| 摘要 |
The present invention is a suppository (10) for use in an anal canal that comprises a shaft (2) having a first end (7) and a second end (8). A ring (3) is attached between the first end (7) and the second end (8) of the shaft (2). The shaft (2) is generally cylindrical between the first end (7) and the second end (8). The shaft (2) has a length of between 3cm and 6cm inclusive, and the diameter of the shaft (2) is between 2 mm and 8 mm inclusive. The ring (3) has a optimum diameter of no more than 2 times the diameter of the shaft (2), and the maximum diameter of the ring (3) is 12 mm. The minimum length of the wide section (4) of the ring (3) to either end of the shaft is 2 centimeters. All of those numerical figures are approximate.
