Embodiment

Consult Fig. 1, the utility model sample collecting device, for gathering the samples such as ight soil that clinical examination uses, blood, fester, gastric juice.Sample collecting device comprises sampler 10, sample tube 20, liquid-holding pipe 30, filtration members 40 and end cap 50.

Sampler 10 comprises inhales ball 11, thief rod 12, the first coupling arrangement 13 and the second coupling arrangement 14.The first coupling arrangement 13 and the second coupling arrangement 14 are arranged at respectively the two ends of inhaling ball 11.

See also Fig. 2, the first coupling arrangement 13 connects sample tube 20, inhales ball 11 and thief rod 12.Specifically, the first coupling arrangement 13 comprises the fixing screw thread installing port 133 of inhaling installation portion 131, the demarcation strip 132 of ball 11 and being connected sample tube 20.Installation portion 131 and screw thread installing port 133 lay respectively at the two ends of main part of the hollow of the first coupling arrangement 13.Demarcation strip 132 is arranged in main part to separate installation portion 131 and screw thread installing port 133, and the central position of demarcation strip 132 arranges mounting hole (not indicating).

Thief rod 12 is hollow structure, is connected to the mounting hole place of demarcation strip 132.In practical application, thief rod 12 can one-body moldedly also interconnect after moulding respectively with demarcation strip 132 again.Inhale the hollow cystic structures of ball 11 for being made by flexible glue or flexible plastic, therefore, inhale ball 11 and form with thief rod 12 hollow structure being interconnected, when needs collected specimens, ball 11 is inhaled in extruding, and sample can be inhaled in thief rod 12, makes the acquired volume of sample controlled.Further, the end arranged outside of thief rod 12 has sample picking portion 120.The sample that sample picking portion 120 is large for picking concentration, inconvenience is drawn.In the present embodiment, sample picking portion 120 is the protuberance that comprises one group of cone dentation or thorn-like, and the length of sample picking portion 120 is approximately 1 centimetre, and the length of protuberance is no more than 3 millimeters.

Sample tube 20 is the first tubular structure of an end opening, and its openend is connected with the first coupling arrangement 13.The diameter of the openend of sample tube 20 mates with the diameter of screw thread installing port 133.Corresponding to the screw thread installing port 133 of the first coupling arrangement 13, the openend of sample tube 20 is provided with screw thread docking section (not indicating).In screw thread installing port 133 and screw thread docking section, larger one of diameter arranges internal thread, and another arranges external thread.The openend of sample tube 20 and the first coupling arrangement 13 are threaded by screw thread docking section and screw thread installing port 133, with sealing thief rod 12 before sampler 10 samplings or after sampling.

The second coupling arrangement 14 connects inhales ball 11 and liquid-holding pipe 30.Liquid-holding pipe 30 is the second tubular structure of an end opening, for holding sample diluting liquid.The blind end of liquid-holding pipe 30 is fixedly connected with the second coupling arrangement 14.The blind end of liquid-holding pipe 30 is provided with cock 301, to allow the sample diluting liquid in liquid-holding pipe 30 to flow into sample tube 20 through inhaling ball 11 when cock 301 is opened, and allows the sample after dilution to flow out from the openend of liquid-holding pipe 30 through inhaling ball 11.

In the present embodiment, cock 301 is the first snap bar.The first snap bar forms first fold fracture after fractureing, and the sample diluting liquid in liquid-holding pipe 30 flows into and inhales ball 11 through first fold fracture, and the sample diluting liquid of inhaling in ball 11 flows into liquid-holding pipe 30 through first fold fracture.

Thief rod 12 is the second snap bar.Before the first snap bar of liquid-holding pipe 30 does not fracture, sample collection cartridge is set to an absorption structure with suction nozzle, in when sampling, and according to the physical aspect of sample, can picking, take or draw sample.The second snap bar forms the second fracture after fractureing, and the sample diluting liquid of inhaling in ball 11 flows into sample hose 20 through the second fracture, and the sample diluting liquid in sample hose 20 flows into and inhales ball 11 through the second fracture.

The diameter of the openend of liquid-holding pipe 30 is less than the diameter of the blind end of liquid-holding pipe 30, at the first snap bar, fractures and forms first fold fracture and the second snap bar and fracture and form after the second fracture, and the sample after being inhaled ball 11 and made to dilute by extruding oozes from openend.For the ease of fractureing of the first snap bar and the second snap bar, liquid-holding pipe 30 and sample tube 20 are elastic deformation part.

Please with reference to Fig. 2 to Fig. 4, end cap 50 is threaded with the openend of liquid-holding pipe 30, with the openend of shutoff liquid-holding pipe 30.Particularly, the internal diameter of end cap 50 mates with the external diameter of liquid-holding pipe 30, on end cap 50, internal thread is set, and the external thread mating with the internal thread of end cap 50 is set on liquid-holding pipe 30.

Filtration members 40 is arranged in the first coupling arrangement 13 or the second coupling arrangement 14, to filter the impurity in sample, avoids impurity to flow in liquid-holding pipe 30.

Below, take the sample collection of ight soil as example is to the collecting sample of the utility model sample collecting device with sample is carried out to preprocess method describe.

Sampling process is as follows:

First, before personnel's defecation of sampling, at the clean paper in urinal stand, will just come on paper.

Next, sample tube 20 is taken off from sampler 10, and according to the physical aspect sampling of ight soil.When concentration is larger, preferentially adopt sample picking portion 120 picking samples.Concentration hour, preferentially adopts thief rod 12 to draw samples.

Then, sample tube 20 is screwed to sampler 10, censorship.

After sampling, preprocessing process is as follows:

First, ball 11 is inhaled in extruding, and the sample in thief rod is blown and beaten out.

Next, fracture the first snap bar and the second snap bar, flow in sample tube 20 sample diluting liquid in liquid-holding pipe 30, and concuss sample collecting device, is fully dissolved in sample diluting liquid sample.

Then,, take off end cap 50 by liquid-holding pipe 30 down, ball 11 is inhaled in extruding can ooze ight soil solution to carry out microscopy or chemical examination work.

Be different from prior art, the thief rod 12 of the sampler 10 of the utility model sample collecting device and suction ball 11 form the hollow structure being interconnected, by extruding, inhaling ball 11 sucks sample in thief rod 12, can avoid gathering too much sample, the acquired volume of good Quality control, because the volume of sampling is controlled, therefore can directly to sample, dissolve, and without sample is carried out double sampling and affects environmental health.

These are only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model instructions and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
