Intelligent sampling and transporting equipment for viral culture medium

Abstract

The invention relates to a virus culture medium transferring device. The virus culture medium transferring device comprises a box body, a virus storage tube, a culture medium reservoir, a detergent reservoir, a waste liquor reservoir, an automatic sample introduction device, a sensor system, an automatic control device, a pumping system and a sampler, wherein the sampler is located in an accommodating structure of the external wall of the box body, the virus storage tube is located inside the box body and is arranged around the automatic sample introduction device, and the automatic sample introduction device is connected with the culture medium reservoir, the detergent reservoir and the waste liquor reservoir through pipelines and is provided with the pumping system. According to the virus culture medium transferring device, automatic sampling, automatic collecting and no splashing during opening can be achieved, and thus, the virus culture medium transferring device has the characteristics of miniaturization, automation and integration.

Description

technical field [0001] The invention belongs to the field of biological equipment, and in particular relates to an intelligent sampling transport equipment for virus culture medium. Background technique [0002] Culture medium transportation equipment belongs to the miniaturized equipment commonly used in the biological field. It is used to transport biological culture medium. Since the transportation process has certain requirements for temperature, stability, safety, miniaturization, and integration, it is also Taking into account the function of sampling and transportation, it is generally used for sampling viruses, bacteria and other pathogens and putting them into the culture medium for transportation. There are also certain requirements for transportation time. Therefore, the miniaturized integrated culture medium transfer device is an important equipment in the field. Culture medium transfer equipment has been disclosed to varying degrees in the prior art, for example...

AI Technical Summary

Problems solved by technology

[0003] However, the equipment provided by the above-mentioned prior art documents has certain defects. The first is that the swab is soaked in the culture medium together with the rod and the sampling head of the swab after sampling. Since the rod of the swab contacts the air during the sampling process, the During the transportation process, the medium is always in contact with the medium and it is easy to cause bacterial contamination, resulting in a decrease in the accuracy of the test. When using the swab directly in the medium and agitating it, discard it, and then cover it with a sealed cover, which will increase the growth rate of the test. Second, the virus sample has a certain risk. The sealing structure adopted at the opening of the delivery device in the prior art generally adopts threaded connection or sealing plug. Due to the position of the transportation tool during transportation, Changes, causing the medium to come into contact with the threaded position or the sealing plug, which will easily cause liquid splashing when it is opened, and may cause biohazards; thirdly, a transfer device can generally only transport one sample, and a sampling tube is used to accommodate swabs , and to prevent liquid splashing when opening, the proportion of the volume of the culture medium in the sampling tube is very small, generally less than 1 / 5, and because the swab needs to be hand-held when using it, it is impossible to design the size too much for the convenience of sampling Small, because it is inconvenient to hold and sample, especially throat swabs, in order to extend into the pharynx, the swabs need to be designed with a larger size, generally at least greater than 10cm, in order to accommodate swabs of this size into the sampling tube, sampling The tube can only be designed with a larger size, such as greater than 10cm, and the actual transported pathogens and culture medium only occupy a small part of the overall space, resulting in most of the waste of space, making the volume of the transport device larger; and in the prior art The integrated automation degree of the conveying device is relatively low, and it does not have the functions of disinfection, cleaning, rinsing, stirring, etc.

Moreover, the culture medium with virus samples is easily affected by the ambient temperature during the transportation process. The transfer devices in the prior art are generally transported at room temperature, or put into an ice box, and the mouth of the nozzle is easily polluted when the ice melts.
