The invention discloses a cylinder device for detecting anterior limb asymmetry of murine animals and a detection method. The cylinder device is composed of a double-layer transparent cylinder, a top wide-angle infrared camera, a detachable transparent touch-sensitive lining, a base rapid lock catch and a data processing unit. The lining coaxially overlaps the capacitor partition array and the ultrathin force-sensitive film, and outputs a touch position and a load-bearing signal in real time; the top camera synchronously collects videos, and forelimb sides and light / load-bearing touch are judged through timestamp fusion. The inertial measurement unit is arranged in the system to eliminate false signals, consumable sterilization replacement is supported, and after the set touch times or the statistical time is reached, automatic ending is achieved, and a report is generated. Compared with previous experimental equipment, the experimental device can intelligently obtain behavioral data of rats, judge forelimb side and light / load-bearing touch and eliminate false signals, and the behavioral data detection accuracy is high.

The invention belongs to the technical field of biology, and particularly relates to a scoliosis rat model construction method which comprises the following steps: S1, obtaining an experimental animal, removing the forelimb and the tail of the experimental animal, enabling the gravity direction of the experimental animal to be parallel to the spine, and obtaining a biped animal; s2, performing excision treatment on a deep paravertebral muscle group on one side of the biped animal to obtain an experimental animal with muscle mechanics imbalance; and S3, performing exercise load stimulation treatment on the experimental animal with muscle mechanics imbalance to obtain the scoliosis animal model. According to the method disclosed by the invention, the scoliosis animal model capable of highly simulating human disease characteristics is constructed by combining axial gravity load under a two-foot standing posture, structural and mechanical unbalance caused by directional unilateral deep paravertebral muscle excision and regular movement stimulation; the method can accurately and controllably induce scoliosis in a specific direction opposite to a muscle resection side, and has a wide application prospect.

[Solution] The information processing device (1) comprises an acquisition unit (101) that acquires an image of the end of a fetus's limb at the beginning of labor, an estimation unit (102) that inputs the image acquired by the acquisition unit (101) into a learning model that has been trained using learning limb images that are images showing the forelimbs and hindlimbs of at least one individual fetus after the beginning of labor and a newborn calf within five days after labor, and estimates whether the imaged end of the limb is a forelimb or a hindlimb, and an output unit (103) that outputs the estimation result by the estimation unit (102).

The utility model discloses a device for inducing intervertebral disc degeneration by standing both feet of a rat, which belongs to the technical field of animal models with human diseases and comprises a movable ring and a magic tape, a plurality of support legs are welded around the center of the bottom of the movable ring, universal wheels are arranged at the bottoms of the support legs, a fixed block is welded inside one end of the movable ring, and a fixing block is welded inside the other end of the movable ring. Connecting assemblies are arranged at the tops of the fixing blocks, binding assemblies are arranged on one sides of the connecting assemblies, and the hook-and-loop fasteners are located between the binding assemblies. The movable ring, the connecting assembly and the binding assembly are arranged, rats of different body types are fixed through cooperation of the back fixing plate and the chest fixing plate, spine bending of the rats is prevented, and after the binding assembly is connected with the movable ring through the connecting assembly, the rats can be forced to walk vertically so as to support modeling; the forelimb of the rat can extend out of the forelimb limiting groove, the forelimb is fixed through the forelimb limiting groove to prevent the rat from escaping, so that the forelimb of the rat does not need to be cut off through an operation, and the modeling process is simple and humanized.

This invention discloses an auxiliary device for artificial semen collection from sheep, including a base plate, a first pad and a second pad on the top of the base plate, a first positioning mechanism on the second pad that can clamp and restrain the sheep's forelegs, and a second positioning mechanism above the first pad that is driven by the first positioning mechanism to clamp and restrain the sheep's rump. This invention, through the pads and positioning mechanisms on the base plate, can assist in the artificial positioning and fixing of the forelimbs and buttocks of the estrus-induced ewe, so as to facilitate subsequent semen collection from the ram, making the process stable and efficient.

This application relates to a capture and disposal device for crown-of-thorns starfish, comprising a body structure, a nighttime identification device, a chemical injection device, a suction and crushing device, and a battery. The body structure includes a torso, a head, two forelimbs, and two hindlimbs connected by joints; an equipment compartment and a watertight cover are located on the back of the torso; the chemical injection device includes a storage tank, a metering chamber, a needle, a liquid guide tube, and a drive unit, with the storage tank, metering chamber, and drive unit located within the equipment compartment; the metering chamber has an inlet check valve and an outlet check valve at its end, the inlet check valve being connected to the storage tank via the liquid guide tube, and the outlet check valve being connected to the needle via the liquid guide tube; the suction and crushing device includes a processing chamber and a crushing impeller, with the crushing impeller disposed within the processing chamber. This application uses the chemical injection device to inject targeted chemical agents into the crown-of-thorns starfish; the suction and crushing device crushes the crown-of-thorns starfish and discharges it from its tail.

The invention belongs to the technical field of experimental animal operation auxiliary equipment, and discloses a rat jugular vein blood taking fixing table convenient for one-man operation, which comprises a blood taking base table and a rat fixing frame, the top face of the front portion of the blood sampling base is in a slope shape with the front portion lower than the rear portion, the top of the slope is vertically and rotatably connected with a head supporting plate, and a head fixing groove is formed in the head supporting plate. The rat fixing frame is detachably connected to the upper portion of the blood sampling abutment and comprises a U-shaped posterior limb fixing frame, a C-shaped forelimb fixing frame and a trunk fixing frame, the two ends of a C-shaped opening of the forelimb fixing frame are rotationally connected with the U-shaped opening end of the posterior limb fixing frame respectively, and four-limb fixing units with air bags are arranged on the posterior limb fixing frame and the forelimb fixing frame respectively. According to the fixing table, after a rat is fixed to the rat fixing frame, the whole fixing table is overturned and clamped to the blood taking base table, supine position fixing of the rat is completed, and single-person operation is achieved; the forelimb fixing frame and the posterior limb fixing frame can rotate up and down, so that the hypsokinesis angle of the neck of the rat can be conveniently adjusted, and the blood taking part is fully exposed.
