Abstract：A new device that could both attract saliva in oral cavity and liquid in narrow structures such
as marrow cavity and root canal at the same time was developed in this paper. The device also could
make an easy switch between under two suction modes, which mainly consisted of the connecting pipe
for negative pressure suction device, connecting pipe for oral cavity suction device, suction pipe, threeway
pipe and flow cutoff valves. According to the practice results, it was needless to change the device
intra-operationally or the placement method of the suction device inside patient’s mouth. This flexibleto-
switch and convenient device was comfortable for patients, which was easy to operate for operators
and deserved wider clinical promotion.
