated with and air extrusion mechanism 1, described sampling pipe comprises both ends open and the capillary syring 2 be communicated with and liquid storage pipe 3, the external diameter of described capillary syring 2 is less than the internal diameter of described liquid storage pipe 3, the lower end of described liquid storage pipe 3 coordinates with the upper end of described capillary syring 2 inserts for it, and the side inwall of the upper end outer wall of described capillary syring and the lower end of described liquid storage pipe is fitted after inserting, liquid storage cylinder 4 is formed between the opposite side inwall of the lower end of described liquid storage pipe and outer wall, described air extrusion mechanism 1 is connected with the upper end of described liquid storage pipe 3, described air extrusion mechanism 1 is an air bag, the upper center of described air bag offers pore 6, the upper end of described liquid storage pipe coordinates with the lower end of described air bag inserts for it, and the inwall of the upper end of the lower end outer wall of described air bag and described liquid storage pipe is fitted, the outer wall of the nearly lower end of described air extrusion mechanism 1 is circumferentially provided with edge 5, and when the upper end of liquid storage pipe is inserted in the lower end of air bag, described edge is conflicted with the end, upper end of described liquid storage pipe and is engaged.
The utility model in use, capillary syring is put into sample to be collected by operating personnel, self-priming collection is realized by the pore in air extrusion mechanism, and then by sample from sucking in capillary syring, the specification of capillary syring can be arranged according to actual needs, can be 5 microlitres, 10 microlitres, 15 microlitres, 20 microlitres, 50 microlitres, 100 microlitres etc. need arbitrarily the capacity gathered, capillary syring upper end is inserted in liquid storage pipe lower end, and the side being close to liquid storage pipe is arranged, the benefit of such setting is when capillary syring carries out liquid assimilating, draw the unnecessary sample of coming in because near the internal wall tension of liquid storage pipe effect thus in liquid storage cylinder between the inner and outer wall that can flow to liquid storage pipe from the upper end of capillary syring along the inwall of liquid storage pipe, realize the self-priming collection of accurate micro quantitative determination of sample, and then ensure that the accuracy of testing result, and avoid unnecessary sample to pollute surrounding enviroment and operating personnel simultaneously, safer.
