Small, medium-sized animal experiment
Small, medium-sized animal experiment
With the rise of domestic scientific research, continuous improvement of the funding of the staff, but The working environment of the clinicians leads to researchers to raise large and medium-sized experimental animals such as rabbit, guinea pigs, dogs in their laboratory
Small, medium-sized animal experiments [123 At the time, in order not to damage the health of the animal, it does not affect the observation indicator, and prevent the animal's activity, first limit the animals, so that the animals are in a quiet state, the staff masters the reasonable grasp of the fixed method.

The palm, the ringless finger and small finger clamp its back skin and tail, you can fix mice. In some special experiments, such as a special fixture, such as a special fixture or a thick glass test tube using a special fixture or a coarse glass test. To carry out surgery or cardiac blood collection, anesthesia should be carried out first. If the anatomical experiment is done, it will be done.

Because of the big rabbit, the people often mistakenly think that they can mention their ears, or some people use hands to hold their waist backThe portions are incorrect.
In the experimental work, rabbits were used to blood, intravenous injection, so the two ears of rabbits should be kept not damaged. The fixed method of rabbits has cassette fixed and desktop fixation. The cassette fixation is suitable for blood collection and ear vascular injection, and the desktop fixation is suitable for measuring blood pressure, breathing, and surgical operation.
