Description

Technical Field

[0001] This invention relates to the field of underwater diving breathing and life support technology, and in particular to a system and method for monitoring underwater breathing and life support in beagles. Background Technology

[0002] Diving medicine, also known as underwater medicine, is a discipline that studies and addresses various medical issues arising during diving operations. This includes research on the physiological responses and pathological changes of organisms working in underwater and high-pressure environments, the prevention and treatment of diving-related diseases, and the hygienic requirements and medical support measures for diving operations. Research in diving medicine typically begins with animal experiments before progressing to human trials.

[0003] Beagles are a common laboratory animal with many natural advantages. However, as terrestrial mammals, beagles cannot survive underwater for long periods, similar to humans. Underwater experiments can also lead to decompression sickness or decompression sickness in laboratory animals. In order to operate normally underwater, specialized underwater breathing and life support systems must be used as auxiliary equipment. At present, there are no research results on corresponding equipment and systems specifically for beagles.

[0004] In experiments related to diving medicine, it is essential to keep experimental animals in an underwater environment for extended periods. While some advanced diving equipment exists, it is designed for humans, making it unsuitable for animals like beagles. Therefore, ensuring that beagles maintain normal vital signs underwater for a sustained period is crucial. A review of previous literature revealed some research on the underwater respiratory systems of animals.

[0005] CN115517178A discloses a saturation diving animal experimental system;

[0006] CN109835448A discloses a positive pressure breathing device for a diving experiment of Bama miniature pigs; these technologies are not applicable to beagle dogs and cannot flexibly adjust the angle in the water.

[0007] However, the following problems exist:

[0008] ① There is no matching system or equipment specifically designed for experimental animals like beagles; ② Some underwater breathing systems only maintain underwater breathing function and cannot simultaneously conduct multimodal observation and monitoring of the basic physiological indicators and emotional behavior of the experimental subjects; ③ Due to problems with equipment materials and design, experimental animals may experience maladaptation, discomfort, or even stress responses, thus affecting the objectivity of experimental results; ④ During the maintenance of respiratory function, the lack of real-time monitoring of physiological indicators makes it impossible to properly maintain the respiratory function of experimental animals, which may lead to problems such as hypoxia or even oxygen poisoning. Summary of the Invention

[0009] Purpose of the invention: To provide a more effective system and method for monitoring underwater breathing and life support in beagles, the specific purpose of which is described in the detailed implementation section for several substantial technical effects.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A beagle underwater breathing and life support system, characterized in that,

[0012] The maintenance system includes a base plate 19, on which a bottom fixing structure (17) and a fixing structure 5 are arranged; an animal carrying part 18 is arranged between the bottom fixing structure (17) and the fixing structure 5, and an animal can be tied in the animal carrying part 18.

[0013] An inverted conical fixed glass cover base 6 is connected to the base plate 19 via a connecting plate 2;

[0014] The head of an animal can pass through the head passage hole 1 below the fixed glass cover base 6;

[0015] The fixed glass cover base 6 can be fixed to the glass cover 10 through the fixed glass cover base 6;

[0016] The glass cover 10 and the fixed glass cover base 6 together comprise one or more openings 9;

[0017] A camera mounting plate 14 is arranged on the fixed glass cover base 6, and a camera 13 is arranged on the camera mounting plate 14.

[0018] A further technical solution of the present invention is that the bottom fixing structure (17) and the fixing structure (5) can move up and down along the base plate 19 and can each be pressed onto the base plate 19 by fixing bolts 15.

[0019] A further technical solution of the present invention is that the rubber band selected as the fixing material has a certain degree of water resistance. The rubber band can bind the animal, and the thickened rubber pad at the part in contact with the limb prevents additional damage to the experimental animal caused by the fixing.

[0020] A further technical solution of the present invention is that the fixed glass cover base 6 is connected to the torso fixing bracket, i.e., the fixed glass cover base 6. The fixed glass cover base 6 has a gas inlet and three sensor inlets. The gas inlet is used for gas exchange, and the three sensor inlets are used for physiological index detection. The glass cover is a spherical organic glass cover with good pressure resistance and light transmittance. It can observe the physiological and behavioral conditions of experimental animals underwater in real time.

