Document Type and Number:
Japanese Patent JP3478289
Kind Code:
B2
Abstract:
Provided is a diver's information processing device for notifying a diver of a change in a pressure decrease ratio, at which pressure decreases during surfacing, for the purpose of minimizing the risk of a diver's d decompression sickness and excess pulmonary expansion. In particular, when diving is performed at a high altitude, notification is made so that a pressure decrease ratio will be held lower than a pressure decrease ratio permitted at a low altitude. A diver's information processing device 1 includes means that uses a pressure meter 61 and a timer 68 to calculate a pressure decrease ratio. Moreover, the diver's information processing device 1 includes means that uses an acoustic notifier 37, a vibration generator 38, and a display panel 11 to continuously notify a pressure decrease ratio, at which pressure applied to a diver decreases during surfacing, for the purpose of minimizing the dangers of diver's surfacing.
