Abstract
A pressure reading assembly including a housing defining a conduit configured to transmit bodily fluid therethrough and a receiving tube having a first opening and an inner cylindrical surface. The pressure reading assembly further includes a sensing apparatus which includes a sensor disposed on a substrate and an engagement member including a generally columnar sealing member configured to engage an inner cylindrical surface of a receiving tube within the housing connected to the substrate about the sensor. The sealing member defines an axial bore extending from a proximal end to a distal end and includes an outer sealing surface defining one or more engaging elements configured to non-adhesively engage the inner cylindrical surface of the receiving tube to resist removal of the sensor assembly so that a pre-sterilized sensor assembly can be removed from a clean sealed packaging and joined directly with the housing.
