Description

Posture corrector for experimental animal

Technical Field

The utility model relates to a biological assay technical field especially relates to an experimental animals position unscrambler.

Background

With the progress of modern biomedical animal experiments and the improvement of the ethics of experimental animals, the introduction rate of living body detection instruments in experiments is gradually increased. During the use of the instrument, the animal is required to keep a certain position or move to a certain position or area (for example, when the load difference of the two hind limbs of a big mouse and a small mouse is measured, the two hind limbs of the laboratory mouse are required to be respectively placed on two separate pedals). And the experimental apparatus has the devices which are harmful to the human body because the internal space is narrow or the experimental apparatus is provided with the low-voltage lead wire which is used for stimulating the experimental animal, and the like, so that the experimental personnel can not operate manually. In contrast, in the experimental process, experimenters often drive experimental animals to a specific area or position by using a wooden stick and the like, and although the process has many defects, no effective equipment or technical method is provided for solving the problem.

When the angle of the clamping opening is proper and the clamping opening needs to be used for a long time, the fixing screw can be screwed, so that the angle of the clamping opening can be fixed.

Further, a lower insulating anti-slip cover 13 is further provided on the outer portions of the fixed handle 11 and the movable handle 12.

Further, a telescopic insulating sleeve 14 is arranged between the movable handle 12 and the extension part 20, so that the end part of the extension part 20 is connected with the movable handle 12 after penetrating through the telescopic insulating sleeve 14. The lower insulating anti-skidding sleeve 13 is arranged at the operation position of the near end, the telescopic insulating sleeve 14 is arranged outside the traction rope exposed at the near end, and therefore, when the device touches a low-voltage lead arranged for stimulating experimental animals in a test instrument, the device is prevented from being injured or uncomfortable by experimenters, the safety of the experimenters is guaranteed, and the operation is convenient.

Furthermore, a first guide wheel 22 is further arranged at one end of the extension portion 20, a second guide wheel 23 is arranged at the other end of the extension portion 20, the first guide wheel 22 is rotatably connected with the extension portion 20, the second guide wheel 23 is rotatably connected with the extension portion 20, a hinge point is formed by the fixed claw 31 and the movable claw 32, and the extension portion 20 is S-shaped to pass around the hinge point, the first guide wheel 22 and the second guide wheel 23.

Through the first guide wheel 22 and the second guide wheel 23, the drawing rope of the telescopic part can be drawn, the movable claw 32 is pulled to rotate for 150 degrees, the movable claw 32 is driven to rotate for 180 degrees, the movable claw 32 is driven to move to one side of the fixed claw 31 and is arranged opposite to the fixed claw 31, the movable claw 32 is bent towards the operation end of a person to form a hook shape, at the moment, the protection stop lever 34 can still protect the animal, the fur of the animal is prevented from being directly contacted with the hinged point of the hook-shaped movable claw 32, and the body part of the animal is pulled back through the hook-shaped movable claw 32, so that the fixed claw 31 and the movable claw 32 are in two states, and the first state is that the fixed claw 31 and the movable claw 32 are in an arc clamp shape and can clamp the tail of the animal by being pushed forwards; the other state is that the movable claw 32 is separately hooked and can pull back the body part of the animal, thereby achieving two purposes.

In the prior art, when an animal is pushed forwards or clamped, a wooden stick or a slender rod is adopted to push the animal forwards, however, because the experimental apparatus is sometimes a labyrinth test or a multi-surface closed experimental apparatus, only an opening of an operation opening is provided for a human to operate, the animal can be retracted towards a corner or extends into the corner, the animal is difficult to come out, the animal needs to be pulled back at this time, when the animal needs to be pulled back, the existing method is to replace a tool or has no tool at all, and the experiment can be continued only after the animal is calm. So integrate two kinds of functions as an organic whole in this scheme, need not the change instrument, can realize.

The embodiment of the utility model provides a module or unit in the device can merge, divide and delete according to actual need.
