Description
Technical field
The utility model relates to microbe sampling apparatus field, is specially a kind of disposable lower fluid multifunctional microbial sampling thief.
Background technology
At present, the known method of sampling has three kinds:
1, form respectively cooperative mode by sampling tube, sampling swab, nutrient solution and culture dish; This kind of mode is because the experiment relating to is more, the time is long, it is loaded down with trivial details to operate and will have a large amount of professionals' participations., the sampling swab with microorganism is easily polluted in the process of transferring to sampling tube meanwhile, caused the inaccurate of sampling sample.
2, will sample, the mode of hold function " two-in-one "; This kind of mode relative mode 1 improves, and facilitated the preservation of sampling sample, but tool do not inoculated function.
" three the are combined into one " mode of 3, sampling tube, sampling swab, upper fluid mode combinations being worked together; This kind of mode is to be optimized in the enterprising step of above-mentioned two kinds of modes, to avoid the pollution in sampling and transmittance process, also increased upper fluid and dripped inoculation function.But it in the end cultivates inoculation link inherent defect, sampling tube need be inverted, and is seeded to culture dish or the microorganism culturing scraps of paper from upper liquid discharge device, this link also likely can cause to be polluted or causes microbial death, finally affects the quality of sampling sample.
Summary of the invention
The purpose of this utility model is, a kind of multifunctional microbial sampling apparatus that the various functions such as sampling, preservation, transhipment, inoculation are integrated in one is provided.This device is by complicated job simplification, procedure, rapid.
In order to achieve the above object, the utility model is achieved in that
Disposable lower fluid multifunctional microbial sampling thief, it comprises sampling tube chamber, sampling wiper bar and top block, bottom block; Described sampling tube top of chamber opening, closed bottom but be provided with through hole; Sampling wiper bar bottom is provided with swab head, and top is connected with top block, and described top block seals socket connection with the opening of sampling official jargon; Described bottom block comprises the pipe connecting of block body and block body outside top, the through hole UNICOM of described pipe connecting and sampling tube chamber bottom, block body bottom opening, inner hollow, on its inner roof wall, be vertically provided with circular platform type antiseepage plug, fractureing after pipe connecting, block body can be oppositely by bottom opening and with the socket connection of sampling tube chamber sealed bottom, the intrinsic truncated cone-shaped antiseepage plug of blocking a shot can insert in sampling tube chamber bottom through-hole and by its shutoff.
Described disposable lower fluid multifunctional microbial sampling thief, for ease of liquid sample, also comprise with sampling wiper bar and replace the pipette of use and the elastic cavity of bottom opening, described pipette both ends open, Tao You top, body of rod top block, the bottom opening of top end opening place and elastic cavity is tightly connected.
Described disposable lower fluid multifunctional microbial sampling thief, has liquid adding hole for adding nutrient solution on the upper end sidewall of top block, and has sealer that its capping is avoided polluting.
Described disposable lower fluid multifunctional microbial sampling thief, sampling tube chamber is provided with scale, is convenient in use control the capacity that drips liquid.
The utility model can complete the work such as sampling, preservation, transhipment, inoculation simultaneously, and can avoid well the pollution in sampling, preservation, transhipment, seeded process.
Accompanying drawing explanation
Fig. 1 is the first stereographic map of the present utility model.
Fig. 2 is the second stereographic map of the present utility model.
Embodiment
Further illustrate the utility model by specific embodiment below.
As shown in Figure 1 and Figure 2, a kind of disposable lower fluid multifunctional microbial sampling thief, it comprises sampling tube chamber 1, sampling wiper bar 4 and top block 2, bottom block 3; Described sampling tube chamber 1 open top, closed bottom but be provided with through hole; Sampling wiper bar 4 bottoms are provided with swab head, and top is connected with top block 2, and described top block 2 seals socket connection with the opening of sampling official jargon 1; Described bottom block comprises the pipe connecting of block body 3 and block body 3 outside top, the through hole UNICOM of described pipe connecting and sampling tube chamber 1 bottom, block body 3 bottom openings, inner hollow, on its inner roof wall, be vertically provided with circular platform type antiseepage plug 5, fractureing after pipe connecting, block body 3 can be oppositely by bottom opening and with the 1 sealed bottom socket connection of sampling tube chamber, the truncated cone-shaped antiseepage plug 5 in block body 3 can insert in sampling tube chamber 1 bottom through-hole and by its shutoff.
Described disposable lower fluid multifunctional microbial sampling thief, for ease of liquid sample, also comprise with sampling wiper bar 4 and replace the pipette of use and the elastic cavity of bottom opening, described pipette both ends open, Tao You top, body of rod top block, the bottom opening of top end opening place and elastic cavity is tightly connected.
Described disposable lower fluid multifunctional microbial sampling thief, has liquid adding hole for adding nutrient solution on the upper end sidewall of top block 2, and has sealer that its capping is avoided polluting.
Described disposable lower fluid multifunctional microbial sampling thief, sampling tube chamber 1 is provided with scale 6, is convenient in use control the capacity that drips liquid.
The disposable lower fluid multifunctional microbial sampler structure of the utility model is simple, easy to operate, and universal performance is good, and safety performance is good, can one man operation.Its suitable sampling of doing different test items, different accuracy, can effectively raise the efficiency, and saves time.In the time that needs are sampled, first sampling wiper bar is extracted, directly with swab head contact sampling sample; Collect after microorganism sample, sampling wiper bar is inserted in sampling tube chamber, swab head immerses in nutrient solution.In the time that experiment is cultivated, break disconnected lower pipe connecting, even if extruding sampling tube chamber liquid flows out by sampling tube chamber bottom through-hole, while dripping inoculation, first part nutrient solution is extruded, washed away through hole, avoid through hole to pollute, then drip on testing plate or substratum by required amount of solution.Inoculate complete, will block a shot body oppositely with the socket connection of sampling tube chamber sealed bottom, thereby the intrinsic truncated cone-shaped antiseepage plug of blocking a shot inserts in sampling tube chamber bottom through-hole and its shutoff remaining nutrient chemical liquid in tube chamber that prevents from sampling is oozed out.When liquid sample, extruding pipette apex cavity, produces negative pressure and sucks sample liquid, and then straight cutting enters to sample in tube chamber, discharges sample liquid, the airtight laboratory culture of taking back.So, the utility model can complete the work such as sampling, preservation, transhipment, inoculation simultaneously, and can avoid well the pollution in sampling, preservation, transhipment, seeded process.
