Description

Technical Field

[0001] This invention relates to the field of experimental device technology, specifically to an experimental chamber that simulates damage to rats caused by a hot and dry desert environment. Background Technology

[0002] Research on injured rats is now common, and collecting data on repair processes and glycan excretion during the recovery process is of great medical significance. However, due to environmental factors, injured rats need to be placed in a hot and dry desert environment for observation. Currently, when creating a rat model of injury in a hot and dry desert environment, it is impossible to realistically simulate the hot and dry desert environment and to effectively control the simulated parameters, such as temperature and humidity in the desert environment. This results in a slow production process, and consequently, the performance of the animal model does not closely resemble clinical standards. Therefore, we propose an experimental chamber to simulate rat injury in a hot and dry desert environment. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1

[0023] Reference Figures 1 to 4An experimental chamber for simulating damage to rats in a hot and dry desert environment includes a chamber body 1, with doors 2 hinged to both ends of the front side of the chamber body 1, and a controller 3 is installed on one of the doors 2.

[0024] The bottom inner wall of the cabin 1 is provided with a sand layer 4 to simulate a desert environment;

[0025] The cabin 1 is equipped with a humidification device, a dehumidification device, a heating device, and a temperature and humidity detection device;

[0026] Ultraviolet lamps 10 are evenly arranged on the top of the cabin 1. Ultraviolet radiation is simulated by irradiating the cabin with ultraviolet lamps 10.

[0027] The humidification device includes a water tank 5 with a water inlet on top for replenishing water. The water tank 5 is mounted on the cabin 1, and a water pump 6 is mounted on top of the cabin 1. The water pump 6 is electrically connected to the controller 3. The input end of the water pump 6 is connected to the water tank 5, and the output end of the water pump 6 passes through the cabin 1 and is connected to one end of a hose 7. The other end of the hose 7 is connected to a spray disc 8. The rear end of the spray disc 8 is connected to the output end of an electric guide rail 9, which is electrically connected to the controller 3. The electric guide rail 9 is horizontally mounted on the rear inner wall of the cabin 1. When the humidity is insufficient, the water pump 6 is turned on, and the water pump 6 delivers water from the water tank 5 to the spray disc 8 through the hose 7. At the same time, the electric guide rail 9 drives the spray disc 8 to move horizontally back and forth, thus evenly spraying water mist into the cabin 1 to increase humidity.

[0028] The dehumidification device includes a fixed cylinder 11, which is connected to the chamber 1. A dehumidifying fan 12 is installed inside the fixed cylinder 11 and is electrically connected to the controller 3. When the humidity is too high, the dehumidifying fan 12 can be turned on.

[0029] The heating device includes a support cylinder 14, which is connected to the cabin 1. An electric heating plate 15 and a blower 16 are installed inside the support cylinder 14. Both the electric heating plate 15 and the blower 16 are electrically connected to the controller 3. When the temperature is low, hot air can be delivered into the cabin 1 by the simultaneous operation of the electric heating plate 15 and the blower 16.

[0030] A filter screen 13 is provided on the left side of the fixed cylinder 11, and a filter screen 17 is provided on the right side of the support cylinder 14. Through the filter screen 13 and the filter screen 17, while ensuring that the chamber 1 is connected to the outside air, dust is prevented from entering the chamber 1, thus maintaining the cleanliness of the experiment inside the chamber 1.

[0031] The temperature and humidity detection device includes a mounting slot 18. Both ends of the top of the mounting slot 18 are higher than the middle position of the top of the mounting slot 18, allowing the gas delivered to the temperature and humidity sensor 21 to be discharged from the top. Mounting blocks connected to the top of the chamber 1 are provided at both ends of the top of the mounting slot 18. Partitions 19 are provided on both sides of the middle position of the top of the mounting slot 18, with the bottoms of both sets of partitions 19 higher than the inner wall of the bottom of the mounting slot 18. Air inlet slots 20 are provided on both sides of the mounting slot 18, opposite to the partitions 19. Exhaust fans 22, connected to the inner wall of the mounting slot 18, are provided on the side of the two sets of partitions 19 that are furthest apart. The height of the air inlet slots 20, exhaust fans 22, and the bottom of the partitions 19 gradually decreases. The top of the mounting slot 18 is open to exhaust gas. A temperature and humidity sensor 21 is installed inside the mounting slot 18 between two sets of partitions 19. Both the exhaust fan 22 and the temperature and humidity sensor 21 are electrically connected to the controller 3. When the exhaust fan 22 is working, the air in the chamber 1 enters through the air inlet slot 20, and after turning through the space between the partition 19 and the bottom inner wall of the mounting slot 18, it is transmitted to the middle position inside the mounting slot 18, which can quickly transmit the air to the temperature and humidity sensor 21 to detect the temperature and humidity in the chamber 1 in real time. The high-speed air is transmitted to the temperature and humidity sensor 21 after turning, which can avoid the temperature and humidity sensor 21 being damaged by long-term direct impact of high-speed air.

