Patent number: 11751805Abstract: A detection system (100) detects at least ethanol in human sweat. The detection system (100) includes at least one sensor (105) that is an electrochemical gas sensor. The at least one sensor (105) is configured at least for the detection of ethanol. The detection system (100) further includes a measuring chamber (107), in which substances excreted by the user via the user's skin can be fed via a waterproof, gas-permeable diffusion membrane to the at least one sensor (105). The detection system (100) further includes at least one seal (127), which is configured to be brought into direct contact with the skin of a user and to protect at least the measuring chamber (107) from environmental effects.Type: GrantFiled: June 19, 2020Date of Patent: September 12, 2023Assignee: Dräger Safety AG & Co.

Patent number: 11117126Abstract: A reaction carrier (14), a measuring device (12) and a measuring method for measuring a concentration of gaseous/aerosol components of a gas mixture uses reaction material (48) which reacts in an optically detectable manner with at least one component to be measured or with a reaction product of the component to be measured. The reaction carrier includes a flow channel (42) with sections (43) and extends between connecting elements (44). A gas treatment element (47), in each of the sections, changes chemical or physical properties of the gas mixture flowing therethrough or reacts, depending on the chemical or physical properties. The sections are separated from each other in a gas-tight manner by a separating element (49). A coupling element (45) opens the separating element and establishes a connection between the sections when the coupling element is activated. The measuring device includes an activation element (25) to activate the coupling element.Type: GrantFiled: April 15, 2014Date of Patent: September 14, 2021Assignee: Dräger Safety AG & Co.

Patent number: 8262999Abstract: Tempering of sample (58) in test strip (37) is carried out by temperature regulating unit (40) and heating/cooling unit (92). The sample is fed to the test strip by a developer fluid (57) and a metering unit (55). The result of the detection reaction becomes visible by a change in color (36), which is detected optically and analyzed. The data of a control chart (52) with the measured values of first and second temperature sensors (41, 42) are used to set the control parameters for tempering. Code (86) on the test sample holder (35) is read in a sequence of steps. Parameters for phases of the measurement are determined from measured values of first and second temperature sensors, values of the control chart and the code of the test sample holder. These parameters are used by the temperature regulating unit during the measurement.Type: GrantFiled: February 23, 2009Date of Patent: September 11, 2012Assignee: Dräger Safety AG & Co.

Patent number: 7374723Abstract: A device, process and system are provided for collecting and releasing a liquid sample, especially saliva. A defined saliva sample, i.e., a filtered, approximately homogeneously mixed saliva sample of a predetermined volume is made available in the simplest possible manner. A sampling tip (2) is provided made of a dimensionally stable and porous material, which is moved with its mouthpiece (4) in the mouth of a test subject for one to two minutes and takes up saliva based on the capillary action. A reagent liquid enters the pores of the sampling tip (2), mixes with the saliva there and is subsequently fed from a reagent depot by the action of pressure. The saliva and the reagent liquid are finally discharged as a droplet (40) in the filtered and mixed state, either into the cavity (10) of the sample collector or into a filter mixer.Type: GrantFiled: July 30, 2003Date of Patent: May 20, 2008Assignee: Dräger Safety AG & Co.
