Description

Technical Field

[0001] This invention relates to the field of laboratory pig parameter measurement technology, specifically to a comprehensive measurement device for multi-dimensional physiological parameters of laboratory pigs. Background Technology

[0002] In the field of large-scale farming, mature solutions have been developed for measuring the weight of pigs. Existing equipment is mainly divided into three categories: First, electronic scales, which achieve contact weighing through pressure sensors with an accuracy of 0.1 kg, but can only acquire weight data; second, ultrasonic weighing instruments, which perform non-contact estimation based on the principle of sound wave reflection, but are affected by body shape and body condition, with errors reaching several kilograms, and lack body size measurement function; and third, image recognition weighing systems, which estimate weight through contour analysis. Although they can record changes in body shape, the core algorithm is optimized for farming scenarios and cannot meet the requirements of accurate multi-dimensional body size measurement needed for experiments.

[0003] Meanwhile, experimental pigs are mostly miniature pigs, which have a huge weight difference from meat pigs. Miniature pigs generally weigh from tens of grams at birth to 40-60 kg, while meat pigs generally weigh 200-250 kg. Experimental pigs usually need to have their weight, body length, and other data collected monthly, weekly, or daily, depending on the requirements of the research project, while meat pigs generally do not have this requirement.

[0004] Traditional manual operation is still relied upon when measuring the body size of experimental pigs. This requires a combination of tools, including electronic scales for weighing, measuring rods for measuring body length, and soft measuring tapes for measuring body height. While small pigs can be measured by manually fixing them in place, this method is not suitable for medium-sized pigs. Generally, the experimental pigs are herded into a pen and restrained, and then measured manually. Body length, height, and leg length can be measured with slight contact, which is less likely to cause stress to the pigs. However, when measuring the chest and waist circumference of experimental pigs, the sensitive skin on the abdomen necessitates manually wrapping the measuring tape around the chest and abdomen. If the tape directly rubs or presses against the abdomen, or if the force applied is too great, it can stimulate nerve endings in the skin, causing the pigs to struggle and become agitated. The body measurement data is also subject to significant errors due to deviations in the measurement angle and misalignment of the measuring tape. Therefore, a comprehensive measurement device for multi-dimensional physiological parameters of experimental pigs is proposed to address these issues. Summary of the Invention

[0005] The purpose of this invention is to provide a comprehensive measurement device for multidimensional physiological parameters of experimental pigs, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: As an optional solution of the experimental pig multidimensional physiological parameter comprehensive measurement device described in this invention, the experimental pig multidimensional physiological parameter comprehensive measurement device includes a load-bearing platform, side guardrails and a scale adjustment measurement module. The load-bearing platform is equipped with parallel side railings on both sides. A ruler adjustment and measurement module is installed on the outside of one side railing, and a misaligned ruler movement module is installed on the top of the other side railing. The ruler adjustment and measurement module and the misaligned ruler movement module work together to measure the waist and chest circumference of the experimental pigs. The ruler adjustment and measurement module includes a box that is fixedly connected to the side guardrail. An upper unit moving plate is slidably connected to the top of the box. A second rotating device is fixedly connected to one end of the upper unit moving plate. A measuring ruler adjustment mechanism is fixedly connected to the movable end of the second rotating device. A measuring ruler is fixedly connected to the other side of the measuring ruler adjustment mechanism. The other end of the measuring ruler is connected to the misaligned ruler moving module. The lower unit moving plate is slidably connected to the lower part of the box, and a connecting plate is fixedly connected to the upper unit moving plate. The other end of the connecting plate is fixedly connected to the upper unit moving plate. The ruler adjustment and measurement module also includes three sets of wire take-up mechanisms. The first set of wire take-up mechanisms is installed inside the measuring ruler adjustment mechanism, the second set of wire take-up mechanisms is fixed above the lower unit moving plate, and the third set is located below the misaligned ruler moving module and is fixedly connected to the load-bearing platform. The movable ends of the three sets of wire take-up mechanisms are all fixedly connected to the measuring ruler.

