Description

Technical Field

[0001] The invention belongs to the field of underwater animal experiments, and in particular relates to a life support system for underwater animal experiments. Background Art

[0002] In underwater animal experiments using Bama pigs as experimental subjects, we need to provide the experimental animals with a system that supports their normal survival underwater, and we also need to protect the brains and internal organs of the experimental animals separately. However, the existing experimental equipment lacks such a system. Because Bama pigs are short, small, short, and round, with a docile temperament, and the weight of adults is comparable to that of humans, and the alpha rhythm of the Bama pig's brain and the inherent frequency of its internal organs are the same as those of humans, we chose Bama pigs as experimental subjects in underwater animal experiments. However, Bama pigs are timid and easily frightened, and they tend to defecate after being frightened. In order to ensure the smooth progress of the experiment, it is also necessary to avoid the adverse effects of Bama pig excrement on related underwater experimental equipment.

[0037] 2. The present application uses the design of driving the front side cover and the rear side cover to rotate through the opening and closing module, and combined with the design of the first elastic airbag, the second elastic airbag and the third elastic airbag, it is possible to easily load the Bama pig.

[0038] 3.

At the same time, it can also adapt to the large and soft ears of Bama pigs, so that the earplug body can better block the ear canal of Bama pigs, avoiding the Bama pigs from being frightened by the sounds in the ocean, thereby solving the problem of Bama pigs struggling due to being frightened by the sounds and affecting the smooth progress of the experiment.

[0042] 7. The present application avoids scaring the Bama pigs by the light in the ocean through the design of the eye mask body and the arc-shaped member.

[0043] 8. This application ensures the normal survival of Bama pigs in the ocean during the experiment through the design of the mask component and the ventilation component, ensuring the normal progress of the experiment. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0060] See also Figures 1 to 7The present invention provides a life support system for underwater animal experiments, comprising: a diving module 14, a cover module 11, a breathing module 15, a restraining module 16, and an opening and closing module 13. A diving chamber 141 is provided inside the diving module 14, and the cover module 11, the breathing module 15, and the restraining module 16 are all installed in the diving chamber 141. Various electrical components and hydraulic components are also placed in the diving chamber 141. When conducting an experiment, the experimental vessel drops the diving module 14 into the experimental sea area, and then the experimental vessel evacuates to a safe area, and then transmits a vibration signal to the experimental sea area where the diving module 14 is dropped.

[0061] The cover module 11 includes a brain cover component 111, an internal organ cover component 112, a buttocks cover component 113, a front cover 114, a rear cover 115, a bottom cover 118, a first partition plate 116 and a second partition plate 117. The brain cover component 111, the internal organ cover component 112, the buttocks cover component 113, the front cover 114, the rear cover 115, the bottom cover 118, the first partition plate 116 and the second partition plate 117 are all provided with an interlayer, which can block the propagation of sound waves, thereby avoiding the damage of the vibration signal to the Bama pig in the cover module 11. The interlayer can be filled with carbon dioxide or set to a vacuum;

[0062] The front cover 114, the brain cover component 111, the viscera cover component 112, the buttocks cover component 113 and the rear cover 115 are sequentially connected from front to back and enclosed with the bottom cover 118 to form a closed protection room. The first partition plate 116 is installed at the connection between the brain cover component 111 and the viscera cover component 112, and the second partition plate 117 is installed at the connection between the viscera cover component 112 and the buttocks cover component 113. The protection room is partitioned from front to back into three closed spaces by the first partition plate 116 and the second partition plate 117. The three closed spaces protect the brain, viscera and buttocks of the Bama pig respectively.

[0063] The opening and closing module 13 drives the brain cover component 111, the internal organs cover component 112 and the buttocks cover component 113 to open and close respectively;

[0064] A first elastic airbag 1161 is installed in the middle of the first partition plate 116, and a first opening and closing hole 1162 is opened in the first elastic airbag 1161; a second elastic airbag 1171 is installed in the middle of the second partition plate 117, and a second opening and closing hole 1172 is opened in the second elastic airbag 1171. When the Bama pig is loaded, the Bama pig passes through the first opening and closing hole 1162 and the second opening and closing hole 1172. The first elastic airbag 1161 and the second elastic airbag 1171 are filled with carbon dioxide gas, which has a stronger absorption effect on sound waves than nitrogen and oxygen.

[0065] The first elastic airbag 1161 is embedded in the first partition plate 116. When the Bama pig passes through the first opening and closing hole 1162, the inner circle of the first opening and closing hole 1162 on the first elastic airbag 1161 fits into the neck of the Bama pig.

[0066] The second elastic airbag 1171 is embedded in the second partition plate 117. When the Bama pig passes through the second opening and closing hole 1172, the inner circle of the second opening and closing hole 1172 on the second elastic airbag 1171 fits into contact with the pig's body slightly forward of the base of its hind legs.

