    摘要： The present invention involves, in some embodiments, mechanisms and methods of occluding collapsible tubing with an occluder to prevent fluid flow therethrough. In some embodiments, a tube occluding mechanism is disclosed that includes a bendable occluding member for creating a force that can be applied to a collapsible tube to occlude the tube. In some embodiments, the collapsible tube can be an inlet/outlet tube on a removable pumping cartridge that is coupled to a reusable pump drive component when the system is in operation. In such embodiments, the occluding mechanism can be attached to the reusable component and can be used to block fluid flow to and from the pumping cartridge. In some embodiments, the occluding member can comprises a spring plate which can create a force to occlude tubing when in a relaxed, unbent configuration, and which can be bent to unocclude the tubing. In some preferred embodiments, in a default configuration of the tube occluder mechanism (when no external force is applied to the occluding member) the tubes are occluded, so that the tube occluder mechanism provides a fail-safe configuration preventing fluid flow to and from a pumping cartridge to which the tubes can be connected.

    摘要翻译： 在一些实施例中，本发明涉及用闭塞器封闭可收缩管道以防止流体流过其中的机构和方法。 在一些实施例中，公开了一种管闭塞机构，其包括用于产生能够施加到可收缩管以封闭管的力的可弯曲闭塞构件。 在一些实施例中，可折叠管可以是可拆卸泵筒上的入口/出口管，其在系统运行时与可重复使用的泵驱动部件联接。 在这样的实施例中，闭塞机构可以附接到可重复使用的部件，并且可以用于阻止流入和流出泵送的流体。 在一些实施例中，闭塞构件可以包括弹簧板，弹簧板可以在处于松弛的，未弯曲的构造中时产生阻塞管道的力，并且可以弯曲以排除管道。 在一些优选实施例中，在管堵塞机构的默认配置（当外力不对阻塞构件施加时）管被封闭，使得管封堵器机构提供故障安全配置，防止流体流入和流出 泵可以连接到管道上。

    摘要： An apparatus comprises a detector, a pressure sensor and a processor. The detector is operable to detect light that is scattered by an aerosol that is associated with a pressure. The pressure sensor is operable to measure the pressure. The processor is coupled to the detector and to the pressure sensor, and is configured to receive at least a signal from the detector and the pressure sensor. The processor is further configured to use the received signals to calculate a volume of the first aerosol, and to output an output signal associated with the calculated volume. The various measurements can be repeated and compared, and the output signal can be a feedback signal for metering subsequent amounts of the aerosol, based on the comparison.

    摘要： A method is provided for regulating fluid pump pressures by detecting an elevation differential between a fluid flow control device and the distal end of a fluid line in communication with the fluid flow control device. A fluid flow control device, for instance a peritoneal dialysis device, is at a first height, a distal end of a fluid line is at a second height, and a valved outlet, when open, affords communication between the fluid flow control device and the distal end of the fluid line. The elevation differential is correlatable with a pressure measurable during a calibration procedure provided as a part of the methodology.
