Abstract
Abstract A device for self-administered treatment of hemorrhoids and other rectal disorders generally comprises an outer vessel including a hollow, thin-walled, flexible elongated tubular body portion having an inner closed end and an outer closed end and dimensioned for manual rectal insertion of the inner end, and having an enlarged stop portion at the outer end to prevent rectal insertion of the outer end and to insure proper positioning during use. The inner end has a portion of larger circumference to prevent expulsion of the device during use by anal spincter action. Chemical components within the outer vessel produce an exothermic reaction. An inner vessel, disposed within the outer vessel, contains at least one of the chemical components, and being facturable upon flexion of the outer vessel, provides for mixture of the chemicals. The device is intended for insertion into the anal canal to raise the temperature of the wall surface to approximately 45° C. In a preferred embodiment dissolution of a salt (calcium chloride) quickly raises the temperature of the device to the desired temperature and hydration of an oxide (calcium oxide) maintains this temperature. The hydation reaction is throttled by mixing the calcium oxide with a hydrophobic agent (lauric acid) and compressing the mixture, and by the presence of the dissolved ionic salt.
