Abstract
A measuring device for measuring the concentration of a substance in a liquid, especially a body liquid, is designed for use with a test card having test sections with test fields located next to one another in the longitudinal direction of the card. The device has a housing for receiving one or more test cards and has an exposed test card support surface providing a measuring station with a measuring opening through which optical or electrical sensors sense the test field of a test section of a test card. A hand actuatable transport mechanism, which may be an actuating lever, a transport roll or a transport belt is engageable with a test card in the housing to advance it forwardly to bring a test section to the measuring station. The housing for the device is made of upper and lower portions which may be movable relative to one another with that movement used to drive the transport mechanism. The device also includes a hand operable apparatus for cutting a used test section from the test card and various means are provided for inhibiting the test fields of the cards contained in the housing from coming into contact with ambient air in order to prevent the moisture and/or other factors in the ambient air from negatively influencing the usefulness of the test sections.
