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.

Systems and methods for autonomous intravenous needle insertion are disclosed herein. In an embodiment, a system for autonomous intravenous insertion include a robot arm, one or more sensors pivotally attached to the robot arm for gathering information about potential insertion sites in a subject arm, a medical device pivotally attached to the robot arm, and a controller in communication with the sensors and the robot arm, wherein the controller receives the information from the sensors about potential insertion sites, and the controller selects a target insertion site and directs the robot arm to insert the medical device into the target insertion site.

A vein heating assembly includes a sleeve that has a first portion which is hingedly coupled to a second portion. The first portion is positionable in an open position to have a patient's arm positioned therein and the first portion is positionable in a closed position to surround the patient's arm. A plurality of nozzles is each integrated into the sleeve. A plurality of heating elements is each coupled to the sleeve to warm the patient's arm when the heating elements are turned on thereby increasing blood flow in the arm for enhancing the appearance of veins. A steam unit is integrated into the sleeve to produce steam that is delivered onto the patient's arm for increasing blood flow in the arm for enhancing the appearance of veins.

The present invention is an arm restraint used in dialysis primarily when the fistula is located at or near the elbow. The restraint supports the arm and allows a limited amount of movement of the restrained arm to mitigate discomfort during a dialysis procedure, while simultaneously allowing unrestricted blood flow in the supported arm. The restraint includes an adjustable fastener that allows the restraint to be attached to the upper arm in a loose and adjustable manner. The restraint includes a cover at its lower end that allows a limited degree of arm movement. It also includes an open upper area that enables access to the arm for placement and adjustment of dialysis syringes and associated tubing.
