A device for preparing dialysate for a dialysis machine is provided with a cartridge (9) containing salts (S), a first line (6) for supplying purified water to the cartridge (9) to form a saturated solution in the said cartridge (9), a second line (7) for supplying the said saturated solution from the cartridge (9) to the first line (6) and for mixing the saturated solution with the purified water and forming the dialysate, and a discharge line (18) for discharging the said saturated solution from the second line (7) and from the said cartridge (9) at the end of the dialysis treatment.
摘要:
The invention concerns a method for reducing a tendency toward adsorption of molecules or biological cells from solutions or suspensions on a material surface placed in contact with the solution or suspension, as well as a use of the method, and a method for the production of a material with reduced tendency toward adsorption of molecules or biological cells from solutions or suspensions, which is suitable for conducting this method. It is provided that an organic or inorganic support material with a modified surface is used as the material, and that the surface is modified by in-situ polymerization of monomers which are selected as a function of a property of the molecule or the cell, onto the surface.

摘要:
An improved method for hemodialysis employing reverse osmosis raises the pH of the blood to preserve the activity of the enzyme lysozyme to improve immune function and reduce the risk of infection in dialysis. In general, this method comprises: (1) removing arterial blood from a patient in need of hemodialysis; (2) increasing the pH of the arterial blood to a value of about 7.8 by adding a sufficient quantity of a 5% solution of sodium chloride buffered to a pH value of 7.9; (3) passing the arterial blood from step (b) through a dialyzer operating by reverse osmosis; (4) adding a pH-reducing agent selected from the group consisting of acetate buffer and dextran sulfate to reduce the pH of the blood to its normal value; (5) passing the blood from step (4) through a dialyzer operating by reverse osmosis to remove antigen; and (6) returning the blood to the patient.
摘要:
A circuit for extracorporeal treatment of a body fluid, the circuit including in serial fluidic communication an inlet for receiving the body fluid from a patient, a first pump, a first treatment device for processing the body fluid, a second pump, an outlet for returning processed body fluid to the patient; and a shunt. The shunt is upstream from the first pump and downstream from the second pump.
摘要:
Material characterized by that the material contains at least one biologically active saccharide which is covalently bound via at least one spacer to a cross-linked matrix and that the material is autoclaved.
摘要:
An extracorpeal blood circuit for removal of contrast from human blood using a filter and withdrawal filter pump and a by-pass pump. The withdrawal filter blood pump operates when a contrast bolus has been detected. Otherwise the bypass blood pump maintains physiological blood flow from the coronary sinus preventing the need for deflation and re-inflation of the balloon catheter. When contrast is detected blood the bypass blood pump is stopped to prevent contrast from leaking back into the patients circulatory system via the bypass pump and CS blood flow is maintained at its physiological blood flow resulting in the heart being oblivious to the transition by the prefilter blood pump.
摘要:
A system and method are disclosed for producing uniform size silica particles by the steps of providing preformed colloidal silica particles having a surface area, adding an alkali metal silicate and a cation exchange resin to produce a quantity of feed silica at a feed rate which is less than a nucleation rate, and increasing the feed rate as the feed silica is added wherein the feed rate is less than the nucleation rate.
摘要:
An apparatus for measuring an amount of hemodialysis is disclosed. The apparatus comprises a rotation detecting unit for detecting the number of rotations of a dialysis blood pump, the pump being rotated to pump blood; a counting unit for counting the number of rotations of the dialysis blood pump by receiving a rotation detecting signal from the rotation detecting unit; and a display unit for displaying a value counted by the counting unit to determine the entire amount of hemodialysis based on the amount of hemodialysis per unit rotation of the dialysis blood pump.
摘要:
A dialysis machine having an extracorporeal blood circuit having an arterial pipe and a venous pipe respectively connected to an inlet and an outlet of a blood compartment of a filter having a blood compartment and a dialysis liquid compartment separated by a semi-permeable membrane; means for determining a sequence of infusion of a liquid in the extracorporeal blood circuit, from at least one characteristic value (FF, TMPave, Kuf) correlated with the concentration of the blood (CE) and/or a filtration efficiency of the filter; and means for infusing the infusion solution in the arterial pipe and in the venous pipe in accordance with the determined infusion sequence.
