Yes. It is possible.

D.MATE series is basically designed to connect with the Saliva Ejector and take charge of the suction.
It is designed to receive temporary assistance from the staff using HVE (metal suction) only in medical situations accompanied by bleeding such as tooth extraction and surgery.
However, in hospitals where HVE is usually used, HVE (high volume suction) can be connected and used.
HVEs of most unit chairs are also compatible, and it is recommended that you practice using it in connection with the Saliva Ejector, a small suction that is easy to use at first.
