Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the use of the microbial mass spectrometry, bacteria are required to be picked and uniformly coated on round holes of a target plate of the microbial mass spectrometry, the diameter of the round holes is about 2.5mm-3mm, the diameters of bacterial colonies are usually different from 0.2mm to 6mm, the shapes, sizes and properties of different bacteria are greatly different, and thus a proper coating tool is required to pick and coat the bacteria. Due to the diversity and complexity of bacterial colonies, this part of the work can only be done manually at present. At present, manufacturers recommend to use an inoculating loop for coating, after coating is finished, target sites which are not ideal for coating need to be cleaned or recoated, only the whole target plate can be cleaned at present, if a single target site is wrongly coated, surrounding hole sites all need to be cleaned and recoated, no tool for finely cleaning the single-hole target site exists, the target site holes can be accurately processed by using the tool, other target sites are not influenced, and the target plate resources are saved.

Based on this, the utility model provides a clearance ware is used in preparation of microorganism mass spectrum target plate can thoroughly clear away the bacterial strain on the single target site on the target plate, and the cleaning efficiency is high, and is accurate good, does not influence other target sites, simple structure, and convenient to use can ensure the accuracy of testing result when follow-up use.

To facilitate understanding of the present embodiment, the following provides a detailed description of the cleaner for preparing a target plate of a microbial mass spectrometer disclosed in the present invention.

Example one

Referring to fig. 1, 2, 3 and 4, the present embodiment provides a cleaner for preparing a target plate of a microbial mass spectrometer, which comprises a seed collecting handle 1 and a cleaning head 2 detachably mounted on at least one end of the seed collecting handle 1, wherein a cleaning table 3 is arranged at the end of the cleaning head 2, and an adhesive layer 4 is arranged at the top end of the cleaning table 3 (as shown in fig. 4 and 6).

Specifically, the detachable connection of the inoculation handle 1 and the cleaning head 2 means that the cleaning head 2 can be clamped on the inoculation handle 1, can also be in threaded connection with the inoculation handle 1, and can also be detachably connected in other manners. The cleaning head 2 of this embodiment is hollow inside, and a fixing groove is provided therein to be detachably connected with the inoculation crown 11. The inoculation handle 1 is arranged to be reusable, and the cleaning head 2 is arranged to be disposable. As shown in FIG. 2, in this embodiment, the right end of the inoculation handle 1 is provided with a conical inoculation handle tip 11, the length of the inoculation handle 1 is 124.93mm, and the length of the inoculation handle tip 11 is 14.7 mm. The length of the cleaning head 2 is 42.81mm, the cleaning head 2 is sleeved on the inoculation handle head 11, and the diameter of the cleaning head 2 is 5.03 mm.
