摘要： A highly selective, sensitive, fast detection system and method are disclosed for detecting vapors of specific compounds in air. Vapors emanating from compounds such as explosives, or stripped from surfaces using heat and suction from a hand-held sample gun, are collected on surfaces coated with gas chromatograph (GC) material which trap explosives vapors but repel nitric oxide, then are desorbed and concentrated in one or more cold spot concentrators. A high speed gas chromatograph (GC) separates the vapors, after which specific vapors are decomposed in two pyrolyzers arranged in parallel and the resulting nitric oxide is detected. A low temperature pyrolyzer with silver produces NO from nitramines or nitrite esters; a high temperature pyrolyzer decomposes all explosives vapors to permit detection of the remaining explosives. Also disclosed is a series arrangement of pyrolyzers and gas chromatographs and an NO detector to time-shift detection of certain vapors and facilitate very fast GC analyses. The use of hydrogen as a carrier gas, plus unique collectors and concentrators, high speed heaters, NO detectors, and very fast, temperature-programmable GC's enhance selectivity, sensitivity and speed of detection.

摘要： Disclosed is an improved peritoneal access system for providing repeated, long term access through the peritoneum, as for patients undergoing peritoneal dialysis. The system includes a catheter tube extending through an implantable percutaneous access device (PAD) formed of a cylindrical neck and a buttonlike annular skirt. A portion of the catheter tube external to the PAD has a bellows integrally formed therein permitting the tube to be bent and moved without restricting fluid flow or stressing the PAD. The internal portion of the catheter tube has a sharp right angle below the PAD to tunnel the tube in a subcutaneous plane to the peritoneal penetration site and a position-adjustable collar for anchoring/sealing the cathether tube near the upper surface of the peritoneum.

摘要： Disclosed is a percutaneous access device (PAD) with a connector lock which facilitates replacement and removal of tubes transmitting materials to or from the body of a patient without the need for surgery and with minimal interference with an implanted PAD. The lock may include a screw ring and elastomeric seal attachable to the neck of the device through which a tube extends, and the neck has recesses in its outer surface to permit it to be tightly restrained during tightening or loosening of the lock. A flat skirt or flange provides subdermal anchoring of the buttonlike percutaneous access device, and a two-stage porous bed covering portions of the neck and skirt promotes formation of a tight dermal/biomaterial barrier near the junction of the two stages of the porous bed.

摘要： Disclosed is a method of rapidly checking surfaces for the presence of traces of specific compounds such as certain explosives and drugs. A hand-covering such as a cotton glove is used to wipe surfaces to pick up particles of the specific compound which may indicate the presence of larger amounts or previous contact of a surface by a person who has handled the compound. The particles are transferred--unheated--to collection surfaces of a hand-held sample probe by vacuuming of the gloved hand by the battery-operated probe. Heat is then supplied by a source external to the probe to vaporize the particles, and the vapors are analyzed by a suitable technique such as high speed gas chromatography. The method permits checking of surfaces for explosives at processing rates of up to several samples per minute.

摘要： Disclosed is a portable, hand-held vapor sampling probe for collecting vapors of compounds such as cocaine, heroin, and explosives prior to their desorption and analysis in a vapor detector. Rechargable batteries power a lamp in the front face of the probe for heating target portions of a sampling surface, a puffer assembly for directing air jets at the target, and a motor for drawing air samples through a collector coil on whose surfaces vapors are trapped. A flexible U-shaped shroud on the front face partially encloses the lamp and collector and helps to regulate air flow over the target and to protect the probe from damage. Upon contact with a surface, the shroud may activate a switch which, together with a second switch on the probe handle and a lamp pyrometer, regulates heating of the target.
