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.

The intravenous injection auxiliary fixing device comprises a box body, the top face of the box body is open, a first groove penetrating through the box body is formed in the back face of the box body, a second groove penetrating through the box body is formed in the front face of the box body, and the second groove and the first groove are aligned front and back. And two clamping grooves are symmetrically formed in the lower surface of the second groove. According to the utility model, the tail part of the rat is straightened and is flatly placed on the two seat plates, the twisting handle is held, the screw rods move downwards, and the two screw rods respectively drive the pressing plates to move downwards, so that the bent parts in the middle of the pressing plates can press the tail part of the rat; the number of the pressing plates is two, the whole tail of the rat can be firmly pressed, and therefore an injector can be conveniently used for intravenous injection towards the tail of the rat. The first elastic band and the second elastic band can be fixed on the first convex column and the second convex column at different positions, so that the downward pressure of the first elastic band and the second elastic band on the neck and the hip of the rat can be adjusted.

A placing cylinder for injection comprises a cylinder body, the two ends of the cylinder body are open, an end cover is arranged at one end of the cylinder body, a movable rod is arranged on the end cover in a penetrating mode, a restraining disc is arranged at the inner side end of the movable rod and located in the cylinder body, and a plurality of ventilation holes are formed in the periphery of the cylinder body so that white mice in the cylinder body can breathe conveniently. The restraining disc can limit the activity space of the white mouse, so that the white mouse is prevented from being stimulated to move inwards, and meanwhile, the position of the restraining disc can be conveniently adjusted through the arrangement of a movable rod. According to the utility model, the activity space of the white mouse can be restrained, so that the injection operation is prevented from being influenced by the movement of the white mouse in the tail injection process, and meanwhile, the white mouse can be conveniently placed.

The invention relates to the technical field of glucose clamp tests, in particular to a glucose clamp test device based on a negative feedback model, which comprises a table body, a test box is fixedly mounted on the front side of the upper surface of the table body, box doors are rotatably mounted on two sides of the front end of the test box respectively, and a fixed clamping plate is connected to the inner side of the test box through an XY-axis moving mechanism; an upper connecting plate and a lower connecting plate are fixedly connected to the upper end and the lower end of the fixed clamping plate respectively, a movable clamping plate is connected to one side of the fixed clamping plate through an inserting mechanism, a sliding opening is formed in the upper surface of the upper connecting plate in a penetrating mode, and two sliding blocks are slidably inserted into the inner side of the sliding opening through elastic meshing mechanisms respectively; the device has the function of positioning the white mouse, the white mouse does not need to be subjected to anesthesia treatment or binding treatment in a test, and operation is convenient; a punctured needle head can be firmly positioned, so that the problems of separation and looseness are prevented; and the problem that the rear legs of the white mouse touch the connecting pipe can be effectively prevented, so that the test is blocked.
