摘要:
A medical fluid therapy method includes: (a) establishing a communication link between a kidney dialysis/blood treatment machine and at least one remote pump controller; (b) using the link to synchronize operation of at least one pump housed integrally with the machine with at least one pump located remotely from the machine; (c) enabling an operator to enter a net fluid transfer amount; and (d) controlling the pumps to at least substantially achieve the entered amount.
摘要:
Systems, apparatus and methods that allow external infusion, IV or administration pumps to be synchronized with the internal pumps for a medical fluid therapy machine are provided. The system reduces the time and effort needed to calculate, set-up, enter and maintain flowrates of various fluids, maintained internally or externally with respect to the medical fluid therapy machine. The system also automatically follows therapy requirements, for example, a requirement that one pump/fluid be running/flowing for another pump/fluid to be enabled to run/flow. The system further automatically adjusts for variations in flowrate of one fluid with respect to another. In short, the system provides a more “hands-off”, safe and effective method and apparatus for medical fluid therapy fluid delivery.
摘要:
A flow management system for extracorporeal blood treatment application helps to ensure proper balance of incoming and outgoing fluids by precise balancing of relatively small balance chambers. The invention employs combinations of features that help to ensure accuracy including underfilling of the waste flow side of a fixed volume chamber and mechanical connections to synchronize valves and pumps.
摘要:
An infusion control device controls infusion of a liquid in an extracorporeal blood circuit having an arterial pipe connected to an inlet of a blood compartment of a filter and a venous pipe connected to an outlet of the blood compartment. The arterial pipe is also connected to a pre-dilution pipe of an infusion circuit, and the venous pipe is also connected to a post-dilution pipe of said infusion circuit. The infusion control device regulates and distributes an infusion flow rate in the arterial and venous pipes based on a monitoring of quantities that are directly correlated with the operating conditions of the filter.
摘要:
A first flow path is defined within a first panel that forms a part of an extracorporeal fluid circuit. A second flow path is defined within a second panel that also forms a part of the extracorporeal fluid circuit. The first and second panels are oriented in a fluid processing cartridge for mounting as an integrated unit on a fluid processing machine and for removal as an integrated unit from the fluid processing machine.

摘要:
An extra-corporeal blood purification device includes a blood filter, and elements for measuring at least one parameter affected by filter resistance to liquid flow, elements for determining at least a threshold value of the parameter, elements for comparing the parameter with the threshold value, exchange control elements for calculating the distribution between the respective flow rates through connecting ducts, capable of reducing the difference between the value of the measured parameter and the threshold value.
摘要:
Automated systems and methods for withdrawing and replacing fluids in a patient are disclosed. The system withdraws blood from a donor or patient, separates the blood into two or more components and collects the separated component. A replacement fluid capable of at least partially providing the biological function of the separated component is infused into the patient.
摘要:
A method and apparatus for preventing and treating septicemia in patient blood is provided. The extracorporeal system includes an antimicrobial device to inactivate at least 99% of bloodborne microorganisms, a hemoconcentrator/filtration unit to remove approximately 50-75% of target molecules from the patient blood and a filter unit to remove target molecules from patient blood from the sieved plasma filtrate. Target molecules are produced by microorganisms, as well as by the patient's cells. These molecules include endotoxins from Gram negative bacteria, exotoxins from Gram negative and Gram positive bacteria, as well as RAP protein mediator from Staphylococcus aureus, and cell mediators such as tumor necrosis factor-alpha, and interleukin 1-beta, interleukin 6, complement proteins C3a and C5a, and bradykinin.
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.
