Abstract: Disclosed is a device for facilitating placement of a central line in a patient, said device comprising: a housing having proximal and distal ends and a central portion therebetween, said housing having an upper portion and a lower portion; a handgrip provided on the proximal end of the housing, said handgrip having at least one of a channel and a through hole extending from the proximal end to the central portion, wherein the channel or through hole is sized to receive a guidewire; a feeder tip receiver provided on a proximal end of the handgrip in communication with the channel or through hole in said handgrip; a stabilizer provided on the lower portion of said housing; a luer slip tip provided on the distal end of the housing, said luer slip tip having a mounting portion for attachment to a needle hub, said luer slip tip having a lumen aligned with the channel or through hole in said handgrip; and a wire slide platform provided on the central portion of the housing.

Abstract: A positioning fixture for use with an ultrasound transducer comprising: a housing having a planar, generally rectangular bottom surface having two parallel long edges and two parallel short edges; a pair of long sidewalls, one said long sidewall attached to each of said two parallel long edges; a guide release attached to one of said two parallel short edges; a long axis needle guide attached to another of said two parallel short edges; and a receptacle cooperatively defined by said pair of long sidewalls, said quick release and said needle insertion guide, said receptacle sized to accommodate the ultrasound transducer.

Abstract: A compensation device for a valve compensates for expansion of a valve stem and/or inertial effects during operation of the valve. The compensation device is preferably integrally provided with the valve. The compensation device includes a first plate rigidly connected to the body of the valve and a second plate movably coupled to the first plate. The second plate is rigidly coupled to the operator assembly housing that houses and controls the movement of the second end of the valve stem, so that movement of the second plate relative to the first plate moves the operator assembly relative to the valve body to compensate for expansion of the valve stem and/or inertial forces. The first plate and second plate remain in radial alignment during the relative movement. One or more biasing elements, such as spring assemblies, are used to connect the first plate and the second plate to bias the plates in a default position, absorb forces and allow for movement of the second plate relative to the first plate.
