Owing to have employed technique scheme, the beneficial effects of the utility model are:
The rat oral gavage fixture that this utility model provides, comprises gripping device and arm protective sleeve, and gripping device is used for catching and fixing rat, and arm protective sleeve is not scratched by rat for the protection of the forearm of experimenter or bites, and it is reasonable in design.
During use; left hand or the right hand stretch in clip slot through arm protective sleeve; pull draw ring to make two intermediate plates open and catch rat, rat is fixed in grasping teeth, and the hands of experimenter is protected by arm protective sleeve by clip slot protection, arm; thus can not be bitten by rat or scratch; rat can be fixed by grasping teeth, and experimenter can carry out gavage operation, and it is simple to operate; save experimental period, can conventional efficient be improved.
Head fixing head is used for the head of fixing rat, the thumb of experimenter and forefinger stretch in two fingerstall respectively, thus make two fingers from the rear portion of head fixing head around to front portion, two fingers pinch the skin of rat neck thus the head of rat can not be swung, the head of rat falls within head layback groove and rat can be made pleasant, be conducive to experimenter and carry out gavage, can further improve conventional efficient.
Be connected by rotating shaft between fixed axis with arm protective sleeve, facilitate experimenter's wrist when arresting rat relatively more flexible, the hands of experimenter can be fixed in holding tank by fixing band, prevents gripping device slippage from experimenter's hands.
The circle cylinder that arm protective sleeve outer wall is provided with, for the afterbody of fixing rat, prevents rat tails whipping and affects gavage operation, thus affecting conventional efficient.
The end of grasping teeth is provided with rubber headgear and grasping teeth can be avoided to scratch or grab pain rat, makes rat more comfortable in gavage process.It is the bodily form having complied with rat that the length of multiple grasping teeth increases progressively successively, and the thin lower part of the body of upper body of usual rat is thick, is conducive to arresting and fixing rat.
The rat oral gavage fixture that this utility model provides, its structure is simple, reasonable in design, easy to operate, can catch rat quickly and fix rat preferably, experimenter can not be scratched or be bitten, be beneficial to experimenter and carry out gavage operation, shorten experimental period, improve conventional efficient.
