AI Technical Summary
When using existing rectal medication devices, the medication tends to leak out, making it difficult to accurately and fully contact the affected area, resulting in poor medication efficacy and affecting treatment outcomes.
An anorectal drug delivery device was designed, comprising a drug storage tube, a drug delivery tube, an air bladder, and a drive component. The drug delivery tube is fixed by the air bladder to ensure a tight seal, and the air bladder expands to fit tightly against the anorectal wall, reducing drug leakage. At the same time, the detachable connecting tube structure and sealing ring improve connection stability and sealing, and control the speed and amount of drug delivery.
This improves the contact between the medication and the affected area, reduces medication loss, ensures the medication works fully, and enhances the treatment effect.
