A device for immobilizing the head and neck of softshell turtles

Abstract

The invention discloses a head and neck fixing device for a trionychidae animal. The head and neck fixing device comprises a clamp for clamping the mouth of the trionychidae animal, a first supporting rod and a second supporting rod, wherein the clamp comprises a first clamping body and a second clamping body; the middle of the first clamping body and the middle of the second clamping body are hinged; when the front end of the first clamping body gets into contact with the front end of the second clamping body, a gap is kept between the tail end of the first clamping body and the tail end of the second clamping body; one end of the first supporting rod is rotatably connected to the tail end of the first clamping body and one end of the second supporting rod is rotatably connected to the tail end of the second clamping body; half-clamping holes are formed in the other ends of the first supporting rod and the second supporting rod; and when the end of the first supporting rod is rotated to be close to the front part of the clamp and is connected to the end of the second supporting rod, the two half-clamping holes are spliced, so that a clamping hole for looping the neck of a soft-shelled turtle is formed. The device is simple to operate and is capable of stably fixing the head and the neck of the trionychidae animal, so that experimental operations on the trionychidae animal are greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of biological experiment equipment, in particular to a device for fixing the head and neck of softshell turtles. Background technique [0002] Soft-shelled turtles are important aquaculture animals in my country, mainly including Chinese soft-shelled turtles, Shanrui soft-shelled turtles and soft-shelled turtles. When performing experimental operations on softshell turtles, it is difficult to fix the neck because its neck can be retracted into the abdominal cavity, which brings great difficulties to the experimental operation. However, due to its ferocious nature, when an object approaches its mouth, the turtle will take the initiative to open its mouth and bite out of self-protection instinct. In the existing operating technology, the soft-shelled turtle is generally induced to bite a certain object first, and the neck is exposed during the stretching process. At present, there is no one that can stably cl...

When performing experimental operations on soft-shelled turtles, it is difficult to fix the neck because its neck can be retracted into the abdominal cavity, which brings great difficulties to the experimental operation

However, due to its ferocious nature, when an object approaches its mouth, the turtle will take the initiative to open its mouth and bite out of self-protection instinct.

In the existing operating technology, the soft-shelled turtle is generally induced to bite a certain object first, and the neck is exposed during the stretching process. At present, there is no one that can stably clamp and fix the soft-shelled soft-shelled animal's neck, which is convenient, safe and fast device for complete blood draw operation
