Background technique

At present, microbial inoculation is done by manual scribing. It is necessary to manually remove the sample tube and shake it, then manually cover it and scan the label. For the petri dish, manually remove the cover and stick the label manually after scribing. . Manual marking mainly has the following defects:

(1) Factors such as differences in individual levels, personal habits, and the randomness of the same person at different times lead to various lines drawn. There is no uniform standard, which affects the vaccination effect and increases the difficulty of doctors' judgment. In addition, environmental factors can also play a role.

(2) The operation efficiency is low, the labor cost is high, and the labor intensity is high.

(3) Operators must be very careful when working, otherwise germs may get on their hands or splash on their bodies, which will cause harm to human health.

The beneficial effects of the present invention are:

(1) Fully automatic completion of test tube shaking, cap removal, scanning, capping, petri dish automatic capping, automatic marking, automatic labeling and other operations, which improves work efficiency and reduces costs. Manual scribing generally processes 30 culture dishes in one hour, while the present invention processes 50-80 culture dishes in one hour.

(2) The accuracy of streaking inoculation is improved, and the interference caused by human factors is eliminated. The mechanical marking is completely the same standard, no matter when and who is operating it, the drawing is absolutely uniform.

(3) The present invention is a fully enclosed operation, and the operator only needs to touch the computer screen on the outside to complete the whole process, thus completely isolating the infection of germs and eliminating the risk of medical staff being infected with germs.

(4) Save labor costs. Usually, 2-4 people are needed in the microbiology room to carry out streak inoculation, but after adopting the present invention, these people can be completely liberated and operated by one person. At the same time, the labor intensity is reduced, and the operator even has time to do other work.

(5) The alarm and reminder functions make it unnecessary for special personnel to guard the device.
