发明名称 One way valve assembly
摘要 A one way valve assembly flows a sterile flowable substance from a source to an outlet orifice and prevents any backflow of contaminants through the one way valve assembly when the flowable substance ceases to flow. The valve assembly includes an elastomeric membrane which aids in preventing any backflow of contaminants when dispensing of the flowable substance is stopped.
