Abstract
The present invention is an apparatus and method for invasive bodily fluid pressure measurements using a pressure sensing assembly that is partially reusable. An embodiment includes a system for measuring a bodily pressure level having a support structure that includes at least one reusable pressure transducer that has a sensing face positioned on an exterior portion of the support structure, and a disposable pressure plenum having an inlet in fluid communication with a selected location within the body of a living being that is configured to be removably and slidably engaged with the support structure.

34. A method of measuring a selected bodily pressure in a patient, comprising:
-
providing a support including at least one reusable sensor having an exposed sensing surface; releasably securing a disposable pressure plenum to the support, the disposable pressure plenum having a pressure compliant surface disposed thereon and in contact with the sensor; fluidly coupling the plenum to a selected location within the patient; and measuring a bodily pressure at the selected location using the sensor. - View Dependent Claims (35, 36, 37, 38, 39, 40)

41. A method of measuring a selected bodily pressure in a patient, comprising:
-
providing a first reusable support including a first engagement location physically connected to a second reusable support having a second engagement location wherein at least one of the first reusable support and second reusable support has an exposed sensing surface; releasably securing a first disposable plenum that forms at least a portion of a fluid path extending from the patient to the first disposable plenum, the first disposable plenum being removably securable to the first engagement location and fluidly isolating the fluid path from the first engagement location when the first disposable plenum is secured to the first engagement location, wherein the first disposable plenum has a pressure compliant surface disposed thereon and in contact with the sensor; fluidly coupling the first disposable plenum to a selected location within the patient; and measuring a bodily pressure at the selected location using the sensor. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
