Description

Technical Field

[0001] This invention relates to the field of animal husbandry and veterinary disease prevention equipment technology, and in particular to a disease prevention isolation cage for animal husbandry and veterinary use. Background Technology

[0002] In sheep and cattle breeding and veterinary treatment, lambs and calves, due to their young age and relatively weak resistance, usually need to be isolated and observed separately when weaned, transferred to other groups, transported, during purchase quarantine, or when they show suspected symptoms such as diarrhea, cough, or fever. This is to reduce the risk of disease transmission among young animals in the same group. Currently, farms or veterinary stations mostly use ordinary fences, simple cages, or individual isolation pens to isolate lambs and calves. Their main function is to limit the range of movement of young animals and prevent them from direct contact with healthy livestock.

[0003] However, calves and lambs continue to excrete feces and urine and produce respiratory exhaust gases during isolation, easily leading to increased levels of ammonia, carbon dioxide, humidity, and suspended particulate matter in the cages. This is especially true in relatively enclosed spaces or with insufficient ventilation, creating an environment conducive to the spread of pathogens. Existing isolation devices typically lack zoned air monitoring in the animal's breathing areas and areas contaminated by feces, making it impossible to promptly determine the source of contamination within the cages and the risk of airborne transmission.

[0004] Meanwhile, the health status of calves and cattle largely depends on manual observation by veterinarians or livestock handlers, such as observing their body temperature, activity level, lying position, feeding and drinking habits, coughing, or unusual vocalizations. This method not only requires personnel to frequently approach the isolation cage but also easily leads to delays in detecting abnormalities due to long observation intervals. For young animals suspected of having infectious diseases, frequent opening of the cage for inspection or manual spraying of disinfectant may also increase the risk of pathogen spillover and cross-infection.

[0005] Furthermore, existing disinfection methods for isolation cages mostly involve timed manual spraying or overall atomization disinfection. These methods cannot be tailored to the location of calves or cattle, the level of fecal contamination, or changes in air quality, leading to insufficient disinfection in heavily contaminated areas and over-disinfection in uncontaminated areas. After disinfection, existing equipment typically lacks re-inspection and feedback adjustment mechanisms, making it impossible to confirm whether the air quality inside the cage has returned to a safe level. Therefore, there is an urgent need for a livestock and veterinary quarantine cage that can integrate air quality, the condition of young animals, and the disinfection process for coordinated control. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a disease prevention and isolation cage for animal husbandry and veterinary medicine.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a livestock and veterinary disease prevention isolation cage, comprising an isolation cage body, a sealed cage door disposed on the front side of the isolation cage body, a supporting bottom plate disposed on the bottom of the isolation cage body, and a sludge collection chamber located below the supporting bottom plate, wherein an animal activity chamber is formed within the isolation cage body, and further comprising a disease prevention control system connected to the isolation cage body. An air circulation channel is provided at the upper end of the animal activity chamber, and a sterilization component is provided in the air circulation channel. An atomizing disinfection component is provided in the animal activity chamber and the waste collection chamber. The epidemic prevention and control system includes an air quality monitoring module, an animal status monitoring module, a risk assessment module, a disinfection and sterilization execution module, and a control host. The air quality monitoring module is used to collect air quality parameters inside the cage; The animal status monitoring module is located inside the isolation cage and is used to collect vital signs and behavioral status parameters of the isolated animals. The disinfection and sterilization execution module is connected to the atomizing disinfection component and the sterilization component respectively, and is used to drive the atomizing disinfection component and the sterilization component to perform disinfection and sterilization operations; The control host is electrically connected to the air quality monitoring module, animal status monitoring module, risk assessment module, and disinfection and sterilization execution module, respectively. The control host is used to generate a pathogen spread risk level based on the air quality parameters, vital sign parameters, and behavioral status parameters, and to control the atomizing disinfection component and sterilization component to perform disinfection and sterilization operations of corresponding intensity and corresponding area based on the pathogen spread risk level.

