摘要： Methods and systems for measuring the pressure of a fluid. A flexible barrier separates the fluid from the pressure receiving surface of a pressure sensing device. The pressure of the fluid is transferred through the flexible barrier to the pressure receiving surface. The flexible barrier may be in abutting juxtaposition with or may be spaced apart from the pressure receiving sensing surface. In either case, the flexible barrier is coupled or held in defined relationship to the pressure sensing surface such that the pressure receiving surface will receive the substantially actual pressure of the fluid even when the pressure of the fluid is less than the ambient atmospheric pressure. Coupling of the flexible barrier to the pressure receiving surface may be achieved by any suitable means, including adhesive or the application of a full or partial vacuum between the flexible barrier and the pressure receiving surface.

摘要： Inverted peristaltic pumps and related apparatus/methods wherein one or more compressible pump tubes are formed or mounted on a core member and one or more tube compressing members move about the core member so as to compress the tube(s) and propel a fluid through the tube(s). The core member may be removeable and the pump tube(s) may be pre-mounted on the core member to form a disposable or reusable tubing cartridge. The core member or tubing cartridge may be easily inserted into and removed from the pump. In some embodiments troughs or grooves may be formed on the core member and the tube(s) may be disposed in such troughs or grooves.

摘要翻译：用于测量流体压力的方法和系统。柔性屏障将流体与压力感测装置的压力接收表面分开。流体的压力通过柔性屏障转移到压力接收表面。柔性屏障可以与压力感测表面邻接并置或与压力感测表面间隔开。在任一种情况下，柔性屏障耦合或保持与压力感测表面的限定关系，使得即使当流体的压力小于环境大气压力时，压力接收表面也将接收流体的基本上实际的压力。柔性屏障与压力接收表面的耦合可以通过任何合适的方式实现，包括粘合剂或在柔性屏障和受压表面之间施加全部或部分真空。
