  • Patent number: 5284770
    Abstract: A method and apparatus for verifying the operating accuracy of an instrument (10) for detecting the concentration of a medically significant component of a body fluid. The instrument (10) operates by determining the remission of a reacted chemistry contained on a substrate (106) after the chemistry has reacted with the medically significant component of the body fluid. The instrument (10) includes a radiation source (182), a radiation detector (300) and a pathway (164) from the radiation source (182) to the chemistry (106) and from the chemistry (106) to the radiation detector (300) when the substrate (106) is properly inserted into the instrument (10). The remission of the chemistry (106) determines the radiation detected by the radiation detector (300).

  • Patent number: 5277870
    Abstract: A portable blood chemistry monitoring meter that employs an analog circuit in conjunction with a manually adjustable potentiometer to locate a null position that balances the measure taken of the blood chemistry-induced changes in the chemistries of disposable test strips. The meter displays in pre-printed, man-readable format blood chemistry concentrations that are individually calibrated to the specific batch-lot chemistries of the disposable test strips used with the meter. In a preferred embodiment, the meter is a blood glucose monitoring meter.

  • Patent number: 5246858
    Abstract: A method and apparatus (10) for determining the remission of a chemistry (106) which reacts with a medically significant component of a body fluid. The remission of the chemistry (106) changes as it reacts. The method and apparatus (10) include irradiating the chemistry (106) with a radiation source (182), detecting remissions of radiation from the chemistry (106) with a radiation detector (300), providing a radiation pathway (164) between the source (182) and the chemistry (106), providing a remission pathway (164) between the chemistry (106) and the detector (300), and detecting the rate of change of remission of the chemistry (106) with respect to time.

  • Patent number: 5232668
    Abstract: An instrument for analyzing test strips supporting chemistries which react with a medically significant component of a body fluid to indicate the concentration of the component in the body fluid. The instrument includes a pathway along which radiation is guided from a radiation source to a strip when the strip is inserted into the instrument and along which remission is guided from the strip to a radiation detector. A title provided on the instrument provides a first remission when no strip is inserted into the instrument. The tile is separated from the radiation source by the strip when the strip is inserted into the instrument. The first remission and the strip's remission, respectively, indicate the absence and the presence of the strip in the instrument. The strip also has a surface opposite the chemistry supporting surface characterized by a second strip remission different from the first strip remission.

  • Patent number: 5174963
    Abstract: A portable blood glucose monitoring meter that employs an analog circuit in conjunction with a manually rotatable dial that varies the resistance of a potentiometer to locate a null position that balances the measure taken of the blood glucose-induced changes in the chemistries of disposable test strips. The dial supports a replaceable, pre-printed, man-readable calibration disk. The calibration disk displays in man-readable format blood glucose concentrations in milligrams per milliliter calibrated to the specific batch-lot chemistries of the disposable test strips used with the meter. A patient places a replaceable batch-lot calibration disk upon the dial, and inserts a corresponding test strip bearing a drop of capillary blood into the meter. The patient then manually adjusts the dial until prompting arrows indicate a null position. If the dial has rotated past the null position, an opposing arrow will illuminate indicating a need to rotate the dial in the opposite direction.

  • Patent number: 4793104
    Abstract: A one-piece guide adapted to be inserted into mortar, between recessed surfaces presented by opposing faces of adjacent glass blocks, to space and align them with respect in each other in the formation of a masonry structure. The guide comprises a relatively thin frame including longitudinal and transverse arms having joined to their free ends bodies that are spaced transversely from said each other a distance only slightly less than the width of said recessed face surfaces.

  • Patent number: 4205088
    Abstract: Pharmaceutically-acceptable compositions containing, as an active ingredient, at least one N-acylanilinobutyric acid have uses unrelated to the choleretic activity suggested in U.S. Pat. No. 3,780,095. Moreover, the further uses generally involve administration of smaller doses than would be required to obtain a choleretic effect.The new uses include: (a) increasing the gastrointestinal enzyme secretion and (b) tonicizing the cardiovascular system. The increase of the gastrointestinal enzyme secretion is applied in the treatment of different diseases, such as treatment of sprue, treatment of indigestion, treatment of acute and chronic pancreatitis, therapy for degenerated intestine mucous membrane, treatment of stomach spasms, treatment of stomach ulcers, treatment of diseases where the application of an antigastrin is indicated. The tonicising of the cardiovascular system is applied in, e.g.
