The present disclosure is related to a method and system for providing personalised haemodialysis for subject. The method includes obtaining concentration of electrolytes and of metabolic content in blood sample flowing into and out of dialyser through first blood bypass tube and second blood bypass tube, respectively. The first and the second blood bypass tube are arranged in first sensor and second sensor. Similarly, concentration of electrolytes and metabolic content in dialysate fluid flowing into and out of dialyser through first and second dialysate tube, respectively. The first dialysate tube and second dialysate tube are arranged to pass through third sensor and fourth sensor. Further, variations are identified in concentration obtained for electrolytes and metabolic content in blood sample with respect to concentration obtained for electrolytes and metabolic content in dialysate fluid, respectively. Thereafter, removal of electrolytes and metabolic content is performed from blood sample.

An article configured to warm and monitor a patient during a dialysis treatment, the article includes one or more heating elements. The article also includes one or more sensors configured to monitor a condition of the patient during the dialysis treatment. The article also includes a fabric portion configured to receive the one or more heating elements and the one or more sensors and position the one or more heating elements and the one or more sensors on the patient during treatment. The article also includes a transmitter configured to transmit information from the one or more sensors to a dialysis machine and an electrical connector configured to provide power to at least one of the one or more heating elements and the one or more sensors.

The present invention relates to devices, systems, and methods for controlling the concentration of potassium in dialysate in a closed loop potassium control system. The devices, systems, and methods can be compatible with any dialysis system including sorbent-based dialysis systems, single pass dialysis systems, or other multi-pass dialysis systems. The systems can use closed loop potassium control over potassium concentration in the dialysate to reduce the probability of patient arrhythmias. The potassium concentration can be controlled and personalized to a patient using certain predetermined patient parameters. Related systems, algorithms, and control systems are contemplated for optimizing the potassium concentration in the dialysate.

A thrombectomy system incorporates analytical instrumentation to determine the aspirate characteristic (the fluid contents of the thrombectomy catheter) and subsequently selects a thrombectomy operating mode appropriate to the current aspirate characteristic. Aspirate characteristics include: (1) blood, which is slowly aspirated, (2) thrombus which is rapidly aspirated to waste, (3) clot, which is systematically aspirated and (4) clog, which is systematically cleared. A differential viscometer is disclosed for a broad array of applications including thrombectomy, as well as industrial, automotive, environmental and scientific. A variable aperture catheter is disclosed which permits selective aspiration and infusion in either the axial or radial directions.

A peritoneal dialysis (PD) fluid line set includes a fluid line configured to carry spent dialysate to a drain receptacle and a chemical testing device disposed along the fluid line. The chemical testing device is configured to detect a presence of a substance in the spent dialysate as the spent dialysate flows past the chemical testing device, and the chemical testing device is configured to provide a visual indicator of the presence of the substance in the spent dialysate.

An apparatus for measuring pressure within a fluid path includes a housing defining the structure of the apparatus. The housing includes a fluid path that extends through the housing and allows a fluid to pass through the housing. The apparatus also includes a first volume chamber that is in fluid communication with the fluid path and has a first volume chamber opening, and a second volume chamber with a second volume chamber opening that is less than the first volume chamber opening. A diaphragm separates the first volume chamber from the second volume chamber and fluidly disconnects the second volume chamber from the fluid path. The diaphragm deforms based upon the pressure within the fluid path. The apparatus also includes an interface that is connectable to a pressure sensor, and the second volume chamber is in fluid communication with the interface.

Techniques and systems for determining an arteriovenous (AV) fistula maturation in a patient may include detecting a first series of oxygen saturation levels of the patient at a central venous catheter (CVC) associated with a first series of hemodialysis treatments prior to the AV fistula implantation are described. The AV fistula may then be implanted in the patient. A second series of oxygen saturation levels of the patient at the CVC associated with a second series of hemodialysis treatments may be detected. The second series of oxygen saturation levels may be compared to a stable threshold mature AV fistula oxygen saturation level. Among other determinations from the comparison, in response to one or more of the second series of oxygen saturation levels meeting or exceeding the stable threshold mature AV fistula oxygen saturation level, determining the AV fistula is mature. Other embodiments are described.

A monitoring system for cardiac operations with cardiopulmonary bypass comprising: a processor operatively connected to a heart-lung machine; a pump flow detecting device connected to a pump of the heart-lung machine to continuously measure the pump flow value and send it to the processor; a hematocrit reading device inserted inside the arterial or venous line of the heart-lung machine to continuously measure the blood hematocrit value and to send it to the processor; a data input device to allow the operator to manually input data regarding the arterial oxygen saturation and the arterial oxygen tension; computing means integrated in the processor to compute the oxygen delivery value on the basis of the measured pump flow, the measured hematocrit value, the preset value of arterial oxygen saturation, and the preset value of arterial oxygen tension; and a display connected to the processor to display in real-time the computed oxygen delivery value.

The present invention relates to a perfusion cannula for placement of an access, having a cannula wall and a perfusion lumen which is surrounded by the cannula wall and in which a fluid flow can flow through the perfusion cannula, wherein the perfusion cannula furthermore comprises at least one sensor lumen and at least one sensor device, in particular an ECG sensor, which is arranged at least partially in the sensor lumen. As a result, it is possible to provide a particularly reliable perfusion cannula with improved functionality and for reliable handling, in particular in conjunction with an extracorporeal lung support system.

The invention relates to a secure system for the perfusion of a body liquid, enabling a final control of compatibility of a treatment with the patient and/or the medical situation previously diagnosed by a doctor, in a simple, efficient and energy-saving manner. To this end, the system includes a fluidic circuit of a perfusion having a perfusion catheter, a perfusion tubing and a container for the determined perfusion product to be perfused to a patient. The system is also configured to take a body liquid sample from a patient and to analyze and compare the body liquid sample to the determined perfusion product so as to control the flow of the perfusion product.
