Abstract

The utility model relates to a micro-organism sensitive drug screening case. The center of a culturing disk is provided with a filtering disk, filtering objects are arranged in the filtering disk, a plurality of culturing small sections are divided between the outside diameter of the filtering disk and the inner diameter of an outer circle of the culturing disk, a point of each culturing small section corresponding to the middle upper part of the outside diameter of the filtering disk is provided with a liquid overflow hole, the point of the culturing small section near the outside diameter of the culturing disk is provided with a drug containing tube, the drug containing tube corresponding to the culturing disk is provided with an upper cover, and the cover surface of the upper cover is carved with a plurality of circles of scale marks. By using the utility model, the conformity of the composition, the thickness and the culturing detection condition of a culture medium of each test sample can be ensured, the detection error can be reduction, and micro-organism sensitive drugs can be conveniently, rapidly and accurately screened.

Description

Microorganism sensitive medicaments screening box

The utility model belongs to the improvement of microorganism sensitive medicaments triage techniques.

At present the microorganism sensitive medicaments triage techniques that uses is earlier with test equipment high-temperature sterilizations such as culture dish, filtration units, after more various culture medium raw materials being configured, dissolves through heating, regulates pH value, filter and divide install in the culture dish stand-by.When doing shaker test, the microbiological specimens for preparing is spread upon media surface, treat to put into the filter paper that contains medicine after the surface drying.After cultivating the some time under certain conditions, measure the size that various medicines suppress the formed inhibition loop diameter of microorganism growth, the action effect of more various medicines.The shortcoming of this technology is:

1. in preparation work, need certain device condition, operative technique and time;

2. the substratum prolonged preservation needs the certain device condition;

3. can only fill a kind of substratum in each culture dish;

4. a culture dish (90 millimeters of diameters) generally can only be done 6 drug samples;

5. the medicine filter paper needs to preserve separately, puts into when to be tested again;

6. test-results needs to measure with ruler.

China is that biological species is cultured big country, plants the breed biology and is infested with all diseases.And general production unit is limit because of the technology and equipment condition, is difficult to therefore the Drug abuse phenomenon often occur on producing by the selected effectively preventing medicine of drug sensitive test in case disease occurs.So both cause the disease preventing and treating effect undesirable, polluted environment again.Particularly in the preventing and controlling of bacteriosis,, make pathogenic bacteria resistance occur, influenced prevention effect because the abuse of antibiotics phenomenon is very general.

The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, provides a kind of and can simplify screening conditions, reduces waste of material and shortens screening time, guarantees The selection result microorganism sensitive medicaments screening accurately box.

The technical solution of the utility model is finished like this: this microorganism sensitive medicaments screening box is made up of culture plate, loam cake, there is a filtering table in its culture plate central authorities, be provided with filtrate in the filtering table, be separated into several between filtering table external diameter and the culture plate cylindrical internal diameter and cultivate the zonule, each cultivates the zonule and corresponding position, filtering table external diameter middle and upper part has a liquid spill-way, cultivating the zonule goes out to have one to contain pencil by the culture plate external diameter, with culture plate to a loam cake should be arranged, be carved with some circle scale markss on the capping of loam cake, culture plate and loam cake can be airtight become an integral body.The utlity model has following advantage:

1. culture plate, substratum, filtration unit, the loam cake treating screening of medicaments and have a scale marks are assembled in the integral body, and culture plate and loam cake all adopt transparent material to make, therefore can directly read The selection result.

2. select medicine box simple in structure, use easy to carryly, (as plant) manipulates directly at the scene.Can reduce the loaded down with trivial details of screening operation in the use and overcome condition restriction, save screening time.

3. one is selected can place in the medicine box and cultivates screening conditions according to different microorganisms and different pharmaceutical and require the multiple substratum prepared.

4. one is selected medicine box (90 millimeters of diameters) can be separated into the cultivation zonule more than 20, and promptly one is selected medicine box just can the medicine more than 20 kinds to be screened simultaneously, saves test materials, guarantees that screening conditions are consistent between each sample, reduces and detects error.

5. select medicine box after the sealing sterilization, can under general condition preserve the long period.

Fig. 1 is the utility model culture plate front view.

Fig. 2 is the utility model superstructure synoptic diagram.

Fig. 3 is that Fig. 1 K is to the rotation enlarged view.

Among the figure: 1 filtering table, 2 dividing plates, 4 culture plates, 5 loam cakes, 6 scale markss, 7 filters, 8 cultivate

The zonule, 9 contain pencil, 10 liquid spill-ways

Now further describe embodiment in conjunction with drawing: this microorganism sensitive medicaments screening box is made up of culture plate, loam cake, there is an awl bar shape filtering table in its culture plate central authorities, the filtering table inwall has a netted filtering sheet that fits, be separated into several by dividing plate between filtering table external diameter and the culture plate cylindrical internal diameter and cultivate the zonule, each is cultivated in the zonule and fills substratum, and cultivating the zonule has one to contain pencil by the culture plate outer radius.Filtering table outer wall middle and upper part has a liquid spill-way on each cultivates the cultivation basal plane of zonule direction, corresponding with culture plate have a loam cake, is carved with some circle scale markss on the capping of loam cake, and culture plate and loam cake can be airtight become an integral body.

Filtering table in the culture plate also can adopt cylindrical shape or six bar shapes.

The filter that the filtering table inwall fits also can adopt the stronger filter paper of penetrating power, sponge, cotton, diatomite etc.

Liquid spill-way can be an aperture or the breach in the filtering table outer wall.

When using this to select medicine box, use earlier through the disinfectant instrument and take off testing sample (as lesion tissue), sample added pour (liquid sample can directly be poured filtering table into) in the filtering table after physiological saline is suitably smashed to pieces into, the liquid that has microorganism flows into the media surface that each cultivates the zonule by liquid spill-way after filtering, rock culture plate gently and make liquid be covered with whole media surface equably, take out filtrate and filtration residue again.Fill in the filtering table with the sterilization cotton after 1-2 minute, take out cotton after the excess liquid to adsorb in each cultivation zonule and the filtering table.Culture plate is tight with loam cake lid, sealing, cultivate the some time under certain conditions after, observe detected result.Because the screening box is a transparence, needs only the production area that just can directly compare microorganism by the scale marks of loam cake, filters out suitable antimicrobial agents with this.
