A device isolates a substance from blood. The substance includes particles with an effective diameter that is within a range defined by effective diameters of constituents of blood. The device comprises a first sheet of graphene including a first plurality of apertures. The first plurality of apertures are configured to pass objects with an effective diameter less than or equal to the effective diameter of the particles of the substance. The device comprises a second sheet of graphene including a second plurality of apertures. The second plurality of apertures are configured to pass objects with an effective diameter less than the effective diameter of the particles of the substance. The device may be configured to include a conduit system. The device may be configured to operate according to a reversible cycle.

An extracorporeal blood filtering machine can include a blood circuit, an effluent circuit, and a source fluid circuit and can be controlled by a controller. The extracorporeal blood filtering machine can also include access ports for connecting the source fluid circuit to the blood circuit, as well as blood sensors to detect possible issues with the extracorporeal blood filtering machine. The extracorporeal blood filtering machine can include density sensors and flow sensors that enable it to be more accurate and to operate while being transported. The extracorporeal blood filtering machine can further include a user interface and can display fluid inflow/outflow information. A medical fluid container can automatically empty after being filled. An apparatus for supporting a medical fluid container can include a hanger and an attachment member with the apparatus able to adjust to ensure the medical fluid container remains properly oriented directly under a medical fluid container scale.

A method for treating sickle cell disease comprises removing blood from a patient with sickle cell disease, treating the removed blood to decrease the fraction of sickle-prone cells in the removed blood, and reintroducing the treated blood back into the patient. The treated blood that is reintroduced back into the patient has a reduced number of sickle-prone red blood cells when compared to the blood removed from the patient. In one version, the treatment of the blood includes inducing sickling of the red blood cells prone to sickle and then separating those sickled red blood cells from the blood before reintroducing the blood back into the patient.

A blood reintroduction system can include a canister having a chamber configured to collect blood. A system may include an inlet configured to fluidically connect the chamber to a first tubing in fluid communication with an aspiration catheter. A system may include a first filter within the chamber, wherein the first filter is configured to separate blood from thrombus. A system may include a second filter downstream of the first filter, wherein the second filter is configured to separate blood from thrombus. A system may include a second tubing connected to an outlet of the chamber, wherein the second tubing is configured to reintroduce filtered blood from the chamber to a patient's vasculature.

A blood reintroduction system may include a canister configured to collect blood. The system may include an inlet configured to be fluidly connected to a first tubing in fluid communication with an aspiration system configured to apply aspiration to a vasculature of a patient. The system may include a first outlet configured to be fluidly connected to a second tubing in fluid communication with an aspiration pump. The system may include a second outlet configured to interact with a blood reintroduction device, wherein the blood reintroduction device is configured to withdraw the blood collected inside the canister. The system may include a filter positioned inside a flow path leading to the second outlet.

This invention relates to a dialysis apparatus which ultra-filters blood and to a related method of ultra-filtering blood ex-vivo.

More preferably the invention relates to haemodiafiltration using protein-losing membranes and a secondary ultrafiltration and partial re-infusion of haemodiafiltrate for increasing extraction of middle molecules and protein bound uraemic toxins and reducing albumin loss.

A method comprising obtaining a bodily fluid from a subject; contacting the bodily fluid with an adsorbent material comprising a synthetic carbon particle (SCP) to produce a first filtrate having a level of disease mediators (y); contacting the first filtrate with an adsorbent material comprising the SCP and an anion exchange resin where the ratio of SCP to anion exchange resin is in a range from about 0.1:100 to 100:0.1 to produce a second filtrate; contacting the second filtrate with an adsorbent material comprising the SCP and a cation exchange resin where the ratio of SCP to cation exchange resin is in a range from about 0.1:100 to 100:0.1 to produce a third filtrate.
