A control circuit for a sensor provided in a long member which can be inserted into a lumen to measure the flow velocity of a fluid in the lumen and a measurement device. The control circuit includes a drive circuit supplying a drive current to the sensor. A leakage current detection circuit detects a leakage current and performs an output corresponding to the detected leakage current. The leakage current detection circuit outputs a detection signal in response to detection of a leakage current exceeding a threshold value. A stop circuit stopping supply of the drive current to the sensor by the detection signal is further provided.

An apparatus (10) is for use with an inflatable cuff (14) for performing oscillometric blood pressure measurements, and the apparatus configured for detecting slippage of a cuff fastening (15). The apparatus includes a control unit (12) in combination with an acoustic sensor (20). The acoustic sensor is arranged so as to be sensitive in use to sounds emanating from the cuff during inflation of the cuff for performing a blood pressure measurement. A control unit acquires from the cuff a pressure signal indicative of pressure in the cuff, the pressure signal for oscillometrically deriving a blood pressure measurement. The control unit is further configured to receive a sensor input from the acoustic sensor and process it to detect sound signatures in the signal corresponding to a slippage of a fastening arrangement of the cuff, to thereby detect occurrence of cuff fastening slippage events. The control unit is then configured to trigger a response action responsive to detecting any slippage event, which could be processing the pressure signal to detect and compensate any artifacts in the signal caused by the slippage event, or could be for labelling the acquired measurement to alert a user that it could be compromised.

Aspects of the present disclosure include a sensor configured to store in memory indications of sensor use information and formulas or indications of formulas for determining the useful life of a sensor from the indications of sensor use information. A monitor connected to the sensor monitors sensor use and stores indications of the use on sensor memory. The monitor and/or sensor compute the useful life of the sensor from the indications of use and the formulas. When the useful life of the sensor is reached, an indication is given to replace the sensor.

The invention relates to a method and apparatus for diagnosis of conductor anomalies, such as insulation failures, in an implantable medical device, such as an implantable cardioverter defibrillator (ICD), a pacemaker, or a neurostimulator. Insulation failures are detected and localized by identifying changes in electrical fields via surface (skin) potentials. Small variations in potential are detected along the course of the electrode near the site of insulation failure.

Methods and devices and systems including a communication module operatively coupled to a data collection module for communicating the stored analyte related data after the analyte related data is stored in the data collection module over a predetermined time period, and a user interface unit configured to communicate with the communication module to receive from the communication module the stored analyte related data in the data collection module over the predetermined time period, and to output information associated with the monitored analyte level, where the user interface unit is configured to operate in a prospective analysis mode including substantially real time output of information associated with the monitored analyte level, or a retrospective analysis mode including limited output of information during the predetermined time period wherein no information related to the monitored analyte level is output during the predetermined time period, are provided.
