Research developing a waterproofing case to enable measurement using small medical apparatus during scuba diving

The purpose of this study was developing a waterproof case to make it possible to measure physiological information during scuba diving using a small medical apparatus. Clinical data about the physiological information during scuba diving can be obtained by using this development waterproof case. This potentially allows development of an index to measure diving safety. The following conclusions were obtained from the results of this study. 1) The waterproofing of the developed case was confirmed as satisfactorily high. Moreover, it was confirmed to have satisfactory capacity to resist pressure. 2) In order to maintain a neutral lift for the developed waterproofing case, it is necessary to attach a 2kg weight. 3) The regulator attached to the waterproofing case showed that there was no squeeze on the human body.
