A bioelectrode including a plate, a first electrode disposed on a first side of the plate, and a second electrode disposed on the first side of the plate and separate from the first electrode. The bioelectrode further includes a first guard portion disposed on a second side of the plate, a second guard portion disposed on the second side of the plate and separate from the first guard portion, and a preamplifier configured to output a voltage signal based on a biosignal measured between the first electrode and the second electrode.

Embodiments of the invention provide devices, systems, and methods that precisely identify a minimum of one predetermined spot which is hidden under a skin. The system comprises a locator device and corresponding implanted target device. The port locator device preferably comprises one magnet with north and south magnetic pole, a body and a suspending component. The body may utilize specific geometry which improves accuracy. The implanted target device may include at least one magnet and at least one target or a plurality of targets and at least one magnet. Various configurations can be provided that precisely identify a single spot or a plurality of spots which are hidden under a skin.

A biological data measurement device according to the present invention includes a substrate disposed at a position spaced a predetermined distance from a body surface BS of a living organism as a measuring object via a support member so that an air layer is formed between the substrate and the body surface, in which the substrate is provided with a thermometer including an infrared thermometer for measuring a body surface temperature and a substrate thermometer for measuring a substrate temperature, thereby measuring a deep body temperature with higher accuracy.

A biodegradable pressure sensor for measuring vital physiological pressures and for preventing the buildup of dangerous internal forces in impaired organs. The pressure sensor is constructed by depositing Mg or Mo on both sides of a PLLA film. This layered configuration (Mg/PLLA/Mg) or (Mo/PLLA/Mo) may then be encapsulated by layers of high molecular weight PLA. These materials are biodegradable such that after implantation, the sensor does not require invasive removal surgery that can damage directly interfaced tissues.

A portable electronic device comprises a housing and a chemical sensor arranged inside the housing which chemical sensor is adapted to measure a property of at least one analyte. The device further comprises an opening in the housing for exposing the chemical sensor to the fluid to be analyzed.

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

Provided is a system, method and portable device for monitoring physiological parameters of a person in the field.

An electrochemical sensing system includes a working electrode and a reference electrode, which can at least partially be disposed in a housing. At least a portion of the working electrode includes rhodium metal. An electrical circuit is disposed in the housing and configured to be electronically coupled to the electrodes. The electrical circuit is operative to: (a) bias the working electrode at a voltage of less than about 0.4 V, and (b) measure a current corresponding to the concentration of the target analyte. A communications module is electrically coupled to the electrical circuit and configured to display a concentration of the target analyte, and/or communicate data between the electrical circuit and an external device. The electrodes are movable between a first configuration in which the electrodes are substantially disposed inside the housing, and a second configuration in which at least a portion of the electrodes is disposed outside the housing.

Persons with sleep disordered breathing (SDB) may, or may not, recognize that they have symptoms of SDB, and/or that they may be at-risk of, or suffering certain health problems associated with SDB, including death. The disclosed Energy Conversion Monitor (ECM) sensor, when embodied, for example, in a wearable upper-armband format, has been demonstrated to be more sensitive and responsive than pulse oximetry monitoring of blood oxygen saturation as an indication of hypoxic stress induced by SDB, and is compatible with: (1) inclusion in sleep laboratory polysomnograph (PSG) testing instrumentation, (2) home-based diagnostic testing for SDB, (3) control of home-use airway therapy devices, (4) continuous remote surveillance and refinement of airway therapy, and (5) spot-check and continuous surveillance of sleep quality in the general population. The disclosed ECM also provides new measurements of physiologic stress during and following exercise. When applied during initial care of premature newborn infants, it offers improved therapeutic guidance during their transition from their limited in utero oxygen supply conditions, to the increased oxygen availability from breathing air. When applied during resuscitation of persons suffering from hypoxia and during reperfusion of ischemic tissue, such as during treatment of ischemic stroke, or ischemic heart attack, the ECM sensor can provide objective guidance regarding the safe and effective resupply of oxygen to the hypoxia-adapted tissue to help reduce or prevent microvascular occlusion and cellular injury. As a continuously worn physiologic surveillance monitor, the ECM offers the potential of early detection of sepsis. With the elderly and infirm, it offers a convenient and comfortable means of continuously assessing variations in status while awake and asleep.
