Abstract: A "cold" gas sterilization process that operates at temperatures below 80.degree. C. in a temperature range that is generally considered nonsporicidal. The process is capable of sterilizing with gaseous hydrogen peroxide at extremely low concentrations in a gas phase, such as 0.5 mg/L. The widely used process of "cold" sterilizing with ethylene oxide is typically run at a gas concentration of 630 mg/L and 55.degree. C. Apparatus is also disclosed for use of this process in "cold" sterilization of contact lenses.

Abstract: A method of sterilizing the surfaces of articles such as medical intruments and other products by exposing such surfaces to hydrogen peroxide gas at temperatures below 80.degree. C. in a temperature range that is generally considered nonsporicidal.

Abstract: A flexible pad with interconnecting internal passages for circulating a hot or cold liquid for treating a patient. The pad has an improved internal flow pattern that includes a set of partitions that separate the pad into a plurality of major fields that are connected in series to insure that liquid flows to all areas, i.e. fields, of the pad even when such pad is in folded condition. Within each field is a series of passages forming a crisscross waffle grid pattern for random liquid flow in many directions within each field to reduce the chance of blocking liquid circulation through the pad when it is in folded condition.

Abstract: A medical pad with a pair of laminated plastic film panels defining a passage therebetween for circulating hot or cold water. The pad has a patient contact panel of long staple absorbent cellulosic fibers, and these fibers are anchored directly to a plastic film panel or are intertwined and locked to similar fibers that are so anchored. For moist therapy, the patient contact pad is wetted immediately before use.

Abstract: Heat transferring liquid is pumped by a peristaltic pump from a reservoir through a heat exchanger to a disposable applicator pad through flexible conduits. The heat exchanger is provided with thermoelectric diodes which, under control of electronic circuitry, may absorb heat from or transfer heat to the liquid. Further, the control circuitry permits adjustment of the temperature of the applicator pad, whether hot or cold.
