Description

A smoke exposure model experimental device Technical Field

[0001] The invention belongs to the technical field of experimental devices, and in particular relates to a smoke exposure model experimental device. Background Art

[0002] The rise in the use of electronic nicotine delivery systems (ENDS), or e-cigarettes, is believed to increase the risk of addiction, particularly among adolescents. Understanding and assessing the behavior of ENDS-related addictive mouse models is fundamental to studying the neuropsychiatric effects of e-cigarettes. However, little is known about the behavioral characteristics of mice during e-cigarette exposure. Current assessments of addictive behavior rely on nicotine withdrawal-induced anxiety, which can only be assessed after ENDS exposure. Traditional behavioral assays, such as reward-based place preference and anxiety-based behavior after smoke withdrawal, include open field tests and elevated cross tests. The corresponding smoke test apparatus is shown in Figures 13-15. These behavioral assays are complex, time-consuming, and labor-intensive. They are also inconvenient for tracking mouse trajectories and cannot effectively monitor detailed behavioral characteristics of mice.

[0003] Based on this, the present application provides a smoke exposure model experimental device, which is equipped with an air intake mechanism in the exposure slot, and can simultaneously conduct smoke exposure experiments under the same conditions in different smoke chambers, making it convenient to track the behavior trajectory of the experimental subject, and at the same time, the fine behavior of the experimental subject can be observed through the camera.

DETAILED DESCRIPTION

[0038] The smoke exposure model experimental device shown in Figure 1-12 includes an exposure tank 1, an air intake mechanism 2, a smoke generator 3 and a camera 4.

[0039] The exposure tank 1 is cylindrical and is divided into eight smoke chambers 101 of equal size and shape by partitions 102. The cross-section of each smoke chamber 101 is fan-shaped. An air intake mechanism 2 is fixedly connected to the middle of the exposure tank 1. The air intake mechanism 2 includes a main body 201 and an air nozzle 202, which is fixedly connected to the top of the main body 201. The main body 201 is cylindrical and has a partition 207 inside, which divides the interior of the main body 201 into two cavities. The main body 201 has eight air inlets 203 evenly distributed on the top and eight air outlets 204 evenly distributed on the bottom. There is also a smoke exhaust hole 206, which is connected to each air outlet 204 through a cavity. Each air outlet 204 is connected to a smoke chamber 101. The air nozzle 202 has a smoke inlet hole 205, which is connected to each air inlet 203 through another cavity. Each air inlet 203 is connected to a smoke chamber 101. Four cameras 4 are provided above the exposure tank 1 , and the cameras 4 are used to record the behavioral changes of the experimental subjects under different smoke exposure conditions.

[0040] The smoke generator 3 includes an electronic cigarette 301, a fixing member 302, and a housing 303. The electronic cigarette 301 is disposed within the housing 303 and fixedly connected to the fixing member 302. The smoke generator 3 is connected to the smoke inlet 205 of the air nozzle 202 of the air intake mechanism 2 via a tube 8, and is also connected to the pump 7 via the tube 8. After the smoke generator 3 generates the electronic cigarette 301 smoke, under the action of the pump 7, the smoke flows along the tube 8 to the air intake mechanism 2, then passes through the air nozzle 202 of the air intake mechanism 2 through the air inlet 203 and enters different smoke chambers 101, where it is dispersed. Finally, the smoke in different smoke chambers 101 is discharged through the bottom air outlet 204 and the smoke exhaust hole 206. Since the air intake mechanism 2 is located in the middle of the exposure slot 1, the smoke conditions provided in each smoke chamber 101 are the same.

[0041] The present invention further includes a control mechanism 5. The control mechanism 5 is electrically connected to the pump 7 and is used to control the on and off of the pump 7, thereby facilitating the regulation of experimental conditions such as the amount of smoke and the smoke exposure time. The pump 7 can be a local structure within the control mechanism 5, or it can be connected to the control mechanism 5 as an independent unit. In this embodiment, the pump 7 is electrically connected to the control mechanism 5 as an independent unit. The control mechanism 5 is also electrically connected to the smoke generator 3 and is used to control the suspension of the operation of the smoke generator 3 and adjust the amount of smoke generated. The control mechanism 5, the pump 7, and the smoke generator 3 work together to provide different smoke exposure conditions for the smoke chamber 101 in the exposure tank 1, providing conditions for observing and collecting the behavioral characteristics of the experimental subjects under different smoke conditions.

[0042] The control mechanism 5 also has an infrared sensing module, a WiFi wireless module and a Bluetooth module, which communicate with the mobile terminal or remote control through the infrared sensing module, WiFi wireless module and Bluetooth module. In this way, relevant operations of the pump 7 and the smoke generator 3 can be performed through the mobile terminal or remote control, thereby improving the convenience of use.

[0043] The device of the present invention also includes a main control unit 6, which is electrically connected to the camera 4. The main control unit 6 transmits the real-time behavior of the subject recorded by the camera 4 to the main control unit 6 for data processing, construction of a model, and correlation of the behavior with indicator results. Based on these indicator results, the behavioral characteristics of the subject and the activity status within a specific time period are analyzed, thereby determining the impact of different fumes on the subject's behavior. The smoke exposure model experimental device of the present invention can be used to screen for pleasant aerosol substances or smoking cessation drugs through smoke experiments.

[0044] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
