Abstract
A negative-pressure accessory of a negative-pressure instrument is connected to an instrument body through a wire and a suction pipe. The negative-pressure accessory includes a cup body and a pressure-sensing module. The cup body includes a joint connected to one end of the suction pipe. The pressure-sensing module is disposed in the cup body and communicating to the instrument body. When the instrument body sucks an air in the cup body, the pressure-sensing module senses the air flowing therethrough to obtain a negative-pressure signal in the cup body, and the pressure-sensing module transmits the negative-pressure signal to the instrument body to determine a negative-pressure value in the cup body.
