[0002] Dynamic MRI examination of the pelvic floor is an imaging examination method used to evaluate the structure and function of the pelvic floor. It uses magnetic resonance imaging (MRI) technology to image the pelvic floor in a resting state and when simulating pelvic floor functional movements. It can clearly show the morphology and position changes of the pelvic floor muscles, fascia, organs and other structures, and plays an important role in diagnosing pelvic floor dysfunction diseases.

[0003] In the pelvic floor MRI examination technology with interventional guidance function, in order to more accurately observe the vagina, rectal wall and the surrounding fine structures, by injecting sterile coupling agent into the cavity, which can better display the interface and reduce artifact interference, it helps to obtain clearer and more accurate images, which is convenient for accurately judging the tissue structure morphology and lesions.

[0004] When injecting the sterile coupling agent, a syringe is usually used to inject the sterile coupling agent into the patient's vagina and anus. However, due to the viscous texture of the sterile coupling agent, the resistance encountered when injecting the sterile coupling agent into the patient's vagina and anus through the syringe is too great, making it difficult to quickly inject the sterile coupling agent into the patient's body, resulting in low efficiency.
