  • Patent number: 11986584
    Abstract: 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.

  • Publication number: 20240075247
    Abstract: A catheter may include a withdrawal lumen wall extending around a withdrawal lumen. The withdrawal lumen may have a withdrawal lumen profile. The catheter may include an infusion lumen wall coupled with the withdrawal lumen wall. The infusion lumen wall may extend around an infusion lumen. The infusion lumen may have an infusion lumen profile smaller than the withdrawal lumen profile. A flexible septum may extend between the withdrawal lumen and the infusion lumen. The flexible septum may isolate the withdrawal lumen from the infusion lumen. In another example, a blood filtration system may monitor blood flow velocity within vasculature. The blood filtration system may guide operation of a blood pump or a filtrate bump based on the blood flow velocity within the vasculature.

  • Publication number: 20240075194
    Abstract: A blood filtration system may include a blood circuit. The blood filtration system may include an adjustable cuff configured to receive a portion of a limb of a patient. The cuff may selectively engage with the limb to apply an external force to the limb. Applying force to the limb with the cuff may inhibit flow of blood within the vasculature of the limb. The system may adjust the cuff to change the force applied to the limb, for example to correspondingly change flow of blood from the vasculature to the blood circuit. The blood filtration system may include a controller. The controller may communicate with the cuff. The controller may operate the cuff to adjust the force applied to the limb of the patient.

  • Publication number: 20240066199
    Abstract: A blood filtration system may include one or more sensors. The sensors may determine physiological parameters, for instance one or more of venous oxygen saturation (Sv02) or hematocrit of a patient. The blood filtration system may include a controller. The controller may communicate with the one or more sensors. The controller may monitor the physiological parameters using the sensors. The controller may include a display module that generates content. A display may present the content. The content may include a diagnostic matrix having a diagnostic point. The display module may change the diagnostic point within the diagnostic matrix according to changes in the monitored physiological parameters.

  • Patent number: 11793709
    Abstract: A blood flow stimulator may help encourage blood flow in a limb of a patient. The blood flow stimulator may include a housing configured for sealing about the limb of the patient. The housing may include a sealable volume, and the sealable volume may receive the limb of the patient. The blood flow stimulator may include a seal, and the seal may be coupled with the housing. The seal may engage with at least a portion of the limb, for instance to segregate the sealable volume from a surrounding environment of the blood flow stimulator. The blood flow stimulator may include a conduit extending through the housing. The conduit mat help provide access to the sealable volume, for instance from the surrounding environment. In some examples, an adjustable stent is utilized to enhance blood flow within vasculature of a patient. A stent operator may change a size of the stent.

  • Patent number: 11633529
    Abstract: A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

  • Patent number: 11419969
    Abstract: A blood filtration system may to couple to an infusion pump that is external to the blood filtration system. The blood filtration system may include a blood circuit, for instance a variable-volume blood circuit. An infusion port may be in communication with the blood circuit and may receive an infusion fluid pumped by the infusion pump. A filtration pump may extract a filtrate fluid from a filter. The filtrate fluid may include filtered plasma constituents. A fluid characteristic sensor may measure one or more of pressure or flow rate of the infusion fluid pumped by the infusion pump. A controller may monitor the fluid characteristic sensor to determine a change in the pressure or flow rate of the infusion fluid. The controller may modulate a speed of the variable-speed filtration pump based on the change in the pressure or flow rate of the infusion fluid.
