Small animal fixation rack used for biology laboratory and fixation method adopted by small animal fixation rack

Abstract

The invention discloses a small animal fixation rack used for a biology laboratory and a fixation method adopted by the small animal fixation rack, belonging to the field of auxiliary instruments for the bioexperiments. The fixation rack comprises a fixation board, wherein a plurality of regulation holes are uniformly formed in the middle of the surface of the fixation board, and latch-type tying belts or nylon Velcro fasteners are placed in the regulation holes in a penetrating manner; and support legs are arranged at four corners of the bottom surface of the fixation board. The fixation method comprises the following steps: step 1, placing an anaesthetized small laboratory animal on the fixation board with the plurality of regulation holes, and spreading out the four limbs of the small animal; step 2, binding for fixing the four limbs of the small animal by adopting the latch-type tying belts or nylon Velcro fasteners; step 3, dissecting the small animal, tearing the epidermis apart left and right, and fixing the epidermis through the matched stretching of spring clips and rubber bands; and step 4, adjusting the position of an illuminating lamp, irradiating the internal organs, and observing and recording the experimental data. The fixation mode is flexible and is suitable for most in vivo experiments, the experiment efficiency is enhanced, and resources are saved.

Description

technical field [0001] The invention relates to a biological experiment auxiliary device, in particular to a small animal safety frame used in a biological laboratory and a fixing method thereof. Background technique [0002] Vivisection refers to the dissection of living animals for scientific research in physiology or pathology. Vivisection is performed under the conditions of anesthesia or destruction of the brain or spinal cord of the animal. Expose the organs and tissues to be studied for experiments. For example, to study the effect of the vagus nerve on the animal's heart rate and blood pressure, the vagus nerve that innervates the heart can be exposed by vivisection, and the common carotid artery cannulated and connected to the detection system for measurement. Therefore, the vivisection technique plays an important role in the success or failure of physiological experiments. very important role. [0003] In the traditional way, taking the mouse as an example, when...

Problems solved by technology

This patent has the following disadvantages: 1. The groove needs to be produced according to different experimental animal molds, which greatly increases the production cost; 2. For the same animal groove, due to the difference in body shape between animals, it is not suitable for smaller animals. For animals, it is impossible to achieve a fixed effect
