100 results about "Narcotic" patented technology

The term narcotic (/nɑːrˈkɒtɪk/, from ancient Greek ναρκῶ narkō, "to make numb") originally referred medically to any psychoactive compound with sleep-inducing properties. In the United States, it has since become associated with opiates and opioids, commonly morphine and heroin, as well as derivatives of many of the compounds found within raw opium latex. The primary three are morphine, codeine, and thebaine (while thebaine itself is only very mildly psychoactive, it is a crucial precursor in the vast majority of semi-synthetic opioids, such as oxycodone).

Chemiluminescent detection of explosives, narcotics, and other chemical substances

ActiveUS6984524B2Rapidly and accurately discriminates among different substancesAccurate and reliable processChemical analysis using combustionMaterial heat developmentCollection systemDesorption
A compact scanning apparatus has an infrared laser adapted to emit light. The light is delivered as a beam by an optical system to illuminate an interrogation area on the surface of an object being scanned. Such illumination has sufficient intensity and duration to cause selective desorption of molecules of the contraband substance, which are present on the surface, without substantially damaging the surface. A collection system collects at least a portion of the desorbed molecules. At least a portion of the collected molecules is thermally decomposed to form NO2 and transferred to a reaction cell containing an aqueous, alkaline, luminol-containing solution. The NO2 reacts with the luminol to produce light by chemiluminescence. A light detector registers the presence of this light as indicative of the detection of the contraband substance, and activates a signaling device to provide an audible or visible alarm. The apparatus rapidly detects the presence of a wide variety of contraband substances in an accurate, reliable manner. It provides for automated screening, with the result that vagaries of human performance are virtually eliminated. False alarms are reduced and detection efficacy is increased. A traceable residue of the detected contraband is left on the article for use in forensic analysis.

Multi-zonal detection of explosives, narcotics, and other chemical substances

A multi-zonal system and method for detecting contraband substances associated with a human subject. Objects containing such substances may be carried by the subject or in a garment worn by the subject, or as vapors entrained by the subject's garments. Alternatively, the substance may be present as small particles or residues present on skin, garment fibers, or the like that may be dislodged from the subject or his immediate effects. The system comprises: (i) an examination station through which the subject passes; (ii) sample generation means to produce a sample for analysis, comprising a plurality of air jets disposed in the examination station to impinge flowing gas onto pre-selected zones on the subject; (iii) collection means operative to acquire and convey the sample, comprising a plurality of collection ports disposed in the examination station to receive gas deflected by the subject from the air jets; (iv) analysis means in communication with the collection means to receive the sample and carry out a chemical analysis to detect the contraband substances; and (v) signal means operably connected to the analysis means for indicating detection of the contraband substances. Preferably the system employs a chemiluminescent detector based on the reaction of luminol with NO2 produced by pyrolysis of explosive or other contraband substance and is capable of high throughput, accurate screening in real time of a large number of subjects, e.g. persons being screened in an airport.

A compact scanning apparatus has an infrared laser adapted to emit light. The light is delivered as a beam by an optical system to illuminate an interrogation area on the surface of an object being scanned to cause selective desorption of molecules of the contraband substance, which are present on the surface, without substantially damaging the surface. A collection system collects at least a portion of the desorbed molecules. At least a portion of the collected molecules is thermally decomposed to form NO2 and transferred to a reaction cell containing an aqueous, alkaline, luminol-containing solution. The NO2 reacts with the luminol to produce light by chemiluminescence. A light detector registers the presence of this light to carry out a rapid screening of the object for the possible presence of the contraband substance. The apparatus further includes a supplemental detector such as a GC / IMS detector that is activated in response to the detection of the chemiluminescent light. The supplemental detector provides confirmation of the detection of contraband substance and activates a signaling device to provide an audible or visible alarm. The rapid pre-screening permits the apparatus to identify suspicious items, while the supplemental detection system can be optimized for more intense, but time-consuming scrutiny of just the suspicious items. Both effective detection and high throughput are thereby achieved in an accurate, reliable manner.

Nerve block injection test device

The invention discloses a nerve block injection test device. The device comprises a nerve block puncture needle, a liquid injection catheter, an injector, an injection pump and a treadle type filling injector; the liquid inlet end of the nerve block puncture needle is connected with the liquid outlet end of the liquid injection catheter; the liquid inlet end of the liquid injection catheter is connected with the liquid outlet end of the injector; the injector is clamped on the injection pump; the treadle type filling injector is connected with the injection pump through signal conveying lines. The device has the advantages that when in implementation, a doctor holds an ultrasonic probe by one hand so that a part which needs anesthetization on a patient body can develop on a computer, the doctor holds the nerve block puncture needle by the other hand to conduct puncture on the corresponding part which needs anesthetization, and then the filling injection of narcotic liquid can be completed by stepping on the corresponding treadle type filling injector, so that the troubles can be omitted that the doctor talks to another doctor and guides another doctor to hold the injector and push the narcotic medicine to a narcotic part, then the injection test work can be completed only by one doctor, and thus the labor can be saved, and the working efficiency can be improved.
