Description

Technical Field

[0001] The utility model relates to the technical field of culture medium inoculation, in particular to a microorganism culture medium inoculation device. Background Technique

[0002] A culture medium refers to a nutrient matrix prepared by combining different nutrients to supply the growth and reproduction of microorganisms, plants or animals (or tissues). Generally, it contains several major substances such as carbohydrates, nitrogen-containing substances, inorganic salts (including trace elements), vitamins and water. The culture medium is not only the basic substance that provides cell nutrition and promotes cell proliferation, but also the living environment for cell growth and reproduction. To pick bacteria from the culture and inoculate the culture medium, an inoculation loop and an inoculation needle are needed.

[0003] However, the currently used inoculation loops and inoculation needles are too slender, resulting in troublesome hand-held operation. Moreover, there are various specifications for inoculation loops and inoculation needles. For inoculating different culture media, it is necessary to repeatedly replace different inoculation loops and inoculation needles, resulting in relatively troublesome inoculation operations. Therefore, in view of this situation, a microorganism culture medium inoculation device is designed. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a microorganism culture medium inoculation device, which solves the problems put forward in the above background technique.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A microorganism culture medium inoculation device includes a handle. Four sliding cavities are opened inside the handle. A slider is slidably connected inside the sliding cavity. A chute is circumferentially opened on the handle. One side of the slider is connected to an operation block through a connecting block passing through the chute. A cover is buckled at one end of the handle. Four through holes are opened on the surface of the cover. An insertion soft block is arranged on the other side of the slider. Multiple inoculation needles and inoculation loops of different specifications are inserted inside the insertion soft block.

[0006] Optionally, anti-slip patterns for convenient picking and operation are arranged on the surfaces of the handle and the operation block.

[0007] Optionally, a protective cover is threadedly connected to the surface of one end of the handle.

[0008] Optionally, the size of the slider is adapted to the size of the sliding cavity, and a damping sleeve for increasing damping is arranged on the surface of the slider.

[0009] Optionally, the inner diameter of the through hole is adapted to the diameter of the insertion soft block.

[0010] The utility model provides a microorganism culture medium inoculation device, which has the following beneficial effects:

[0011] 1. The microbial culture medium inoculation device is provided with a handle and anti-slip patterns, which can facilitate the operator to hold and take the device for inoculation. Through the provision of a plurality of inoculation needles and inoculation loops of different specifications, it can facilitate the operator to inoculate different culture media, and flexibly and quickly replace the corresponding inoculation needles and inoculation loops. At the same time, through the settings of the slider, sliding groove, connecting block, and operating block in the sliding cavity, the elongation length of each inoculation needle and inoculation loop can be adjusted, and inoculation can be carried out flexibly, greatly facilitating the operator.

[0012] 2. The microbial culture medium inoculation device is provided with plug-in soft blocks to directly plug and install the inoculation needles and inoculation loops, which can facilitate the operator to replace damaged inoculation needles and inoculation loops. Through the provision of a protective cover, the inoculation needles and inoculation loops can be protected. Through the provision of a damping sleeve, the damping effect of the slider can be increased, effectively preventing the slider from being too flexible and causing the inoculation needles and inoculation loops to retract during inoculation.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a microbial culture medium inoculation device, including a handle 1. A protective cover 13 is threadedly connected to the surface of one end of the handle 1. Through the setting of the protective cover 13, the inoculation needle 10 and the inoculation loop 11 are protected. Four sliding cavities 2 are opened inside the handle 1. A slider 3 is slidably connected inside the sliding cavity 2. The size of the slider 3 is adapted to the size of the sliding cavity 2. In order to effectively prevent the slider 3 from being too flexible, resulting in the situation that the inoculation needle 10 and the inoculation loop 11 retract during inoculation, a damping sleeve 14 for increasing damping is provided on the surface of the slider 3, which can increase the damping effect when the slider 3 slides;

[0019] A chute 4 is circumferentially opened on the handle 1. One side of the slider 3 passes through the chute 4 through a connecting block 5 and is connected to an operating block 6. Through the setting of the slider 3, the chute 4, the connecting block 5, and the operating block 6 inside the sliding cavity 2, the elongation lengths of each inoculation needle 10 and inoculation loop 11 can be adjusted, and inoculation can be carried out flexibly, which greatly facilitates the operator. Anti-slip patterns 12 for convenient handling are provided on the surfaces of the handle 1 and the operating block 6. Through the setting of the handle 1 and the anti-slip patterns 12, the operator can conveniently hold the device to carry out inoculation. A sealing cover 7 is buckled at one end of the handle 1. Four through holes 8 are opened on the surface of the sealing cover 7. An insertion soft block 9 is provided on the other side of the slider 3. The inner diameter of the through hole 8 is adapted to the diameter of the insertion soft block 9. When the operating block 6 pushes the slider 3 to the front end, the insertion soft block 9 will expose from the through hole 8 to directly insert and install the inoculation needle 10 and the inoculation loop 11, which can facilitate the operator to replace and install the damaged inoculation needle 10 and inoculation loop 11. Multiple inoculation needles 10 and inoculation loops 11 of different specifications are inserted inside the insertion soft block 9. Through the setting of multiple inoculation needles 10 and inoculation loops 11 of different specifications, it is convenient for the operator to inoculate different culture media and flexibly and quickly replace the corresponding inoculation needle 10 and inoculation loop 11.

[0020] In the present utility model, the working steps of the device are as follows:

[0021] When in use, first open the protective cover 13, hold the handle 1 by hand, and according to different inoculation methods, select to push the corresponding operating block 6 forward to make one of the inoculation needles 10 or inoculation loops 11 extend forward;

[0022] Then burn the selected inoculation needle 10 or inoculation loop 11 on the alcohol lamp flame for sterilization, and then carry out the inoculation of the microbial culture medium.

[0023] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its utility model concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
