Description

A kind of modern times pasture milk sampler
Technical field
The invention belongs to body fluid sampling device technical fields, and in particular to a kind of modern times pasture milk sampler.
Background technology
It is a kind of mode of novel animal husbandry large-scale cultivation to modernize pasture, and the intensive of livestock is realized by modern facilities Change cultivation, feeding feed and forage grass, realization mechanization slaughter and milks in colony house by penkeeping.This breeding way Resource utilization is high, and the output capacity of the products such as milk meat is also higher, can meet the growing food demand of people.
The defects of this modernization pasture also has its own, due to intensive breeding way, causes the disease of livestock Infection rate is higher, and is susceptible to explosion type epidemic disease disaster.It needs to use high amount of drug and antibiotic in livestock farm management.
In the dairy cow farm of some modernizations, in order to resist the epidemic disease of livestock, cattle farm needs periodically to do for livestock Physical examination, and the detection of disease or medicament residue is carried out to the milk of extrusion, milk sampling needs to carry out sample using sampler This acquisition and preservation.Conventional suction pipe test tube sample mode is very convenient, and cost is relatively low, but comes down in torrents with higher sample Pollution or rotten risk, sample infection can be solved the problems, such as and go bad by being sampled using vacuum test tube and carrying out cold chain guarantor, but It is this vacuum test tube for disposable instrument, sampling cost is higher.
Invention content
For the defects in the prior art, the object of the present invention is to provide a kind of modern pasture milk sampler, this takes The advantages of sample utensil has sampling process simple, may be reused, and sampling cost is relatively low, and sample collection and preservation process are not Can occur sample contamination and it is rotten the problem of.
The technical scheme is that:A kind of modern times pasture milk sampler, including barostat with connect air pressure The suction pipe of adjuster, suction pipe include the insulating tube of outer layer and the liquid storage pipe of internal layer;Insulating tube is the bimetallic tube containing vacuum interlayer, The incubation cavity of closing between insulating tube and liquid storage pipe is set, cool storage medium is filled in incubation cavity;The liquid storage pipe includes top Sample chamber and lower section spiral capillary syring, gradually taper up below sample chamber and connect with capillary syring upper end, capillary suction Pipe lower end also connects metal suction nozzle, and metal suction nozzle is fixedly connected with insulating tube;The air cavity of the barostat and sample chamber Top connects, the connecting portion setting semi-transparency type diaphragm of the two.
On the basis of the present invention, barostat selects rubber ball cover, can using rubber sleave as barostat To reduce the production cost of sampler, and have the advantages that operation and control mode is simple.
More preferably technical solution is the another kind of barostat:Barostat includes cylindrical shape tracheae, is set on tracheae The pressing tablet to match with nozzle and lumen size is put, pressing tablet sets rubber seal with tube wall contact surface, and pressing tablet passes through Elastic rod is connect with tracheae bottom, and tracheae bottom setting through-hole is connected with sample chamber, and the link position of tracheae and sample chamber is also set Put semi-transparency type diaphragm.Pressing tablet is pressed during use, then discharges pressing tablet, due to the effect of elastic rod, pressing tablet is bounced, Milk sample is inhaled into sample chamber by air cavity in order to restore air pressure.The design of this barostat can be carried out preferably Air pressure adjustment, and the number reused, also much larger than rubber ball cover, and the safety of material is also better than rubber sleave, into The possibility that the reduction of one step pollutes the property of sample.
Preferably, the insulating tube is fabricated by transparent resin material;Capillary syring and liquid storage pipe are transparent by the resistance to temperature difference Glass manufacture forms;Cool storage medium is transparent or translucent.By transparent or semi-transparency type diaphragm material selection, sampled The sample size of journey can be observed directly, and due to the distinctive color of milk, sample can be allowed to be easier to be observed.This Outside, the insulating tube of outer layer can improve the impact resistance of sampler using resin material, prevent sampler in use It ruptures or breaks into pieces.Metal suction nozzle design below capillary syring is also for shockproof, the impact resistance for improving sampler.
It is further preferred that the heat preservation pipe outer wall position setting containing mark line corresponding with sample chamber.Graduation mark Setting can allow the capacity of sample collection that can be quantized, convenient for sample collection personnel operate.
The use process and principle of the sampler be:Before sampling, sampler is placed in refrigerator freezes first by acquisition person It preserves, after the cool storage medium in incubation cavity stores enough colds, acquisition person takes out sampler for sample collection.During sampling, The metal suction nozzle of sampler is placed on milk sample liquid level hereinafter, by pressing barostat and discharging, by milk by acquisition person Sample is drawn into sample chamber, and sample moves quickly through one section of spiral capillary syring before sample chamber is entered, since cold-storage is situated between The effect of matter, sample is cooled down rapidly, after the completion of sample collection, due to the continuous action of cool storage medium, and the portion in capillary syring Sample is divided to be frozen so that sample is sealed in sample chamber, will not be revealed from sampler, wherein between air cavity and sample chamber Semi-transparency type diaphragm can prevent acquisition sample enter air cavity, sampler or sample is caused to be contaminated in itself.Sample collection is complete It is sent in household freezer and is preserved after, while cool storage medium can ensure the full stage cold storage effect in flow, further Ensure the pure and healthy of sample;Sampler need to only be thawed during pattern detection.
A kind of modern pasture milk sampler provided by the invention, compared with prior art, has the advantages that:
The sampler can keep the whole cold storage effect of sampling, prevent sample sharp in sampling process mesometamorphism, and after sampling Sample exit port is freezed by the refrigeration of capillary syring with cool storage medium, sample chamber is sealed, is prevented in sample chamber Sample leakage is infected by other substances, and capillary syring can also promote cool storage medium to make the cooling of sample in sampling process With.
The sampler may be reused, and reduces the cost of livestock farm management side's single sampling, has greatly economic valency Value.Suction pipe, suction nozzle and the barostat of sampler are employed with the material compared with high-impact energy, are further improved and are taken The service life of sample device.
In addition, the sample chamber of the sampler, insulating tube and cool storage medium be using transparent or translucent material, outside insulating tube Be also provided with containing mark, allow sampling process can be more intuitive be observed and measure.