[0008] As a further embodiment of the present invention, the air circulation channel has a return air inlet and an air outlet communicating with the animal activity cavity, and the air circulation channel is provided with a filter component, the sterilization component and the circulating fan in sequence along the airflow direction inside the air circulation channel; The air quality monitoring module includes a first air detection unit and a second air detection unit. The first air detection unit is located in the respiratory monitoring area near the upper part of the animal activity cavity, and the second air detection unit is located in the fecal pollution area near the sludge collection cavity, so as to detect the air status in the animal respiratory area and the fecal pollution area respectively.

[0009] As a further embodiment of the present invention, the atomizing disinfection assembly includes a top atomizing nozzle group disposed at the top of the animal activity chamber, a door area atomizing nozzle group disposed inside the sealed cage door, and a fecal area atomizing nozzle group disposed above the sludge collection chamber. The animal status monitoring module includes an infrared temperature measurement unit, an image acquisition unit, a sound acquisition unit, and a load detection unit. The infrared temperature measurement unit and the image acquisition unit are located on the top of the isolation cage body, the sound acquisition unit is located on the side wall of the isolation cage body, and the load detection unit is located below the load base plate, used to detect the animal's position and activity level. The control host can control at least one of the top atomizing nozzle group, the gate area atomizing nozzle group, and the feces and sewage area atomizing nozzle group to perform zoned atomizing disinfection according to the animal's position.

[0010] As a further aspect of the present invention, the air quality parameters collected by the air quality monitoring module include at least two of the following: ammonia concentration, carbon dioxide concentration, temperature, humidity, and particulate matter concentration. The risk assessment module is used to generate an air pollution index based on the air quality parameters, and to determine whether the air transmission conditions inside the cage meet the preset risk conditions based on the air pollution index.

[0011] As a further aspect of the present invention, the vital signs and behavioral parameters collected by the animal status monitoring module include at least two of the following: body temperature, activity level, resting duration, frequency of coughing, abnormal vocalizations, respiratory rate, feeding frequency, and drinking frequency. The risk assessment module is used to generate an animal abnormality index based on the vital signs parameters and behavioral status parameters, and to fuse the animal abnormality index with the air pollution index to generate the pathogen spread risk level.

[0012] As a further aspect of the present invention, the pathogen spread risk level includes a low risk level, a medium risk level, and a high risk level. When the pathogen spread risk level is a low risk level, the control host controls the circulating fan to operate at a first air volume and controls the atomizing disinfection component to perform low-intensity atomizing disinfection according to a first disinfection duration. When the pathogen spread risk level is medium risk level, the control host controls the circulating fan to run at the second air volume, and controls the atomizing disinfection component to perform local disinfection on the atomizing nozzle group in the door area or the atomizing nozzle group in the fecal sewage area. When the pathogen spread risk level is high, the control host controls the circulating fan to run at the third air volume, and controls the sterilization component and at least two atomizing nozzle groups to perform disinfection and sterilization operations simultaneously. Wherein, the third air volume is greater than the second air volume, and the second air volume is greater than the first air volume.

[0013] As a further aspect of the present invention, the control host includes a closed-loop feedback control unit, which is used to control the air quality monitoring module to collect the air quality parameters in the cage again after the disinfection and sterilization execution module completes a disinfection and sterilization operation. When the air quality parameters collected again do not drop to the preset safe range, the closed-loop feedback control unit increases the operating air volume of the circulating fan, extends the sterilization time of the sterilization component, or increases the spraying time of the atomizing disinfection component. When the air quality parameters collected again drop to a preset safe range, the closed-loop feedback control unit controls the disinfection and sterilization execution module to stop or resume the normal disinfection mode.

