Laboratory culture of strains has become particularly important, and aseptic inoculation is particularly critical as the first step in cultivating laboratory culture strains. At present, aseptic inoculation is mostly done manually on the clean bench in the laboratory, and each person is equipped with a corresponding alcohol lamp, test tube and culture dish. In traditional inoculation, each person is equipped with an alcohol lamp, which results in high fuel consumption, low alcohol lamp utilization efficiency, or insufficient laboratory alcohol lamps. In addition, this situation will also cause problems such as insufficient workbenches and smaller operating areas.

[0029] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] Embodiment 1

[0031] In a typical implementation of the present invention, reference is made to Figure 1 As shown, a laboratory microorganism inoculation device includes a box body 1, a test tube support plate 5 and an alcohol lamp 3. The top of the box body 1 is open, and the alcohol lamp 3 is placed inside. One end of the test tube support plate 5 is clamped on the top of the left and right side plates of the box body 1, and the test tube support plate 5 and the side plate are slidingly detachable. The test tube support plate 5 is used to support the test tube.

[0032] like Figure 1 As shown, the box body 1 of this embodiment is a cubic structure with an open top. Figure 1Taking the perspective as an example, the box body 1 includes a bottom plate, a front side plate, a rear side plate, a left side plate, and a right side plate. The four side plates have the same height, but a portion of the top of the left side plate and the right side plate extends upward to form a fixing portion 2. The fixing portion 2 is a plate-like structure and is located above the opening of the box body 1.

[0033] The top of the rear side plate of the box body 1 is hinged to the cover plate 4, and an opening is provided on the cover plate 4, and the opening is preferably a circular hole, so that the flame of the alcohol lamp 3 is exposed. The width of the cover plate 4 is smaller than the width of the rear side plate, and the front end of the cover plate 4 can overlap the top of the front side plate.

[0034] A groove is provided at the center of the bottom plate of the box body 1, and the groove is used to limit the bottom of the alcohol lamp 3 to prevent the alcohol lamp 3 from sliding inside the box body and causing danger.

[0035] A slide groove 8 is vertically arranged on the inner side of the side plate of the box body 1, and the two sides of the test tube support plate 5 are used to cooperate with the slide groove 8. The slide groove 8 of this embodiment is arranged on both sides of the front side plate and the rear side plate, and the spacing between the two slide grooves 8 on the same side of the front and rear side plates is adapted to the width of the test tube support plate 5. When the inoculation device needs to be stored, the test tube support plate can be vertically clamped inside the box body through the slide groove 8. It should be noted that the structure of the slide groove 8 is specifically a long strip groove structure, the purpose of which is to clamp and slide with the side of the test tube support plate 5.

[0036] The entire vaccination device is transformed into a box body 1 structure, which is convenient for storage and storage, occupies a small volume, and can be used in an integrated manner. Next time when vaccination is needed, the box body 1 can be directly opened and the corresponding structure can be assembled.

[0037] like Figure 1 As shown, the test tube support plate 5 is a plate-like structure, and two test tube clamping grooves 6 are provided on the top plate surface. The test tube clamping grooves 6 are used to clamp the test tubes to fix the test tubes and facilitate inoculation.

[0038] A clamping portion 7 is provided at the bottom of the front end of the test tube support plate 5. The clamping portion of the present embodiment is an inverted U-shaped structure, so as to be clamped with the fixed portion of the plate-like structure. When inoculation is required, the test tube support plate 5 is taken out of the box, the clamping portion 7 and the fixed portion 2 are aligned, the clamping portion 7 and the fixed portion 2 are clamped and slidably matched, and the test tube support plate 5 is slid to realize the clamping connection between the clamping portion 7 and the fixed portion 2.

[0039] Through the sliding cooperation between the clamping part 7 and the fixing part 2, the relative position of the test tube support plate 5 and the box body 1 can be easily adjusted, so that the vaccinee can make adjustments according to the vaccination habits.

[0040] It should be noted that the width of the test tube support plate 5 is smaller than the width of the side plate of the box, and the length of the clamping portion 7 is smaller than the length of the fixing portion, so that the test tube support plate can be clamped in the slide groove 8 in the box when stored.

[0041] In order to better fix the test tube, a rubber material is provided inside the test tube clamping groove 6. The test tube clamping groove 6 extends on the plate surface of the test tube support plate 5 and is provided with two paths. The test tube clamping groove 6 extends to the front end of the test tube support plate 5, and the length of the test tube clamping groove 6 is less than the length of the test tube, so that the front end of the test tube extends out of the front end of the test tube support plate.

[0042] The two test tube clamping slots 6 of the present embodiment are distributed in an eight-shaped pattern on the test tube support plate, so that when test tubes are clamped in the two test tube clamping slots 6, the test tube openings of the two test tubes extend above the opening of the box body 1, so that the test tube openings can be located around the flame of the alcohol lamp, ensuring a sterile environment and improving the success rate of inoculation.

[0043] The clamping portion 7 of this embodiment is arranged at an acute angle to the surface of the test tube support plate 5, so that the test tube can be tilted toward the alcohol lamp. Compared with the vertical placement of the test tube in the prior art, this solution can ensure the sterile environment during inoculation to the greatest extent. During inoculation, the microorganisms in the first test tube are inoculated into the second test tube through a tool.

[0044] The box body 1 is supported by a transparent heat-insulating material, which is heat-resistant and prevents the vaccine recipient from being scalded. At the same time, the amount of alcohol used in the alcohol lamp can also be observed.

[0045] It should be noted that the test tube support plate 5 can be prefabricated in various types. The difference between different types of test tube support plates 5 is that the sizes of the test tube slots 6 are different so as to meet the standards of most test tubes on the market.

[0046] The test tube support plate 5 of this embodiment is slidably matched with the box body 1, which not only ensures the flexibility of the connection, but also facilitates its disassembly, so that two vaccinators can operate in a relatively comfortable position, reducing fatigue and discomfort caused by long-term operation. The vaccinators on both sides share an alcohol lamp, which improves the efficiency of alcohol use and effectively shortens the operation time.

[0047] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
