Reusable fluid pressure transducer monitoring apparatus
First Claim
1. An apparatus for monitoring fluid pressure, comprising:
- a reusable base section;
a disposable dome section detachably connected to the base section, the dome section defining a fluid pathway;
pressure sensing means disposed in the reusable base section for producing electrical signals proportional to fluid pressures sensed in the fluid pathway; and
visual indicator means disposed in the base section for providing a visual indication of usage of the apparatus within a predetermined number of uses.

Abstract
An apparatus for monitoring fluid pressure includes a reusable base section, and a disposable dome section detachably connected to the base section. The disposable dome section defines a fluid pathway and includes a dome viewing segment in fluid communication with a flush segment and a stopcock segment. A pressure transducer sensor is disposed in the reusable base section and is adapted to produce electrical signals proportional to fluid pressures sensed in the fluid pathway. A usage indicator can be disposed in the base section to provide a visual indication of usage of the apparatus within a predetermined number of uses. A calibration port can be provided in the base section to allow for simple calibration by the user without violating the sterility of the apparatus. The ability to reuse the base section with the sensor component reduces the cost of the apparatus, while the disposability of the dome section with the fluid pathway ensures sterility for each use.
