[0028] Currently, when performing an eye instillation experiment on a mouse, the mouse often has a stress response.

[0030] The following further elaborates on the embodiments of the present utility model in conjunction with the drawings.

[0031] Referring to Figures 1 to 5 , the embodiment of the present utility model provides a mouse eye blowing device, including:

[0032] Fixing module 100, comprising a first electric push rod 110, a second electric push rod 120 and a receiving cavity. The movable end of the first electric push rod 110 is provided with a first fixing plate 130, and the movable end of the second electric push rod 120 is provided with a second fixing plate 140. The receiving cavity is used for placing a mouse 500. A third fixing plate 150 is fixed to the head of the mouse 500. The first electric push rod 110 and the second electric push rod 120 are respectively arranged on both sides of the third fixing plate 150. The first electric push rod 110 is used to push the first fixing plate 130 towards the third fixing plate 150, and the second electric push rod 120 is used to push the second fixing plate 140 towards the third fixing plate 150;

[0033] Blowing module 200, comprising a compressor 210 and a nozzle 220. The air outlet of the compressor 210 is communicated with the nozzle 220 through a pipeline, and the nozzle 220 faces the eyes of the mouse 500;

[0034] Control module 300, the fixing module 100 and the blowing module 200 are respectively electrically connected to the control module 300.

[0035] Based on this, the mouse 500 is placed in the receiving cavity. A third fixing plate 150 is fixed to the head of the mouse 500. A first electric push rod 110 and a second electric push rod 120 are arranged in the receiving cavity. The movable end of the first electric push rod 110 is provided with a first fixing plate 130, and the movable end of the second electric push rod 120 is provided with a second fixing plate 140. The first electric push rod 110 is used to push the first fixing plate 130 towards the third fixing plate 150, and the second electric push rod 120 is used to push the second fixing plate 140 towards the third fixing plate 150. The first fixing plate 130 and the second fixing plate 140 simultaneously abut against the third fixing plate 150 from both ends of the third fixing plate 150 to fix the third fixing plate 150, thereby fixing the head of the mouse 500; when blowing air to the eyes of the mouse 500 through the blowing module 200, the mouse 500 will have a stress reaction and flee. Therefore, before blowing air to the eyes of the mouse 500 through the blowing module 200, the first electric push rod 110 is used to push the first fixing plate 130 towards the third fixing plate 150, and the second electric push rod 120 is used to push towards the third fixing plate 150, so as to be able to fix the head of the mouse 500, avoid the mouse 500 shaking its head or even running around during the blowing process, and also avoid the fixing module 100 directly squeezing the head of the mouse 500, thereby ensuring that the blowing module 200 is always aligned with the eyes of the mouse 500 and ensuring the smooth completion of the blowing experiment.

[0036] In a specific embodiment, the compressor 210 is used to compress air or a stimulating gas, and blow the air or the stimulating gas towards the eyes of the mouse 500 through the nozzle 220.

[0037] In a specific embodiment, the accommodation chamber is a sealed space formed by splicing a plurality of one-way perspective glasses. An illuminating lamp is arranged in the accommodation chamber, and the illuminating lamp is electrically connected to the control module 300.

[0038] It can be understood that after the illuminating lamp in the accommodation chamber is turned on, the light intensity inside the accommodation chamber is greater than that outside the accommodation chamber. Therefore, the experimenter outside the accommodation chamber can observe the mouse 500 inside the accommodation chamber, which is beneficial for the experimenter to record the experimental process of the mouse 500. However, the mouse 500 inside the accommodation chamber cannot observe the vision outside the accommodation chamber, which can avoid the mouse 500 from being frightened, thereby ensuring the accuracy of the experimental results.

[0039] In a specific embodiment, the mouse eye blowing device further includes an exhaust gas treatment module. The exhaust gas treatment module is communicated with the accommodation chamber through a pipeline, and the exhaust gas treatment module is used to treat and discharge the gas in the container chamber.

[0040] Refer to Figure 4 , in some embodiments of the present invention, the blowing module 200 further includes a plurality of gas storage containers 230, and each of the gas storage containers 230 is respectively communicated with the air inlet of the compressor 210 through a pipeline.

[0041] In a specific embodiment, each of the gas storage containers 230 is used to store different types and concentrations of gases.

[0042] It can be understood that the gas storage containers 230 store air, irritating gases, germ-carrying gases or medicinal gases, so that the mouse eye blowing device can respectively conduct eye sensitivity experiments and pathological experiments on the mouse 500, thereby improving the versatility of the mouse eye blowing device.

[0043] Refer to again Figure 1 , in some embodiments of the present invention, a pressure sensor 270 is arranged inside each of the gas storage containers 230. The pressure sensor 270 is electrically connected to the control module 300, and the pressure sensor 270 is used to measure the gas pressure inside the gas storage container 230.

[0044] Specifically, the control module 300 obtains the gas pressure inside the gas storage container 230 through the pressure sensor 270. When the gas pressure is less than a preset pressure threshold, the control module 300 stops the operation of the compressor 210, wherein the pressure threshold is greater than the standard atmospheric pressure of air.

[0045] It can be understood that after the compressor 210 operates for a period of time, the gas pressure in the gas storage container 230 gradually decreases. When the gas pressure in the gas storage container 230 is less than the gas pressure in the accommodation cavity, when the compressor 210 operates, the gas in the container cavity will be sucked into the gas storage container 230, affecting the purity of the gas in the gas storage container 230. Therefore, by setting the air pressure sensor 270 to obtain the gas pressure in the gas storage container 230, and the control module 300 controls the working state of the compressor 210 through the gas pressure, it can prevent air from entering the gas storage container 230 through the compressor 210, thereby ensuring the accuracy of the experimental results.

