The single-use fine-tube powder direct-insertion drug delivery device consists of a medical-grade PP tube body, rubber piston, push rod, and protective cap. Sterile and individually packaged, it is easy to operate and suitable for self-administration at home. Compared with traditional dosage forms such as washes, sprays, and suppositories, this device enables the drug powder to adhere tightly to mucosal surfaces within narrow body cavities, providing prolonged efficacy without solvent irritation, ensuring precise dosing and eliminating the risk of cross-infection. The device can be used in multiple narrow human cavities: in gynecology, it treats vaginal inflammation and promotes wound healing after surgery; in proctology, it effectively manages conditions like hemorrhoids and anal fissures, enhancing drug bioavailability; and in nasal applications, it improves rhinitis and post-surgical wound recovery with minimal medication use and low side effects. Meeting both physician and patient needs, the product offers stable storage, low cost, and customizable dimensions, demonstrating broad application potential in non-invasive local drug delivery.
