Abstract
A suction device having a rotary switch is provided. A main body of the suction device is provided with a patient-end connector, an oxygen supply connector, a suction connector, a cleaning connector and a connecting portion. The rotary switch is assembled with the connecting portion and can be switched between a first position and a second position. The rotary switch is provided with two opposite suction holes. When the rotary switch is located in the first position, the two suction holes are aligned with the patient-end connector and the suction connector to thereby communicate the patient-end connector with the suction connector. When the rotary switch is located in the second position, the communication between the patient-end connector and the suction connector is shut off.
