An extracorporeal blood processing system comprises a plastic molded compact manifold that supports a plurality of molded blood and dialysate fluidic pathways along with a plurality of relevant sensors, valves and pumps. A disposable dialyzer is connected to the molded manifold to complete the blood circuit of the system. The compact manifold is also disposable in one embodiment and can be detachably installed in the dialysis machine.

Methods and Systems for fluid balancing in a dialysis system

The specification discloses a portable dialysis machine having a detachable controller unit and base unit. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface, a heater in thermal communication with the planar surface, and a sodium sensor in electromagnetic communication with the planar surface. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.

Portable dialysis machine

Disposable apparatus and kit for conducting dialysis

Systems and method are disclosed for determining a concentration of an analyte in a fluid (e.g., blood). The system can draw blood from a patient and deliver the blood to a sample cell. A particular component of the fluid (e.g., plasma) may be separated and/or positioned such that the concentration of the analyte is measured in the particular component of the fluid (e.g., plasma). The sample cell can include a sample container that has two window pieces. The system can have a fluid passage having a tip configured to mate with a multi-lumen catheter without leaking. The multi-lumen catheter can have proximal and distal ports. A fluid pressure system can be configured to periodically draw fluid from vasculature through a proximal intravascular opening and the proximal port while maintaining a low pressure and/or flow rate to thereby reduce risk of reversing the fluid flow in a vessel and drawing infusates upstream into another intravascular opening.

Fluid analysis cuvette with coupled transparent windows

Disclosed is an apparatus for analyzing the composition of bodily fluid. The apparatus can include a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient and a pump unit in operative engagement with the fluid handling network. The pump unit can have an infusion mode, in which the pump unit is operable to deliver infusion fluid to the patient through the patient end, and a sample draw mode, in which the pump unit is operable to draw a sample of the bodily fluid from the patient through the patient end. The apparatus can include a spectroscopic analyzer positioned to analyze at least a portion of the sample; a processor in communication with or incorporated into the spectroscopic analyzer; and stored program instructions executable by the processor to obtain measurements of two or more properties of the sample.

Bodily fluid composition analyzer with disposable cassette

A fluid handling module that is removably engageable with a bodily fluid analyzer is provided. The module may comprise a fluid handling element, and a fluid component separator that is accessible via the fluid handling element and configured to separate at least one component of a bodily fluid transported to the fluid component separator. The fluid handling element may have at least one control element interface.

Fluid handling cassette

A reagentless whole-blood analyte detection system that is capable of being deployed near a patient has a source capable of emitting a beam of radiation that includes a spectral band. The whole-blood system also has a detector in an optical path of the beam. The whole-blood system also has a housing that is configured to house the source and the detector. The whole-blood system also has a sample element that is situated in the optical path of the beam. The sample element has a sample cell and a sample cell wall that does not eliminate transmittance of the beam of radiation in the spectral band.

Analyte monitoring systems and methods

A fluid handling system for use in bodily fluid analysis. The system comprises a first fluid handling module configured to interface with a main instrument. The first fluid handling module has a first fluid handling network and the first fluid handling network includes an infusate passage and an infusion fluid pressure member suitable for moving fluid within the infusate passage. The fluid handling system also has a second fluid handling module separate from the first module which is configured to interface with the main instrument. The second fluid handling module has a second fluid handling network and at least one sample analysis cell which is accessible via the second fluid handling network. The first and second modules are configured to interconnect and provide fluid communication between the first and second fluid handling network and the sample cells.

Fluid handling cassette system for body fluid analyzer

Fluid analysis system

In certain embodiments, a sampling assembly is for use with a main analyzer. The main analyzer is configured to sense an analyte in a body fluid obtained from a patient through a first fluid passageway extending from the main analyzer. The sampling assembly includes an instrument portion separate from the main analyzer and including at least one sensor. The instrument portion is removably engaged with the first fluid passageway. The at least one sensor is in sensing engagement with the first fluid passageway such that the at least one sensor can sense a property of a fluid within the first fluid passageway.
