A tubing expansion device (20) is adapted to be advanced axially, without rotation, through tubing (10) to be expanded. The device (20) comprises a body (22) and a plurality of expansion members (30,32,34) mounted on the body (22), the expansion members (30,32,34) being independently radially movable. The expansion members may be rotatable, or may be non-rotating.
摘要:
A method of expanding tubing comprises the steps: providing a length of expandable tubing; locating an expansion tool, such as a cone, in the tubing; and applying impulses to the tool to drive the tool through the tubing and expand the tubing to a larger diameter. The tubing may be located downhole and may have a solid wall or a slotted wall.

A system for medical tubing detection and management could include an infusion manifold housing having at least one fluid channel therethrough. At least one fluid input port could be provided in the infusion manifold housing and could be configured to connect fluidically to illuminated medical tubing and communicate with the at least one fluid channel through the infusion manifold housing. A fluid output port could be provided in the infusion manifold housing and be configured to be in fluidic communication with the at least one fluid channel through the infusion manifold housing. At least one photosensor could be provided in the infusion manifold housing and be configured to receive light from the illuminated medical tubing; and the fluid output port could be configured to connect fluidically to fluid output tubing.

An illuminated medical tubing set that provides visual indications of characteristics relating to the type and operating status of the tubing. An illuminated tubing set system generally comprises an optical element, a fluid conduit, and a power source. In general, the fluid conduit is used to transmit fluid in a critical care environment. The power source interfaces with the optical element. The optical element is configured to illuminate the tubing set after being powered by the power source. Optionally, the illuminated tubing set can further comprise a pressure sensor and a microcontroller. Additional sensors, such as to monitor other characteristics of the tubing, fluid, or surrounding environment, can also be included. For example, an occlusion sensor, temperature sensor, or flow sensor, or any combination thereof, can be included.

Folding assemblies for vehicles are described. In one aspect, a folding headrest assembly for a vehicle seat comprises a headrest having a frame. A pivot joint is coupled to the frame for rotatably supporting the headrest with respect to the vehicle seat between an upright position and a folded position. A support rod extends from the pivot joint and is configured for coupling to the vehicle seat. The headrest receives the pivot joint and a portion of the support rod, and the headrest defines an opening configured to provide clearance for the support rod as the headrest is rotated about the pivot joint relative to the support rod. A closeout member coupled to the support rod circumscribes at least an exposed portion of the pivot joint that is aligned with the opening of the headrest.

A flow control device comprises a housing, a flow restriction member, and a flow control ring defining a flow control port which is configured to receive the flow restriction member. The flow control ring is configured so as to be sealingly mounted onto a base pipe. The flow restriction member is at least partially inserted into the flow control port so as to at least partially define a predetermined flow restriction through the flow control ring. The housing is sealingly mounted on the flow control ring. The flow control device may be mounted on a base pipe. The flow control device may be used for controlling fluid flow, in particular, though not exclusively in oil and/or gas wells. A flow control system and method are also disclosed