[0014] As a further aspect of the present invention, the epidemic prevention and control system further includes an alarm recording module, which is electrically connected to the control host and is used to record air quality parameters, vital sign parameters, behavioral status parameters, pathogen spread risk level, disinfection and sterilization execution records, and abnormal alarm records. The epidemic prevention and control system also includes a door lock assembly, which is located at the sealed cage door and electrically connected to the control host. When the pathogen spread risk level reaches the preset high risk level, or when the air quality parameters and animal abnormality index do not decrease within a preset time, the control host controls the alarm recording module to issue an alarm signal and controls the door lock assembly to restrict the opening of the sealed cage door or prompt for manual handling.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. This invention, by equipping isolation cages with air quality monitoring, animal condition monitoring, and risk assessment functions, can simultaneously acquire information on changes in the cage environment and the health status of young animals. The system can comprehensively determine the risk level of pathogen spread based on air parameters such as ammonia, carbon dioxide, humidity, and particulate matter, combined with animal condition parameters such as body temperature, activity level, resting time, coughing sounds, and feeding and drinking behavior. Compared to traditional isolation methods that rely solely on manual observation and experience, this invention can more promptly detect abnormal conditions in calves and sheep during isolation, reducing the need for frequent close-range inspections or opening of cages, thereby lowering the risk of cross-infection in young animals and the spread of pathogens by personnel, and improving the continuity and accuracy of isolation observation.

[0016] 2. This invention enables coordinated control of air circulation, sterilization, and atomized disinfection based on the pathogen spread risk level. When the risk is low, basic ventilation and low-intensity disinfection can be maintained. When there is a risk of contamination in the manure-contaminated area or cage door area, the corresponding atomized nozzle group can be activated for localized treatment. When the risk is high, the circulating fan, sterilization components, and multiple atomized nozzle groups can be coordinated to perform enhanced disinfection. After disinfection, the system can collect air quality parameters again and adjust the airflow, sterilization duration, or spray duration based on the re-inspection results, thus forming a closed-loop epidemic prevention process of detection, treatment, and re-inspection. This method avoids the waste of disinfectant and irritation to young animals caused by traditional overall spraying, while improving the epidemic prevention treatment effect in key areas such as manure-contaminated areas, cage door areas, and air circulation channels.

[0019] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] Please see Figure 1 and Figure 2 The present invention provides a technical solution: a disease prevention isolation cage for animal husbandry and veterinary medicine, including an isolation cage body 1, a sealed cage door 2 disposed on the front side of the isolation cage body 1, a supporting bottom plate 3 disposed on the bottom of the isolation cage body 1, and a sludge collection chamber 4 located below the supporting bottom plate 3. An animal activity chamber 5 is formed inside the isolation cage body 1, and a disease prevention control system 6 connected to the isolation cage body 1 is also included. An air circulation channel 7 is provided at the upper end of the animal activity chamber 5, and a sterilization component 8 is provided in the air circulation channel 7. An atomizing disinfection component 9 is provided in the animal activity chamber 5 and the sludge collection chamber 4. The epidemic prevention and control system 6 includes an air quality monitoring module, an animal status monitoring module, a risk assessment module, a disinfection and sterilization execution module, and a control host. The air quality monitoring module is used to collect air quality parameters inside the cage; The animal status monitoring module is installed inside the isolation cage body 1 and is used to collect vital signs and behavioral status parameters of the isolated animals. The disinfection and sterilization execution module is connected to the atomizing disinfection component 9 and the sterilization component 8 respectively, and is used to drive the atomizing disinfection component 9 and the sterilization component 8 to perform disinfection and sterilization operations; The control host is electrically connected to the air quality monitoring module, animal status monitoring module, risk assessment module, and disinfection and sterilization execution module, respectively. The control host is used to generate pathogen spread risk level based on air quality parameters, vital sign parameters, and behavioral status parameters, and to control the atomizing disinfection component 9 and sterilization component 8 to perform disinfection and sterilization operations of corresponding intensity and corresponding area according to the pathogen spread risk level.

[0021] Specifically, the isolation cage body 1 can be formed by combining a stainless steel frame and a transparent observation panel. The sealed cage door 2 is fitted to the front of the cage body with a sealing strip to reduce the direct leakage of untreated air from the cage. The supporting base plate 3 is preferably a detachable plate with a non-slip surface, and the sludge collection chamber 4 below it is used to receive animal excrement, rinsing fluid, and disinfectant residue. The epidemic prevention and control system 6 can be installed on the side wall or back of the isolation cage body 1 in the form of an external control box. The control box contains a control host, a power supply unit, and a communication interface. Each monitoring module and execution component is connected to the control host via cable or wireless means. During operation, the control host no longer simply starts disinfection at fixed times, but simultaneously receives information on the air status inside the cage and the health status of the animals. It uses both environmental pollution and abnormal animal behavior as a basis for judgment, and then selects different disinfection areas and disinfection intensities, transforming the isolation cage from an ordinary containment device into an intelligent isolation device that can actively identify risks and perform epidemic prevention and control measures.

