Description

Multipurpose culture dish

Technical Field

The utility model belongs to the technical field of the medical supplies technique and specifically relates to a culture dish of multipurpose is related to.

Background

The bacterial culture can be divided into three types of ordinary aerobic culture, anaerobic culture and carbon dioxide culture. The latter two types need special culture boxes and corresponding canned gas supply, especially the anaerobic culture box needs to provide a mixed gas source for air replacement, and the cost is high and the operation is complex and the popularization rate is low for small and medium experiments. Many laboratories use anaerobic tanks and anaerobic bag methods. Anaerobic cultivation is performed by consuming oxygen in a closed culture tank or a sealed bag through an anaerobic bag to create an anaerobic environment. However, in the process of the method, oxygen outside the culture dish is consumed firstly, and then oxygen in the culture dish is consumed, so that the time for oxygen contact is longer for obligate anaerobic bacteria, the anaerobic bacteria are easy to die, and the culture survival rate is reduced. In addition, the method cannot increase the number of inoculated culture specimens midway, otherwise the anaerobic environment is destroyed, and an anaerobic gas generating bag must be put in again to create the anaerobic environment, so that the method is very inconvenient for daily work and has high culture cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a multipurpose culture dish.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a culture dish of multipurpose, includes one end open-ended ware body, and the opening part of the ware body is equipped with the ware lid, and the central point of ware lid is equipped with the chucking device that is used for pressing from both sides tight product gas pocket and oxygen indicator, and the chucking device is including being fixed in the fixed block of ware lid inner wall, and the fixed block internal rotation is connected with the fixation clamp, is equipped with the torsional spring between fixation clamp and the fixed block, and the both ends of torsional spring are fixed mutually with fixation clamp and fixed block respectively, and the ware body is sealed through rotatory chucking structure relatively fixed with the.

The fixation clamp comprises a supporting rod and two pressing rods, wherein the supporting rod is rotatably connected with the fixation block, the two pressing rods are mutually fixed with the supporting rod, and a certain distance is reserved between the two pressing rods.

The end of the pressure lever far away from the support rod is provided with a sawtooth which is arranged on one side of the pressure lever on the dish cover.

The rotary clamping structure comprises a flanging which is arranged at the opening of the dish body and extends outwards, a plurality of pressing blocks which are arranged on the end face of the dish cover and are sealed with the dish body and the flanging in corresponding positions and are arranged on the inner wall of the dish cover, notches which are corresponding to the pressing blocks in positions are arranged on the flanging, the width of each notch is larger than that of each pressing block, the lower ends of the pressing blocks are of arc structures, the arc structures are separated from the sealing pads by a certain distance and are used for containing the flanging, and the flanging is tightly attached to the sealing pads and the.

The utility model has the advantages that: the design can be directly used as a common culture dish in normal times, and can be used for multiple purposes culture by being matched with a small anaerobic gas generating bag, a micro-aerobic gas generating bag and a carbon dioxide gas generating bag. Taking anaerobic culture as an example, after an anaerobic gas generating bag is placed at the fixing clamp, the dish body and the dish cover are tightly rotated to form a closed space, so that the required anaerobic environment can be quickly formed in the culture dish for culturing anaerobic bacteria, and the consumption of the gas generating bag is only one tenth of that of a common anaerobic tank and an anaerobic bag method. The utility model discloses not only material saving and operation are very convenient, and fixed gas bag to rotatory chucking is airtight only need for ten seconds at most time, effectively reduces the anaerobe because expose for a long time and lead to the death of anaerobe in the aerobic environment, effectively improves the anaerobe survival rate. In addition, the cultured specimen can be sealed to prevent aerosol pollution and spore pollution of fungal aerial hyphae, and the biological safety in the experimental process can be improved.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 5, a multipurpose culture dish comprises a dish body 1 with an opening at one end, a configured anaerobic culture medium is placed in the dish body 1, during normal experiments, the opening of the dish body 1 is placed downwards, if the liquid in the culture is more, the opening of the dish body 1 is placed upwards, a dish cover 2 is arranged at the opening of the dish body 1, a clamping device 5 for clamping an air generating bag and an oxygen indicator is arranged at the central part of the dish cover 2, the air generating bag can be an anaerobic air generating bag, a microaerobic air generating bag or a carbon dioxide air generating bag according to the requirements of the cultivation, the clamping device 5 comprises a fixed block 51 fixed on the inner wall of the dish cover 2, a fixed clamp 52 is rotationally connected to the fixed block 51, the fixed clamp 52 comprises a supporting rod 55 rotationally connected to the fixed block 51 and two pressing rods 56 mutually fixed to the supporting rod 55, a certain distance is arranged between the two pressing rods 56, the middle parts of the pressing rods 56 are slightly bent to, the clamping is more reliable, the sawtooth 53 is arranged at one end, far away from the support rod 55, of the pressure rod 56, the sawtooth 53 is arranged at one side, located on the dish cover 2, of the pressure rod 56, and the sawtooth 53 can be used for increasing the friction force between the pressure rod 56 and the gas generating bag, so that the gas generating bag is more firmly fixed; the fixture may also hold an oxygen indicator to visually detect the gaseous environment within the culture dish.
