Description

Technical Field

[0001] This utility model relates to the field of Bacillus cereus detection technology, specifically to a confirmatory experimental device for Bacillus cereus detection. Background Technology

[0002] In the detection of Bacillus cereus, confirmatory tests are necessary for the detected Bacillus cereus. Confirmatory tests are of great significance and necessity. They utilize various characteristic reactions, such as biochemical properties and serological reactions, to more accurately identify suspected Bacillus cereus from the initial screening. Furthermore, by utilizing the unique physiological and biochemical characteristics or genetic features of Bacillus cereus, it can be distinguished from other similar bacteria, avoiding misdiagnosis. Confirmatory tests significantly improve the reliability and accuracy of the detection results. Common confirmatory methods include Gram staining and spore observation. These methods share the characteristic of requiring repeated staining and drying of samples using multiple reagents. The repeated manual staining and drying of slides with staining agents is inconvenient and time-consuming, especially when handling large numbers of samples. Therefore, we propose... Utility Model Content

[0003] The purpose of this invention is to provide a confirmatory experimental device for detecting Bacillus cereus, so as to solve the problems mentioned in the background art.

[0004] A confirmatory experimental apparatus for detecting Bacillus cereus includes a transparent detection box. Two magnetic bases are symmetrically installed in the upper part of the transparent detection box. A glass slide is placed on the upper end of each magnetic base. Magnetic blocks are magnetically attracted to the upper ends of both sides of the glass slide, and the slide is fixed in place by the attraction between the magnetic blocks and the magnetic bases. Several syringes are provided at the upper part of the transparent detection box. The lower end of each syringe is connected to the upper end of a rigid long connecting tube made of metal or hard plastic via a connector. The lower end of the long connecting tube is inserted into the transparent detection box. Inside the transparent detection box, the lower ends of several long connecting tubes are positioned above the glass slide, ensuring that the liquid flowing from the long connecting tubes accurately acts on the glass slide. A horn head is also positioned directly above the glass slide, with its upper end connected to a gas guide tube. The upper end of the gas guide tube extends out of the transparent detection box and connects to the air bladder. A universal adapter is installed on the leftmost long connecting tube, allowing it a certain degree of rotation. The lower end of the transparent detection box is fitted over the liquid collection box, ensuring that all waste liquid can flow into the liquid collection box.

[0005] Preferably, the syringe connected to the leftmost long connecting tube has a larger capacity than the other syringes. The leftmost syringe is used to store disinfectant, and the surface of several syringes is provided with scale lines to facilitate control of the staining amount according to experimental needs.

[0006] Preferably, support blocks are symmetrically installed on both sides inside the liquid collection box, and a mesh plate is placed on the upper end of the support blocks. The mesh plate can prevent the alcohol lamp from being used for heating.

[0007] Preferably, the front end of the transparent testing box is equipped with an observation window, and opening and closing the observation window facilitates the placement and removal of glass slides.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] During the confirmation experiment, the various reagents, sterile water, disinfectant and other materials required for staining are first loaded into different syringes. After the bacterial strain to be confirmed is transferred onto the glass slide, the glass slide is placed on the upper end of two magnetic bases and fixed by magnetic blocks. Then, by pushing the syringe, the staining agent in the syringe drips onto the glass slide through the long connecting tube for staining. By squeezing the air bladder, an airflow is generated, which acts on the magnetic base through the air guide tube and the horn head to achieve air drying.

[0010] The entire confirmation experiment can be easily and quickly completed by a single person, and the amount of staining can be accurately controlled, making it easy to observe the staining effect. The entire process does not involve contact with reagents, and the waste liquid generated in the experiment is directly collected in the collection box, ensuring the safety and efficiency of the experiment and effectively improving the efficiency and effect of the experiment.

Two magnetic seats 2 are symmetrically installed in the upper part of the transparent detection box 1. A glass slide 3 is placed on the upper part of each magnetic seat 2. Magnetic blocks 4 are magnetically attracted to the upper sides of the glass slide 3, fixing the glass slide 3 in place by the attraction between the magnetic blocks 4 and the magnetic seats 2. Several syringes 5 are arranged in the upper part of the transparent detection box 1. The lower end of each syringe 5 is connected to the upper end of a rigid long connecting tube 7 via a connector 6. The long connecting tube 7 is made of metal or hard plastic. The lower end of the long connecting tube 7 is inserted into the transparent detection box 1, and the lower ends of several long connecting tubes 7 are all located above the glass slide 3, so that the liquid flowing from the long connecting tube 7 can accurately act on the glass slide. The syringe 5 connected to the leftmost long connecting tube 7 has a larger capacity than the other syringes 5. The syringe 5 is used to store disinfectant, and the surface of each syringe 5 is marked with graduation lines 15 to facilitate control of the staining amount according to experimental needs. A horn head 8 is also provided directly above the slide 3. The upper end of the horn head 8 is connected to the gas guide tube 9. The upper end of the gas guide tube 9 passes through the transparent detection box 1 and connects to the air bag 10. A universal adapter 11 is provided on the long connecting tube 7 located on the far left, so that the long connecting tube 7 has a certain degree of rotation freedom. The lower end of the transparent detection box 1 is fitted outside the liquid collection box 12 to ensure that all waste liquid can flow into the liquid collection box 12. Support blocks 13 are symmetrically installed on both sides inside the liquid collection box 12. A mesh plate 14 is placed on the upper end of the support block 13. The mesh plate 14 can prevent the alcohol lamp from being used for heating. An observation window 16 is installed at the front end of the transparent detection box 1. Opening and closing the observation window 16 facilitates the handling of the slide 3.

[0016] Working principle: During the confirmation experiment, various reagents, sterile water, disinfectant, etc. required for staining are first loaded into different syringes 5. After the bacteria to be confirmed are transferred onto the glass slide 3, the glass slide is placed on the upper end of the two magnetic seats 2 and fixed by the magnetic blocks 4. Then, by pushing the syringes 5, the staining agents in the different syringes 5 are dripped onto the glass slide 3 through the long connecting tube 7 according to the experimental steps. The air is generated by squeezing the air bag 10, and the air acts on the magnetic seat 2 through the air guide tube 9 and the horn head 8 to achieve air drying. Finally, the waste liquid generated by the experiment flows directly into the collection box 12 to ensure the safety and efficiency of the experiment.
