摘要:
A delivery device includes first and second housing portions that selectively engage and disengage. A reservoir on one housing portion operatively engages a drive device and/or a needle inserting device on the other housing portion. Upon proper engagement of the housing portions, the reservoir operatively couples to the drive device and/or the needle inserting device. A first magnet on the first housing portion and a second magnet (or a magnetically-attractive material) on the second housing portion are positioned to magnetically interact with each other, upon operative engagement of the housing portions. A third magnet on the second housing portion may be opposed to the first magnet to help align the housing portions for connection. A magnet-responsive device may be on one or both housing portions to detect alignment and/or connection of the housing portions.
摘要:
An insertion device, generally used with an infusion set, including a needle being adapted for puncturing at one end and including at the opposite end a hub. The hub includes a handle part and a guard part that are capable of securing the needle through the use of locks. Locking structures are used to secure the insertion device in a position where the needle is covered in a locked position, avoiding unintended contact with the needle.
摘要:
A needle guard for an insertion device generally used with an infusion set. The needle of the insertion device is commonly adapted for puncturing at one end and including at the opposite end a hub. The needle guard includes an opening adapted to receive the insertion device and a locking mechanism adapted to secure the insertion device in the needle guard. By pushing the needle hub into the needle guard for disposal, barbs on the needle hub will mate with undercuts on the inside of the needle guard and secure the needle hub in a position where the needle is covered, preventing unintended contact with the needle.
摘要:
An infusion set for subcutaneous delivery of an infusant. The infusion set may include a base removably attachable to an infusion site and a connector temporarily lockable to the base. The connector can engage the base in a plurality of orientations. The connector locks into the base after at least partial rotation of the connector about the base. The connector may include flexible arms which unlock the connector from the base. The base includes a cannula for insertion through the infusion site. The connector includes a tubing for passing the infusant. The infusant is subcutaneously passable from the tubing through the cannula when the connector is attached to the base. The infusion set may also include a hub removably attachable to the base that includes a needle that extends through the base and the cannula and a guard removably attachable to the base opposite the hub for surrounding the needle.

摘要:
Systems and methods for controlling combustion emission parameters associated with a gas turbine combustor. The method can include providing an optical path through a gas turbine exhaust duct, propagating light along the optical path, measuring exhaust species absorption of the light within the gas turbine exhaust duct, and controlling at least one of the combustion parameters based at least in part on the measured exhaust species absorption.
摘要:
Low VOC viscosity reducer (LVVR) compounds useful for reducing the viscosity of plastisol compositions. The plastisol compositions are combined with a viscosity reducing compound which is derived from the reaction of at least one of 2,2,4-trimethyl-1,3-pentane diol (TMPD) and 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate (TXOL) with at least one of a carboxylic acid or a fatty acid.
摘要:
A suspension beam with a captured axle is described, including a top and bottom plate, a pivot mount, and a spring mount, and side plates. Optional embodiments include an axle sleeve, multiple top and bottom plates, a u-shaped member in place of the side plates. The pivot mount includes a bush housing and a bush housing clamp. The side walls may be recessed, flush or outboard with respect to the top and bottom plates. The top and bottom plates are directly attached to the axle or axle sleeve, and to the pivot mount.

Provided are wedging and clamping mechanisms for securing an axle to a suspension member. The suspension member has a integral axle shell for seating the axle to be attached. An axle wedging shell is provided which mates to the axle shell via aligning angled grooves and flanges which, as the flanges are forced into the grooves, creates a significant clamping force trapping the axle in place. The orientation and placement of angled grooves and flanges varies through several embodiments. Some embodiments alternately use a retention plate. Adhesive may be applied to the axle and the inner surfaces of the axle shell and wedge member to limit axle twist or rotation.
摘要:
A continuous emissions monitoring system is in fluid communication with a flue stack conducting exhaust gas from a combustion source. The continuous emissions monitor system comprises an analyzer for measuring concentrations of an analyte present in the exhaust gas. A probe is in fluid communication with the flue stack to acquire a sample of exhaust gas from the flue stack. The probe is also in fluid communication with and located upstream of the analyzer. The probe tends to remove analyte from the sample. A calibration checking system is in fluid communication with the probe. The calibration checking system includes a source that provides a flow of a known concentration of calibration material to be measured by the analyzer. The calibration material is the same as the analyte. A humidifier is associated with the source to provide moisture to a flow of calibration material. The moisture acts to cleanse removed analyte from the probe and thereby enable an accurate measurement of the concentration of the calibration material. A supply system is operatively connected with the humidifier to provide a desired amount of a liquid to the humidifier.
