TRANSANAL FLOW-IN CATHETER AND METHOD FOR INTERMITTENTLY INDUCING DEFECATION ADJUSTED IN REFLECTION ACTION

摘要

To provide a device for intermittently inducing defecation by transanally introducing an injection liquid into a rectum or a colon of a patient.SOLUTION: A device comprises an air injection type balloon 2 having a waist-slender shape, in particular, a dumb-bell shape or a sandglass shape, and the balloon comprises terminal end balloon parts 4, 5 having larger radii, and an intermediate balloon part 3 arranged between the terminal end balloons and having a smaller radius. A remotely-adjoining and radially-expanded balloon part is arranged in a rectum, and a proximally-adjoining and radially-expanded balloon part is arranged outside a body, and end parts of both the balloons are tapered up to a shaft dimension of a catheter shaft 1 for supporting the balloons, and fixed on an outside-coated surface of the catheter shaft in an invaginated state. Filling pressure in the balloons is incremented by two stages or more until an intestinal wall part is expanded, and adjusted defecation reflection is induced. The timing and intensity of an induction stimulus may be decided up to a possible maximum value by a user.SELECTED DRAWING: Figure 1a
