Abstract:
A vaginal fluid monitoring device includes an absorbent layer, wherein the absorbent layer is configured to be in proximity to flow of vaginal fluid; an electrochemical detection system configured to obtain data regarding at least one analyte in a vaginal fluid, said electrochemical detection system in fluid communication with the absorbent layer; and wherein the vaginal fluid monitoring device is configured to be coupled with a feminine hygiene product.
Abstract:
A device comprises a first cavity (300) and a second cavity (400), wherein the first cavity (300) is positioned in the second cavity (400), and may seal and compress the second cavity (400) so that the liquid in the second cavity (400) is discharged out quantitatively. The device may fully mix a buffer solution with a sample and achieves the function of integration of collection and test. Further, a collecting device also may achieve the quota-sampling function.
Abstract:
The devices and methods taught in this disclosure are directed to facilitate the observation, collection, transportation, storage, and preservation of specimens possibly containing DNA, said specimens potentially constituting evidence of sexual assault. The devices and methods described further allow for a means of minimizing the possibility of specimen contamination, dilution, or degradation during the collection and storage processes. The disclosed devices may contain electrical components that provide for the generation and recordation of information (specifically, times, dates, and locations) related to circumstances surrounding the collection of such specimens. This information may serve as evidence corroborating the circumstance of specimen collection, it may help to maintain a known and identifiable Chain of Custody (CoC), and it may additionally be used for unique device identification (UDI), inventory control, and current procedural terminology (CPT) coding purposes.
Abstract:
Disposable test units to assist medical personnel are described. In some embodiments, a test unit includes: a solid support; a cavity in the solid support; a reaction chamber internal to the solid support, including a plurality of biochemical reagents; a first internal channel in the solid support, connected at a first end to the cavity, connected at a second end to the reaction chamber; at least one pathogen detection region internal to the solid support; a second internal channel in the solid support, connected at a first end to the reaction chamber, connected at a second end to the at least one pathogen detection region; a temperature detector; and a persistent visible temperature indicator attached to the temperature detector.
Abstract:
A lancet enclosed in a sterility sheet forms a lancet packet to maintain the sterility of the lancet and prevent the lancet from unintentionally piercing the sterility sheet prior to lancet actuation. In one form, the lancet is immobilized by hot tack welding a portion of the sterility sheet to the lancet. Alternatively, portions of the sterility sheet are hot tack welded together through an opening in the lancet to limit movement of the lancet.

Abstract:
A compact module capable of performing one or more laboratory tests in nano-scale and/or micro-scale structures is provided. Such compact module may be made on silicon substrates by using manufacturing techniques typically applied to electronic and/or semiconductor manufacturing/fabrication. One aspect of the invention applies curling film technology to create and link three-dimensional elements that allow miniaturization of laboratory components and functions.
Abstract:
An oral fluid collection device includes a housing and a mouthpiece which communicates an oral fluid sample into a sample distributor within the housing. Sample collection vessels are detachably mounted on the housing, and passages extend through the housing. Each passage communicates the sample with an individual vessel, thereby dividing the sample between the vessels.
Abstract:
The invention relates to a transdermal analyte monitoring system comprising a medium adapted to interface with a biological membrane and to receive an analyte from the biological membrane and an electrode assembly comprising a plurality of electrodes, wherein the medium is adapted to react continuously with the analyte, an electrical signal is detected by the electrode assembly, and the electrical signal correlates to an analyte value. The analyte value may be the flux of the analyte through the biological membrane or the concentration of the analyte in a body fluid of a subject. The medium may comprise a vinyl acetate based hydrogel, an agarose based hydrogel, or a polyethylene glycol diacrylate (PEG-DA) based hydrogel, for example. The surface region of the electrode may comprise pure platinum. The system may include an interference filter located between the biological membrane and the electrode assembly for reducing interference in the system. The system may comprise a processor programmed to implement an error correction method that corrects for sensor drift.
