Description

an incubator

technical field

The utility model relates to the technical field of microorganism culture, in particular to an incubator.

Background technique

At present, most of the microbial incubators commonly used in clinical are CO2 constant temperature incubators, which are vertical boxes and the inner door is made of tempered glass. The inner chamber is placed with a stainless steel partition for supporting the culture, which can be easily moved and the height can be changed arbitrarily. A silicone rubber sealing ring is installed between the studio and the glass door, and the temperature control is generally 5-50 ℃, with temperature indication, CO2 concentration indication and other devices. The technology commonly used for sterilization in microbial incubators is UV lamp irradiation. For example, after opening the incubator, turn on the UV lamp in the room for irradiation, or install a UV lamp device inside the incubator for irradiation. Usually, the overall environment in an incubator cannot be separated and can only be used to cultivate microorganisms that grow and reproduce in a specific environment.

However, the prior art has the following defects: the sterilization range of ultraviolet and other irradiation is wide and rapid, and the treatment time is short. However, microorganisms such as spores, cysts and viruses are highly resistant to ultraviolet radiation and are not easily killed. However, ultraviolet irradiation sterilization has no continuous disinfection ability, there may be a problem of photoreactivation of microorganisms, and it is not easy to achieve uniform radiation in the entire processing space, which easily affects the cultivation of microorganisms. And an incubator can generally only be used to cultivate microorganisms that grow and reproduce in a specific environment. If you want to cultivate a variety of microorganisms that require different cultivation environments, you need to use multiple microbial incubators in combination. In addition, indicators such as temperature and CO2 concentration in the incubator cannot be automatically recorded, which is not conducive to the continuous quality control of the laboratory and the control of the microbial culture environment. In addition, the operator can only observe the growth and reproduction of the organisms after opening the incubator to take out the culture, and the door of the currently commonly used incubator is too large, and frequent opening and closing may easily cause pollution.

The piping system 8 includes a pipeline 81 for conveying sterile gas, a pipeline 82 for extracting gas in the incubator, a pipeline 83 for conveying carbon dioxide, and a pipeline for conveying oxygen. The pipeline 84 and the gas circulation control device 85, each of the compartments 4 is also equipped with an ultraviolet sterilization lamp 9, a camera 10 and a monitoring device 11, the switch 7, the pipeline system 8, the ultraviolet sterilization lamp 9, the camera 10 and the monitoring device 11 are respectively electrically connected with the controller.

Preferably, there are six compartments 4 . A handle ring 6 is installed on each of the inner box doors 5 . The ultraviolet sterilization lamp 9 and the camera 10 are installed on the top of the compartment 4 , and the monitoring device 11 is installed on the side wall of the compartment 4 . Gas filter screens 12 are installed in the pipelines for conveying sterilizing gas 81 , extracting gas in the incubator 82 , conveying carbon dioxide 83 and conveying oxygen 84 , respectively. Each of the compartments 4 is provided with a storage board 13 .

The utility model is realized in this way, the incubator includes a box body 1 and an outer box door 2, the outer box door 2 is located at the front end of the box body 1 (as shown in Figure 1), and the side surface of the box body 1 is movably sealed with the outer box door 2 connect. The environment in the incubator is divided into 6 independent compartments 4 by the thermal insulation board layer 3. The thermal insulation board layer 3 can use double-layer vacuum insulation glass, but it is not limited to the use of this material. Replace it with other materials that are insulated and can form a closed space without affecting the cultivation of microorganisms. One side of the inner box door 5 is movably connected to the box body 1, and the inner box door 5 on the compartment 4 of each independent area can be opened and closed through the handle ring 6, without affecting other independent areas. Each area can be used to cultivate different microorganisms, with clear fixed partitions.

Each compartment 4 is equipped with an ultraviolet sterilization lamp 9, a camera 10 and monitoring equipment 11 for various indicators in the incubator. The monitoring device 11 can monitor the temperature, carbon dioxide concentration, oxygen concentration, gas pressure and other indicators in each compartment 4 . In addition, each compartment 4 is equipped with a storage board 13 for placing petri dishes or other objects, and the storage board 13 and the heat insulation board layer 3 at the bottom of the compartment 4 can be kept at a certain distance, and the distance can be based on the actual situation.

After the gas has been fumigated for a sufficient time, the gas pipe 82 in the incubator is drawn out and connected to an air extraction device (not shown) to empty the gas in the incubator, so as to ensure that the subsequent microbial culture will not be affected. Afterwards, the ultraviolet sterilization lamp 9 can be turned on by the switch 7 for irradiation. Two disinfection and sterilization technologies, fumigation and ultraviolet irradiation, are used to ensure that subsequent microbial cultures will not be contaminated.
