摘要： A method for monitoring blood vessels, the method including using a system for monitoring blood vessel functionality to look, listen and feel blood vessel functionality by imaging a patient's body to obtain blood vessel geometry, imaging a patient body to obtain a shape of a location of the patient's body using image analysis, and analyzing vibrations of the patient's body at a location of the patient's body which includes the blood vessels. A method for monitoring blood vessel functionality, the method including illuminating one or more blood vessels through a patient's skin, capturing at least one image of the blood vessels, analyzing the at least one image, and calculating a parameter associated with blood vessel functionality based upon the image analysis. Related apparatus and methods are also described.

摘要： The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.

摘要： In one aspect, a method and system for detecting a change in fluid dynamics of a fluid flowing through an extra-corporeal circuit is disclosed, which includes establishing an acoustic wave resonance across a transverse dimension of at least a portion of a line associated with the extra-corporeal circuit through which the fluid flows, monitoring a phase signal of the resonant acoustic wave, and identifying occurrence of a change in fluid dynamics of the flowing fluid when the observed phase signal of the resonant acoustic wave indicates a deviation from the expected fluid flow signature. The change in fluid dynamics can be used to indicate a venous needle dislodgement event.

摘要： A dialysis access site monitoring system may generate a treatment recommendation for treating a condition of an access site based on a video of the access site. The dialysis access site monitoring system may include an apparatus having a processor and a memory coupled to the processor. The memory may include instructions that, when executed by the processor, may cause the processor to generate video information based on a video of a dialysis access site of a patient, determine change in the number of pixels (CNP) information of the video information, the CNP information associated with movement of a skin surface of the patient due to blood flow through the dialysis access site, determine frequency domain information of the CNP information, determine a maximum-to-median power (M2) value of the frequency domain information, and determine at least one access site characteristic based on the M2 value.
