ABSTRACT:
A valve and method for preventing backflow of bacteria and other unhealthy substances in a medical suctioning apparatus. The valve defines a chamber and has an outlet and an opposed inlet. The valve provides a tortuous path that effectively limits backflow of bacteria and other unhealthy substances. The valve further includes a diffuser proximate the outlet to direct backflowing fluids to travel the full length of the tortuous path. The valve is used between a medical suctioning unit and a patient-contacting part such as an ejector, evacuator, or yankauer.
