An information display and control system that enables a fast and easy understanding and management of the status of the patient's dialysis is disclosed. Also disclosed is an information display and control system that enables a fast and easy understanding and management of the status of the patient's cardiovascular and ventilation systems. The system can control management of a patient's dialysis, as well as administration and management of a patient's medication and fluids. The display is organized by goals related to management of patient's dialysis machine, blood flow, dialyzer flow, and patient's body weight. The display is also organized by goals related to management of patient's cardiovascular system, ventilation system, and medications and fluids administration and management. Such goals include urea reduction rate, urea reduction ratio, fractional urea clearance, total urea reduction, dialysis treatment duration, hemodynamics, oxygenation, CO.sub.2 removal, medication status, and fluids status.

Method for tailoring dialysis treatment based on sensed potassium concentration in blood serum or dialysate

A method of dialysis is provided that includes sensing the concentration of potassium in a patient's blood serum, in used dialysate resulting from treating the patient, or in both. The method involves generating a sensed value of the concentration of potassium, comparing the sensed value with one or more values stored in a memory, and generating a control signal based on the comparison. Supplemental potassium solution is infused into the treatment dialysate, based on the control signal. The comparison can be made to patient-historical data, population data, or both.

20230093577 · 2023-03-23 ·

In embodiments of the invention, there is provided a dialyzer or filter comprising hollow fibers, in which blood flows on the exterior of the hollow fibers, and dialysate or filtrate may flow on the inside. The external surfaces of the hollow fibers may have properties of smoothness and hemocompatibility. The fiber bundle may have appropriate packing fraction and may have wavy fibers. Optimum shear rates and blood velocities are identified. Geometric features of the cartridge, such as pertaining to flow distribution of the blood, may be different for different ends of the cartridge. Air bleed and emboli traps may be provided. Lengthened service life may be achieved by combinations of these features, which may permit additional therapies and applications or better economics.

CORRELATION BETWEEN INTRAPERITONEAL PRESSURE ("IPP") MEASUREMENTS AND PATIENT INTRAPERITONEAL VOLUME ("IPV") METHODS, APPARATUSES, AND SYSTEMS

Methods, apparatuses, and systems for determining a correlation between intraperitoneal pressure (“IPP”) measurements and patient intraperitoneal volume (“IPV”) are disclosed. In an example, an apparatus is configured to determine a maximum fill volume of dialysate to be pumped into a peritoneal cavity of a patient. The apparatus also determines a plurality of iterations to achieve the maximum fill volume and a volume of the dialysate to be pumped for each of the iterations. For each iteration, the apparatus causes a dialysis machine to pump the dialysate to the peritoneal cavity based on the determined volume for that iteration, records IPP measurement output data from a pressure sensor, records or determines a total accumulated fill volume, and creates a data point for a personalized patient model corresponding to a correlation between the IPP measurement output data and the total accumulated fill volume.

METAL-ORGANIC FRAMEWORKS FOR p-Cresyl SULFATE ADSORPTION

Provided herein is a method for removing uremic toxins from blood is provided. The method includes exposing blood to iron-based metal-organic frameworks; and allowing the metal-organic frameworks to bind a least one uremic toxin in the blood.

Noninvasive hydration monitoring

Novel tools and techniques for assessing, predicting and/or estimating effectiveness of hydration of a patient and/or an amount of fluid needed for effective hydration of the patient, in some cases, noninvasively.

CLOSED CIRCULATION SYSTEM TEST APPARATUS FOR BLOOD PURIFICATION DEVICE USING WHOLE BLOOD

A closed circulation system test apparatus independently sets the amount of a liquid such as a dialysate for a blood purification device, facilitates management of operations of multiple pumps, and is capable of evaluating performance for removing wastes in blood and lifespan performance of membranes. The closed circulation system test apparatus includes: a blood sending line for sending blood from the blood bag to the blood purification device via a blood pump; a blood returning line for sending blood exiting from the blood purification device to the blood bag via a resistance imparting means; a filtrate line for sending the filtrate exiting from a dialysate outlet of the blood purification device to the replacement fluid container via a filtrate pump; and a dialysate line for sending, via a dialysate pump, dialysate or replacement fluid from the replacement fluid container to a dialysate inlet of the blood purification device.

Blood-purification-treatment support system

A blood-purification-treatment support system is capable of making an accurate judgement of whether or not any treatment conditions for blood purification treatment should be changed. The blood-purification-treatment support system is capable of supporting blood purification treatment. The system includes a storage device that stores patient-specific patient data that are acquired on a plurality of days including at least no-treatment days on which blood purification treatment is not conducted, an estimating device that compares the patient data for the plurality of days stored in the storage device with one another and estimates a pre-treatment patient state regarding blood purification treatment, and a judging device that judges from the pre-treatment patient state estimated by the estimating device whether or not any treatment conditions for blood purification treatment should be changed.