[0021] A further technical solution of the present invention is that the gas outlet is located above the glass cover 10, which facilitates the exhalation of gas and avoids the retention of carbon dioxide; the oxygen can be supplied under positive pressure to better ensure the oxygen supply for experimental animals; both the gas inlet and the gas outlet are connected to pressure-resistant hoses to facilitate the entry and exit of gas.

[0022] A further technical solution of the present invention is that the fixed glass cover base 6 can be sealed to the glass cover 10 through the fixed glass cover base 6. The connection part between the fixed glass cover base 6 and the neck of the beagle, namely the head through hole 1, is filled with silicone and rubber. After filling, only the neck through hole in the middle is retained. The silicone and rubber filling provides both waterproof sealing and comfort.

[0023] A further technical solution of the present invention is that the camera 13 is a waterproof camera; it also includes an animal monitor, which can detect the physiological characteristics of the experimental animal in real time.

[0024] A further technical solution of the present invention is that the fixed glass cover base 6 is connected to the upper fixed plate 11 through the upper fixed plate support structure 12; a columnar object is arranged on the upper fixed plate 11 for wiring.

[0025] A further technical solution of the present invention is that it also includes an animal angle adjustment structure in water. The structure of the animal angle adjustment structure in water is as follows: the back of the base plate 19 includes a base hinge portion 20 as a hinge seat. Each of the two base hinge portions 20 is hinged to a hinge plate. The two hinge plates are hinge plate one (21) and hinge plate two (22). Each of hinge plate one (21) and hinge plate two (22) includes multiple adjustment holes 23. By adjusting the overlap of the adjustment holes 23 on different hinge plates one (21) and hinge plate two (22), the tilt angle of the base plate 19 after entering the water can be adjusted. It also includes one or more ropes tied in the adjustment holes 23 to suspend the entire device. Adjusting the tilt angle of the base plate 19 after entering the water can adjust the tilt angle of the animal in the water.

[0026] A method for monitoring underwater breathing and life support in a beagle, characterized by utilizing the breathing and life support system described in any one of the above claims, comprising the following steps.

[0027] Limb and trunk fixation: This fixation frame can be finely adjusted according to the size of the experimental dog to ensure good fixation and comfort. The fixation material is rubber bands, which have a certain degree of water resistance. Thick rubber pads are added to the parts that come into contact with the limbs to prevent additional damage to the experimental animal caused by fixation.

[0028] Head fixation: The head is inserted into the fixed glass cover base 6, and the gas supply system and dose adjustment are completed by the ventilator;

[0029] Weight adjustment of the fixation frame: The combined weight of the fixation frame and the experimental animal will be slightly greater than the buoyancy of the animal after it enters the water, so as to achieve a balance and better simulate the diving or underwater experimental environment.

[0030] After fixation, the life support system of the beagle is tested: This system is mainly completed by an animal monitor, which can detect the physiological characteristics of the experimental animal in real time. The skin at the electrode placement site needs to be shaved, cleaned and dried to ensure that the electrodes are firmly attached to the skin. Then the electrodes, wires and recorder are fixed. The basic physiological indicators such as blood pressure, blood oxygen, pulse, body temperature and electrocardiogram of the experimental animal can be detected in a non-invasive way. The physiological indicators such as blood oxygen can guide the adjustment and operation of the ventilation system.

[0031] After connecting to the system, observe whether the basic physiological characteristics of the experimental animals are normal. If they are normal, proceed to the next step of the experiment.

[0032] After rechecking the sealing of the breathing support device and the operation of the entire device, and confirming that everything was normal, the underwater environment experiment on the experimental animals was started according to the experimental requirements.

[0033] The present invention, employing the above technical solution, has the following beneficial effects compared to the prior art: ① It enables long-term underwater breathing and life support for beagles; ② It allows for the selection of gases with different compositions for different diving durations and depths, better preventing decompression sickness or oxygen poisoning; ③ It allows for real-time monitoring of beagles' emotional and behavioral changes and vital signs in the underwater environment; ④ It effectively reduces the stress response of experimental animals caused by the fixation frame.

[0046] The maintenance system includes a base plate 19, on which a bottom fixing structure (17) and a fixing structure 5 are arranged; an animal carrying part 18 is arranged between the bottom fixing structure (17) and the fixing structure 5, and an animal can be tied in the animal carrying part 18.

