Claims (16)

In a rectal inserter for the treatment of rectal diseases, a pre-selected shape of a waste form retaining waste package is encapsulated with a gel-like foamable polymer constituting at least 35% (% by weight) of water, the gel being 0 After cooling below ℃, the insert is chosen to have sufficient rigidity to be inserted into the rectum.When frozen, the insert consists of a cylindrical body with a conical nose at one end and a back collar near the other. And the portion facilitates the insertion, and the collar portion prevents the initial entire insertion passage from overlying the sphincter of the rectum. The front collar portion further comprising a front collar portion located behind the nose portion and in front of the actual collar portion, wherein the front cross section of the front collar portion is a frustoconical cross section, and the rear side of the front collar portion is the length of the inserter. And a cylindrical center portion is provided on the rear side of the front collar portion and the front side of the rear collar portion by lying on a plane perpendicular to the axis. The rectal insert according to claim 1, wherein the rear collar portion is positioned at a sufficient distance in front of the rear end of the inserter so that the remaining rear portion can be gripped with a finger. 4. The rectal introducer according to claim 3, wherein at least a part of the curved surface of the rearmost end is flattened so as to lie on a plane parallel to the longitudinal axis of the inserter. 3. The rectal introducer of claim 2 wherein at least a portion of the middle portion is smaller than the maximum diameter of the inserter nose portion. 6. The rectal introducer of claim 5 wherein the diameter of the middle portion is from 50 to 25% of the maximum diameter of the nose portion. The rectal insert according to claim 2, wherein the diameter of the front collar portion is 150 to 250% of the maximum diameter of the nose portion. The rectal introducer of claim 1 wherein the gel contains at least 90% water. 8. The rectal introducer of claim 7, wherein the gel contains at least 98% water. 9. The rectal insert of claim 8, wherein the device consists of a multiblock interpolymer of acrylonitrile acrylamide having a water content of 95 to 99.7 weight percent. 2. The rectal insert according to claim 1, further comprising a pharmaceutically acceptable amount of a pharmaceutically acceptable rectal active compound. A method of using a rectal inserter for the treatment of rectal diseases is to insert a cylinder inserter of a size and shape that can be easily inserted through the sphincter of the rectum into the patient's rectum, which is a bullous polymer containing at least 35% by weight of water. Freezing at below 0 ° C. for a sufficient time to freeze free water and maintaining at least a portion of the insert outside the sphincter for at least one minute. The method according to claim 12, wherein a cylindrical device having a conical nose portion for insertion and a posterior portion of the inserter and having a collar portion smaller than the maximum diameter of the nose portion is inserted into the rectum of the hemorrhoid patient so that the entire insertion passage is through the sphincter. Using a rectal insert, characterized in that it is prevented. 13. The method of claim 12, wherein the device contains at least 90% by weight of water. 15. The method of claim 14 wherein the inserter comprises at least 98% by weight of water. 13. The method of claim 12 wherein the inserter comprises a multiblock interpolymer of acrylonitrile acrylamide with a water content of 95 to 99.7%. ※ Note: The disclosure is based on the initial application.
