Abstract: The present invention is generally related to a suction aspirator for suctioning out liquids during surgical interventions. The subject suction uses a built-in interrupting valve as a means to control simultaneously the vacuum suction flow and the vacuum suction noise. The suction noise is a disturbing noise generated when a vacuum suction flow passes through the suction device. The said valve mechanism is simply constructed and easily operated by one finger of the same hand that is holding the suction device. The said valve assembly is so incorporated that it is unbiased to any working position with the suction device. The said suction device is so constructed that it can be sterilized and can be used with sterile technique required for surgery.
