Abstract

The utility model relates to a culture dish for the bacterial medicinal sensitive experiment. The utility model made of a plastic comprises a culture dish and a cover. The utility model is characterized in that seven small circles are evenly distributed on the bottom of the culture dish, and the positions for pasting medicinal sensitive paper sheets are marked out. Three graduated scales can pass through the center in the cover of the culture dish, and the graduation line of each graduated scale is projected out of an inner plane of the cover to reach 1 mm. Gaps exist between the cover and the culture dish wall after covering the cover, which is good for the air circulation of the inner part and the outer part of the culture dish. Three stepped plates are respectively and evenly distributed on the culture dish and the wall of the cover. Then, the cover is rotated to the stepped plates after covering the cover so as to carry out the pairwise crossing operation. At the time, the graduated scales are just positioned right above the medicinal sensitive paper sheet, which is good for measuring the size of each medicinal sensitive circle.

Description

Bacterial susceptibility experiment culture dish

Affiliated technical field

The utility model provides a kind of culture dish of bacterial susceptibility experiment usefulness.

Background technology

At present, the culture dish of the known experiment of bacterial susceptibility clinically usefulness is generally discoid, and the two sides is smooth, without any mark.The bottom does not have mark, causes the position of the scraps of paper when pasting drug sensitive test paper and distance each other to be not easy to determine, causes the drug sensitive test paper number pasted less, between each scraps of paper apart from the length inequality, influence the result of susceptibility.Do not have graduated scale above the lid, be unfavorable for reading of drug allergy ring size.Coincideing between lid and the culture dish is not tight, and lid rocks easily or comes off.

Summary of the invention

In order to overcome the deficiency of existing bacterial susceptibility experiment with culture dish, the utility model provides a kind of new culture dish (material is plastics), comprises culture dish and lid two portions.7 small circles that distributing equably in culture dish bottom have been indicated the position that drug sensitive test paper is pasted.The wall of the lid wall outside inboard and culture dish has 3 trapezoidal plates respectively, makes lid and culture dish tight connecting.Through the center of circle 3 graduated scales are arranged on the lid of culture dish, help the mensuration of drug allergy ring size.Simultaneously, the scale marks of graduated scale protrudes in the internal surface of lid, and making between the wall of lid and culture dish has some slits, has guaranteed the circulation of culture dish inner air and outer air.

The technical scheme that its technical problem that solves the utility model adopts is: it is to be made by plastic material, and is transparent, discoid, comprises culture dish and lid two portions.Culture dish is discoid, inside diameter 90mm, and the high 10mm of wall, the thickness of wall are 1mm.There is a circle (exceeding bottom surface 1mm) of protuberance a little in central authorities in disk bottom, and diameter 5mm is uniform-distribution with 6 same circles around it, and the distance between each circle center of circle is 30mm.These circles are the paste position of drug sensitive test paper.The lid of culture dish also is a disc, inside diameter 96mm, the high 8mm of wall, the thickness 1mm of wall.In lid inside, there are 3 graduated scales at the center of process disk, and the angle between each graduated scale is 60 degree.Center with disk is a starting point, indicates scale marks to periphery, minimum scale 1mm.Scale marks swells a little, and the about 1mm of inner plane of outstanding cap top to such an extent as to behind the cover lid, some slits are arranged between the end face of culture dish wall and lid, helps the circulation of culture dish inner air and outer air.At the intersection of lid internal calibration chi and cap walls a trapezoidal plate (long limit 3mm, high 2mm, minor face 2mm, thick 1mm) is arranged, its graduated scale adhesion high and cap top, the wall adhesion of long limit and lid is also vertical with the end face of lid.Equally the end at the two other graduated scale also has identical trapezoidal plate respectively, and three blocks of plates are at the inboard uniform distribution of cap walls.There are three circles in the center of circle through the culture dish bottom surface point-blank, also there is a trapezoidal plate upper end in the straight line one end culture dish wall outside, its shape is identical with trapezoidal plate on the lid, the wall adhesion of its long limit and culture dish, height is vertical with the wall of culture dish, and stretches out with the top of culture dish wall is concordant.Equally, identical trapezoidal plate is also arranged, three plate uniform distribution at other two collinear, one end.Behind the cover lid, the rotation lid, when the trapezoidal plate on the lid and the trapezoidal plate on the culture dish meet, at this moment the graduated scale on the lid just bottom culture dish three circles directly over, can read the drug allergy ring size easily and accurately.And, to make its actual outside diameter be 96mm (the trapezoidal plate hight 2mm of internal diameter 90mm+ wall thickness 1mm * 2+ * 2) in the existence of three trapezoidal plates on the culture dish wall, and lid and culture dish are better coincide, and lid is difficult for rocking or coming off, the long only 2mm of the minor face of while trapezoidal plate, lid can be opened easily.

The beneficial effects of the utility model are: the bottom of culture dish is uniform-distribution with 7 circles, has marked the position that drug sensitive test paper is pasted, and helps the convenient and reasonable stickup of drug sensitive test paper.Culture dish is made by plastics, and is transparent, helps the observation and the measurement of drug allergy ring.The existence of culture dish and cap walls upper trapezoid plate better coincide lid and culture dish, and lid is difficult for rocking or coming off.Cover lid also rotates to trapezoidal plate and intersects in twos, and three graduated scales on the lid directly over seven circles in culture dish bottom, can read the drug allergy ring size just easily and accurately.And scale marks protrudes in the inner plane of cap top, and making has some slits between culture dish and the lid, helps the circulation of culture dish inner air and outer air.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the oblique drawing of culture dish.Fig. 2 is the oblique drawing of culture dish lid.

Fig. 3 is the oblique drawing of culture dish behind the cover lid.

Fig. 4 is 5 times of enlarged views of culture dish and its cap walls upper trapezoid plate

Among Fig. 1, culture dish bottom internal diameter (1) 90mm, the high 10mm of wall (2), the thickness of wall is 1mm. On the bottom surface through three There is straight line in the center of circle of individual circle, has three straight lines, on the wall of straight line one end top a trapezoidal plate (3) is arranged, Three trapezoidal plates (3) evenly distribute in the periphery of wall, and the actual outside diameter that makes culture dish is 96mm. In the culture dish bottom surface There is the circle (4) of a projection centre, and circle exceeds bottom surface 1mm, and diameter 5mm is uniform-distribution with 6 together around it The circle of sample, the distance between each circle and the adjacent circles center of circle is 30mm.

Among Fig. 2, the internal diameter of lid (5) 96mm, the high 8mm of wall (6), the thickness 1mm of wall is in lid inside, through the top The central distribution of face 3 rules (7), and the angle between each rule is 60 degree.
