An integrated disposable cartridge for dialysis or ultrafiltration treatment of blood includes integral pressure sensors. Sensors are embedded in the blood filter on the cartridge to measure the pressure of blood or other fluids in the filter.
摘要:
A filter for an extracorporeal blood circuit including: a bundle of hollow fibers having an end section encased in a potting material, wherein the end section further comprises a stem of fibers and potting material and an annular disk of the potting material extending radially outward from the stem, wherein the annular disk of the potting material is substantially wider than the stem, the stem protrudes from the disk and the stem includes a side surface extending along a length of the stem; an end surface of the stem substantially perpendicular to the length of the stem and including open ends of the fibers distributed throughout the end surface including open ends proximate to a perimeter of the end surface; a filter housing through which extends the bundle, the filter housing comprising a tubular section and a first end section and a second end section at opposite ends of the tubular section, wherein the annular disk is seated in the first end section and the stem is narrower than the tubular section along the length of the stem; a filter header cap mounted on the first end section of the filter housing, wherein the filter header cap includes an inlet connectable to a blood line and an open end, the filter header cap including a cap side surface abutting the stem side surface, and the second end section connectable to a blood line.
摘要:
A tapered extracorporeal blood tube having at least a first end of the tube with a large diameter, a narrow diameter section of the tube, and a tapered tube transition section between the first end and the narrow section. The tapered blood tube reduces the overall blood flow volume in the circuit.
摘要:
Ionizing bars for delivering charged carriers to charge neutralization target objects may include an ion emitter for establishing an ion cloud of charge carriers in response to application of an ionizing voltage. Disclosed bars may also include a reference electrode that presents a non-ionizing electric field to urge ions to move away from the ion emitter. The disclosed bars may also include a manifold. The manifold may receive and divide gas into plural gas streams directed past the ion emitter in a pattern to thereby urge charge carriers toward the target. The manifold may have plural apertures with nozzled inserts received therein. At least some of the inserts may have at least one aperture through which gas may flow and the nozzle inserts may collectively direct the divided gas streams away from the manifold and toward the target in one or more predetermined patterns.

摘要:
A format for accessing content such as a full-length movie from an optical disc uses an XML Description File stored on the disc to generate one or more screens that a user employs to access the content. To increase the efficiency of accessing data, data files that describe the content of the disc are located near the beginning of the video zone whereas larger data files, such as presentation files, are located at the end of the video zone. To reduce the possibility of incompatibilities between commands, a limited set of application program interface (API) commands is defined for use in an XML Description File. To maximize the vertical data recorded on the disc when the source aspect ratio is high, two, independent horizontal and vertical distortion factors are used. The audio and video tracks are interleaved into 1000 millisecond blocks and are demultiplexed by the application player during playback.
摘要:
Method and apparatus for the extracorporeal treatment of blood by utilizing a peripherally inserted dual lumen catheter assembly for the continuous removal and return of blood for renal replacement treatment, in particularly, treatment of congestive heart failure and fluid overload by ultrafiltration. A catheter is inserted in a peripheral vein and maneuvered upward through the vascular system to access the reservoir of blood in the large or great veins for continuous blood withdrawal and treatment. Air-tight connectors are incorporated in the catheter assembly to overcome the untoward effects of negative pressure in blood withdrawal.

摘要:
An extracorporeal blood circuit is disclosed for withdrawing, filtering and returning blood from peripheral blood vessels. The blood passage in the circuit extends through a withdrawal tube connected to a catheter in a peripheral vein, a filter, one or more pressure sensors and return tube also connected to a catheter in a peripheral vein (which may or may not be the same vein as used for the withdrawal tube). The blood passage is air free, and has smooth passage walls which promoted continuous and uniform flow of the blood through the circuit.
摘要:
A multi-sectional linear ionizing bar with at least four elements is disclosed. First, disclosed bars may include at least one ionization cell with at least one axis-defining linear ion emitter for establishing an ion cloud along the length thereof. Second, disclosed bars may include at least one reference electrode. Third, disclosed bars may include a manifold for receiving gas or air from a source and for delivering same past the linear emitter(s) such that substantially none of the gas/air flows into the ion cloud. Fourth, disclosed bars may include means for receiving the ionizing voltage and for delivering same to the linear emitter(s) to thereby establish the ion cloud. In this way, disclosed ionizing bars may transport ions from the plasma region toward a charge neutralization target without inducing substantial vibration of the linear emitter and without substantial contaminants from the gas/air flow reaching the linear emitter.
