Description

Technical Field

[0001] The utility model relates to the technical field of specimen collection, in particular to an animal experiment specimen collection device. Background Art

[0002] Animal specimens are made by physical or chemical means to process the whole or part of an animal. Animal specimens play an important role in teaching and scientific research. The main types include immersed specimens, skinned specimens, skeletal specimens, dried specimens, slide specimens, etc. The identification of animal specimens is based on populations rather than individuals. Therefore, we should not rely solely on individual specimens, but on a series of specimens to select the model specimen. Species is the most basic element of the classification system. It is objective and has its own stable and clear boundaries. It can be distinguished from other species. Moreover, it is a breeding group.

[0003] When using traditional collection devices, it is difficult to adjust and fix large animals, resulting in the inability to fix the animal according to its body size for sampling. When in use, it is difficult to support the body of a large animal, resulting in the need for two or more workers to cooperate with each other to complete the sampling work. Based on this, the utility model designs an animal experiment specimen collection device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an animal experiment specimen collection device to solve the problems raised in the above background technology.

[0014] 1. The utility model can fix the limbs of large animals through a fixing mechanism, and the fixing mechanism includes a second servo motor, a bidirectional threaded rod, and a movable rod. When it is necessary to take samples from large animals, the staff adjusts the position of the movable rod according to the body size of the animal and starts the second servo motor. The second servo motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the movable rod to move during the rotation. When the movable rod is moved to a suitable position (at this time, the legs of the animal can be fixed according to a number of limit ropes), the second servo motor is stopped. At this time, the legs of the animal can be fixed, which is convenient for the staff to take samples from it.

[0027] An animal experiment specimen collection device comprises an operating table 1, a fixing mechanism and a supporting mechanism, wherein the fixing mechanism comprises a first iron plate 403, the first iron plate 403 is mounted on the bottom of the operating table 1, a second iron plate 404 is also mounted on the bottom of the operating table 1, a second servo motor 405 is mounted on the outside of the first iron plate 403, a second bearing 409 is mounted on the outside of the second iron plate 404, a bidirectional threaded rod 406 is mounted on the end of the rotating shaft of the second servo motor 405, movable rods 407 are symmetrically arranged on the outside of the bidirectional threaded rod 406, and the free end of the bidirectional threaded rod 406 is connected to the second bearing 409; the legs of large animals can be fixed by using the bidirectional threaded rod 406 and the movable rod 407 in combination.

[0028] The supporting mechanism includes a first servo motor 301, which is disposed on the top of the operating platform 1, a one-way threaded rod 302 is installed at the end of the rotating shaft of the first servo motor 301, a first bearing 311 is disposed outside the one-way threaded rod 302, and a top plate 305 is installed outside the first bearing 311. The first servo motor 301 and the one-way threaded rod 302 cooperate to support large animals;

[0029] The operating table 1 has a strip groove 401 formed inside, a strip plate 402 is provided inside the strip groove 401, and the movable rods 407 are provided with strip through grooves 408. The movable rods 407 can be limited by the coordinated use of the strip plate 402 and the strip through grooves 408. A circular cover plate 304 is installed on the top of the one-way threaded rod 302, a limiting rod 303 is symmetrically installed outside the first servo motor 301, and a second through groove 308 is symmetrically provided outside the top plate 305;

[0030] The top plate 305 has a first through slot 306 symmetrically formed on the outside, and a limiting cloth strip 307 is provided inside the first through slot 306. The abdomen of a large animal can be fitted to the top plate 305 by using the first through slot 306 and the limiting cloth strip 307 in combination. A fixing rod 309 is provided at the bottom of the top plate 305, and a protective cover 310 is installed at the bottom of the fixing rod 309. The mouth of the animal is fixed by the protective cover 310. Several support columns 2 are symmetrically installed at the bottom of the operating platform 1. The third through slot 410 is symmetrically formed on the outside of the movable rod 407, and a limiting rope 411 is provided inside the third through slot 410. The legs of the large animal are fixed by using the third through slot 410 and the limiting rope 411 in combination.

[0031] When it is necessary to take samples from large animals (such as dogs, the bone marrow of large animals can be collected by live puncture. First, anesthetize the animal, fix it, remove the hair locally, and disinfect the skin. Then estimate the distance from the skin to the bone marrow and fix the length of the bone marrow puncture needle. The operator tightens the skin around the puncture point with his left hand, and inserts the puncture needle vertically into the puncture point with his right hand. After it is inserted and fixed, gently rotate the puncture needle left and right to drill it in. When the puncture needle enters the bone marrow cavity, there is often a sense of emptiness. The collection of dog bone marrow generally uses iliac puncture.

[0032] Common bone marrow puncture points for dogs and other large animals: Sternum: The puncture site is the connection between the body of the sternum and the manubrium of the sternum. Ribs: The puncture site is the midpoint of each point of the 5th to 7th ribs. Tibia: The puncture site is the concave surface on the inner side of the femur, near the lower end. If the puncture is performed on the ribs, the puncture hole should be sealed with tape after the puncture to prevent pneumothorax). Place the animal on the operating table 1. At this time, the movable rod 407 needs to be moved according to the size of the animal. Start the second servo motor 405. The second servo motor 405 drives the bidirectional threaded rod 406 to rotate. The bidirectional threaded rod 406 drives the two movable rods 407 to move during the rotation. Move the two movable rods 407 to the appropriate position. At this time, the third through-groove 410 and the limiting rope 411 can be used in combination to fix the animal's limbs for subsequent sample collection.

[0033] After fixing the animal's limbs, the animal's body needs to be propped up to collect ascites samples (for ascites in large animals such as dogs, let the dog be fixed in a natural standing position, and the puncture site is between the front edge of the pubic bone and the navel, on both sides of the midline of the abdomen. Hair clipping and disinfection, local infiltration anesthesia. The operator's left thumb and index finger tighten the skin at the puncture site, and the right hand controls the puncture depth for vertical puncture. Be careful not to puncture too deep to avoid puncturing the internal organs. After the puncture needle enters the abdominal cavity, when there is a lot of ascites, it can be seen that it automatically flows out due to high abdominal pressure. If there is too little ascites, it can be gently withdrawn and the needle can be slightly rotated at the same time. Once ascites flows out, fix it immediately The first through slot 306 and the limiting cloth strip 307 are used to fix the abdomen of the animal. After the abdomen of the animal is fixed, the first servo motor 301 is started, and the first servo motor 301 drives the one-way threaded rod 302 to rotate. The one-way threaded rod 302 drives the top plate 305 to rise and fall during the rotation. The top plate 305 supports the animal through the limiting cloth strip 307 during the lifting process, and the mouth of the animal is fixed through the protective cover 310, which is convenient for subsequent sample collection.
