Description

A mouse Housanli acupoint protection and fixation device

technical field

The utility model relates to the field of fixing devices, in particular to a protection and fixing device for Housanli acupoints of mice.

Background technique

The limb posture and mental state of small animals used in experiments are particularly important prerequisites for the results of animal experiments, especially the intervention effects related to physical therapy and the outcome indicators of behavioral experiments. In the past, acupuncture-moxibustion interventions involving acupoints in the mouse's hind limbs (such as "housanli"), whether it was electroacupuncture (EA) or moxibustion (mox ibust ion), required treatment of the mouse's hind limbs or even the whole body. The reasons for using mice for the experiment are as follows: 1. The gene sequence of mice has a high similarity with human beings, reaching more than 99%. Its whole genome is very similar to human beings, and many diseases that are difficult to cure can be found in mice, so that the therapeutic genes can be found through experiments; 2. The biological significance is great, and the experimental mice are the experimental environment Specially bred with little to no individual variation (physiologically). Whether there is no individual difference in physiology means that there is no difference in structure is not yet clear, but the main purpose of choosing pure-line experimental mice is to reduce the congenital individual differences as much as possible, so as to better explain the law and effect of medical intervention on organisms. effective mechanism. 3. Sufficient quantity. Many experiments require statistical analysis, which requires a certain number. Rats and mice, especially mice, have a high annual litter size under artificial breeding conditions, which can meet this requirement. 4. The size of the animal. The little white mouse belongs to the vertebrate phylum, mammals, rodents, and murines, and its build is relatively small, with an adult male body length of about 20cm (the length of the tail is about 10cm). The small size has become a favorable condition for artificial breeding and feeding. Because of the small size of mice, it is difficult to target acupuncture points for acupuncture intervention. Moreover, when the mice were awake, they struggled and feared, which made acupuncture more difficult. More importantly, it is impossible to maintain a stable natural state, such as blood pressure, heart rate, hormone levels in the body, etc., which will cause a series of interference factors to the experimental results. To sum up, the problems mentioned in the background art exist objectively and need to be improved urgently.

However, at present, most of the relevant devices in this field are focused on a single paradigm of Baoding the whole body of mice, which cannot meet the dual needs of "baoding + exposure (acupoint area)" in the experimental research of acupuncture and moxibustion. How to present the "housanli" acupoint in the hindlimb region with the appropriate joint angle and position under the premise of the whole body of awake mice in Baoding is one of the key problems that need to be solved urgently in the operation of acupuncture and moxibustion experimental research. Therefore, the core goal of the device we designed and built is to solve the problem of simultaneously satisfying the restraint and exposure (acupoint area) of awake mice. This device can provide acupuncture researchers with stable mouse body position and behavior restraint, and more importantly, it can reasonably expose the "housanli" acupoint area in a functional joint posture, so as to facilitate subsequent acupuncture and moxibustion operations. In combination with the above-mentioned problems in the use of the fixation device, a protective fixation device for the Housanli acupoint of mice is now proposed."
