摘要： Devices, systems, and methods for medication infusion are described herein. In some embodiments, a system includes a patient access subassembly, a first fluid reservoir, a second fluid reservoir, and an assembly. The assembly can have a first configuration in which the patient access subassembly is in fluid communication with the first fluid reservoir via a first tube, a second configuration in which the first fluid reservoir is in fluid communication with the second fluid reservoir, and a third configuration in which the first fluid reservoir is in fluid communication with the patient access subassembly via a second tube, the first fluid reservoir fluidically isolated from the first tube in the third configuration.

摘要： 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.

摘要： Embodiments are described for separating collecting components from a multi-component fluid such as whole blood. Some embodiments provide for controlling the amount of a component, such as platelets, introduced into a separation chamber to ensure that the density of fluid in the separation chamber does not exceed a particular value. This may provide for collecting purer components. Other embodiments may provide for determining a chamber flow rate based on a concentration of a component in the multi-component fluid, which may then be used to determine a centrifuge speed, to collect purer concentrated components.

摘要： A dialysis system may include a blood circuit, a cassette, a subsystem having a processor, a sensor, and a blood pumping mechanism, a housing in which the subsystem is arranged, a movable support arranged in the housing and configured to hold the sensor and/or the blood pumping mechanism of the subsystem, a cassette holder configured to removably receive the cassette, and a loading system. The loading system may be configured to move the movable support, e.g. by an axial movement, to a first position and to a second position relatively to the housing while the cassette holder is fixedly arranged in the housing. The loading system may have an electric motor controlled by the processor, a drive assembly coupled to the electric motor, and a guiding assembly configured to cooperate with the drive assembly.

摘要： Systems and methods are provided for separating blood into two or more components for collection of red blood cells, plasma, or both red blood cells and plasma. A blood separation system includes a blood separation device and a fluid flow circuit configured to be mounted to the blood separation device. The blood separation device includes a centrifugal separator and a spinning membrane separator drive unit, with the blood being separated into its constituents by the centrifugal separator. Separated plasma may be collected following separation by the centrifugal separator or may first be conveyed from the centrifugal separator into the spinning membrane separator drive unit to separate cellular blood components from the plasma prior to collection of the filtered plasma. The cellular blood components filtered from the plasma may be retained in the circuit as a waste product or may be flushed out of the circuit to a recipient.

摘要： An apparatus for treating a hemorrhaging wound and returning blood to the body includes at least one vacuum hose; tubing to return blood to the body; a reservoir to temporarily contain the blood, an ejectable filter between the vacuum hose and the reservoir, a temperature regulator to regulate the temperature in the reservoir; at least one pressure regulator connected to the at least one vacuum hose; a vacuum pump connected to the at least one pressure regulator, and an infusion pump connected to the tubing to return blood to the body. Blood is returned to the body via multi access catheter and/or consistent with present and future rapid infusion procedural methods that could change according to severity of injuries and the need for alternate vascular access points and/or infusion delivery protocols.

摘要： Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.
