Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of acupuncture fixation of experimental mice, in particular to an acupuncture fixer for experimental mice. Background Art
[0002] Acupuncture and electrotherapy for laboratory mice is an experimental method that is often used to study the effects of acupuncture and electrotherapy on the physiological and pathological responses of animal models, especially laboratory mice. This experimental method combines acupuncture and electrical stimulation to reveal the potential mechanisms of acupuncture and electrotherapy in treating diseases or relieving symptoms. In experiments on acupuncture and electrotherapy, researchers usually apply electrical stimulation to specific sites on laboratory mice to simulate the effects of acupuncture treatment. This stimulation can trigger nerve signals and may affect the function of internal organs corresponding to specific acupoints. In this way, researchers can observe the response of laboratory mice to treatment and further study the effects of acupuncture and electrotherapy on inflammation, pain or other disease states.
[0003] When in use, the above device does not have the structure of turning over the experimental mouse for acupuncture on the back and abdomen, fixing the experimental mouse's head and mouth, and quickly fixing experimental mice of different body sizes. As a result, in the prior art, when fixing the experimental mouse, most of the experimental mice are directly placed on the experimental table for acupuncture and electrotherapy. Since the experimental mice have acupuncture points on the back and abdomen, it is difficult for the experimental mice to turn over and perform acupuncture on the abdomen after the needles are inserted into the back. At the same time, since the body shapes of the experimental mice are different, if an integrated fixing frame is used, it cannot be adapted to experimental mice of different body sizes. In addition, due to the limitation of the shape of the experimental mouse's head, fixing the head is relatively cumbersome. Based on the deficiencies of the existing technology, the utility model designs an acupuncture fixer for experimental mice. Utility Model Content
