Description

Technical Field

[0001] This utility model relates to the field of culture medium technology, specifically to a culture device for improving the positive rate of Haemophilus influenzae detection. Background Technology

[0002] A search revealed that patent CN215250846U discloses a culture device for improving the positive rate of Haemophilus influenzae detection. In use, the culture medium is placed on the upper surface of the pad, and the knob is turned to make the clamping mechanism engage the culture medium. Substances that improve the positive rate of Haemophilus influenzae are added to the culture medium. When it is necessary to change the carbon dioxide concentration in the chamber, carbon dioxide gas is delivered through the air inlet pipe to improve the positive rate of Haemophilus influenzae.

[0003] When carbon dioxide gas is delivered into the chamber through the inlet pipe in the above-mentioned device, uneven distribution of carbon dioxide in the chamber can occur if the gas flow rate, delivery method, or air flow inside the chamber is uneven. This can result in localized excessively high or low carbon dioxide concentrations, which can affect the culture effect of Haemophilus influenzae. Therefore, a culture device that can improve the positive detection rate of Haemophilus influenzae is needed. Utility Model Content

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] In existing devices, when carbon dioxide gas is introduced into the chamber through the inlet pipe, uneven gas flow rate, delivery method, or airflow within the chamber can lead to uneven carbon dioxide distribution, resulting in locally excessively high or low carbon dioxide concentrations. This negatively impacts the cultivation of Haemophilus influenzae. Please refer to [link to relevant documentation]. Figures 1-4 This embodiment provides a culture device for improving the positive rate of Haemophilus influenzae detection, including a box 1 and a culture medium 2 disposed in the box 1. Two mounting blocks are symmetrically fixed on both sides of the culture medium 2, and two mounting slots are symmetrically opened on the inner side of the box 1. The two mounting blocks are fixed to the two mounting slots and can be separated, which facilitates the assembly and disassembly of the culture medium 2 in the box 1.

[0022] refer to Figures 3-4As shown, the stability of carbon dioxide concentration is crucial during the cultivation of Haemophilus influenzae, as it significantly impacts bacterial growth and metabolism. To ensure uniform carbon dioxide gas distribution, the following configuration is implemented: a flow guiding mechanism 3 is installed at the top of the chamber 1. This mechanism includes a carbon dioxide gas tank 31 mounted at the top of the chamber 1 and an exhaust orifice plate 32 located inside the chamber 1. A flow conveying assembly 33 for conducting carbon dioxide gas is installed between the carbon dioxide gas tank 31 and the exhaust orifice plate 32. This assembly includes an exhaust pipe 331 fixedly connected to the bottom of the carbon dioxide gas tank 31. An electric valve 333 is installed on the outer wall of the exhaust pipe 331. The bottom end is fixedly connected to a diversion channel 332, and the bottom end of the diversion channel 332 is fixedly connected to a flexible tube 334. The flexible tube 334 is fixedly connected to the drain plate 32. A substance that increases the positive rate of Haemophilus influenzae is added to the culture medium 2. When it is necessary to change the carbon dioxide concentration in the chamber 1, the electric valve 333 is opened through the control panel 5, so that the carbon dioxide gas in the carbon dioxide gas tank 31 is discharged to the diversion channel 332 through the exhaust pipe 331, and then distributed to multiple flexible tubes 334 through the diversion channel 332 until the carbon dioxide gas flows into the chamber 1 through the drain plate 32. This process ensures that the carbon dioxide gas can enter the chamber 1 in a relatively uniform manner, providing the necessary stable environment for cultivation. The inner side of the housing 1 is provided with a flow guiding assembly 34 for driving the drain orifice plate 32 to swing. The flow guiding assembly 34 includes a swing rod 343 that rotates at one end of the drain orifice plate 32. The other end of the drain orifice plate 32 is provided with an auxiliary swing assembly for stabilizing its swing. The auxiliary swing assembly includes a columnar block 345 fixed to the end of the drain orifice plate 32 away from the swing rod 343. The inner side of the housing 1 is provided with a swing rail 346 for the columnar block 345 to slide. One side of the top of the swing rod 343 is rotatably connected to the inner side of the chamber 1. A connecting sleeve 344 is fitted on the outer wall of the swing rod 343. A rotating plate 342 is rotatably connected to one side of the connecting sleeve 344. A motor 341 is fixed to one side of the chamber 1. One end of the top of the rotating plate 342 is fixed to the output end of the motor 341. During the process of carbon dioxide gas entering the chamber 1, the motor 341 is started to drive the rotating plate 342 to rotate. Through the connecting sleeve 344, the swing rod 343 swings. This mechanism allows the drain plate 32 to adjust its angle with the movement of the swing rod 343, thereby helping the carbon dioxide gas to be evenly distributed on the top of the culture medium 2. The dynamic drainage perforated plate 32 effectively avoids the problem of local accumulation or uneven concentration of gas in the chamber 1. At the same time, since carbon dioxide gas can more evenly cover the surface of the culture medium 2, Haemophilus will be in a more stable environment during the culture process, thereby improving its positive rate and growth effect. The uniform distribution of carbon dioxide can promote the adaptation of Haemophilus to oxygen and carbon dioxide, thereby improving the stability and success rate of the culture. Through this design, not only can the technical problem of uneven carbon dioxide distribution be effectively solved, but also the environment inside the incubator can be more suitable for the growth of Haemophilus, thereby improving the reproducibility and success rate of the experiment.

[0023] refer to Figure 1 As shown, a gas detector 4 for detecting carbon dioxide concentration is installed on the inner top wall of the housing 1. A control panel 5 is installed on the side of the housing 1 adjacent to the motor 341. The electric valve 333 and the gas detector 4 are both electrically connected to the control panel 5. The installation of the gas detector 4 can effectively improve the reliability of carbon dioxide concentration detection. By detecting the carbon dioxide concentration inside the housing 1 through the gas detector 4, the system can accurately report changes in gas concentration. The electrical connection with the control panel 5 allows the data from the gas detector 4 to be transmitted to the control panel 5 in real time, thereby automatically adjusting the opening and closing of the electric valve 333 to ensure that the carbon dioxide concentration is within the set ideal range.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