[0067] When it is necessary to detect damage to the brain of the Bama pig caused by the emitted vibration signal of a certain frequency, the brain cover component 111 is driven to open, and the viscera cover component 112 and the buttocks cover component 113 are kept closed;

[0068] When it is necessary to detect damage to the internal organs caused by a vibration signal of a certain frequency, the internal organ cover component 112 is driven to open, and the brain cover component 111 is kept closed;

[0069] Similarly, the device can also detect the damage to a Bama pig when its brain and internal organs are protected, but its buttocks and limbs are exposed and it is attacked by a vibration signal; or when its brain, internal organs and buttocks are all protected, but only its limbs are exposed and it is attacked by a vibration signal.

[0070] The restraining module 16 includes a restraining component 161 and a feces collecting component 162. The restraining component 161 can effectively limit the range of movement of the Bama pig during the underwater experiment. The feces collecting component 162 includes a first diaper 1621, a first conduit 1622 and a feces collecting box 1623. The Bama pig is installed inside the cover module 11. The first diaper 1621 is worn on the buttocks of the Bama pig and can effectively absorb the excrement of the Bama pig. The feces collecting box 1623 is set outside the cover module 11. The first conduit 1 622 passes through the cover module 11 and connects the first diaper pants 1621 and the feces collection box 1623. The first conduit 1622 guides the excrement in the first diaper pants 1621 into the feces collection box 1623. The feces collection box 1623 is sealed to prevent the excrement from leaking out. The present application ultimately avoids the problem of Bama pig excrement having an adverse effect on underwater experimental equipment during underwater animal experiments through the design of the first diaper pants 1621, the first conduit 1622 and the feces collection box 1623.

[0071] For this example, please refer to Figures 2 to 5 The brain cover component 111 includes a left brain cover 1111 and a right brain cover 1112. The bottom of the left brain cover 1111 is rotatably connected to the left side of the bottom cover 118, and the bottom of the right brain cover 1112 is rotatably connected to the right side of the bottom cover 118. The front end of the left brain cover 1111 and the front end of the right brain cover 1112 are both in contact with the front cover 114, and the rear end of the left brain cover 1111 and the rear end of the right brain cover 1112 are both in contact with the front end of the visceral cover component 112.

[0072] The opening and closing module 13 drives the left brain cover 1111 and the right brain cover 1112 to rotate respectively. When the left brain cover 1111 rotates clockwise to the limit and the right brain cover 1112 rotates counterclockwise to the limit, the front cover 114, the left brain cover 1111, the right brain cover 1112, the first partition plate 116 and the bottom cover 118 form an enclosed space to protect the brain. Here is a specific structural form of the brain cover component 111 and the way in which the opening and closing module 13 drives it to open and close. Other ways in the present technical field can also be used to achieve the opening and closing of the brain cover component 111.

[0073] For this example, please refer to Figures 2 to 5The visceral cover component 112 includes a left visceral cover 1121 and a right visceral cover 1122. The bottom of the left visceral cover 1121 is rotatably connected to the left side of the bottom cover 118, and the bottom of the right visceral cover 1122 is rotatably connected to the right side of the bottom cover 118. The front end of the left visceral cover 1121 is in contact with the rear end of the left brain cover 1111, and the front end of the right visceral cover 1122 is in contact with the rear end of the right brain cover 1112. The rear ends of the left visceral cover 1121 and the rear ends of the right visceral cover 1122 are both in contact with the front end of the buttocks cover component 113.

[0074] The opening and closing module 13 drives the left visceral cover 1121 and the right visceral cover 1122 to rotate respectively. When the left visceral cover 1121 rotates clockwise to the limit and the right visceral cover 1122 rotates counterclockwise to the limit, the first partition plate 116, the left visceral cover 1121, the right visceral cover 1122, the second partition plate 117 and the bottom cover 118 form an enclosed space to protect the internal organs. Here is a specific structural form of the visceral cover component 112 and the way in which the opening and closing module 13 drives it to open and close. Other methods in the present technical field can also be used to realize the opening and closing of the visceral cover component 112.

[0075] For this example, please refer to Figures 2 to 5 The hip cover component 113 includes a left hip cover 1131 and a right hip cover 1132. The bottom of the left hip cover 1131 is rotatably connected to the left side of the bottom cover 118, and the bottom of the right hip cover 1132 is rotatably connected to the right side of the bottom cover 118. The front end of the left hip cover 1131 is fitted with the rear end of the left visceral cover 1121, and the front end of the right hip cover 1132 is fitted with the rear end of the right visceral cover 1122. The rear ends of the left hip cover 1131 and the rear ends of the right hip cover 1132 are both fitted with the rear side cover 115.

[0076] The opening and closing module 13 drives the left hip cover 1131 and the right hip cover 1132 to rotate respectively. When the left hip cover 1131 rotates clockwise to the limit and the right hip cover 1132 rotates counterclockwise to the limit, the second partition plate 117, the left hip cover 1131, the right hip cover 1132, the rear cover 115 and the bottom cover 118 form an enclosed space to protect the buttocks. Here is a specific structural form of the hip cover component 113 and the way in which the opening and closing module 13 drives it to open and close. Other ways in the present technical field can also be used to realize the opening and closing of the hip cover component 113.