[0007] As an optional embodiment of the multidimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, the misaligned ruler moving module includes a third rotating device installed above the side guardrail. The movable end of the third rotating device is fixedly connected to an arc-shaped misaligned plate, and the other end of the arc-shaped misaligned plate is equipped with an automatic ruler winding device for winding up the measuring ruler.

[0008] As an optional embodiment of the multi-dimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, a pushing mechanism fixedly connected to the load-bearing platform is also provided between the side guardrails. A movable baffle is fixedly connected to the free end of the pushing mechanism. A groove is provided on the inner side of the movable baffle. A feeding trough fixedly connected to the movable baffle is provided on one side of the groove. An integrated measurement module for detecting physiological parameters of experimental pigs is also installed on the top of the movable baffle. A movable baffle is also provided on one side of the side guardrail.

[0009] Traditional manual methods are still used when measuring the size of experimental pigs. This requires a combination of tools, including electronic scales for weighing, measuring rods for length, and measuring tapes for height. While small pigs can be measured by manually restraining them, this method is not suitable for medium-sized pigs. Generally, the pigs are herded into a pen and restrained, then measured manually. Length, height, and leg length can be measured with slight contact, minimizing stress. However, when measuring chest and waist circumference, the sensitive skin on the abdomen necessitates manually wrapping the measuring tape around the chest and abdomen. Direct friction or pressure from the tape on the abdomen, or excessive force, can irritate nerve endings and trigger reactions. The pigs' struggles and agitation, coupled with measurement angle deviations and ruler misalignment, resulted in significant errors in body measurement data. First, the experimental pigs were driven to the measurement area between the two side fences. Food was placed in a feeding trough on one side of a movable baffle to guide the pigs and stabilize their posture. The movable baffle, made of transparent acrylic, allowed the pigs to clearly observe their surroundings, effectively alleviating their anxiety. A pushing mechanism adjusted the baffle's position to accommodate the different body sizes of the pigs, ensuring they were in the measurement reference position. The ruler adjustment mechanism was then activated, moving the ruler to a position above the pig's torso. Simultaneously, the misaligned ruler movement module on the other side was activated, causing the ruler to move along a preset trajectory around the pig's chest or abdomen. This process significantly reduced direct human intervention. An integrated temperature and pressure detection unit on the ruler monitored the contact between the ruler and the pig's skin in real time, enabling automated and accurate measurement of chest and waist circumference parameters.

[0010] As an optional embodiment of the multidimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, a lifting mechanism is fixedly connected inside the box, a rotating plate is rotatably connected to the top of the lifting mechanism, and the other end of the rotating plate is rotatably connected to an inclined connecting plate.

[0011] As an optional embodiment of the multi-dimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, a guide column is slidably connected inside the connecting plate, and one end of the guide column is fixedly connected to the box body.

[0012] As an optional embodiment of the multi-dimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, a blower for heating air is also installed on one side of the connecting plate, a vertically arranged preheating pipe is installed on the top of the blower, and a uniformly distributed exhaust hole is opened on one side of the preheating pipe.

[0013] As an optional embodiment of the multidimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, the measuring ruler has uniformly distributed graduations on its outer side, and a limit baffle is provided at the zero graduation position on the surface of the measuring ruler.

[0014] As an optional embodiment of the multi-dimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, the surface of the measuring ruler is also equipped with a temperature and pressure integrated detection unit that integrates a temperature sensing mechanism and a pressure sensing mechanism, used to determine whether it is in contact with the skin of the experimental pig.

[0015] Low-stress contact design and measurement reliability assurance: Before measurement, the blower is turned on to heat the air. The hot air is discharged through the exhaust hole on the side wall of the preheating tube to preheat the measuring ruler that will be in contact with the skin of the experimental pig's abdomen. This reduces the temperature difference between the ruler and the skin, thereby reducing the probability of stress response in the experimental pig. The aforementioned integrated temperature and pressure detection unit can provide real-time feedback of pressure data to ensure that the measuring ruler is in close contact with the pig's skin without excessive pressure. This ensures the accuracy of the measurement data while avoiding physiological discomfort to the experimental pig.

