摘要： This invention is an optical measuring device having multiple optical paths between one or more light emitters, one or more light detectors, and/or providing at least two sets of wavelength of light along at least one path, with a final measurement being produced as a combination of measurements of the sets of wavelengths of light taken along one or more of the optical paths. Features that contribute to increased safety, and ease of use include a receiving cavity in a proximal end of an insertion rod (7) that holds a free end of a circuit connector (9) to keep it from becoming entangled or snagged; a mechanism to keep the sensor (11) within an introducer tube (5) during storage and insertion, and to expose a portion of the sensor when the sensor is applied to the unborn baby; a tab (13) on the insertion rod to prevent the circuit connector from becoming tangled or snagged within the introducer tube; a rotating feature whereby if a torque applied on the sensor exceeds a first predetermined amount the sensor rotates; a disengaging feature whereby the sensor detaches from insertion rod if a pull off force exceeds a second predetermined amount; a circuit connector (9) that includes at least one of the following features: a stiffening member provided at the proximal end to minimize bending, a shielding layer, and at least one slit to increase the flexibility of the circuit connector; and an interface that includes an identification element that is detected by an external circuit only if the circuit connector is connected to the interface. The present invention also pertains to a method of manufacturing a needle that is used in the sensor.

摘要： The invention concerns a process for validating devices used for carrying out photometry of living tissues. The process involves the following steps: a specified concentration of a substance which is to be detected in a bodily fluid is set in vitro; the bodily fluid whose concentration has been set is transferred to at least one measurement cell; light is passed through the bodily fluid; a light intensity is measured in at least one spectral window to determine at least one suitable parameter in the bodily fluid contained in the measurement cell, using at least one transmitter and one receiver (the effective absorption length through the bodily fluid is actively and dynamically altered in a defined way without using the bodily fluid to transmit forces; the bodily fluid occupies the optical space between the transmitter and receiver); and at least one relationship is ascertained between the concentration, on the one hand, and the suitable parameter, on the other. This process gives particularly accurate results in the calibration of pulse oximeters. The invention also concerns devices used for implementing the process and associated calibrated pulse oximeters.
