PURPOSE: To seal up a humor spilling from a corpse completely by using a water-absorbing resin powder containing stabilized chlorine dioxide in a humor sealing agent for the corpse.

CONSTITUTION: A water-absorbing resin powder containing stabilized chlorine dioxide is used as a humor sealing agent for corpse. The water-absorbing resin powder containing stabilized chlorine dioxide is injected into a throat by a specified amount while a specified amount of coagurant powder wrapped with a water soluble sheet is filled into nostrils and ear canels. With the application of such a treatment, a humor counter-flowed is absorbed with the throat part, the nostrils and other hole parts and a gelatinous resin swelled seals up the throat and other hole parts completely to prevent external spillage of the humor. Therefore, after the coagurant is filled into the holes of capses, there is no need for changing chemicals. The stabilized chlorine dioxide contained allows the decomposition of malodorous components, thereby lowering of pathogenic bacteria left in the humor to such an extent as to reduce the danger of infection.