[0022] As a further embodiment of the present invention, the air circulation channel 7 has a return air inlet and an air outlet communicating with the animal activity chamber 5, and the air circulation channel 7 is provided with a filter assembly 10, a sterilization assembly 8 and a circulating fan 11 arranged sequentially along the airflow direction. The air quality monitoring module includes a first air detection unit and a second air detection unit. The first air detection unit is located in the respiratory monitoring area near the upper part of the animal activity chamber 5, and the second air detection unit is located in the fecal pollution area near the sewage collection chamber 4, so as to detect the air status in the animal respiratory area and the fecal pollution area respectively.

[0023] Furthermore, the air circulation channel 7 can be arranged laterally along the top of the animal activity chamber 5, with the return air vent located near one side or the rear of the animal activity chamber 5, and the air outlet facing the upper part or upper side of the animal activity chamber 5. This creates a circulation path for the air inside the cage, from the animal activity area into the air circulation channel 7, through purification and sterilization, and back into the cage. The filter assembly 10 can be one or more combinations of replaceable filters, activated carbon layers, or high-efficiency filter layers to intercept dander, dust, droplets, and odorous gases. The sterilization assembly 8 can be an ultraviolet germicidal lamp, a plasma sterilizer, or a photocatalytic sterilizer, and the circulating fan 11 provides a stable airflow. The first air detection unit is located near the animal's breathing height to easily reflect the quality of the air inhaled by the animal; the second air detection unit is located near the sludge collection chamber 4 to easily reflect the volatile pollution from feces. Through upper and lower zone detection, the control unit can distinguish whether the source of pollution is deterioration of the air in the animal's breathing area or increased pollution in the feces area, thus avoiding the use of the same treatment method for all abnormalities.

[0024] As a further embodiment of the present invention, the atomizing disinfection assembly 9 includes a top atomizing nozzle assembly disposed at the top of the animal activity chamber 5, a door area atomizing nozzle assembly disposed inside the sealed cage door 2, and a fecal area atomizing nozzle assembly disposed above the sludge collection chamber 4. The animal status monitoring module includes an infrared temperature measurement unit, an image acquisition unit, an audio acquisition unit, and a load detection unit. The infrared temperature measurement unit and the image acquisition unit are located on the top of the isolation cage body 1, the audio acquisition unit is located on the side wall of the isolation cage body 1, and the load detection unit is located below the load base plate 3 to detect the animal's position and activity level. The control unit can control at least one of the top atomizing nozzle group, the gate area atomizing nozzle group, and the feces and sewage area atomizing nozzle group to carry out zoned atomizing disinfection according to the animal's position.

[0025] Furthermore, the atomizing disinfection component 9 can be composed of a disinfectant tank, a micro pump, infusion lines, and multiple nozzle groups, each individually controlled by a solenoid valve. The top atomizing nozzle group is suitable for low-dose atomization treatment of the air above the animal activity chamber 5 and the overall environment inside the cage; the door area atomizing nozzle group is suitable for local disinfection of the area near the door seam, the operation contact area, and the animal's entry and exit path before and after the sealed cage door 2 is opened; the feces and sludge area atomizing nozzle group is suitable for enhanced disinfection of highly polluted areas near the sludge collection chamber 4. The infrared temperature measurement unit can be used for non-contact detection of animal body surface temperature, the image acquisition unit can identify the area where the animal stays, changes in lying posture, and activity frequency, the sound acquisition unit can collect coughing, wheezing, or abnormal sounds, and the load detection unit can use a weighing sensor or pressure distribution sensor to determine the animal's position. When an animal stays near the cage door or above the sludge collection chamber for a long time, the control host can prioritize activating the nozzle group in the corresponding area, thereby achieving targeted disinfection of high-contact areas, high-pollution areas, or areas where animals gather, reducing unnecessary stimulation to animals caused by whole-cage spraying.

