Abstract

The invention provides a tail loading device for swimming of a laboratory mouse. The tail loading device for the swimming of the laboratory mouse comprises an inner bushing and an outer bushing. The inner bushing is conical. The inner bushing is provided with a strip-shaped opening along the direction of the element of a cone, wherein the strip-shaped opening is communicated with two ports; a central angle which corresponds to the strip-shaped opening is smaller than 180 degrees; the inner bushing is provided with external threads; the inner surface of the outer bushing is in a truncated cone shape; and the inner surface of the outer bushing is provided with internal threads fitted with the external threads. The tail loading device for the swimming of the laboratory mouse provided by the invention is simple in structure and high in practicability, can be used for rapidly and effectively performing loading on the laboratory mouse, and moreover, the laboratory mouse cannot be hurt.

Description

technical field [0001] The invention relates to an experimental instrument, in particular to an experimental mouse swimming tail weight-bearing device. Background technique [0002] Fatigue model is an animal model used in many experimental projects in the field of life sciences, and the current common method for fatigue modeling is exercise fatigue modeling. In the manufacture of sports fatigue models, "swimming fatigue" has become the first choice in sports fatigue modeling because of its simple method, better modeling effect, more complete modeling evaluation system, and wide application. [0003] The experimental animals selected for the swimming fatigue model are mainly rats and mice. As we all know, both rats and mice have a strong swimming ability. In order to speed up the fatigue of the experimental subjects, we often add a certain amount of weight to the experimental subjects during the actual operation of the experiment, and summarize the common weight-bearing met...
