Abstract: A blood coagulation system analysis device capable of analyzing a blood coagulation system with high accuracy, and a method and a program for analysis of a blood coagulation system are proposed. The blood coagulation system is observed as a temporal change in permittivity before the viscoelasticity manifestation timing (timing at which blood starts to clot from the viewpoint of viscoelasticity (in greater detail, timing at which active polymerization of fibrin monomers starts)). A permittivity of blood which is positioned between a pair of electrodes is measured at predetermined time intervals after the anticoagulant effect acting on the blood is ended, and from the measurement result, a degree of the action of the blood coagulation system is analyzed.

Abstract: Systems and methods described herein use near field communications to locate a radiating transponder, such as a pill swallowed by a patient. The system can be triggered to turn on and transmit a waveform to a set of antennas attached to, coupled with, or near the patient. The magnetic field emitted by the transponder can be measured by the receiving antennas, for example, using principles of mutual inductance. The differential phase and/or time shifts between the antennas can contain sufficient information to find the location of the transponder and optionally its orientation relative to body coordinates. The system can display the location and/or orientation of the transponder. Further, the pill can include a reservoir to deliver a payload at a particular site of the patient's body based at least in part on the determined location.

Abstract: A blood pressure and cardiac monitoring system includes a sensing assembly, a processor, a memory, a communication interface, and any suitable computer implemented modules communicatively coupled to each other via a bus. The sensing assembly comprises of a first sensor (single or multi-axes) located at a first axis of a target generating a first time-dependent motion waveform representative of one or more contractile properties of the target's heart and a second sensor (single or multi-axes) located at a second axis of the target generating a second time dependent motion waveform representative of the target's blood flow. The first and second sensor can be integrated in a multi-axes sensor which sense both the axes. The processor is configured to receive the first time dependent motion waveform and the second time dependent motion waveform, and to determine a first time difference between a vital sign present in the first time dependent motion waveform and the second time dependent motion waveform.

Abstract: Devices associated with on-body analyte sensor units are disclosed. These devices include any of packaging and/or loading systems, applicators and elements of the on-body sensor units themselves. Also, various approaches to connecting electrochemical analyte sensors to and/or within associated on-body analyte sensor units are disclosed. The connector approaches variously involve the use of unique sensor and ancillary element arrangements to facilitate assembly of separate electronics assemblies and sensor elements that are kept apart until the end user brings them together.

Abstract: A sensor can be manufactured by printing a working electrode onto a substrate using aerosol jet printing. Sensing chemistry (e.g., enzyme-based ink that including detection chemistry) also can be printed onto the working electrode using aerosol jet printing. A reference electrode also can be printed on the substrate at a position spaced along the substrate from the working electrode. In certain examples, the substrate can be positioned within a lumen of a skin piercing member of a sensor module.

Abstract: On-body units are provided and include a transcutaneous analyte sensor, electronic circuitry electrically coupled to the sensor, and an on-body housing having electrical contacts disposed thereon. The on-body housing comprises a substantially flat surface and a curved and convex surface opposite the substantially flat surface. Systems and methods including the on-body units are also provided. Methods for performing continuity measurements using on-body units are also provided. The methods include positioning an on-body unit (OBU) on a skin of a subject, contacting a continuity test instrument to the OBU; and performing a continuity measurement with the continuity test instrument. An AC signal may be provided across two electrical contacts, or a DC signal may be provided across two electrical contacts in opposite directions for the same amount of time. The measurement may be performed with one electrical contact, or with isolated electrical contacts.
Abstract: Example biosensor devices having wake-up batteries and associated methods are disclosed. One example device includes a biosensor that has a first electrode for insertion into a subcutaneous layer beneath a patient's skin, and a second electrode coupled to the first electrode for insertion into the subcutaneous layer, and a first battery to apply a voltage across the first and second electrodes, the first battery at least partially electrically decoupled from the electrodes. The device also includes a second battery having an anode material coupled to the first electrode for insertion into the subcutaneous layer, and a portion of the second electrode. The second battery is activatable upon immersion in an electrolytic fluid. The device also includes a wake-up circuit to receive a signal from the second battery and, in response, to electrically couple the first battery to the first and second electrodes to activate the biosensor.
Abstract: The invention aims at downsizing a sensor node incorporating a biosensor to detect biological information and at improving the accuracy of detection made by the biosensor and ensures a quality of communication performed by the sensor node. In the sensor node, a sensor section with a pulse wave sensor formed therein and a main body section with a data processing unit and a wireless communication unit formed therein are separated. The sensor section includes an A/D converter unit that converts an analog signal corresponding to biological information detected by the pulse wave sensor to a digital signal. Digital signal transmission is performed from the A/D converter unit to the data processing unit. Moreover, in the sensor node, there is no conductive member that planarly overlaps with an antenna.
Abstract: Membrane systems incorporating silicone polymers are described for use in implantable analyte sensors. Some layers of the membrane system may comprise a blend of a silicone polymer with a hydrophilic polymer, for example, a triblock poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) polymer. Such polymeric blends provide for both high oxygen solubility and aqueous analyte solubility.
Abstract: Disclosed herein is a new and improved non-invasive bed sensing system for detecting and monitoring physiological movements such as heartbeat and respiration. The system may employ a hydraulic fluid to transduce the physiological pressures to an integrated pressure sensor and a new and improved signal processing method to identify individual cardiac pulses from the electronic signals generated by the hydraulic transducer. The system provides increased sensitivity capable of capturing quantitative pulse and respiration rates with subtle changes, ability to distinguish between instances of low pulse rate and shallow breathing, and improved comfort over existing systems.