[0016] As an optional embodiment of the multi-dimensional physiological parameter comprehensive measurement device for experimental pigs described in this invention, the measuring scale adjustment mechanism includes a rotating frame fixedly connected to a second rotating device, the other end of the rotating frame being fixedly connected to the measuring scale, a wire take-up mechanism and a first rotating device being installed on the inner side of the rotating frame, an adaptive arc-shaped telescopic component being fixedly connected to the movable end of the first rotating device, a protective cover being fixedly connected to the other end of the adaptive arc-shaped telescopic component, and a rotating wheel being rotatably connected to the inner side of the protective cover.

[0017] Ruler-like circumferential drive and misaligned anti-collision design: During the ruler's circumference, the first rotating device drives the adaptive arc-shaped telescopic component to rotate, causing the protective cover and rotating wheel at its end to move synchronously. The rotating wheel abuts against one end of the ruler and slowly moves along the ruler's extension direction to the limiting baffle, where it connects and closes with the ruler on the misaligned ruler moving module side, forming a closed measurement loop around the pig's body, facilitating accurate data reading. The ruler adjustment mechanism and the misaligned ruler moving module adopt a misaligned layout design, which can effectively avoid collision interference between the two during movement. Compared with the vertical plane deviation problem that is prone to occur when manually circumferentially rotating the ruler, the misaligned drive structure of this device can ensure the verticality of the measurement plane, further improving the measurement accuracy of chest and waist circumference data.

[0018] Compared with the prior art, the beneficial effects of the present invention are: Pre-measurement restraint and stress relief: First, the experimental pigs were driven to the measurement area between the two side fences. Food was placed in the feeding trough on one side of the movable baffle to guide the experimental pigs to stabilize their posture. The movable baffle was made of transparent acrylic sheet, which allowed the experimental pigs to clearly observe the surrounding environment and effectively relieve their tension. The movable baffle was adjusted in position by a pushing mechanism to adapt to the restraint requirements of experimental pigs of different sizes and ensure that the experimental pigs were in the measurement reference position.

[0019] Automated surround measurement and precision control: The measuring ruler adjustment mechanism is activated, driving the measuring ruler to a position above the experimental pig's torso; simultaneously, the offset ruler movement module on the other side is activated, causing the measuring ruler to circle the experimental pig's chest or abdominal area along a preset trajectory. This process significantly reduces direct human intervention. Through the integrated temperature and pressure detection unit integrated into the measuring ruler, the degree of contact between the ruler and the pig's skin is detected in real time, achieving automated and precise measurement of chest and waist circumference parameters.

[0020] Low-stress contact design and measurement reliability assurance: Before measurement, the blower is turned on to heat the air. The hot air is discharged through the exhaust hole on the side wall of the preheating tube to preheat the measuring ruler that will be in contact with the skin of the experimental pig's abdomen. This reduces the temperature difference between the ruler and the skin, thereby reducing the probability of stress response in the experimental pig. The aforementioned integrated temperature and pressure detection unit can provide real-time feedback of pressure data to ensure that the measuring ruler is in close contact with the pig's skin without excessive pressure. This ensures the accuracy of the measurement data while avoiding physiological discomfort to the experimental pig.

[0021] Ruler-like circumferential drive and misaligned anti-collision design: During the ruler's circumference, the first rotating device drives the adaptive arc-shaped telescopic component to rotate, causing the protective cover and rotating wheel at its end to move synchronously. The rotating wheel abuts against one end of the ruler and slowly moves along the ruler's extension direction to the limiting baffle, where it connects and closes with the ruler on the misaligned ruler moving module side, forming a closed measurement loop around the pig's body, facilitating accurate data reading. The ruler adjustment mechanism and the misaligned ruler moving module adopt a misaligned layout design, which can effectively avoid collision interference between the two during movement. Compared with the vertical plane deviation problem that is prone to occur when manually circumferentially rotating the ruler, the misaligned drive structure of this device can ensure the verticality of the measurement plane, further improving the measurement accuracy of chest and waist circumference data.

