摘要： An optical measuring device having multiple optical paths between one or more light emitters and 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 providing (1) a receiving cavity in a proximal end of an insertion rod that holds a free end of a circuit connector to keep it from becoming tangled or snagged, (2) a mechanism to keep the sensor within an introducer tube during storage and insertion and to expose a portion of the sensor only when the sensor is applied to the unborn baby, (3) a tab on the insertion rod to prevent the circuit connector from becoming tangled or snagged within the introducer tube, (4) a rotating feature whereby if a torque applied on the sensor exceeds a first predetermined amount, the sensor rotates, and a disengaging feature whereby the sensor detaches from insertion rod if a pull-off force exceeds a second predetermined amount, the rotating and disengaging features being independent of one another, (5) a circuit connector that includes at least one of the following features: (a) a stiffening member provided at the proximal end to minimize bending, (b) a shielding layer, and (c) at least one slit to increase the flexibility of the circuit connector, and (6) 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 an invasive sensor, and preferably for fetal monitoring, that provides features not heretofore available in conventional sensors.

摘要： The invention concerns a process for validation of devices for photometry of living tissue, which encompasses the following steps:in vitro adjusting of a particular concentration of a substance to be detected in a bodily fluid;transporting the bodily fluid which has been adjusted to a pre-determined concentration to at least one measuring cell;transillumination of the bodily fluid; andsensing of the light intensity of at least one spectral window for determination of at least one suitable parameter in the bodily fluid, which is contained in the measuring cell, by means of at least one emitter and at least one receiver;thereby characterized,that one actively and in a defined manner dynamically changes the effective absorption length through the bodily fluid, without using the bodily fluid for transmission of the forces, wherein the bodily fluid is found in the optical space between the emitter and the receiver; andestablishment of at least one relationship between the concentration on the one hand and the suitable parameter on the other hand. This process provides very precise results in the calibration of pulse oximeters. The invention concerns also the device for carrying out the process as well as appropriately calibrated pulse oximeters.
