Abstract
The utility model discloses micro-sampler for medical inspection, the sampler includes syringe, pushes away column, piston, the piston is placed in syringe and is connect with column is pushed away, it is provided with needle tubing at the top of the syringe, probe tube is provided in syringe, the probe tube bottom opening is connect with needle tubing, probe tube open top and conducting in syringe, the sampling pipe diameter to form cushion space between probe tube and syringe less than syringe diameter, for the piston along syringe in up and down motion pipette samples to probe tube, the liquid more than probe tube volume is stored in cushion space.Micro quantitative determination sampling may be implemented in this programme, improves testing accuracy.
Description
Technical field
The utility model is related to field of medical examination more particularly to micro-sampler for medical inspection.
Background technology
Currently, oneself carries out biochemical investigation, wherein microsampling just very extensively using automatic analyzer in medical test
Key, it be related to inspection result it is accurate whether, some samples needs carried out under conditions of being protected from light move sample sampling, slightly not
It is careful to cause sample rotten, and then the accuracy of inspection result is influenced, it carries out needing microsampling when micro assay analysis
Sampling is matched, but the prior art is often poor using common sampler quantization property, simultaneously because the unprotect of needle body is picked and placeed,
Cause to be easy inside fetching device contaminated.
Invention content
In view of this, the purpose of this utility model is to provide micro-sampler for medical inspection, micro quantitative determination may be implemented and take
Sample improves testing accuracy.
The utility model solves above-mentioned technical problem by following technological means：
A kind of micro-sampler for medical inspection, the sampler include syringe, push away column, piston, and the piston is placed in syringe
And connect with column is pushed away, it is provided with needle tubing at the top of the syringe, probe tube, the probe tube bottom opening and needle are provided in syringe
Pipe connects, and probe tube open top makes probe tube and syringe with conducting, the sampling pipe diameter in syringe less than syringe diameter
Between form cushion space, the piston is more than probe tube volume in up and down motion pipette samples to probe tube along syringe
Liquid is stored in cushion space.
Preferably, the probe tube is made of the fixed spherical column of capacity.
As being further improved for this programme, the piston is moved downward along syringe until being abutted with probe tube open top
Until.
The beneficial effects of the utility model：It is compared with traditional sampler, it is micro fixed that the advantage of this programme is may be implemented
Sample is measured, sample is drawn in probe tube by piston, probe tube is that quantitative sampling pipe is to meet the dosage standard examined,
More than the sample of probe tube capacity because the suction of piston enters in cushion space in suction process, when discharging sample, pushes and live
Plug squeezes out the sample in probe tube, and the sample in cushion space can not be squeezed due to not being connected directly between needle tubing
Go out, completes micro quantitative determination sampling, and sample accurate.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in detail below with reference to attached drawing：
As shown in Figure 1：
A kind of micro-sampler for medical inspection, the sampler include syringe 100, push away column 103, piston 102, the piston
102 are placed in syringe 100 and are connect with column 103 is pushed away, and 100 top of the syringe is provided with needle tubing 201.I.e. by syringe 100, push away column
103, piston 102 forms the structure of a syringe, identical as conventional syringe structure, in order to realize quantitative microsampling, on
It states and is provided with probe tube 200 in syringe 100,200 bottom opening 203 of probe tube is connect with needle tubing 201, i.e., probe tube 200 is direct
It is connected with needle tubing 201, and syringe 100 is not connected with needle tubing 201.200 open top 202 of probe tube and conducting in syringe 100,
Allow to by pulling piston 102 to be drawn into sample in probe tube 200 by needle tubing 201, in order to realize quantitative sampling, on
200 diameter of probe tube is stated to make to form cushion space 101, piston between probe tube 200 and syringe 100 less than 100 diameter of syringe
102 in up and down motion pipette samples to probe tube 200, it is empty to be stored in buffering along syringe 100 more than the liquid of 200 volume of probe tube
Between 101.Probe tube 200, which is made of the fixed spherical column of capacity so that observing, to be more prone to, using each spherical segment as one
A unit scales.Wherein, piston 102 is moved downward along syringe 100 until being abutted with 200 open top 202 of probe tube.
Above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to preferred embodiment pair
The utility model is described in detail, it will be understood by those of ordinary skill in the art that, it can be to the technology of the utility model
Scheme is modified or replaced equivalently, and without departing from the objective and range of technical solutions of the utility model, should all be covered
In the right of the utility model.
