Abstract

An animal restraining apparatus and animal restraining procedure for using the same are provided. The experiment begins by preparing a live experiment animal, such as a mouse or rat coupled to a femoral vein/artery catheter via surgery. The experiment animal in a conscious state is then placed in a restraining apparatus. The restraining apparatus comprises a plurality of partitioning boards to partition the restraining space, such that the animal is restrained in the restraining space to prevent interference and infection from other animal, a supporting structure to carry the experiment animal, a rack for food and water, a signal receiver base, and a tail-fixing component fitted below or above the supporting structure. On the supporting structure, an opening is formed near the fixing component, with a guiding component formed outside the opening, such that the tail of the experiment animal can pass through the opening and follow the curvature of the guiding component until being restrained on the tail-fixing component. The curvature of the guiding component provides the least harmful and most natural curve for the tail of the rat or experiment animal. And by restraining the tail, the animal can be kept calm without agitation, while the animal is free to access food and water according to its physiological needs. Also, movement of the animal is kept to a minimum to prevent accidental catheter slippage.

Claims

1. An animal restraining apparatus applicable to physiological, pharmacological, and hemodynamic research, the animal restraining apparatus comprising:

a plurality of partitioning boards to partition a restraining space for placing at least one experiment animal;

a supporting board for carrying the experiment animal and the partitioning boards;

a fixing component formed outside the restraining space, wherein an opening is formed near the fixing component in the partitioning board and a guiding component having a pre-defined curvature is formed outside the opening, so that the tail of the experiment animal extends out from the opening and conforms to the curvature of the guiding component to occupy the same space with the fixing component; and

a binding component for fixing the tail of the animal on the fixing component, so that the lower body of the experiment animal is immobilized by fixing the tail.

2. The animal restraining apparatus of claim 1, wherein the fixing component is formed below the supporting board and the guiding component is formed on the supporting board.

3. The animal restraining apparatus of claim 1, wherein the guiding component is a metal ring and the metal ring has a curvature that conforms to in the natural tail curvature of the experiment animal.

4. The animal restraining apparatus of claim 1, further comprising a hole formed in the supporting board outside the opening for the tail to pass through.

5. The animal restraining apparatus of claim 1, wherein the experiment animal is a live experiment animal in a conscious state.

6. The animal restraining apparatus of claim 1, wherein the fixing component is formed below the supporting board.

7. The animal restraining apparatus of claim 1, wherein the fixing component is formed above the opening.

8. The animal restraining apparatus of claim 1, wherein the fixing component is formed behind the opening.

9. The animal restraining apparatus of claim 8, wherein the fixing component has an extended length to the length of the experiment animal'"'"'s tail.

10. The animal restraining apparatus of claim 1, wherein the binding component is an adhesive tape.

11. The animal restraining apparatus of claim 1, wherein the fixing component and the guiding component are mounted directly on the partitioning board, such that the tail of the experiment animal is hung up in a physiological position.
