Decomposable patency capsule

Abstract

The invention discloses a decomposable patency capsule. The decomposable patency capsule comprises an inner core used for sending signals to the outside and a disintegration shell wrapping the inner core and used for simulating the shape of a capsule endoscope, wherein the disintegration shell comprises at least two disintegration units and a bonding part for bonding and connecting the disintegration units, and the bonding part is a degradable material piece and is completely degraded after entering the digestive tract for a target time, so that the bonded and connected disintegration units are separated. In the using process of the decomposable patency capsule, the disintegration shell disintegrates after entering the digestive tract for a period of time, the whole patency capsule is decomposed into the inner core and the disintegration units, the size of the inner core and the size of the disintegration units are both smaller than the size of an original patency capsule, a user can discharge the patency capsule conveniently, the patency capsule is prevented from staying in the body of the user; and besides, the size of each part of the decomposed patency capsule is greatly different from that of the original patency capsule, so that distinguishing is facilitated, and doctors can observe and judge conveniently.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, relates to a decomposable path-finding capsule. Background technique [0002] The examination methods currently used to evaluate the patency of the small intestine include CT imaging (CTE) of the small intestine, magnetic resonance imaging (MRE) of the small intestine, and the Pathfinder capsule; the Pathfinder capsule does not require complicated intestinal preparation and does not require radiation exposure. In addition, because the size of the Pathfinder capsule is close to that of the capsule endoscope, swallowing the Pathfinder capsule can simulate the swallowing process of the capsule endoscope for some patients, especially children, so that these patients can reduce the need for the capsule endoscope. The fear of swallowing reduces the swallowing time of the capsules. [0003] Regarding the detection of whether the Pathfinder Capsule stays in the body, it ca...

AI Technical Summary

Problems solved by technology

[0004] Existing Pathfinder capsule products will actually reduce the volume of the capsule at the end of the target working time, and the doctor will also judge that if the capsules excreted from the body do not undergo excessive volume changes, it will depend on the user’s digestive tract. There is a risk of retention; however, the quantifiable clinical effect of this situation is not good, and the doctor's experience should be used as the basis for judgment, so there may be a risk of misjudgment
