Abstract

A pressure sensor, for example, employed by a medical injection system for monitoring blood pressure, is isolated from relatively high pressures by a volume of a compressible medium, preferably air, or other suitable gas. The volume fills an entirety of a cavity of a pressure transducer assembly, and is enclosed between a pressure transmission interface of the assembly and the pressure sensor. The pressure transducer assembly is integrated into a fluid circuit such that the pressure transmission interface is exposed to flow through the fluid circuit. The cavity of the assembly has a configuration that allows transmission of a patient's blood pressure from the fluid circuit, via the interface and gas volume, to the pressure sensor, yet prevents transmission of the relatively high pressures, for example, injection pressures. The pressure transducer assembly may be part of a disposable fluid circuit subassembly, for example, packaged as a kit.

Description

technical field [0001] The present disclosure relates to medical injection systems and more particularly to devices and methods for isolating blood pressure monitoring sensors thereof. Background technique [0002] Medical injection systems, such as those used to deliver contrast media into a patient's vasculature for medical imaging, typically include pressure sensors integrated into the system's fluid circuit for the purpose of monitoring the patient's blood pressure during the imaging procedure. However, the pressure at which the contrast agent is injected is significantly higher (i.e., up to 1200 psi) than the monitored blood pressure (i.e., between 0 and 5 psi) By isolating the portion through which a typical blood pressure monitoring pressure sensor is protected from exposure to this high injection pressure. An example of such a medical injection system, ACIST CV i TM system, shown in figure 1 middle. [0003] figure 1 is a perspective view of an exemplary medica...
