Abstract
The utility model provides an improved Behrman device of good stability, high sensitivity, short time consumption and low cost for checking nematode in the body of an animal or a person, which comprises a hob dais 5, a funnel 1 arranged on the hob dais 5, a flexible hose 2 connected with the bottom of the funnel 1, a tube 3 connected with the other side of the flexible hose 2, a tube clamp 4 arranged on the short tube 3 and a mesh screen 6 arranged in the funnel 1. The utility model has the advantages of being used to check parasite nematode larva in the fecal of the animals and human beings as well as finding nematode larva in any organs or tissues.
Description
(1) technical field
The utility model belongs to the checkout facility of a kind of parasitic disease in the biological field, specifically a kind of modified form Bel Man device that is used for checking the parasitic nematode larva in animal and human's ight soil or is used to find the nematode larval of any organ or tissue.
(2) background technology
Because the symptom of nematodiasis lacks specificity, therefore, only rely on clinical symptoms, be difficult to animal and human's nematodiasis is made sure diagnosis, so, need to depend on breadboard inspection to a large extent, with the laboratory examination method in the content of tested animal and human's excrement, urine, blood etc., seek worm's ovum, larva or polypide, and make correct diagnosis according to evaluation to the pathogen found.
Some parasitizes the nematode in animal and human's body, and the worm's ovum of its output has become larva in new ight soil of discharging, and as net filaria, former strongyle, quasi-colubriformis etc., therefore, can carry out the evaluation of worm kind according to the form of larva and make correct diagnosis.But, it is to excrete with the ight soil of worm's ovum form with the animal and human that the numerous species nematode is arranged, the size of these nematode worm's ovums and profile are all quite similar, thereby it is very difficult on the worm kind is differentiated, except some worm's ovum has obvious color or distinctive shape, most worm's ovum all is difficult to be classified.People had once done many effort for many years, had carried out a large amount of work, the form of various nematode worm's ovums is done contrast describe, and the size of worm's ovum is carried out detailed tolerance, but still can not make sure fully diagnosis to worm's ovum.Yet, the third phase larva of these nematodes, form has different separately features with structure, can according to the third phase larva morphological feature distinguished.In order to distinguish the kind of these nematodes, the ight soil that often will contain worm's ovum is cultivated, and when treating wherein worm's ovum bud into larva, reexamines larva, according to the modal difference of larva, and antidiastole in addition.
Method commonly used is Bel's Man method when searching these nematode larvals, when using the inspection of Bel's Man method, must use Bel's Man device.Employed in the past Bel's Man device is to be formed by connecting by simple glass funnel, hose, small test tube etc., because simple glass funnel (diameter 10cm) and small test tube (long 2cm) are little, the water and the fecal specimens amount of institute's splendid attire are few, nematode larval sinks in the simple glass funnel slowly, and then collected nematode larval quantity is also just few, therefore, can cause the larva recall rate low, sensitivity is poor, and the supervision time is long, occurs the situation of mistaken diagnosis easily.
(3) utility model content
Good stability when the purpose of this utility model is to provide nematode in a kind of animal and human's of inspection body, highly sensitive, the supervision time is short, cost is low modified form Bel Man device.
The purpose of this utility model is achieved in that test tube 3 that its funnel 1, end on comprising iron stand 5 and being arranged on iron stand 5 is connected the hose 2 of funnel 1 bottom, an end and connects hose 2 other ends, be installed in the test tube clamp 4 on the short test tube 3 and be arranged on mesh screen 6 in the funnel 1.
The utility model also has some architectural features like this:
1, described funnel 1 is a wineglass type glass funnel;
2, described funnel 1 is arranged on the clamping rings 7 of iron stand 5;
3, described mesh screen 6 is the circle brass wire cloth.
The utility model modified form Bel Man device adds warm water earlier in wineglass type glass funnel when using, and makes liquid level reach round brass wire cloth top slightly, discharges the bubble in wineglass type glass funnel neck and the proofed sleeve.Then, fresh excreta (or the organ or tissue of having smashed to pieces, soil, plant and feed) is placed on the interior round brass wire cloth of wineglass type glass funnel, floods till the ight soil.Leave standstill, this moment is because action of gravity and nematode larval have the hydrotropism, and the nematode larval migration and is sunken to short test tube bottom in water.Clamp the rubber part that short test tube is connected with hose with test tube clamp, flow out to prevent the liquid in the wineglass type glass funnel.Choosing is connected on short test tube under the hose, will lack invisible spectro supernatant liquid and incline to, and the precipitation of short test tube bottom is shaken up, all be poured on the microslide, perhaps pour in a little plate or the watch glass,, and calculate the nematode larval number of finding then at test under microscope.
The utility model can be used for checking the parasitic nematode larva in animal and human's ight soil, also can be used for finding the nematode larval in any organ or tissue, in addition, also is applicable to the nematode larval inspection of the free living in ocean, fresh water, soil, plant and the feed.Modified form Bel Man device of the present utility model is to be formed by connecting by wineglass type glass funnel, hose, short test tube etc., because wineglass type glass funnel (diameter 20cm) and short test tube (long 5cm) are big, the water and the fecal specimens amount of institute's splendid attire are big, nematode larval sinks in wineglass type glass funnel soon, and then collected nematode larval quantity is also just many, therefore, can improve recall rate and the sensitivity of larva, can shorten the supervision time, not be prone to the mistaken diagnosis situation.

Fig. 1 is the assembling synoptic diagram of the utility model modified form Bel Man device;
Fig. 2 is the vertical view of wineglass type glass funnel;
Fig. 3 is the side view of wineglass type glass funnel;
Fig. 4 is for being provided with the synoptic diagram of round brass wire cloth in the wineglass type glass funnel;
Fig. 5 is the side view of short test tube.
(5) embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
1, the accessory of the utility model modified form Bel Man device consists of:
(1) the wineglass type glass funnel of 20cm diameter is 1;
(2) hose of 20cm length is 1;
(3) the short test tube of 5cm length is 1;
(4) the round brass wire cloth of 15cm diameter is 1;
(5) common iron stand is 1;
(6) test tube clamp is 1.
2, assemble method is:
Get the long hose of 20cm, connect the wineglass type glass funnel of a 20cm diameter with the one end, the other end then connects the long short test tube of a 5cm, installs a test tube clamp on short test tube.Wineglass type glass funnel is put on the clamping rings of common iron stand, put into the round brass wire cloth of a 15cm diameter in the wineglass type glass funnel.
3, use principle and method are
Add warm water (about 40 ℃) earlier in wineglass type glass funnel, make liquid level reach round brass wire cloth top slightly, discharge the bubble in wineglass type glass funnel neck and the proofed sleeve.Then, the about 30～50g of fresh excreta (or the organ or tissue of having smashed to pieces, soil, plant and feed) is placed on the interior round brass wire cloth of wineglass type glass funnel, floods till the ight soil.Leave standstill 1～3h, this moment is because action of gravity and nematode larval have the hydrotropism, and the nematode larval migration and is sunken to short test tube bottom in water.Clamp the rubber part that short test tube is connected with hose with test tube clamp, flow out to prevent the liquid in the wineglass type glass funnel.Choosing is connected on short test tube under the hose, will lack invisible spectro supernatant liquid and incline to, and the precipitation of short test tube bottom is shaken up, all be poured on the microslide, perhaps pour in a little plate or the watch glass,, and calculate the nematode larval number of finding then at test under microscope.
