摘要:
The invention relates to a combined two-compartment device for diagnosing body liquids, which comprises: (a) an upper compartment for collecting and storing the body liquid; (b) a lower diagnostic compartment for diagnosing the body liquid at a diagnostic stage, said diagnostic compartment comprises a diagnostic strip; (c) an opening at the bottom wall between said upper compartment and said lower compartment, wherein said opening is kept blocked by a suitable valve until just before said diagnostic stage; and (d) a mechanism for releasing said blockage of said opening, thereby to allow flow of the body liquid to said lower compartment, and thereby to come into contact with said diagnostic strip and to affect the diagnostic strip accordingly.

Embodiments of the disclosed invention provide devices and methods for buffering fluid samples to enable accurate concentration measurements of analytes by salinity-sensitive or pH-sensitive sensors. The buffering capabilities of the device include the ability to control the salinity and pH of a fluid sample, specifically, through the management of solutes such as salts, H+, other ions, and other solutes, that are found in sweat, biofluids, or other fluids. The purpose of such control is to enhance particular fluid sensing device applications by improving detectability of the targeted analyte, or improving performance of analyte sensors. Some embodiments also include components to enable sample concentration to enhance the measurement of low-concentration solutes found in the fluid.

A sweat sensor device for sensing at least one analyte includes a plurality of sensors for sensing said at least one analyte and for producing data. Data from a subset of said plurality of sensors is prioritized over data from sensors of said plurality of sensors which are outside said subset. A method of sweat sensing and prioritizing data in a device including a plurality of sensors includes determining a subset of sensors from said plurality of sensors by at least one sensing mechanism that measures a presence of or a property of sweat. The method further includes prioritizing data from a subset of the plurality of sensors over data from sensors of said plurality of sensors that are outside said subset.

The technology disclosed herein may be used to detect drugs with potential for abuse within a human subject. This technology may be particularly useful to discriminate between drugs of abuse, corresponding psychoactive compounds, and corresponding metabolite byproducts, which are often closely related and possess similar chemical structures. The disclosed technology uses infrared light reflectance characteristics particular to one or more chemical compounds to be detected for identification of those compounds within the human subject.

The invention relates to a skin scraper in the form of a blade, characterized in that said blade has two long sides a and b and two narrower sides c and d, the sides a and b having the same shape.
摘要:
Die Erfindung bezieht sich auf eine Vorrichtung (1) zur Überwachung eines Zustands eines Lebewesens (100). Dabei weist die Vorrichtung (1) einen ersten Sensor (2), einen zweiten Sensor (3) und eine Auswertevorrichtung (4) auf. Der erste Sensor (2) erzeugt basierend auf einem Anteil von Ammoniak im Schweiß des Lebewesens (100) nichtinvasiv einen Messwert. Der zweite Sensor (3) erzeugt einen Messwert bezüglich der Atmung oder der Herztätigkeit des Lebewesens (100). Die Auswertevorrichtung (4) erzeugt basierend auf den Messwerten des ersten und zweiten Sensors (2, 3) ein skalares Maß für eine Belastung des Lebewesens (100). Weiterhin bezieht sich die Erfindung auf ein entsprechendes Verfahren.
摘要:
Methods for obtaining a sample from a subject include providing a sample collection room within a retail store; and obtaining a sample from the subject. Sample collection rooms may include one or more of a warming table; a warming plate; a fingertip warmer; an air-warmer; a reclining chair; a calming feature; and adjustable lighting. Samples may be analyzed at the retail location or sent to elsewhere for analysis. Sample collection rooms may house a sample analysis device or system. Samples may be small, e.g., a finger-stick, and may be analyzed in a short period of time, e.g., in less than five hours, or less than four hours.
摘要:
The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood from subjects. In one aspect, the present invention is directed to devices and methods for receiving or extracting blood from a subject, e.g., from the skin and/or from beneath the skin, using devices containing a substance transfer component (for example, one or more needles or microneedles) and a reduced pressure or vacuum chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In some embodiments, the device may contain a "snap dome" or other deformable structure, which may be used, at least in part, to urge or move needles or other suitable substance transfer components into the skin of a subject. In some cases, for example, the device may contain a flexible concave member and a needle mechanically coupled to the flexible concave member such that the needle may be urged or moved into the skin using the flexible concave member. Other aspects of the present invention are directed at other devices for receiving blood (or other bodily fluids, e.g., interstitial fluid), kits involving such devices, methods of making such devices, methods of using such devices, and the like.
