A physiological characteristic sensor system includes a physiological characteristic sensor. The physiological characteristic sensor includes a housing having a first housing portion coupled to a second housing portion, and an antenna coupled to the first housing portion. The physiological characteristic sensor system includes a sensor inserter configured to be coupled to the physiological characteristic sensor. The sensor inserter includes a sensor retainer, and the sensor retainer is configured to couple to the second housing portion in a second state to couple the physiological characteristic sensor to the sensor inserter.

A body fat measurement device, disclosed according to the present ion, comprises: at least one electrode unit which supports at least one EIT electrode and is tightly attachable to skin; and a sensor unit which measures electrical impedance tomography information by sensing a signal measured from the electrode unit, wherein, after being connected to the sensor unit and used once, the electrode unit may be separated from the sensor unit and replaced. According to such configuration, the one-time used electrode unit can be replaced from the sensor unit, and thus economic efficiency can be achieved, and convenience of use can be increased.

Apparatus, methods, and systems for detecting alcohol concentrations of an individual, such as an in vivo alcohol concentrations of an individual. The system can include an analyte sensor and a reader. The reader can receive a signal from the analyte sensor. The reader can determine blood alcohol concentration, in part, based on the received signal from the analyte sensor. The reader can also detect an adverse condition of the analyte sensor, and/or output an indication based on the detected adverse condition.

A reusable portion includes a first connector and a light emitter. A disposable portion includes a support, a second connector and a light detector. The support has a translucent portion and adapted to be attached on a body of a subject. The second connector is supported by the support and configured to couple with the first connector. The light detector is supported by the support and configured to output a signal corresponding to an amount of light incident on the light detector. Under a condition that the first connector and the second connector are coupled, the light emitter is disposed so as to face the translucent portion, so that the first connector is enabled to detect the signal via the second connector.

Various embodiments include a vessel clamping pressure device that is configured to receive suture threads extending from the closure of a vascular vessel of a patient, and maintaining tension on suture threads between the patient and the vessel clamping pressure device to apply pressure to the patient so as to apply a clamping pressure to the vascular vessel to facilitate clotting.

A sensor cartridge according to embodiments of the disclosure is capable of being used with a non-invasive physiological sensor. Certain embodiments of the sensor cartridge protect the sensor from damage, such as damage due to repeated use, reduce the need for sensor sanitization, or both. Further, embodiments of the sensor cartridge are positionable on the user before insertion in the sensor and allow for improved alignment of the treatment site with the sensor. In addition, the sensor cartridge of certain embodiments of the disclosure can be configured to allow a single sensor to comfortably accommodate treatment sites of various sizes such as for both adult and pediatric applications.

A device for collecting aerosol particles in an exhaled air flow. The particles may be aerosol particles such as biomarkers or particles related to drugs or other substances formed or found in the alveoli of the lungs. The device comprises an elongate housing with an inner wall and at least four first type partition walls extending substantially perpendicularly from opposite sides of the inner wall to partly cover the cross-section of the housing. The first type partition walls create a labyrinth shaped flow path to divert air flowing from the inlet towards the outlet of the housing in a direction towards opposite inner walls of the housing so that the particles separate from the air flow and attach on the device. The distance between two opposite first type partition walls is smaller than the transverse width of the housing and increases in the flow direction.

A respiration monitoring system has deformation transducers on a flexible substrate arranged to adhere to a patient's torso. A processor receives signals in channels from the transducers and processes them to eliminate, reduce or compensate for noise arising from patient motion artefacts, to provide an output representative of respiration. The transducers have a size and a mutual location on the substrate so that a first transducer can overlie at least part of the 10.sup.th rib and a second transducer can overlie at least part of the 11.sup.th rib or the abdomen, and the processor processes data from the first transducer as being primarily representative of rib distending respiration and from the second transducer as being primarily representative of either diaphragm respiration or patient motion artefacts.

A barrier or cover used for protecting instrumentation in a medical and/or biological setting, and more specifically, a multi-piece apparatus having a multi-use component and a single use component configured to be matted to the multi-use component, wherein the single use component is configured for matting to the multi-use component and shielding the multi-use component.