[0046] In a specific embodiment, a concentration detector is also provided in the gas storage container 230. The control module 300 obtains the gas concentration in the gas storage container 230 through the concentration detector. When the gas concentration is less than the preset concentration threshold, the control module 300 stops the compressor 210 from operating, thereby being able to prevent the gas concentration from being too low and affecting the accuracy of the experimental results.

[0047] Refer again to Figure 1 and Figure 4 In some embodiments of the present utility model, each of the gas storage containers 230 is communicated with the compressor 210 through its corresponding first isolation valve 240, and each of the first isolation valves 240 is electrically connected to the control module 300.

[0048] It can be understood that the control module 300 is used to control the opening and closing of the first isolation valve 240, thereby controlling the conduction state between the compressor 210 and each gas storage container 230.

[0049] Based on this, by providing the first isolation valve 240 between each gas storage container 230 and the compressor 210, it can prevent the gases in each gas storage container 230 from mixing in the compressor 210.

[0050] Refer again to Figure 1 and Figure 4 In some embodiments of the present utility model, the blowing module 200 further includes a second isolation valve 250. The second isolation valve 250 is electrically connected to the control module 300, and the compressor 210, the second isolation valve 250, and the air nozzle 220 are sequentially communicated through pipelines.

[0051] In a specific embodiment, the blowing module 200 includes two air nozzles 220 and two second isolation valves 250. Each air nozzle 220 is respectively communicated with the compressor 210 through the corresponding second isolation valve 250. The second isolation valve 250 is used to control the conduction state between the compressor 210 and the corresponding air nozzle 220. One of the air nozzles 220 faces the left eye of the mouse 500, and the other air nozzle 220 faces the right eye of the mouse 500.

[0052] Based on this, by arranging a second isolation valve 250 between the compressor 210 and the air nozzle 220, the gas remaining in the compressor 210 can be timely prevented from flowing out of the air nozzle 220, and the flow states between the two air nozzles 220 and the compressor 210 can be separately controlled, so as to control the blowing module 200 to blow air to the left eye or the right eye separately.

[0053] Refer again to Figure 1 and Figure 4 As shown in, the blowing module 200 includes a pressure regulating valve 260 which is electrically connected to the control module 300. The compressor 210, the pressure regulating valve 260, the second isolation valve 250 and the air nozzle 220 are sequentially connected through pipelines. The pressure regulating valve 260 is used to control the flow rate of the gas in the blowing module 200.

[0054] In a specific embodiment, the blowing module 200 includes two pressure regulating valves 260. The compressor 210, the corresponding second isolation valve 250, the corresponding pressure regulating valve 260 and the corresponding air nozzle 220 are sequentially communicated through pipelines.

[0055] It can be understood that the pressure regulating valve 260 is used to control the flow rate of the gas flowing out of the corresponding air nozzle 220.

[0056] Refer to Figure 5 As shown in, in some embodiments of the present invention, the control module 300 includes a main control chip 310 and an operation panel 320. The operation panel 320 is electrically connected to the main control chip 310.

[0057] In a specific embodiment, the control module 300 is designed and developed by an Arduino development board. The operation panel 320 includes a start button, a pause button and a single-shot button. The start button is used to control the mouse eye blowing device to blow air according to a preset blowing script. When the single-shot button is pressed, the corresponding first isolation valve 240, second isolation valve 250 and pressure regulating valve 260 are turned on, and the compressor 210 starts. When the single-shot button is released, the corresponding first isolation valve 240, second isolation valve 250 and pressure regulating valve 260 are closed, and the compressor 210 shuts down.

[0058] Based on this, by arranging the operation panel 320 to control the working state of the mouse eye blowing device, the blowing efficiency of the mouse eye blowing device can be effectively improved. The main control chip 310 stores a preset blowing script. By pressing the start button, the mouse eye blowing device is controlled to blow air according to the preset blowing script, without the need for experimental personnel to operate, which can also improve the blowing efficiency of the mouse eye blowing device and avoid the influence of misoperation of experimental personnel on the accuracy of experimental results.

[0059] Refer toFigure 5 , in some embodiments of the present utility model, the control module 300 further includes a timer 330, and the timer 330 is electrically connected to the main control chip 310.

[0060] It can be understood that the main control chip 310 obtains the first duration of continuous blowing of the mouse eye blowing device through the timer 330 and the second duration of stopping blowing, and the control module 300 adjusts the working states of the blowing module 200 and the fixing module 100 according to the first duration and the second duration.

[0061] Refer again to Figure 5 , in some embodiments of the present utility model, the control module 300 further includes a relay 340. The main control chip 310 is connected to the control circuit of the relay 340, and the blowing module 200 and a high-voltage power supply (not shown in the figure) are respectively connected to both ends of the load circuit of the relay 340.

[0062] It can be understood that the main control chip 310 outputs a control signal with a small current to conduct the control circuit of the relay 340, so that the load circuit of the relay 340 is connected, the high-voltage power supply supplies power to the blowing module 200, and the blowing module 200 starts to operate.

[0063] Refer again to Figure 1 , in some embodiments of the present utility model, it further includes a display module 400, and the display module 400 is electrically connected to the control module 300.

[0064] Specifically, the display module 400 is used to display the working state of the blowing module 200, the working state of the fixing module 100, the gas pressure and gas concentration in each gas storage container 230, the working state of each first isolation valve 240, the working state of each second isolation valve 250, the gas flow rate, the first duration, and the second duration.

[0065] It can be understood that by setting the display module 400 to display the working states of the mouse eye blowing device, it is convenient for the experimenter to regulate the mouse eye blowing device and also convenient for the experimenter to record the experimental process of the blowing experiment.

[0066] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the knowledge scope of those of ordinary skill in the art.
