Technical Field
The invention relates to the technical field of mice experiments, in particular to a device for measuring heart rate of mice.
Background
The mice commonly used for experiments mainly have the following reasons:
first: the gene sequence in mice is very similar to human, so that many diseases which are difficult to cure by human can find similar characters in mice, and the disease curing genes are found through experiments.
Second,: the biological significance of the special white mice for experiments is large, and the cultured mice have almost no individual difference (physiological significance). Whether there is no individual difference in physiology means that there is no difference in the air quality is not known, but the pure experimental white mice were selected mainly for reducing the individual differences of the congenital origin as much as possible.
Third,: the number is sufficient and many experiments require statistical analysis, which requires a certain number of rats and mice, especially mice, to meet this requirement under artificial propagation conditions. Also animal grade, mice anyhow are also mammals, except for small body sizes, which are not inferior to the evolutionary levels of other mammals. Small body size is a favorable condition for artificial breeding and feeding.
Fourth,: many experiments were best performed with animals such as orangutans that are more closely related to humans, but the use of orangutans is too expensive. Many experiments, such as cognitive, require animals to be killed at the end of the experiment to check for internal changes. Thus, a large number of experiments must not be performed with the more "valuable" gorilla.
Fifth,: since such large mammals are protected by the animal protection association. Then many experiments that are not "humane" are limited. Even if mice are used, the animals still have a resistance.
Sixth: some experiments were not performed on large, complex animals.
However, when the heart rate of the mice is detected, the mice are inconvenient to walk easily by the mice Bai Shu, the mice are mostly fixed by the existing detection means, the walking of the mice is limited, the mood of the mice is changed, and the heart rate variation of the mice is seriously affected.
