Embodiment Construction

[0195] Figure 1a A side view of the device 1 according to the invention is shown. The device 1 has one or more lighting devices 20 (see Figure 4 ). Here, the light emitting device 20 illuminates the measurement area 3 to be detected, typically skin and tissue areas, as a substantially two-dimensional area, which has a relatively narrow length in the Y direction. In different embodiments, the linear measurement area 3 is illuminated by the illumination device in a reflection or transmission manner, and the linear measurement area 3 emits analysis light 4 according to its transmission or reflection behavior. The analysis light 4 is coupled to the spectrometer unit 22 through the deflecting mirror 5. In order to determine the oxygen saturation in the blood and other blood data, in this case the analysis light 4 is in the visible light (VIS) and near infrared light (NIR) regions, for example, the wavelength range is between 500nm and 850nm, and has According to the spectral dis...

Abstract

The invention relates to a device for detecting and monitoring ingredients or properties of a measurement medium, for example physiological blood values, wherein said device contains a light source (20) for generating broad-spectrum measurement light (2) and for acting on a measurement area (3), and means (9) for fanning out the analysis light (4) reflected by the measurement area (3). The device also has a sensor array (11) for picking up the fanned light. The sensor array (11), the light source (20) and the means for dispersing the analysis light (4) are arranged as a compact unit in a housing.

Description

Technical field [0001] The invention relates to a device and a method for determining and monitoring the content or characteristics of a measuring medium, in particular for determining and monitoring physiological blood values, which have the characteristics of the preamble of the independent claim. Currently, there are monitoring and measurement of the content or characteristics of measurement media in a variety of medical and non-medical applications. For example, the patient's blood content (for example, blood sugar or oxygen saturation) or the content of process fluids (liquid or gas) for non-medical applications (for example, process monitoring) should be measured and continuously monitored in real time. Background technique [0002] For example, the pulse oximeter method is a method to measure the pulse rate (PR) of arterial blood and the percentage of oxygen saturation (%SpO 2 )Methods. At present, this is an established method and used in many medical fields, such as in ...
