Endoscope pretest capsule |
摘要 |
An endoscope pretest capsule has approximately the same shape and weight as a capsule-type endoscope and is brought into the body before applying the capsule-type endoscope, and it includes barium sulfate which is a radiopaque substance (or a microcapsule wrapping a radiopaque substance) in a capsule body formed by a material having main components such as chitosan, and has an enteric coat for dissolving after elapse of a predetermined time provided on the surface side thereof. It is possible, by having the pretest capsule swallowed by an examinee in advance, to grasp passage conditions of the capsule-type endoscope in the body and secure good discharge out of the body because it dissolves in the case of remaining in the body for the predetermined time or longer. |
