Devices and techniques for estimating/detecting a location of a mixing cloud in a vessel of a subject may be provided. The techniques may include positioning a first tubular member within the vessel and flowing blood through a first lumen from a proximal end to a distal end of either the first tubular member or a second tubular member in a direction retrograde to a direction blood is natively flowing in the vessel. The techniques may include determining a plurality of blood-related characteristics of blood flowing in the vessel, such as arterial blood oxygen saturation values, each determined from blood acquired at a different axial position along the first tubular member, and/or pressure values, each determined from a pressure sensor at different axial positions along an exterior surface of the first tubular member. The techniques may include estimating a location of the mixing cloud based on the blood-related characteristics.

A modular blood-gas exchange system is provided. The system may include a first oxygenator manifold, a second oxygenator manifold, and a plurality of blood-gas exchange cartridges removably coupled to the first and second oxygenator manifolds. The first oxygenator manifold may include a plurality of first blood ports. The second oxygenator manifold may include a plurality of second blood ports. Each blood-gas exchange cartridges may be configured to allow blood and a sweep gas to flow through the removably attachable cartridge, and may be configured to allow a gas molecule to transfer between the sweep gas and the blood.

A device, system, and method of use are provided. The device includes a cannula having a lumen extending therethrough, an inflow cage coupled to one end of the cannula and an outflow cage coupled to the other end of the cage. The inflow cage includes an inflow check valve that is configured to allow blood to flow into the lumen only when a pressure inside the lumen is less than a pressure of blood external to the inflow check valve. The outflow cage includes an outflow check valve that is configured to allow blood to flow out of the lumen through at least one outlet only when a pressure in the lumen is greater than a pressure of blood external to the outflow check valve. A catheter is operably coupled the outflow cage. A pump capable of generating positive and negative pressures is operably coupled to the lumen.

An article shipment system 100 includes an automated warehouse 1, a picking area 2, a consolidation area 4, and a control system 5. The control system 5 alternately provides, to the automated warehouse 1, a transfer command to transfer a target mount with a higher picking workload from the automated warehouse 1 and a transfer command to transfer a target mount with a lower picking workload from the automated warehouse 1 to transport multiple first mounts to the picking area 2. The target mount is a first mount, among the first mounts, loaded with articles of a specified type included in a target article-specific order information group. The target article-specific order information group is a group of pieces of article-specific order information included in part of multiple pieces of order information among pieces of article-specific order information included in the multiple pieces of order information.

Disclosed are an anthracene derivative with a specific structure and an organic electroluminescent device including the anthracene derivative. The organic electroluminescent device includes a light emitting layer employing the anthracene derivative as a host compound and a polycyclic aromatic derivative with a specific structure as a dopant compound. The use of the host and dopant compounds allows the organic electroluminescent device to have a long lifetime and significantly improved low-voltage characteristics.

A blood pump is provided, that is configured to be disposed within the inferior vena cava (IVC). The blood pump may include a cannula having an inlet and an outlet, and an impeller configured to cause blood to flow through the cannula from the inlet towards the outlet. The inlet may be configured to be disposed at or near where the renal veins connect to the IVC. An occlusive balloon, anchor(s), and/or fixate(s) may be operably coupled to a surface of the cannula. A film may be coupled to anchor(s) and/or fixate(s), to restrict the flow of blood past the film. Restriction of blood flow around the cannula creates a pressure gradient between the inlet and outlet in the IVC, allowing for effective decongestion of the venous compartment distal of the inlet. The anchor(s) and/or fixate(s) may prevent vein collapse during operation due to increased negative pressures.

Embodiments of brazing systems are disclosed. In one embodiment, a brazing system (100) includes a controller circuit board (controller) (260) having a processor (264) and a memory (262). The system also includes a fuel gas input (222), a fuel gas output (224), an oxygen/air gas input (216), and an oxygen/air gas output (218). The system further includes a touch screen display (202) and a foot pedal (610), each operatively connected to the controller (260). The controller (260) is configured to store multiple jobs of flame presets in the memory (262). Any job can be called up from the controller (260) and the flame presets can be cycled through in response to tapping the foot pedal (610). Each job corresponds to a sequence of joint brazings to be performed on a braze assembly and includes a plurality of selectable flame presets. Each flame preset defines a flame setting based on a flow rate of a fuel gas and a flow rate of an oxygen/air gas.

Disclosed is a blood pump rotor, and an intravascular blood pump that utilizes the rotor. The blood pump rotor is configured to rotate around an axis of rotation, and comprises a distal portion and a proximal portion. The distal portion includes a rotor hub, which tapers in a distal direction. The rotor hub has at least one blade extending outward from the rotor hub. Further, a distal end of said rotor hub extends distally beyond a most distal portion of the at least one blade. The proximal portion, which is connected to the distal portion, has permanent magnets arranged so as to form a Halbach array generating a magnetic field having a magnetic flux in a proximal direction that is greater than a magnetic flux in a distal direction, said first magnetic flux being greater than said second magnetic flux. The Halbach array comprises an alternating arrangement of axial magnetized magnets and circumferential magnetized magnets. At least one secondary blade is provided on a proximal surface of at least one circumferential magnetized magnet, wherein the at least one secondary blade extends axially in a proximal direction.

A polycyclic aromatic compound or a condensed multimer thereof, according to the present invention, is employed in an organic layer in an organoelectroluminescent device, thereby enabling the implementation of an organoelectroluminescent device having high efficiency and a long lifespan, and thus the present invention may be industrially useful in various display devices such as a flat panel display device, a flexible display device, a monochromatic or white flat panel lighting device, and a monochromatic or white flexible lighting device.
