On the basis of the above embodiment, the sealing shell 2 can be a shell with uniform thickness, so that the decomposition speed of each part is relatively uniform in the process that the sealing shell 2 enters the alimentary canal and starts to decompose, and the situation that partial sealing shell 2 is decomposed completely and is less can not occur.
The sealing shell 2 can be set to be a medical gelatin material piece or a palm wax material piece, and of course, the sealing shell can also be a mixed material piece meeting the requirements, the material pieces can be degraded in the digestive tract environment, and are nontoxic, harmless and free of side effects on a human body, and products after degradation can be absorbed by or discharged out of the human body, so that the harm to the human body is avoided.

In order to fix the degradation powder to the inner core portion 1, the density of the filled degradation powder may be increased appropriately, and considering that the larger the filling density is, the longer the degradation time of the degradation powder is, therefore, the specific filling density of the degradation powder needs to be determined according to actual conditions.
The degradation powder is uniformly distributed in the space enclosed by the sealing shell 2 and the inner core part 1, so that the inner core part 1 can be better fixed in the sealing shell 2, and when the degradation powder begins to degrade, the degradation speed of the degradation powder positioned at each part can be kept relatively consistent, and the degradation time of the degradation powder is optimized.
