Description

Technical Field

[0001] The invention relates to the field of animal transport equipment, and more specifically to a portable scientific research animal air transport life support and biomedical culture experimental device. Background Art

[0002] With the rapid development of life science and pharmaceutical industries, the demand for experimental animals is increasing. Providing standardized experimental animals and high-level animal experimental conditions and instruments is an important condition for ensuring accurate scientific research and drug experimental results. Scientific research has higher and higher requirements for the quality of experimental animals, which refers to experimental animals that do not carry major potential infections or conditional pathogens and pathogens that interfere with scientific experiments, except for pathogens that should be excluded by clean animals. In the process of conducting pharmacological animal experiments, there is an actual need to transport experimental animals. In principle, pathogens are not allowed to exist in the equipment or space used for transportation, and the corresponding cleanliness requirements need to be guaranteed to avoid many non-pathogenic microorganisms gradually entering the body of animals that do not have specific pathogens, causing certain pathogens to have greater variability and bring about the possibility of causing disease, so that latently infected animals gradually become factors that interfere with experimental results.

[0003] At present, the conventional transportation methods for ordinary small animals are freight methods such as railways and trucks. The transportation time is long, and its harsh transportation environment makes it difficult to ensure the life safety of laboratory research animals. Secondly, there are few systematic studies on intelligent, practical and reliable animal biomedical culture experimental devices in the prior art, and the research cost is high and the economic benefits are poor. For small scientific research animals with important research value, it is often necessary to use efficient and comfortable air transportation methods to transfer from a laboratory in one place to a laboratory in another area. Due to its important scientific research value, it requires staff to escort it throughout the journey, so it needs to be transported by passenger plane. During the transportation process, these animals will produce excrement and foul-smelling gases, which can easily cause suffocation of the transported animals and affect the flight experience of other passengers on the plane. Therefore, it is necessary to collect and process the animal's excrement automatically and in a timely manner, and design a closed device to prevent odor leakage.

[0004] During the transportation and biomedical culture experiments, these scientific research animals need to be provided with life support. Therefore, in a closed environment, it is necessary to provide automatic watering devices, feeding devices, waste collection devices, camera real-time monitoring systems, lighting devices, oxygen replacement and ammonia treatment devices to ensure their health and safety during air transportation. The existing animal culture experimental devices are bulky and inconvenient to carry during transportation.

The gas enters from the air inlet 2-2 of the oxygen replacement module, passes through the four grids of the mesh air purification box 2-4 from left to right, and flows out from the air outlet 2-3 of the oxygen replacement module. The desiccant is used to adsorb water vapor discharged from the animal culture module; the high molecular activated carbon and molecular sieve ammonia adsorbent are used to adsorb harmful gases such as ammonia discharged from the animal culture module; the potassium superoxide oxygen generator reacts with the carbon dioxide discharged by the animals in the animal culture module to produce oxygen.

[0064] For further information, see Figure 2 and Figure 3 The rechargeable battery pack module 3 is fixed to the upper left of the suitcase body 1 and is mainly used to power the life support device.

The rechargeable battery pack module 3 is electrically connected to the oxygen replacement and ammonia treatment module 2, the animal culture module 4, the camera monitoring and visualization information processing module 5 and the lighting component 6 respectively to realize internal power supply. The rechargeable battery pack module 3 has the functions of charging and storing electricity, and can also power the life support device in the absence of a power supply interface.

[0065] For further information, see Figure 5 and Figure 6 The animal culture module 4 is a sealed animal culture module box 4-1, and a fan 4-2, a drawer-type feeding cage component 4-3, a waste collection device 4-4, a sensor and a temperature control component 4-5, a control panel 4-6 and an air duct 4-7 are arranged inside the animal culture module box 4-1. The animal culture module 4 is fixed in the middle position of the suitcase 1 by four mounting feet.

[0066] The material of the animal culture module box 4-1 should be transparent acrylic, and can be processed by CNC or injection molding according to the transparency requirements. The outer wall of the animal culture module box 4-1 is provided with an electrical connector 4-1-1, a culture module air inlet 4-1-2 and a culture module air outlet 4-1-3 connected to the air duct 4-7, and the control panel 4-6 is electrically connected to the electrical connector 4-1-1, the fan 4-2, the drawer-type cage assembly 4-3, the waste collection device 4-4, the sensor and the temperature control assembly 4-5. The control panel 4-6 is electrically connected to the touch control display screen 1-6, and various devices in the animal culture module 4 can be controlled by the touch control display screen 1-6.

