Description

Technical Field

[0001] This utility model relates to the technical field of conducting acupuncture experiments on rats, and specifically to a rat restraint device that facilitates the conduct of acupuncture experiments. Background Technology

[0002] The rat acupuncture experiment aims to establish an animal model for acupuncture research, simulate human diseases, reveal the mechanism of action of acupuncture, the specificity of meridians and acupoints, evaluate the efficacy and safety, optimize the technique, and provide a basis for clinical application.

[0003] In acupuncture experiments on rats, rats need to be immobilized using a rat restraint device to facilitate acupuncture. Existing rat restraint devices generally employ a cylindrical structure. For example, patent announcement CN205459183U discloses a rat acupuncture restraint device that uses a mesh-like cylindrical body restraint tube. The rat is placed behind the body restraint tube, and hind limb restraint forks, forelimb restraint forks, and two neck restraint rods are inserted crosswise through the body restraint tube to immobilize the rat. Another example is patent announcement CN203988472U, which discloses a rat restraint device for acupuncture. This device has a body restraint device and a head restraint device mounted on a base. The rear end of the head restraint device is connected to the front end of the body restraint device. The rat is immobilized through an air bladder inside the body restraint device. The body restraint device has a mesh structure and is used for acupuncture. However, when using this cylindrical rat restraint to perform acupuncture experiments on rats, it is not convenient for the acupuncturist to touch the rat's body through the mesh-structured body restraint tube. It is difficult to locate some acupoints on the rat's body. Moreover, the mesh-structured body restraint tube can also obstruct some acupuncture points on the rat's body, affecting the acupuncture and making the operation inconvenient. Utility Model Content
