Abstract:
A light-transmittance meter (10) employs a housing (12) that forms a slot (16) in which the edge of a window pane (14) can be received. A microswitch (24) detects initial insertion of the window (14) into the slot (16) and causes a sample-and-hold circuit (32) to store a value representing the output that a photodiode (20) produces in response to light received from a light-emitting diode 18 before the window pane (14) is interposed between them. A ratio meter (36) then receives the output of the photodiode (20) when the window (14) has been interposed between the LED (18) and the photodiode (20), and it generates a display (22) of the ratio of that value to the initial, reference value determined before the window 14 was completely inserted.
Abstract:
A process for producing an analytical aid for the detection of at least one analyte in a sample, such as a body fluid. The analytical aid includes at least one housing and at least one test element including at least one test chemistry. The process includes the following steps: providing the test element; and producing at least one housing part of the housing at least one shaping process, during which the test element is connected to the housing part.
Abstract:
A measurement device includes a housing and at least one display integrated in the housing. The housing includes a recess adapted for insertion of a cartridge into the housing to deliver a sample to be measured to the device. The recess has an opening at the front of the housing and a first part of the housing for insertion of the cartridge protrudes in a direction enclosing an angle with a second part of the housing.
Abstract:
Measuring device (1; 15) for determining the composition of the liquid phase of a liquid-gas mixture includes a duct (2) defining a flow direction (X) of the mixture parallel to the longitudinal development axis (Y) of the duct (2) and a measuring element (4) arranged in the duct (2) and suited to determine the composition of a liquid layer that flows in contact with the internal surface (3) of the duct (2). The internal surface (3) of the duct (2) includes an intercepting surface (5, 5′) suited to convey part of the liquid layer towards the measuring element (4), arranged so that it is incident on the flow direction (X) and developed according to a conveyance trajectory that has a helical section and whose tangent to the outlet end (7, 7′) intersects the measuring element (4).

Abstract:
A drug disposal and verification device includes a first chamber and a second chamber. The first chamber has an injection port for receiving wasted drug solution and a disposal volume. A positive displacement flow measuring device positioned between the injection port and the disposal volume is used to measure the volume of wasted drug solution injected into the device. The positive displacement flow measuring device is also adapted to divert a small portion of the wasted drug solution to the second chamber. The second chamber holds a breakable test reagent ampule for quantitative testing of the wasted drug solution. The disposal volume of the first chamber may include at least one test strip for qualitative testing of the wasted drug solution.
Abstract:
An automatic optical measurement system (100) is provided. The measurement system (100) includes a sample vial (10) and an automatic optical measurement apparatus (90) configured to receive the sample vial (10). The automatic optical measurement apparatus (90) is configured to detect a presence of the sample vial (10) in the automatic optical measurement apparatus (90) and measure a light intensity of light substantially passing through the sample vial (10) if the sample vial (10) is present. The measured light intensity is related to sample material properties of a sample material within the sample vial (10).
Abstract:
Provided is a liquid sample analysis chip reading system. The reading system includes an analysis chip, a light emitting part, a plurality of light wave-guides, and a light receiving part. The analysis chip includes a plurality of detecting parts. The light emitting part includes three light sources emitting light having wavelengths (or colors) different from each other. The plurality of light wave-guides irradiate the light emitted from the light emitting part onto the plurality of corresponding detecting parts, respectively. The light receiving part includes a plurality of light receiving devices for receiving the light having a specific color reflected from each of the plurality of corresponding detecting parts of the analysis chip. The three light sources are discontinuously controlled to emit light onto the plurality of light wave-guides.
