Description

Little white mouse heart rate experiment measuring device

Technical Field

The utility model relates to a mice experiment technical field specifically is a mice rhythm of heart experiment measuring device.

Background

The white mouse is commonly used for experiments, and has the following reasons:

firstly, the method comprises the following steps: the gene sequence in the mouse is similar to that of human, the whole genome has very high similarity to human, and many diseases which are difficult to cure by human can find similar characters on the mouse, so that the experiment shows that the disease curing gene is found.

Secondly, the method comprises the following steps: the biological significance of the special experimental white mouse is larger, and the cultured mouse almost has no individual difference (physiologically). Whether there is no individual difference in physiology means that there is no difference in the quality of the breath is not clear, but the choice of pure line laboratory mice is primarily to minimize the inherent individual differences.

Thirdly, the method comprises the following steps: 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 breeding conditions. Also, on an animal scale, the mice, the gangster, are mammals, and, except for small bodies, are not inferior to the evolution levels of other mammals. The small size of the body becomes the favorable condition for artificial breeding and feeding.

Fourthly: in fact, many experiments are best performed with animals that are more similar to humans, such as orangutan, but the use of orangutan is too expensive. Many experiments, such as cognitive, require that the animals be sacrificed after the experiment is completed to examine their internal changes. Thus, a large number of experiments certainly do not allow the use of relatively "valuable" orangutans.

Fifth, the method comprises the following steps: since this large mammal is protected by the animal protection society. So many non-humane experiments are limited. Even though mice were used, the animals still had protest.

Sixth: some experiments were not performed with large, complex animals.

However, when the heart rate of the white mouse is detected, the white mouse is easy to walk and inconvenient to detect, most of the existing detection means fix the white mouse, the walking of the white mouse is limited, the mood of the white mouse can be changed, and the heart rate change of the white mouse is seriously influenced. Therefore, the experimental measurement device for the heart rate of the white mouse is provided.