[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a technical solution: A comprehensive measurement device for multidimensional physiological parameters of experimental pigs includes a load-bearing platform 1, a side guardrail 2, and a scale adjustment and measurement module 7; The load-bearing platform 1 is equipped with parallel side rails 2 on both sides above it. A ruler adjustment and measurement module 7 is installed on the outside of one side rail 2, and a misaligned ruler movement module 8 is installed on the top of the other side rail 2. The ruler adjustment and measurement module 7 and the misaligned ruler movement module 8 are used together to measure the waist circumference and chest circumference of the experimental pigs. The ruler adjustment and measurement module 7 includes a box 701 fixedly connected to the side guardrail 2. The top of the box 701 is slidably connected to an upper unit moving plate 702. One end of the upper unit moving plate 702 is fixedly connected to a second rotating device 713. The movable end of the second rotating device 713 is fixedly connected to a measuring ruler adjustment mechanism 704. The other side of the measuring ruler adjustment mechanism 704 is fixedly connected to a measuring ruler 705. The other end of the measuring ruler 705 is connected to a misaligned ruler moving module 8. The lower unit moving plate 703 is slidably connected to the lower part of the housing 701. A connecting plate 706 is fixedly connected to the upper part of the lower unit moving plate 703. The other end of the connecting plate 706 is fixedly connected to the upper unit moving plate 702. The ruler adjustment and measurement module 7 also includes three sets of wire take-up mechanisms 712. The first set of wire take-up mechanisms 712 is installed inside the measuring ruler adjustment mechanism 704. The second set of wire take-up mechanisms 712 is fixed above the lower unit moving plate 703. The third set is located below the misaligned ruler moving module 8 and is fixedly connected to the load-bearing platform 1. The movable ends of the three sets of wire take-up mechanisms 712 are all fixedly connected to the measuring ruler 705.

[0025] A pushing mechanism 6 is fixedly connected to the load-bearing platform 1 between the side guardrails 2. A movable baffle 3 is fixedly connected to the free end of the pushing mechanism 6. A groove is opened on the inner side of the movable baffle 3. A feeding trough 5 is fixedly connected to the movable baffle 3 on one side of the groove. An integrated measurement module 4 for detecting physiological parameters of experimental pigs is also installed on the top of the movable baffle 3. The integrated measurement module 4 has a built-in sound unit that can soothe the experimental pigs by emitting low-frequency sounds (such as snoring). A movable baffle is also provided on one side of the side guardrail 2.

[0026] The surface of the measuring ruler 705 is also equipped with an integrated temperature and pressure detection unit 714, which integrates temperature and pressure sensing mechanisms, to determine whether it comes into contact with the skin of the experimental pig.

[0027] The misaligned ruler moving module 8 includes a third rotating device 801 installed above the side guardrail 2. The movable end of the third rotating device 801 is fixedly connected to an arc-shaped misaligned plate 802. The other end of the arc-shaped misaligned plate 802 is equipped with an automatic ruler winding device 803 for winding up the measuring ruler 705.

