amounts of stool in every case it is possible to configure the plug 2 and or the sealing cap 10 such that an appropriately configured collection bag 23 can be fastened thereto as shown in fig5 the collection bag 23 has an annular flange 24 that can be connected to sealing cap 10 and a lid 25 that can be placed on inner sleeve 4 by the exertion of traction on lid 25 inner sleeve 4 is withdrawn from outer sleeve 3 and as represented in fig4 balloon 12 is withdrawn through the inner opening of outer sleeve 3 this procedure is illustrated in fig6 wherein outer sleeve 3 is also pulled out of opening 5 or its mounting in the cap 10 so that the stool can be emptied into the collection bag 23 fig7 shows the preformed balloon 12 with the connection ports 13 and 14 connection ports 13 and 14 have a relatively great length before they are used i e connected to plug 2 or sleeves 3 and 4 of plug 2 connection ports 13 and 14 are custom cut to an appropriate length depending on the thickness of the abdominal wall 6 the wall thickness of connection port 14 is preferably higher than the thickness of connection port 15 granting the formation of eyelets of sufficiently large diameter in the collapsed state of port 14 inside the body being inflated to seal pressure as shown in fig8 the balloon volume 28 also presses against a central lumen 26 and in so doing collapses inner hose segment connection port 14 as indicated by the thick line the central lumen 26 is thereby largely sealed keeping.
