Abstract

Disclosed are systems for a body-fluid (e.g., blood) treatment. A blood treatment system comprises a reservoir for holding a batch of blood from a patient; a first conduit for conveying blood from a vascular access of the patient during a first stage and for returning treated blood to the vascular access during a third stage, the first conduit having only a single lumen; a filter for performing extracorporeal treatment on blood passing therethrough by removing waste molecules and/or fluid; a recirculating blood processing loop connecting the reservoir to the filter; a first blood pump for conveying blood in the recirculating blood processing loop; and a controller configured to control the first blood pump to repeatedly recirculate blood from the reservoir through the filter during a second stage between the first and third stages.

Abstract

The present disclosure provides a manual extracorporeal blood treatment device, the device comprising: a filter for performing an extracorporeal treatment on blood passing therethrough by removing waste molecules and/or fluid; a first conduit for conveying blood from a vascular access of a patient and for returning treated blood to the vascular access, the first conduit having a double lumen which is attach to the vascular access of the patient at a first end and a first syringe coupled to the first conduit via a first valve at the second end, wherein the first valve is between the first syringe and the filter; a second conduit connected to the first conduit at the double lumen, wherein the second conduit is connected to the filter and to the first valve; a second valve between the vascular access of the patient and the double lumen; and a second syringe and optionally a third syringe each connected to the filter.

Abstract

The disclosure provides methods and systems to improve the extracorporeal processing and treatment of blood comprising conveying a volume of blood via a first conduit of a patient to a blood chamber at a first flow rate, conveying the blood from the blood chamber through an extracorporeal therapeutic device at a second flow rate to perform an extracorporeal treatment on the blood and returning the treated blood to the blood chamber, and returning the blood from the blood chamber to the patient at a third flow rate via a second conduit, wherein the second flow rate is decoupled from both the first and third flow rates.

Abstract

The disclosure provides a blood treatment method, comprising: (a) conveying a volume of blood via a first conduit from a vascular access of a patient to a blood chamber at a first flow rate, the first conduit having only a single lumen; (b) conveying the blood from the blood chamber through a filtration device at a second flow rate, wherein the filtration device is part of a legacy system, to perform an extracorporeal treatment on the blood and returning the treated blood to the blood chamber; and (c) returning the blood from the blood chamber to the vascular access of the patient at a third flow rate via the first conduit, wherein the second flow rate is decoupled from, and independent of both the first and third flow rates.

Abstract

The disclosure provides a manual blood or body fluid treatment system comprising first and second reservoirs for holding a batch of blood from a patient and a filter for performing an extracorporeal treatment on blood passing therethrough by removing waste molecules and/or fluid. The first reservoir is constructed to be displaced vertically relative to the second reservoir and vice versa, such that a height difference between the first and second reservoirs causes blood or body fluid to flow between the reservoirs due to gravity.