[0028] Traditional manual operation is still relied upon when measuring the size of experimental pigs. This requires a combination of tools, including electronic scales for weighing, measuring rods for length, and measuring tapes for height. While small pigs can be measured by manually restraining them, this method is unsuitable for medium-sized pigs. Generally, the pigs are herded into a pen and restrained, then measured manually. Length, height, and leg length can be measured with slight contact, minimizing stress. However, when measuring chest and waist circumference, the sensitive skin of the pig's abdomen necessitates manually wrapping the measuring tape around the chest and abdomen. Direct friction or pressure from the tape on the abdomen, or excessive force, can irritate nerve endings, causing the pig to struggle and become agitated. Measurements are also affected by angle deviations and tape misalignment. To address the issue of significant errors in body size data, the experimental pigs were first herded into the measurement area between the two side fences 2. Food was placed in the feeding trough 5 on one side of the movable baffle 3 to guide the pigs and stabilize their posture. Simultaneously, the movable baffle 3 was installed on the other side of the fence 2 to restrict the pigs' movement. The movable baffle 3, made of transparent acrylic, allowed the pigs to clearly observe their surroundings, effectively alleviating their anxiety. The movable baffle 3 was adjusted by the pushing mechanism 6 to accommodate the limiting needs of pigs of different sizes, ensuring that the pigs were in the measurement reference position. The measuring ruler adjustment mechanism 704 was activated, driving the measuring ruler 705 to move above the pig's torso. Simultaneously, the misaligned ruler movement module 8 on the other side was activated, causing the measuring ruler 705 to circle the pig's chest or abdomen along a preset trajectory. This process significantly reduced direct human intervention. The temperature and pressure integrated detection unit 714, integrated into the measuring ruler 705, detected the degree of contact between the ruler and the pig's skin in real time, achieving automated and accurate measurement of chest and waist circumference parameters. Also includes the following: The measuring ruler 705 preferably uses a flexible silicone tape. When measuring the chest circumference of experimental pigs, the pigs are moved above the load-bearing platform 1. Under the action of the movable baffle 3, the chest position of the pigs can be positioned between the ruler adjustment measuring module 7 and the misaligned ruler moving module 8. When the pigs' heads are inserted into the groove to eat, the second rotating device 713 is activated to drive the upper measuring ruler adjustment mechanism 704 to rotate. The measuring ruler adjustment mechanism 704 and the inner wire winding mechanism 712 are activated simultaneously. This allows the measuring ruler adjustment mechanism 704 to be precisely positioned on the surface of the measuring ruler 705. The measuring ruler 705 is slowly pushed to contact one side of the pig's torso with the skin above the body. Then, the other two sets of wire winding mechanisms 713 release the measuring ruler 705. The misaligned ruler moving module 8 is then activated to tighten the measuring ruler. At the same time, the misaligned ruler moving module 8 will drive the measuring ruler 705 at one end to dock with the measuring ruler 705 at the front end to close, making it convenient to observe the chest circumference data. The third rotating device 801 drives the arc-shaped misalignment plate 802 to rotate, causing the inner measuring ruler 705 to move towards the ruler body adjustment measuring module 7. During the movement, the automatic winding device 803 can be activated simultaneously to wind up the measuring ruler 705, ensuring that the measuring ruler 705 surrounding the outer side of the experimental pig's chest is accurate. The pressure detection unit in the temperature and pressure integrated detection unit 714 can use a semiconductor strain gauge, which is small in size and can detect minute pressures. Once the pressure reaches the set threshold and the temperature sensor detects the temperature of the experimental pig, it indicates that the measuring ruler 705 is in contact with the outer skin of the experimental pig's chest, thus avoiding excessive tightening of the automatic winding device 803 and excessive pressure on the experimental pig, which could cause stress. The integrated measurement module 4 can automatically detect other physiological parameters of the experimental pigs.

[0029] Example 2: This example is an improvement on Example 1. Please refer to Example 1. Figure 3 and Figure 4 Specifically, a lifting mechanism 709 is fixedly connected inside the housing 701. A rotating plate 710 is rotatably connected to the top of the lifting mechanism 709. The other end of the rotating plate 710 is rotatably connected to the inclined connecting plate 706.

[0030] The connecting plate 706 has a guide post 711 that is slidably connected inside, and one end of the guide post 711 is fixedly connected to the housing 701.

[0031] A blower 707 for heating air is also installed on one side of the connecting plate 706. A vertically arranged preheating pipe 708 is installed on the top of the blower 707, and a uniformly distributed exhaust hole is opened on one side of the preheating pipe 708.

[0032] The outer side of the measuring ruler 705 is engraved with evenly distributed graduations, and a limit baffle 715 is provided at the zero graduation position on the surface of the measuring ruler 705.

