An ostomy device comprising discharge device having a tubular member and an annular disc or a flange member, and the tubular member has a first end and a second end with a respective opening (25, 24) at each end (26, 23), the first end is insertable into the intestine of the person via the stoma such that the tubular member is positionable in the intestine of the person to discharge fluid and material from inside the intestine, from the opening at the first end of the tubular member to the opening at the second end of the tubular member, to the exterior of the body of the person, the intestine used to form the stoma, and the annular disc or the flange member is provided at the second end of the tubular member such that the tubular member extends from the annular disc or the flange member on a first side of the annular disc or the flange member, characterised by: an implant arranged, in use, to be located inside the body of a person near the site of the stoma, a retention member which, in use, is operatively associated with the implant, the implant and the retention member being magnetically attracted such that the discharge device is removably retained at the site of the stoma by magnetic force, and a user operable discharge control valve, able to open and close to thereby control the discharge of the fluid and material to the exterior of the body of the person when the user-operable discharge control valve is in an open condition and fluid and material are not dischargeable from the tubular member to the exterior of the body of the person when the user-operable discharge control valve is in a closed condition, wherein the annular disc or the flange member is provided with a recess at the first side of the annular disc or the flange member and adjacent to the second end of the tubular member such that the recess extends around the second end of the tubular member in a substantially circular manner and is aligned over the stoma when the tubular member is positioned in the intestine of the person, wherein an annular inflatable bladder is positioned in the recess adjacent to the second end of the tubular member to closely contact the stoma and to shield the stoma and seal around the site of the stoma at the exterior of the body of the person when the tubular member is positioned in the intestine of the person, wherein the annular disc or the flange member is arranged to bear against the exterior of the body of the person near the site of the stoma when the tubular member is positioned in the intestine of the person, and wherein the user-operable discharge control valve is located adjacent to the second end of the tubular member to discharge fluid and material from the opening at the second end of the tubular member and through the user-operable discharge control valve, when the user-operable discharge control valve is in the open condition, to exit the ostomy device to the exterior of the body of the person when the tubular member is positioned in the intestine of the person. an implant arranged, in use, to be located inside the body of a person near the site of the stoma, a retention member which, in use, is operatively associated with the implant, the implant and the retention member being magnetically attracted such that the discharge device is removably retained at the site of the stoma by magnetic force, and a

member such that the recess extends around the second end of the tubular member in a substantially circular manner and is aligned over the stoma when the tubular member is positioned in the intestine of the person, wherein an annular inflatable bladder is positioned in the recess adjacent to the second end of the tubular member to closely contact the stoma and to shield the stoma and seal around
