Self-sterilizing type microbial bacterial culture propagation inoculating instrument

Abstract

The invention belongs to the technical field of microbial culture and specifically relates to a self-sterilizing type microbial bacterial culture propagation inoculating instrument which comprises a shell body, an inoculating rod, a rotary module, a sterilizing module and a power supply module, wherein a notch is arranged at one end of the shell body, the inoculating rod is arranged in the notch in a rotary mode, the two ends of the inoculating rods can be used for inoculating, and the inoculating rod can be rotated through the rotary module to switch different ends to inoculate; the rotary module comprises a rotating shaft, a ratchet wheel, a pressing rod, a pawl and a reset spring; the sterilizing module comprises a positive pole contact switch, a positive pole binding post, a negative pole contact switch, a negative pole binding post and a heating wire; the power supply module is matched with the sterilizing module and can provide electric energy for the sterilizing module; the inoculating rod can be rotated through the rotary module to switch the different ends to inoculate; the end rotating into the shell body of the inoculating rod can be communicated with a circuit, and thepower supply module is utilized to heat the sterilizing module to achieve bacterial killing. The self-sterilizing type microbial bacterial culture propagation inoculating instrument disclosed by the invention has the advantages that varieties of bacterial inoculation can be performed, further residual bacteria can be killed in real time and experiment efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of microorganism cultivation, in particular to a self-sterilizing type microorganism bacteria cultivation and propagation inoculation instrument. Background technique [0002] At present, in the analysis experiments on microorganisms such as clinical bacterial analysis, it is necessary to inoculate the bacterial liquid on the surface of the petri dish, and then use observation and analysis equipment to conduct scientific experiments on it. [0003] Microbial inoculums are essential tools for microbiological research. But, there are two kinds at present, and a kind of is inoculating loop: existing inoculating loop comprises three parts of nickel-chromium wire, metal handle, insulating handle, and a screw port is arranged on the nickel-chromium wire; Another kind is glass spatula (being called again Coating rod), whether it is glass material or metal material, is a triangular coating rod, including a triangul...

AI Technical Summary

Problems solved by technology

The existing inoculation loops and coating rods for inoculation have the following disadvantages: after inoculation, new inoculation tools need to be replaced to prevent cross-contamination, and one tool cannot be used for multiple inoculations, and its efficiency is low; It is necessary to kill the residual bacteria from the previous inoculation, and additional sterilization operations are required, which affects work efficiency
