Objective: To study the clinical efficacy of applying the Meridian Flow Low-Frequency Therapy Device combined with Chinese herbal enema for patients with acute and chronic pelvic inflammatory disease (PID). Methods: Sixty-two patients with acute and chronic PID admitted from January 2024 to October 2025 were selected and randomly divided into a standard group (n = 31) and an experimental group (n = 31). The standard group received conventional medication + Chinese herbal enema treatment. The experimental group received the Meridian Flow Low-Frequency Therapy Device in addition to the standard group’s treatment. The clinical efficacy, changes in inflammatory markers, and pelvic improvement were compared between the two groups. Results: The excellent-good rate of treatment in the experimental group was higher than that in the standard group (p < 0.05). The levels of various inflammatory factors in the experimental group were lower than those in the standard group (all p < 0.05). The improvement in pelvic mass diameter and pelvic effusion depth in the experimental group was superior to that in the standard group (both p < 0.05). Conclusion: The Meridian Flow Low-Frequency Therapy Device combined with Chinese herbal enema has a definite curative effect in treating pelvic inflammatory disease. It can effectively alleviate clinical symptoms, reduce inflammatory response, and promote the improvement of the pelvic environment.
