Can I take my wallet into the hyperbaric oxygen chamber?

You can't. Hyperbaric oxygen chamber is a special medical equipment for hyperbaric oxygen therapy. According to different pressurized media, it can be divided into air compression chamber and pure oxygen compression chamber. Do not bring anything into the hyperbaric oxygen chamber, such as wallet, watch, transistor radio, hearing aid, mobile phone, BP machine, warm cup, fountain pen, etc. ), so the leather bag can't be brought into the hyperbaric oxygen chamber.
