    Abstract: When performing the method a sensor (1) is used with a coil (15) integrated in a coil circuit. In the coil circuit a magnetic field is generated so that mutual induction can develop between the coil circuit and the surroundings of the sensor (1). The magnetic field in the coil circuit is detected intermittently, and a developed mutual induction is detected as a change of the magnetic field. The position of the sensor is monitored on the basis of said intermittent detection of the magnetic field in the coil circuit. The change of the magnetic field in the coil circuit can be detected in several ways. If the magnetic field is varying, the change may for example be detected as a change of the peak value of the voltage across or the current intensity through the coil circuit or be detected as a phase shift of one of these parameters. The method is used especially to ensure that calibration of the sensor (1) is performed only when the sensor (1) is located in a related calibration chamber (24). The detectable mutual induction is developed between the coil circuit with the coil (15) and an aluminum cup (22) constituting the calibration chamber (24).

    Abstract: A measurement probe (1) contains a self-adjusting oscillating circuit with a measurement coil (5) and a retroactive coil (6). The measurement coil forms part of an LC oscillating circuit. The oscillator is tuned so that the oscillation periodically ceases and is excited again only after a certain delay time. The measurement parameter is the (low) frequency of the oscillation periods. When the probe (1) approaches the metallic part, the oscillating circuit is damped. The resultant frequency shift of the oscillation periods is measured by an evaluation and indicated optically and/or acoustically or used for control purposes. A metallic object can thus be loacted rapidly and reliably by a probe of small dimensions.

    Abstract: The system is designed to locate or detect if in a surgical operation compresses or surgical instruments have been forgotten inside the patient. The system comprises the incorporation of a receiver in the compresses, said receiver being formed of a coil and a capacitor for generating an electric current induced when the receiver is subjected to the electromagnetic field created by an external emitter provided with means for setting in operation the receiver and with a coil connected to a capacitor, so that the self-induced current created in the receiver when stopping the electromagnetic field is detected by the emitter itself, thus generating in the emitter a current capable of activating a supply circuit for a light and/or acoustic signalling device which forms part of the emitter itself, to indicate, in the case of activation, the existence of the surgical compress inside the patient who has been operated.

    Abstract: The present invention relates to a method and apparatus used to place a catheter (100) having a distal end (106) and a proximal end (102, 104) where the proximal end cannot be trimmed within a patient. The method and apparatus utilize a device operative in locating the tip of a catheter, which includes a detector assembly (200) having a detector (220) and a locator (240). The detector (220) of the detector assembly (200) is locked into position remote from the distal end (106) of the catheter (100) prior to inserting the catheter in the patient. The distal end of the catheter (100) is trimmed, as to define a trimmed distal end, the detector (220) is then unlocked and placed proximate the trimmed end. In the preferred embodiment the detector (220) is locked into place proximate the trimmed distal end and the catheter (100) is placed within the patient.
