Technical Field

The utility model belongs to the technical field of experimental apparatus, concretely relates to novel bacterination ware.

Background

The inoculating loop is a commonly used inoculating tool in bacterial culture and is widely applied to the fields of various subjects such as microbial detection, cytomicrobiology, molecular biology and the like; the existing inoculator has a single structure, and needs to be sterilized for many times or replaced by a new inoculator in order to prevent cross contamination when an inoculating loop is used; the inoculation system needs cooling for use during multiple times of sterilization, so that more time is consumed, the inoculation efficiency is greatly reduced, and meanwhile, the risk that the inoculation system is not placed in a standard manner after disinfection, is easy to pollute or is not operated properly, so that the cooling time of an inoculation ring is not long enough, the target microorganisms die, and the inoculation test fails exists; when the disposable inoculator is replaced, the using amount of the disposable inoculator is greatly increased, so that the inoculation cost is increased, and the bacteria which can be scraped by the inoculating ring are fewer, so that the preparation requirement of high-concentration bacterial suspension cannot be met.

Disclosure of Invention

In order to overcome the defects that the prior inoculator in the background technology has simple structure, needs to be sterilized for multiple times when in use, has long cooling time consumption, low inoculation efficiency and recycling rate, is difficult to sterilize after use, is placed nonstandard after sterilization, is easy to pollute, often causes death of target microorganisms and the like, and causes test failure; in addition, the scraping amount of the bacteria of the inoculating loop is less, and the preparation requirement of high-concentration bacterial suspension cannot be met, the utility model provides a novel bacteria inoculator which is simple to operate and can ensure that the damage of a culture medium can be avoided when bacteria are subjected to streak culture; overall structure is single, and the volume is narrow and small, can accomplish the sterilization work of inoculation instrument in batches in advance, ensures that enough inoculation rifle head can be changed when the inoculation, can improve inoculation efficiency greatly. The groove design is convenient for scraping a large amount of bacterial thalli at one time, and a technical support is laid for rapidly preparing high-concentration bacterial suspension.

In order to achieve the above purpose, the utility model is realized by the following technical scheme: the utility model provides a novel bacterination ware is main includes inoculation rifle head, operating handle, the inoculation rifle head be the cone, the pointed end is equipped with the globular contact head that is used for the streak to cultivate, well lower part is offered and is used for scraping the recess of getting the thallus, the big head end of cone is equipped with the jack, operating handle one end can dismantle to insert and establish in the jack.

The inoculation gun head is integrally formed by polypropylene materials.

The novel inoculator further comprises a gun head box, wherein the gun head box comprises a box body, a supporting partition plate and a cover body, the supporting partition plate is provided with a frame capable of being embedded and installed with a box opening of the box body, the supporting partition plate is installed on the box body, and the cover body covers the supporting partition plate; the inoculation gun is characterized in that the supporting partition plate is evenly provided with placing holes, 2-4 supporting columns are evenly distributed at the large end of the inoculation gun head in the circumferential direction, the inoculation gun head is inserted into the placing holes and supported and limited by the supporting columns and the supporting partition plate, and the spherical contact head is in a suspended state.

The operating handle is provided with a finger groove which is convenient for holding and preventing the operating handle from rotating during scribing; the operating handle is provided with a notch which prevents the thalli at the local position from being not scraped due to the fact that the operating handle is too high in contact with the mouth of the culture dish when the thalli are scraped.

The utility model has the advantages that:

the utility model has simple operation, and can avoid the damage of the culture medium when the bacteria streak culture is carried out; overall structure is single, and the volume is narrow and small, can carry out the sterilization work of inoculation instrument in batches in advance, ensures that enough inoculation rifle head can be changed when the inoculation, has improved inoculation efficiency. The groove design is convenient for scraping a large amount of bacterial thalli at one time, and a technical support is laid for rapidly preparing high-concentration bacterial suspension; the cleaning can be repeatedly sterilized for use, and the inoculation cost is reduced.
