Sleeping clinic in Tokyo

Does anyone know a sleeping Clinic in Tokyo that attends in English?
I have sleeping apnea and I use my own device (CPAP) but last night it stopped working. I got in contact with the company and they said it's an old machine (9 years using it) and there's nothing I can do about it now.
I tried to schedule a consultation in a sleeping clinic in tachikawa but they denied because I need an interpreter with me for every consultation who can read and write in Japanese.
I need a consultation and another device ASAP once my apnea is moderate and I can't sleep well without it.
I know in Japan they don't sell the device. It need to be rented. But my main concern is not being able to communicate.
