A-01 Hand Incubator

Technology Benefits

ΓùÅ Extremely light: the compressor is small and weighs only 100g (0.22lb), which allows patients to be ambulatory while undergoing treatment.ΓùÅ Transparent air chamber: close observation and affected area are possible visually.ΓùÅ Active finger motion: the air chamber allows full free finger motions.

Technology Application

ΓùÅ Hand injuryΓùÅ Treating a tumor and edema at extremitiesΓùÅ Preventing deep vein thrombusΓùÅ Carpal tunnel syndromeΓùÅ LymphedemaΓùÅ Rheumatoid arthritisΓùÅ Improving the skin quality of extremities

Detailed Technology Description

Realizing that the suppression of hand swelling can inhibit both the development and progression of diseases, researchers at Nagoya University have invented the Hand Incubator. Inside the air bag, the hydrostatic pressure is kept at 40mmHg, lower than venous pressure, by an air pump powered by AA batteries. The therapeutic device reduces hand swelling drastically in four days, for example, in case of extra-venous leakage.

*Abstract

Non-steroidal anti-inflammatory drugs (NSAIDS) have been used to treat hand swelling caused by inflammatory diseases and injuries. Because NSAIDS has an inconsistent effect and sometimes causes adverse reactions, an alternative medical approach has been increasingly sought.
