4 results about "White mouse" patented technology

The utility model discloses a folding cage for toxicology experiment, concretely relates to cage field, including bottom plate, one side of bottom plate is rotatively connected with first side plate, one side of first side plate is slidably connected with top plate, one side of top plate is rotatively connected with second side plate, and bottom plate is slidably connected at one side of second side plate, take mouse subassembly, and take mouse subassembly is connected with top plate and bottom plate respectively. The utility model discloses through setting bottom plate and top plate, by holding the top of top plate and the bottom of bottom plate with hand to the cage body, the top plate and the bottom plate are made to approach each other, and the first side plate and the second side plate are turned over and folded, so as to be convenient for storage and storage, and the elastic side plate and the push frame can compress the movable space of the white mouse, so as to be convenient for taking out the white mouse.

The utility model relates to the technical field of animal tests in low-pressure environments, in particular to an air pressure chamber for simulating animal tests in low-pressure environments, which comprises an air pressure chamber, belt pulleys are rotatably connected to two ends of the inner wall of the air pressure chamber, and a conveying belt is in transmission connection to the surfaces of the two belt pulleys. A transparent plate is hinged to the top end of the air pressure cabin through a hinge; the blocking mechanism is arranged in the air pressure cabin; the blocking mechanism comprises two check rings fixedly connected to the inner wall of the air pressure cabin, one side of each check ring makes contact with one side of the conveying belt, and the two ends of the inner wall of the air pressure cabin are slidably connected with check blocks. According to the device, through the check ring and the check block, the moving space of the white mouse on the inner wall of the gas-liquid cabin is limited, compared with the existing mode that the white mouse can move away from the conveying belt and enter the pipeline cavity, the white mouse in the scheme is not separated from the surface of the conveying belt all the time in the moving process, and the white mouse in the air pressure cabin is more convenient to take.

The experimental mouse head observation adapter comprises a base, one side of the top of the base is rotationally connected with a protection plate, the inner wall of the protection plate is slidably connected with a baffle, the inner wall of the baffle is in threaded connection with a first threaded rod, and the surface of the first threaded rod is rotationally connected to the surface of the protection plate; one end of the first threaded rod is fixedly connected with a first hand wheel, one side of the first hand wheel is rotatably connected to one side of the baffle, the other end of the threaded rod is fixedly connected with a gasket, and the surface of the gasket is rotatably connected to the inner wall of the protection plate. The situation that the position of the head deviates due to the fact that the white mouse is stimulated to twist the neck when the head of the white mouse is observed is avoided, large struggling of the white mouse can be effectively avoided by fixing the neck and the head of the white mouse at the same time, and due to the fact that the neck of the white mouse is fixed, the part, below the neck, of the white mouse can normally move.

The utility model discloses a positioning device for tail puncture of laboratory mice, which comprises a needle cylinder, and a push rod is arranged in the needle cylinder. The bottom side of the needle cylinder is fixedly connected to the connector; a needle head is detachably connected in the connector; the outer side of the connector is sleeved with a positioning device, and the positioning device comprises a positioning cylinder, an adjusting cylinder and a spreader; the positioning cylinder is fixedly sleeved on the outer side of the connector, and scales are arranged on the outer wall of the positioning cylinder; a gap is reserved between the inner wall of the adjusting cylinder and the outer wall of the needle head, and the bottom end face of the adjusting cylinder is flush with the bottom end face of the needle point. The bottom side of the adjusting cylinder is sleeved with the spreader. Through the cooperation of the positioning cylinder and the adjusting cylinder, the exposed length of the needle head each time can be adjusted, so that when experimenters respectively puncture the tails of a plurality of white rats, the inserted lengths of the needle head are kept consistent; in combination with the use of the dilator, the epidermal tissue wound punctured by the tail of the white mouse can be slightly expanded outwards, so that the irradiation of more light rays is facilitated, and the solidification of a tissue engineering scaffold material is accelerated.
