Disposable patient interface for intraductal fluid aspiration system

摘要

Disclosed is a disposable patient interface for an intraductal fluid aspiration system. The interface has a flexible tubular distal member for contacting the patient, and a proximal support portion forming a vacuum chamber therein. The support portion has a vacuum aperture for communication with a source of vacuum, and a retention structure for releasably mounting within a hand piece of an intraductal fluid aspiration system. The flexible member preferably has a low modulus of elasticity and a high tear strength, such that it can be stretched to fit over a rigid support without rupture.