[0052] The substantive technical effects and implementation process of the technical solution presented herein, i.e., its basic functions, are as follows:

[0053] A method for monitoring underwater breathing and life support in a beagle, characterized by utilizing the breathing and life support system described in any one of the above claims, comprising the following steps.

[0054] Limb and trunk fixation: This fixation frame can be finely adjusted according to the size of the experimental dog to ensure good fixation and comfort. The fixation material is rubber bands, which have a certain degree of water resistance. Thick rubber pads are added to the parts that come into contact with the limbs to prevent additional damage to the experimental animal caused by fixation.

[0055] Head fixation: The head is inserted into the fixed glass cover base 6, and the gas supply system and dose adjustment are completed by the ventilator;

[0056] Weight adjustment of the fixation frame: The combined weight of the fixation frame and the experimental animal will be slightly greater than the buoyancy of the animal after it enters the water, so as to achieve a balance and better simulate the diving or underwater experimental environment.

[0057] After fixation, the life support system of the beagle is tested: This system is mainly completed by an animal monitor, which can detect the physiological characteristics of the experimental animal in real time. The skin at the electrode placement site needs to be shaved, cleaned and dried to ensure that the electrodes are firmly attached to the skin. Then the electrodes, wires and recorder are fixed. The basic physiological indicators such as blood pressure, blood oxygen, pulse, body temperature and electrocardiogram of the experimental animal can be detected in a non-invasive way. The physiological indicators such as blood oxygen can guide the adjustment and operation of the ventilation system.

[0058] After connecting to the system, observe whether the basic physiological characteristics of the experimental animals are normal. If they are normal, proceed to the next step of the experiment.

[0059] After rechecking the sealing of the breathing support device and the operation of the entire device, and confirming that everything was normal, the underwater environment experiment on the experimental animals was started according to the experimental requirements.

[0060] In the more specific implementation process, the selection of materials is crucial in the design of this system. The helmet material suitable for beagles must first be waterproof and airtight, so we chose plexiglass. At the same time, special treatment was also carried out at the joints between different materials. In addition, the filling material at the joint between the helmet and the experimental animal is another key point. This part must be both waterproof and airtight, and also have a certain degree of comfort. Otherwise, it will directly affect the experimental animal's mood and behavior underwater, leading to the experimental animal's non-cooperation and the failure of the experiment.

[0061] The system consists of five parts: a helmet for laboratory animal respiratory and life support, a physiological indicator detection system, an air supply system, a behavior observation and monitoring system, and a system fixation bracket.

[0062] ① Helmet for experimental animal respiratory and life support system: Used to fix the head of experimental animals. The helmet includes a window for observing animal behavior and physiological indicators, which is made of a spherical plexiglass cover. The glass cover is pressure-resistant and transparent, allowing real-time observation of the physiological and behavioral conditions of experimental animals underwater. The second part of the helmet consists of a base for fixing the glass cover, which is connected to the plexiglass head cover with a sealing gasket to prevent water and air leakage. The system includes: ① A fixed glass dome base with three sensor ports for gas exchange and physiological indicator detection. It also features an underwater camera monitoring bracket to hold the underwater camera, allowing real-time observation of the animals' emotions and behaviors during the experiment; ② An animal respiratory and life-sustaining physiological indicator monitoring system: During the experiment, an animal electrocardiogram monitor is used to monitor the animals' respiration, heart rate, blood pressure, and other basic vital signs in real time, facilitating observation of the animals' vital signs; ③ An animal respiratory and life-sustaining system supply system: This system provides pure oxygen to the hood in real time during the experiment and removes exhaled CO2, monitoring the oxygen content within the hood; ④ An animal respiratory and life-sustaining system behavior observation and monitoring system: Utilizing an underwater camera system, real-time observation and video recording of the animals' emotional and behavioral changes underwater during the experiment; ⑤ An animal respiratory and life-sustaining system fixation bracket: Used to fix the animal's respiratory and life-sustaining system underwater.

[0063] Effects: ① Enabled long-term underwater breathing and life support for beagles; ② Allowed the selection of gases with different compositions for different diving durations and depths, better preventing decompression sickness or oxygen poisoning; ③ Allowed real-time monitoring of beagles' emotional and behavioral changes and vital signs in the underwater environment; ④ Effectively reduced the stress response of experimental animals caused by the fixation frame.

