Abstract: The invention relates to an apparatus for measuring blood oxygen saturation, comprising a housing (1), a sensor (2), a connecting cable (3) and a plug (4), wherein the housing (1) has a cavity (5) for accepting a patient's tissue which is supplied with blood; the sensor (2) which is arranged on the housing and has at least one light source (21) for the emission of light which passes through the tissue which is supplied with blood and a detector (22) for receiving the light passing through the tissue which is supplied with blood; and the apparatus can be connected to an evaluation unit via the plug (4).

Abstract: The invention relates to a device and a method for measuring blood, tissue, or skin parameters, in particular the oxygen saturation in blood, by attaching one or more sensors to body parts such as fingers, earlobes, toes, hand, or foot. The invention relates further to a method for the preparation of said device.

Abstract: An apparatus for measuring the blood oxygen level of a patient is disclosed. In one embodiment, the apparatus includes a housing having an interior surface of non-reflective material substantially surrounding an interior. A cooperating light source and detector are operatively positioned proximate the interior surface so as to emit and receive light projected within the interior of the housing. A material more conducive to light transmission, reflectance, or a combination thereof—as compared to the interior surface material—is positioned proximate the light source and/or detector.

Abstract: The invention relates to a device for collecting samples of fluids, in particular of body fluids such as saliva, said device comprising an absorbent pad and two housing parts which are connected to the latter in a movable manner and can enclose the absorbent pad. The device permits easy and safe handling when taking a sample and when transferring the sample for testing for an analyte in the sample. The device can also be handled hygienically and safely by persons not trained in taking samples.

Abstract: The invention relates to an inexpensive method in which the partial pressure of a gas component in the air exhaled by a patient is determined per breath.

Abstract: Device for measuring the alcohol vapor concentration in a sample, wherein the device comprises an electrochemical sensor capable of monitoring alcohol through a diffusion current, means for determining the limiting diffusion current and means for generating an alcohol vapor concentration signal from the determined limiting diffusion current.
