Systems and methods for measuring fluid pressure within a disposable IV set connected to a fluid supply pump

摘要

Systems and methods of measuring pressure of fluid in a disposable IV set connected to a fluid supply pump is disclosed. At least one sensing arrangement coupled to the fluid supply pump is provided. A chamber having a movable element is provided, the movable element configured to move in response to changes in fluid pressure within the disposable IV set and thereby cause a change in a sensed measurement variable associated with the sensing arrangement without contacting the sensing arrangement. A measuring signal indicative of the sensed measurement variable is generated. The fluid pressure within the disposable IV set is determined based on the measuring signal.