[0064] Example 2: As a further improvement, parallel, or optional independent solution, the bottom fixing structure (17) and fixing structure 5 can move up and down along the base plate 19 and are each pressed against the base plate 19 by fixing bolts 15. The substantive technical effect and implementation process of this technical solution, i.e., its basic function, are as follows: the vertical movement of the bottom fixing structure (17) and fixing structure 5 can adjust the spacing to appropriately adapt to the animal's body shape.

[0065] Example 3: As a further improvement, parallel, or optional independent solution, the rubber band chosen as the fixing material has a certain degree of water resistance. The rubber band can bind the animal, and the thickened rubber pad at the contact point with the limbs prevents additional damage to the experimental animal caused by the fixing. The substantial technical effect and implementation process of the technical solution here, i.e., its basic function, are as follows: This embodiment provides a specific fixing structure, and similar implementation structures are all within the protection scope of this patent.

[0066] Example 4: As a further possible improvement, parallel solution, or optional independent solution, the fixed glass cover base 6 is connected to the torso fixing bracket, i.e., the fixed glass cover base 6. The fixed glass cover base 6 has a gas inlet and three sensor inlets. The gas inlet is used for gas exchange, and the three sensor inlets are for physiological index detection. The glass cover is a spherical organic glass cover with good pressure resistance and light transmittance. It can observe the physiological and behavioral status of experimental animals underwater in real time. The substantial technical effect and implementation process of the technical solution described herein, i.e., its basic function, are as follows: This patent can judge the animal's status in real time, innovatively starting from the animal's behavior, to assist in the experimental situation of the animal.

[0067] Example 5: As a further improvement, parallel, or optional independent solution, the gas outlet is located above the glass cover 10, facilitating the exhalation of gas and preventing carbon dioxide retention; positive pressure oxygen supply better ensures the oxygen supply to the experimental animals; both the gas inlet and outlet are connected with pressure-resistant hoses for convenient gas entry and exit. The substantive technical effects and implementation process of this technical solution, i.e., its basic functions, are as follows: Because different gases may be required, this embodiment is only one specific gas connection method; similar implementation methods are all within the protection scope of this patent.

[0068] Example 6: As a further improvement, parallel, or optional independent solution, the fixed glass cover base 6 can be sealed to the glass cover 10 through the fixed glass cover base 6. The connection between the fixed glass cover base 6 and the beagle's neck, i.e., the head through hole 1, is filled with silicone and rubber. After filling, only the neck through hole in the middle is left open. The silicone and rubber filling provides both waterproof sealing and comfort.

[0069] Example 7: As a further improvement, parallel, or optional independent solution, the camera 13 is a waterproof camera; it also includes an animal monitor that can detect the physiological characteristics of the experimental animal in real time.

[0070] Example 8: As a further improvement, parallel, or optional independent solution, the fixed glass cover base 6 is connected to the upper fixed plate 11 via the upper fixed plate support structure 12; a columnar object is arranged on the upper fixed plate 11 for wiring.

[0071] Example 9: As a further improvement, parallel, or optional independent solution, it also includes an animal water angle adjustment structure. The structure of the animal water angle adjustment structure is as follows: the back of the base plate 19 includes a base hinge portion 20 as a hinge seat. Each of the two base hinge portions 20 is hinged to a hinge plate. The two hinge plates are hinge plate one (21) and hinge plate two (22). Each of hinge plate one (21) and hinge plate two (22) includes multiple adjustment holes 23. By adjusting the overlap of the adjustment holes 23 on different hinge plates one (21) and hinge plate two (22), the tilt angle of the base plate 19 after entering the water can be adjusted. It also includes one or more ropes tied in the adjustment holes 23 to suspend the entire device. Adjusting the tilt angle of the base plate 19 after entering the water can adjust the tilt angle of the animal in the water. The substantive technical effects and implementation process of the technical solution provided herein, i.e., its basic functions, are as follows: The solution provided in this embodiment is that it can flexibly adjust whether the animal is tilted or horizontal underwater, because different positions may result in different diving characteristics of the animal. This embodiment fills a gap in the industry.

[0072] Innovatively, each of the above effects exists independently, yet a single structure can be used to combine the results.

[0073] It should be noted that the multiple solutions provided in this patent include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other without conflict to achieve multiple effects.

[0074] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
