AI Technical Summary
Existing long-acting enteric-coated capsules suffer from problems such as prolonged capsule dissolution time, uneven drug release, and slow drug efficacy.
A long-acting enteric-coated empty capsule is designed, which forms multiple drug release structures with different dissolution times by setting a first, second, third, and fourth containment cavities with different wall thicknesses and a central positioning partition, so that the drug is released sequentially.
This technology achieves long-term, uniform drug release and uniform drug efficacy, solving the problem of uneven drug release in existing technologies.

Abstract
Claims
1. A long-aging enteric- soluble hollow capsule characterized by: The capsule includes a capsule body (1), an upper partition plate (2), a first receiving cavity (3), a second receiving cavity (4), a middle positioning partition plate (5), an upper limit groove (6), a capsule cap (7), a lower partition plate (8), a third receiving cavity (9), a fourth receiving cavity (10), and a lower limit groove (11). The left and right sides of the capsule body (1) are separated by the upper partition plate (2) and the first receiving cavity (3) and the second receiving cavity (4) with different wall thicknesses are provided. The bottom of the capsule body (1) is fitted with a middle positioning partition plate (5). The top of the middle positioning partition plate (5) is provided with an upper limit groove (6) corresponding to the bottom end of the upper partition plate (2). The lower part of the capsule body (1) is fitted with a capsule cap (7). The left and right sides of the capsule cap (7) are separated by the lower partition plate (8) and the third receiving cavity (9) and the fourth receiving cavity (10) with different wall thicknesses are provided. The bottom of the middle positioning partition plate (5) is provided with a lower limit groove (11) corresponding to the top end of the lower partition plate (8).
2. The long-aging enteric- coated hollow capsule according to claim 1, wherein: The wall thicknesses of the first cavity (3), the second cavity (4), the third cavity (9), and the fourth cavity (10) are all different.
3. The long-aging enteric- coated hollow capsule according to claim 1, wherein: The centerlines of the upper partition plate (2) and the lower partition plate (8) are on the same straight line.
4. The long-aging enteric- coated hollow capsule according to claim 1, wherein: The central positioning partition (5) is positioned inside the capsule cap (7).
5. The long-aging enteric- coated hollow capsule according to claim 1, wherein: The top end of the lower partition plate (8) matches the lower limiting groove (11), and the bottom end of the upper partition plate (2) matches the upper limiting groove (6).
