Flow meter and related method
A system for regulating fluid flow having a processor configured to reduce image noise is provided. The system includes an image sensor to capture an image of the drip chamber. The processor captures the image of the drip chamber using the image sensor, performs an edge detection on the image to generate a first processed image, and performs a Boolean-operation on a pixel on a first side of an axis of the first processed image with a corresponding pixel on a second side of the axis of the first processed image to generate a second processed image.
ENCAPSULATED SYSTEM FOR PRESSURIZED FLUID PROCESSES
Fluid management systems for handling pressurized fluid connect various subsystems or subunits without the need to use reinforced tubing. The system utilizes one or more segments of unreinforced conduit that are encapsulated at various points along a length of the segment with one or more rigid encapsulating members. The unreinforced conduit may be made a disposable element while the rigid encapsulating members may be re-used. In one aspect, the encapsulating member may include a two-part valve body that surrounds and encapsulates a portion of the unreinforced conduit. In another aspect, the encapsulating member may include a two-part jacket that surrounds and encapsulates a portion of the unreinforced conduit. The two-part valve bodies and two-part jackets may be joined at various points within the system as part of the overall flow system.

CHANNEL SELECTOR VALVE
A multi-channel selector valve includes a housing, a rotor at least partially disposed within the housing and rotatable about an axis of rotation, the rotor having a first cam surface, and a stator at least partially disposed within the housing. The housing includes a plurality of flow controllers arranged about the axis of rotation of the rotor, each flow controller including an aperture, and a blocking member disposed adjacent to the cam surface, the blocking member selectively movable relative to the aperture to open and permit flow through the aperture.
MULTIPLE-TUBE PINCH VALVE ASSEMBLY
A multi-tubing pinch valve assembly including a receiving space defined between a pinch protrusion and tubing contact body. The multi-tubing pinch valve assembly is moveable between a retracted state and an extended state. In the extended state, multiple tubes disposed in the receiving space are pinched, restricting flow therethrough. In the retracted state, multiple tubes are capable of being loaded into and/or out of the receiving space.

Device for clamping a hose line, medical treatment device with a device for clamping a hose line, and method for monitoring a device for clamping a hose line
The invention relates to an apparatus for clamping a hose line, comprising a clamping body 19, an electromagnetic actuation unit 20 for the clamping body and a monitoring device 23 which monitors the position of the clamping body, the actuation unit 20 comprising a coil 21 for generating a magnetic field. The invention also relates to a medical treatment apparatus, in particular an apparatus for extracorporeal blood treatment, comprising an apparatus 14 for clamping a hose line, and to a method for monitoring an apparatus for clamping a hose line. The monitoring device 23 has a measurement device 24 for measuring an electrical property of the coil 21 that is dependent on the position of the clamping body 19, and an evaluation device 25 for determining the position of the clamping body 19 on the basis of the electrical property of the coil. Given that only one electrical property of the coil 21 is monitored, an additional mechanical component is not required for monitoring. In a preferred embodiment of the invention, the inductance L of the coil 21 is an electrical property that is dependent on the position of the clamping body 19. A measurement device 25 is provided in order to measure the inductance L of the coil.
