IV catheter introducer with retractable needle

An IV catheter introducer having a retractable needle holder and a tubular plunger that are held by a detent structure in a preferred positional relationship prior to and during insertion of the catheter. Following insertion, the plunger is pushed past the detent structure, permitting a compressed spring to force the needle holder upwardly into the plunger. A vented end cap in the plunger permits rapid venting of air displaced during retraction of the needle holder. The needle holder includes a flash chamber that is easily viewable through a clear plastic housing. Wings are provided on the housing to facililate one-handed operation of the device. A method for assembling the subject catheter introducer is also disclosed.

Video-based detection and recognition system and method of vehicles

The invention discloses a video-based detection and recognition system and a method of vehicles. The system comprises a target characteristic database module, a moving target detection module and a vehicle recognition module. A vehicle sample target characteristic database is built to store data by virtue of the target characteristic database module. After a moving target zone is detected by the moving target detection module, the vehicle recognition module builds a search window and recognizes vehicles. The system and the method resolve the technical problems of poor vehicle distinguishing capability and low distinguishing accuracy of the video-based vehicle detection under the condition of obvious background movement, vehicle adhesion, vehicle occlusion and the like in the prior art. The video-based detection and recognition system and the method of the vehicles have the advantages of excellent vehicle distinguishing capability and high accuracy.

Catheter device

A catheter is provided that includes an elongated body extending from a proximal end to a distal end thereof. The body has a first wall and a second wall that define at least one lumen. The first wall includes at least one outwardly extending ridge. The at least one ridge defines a lateral opening in the first wall that extends to the distal end of the body. In an alternate embodiment, the elongated body has an outer wall and an inner wall that define a first lumen having a first port, and a second lumen having a second port, that extend along the body. The outer wall includes a plurality of ridges outwardly extending from the outer wall and disposed adjacent to the first port of the first lumen. The plurality of ridges are configured and spaced apart to support a body vessel such that occlusion of the first lumen and the second lumen is prevented.

Blood treatment catheter and method

Disclosed are various embodiments of a hemo-dialysis catheter in which the aspirating port at the end of the aspirating tube is distal of the infusion port or ports at the end of the infusion lumen. The infusion port or ports are arranged circumferentially so that the infused filtered blood is a substantially 360° jet of fluid with a substantial radial component. This jet of fluid serves to abrade the occlusive material that is composed of fibrin and other components that grows down along the outer wall of the catheter that would otherwise tend to block off the ports. Stopping occlusion growth at the zone of the infusion ports prevents further growth distally to the aspirating port and protects the aspirating port from being blocked by the growth of occlusion.

Antihelix-conforming ear-mount for personal audio-set

InactiveUS7536008B2Light weightMinimizes pneumatic leakageMicrophonesInterconnection arrangementsAntihelixTotal occlusion
A light weight and comfortable ear mount for a personal audio-set is disclosed. The ear mount conforms with the anti-helix of a wearer's ear thereby operating substantially as a compression spring between the wearer's anti-helix and tragus to operably secure the personal audio-set in place. In a preferred embodiment, the ear mount is substantially kidney-shaped and includes an opening to prevent the total occlusion of the ear canal by the personal audio-set. Alternatively, the ear mount includes a loop of material sized to operably engage the anti-helix of the wearer's ear. The ear mount is preferably reversible to allow it to be placed in either the wearer's left or right ear.

Method for Deployment of a Stent Graft

The method includes providing a delivery device. The delivery device comprises a support stent, an inner sheath, and an outer sheath. The support stent is slidably positioned about a wire lumen. The support stent has a proximal end and a distal end, and is expandable from a compressed delivery configuration to an expanded configuration. The inner sheath is retractably positioned about the support stent with the support stent in the delivery configuration. The anchor stent is slidably positioned about the inner sheath and is deployable from a compressed delivery configuration to a deployed configuration. The outer sheath is retracted to expand the anchor stent from the delivery configuration to an expanded configuration. The anchor stent is deployed in the body vessel. The inner sheath is retracted to expand the support stent from the compressed insertion configuration to an expanded configuration.

3 menu display

A device and method of rendering visual information combine image information like video and secondary image information, like graphics. The image information and the secondary image information are processed for generating output information to be rendered in a three-dimensional space. The output information is arranged for display on a 3D stereoscopic display having a true display depth range (44). The processing includes detecting an image depth range of the image information, and detecting a secondary depth range of the secondary visual information. In the display depth range (44), a first sub-range (41) and second sub-range (43) are determined, which first sub-range and second sub-range are non-overlapping. The image depth range is accommodated in the first sub-range and the secondary depth range is accommodated in the second sub-range. Advantageously graphics and video are displayed in true 3D without video objects occluding graphical objects.

Multi-finger mouse emulation

One embodiment of the present invention sets forth a technique for emulating left, right, and center mouse button functionality for a multi-touch input device to provide end-users with full mouse functionality. Various finger to mouse button mapping techniques are used to specify the left, right or middle mouse buttons. A single finger is used for tracking while a second finger or thumb is used to activate or deactivate one of the mouse buttons. Multi-finger mouse emulation enables more precise cursor control, while avoiding occlusion of the cursor and end-user fatigue, thereby improving the overall end-user experience.
