Patent ID: 10098571

Abstract:
Disclosed is a digestive tract patency capsule, comprising an outer membrane (2) and a supporting material (1) which is soluble in digestive juices. The outer membrane (2) is a sealed soft capsule body made from a sustained-release enteric material, and the dissolution time of the outer membrane (2) is greater than the normal emptying time of the human digestive tract. The cavity of the capsule body of the outer membrane (2) is provided with an indicator (5) which can be absorbed by the body and enables the discharged urine to change color. The supporting material (1) is provided in the cavity of the capsule body of the outer membrane (2) to support the outer membrane (2) in a capsule form. The digestive tract patency capsule can safely and effectively check the feasibility of performing a capsule endoscopic examination on a user. The digestive tract patency capsule can predict the feasibility of a capsule endoscopic examination and is taken before performing a capsule endoscopic examination on a patient, thus safely, simply and effectively providing a good basis for the determination of whether a capsule endoscopic examination should be performed for a clinician.
