1. A regulator for flow modulation during fluid collection, comprising:
a fluid transfer device comprising a tubular sidewall and a flexible member, wherein the flexible member is integrally formed within or secured to the tubular sidewall, wherein the tubular sidewall and the flexible member define a fluid passageway, wherein the flexible member comprises a first face that faces an inner surface of the fluid passageway, wherein the tubular sidewall defines the inner surface of the fluid passageway directly opposite the first face of the flexible member, wherein the flexible member comprises a second face opposite the first face, wherein the second face is located outside the fluid passageway, and wherein the first face and the second face are configured for movement with respect to the fluid passageway upon exposure of the fluid transfer device to a differential pressure resulting in the fluid passageway having a linear flow through architecture, wherein the flexible member is configured to at least partially collapse toward the inner surface of the fluid passageway to restrict a flow area of the fluid passageway upon exposure of the fluid transfer device to the differential pressure, wherein a contact member is provided on the first face of the flexible member, wherein the contact member extends from the first face of the flexible member toward the inner surface of the fluid passageway directly opposite the first face of the flexible member, and wherein, during an initial spike of vacuum pressure when the fluid transfer device is exposed to the differential pressure, the contact member abuts the inner surface of the fluid passageway to form a sealing point therewith to stop fluid flow through the fluid passageway.
