摘要:
Provided according to embodiments of the invention are systems for monitoring a physiological state of an individual that include a PPG sensor, which optionally includes an auxiliary physiological sensor integrated with or connected thereto; a first signal processing device in electronic communication with the PPG sensor, whereby the PPG sensor transmits PPG signals to the first signal processing device; and a second signal processing device that detects at least a portion of the signals transmitted by the PPG sensor to the first signal processing device, at least a portion of signals transmitted by the auxiliary physiological sensor, or both. Related methods are also provided herein.
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:
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.

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.

Disclosed herein is a novel surgical instrument, and method of using same, designed for performing tracheotomy. According to specific embodiments, the subject surgical instrument comprises a novel foot plate that is anatomically curved to follow the contours of the inner wall of the trachea.
摘要:
Disclosed herein is a novel tube-in-tube endotracheal tube apparatus that allows for replacement or cleaning of an inner (first) tube without having to re-intubate the patient. The novel endotracheal tube apparatus enables the application of continuous suction or intermittent suction. The endotracheal device also serves to decrease the incidence of ventilator-associated pneumonia (VAP).
摘要:
The present invention includes a method and apparatus for detecting humans or human remains by analyzing air, fluid, or soil using electronic sensor technology, including surface acoustic-wave gas sensor technology. The method determines the presence and concentration of the target compound (or a class of compounds) associated with humans or human decomposition. Diagnostic software is used to identify target compounds where a stored library of signatures is compared to the signature obtained from the system. Signal processing and neural networks are preferably utilized in the analysis.
摘要:
Disclosed herein are methods, devices and systems for accurately monitoring various pressures of a patient. The invention embodiments herein allow for taking into account pressure changes attributed to changes in elevation and tilt attitudes of the patient. Further disclosed herein is a unique and new pressure correction unit that comprises a tilt sensor affixed thereto or integrated therein.
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:
The subject invention pertains to a system for imaging the human airway having highly advantageous optical, mechanical, ergonomical and physical characteristics. In a specific embodiment, the human airway can be imaged during the intubation procedure. The subject imaging scopes can incorporate a malleable stylet which retains its shape when bent, in order to facilitate intubation of a patient. In a preferred embodiment, a solid metal stylet, for example, a conventional endotracheal tube stylet, can be utilized. In a specific embodiment the subject intubation scope allows for a user to utilize conventional techniques for the insertion of an endotracheal tube, reducing the training needed for use of the subject intubation scope. Preferably, the subject imaging scopes also incorporate at least one illumination fiber to convey light to the distal tip of the subject imaging scopes, for illumination of the objects to be imaged.