[0033] Before measurement, the blower 707 is turned on to heat the air. The hot air is discharged through the exhaust hole on the side wall of the preheating tube 708 to preheat the measuring ruler 705, which will be in contact with the skin of the experimental pig's abdomen. This reduces the temperature difference between the ruler and the skin, thereby reducing the probability of stress response in the experimental pig. The aforementioned temperature and pressure integrated detection unit 714 can provide real-time feedback of pressure data to ensure that the measuring ruler 705 is in close contact with the pig's skin without excessive pressure. This ensures the accuracy of the measurement data while avoiding causing physiological discomfort to the experimental pig. Also includes the following: Medium-sized experimental pigs are significantly more sensitive to unfamiliar environments and close human intervention than small experimental pigs. When people stand around the enclosure, the pigs tend to perceive them as potential threats, exhibiting pre-stress behaviors such as raising their heads alertly, tensing their limbs, and pacing slightly. If people frequently move around, bend over, or reach out, it will further exacerbate the pigs' anxiety and may even induce violent stress responses such as struggling and agitation. These stress responses caused by human intervention have a cumulative effect with the physical stimulation stress response generated by the ruler contacting the skin during chest circumference measurement. This not only significantly increases the difficulty of on-site measurement but also causes measurement data deviation due to abnormal body movements of the experimental pigs, seriously affecting the accuracy of the data.

[0034] This device adopts an automated measurement mode, which can effectively isolate personnel from experimental pigs. Operators do not need to have close contact with experimental pigs. They only need to stand at the end of the device to complete the observation and data reading of the measurement process, thereby reducing the probability of stress to experimental pigs caused by human factors from the root. In actual measurement operations, the lifting mechanism 709 is activated to drive the rotating plate 710 above it to deflect at an angle. The rotating plate 710 simultaneously pushes the connecting plate 706 to move along a preset direction, thereby causing the upper unit moving plate 702 and the lower unit moving plate 703 to move inward toward the guardrail 2. Finally, the measuring scale adjustment mechanism 704 is accurately positioned directly above the experimental pig's torso, providing a positional reference for the accurate conduct of subsequent measurement operations. At the same time, the guide column 711 configured in the device can limit and guide the movement trajectory of the connecting plate 706, ensuring the stability and smoothness of its movement process.

[0035] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 5 Specifically, the measuring scale adjustment mechanism 704 includes a rotating frame 7041 fixedly connected to the second rotating device 713. The other end of the rotating frame 7041 is fixedly connected to the measuring scale 705. A wire take-up mechanism 712 and a first rotating device 7042 are installed on the inner side of the rotating frame 7041. An adaptive arc-shaped telescopic member 7043 is fixedly connected to the movable end of the first rotating device 7042. A protective cover 7044 is fixedly connected to the other end of the adaptive arc-shaped telescopic member 7043. A rotating wheel 7045 is rotatably connected to the inner side of the protective cover 7044.

[0036] During the measurement ruler's rotation, the first rotating device 7042 drives the adaptive arc-shaped telescopic component 7043 to rotate, causing the protective cover 7044 at its end and the rotating wheel 7045 to move synchronously. The rotating wheel 7045 abuts against one end of the measuring ruler 705 and slowly moves along the ruler's extension direction to the limiting baffle 715, where it docks with the measuring ruler 705 on the side of the misaligned ruler moving module 8 to form a closed measurement loop around the pig's body, facilitating the reading of accurate data. The limiting baffle 715 has a limiting sensor inside to prevent the rotating wheel 7045 from rotating excessively. In actual operation, if the rotating wheel 7045 rotates and separates from the measuring ruler 705, it can be manually reset.

[0037] The measuring ruler adjustment mechanism 704 and the misaligned ruler moving module 8 adopt a misaligned layout design, which can effectively avoid collision and interference between the two during movement. Compared with the vertical plane deviation problem that is easy to occur when manually wrapping the measuring ruler, the misaligned drive structure of this device can ensure the verticality of the measuring plane and further improve the measurement accuracy of chest and waist circumference data. Also includes the following: The adaptive arc-shaped telescopic component 7043 has an automatic telescopic function. When the rotating wheel 705 on one side presses the measuring ruler 705 and contacts the top of the experimental pig's torso, it can automatically adjust its length to make it stably positioned at the limit baffle 715, which facilitates docking and reading of the measuring ruler 705.