[0026] As a further aspect of the present invention, the air quality parameters collected by the air quality monitoring module include at least two of the following: ammonia concentration, carbon dioxide concentration, temperature, humidity, and particulate matter concentration. The risk assessment module is used to generate an air pollution index based on air quality parameters, and to determine whether the air transmission conditions inside the cage meet the preset risk conditions based on the air pollution index.

[0027] Furthermore, air quality parameters can be selected based on different livestock species, cage sizes, and rearing environments. For example, when isolating small animals such as dogs and cats, temperature, humidity, carbon dioxide concentration, and particulate matter concentration can be prioritized; when isolating livestock such as pigs, sheep, and poultry, ammonia concentration can be further monitored to promptly detect increases in irritating gases caused by the volatilization of feces. The risk assessment module can compare each parameter with preset thresholds and assign different weights based on the degree of exceedance. For example, excessively high humidity and increased particulate matter concentration indicate enhanced aerosol transmission conditions; increased ammonia concentration indicates an increased risk of fecal contamination; and increased carbon dioxide concentration indicates an increased risk of insufficient ventilation. The air pollution index can be obtained through weighted summation, hierarchical judgment, or table lookup, without limiting the specific algorithm. In this way, the system can expand from single-indicator alarms to comprehensive judgment of airborne transmission conditions, improving the accuracy of identifying pathogen diffusion environments.

[0028] As a further aspect of the present invention, the vital signs and behavioral parameters collected by the animal status monitoring module include at least two of the following: body temperature, activity level, resting duration, frequency of coughing, abnormal vocalizations, respiratory rate, feeding frequency, and drinking frequency. The risk assessment module is used to generate an animal abnormality index based on vital sign parameters and behavioral status parameters, and then integrates the animal abnormality index with the air pollution index to generate a pathogen spread risk level.

[0029] Furthermore, the data collected by the animal condition monitoring module can be used to determine whether animals exhibit suspected disease symptoms such as fever, lethargy, abnormal breathing, or decreased feed intake. Elevated body temperature detected by the infrared thermometer can be considered a factor of abnormal vital signs; a significant decrease in activity, prolonged lying down, or frequent changes in posture detected by the image acquisition unit can be considered a factor of abnormal behavior; persistent coughing, wheezing, or abnormal vocalizations detected by the sound acquisition unit can be considered a factor of respiratory abnormalities; feeding and drinking frequencies can be obtained through changes in feed trough weight, water flow rate, or image recognition. The risk assessment module combines these abnormal animal factors with the air pollution index, which can avoid misjudging high risk based solely on short-term fluctuations in air quality indicators. It can also proactively raise the risk level when abnormal animal behavior has already occurred before air quality indicators have significantly deteriorated, thus enabling a preemptive assessment of the risk of pathogen spread.

[0030] As a further aspect of the present invention, the pathogen spread risk level includes low risk level, medium risk level and high risk level. When the pathogen spread risk level is low risk level, the control host controls the circulating fan 11 to run at a first air volume and controls the atomizing disinfection component 9 to perform low-intensity atomizing disinfection according to a first disinfection duration. When the risk level of pathogen spread is medium risk, the control host controls the circulating fan 11 to run at the second air volume, and controls the atomizing disinfection component 9 to perform local disinfection on the atomizing nozzle group in the door area or the atomizing nozzle group in the fecal sewage area. When the pathogen spread risk level is high, the control host controls the circulating fan 11 to run at the third air volume, and controls the sterilization component 8 and at least two atomizing nozzle groups to perform disinfection and sterilization operations simultaneously. Among them, the third air volume is greater than the second air volume, and the second air volume is greater than the first air volume.

