Abstract: A therapeutic thermal pack with built-in seal and insulation functions for preserving the thermal condition of its thermal module. The thermal pack comprises a plurality of thermal module for thermal therapy, an insulation cover comprising a fastening means for attaching the thermal module to a body part, and a closing means for enclosing the thermal module inside the insulation cover for preserving the temperature of the thermal module. When it is configured for storage and carry, this thermal pack can maintain its therapeutic condition for an extended time period without using an additional insulation. It can thus be conveniently carried to the sports fields using any regular bag. When the pack is used for a treatment, the built-in insulation functions minimize the heat exchange between the thermal modules of the thermal pack and the surrounding environment and thus prolong the treatment time of the thermal pack.

Abstract: The present invention provides a process for preparing; a high water-containing elastomer medical catheter and a urinary catheter prepared by the process. The process comprises a) heating a mixture consisting of polyvinyl alcohol, water, sulfoxide and linear alkane, in a sealed vessel with agitating; b) pouring the resulting homogeneous fluid into a mould; c) solidifying the fluid by cooling; d) releasing the solidified fluid from the mould; and e) heat-treating the resulting medical catheter and washing with a polar organic solvent. The medical catheter and the urinary catheter of the present invention have excellent lubricity.