[0067] The air duct 4-7 of the animal culture module 4 is made of aluminum alloy. Two fans 4-2 are fixedly installed on the threaded holes reserved in the air duct 4-7 and are located directly above the drawer-type breeding cage assembly 4-3. The waste collection device 4-4 is located directly below the drawer-type breeding cage assembly 4-3. The two fans 4-2 are staggered to avoid gas turbulence. The culture module air inlet 4-1-2 and the culture module air outlet 4-1-3 are respectively installed on the upper left and lower left sides of the animal culture module box 4-1. For specific air ducts and gas circuits, see Figure 5 .

[0068] For further information, see Figure 7The drawer-type feeding cage assembly 4-3 includes a feeding outer frame 4-3-1, a drawer flange and a handle 4-3-2 fixed on the outside of the feeding outer frame 4-3-1, and a feeding assembly 4-3-3 and a water feeding assembly 4-3-4 fixed on the inside of the feeding outer frame 4-3-1; the feeding outer frame 4-3-1 is also provided with a matching feeding inner frame 4-3-5, the feeding outer frame 4-3-1 is fixed with a gear 4-3-6, and the outer side of the feeding inner frame 4-3-5 is matched with a rack 4-3-7, and the two cooperate with each other to achieve a telescopic effect. The entire feeding cage is fixed on the side wall of the culture module. The feeding cage can be quickly taken out or placed by pulling out the handle.

[0069] For further information, see Figure 8 and Fig. 9 The water feeding assembly 4-3-4 includes a water feeding device box 4-3-4-1, a spring extrusion plate 4-3-4-2 and a water bag 4-3-4-3 are arranged inside the water feeding device box 4-3-4-1, and a spring water nozzle assembly 4-3-4-4 connected to the water bag 4-3-4-3 is fixed on the outside of the water feeding device box 4-3-4-1. The water feeding assembly 4-3-4 adopts the principle of spring extrusion to realize its automatic water feeding function. When the water bag is injected with pure water through the water filling port, the water outlet of the water bag is connected to the rear ends of the two water nozzles through a three-way hose connector and a hose, and the joint position can be reinforced by a clamp. The water bag is placed between the spring extrusion plate 4-3-4-2 and the inner wall of the water feeding device box 4-3-4-1, and the spring water nozzle assembly 4-3-4-4 is tightened on the threaded holes on the water tank. The water in the water bag can automatically flow to the spring drinking head after being squeezed by the spring. The front end of the spring water spout assembly 4-3-4-4 is composed of a spring ball and an ejector pin. The animals in the cage can drink water by licking the ejector pin of the spring drinking head. When the animal does not drink water, the spring pushes the steel ball against the drinking port due to its physical properties, and the water will not flow out. The spring squeezing device is welded in the groove of the two metal plates through the spring. The groove plays a limiting role. The spring squeezing device is fixed to the left inner wall of the water tank. In this implementation example, the water bag can be injected with either pure water or nutrient solution according to actual needs.

[0070] For further information, see Fig.10 and Fig.11 The waste collection device 4-4 includes a bottom plate bracket 4-4-1, and a motor 4-4-2, a transmission shaft 4-4-3, a first driven shaft 4-4-4, a second driven shaft 4-4-5 and a drying box 4-4-6 fixed on the bottom plate bracket 4-4-1. The output shaft of the motor 4-4-2 is fixedly connected to the transmission shaft 4-4-3. The first driven shaft 4-4-4 is provided with a water-absorbing filter cloth 4-4-7, and the second driven shaft 4-4-5 is provided with a wrapped sealing film 4-4-8.

[0071] The first driven shaft 4-4-4 and the second driven shaft 4-4-5 are fixed on both sides of the transmission shaft 4-4-3, respectively. The water-absorbing filter cloth 4-4-7 is wound from the bottom of the transmission shaft 4-4-3, and the wrapping sealing film 4-4-8 is wound from the top of the transmission shaft 4-4-3. An obtuse angle is formed between the water-absorbing filter cloth 4-4-7 and the wrapping sealing film 4-4-8. As the transmission shaft rotates, the water-absorbing filter cloth 4-4-7 carries animal excrement and transports it to the wrapping sealing film 4-4-8. After the animal excrement is sucked of excess water by the water-absorbing filter cloth 4-4-7, it is squeezed by the wrapping sealing film 4-4-8 and sealed in the sealing film. The running state of the motor 4-4-2 is controlled by sending instructions to the control panel 4-6 through the touch control display screen 1-6, and is usually set to automatically collect excrement every three hours. The drying box 4-4-6 is placed directly below the water-absorbing filter cloth 4-4-7 to absorb urine discharged by the animals in the incubator and excess moisture in the environment. The drying box 4-4-6 can be filled with bagged quicklime particles or sealed silicon dioxide crystals.

[0072] For further information, see Figure 2 and Figure 3 The lighting assembly 6 is composed of an aluminum substrate and an LED light source, and is divided into three light source panels, which are respectively fixed to the front, back and right side of the inner cavity of the portable suitcase 1. The power supply line of the lighting assembly 6 is connected to the rechargeable battery assembly connector, and its control signal line is connected to the touch control display screen 1-6; the light intensity, color temperature and switch signal of the lighting assembly can be controlled by the touch control display screen 1-6.