[0031] Furthermore, different control strategies correspond to different pathogen spread risk levels. Low risk levels can be understood as animals being in basically normal condition and air quality being within acceptable limits; in this case, the system primarily focuses on maintaining air circulation and minimal preventative disinfection. Medium risk levels can be understood as air pollution index or animal abnormality index showing a certain increase; in this case, the system prioritizes local disinfection of potentially contaminated areas such as the entrance area or fecal area, and increases air circulation speed. High risk levels can be understood as animal abnormalities and airborne transmission conditions simultaneously worsening; in this case, the system activates higher airflow, longer sterilization time, and combined treatment with two or more nozzle groups. The first, second, and third airflow rates can be pre-calibrated based on the cage volume or dynamically adjusted by the control unit according to air quality trends. Through tiered control, the system can achieve a balance between disease prevention effectiveness, animal comfort, and disinfectant consumption, avoiding the problems of traditional isolation cages requiring manual judgment and disinfection.

[0032] As a further aspect of the present invention, the control host includes a closed-loop feedback control unit, which is used to control the air quality monitoring module to collect the air quality parameters in the cage again after the disinfection and sterilization execution module completes a disinfection and sterilization operation. When the air quality parameters collected again do not drop to the preset safe range, the closed-loop feedback control unit increases the operating air volume of the circulating fan 11, extends the sterilization time of the sterilization component 8, or increases the spraying time of the atomizing disinfection component 9. When the air quality parameters collected again drop to the preset safe range, the closed-loop feedback control unit controls the disinfection and sterilization execution module to stop or resume the normal disinfection mode.

[0033] Furthermore, the closed-loop feedback control unit is used to determine whether the disinfection and sterilization measures have achieved the expected results. For example, after completing atomized disinfection and duct sterilization, the system delays for a preset time to collect air quality parameters again to avoid misjudgment caused by a short-term increase in humidity immediately after spraying. If the re-inspection results show that the particulate matter concentration, ammonia concentration, or humidity is still within the abnormal range, the closed-loop feedback control unit can select the processing method according to the type of abnormality: when the particulate matter concentration or carbon dioxide concentration is high, the air volume of the circulating fan 11 is increased first; when the pollution index in the air circulation channel 7 is consistently high, the working time of the sterilization component 8 is extended; when the pollution near the collection chamber 4 is still obvious, the spraying time of the atomized disinfection component 9 is increased. If the re-inspection results return to the safe range, the system stops the enhanced processing and enters the regular monitoring state. This closed-loop process enables the isolation cage to have the function of "post-treatment verification," rather than just performing a fixed disinfection action once.

[0034] As a further embodiment of the present invention, the epidemic prevention and control system also includes an alarm recording module, which is electrically connected to the control host and is used to record air quality parameters, vital sign parameters, behavioral status parameters, pathogen spread risk level, disinfection and sterilization execution records, and abnormal alarm records. The epidemic prevention and control system 6 also includes a door lock assembly, which is located at the sealed cage door 2 and electrically connected to the control host. When the risk level of pathogen spread reaches the preset high risk level, or when the air quality parameters and animal abnormality index do not decrease within a preset time, the control host controls the alarm recording module to send an alarm signal and controls the door lock component to restrict the opening of the sealed cage door 2 or prompts for manual handling.

[0035] Furthermore, the alarm recording module may include a local audible and visual alarm, a display screen, a memory, and a communication module. The display screen can show the current air quality status, animal abnormal status, risk level, and disinfection execution status. The memory is used to generate epidemic prevention records during the isolation period. The door lock component can be a combination of an electric lock, electromagnetic lock, or mechanical lock and an electric actuator. It is installed on the door frame or door body of the sealed cage door 2 and locks or unlocks under the command of the control host. When the system determines that the risk of pathogen spread is high, or when the air quality parameters and animal abnormality index have not decreased after disinfection, the alarm recording module issues a prompt to the breeder or veterinarian. At the same time, the door lock component restricts unauthorized opening of the sealed cage door 2 to reduce the risk of pathogen leakage caused by personnel accidentally opening the cage door. The recorded content can also be uploaded to the management terminal via wireless communication for subsequent tracking of animal isolation time, abnormal occurrence time, disinfection frequency, and manual handling.

[0036] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