[0032] Example 2

[0033] Reference Figures 1 to 2A horizontal bar 23 runs through the top of the chamber 1. Both ends of the horizontal bar 23 are equipped with racks 24, allowing the horizontal bar 23 to move. Both racks 24 move laterally accordingly. Gears 25 are meshed at the bottom of both racks 24. Mounting shafts are located on the top of both sides of the chamber 1, with the gears 25 respectively mounted on them. Striking rods 26 are mounted on both mounting shafts, corresponding to filter screen 13 and filter screen 17 respectively. When the racks 24 swing back and forth via the mounting shafts, they strike filter screens 13 and 17, knocking off the dust adhering to them, ensuring the efficiency of the chamber 1 in regulating temperature and humidity. The top of the right rack 24 is hinged to one end of a movable rod 27, and the other end of the movable rod 27 is hinged to the top of a turntable 28. The turntable 28 is mounted on a fixed shaft, which is rotatably connected to the chamber via bearings. At the top of body 1, a driven bevel gear 29 is sleeved on a fixed shaft. A driving bevel gear 30 is meshed on the driven bevel gear 29. The driving bevel gear 30 is sleeved on a connecting shaft 31, which is connected to the output shaft of the water pump 6. A support bearing 32 is provided on body 1 and is rotatably connected to the connecting shaft 31 to improve the stability of the connecting shaft 31 during rotation. When the water pump 6 periodically humidifies the interior of body 1, the water pump 6 can drive the connecting shaft 31 to rotate, causing the driving bevel gear 30 to drive the driven bevel gear 29 to rotate, which in turn causes the turntable 28 to rotate. This causes the movable rod 27 to drive the right rack rod 24 to move back and forth laterally, which in turn drives the gear 25 to rotate back and forth, thereby causing the striking rod 26 to swing back and forth. Thus, when the water pump 6 periodically humidifies the interior of body 1, it can simultaneously remove dust from filter screen 13 and filter screen 17, ensuring the efficiency of body 1 in regulating temperature and humidity.

[0034] The rest of the structure is the same as in Example 1.

[0035] Usage: A desert environment is simulated using sand layer 4, and ultraviolet radiation is simulated by ultraviolet lamp 10. The exhaust fan 22 draws air from the cabin 1 through the air intake slot 20, then passes through the space between the partition 19 and the bottom inner wall of the mounting slot 18 before being transported to the center of the mounting slot 18. This allows for rapid transmission to the temperature and humidity sensor 21, enabling real-time monitoring of the temperature and humidity within the cabin 1. The high-speed air transmission to the temperature and humidity sensor 21 avoids long-term direct impact from high-speed air, preventing damage. When humidity is insufficient, the water pump 6 is activated, pumping water from the water tank 5. Water is delivered to the spray disc 8 through the hose 7, and the spray disc 8 is driven to move back and forth laterally by the electric guide rail 9, so that the water mist can be evenly sprayed into the chamber 1 to increase the humidity. When the humidity is too high, the dehumidifier 12 can be turned on. When the temperature is low, the electric heating plate 15 and the blower 16 work together to send hot air into the chamber 1. When the temperature and humidity sensor 21 detects that the temperature inside the chamber 1 is 40-42℃ and the humidity is about 10%, no further adjustment is needed. This allows the experimental chamber to simulate the dry and hot desert environment, effectively control the simulated parameters, improve production efficiency, and make the animal model produced meet clinical standards.
