Pressure reducer for a fluid sampling device

摘要

The present invention generally relates to a pressure reducer that can regulate a fluid sample flow and decrease pressure automatically without adding any extra media. More particularly the pressure reducer has a casing having a sample inlet for receiving the fluid sample from a fluid sample source, and a sample outlet for dispensing the fluid sample to another location; a separation plate; an upper chamber; a lower chamber, wherein the casing and the separation plate cooperate to define the lower chamber and the upper chamber, and wherein the lower chamber is in communication with the upper chamber; and means for reducing pressure of a fluid dispensed through the pressure reducer.