[0073] The camera monitoring and visual information processing module 5 is placed at the rightmost end of the suitcase body 1, facing the transparent acrylic observation surface of the animal culture module 4, for real-time monitoring of the cultured animals. A common industrial camera on the market can be selected according to the size of the internal space and the required functions. The camera is fixed on the bracket and fixed inside the suitcase body through the bracket. The electrical connector of the camera is connected to the rechargeable battery pack, and the signal line is connected to the control panel. The pixel and clarity of the camera can be adjusted through the touch display screen.

[0074] Furthermore, a gas booster pump 2-9 is fixed on the outside of the module housing 2-1, and one end of the gas booster pump 2-9 is connected to the air inlet 2-2 of the oxygen replacement module, and the other end is connected to the air outlet 4-1-3 of the culture module. After the booster pump 2-9 is started, a pressure difference is formed inside and outside the incubator and the oxygen replacement device, and the water vapor, carbon dioxide, ammonia and other harmful gases discharged from the animal culture module are discharged from the air outlet of the incubator through the booster pump to the oxygen replacement and ammonia treatment device. These discharged gases first absorb excess water vapor through the desiccant layer, and the remaining gas then absorbs ammonia and other harmful gases through the polymer activated carbon and molecular sieve ammonia adsorbent layer. Finally, the remaining carbon dioxide reacts with potassium superoxide to produce oxygen, which is passed through the air outlet to the inside of the incubator to form an air circulation loop. The user can calculate the amount of consumables required according to the animal volume and transportation time, and open the upper cover to replace them after use.

[0075] Furthermore, the sensor and temperature control component 4-5 are fixedly installed inside the animal culture module box 4-1, including a temperature and humidity sensor, a gas sensor and a heating device; the probe of the gas sensor collects data on the concentration of gases such as carbon dioxide, ammonia, and oxygen; the temperature and humidity sensor and the gas sensor send the data to the touch control display screen 1-6. When the sensor detects that the temperature in the incubator is too low or too high, the touch control display screen 1-6 sends a command to the control board 4-6 in the incubator, and the temperature control module starts working to control the temperature in the incubator to the most comfortable state for the small animal's body surface.

[0076] In this embodiment, during the entire animal culture module air duct design process, it is necessary to focus on whether the air circulation loop of the air duct is smooth and whether there is turbulence. Secondly, it is also necessary to focus on monitoring the wind speed at the location of the animal in the feeding cage and the wind speed at the location of the waste collection device. According to the "GB 14925-2023 Experimental Animal Environment and Facilities" standard, the most suitable wind speed for the surface of experimental animals in the feeding cage is 0.2-0.3m / s. By consulting relevant papers and documents, the wind speed required for the fan to blow excrement to the waste collection device is 0.3-0.4m / s.

[0077] Two 4010 axial fans are installed side by side on the top surface of the air duct. The internal air duct of the culture module is simulated and analyzed based on the CFD finite element method. The air circulation cloud diagram inside the incubator is shown as follows: Fig.12 As shown in Figure 2, the wind speed at the monitoring point is Fig.13 The air velocity in the cage is 0.069m / s, the air velocity on the left side of the waste collection device is 0.165m / s, and the air velocity on the right side of the waste collection device is 0.137m / s. Fig.12 Circulation loop analysis shows that when two fans are installed side by side, air turbulence occurs, which does not meet the design requirements.

[0078] Two 4010 axial fans are staggered on the top of the air duct. The internal air duct of the culture module is simulated and analyzed based on the CFD finite element method. The air circulation cloud diagram inside the incubator is shown as follows: Fig.14 As shown in Figure 2, the wind speed at the monitoring point is Fig.15 The air velocity in the cage is 0.11m / S, the air velocity on the left side of the waste collection device is 0.162m / S, and the air velocity on the right side of the waste collection device is 0.084m / S. Using two staggered 4010 axial flow fans will not form air turbulence, but the air velocity cannot reach the optimal level.

[0079] Based on the above analysis, a fan with larger air volume and air pressure is selected, and two 6010 axial flow fans are installed staggered on the top surface of the air duct. Based on the CFD finite element method, the internal air duct of the culture module is simulated and analyzed. The air circulation cloud diagram inside the incubator is as follows Fig.16 As shown in Figure 2, the wind speed at the monitoring point is Fig.17 As shown. The entire air circuit is very smooth, forming a closed circulation loop, and there is no air turbulence between the fans. The air flow rate in the breeding cage is 0.355m / s, the air flow rate on the left side of the waste collection device is 0.496m / s, and the air flow rate on the right side of the waste collection device is 0.595m / s, which meets the design requirements.
