    In basic experimental acupuncture research, rats are commonly used as laboratory animals. However, it is difficult for them to maintain a fixed posture. During electroacupuncture procedures, proper immobilization of rats is essential. Various methods of rat fixation are currently used, including anesthesia fixation, high-platform fixation, binding fixation, and fixation with a self-made rat coat. However, these methods have their limitations, which may affect the efficiency and operability of the experiment to some extent. This protocol introduces a method of suspending and fixing rats using rat clothes. Firstly, rats are clothed with rat jackets that match their body shape, taking advantage of their preference for darkness and burrowing. The needling operation can then be carried out after the rats have worn rat clothes. When suspended, the rats are relatively still, as their limbs cannot move. This fixation method offers not only economical and user-friendly benefits but also ensures a stable and reliable fixation of the rats in a comfortably relaxed position. It also effectively minimizes time consumption, experimental space, and manpower resources. Additionally, this method allows for the exposure of most acupoints used for acupuncture in rats. This article primarily concentrates on the device's composition, encompassing a specially designed rat jacket, an elevated fixation rack, and their connecting structures. Additionally, an illustrative example will be presented to demonstrate the application of the rat clothing-based suspension fixation method in rat electroacupuncture procedures.
