Description

A kind of culture dish for drug sensitive test measurement inhibition zone radius

Technical field

The utility model relates to experimental apparatus technical fields, more particularly to one kind to measure inhibition zone radius for drug sensitive test Culture dish.

Background technique

Culture dish is a kind of to be often used during drug sensitive test for microorganism or the labware of cell culture Culture dish carries out the measurement of bacterial drug susceptibility, needs to measure the size of inhibition zone during the test, to feed back bacterium Susceptibility.The culture dish of existing measurement inhibition zone size is broadly divided into two classes: one kind is that the setting of Measurement scales line exists On the bottom wall of culture dish, the size of transparent inhibition zone is read from front；Second class is that setting measurement is carved in the ware lid of culture dish Line is spent, the size of inhibition zone is read.There are the following problems for the culture dish of these two types measurement inhibition zone size: 1, when in culture dish Bacterium base fluid band color or it is opaque when, the graduation mark being arranged on culture dish bottom wall can not be read；2, it is arranged in ware lid Graduation mark, can be because read when being read using the graduation mark in ware lid due to too long apart from bacterium base fluid surface distance apart from too long Inhibition zone radius is taken to generate error；3, it when drug sensitive test, needs to select different cultures according to different bacterium base fluids Ware needs to prepare a plurality of types of culture dishes in laboratory, is unfavorable for the management of laboratory；4, the graduation mark being arranged on culture dish It is easy be corroded, scratch in the process of cleaning, influences the service life of culture dish.

Utility model content

In order to solve the above-mentioned technical problem the utility model provides that a kind of structure is simple, can measure inhibition zone radius and energy Enough batches carry out the culture dish of drug sensitive test, to solve at least one of above-mentioned technical problem.

The technical solution that the utility model solves above-mentioned technical problem is as follows:

A kind of culture dish for drug sensitive test measurement inhibition zone radius, comprising: transparent ware disk, the ware disk are cylinder Shape structure, and ware disk upper end is equipped with opening, further includes a transparent ware seat, the periphery of the ware seat, which is equipped with, to be upwardly extended Annular seat wall, the ware disk is located on the ware seat, and the seat wall is sheathed on the outside of the ware disk, the ware disk The inner wall of outer wall and the seat wall is slidably connected；

The inner bottom wall of the ware seat is equipped with a transparent measurement plate, and the ware seat is fixed in the lower surface of the measurement plate In inner bottom wall, the upper surface of the measurement plate is abutted with the bottom wall of the ware disk.

The beneficial effects of the utility model are: ware seat can be respectively sleeved at the upper and lower ends of ware disk, culture can be measured Inhibition zone size in ware can play the supporting role to ware disk when the bottom of ware disk is arranged in, while measurement plate is accurate The upper wall for being fitted in ware seat and ware disk bottom wall between, the inhibition zone size that when such measurement plate use measures is more accurate.

Based on the above technical solution, the utility model can also do following improvement.

Further, the ware seat is equipped with the groove of the annular extended downwardly, the bottom wall edge ring in the outside of the ware disk To the support protrusion cooperated with the groove is equipped with, the support protrusion is set in the groove.

Beneficial effect using above-mentioned further scheme is: when not using ware seat, the support protrusion of ware pan bottom can be with It plays a supporting role to ware disk；When ware seating is when ware disk upper end, the groove inside ware seat can accommodate the support protrusion of ware disk, It avoids ware disk and ware seat time due to existing support protrusion, and so that measurement plate and ware is tried to get to the heart of a matter between wall and be spaced and make measurement result There is error.

Further, the inner wall of the seat wall extends downward into the bottom of the groove, and the circumferential inner sidewall of the groove Diameter be less than the ware disk on the upside of opening diameter.

Beneficial effect using above-mentioned further scheme is: such groove can be such that ware seat uses as ware lid, ware disk Open edge slid into groove by the inner wall of seat wall, the top of ware dish opening is abutted with the bottom wall of groove, can be made in this way Culture solution in the closer ware disk of measurement plate, can also read the inhibition zone size in ware disk in this way, can be adapted for training in this way It is used in the case that nutrient solution is opaque, improves the use scope of ware disk.

Further, the bottom wall of the ware seat is equipped with the stomata for the bottom wall to be connected.

Beneficial effect using above-mentioned further scheme is: stomata can prevent between ware seat and ware disk slide when both it Between form closed cavity, influence the use of culture dish, be arranged after stomata more convenient when can slide.

Further, the measurement plate is equipped with well shape scale and cross scale, the well shape scale and cross scale Center be overlapped and be located at the ware disk central axis on.

Beneficial effect using above-mentioned further scheme is: well shape scale and cross scale can be respectively used to having a competition It tests and single test, when carrying out susceptibility research and development test using culture dish, it is more accurate to be measured using cross scale；Work as progress When comparative test, the size of single inhibition zone can be quickly measured using scale is carried out.

Further, it is equipped with label A at the center of the cross scale, sets on the well shape scale there are four marking B, four A circumferentially spaced-apart outside for being set to the label A the label B.

Beneficial effect using above-mentioned further scheme is: label A and label B can be convenient for the position of cachet pharmaceutical, just It is carried out in drug sensitive test.
