A blood pressure prediction method and an electronic device using the same are provided. The method includes the following steps. A training data set is collected. A first blood pressure prediction model is established according to the training data set. Hemodialysis parameter data of a target patient is received, wherein the hemodialysis parameter data includes a first hemodialysis parameter at a previous time point and a second hemodialysis parameter at a current time point. A hemodialysis parameter variation amount between the first hemodialysis parameter and the second hemodialysis parameter is calculated. The hemodialysis parameter variation amount is provided to the first blood pressure prediction model to generate a prediction blood pressure variation associated with a next time point. An operation is performed according to the prediction blood pressure variation of the target patient.

The present invention provides a method for hemodiafiltration which applies dialysate gradient across a multi-chambered hemodiafiltrator having a plurality of compartmentalized tubular dialysate chambers. An acidic dialysate with urea at a concentration is applied to a first dialysate chamber. A less acidic dialysate with a lower concentration of urea than those for the first dialysate chamber is applied to a second dialysate chamber. A basic dialysate with no urea but with ammonia at a concentration up to a concentration detected in normal human blood is applied to a last dialysate chamber. The concentrations of urea for the first and second dialysate chambers decrease over time to zero prior to conclusion of hemodiafiltration.

A method of identifying a type of a filter, which has at least one retentate side and at least one permeate side separated from one another by at least one filter medium, includes generating a pressure in a fluid, in particular in a liquid, on the retentate side or on the permeate side via a pressure source. The method then includes switching off the pressure source, and measuring a pressure development in the fluid over time subsequent to the switching off of the pressure source.

Systems and methods for cleaning and disinfecting a medical therapy device that delivers any one of hemodialysis, hemodiafiltration and hemofiltration. The system has a base module that has at least one segment of a controlled compliant flow path and at least one pair of jumpered ports configured on the base module. One or more components have connections connectable to the jumpered ports of the base module to provide for fluid communication between the segment of the controlled compliant flow path in the base module and a flow path defined by the one or more components. The base module is connected to the one or more components that define a flow path configurable for carrying out in part at least one function performed during any one of hemodialysis, hemodiafiltration or hemofiltration.

Manifolds suitable for use in hemodialysis, hemofiltration, hemodiafiltration, and peritoneal dialysis are provided. One or more of the manifolds can include a manifold body and an external tube.

The pneumatic manifold includes a plurality of pneumatic passageways and a plurality of pneumatic connectors. The pump and valve engine includes a plurality of valve chambers, at least one pump chamber, and a plurality of pneumatic connectors mated sealingly and releasably with the pneumatic connectors of the pneumatic manifold. The pump and valve engine also includes a plurality of fluid connectors. The fluid manifold includes a plurality of fluid pathways and a plurality of fluid connectors mated sealingly and releasably with the fluid connectors of the pump and valve engine.

An extracorporeal blood treatment apparatus is provided comprising a filtration unit (2) connected to a blood circuit (17) and to a dialysate circuit (32); a control unit (12) is configured for calculating a sodium concentration value for the blood; the estimation of the sodium concentration includes the sub-step of calculating the sodium concentration value as an algebraic sum of a main contribution term based on the isoconductive sodium concentrate and of an offset contribution term based on a concentration of at least a substance in the dialysis fluid chosen in the group including bicarbonate, potassium, acetate, lactate, citrate, magnesium, calcium, sulphate and phosphate.

A method and apparatus are provided for a hemodiafiltration delivery module that is used in conjunction with a UF controlled dialysis machine to enable hemodiafiltration therapy to be performed. The advantage is that one can fully utilize a current functioning dialysis machine to perform a hemodiafiltration therapy as opposed to purchasing a completely new machine that offers this capability.

A microwave therapy apparatus and method for blood cancer treatment is disclosed. The microwave therapy apparatus for blood cancer treatment includes a plurality of porous anodic aluminum oxide (AAO) filters or a plurality of porous glass filters provided in a dialyzer of a hemodialysis apparatus; a nanoflower filter provided downstream of the plurality of porous anodic aluminum oxide (AAO) filters or the plurality of porous glass filters in the blood tube; and an RF absorber provided downstream of the nanoflower filter to attract cancer cells thereto by generating a frequency of a predetermined band, wherein the blood, from which the cancer cells have been removed by an RF frequency and which includes normal blood cells that passed through the nanoflower filter, is circulated and supplied to a blood tube connected to a vein of the body of the blood cancer patient.

A connection apparatus for sealing to a pathway of a mounting structure includes a body; and a port including a threaded portion extending from the body and a non-threaded portion extending from the threaded portion, the non-threaded portion carrying a gasket, the gasket positioned along the non-threaded portion such that the mounting structure to which the connection apparatus is mounted contacts the gasket prior to the threaded portion engaging a mating threaded portion of the mounting structure, the port providing fluid communication between the body and the pathway of the mounting structure. The body may be that of a valve that supplies any of air, water or oil as an operating fluid to, for example, inlet and outlet valves and a pump chamber of a medical fluid pump of a medical fluid delivery machine.
