ABSTRACT:
A device and a method that aids in the leveling of intra-vascular catheters from the transducer to the patient for medical procedures takes the form of a small housing which encloses a strong resilient filament which is dispensed therefrom. A bubble level vial is fixedly mounted thereupon the housing. The device thereby provides a means to acquire the desired leveling pressure readings of the intra-vascular catheter with minimal amount of effort by attaching one (1) end of the filament there to the patient and the opposing end to the transducer. When finished, the filament is retracted and stored.
