    摘要: The dose of dialysis in terms of urea clearance is marginal in many hemodialysis patients, and metabolic acidosis as determined by the pre-dialysis serum HCO3 level is common. A dialysate that included citric acid rather than acetic acid as acidifying agent provides superior performance properties. Citrate-containing dialysate was used exclusively in 22 hemodialysis patients. Initially, only 8 of the 22 patients had a pre-dialysis serum HCO3>23 mEq/L (lower limit of normal), however, after 12 weeks of dialysis using the citrate-containing dialysate, the serum HCO3 normalized in 15 patients (p=0.0001, Chi-square). Dialysis variables were kept constant in 19 of the patients, who also used and reused the same dialyzer model throughout. In these patients, the initial average urea reduction ratio (URR) was 68.5±5.9%, and after treatment with the citrate dialysate disclosed herein, this ratio had increased to 73±5.3% (p

    摘要: The present invention constitutes dialysate formulations that are suitable for use in preparing dialysate solutions for use in batch and/or proportioning systems and for improving dialysis efficiency by reducing or preventing clotting of the dialysis flow paths. The dialysate chemical formulations for one batch of dialysate comprise an acid concentrate stored in a first vessel, and a citrate-containing bicarbonate concentrate stored in a second vessel. The contents of the first and second vessels are emptied into a dialysate preparation tank and mixed with water to form a batch quantity of dialysate solution. Alternately, a dry acid and/or a dry citrate-containing base concentrates are dissolved separately in measured quantities of water to form liquid concentrates which are then used in conjunction with a proportioning machine to generate on-line a final dialysis solution stream.

    摘要: A system and method for generating a secret key to facilitate secure communications between users. A first and second and a function between the two monoids are selected, the function being a monoid homomorphism. A group and a group action of the group on the first monoid is selected. Each user is assigned a submonoid of the first monoid so that these submonoids satisfy a special symmetry property determined by the function, a structure of the first and second monoids, and the action of the group. A multiplication of an element in the second monoid and an element in the first monoid is obtained by combining the group action and the monoid homomorphism. First and second users choose private keys which are sequences of elements in their respective submonoids. A first result is obtained by multiplying an identity element by the first element of the sequence in a respective submonoid. Starting with the first result, each element of the user's private key may be iteratively multiplied by the previous result to produce a public key. Public keys are exchanged between first and second users. Each user's private key may be iteratively multiplied by the other user's public key to produce a secret key. Secure communication may then occur between the first and second user using the secret key.

    摘要: A method of performing regional citrate anticoagulant dialysis of a patient's blood includes flowing blood from and back to the patient through an extracorporeal circuit including a dialyzer having semi-permeable dialysis membranes and a dialysate chamber surrounding the membranes. The method further includes flowing a dialysate containing calcium and citrate through the dialysate chamber of the dialyzer and introducing citrate into the patient's blood upstream of the dialyzer, whereby the patient's blood is dialyzed. The method can further include predicting the concentration of systemic ionized calcium in the blood of the patient at any point in the dialysis treatment or post-dialysis, such as by a mathematical model. The method can further include statistically correcting the preliminary predicted post-dialysis concentration of systemic ionized calcium in the patient's blood to provide a final predicted post-dialysis systemic ionized calcium concentration. The method can further include statistically correcting the preliminary predicted systemic ionized calcium concentration for any time point during the dialysis treatment to provide a final predicted systemic ionized calcium concentration for that time point.

    摘要: A method of controlling diffusive sodium transport from the dialysate solution to the blood of a patient undergoing hemodialysis treatment or from the blood to the dialysate solution includes calculating SNa+average, an average of the patient's historic serum sodium concentrations, and estimating SNa+estimated, the patient's pre-dialysis serum sodium concentration, based on the average of the patient's measured historic pre-dialysis serum sodium concentrations, SNa+measured. The method enables adjusting DNa+, the sodium concentration of the dialysate solution, based on the average of the patient's historic serum sodium concentrations, SNa+average, if needed, and performing the dialysis treatment of the patient using a dialysate solution containing a sodium concentration DNa+.
