摘要:
The present invention includes systems and methods for monitoring therapeutic drug concentration in blood by detecting markers, such as odors, upon exhalation by a patient after the drug is taken, wherein such markers result either directly from the drug itself or from an additive combined with the drug. In the case of olfactory markers, the invention preferably utilizes electronic sensor technology, such as the commercial devices referred to as “artificial” or “electronic” noses or tongues, to non-invasively monitor drug levels in blood. The invention further includes a reporting system capable of tracking drug concentrations in blood (remote or proximate locations) and providing the necessary alerts with regarding to ineffective or toxic drug dosages in a patient.
摘要:
A method for detecting compounds of interest in bodily fluids, including exhaled breath and blood. The present invention uses biosensors that mimic naturally occurring cellular mechanisms, including RNA oligonucleotide chains or “aptamers,” in combination with signaling agents or nanotechnology to provide an effective and efficient method for diagnosing a condition and/or disease within a patient. The subject invention also provides a method for screening those analytes/biomarkers likely to be present in exhaled breath.
摘要:
Systems and methods for the ex vivo diagnostic analysis of samples of bodily fluids, including exhaled breath and blood. The present invention uses nanostructure-based assemblies in combination with sensor technology to provide an efficient and accurate means for identifying the presence of a target analyte/biomarker in a sample of bodily fluid. In a preferred embodiment, the nanostructure-based assemblies of the present invention include detecting means such as RNA oligonucleotide chains or “aptamers” and releasable surrogate markers such as DMSO.
摘要:
Systems and methods for diagnosing and/or treating conditions, diseases, or disorders. The present invention uses nanoparticle-based assemblies, which comprise a nanoparticle; a surrogate marker; and a means for detecting a specific chemical entity. Such nanoparticle-based assemblies combine nanotechnology and sensor technology to provide an efficient and accurate means for diagnosing a condition, disease, or disorder as well as for focused treatment regimens.
摘要:
Systems and methods for diagnosing and/or treating diseases as well as monitoring disease treatment. For diagnosis, the present invention uses nanoparticle-based assemblies, which comprise a nanoparticle; a surrogate marker; and a means for detecting a specific chemical entity. In certain embodiments, nanoparticle-based assemblies include a payload for simultaneous diagnosis and treatment of disease. In further embodiments, a therapeutic drug and therapeutic drug marker are administered to a patient to monitor disease treatment. Bodily fluid samples are analyzed using sensor technology to detect the presence of surrogate and/or therapeutic drug markers to provide an efficient and accurate means for diagnosing a disease and/or monitoring disease treatment.
摘要:
The present invention includes systems and methods for monitoring endogenous compound concentration in blood by detecting markers, such as odors, upon exhalation by a patient, wherein such markers are the endogenous compound itself or result from the endogenous compound. In the case of olfactory markers, the invention preferably utilizes electronic sensor technology, such as the commercial devices referred to as “artificial” or “electronic” noses or tongues, to non-invasively monitor endogenous compound levels in blood. The invention further includes a reporting system capable of tracking endogenous compound concentrations in blood (remote or proximate locations) and providing the necessary alerts with regard to emergent or harmful conditions in a patient.
摘要:
Systems and methods for the diagnostic analysis of blood samples. The present invention uses sensor technology useful in the analysis of headspace sample from blood to provide an efficient and accurate means for identifying the presence of a volatile marker associated with hematological diseases or conditions. In a preferred embodiment, the sensor technology of the present invention includes detecting means such as RNA oligonucleotide chains or aptamers.
摘要:
Disclosed is an intubation imaging stylet for intubating a patient by use in a tube/imaging stylet combination, said imaging stylet comprising: a malleable stylet having a longitudinal axis and a proximal end and a distal end; a flexible image guide having a longitudinal axis and a proximal end and a distal end, said image guide being connected to said stylet such that a portion of said image guide runs parallel to a portion of said stylet along the longitudinal axis of said stylet and such that the distal end of said image guide is co-extensive with the distal end of said stylet; and at least one flexible illumination fiber having a proximal end and a distal end, said illumination fiber being connected to said stylet such that a portion of said illumination fiber runs parallel to a portion of said stylet along the longitudinal axis of said stylet and such that the distal end of said illumination fiber is co-extensive with the distal end of said stylet; such that in use, said imaging stylet is disposed within a tube for intubating a patient thereby forming an imaging stylet/tube combination which in use is held by gripping the tube in a pen-like fashion. The imaging stylet/tube combination is thus in use held in one hand, freeing the other hand of the user for other tasks if necessary, as well as permitting intubation in the conventional manner. To facilitate this, the center of gravity of the imaging stylet/tube combination is located in essentially the same location along the tube as with a conventional stylet/tube combination.
