Abstract
A tape unit is provided comprising a flexible tape, a spool for unwinding unused tape and a spool for winding on used tape, wherein an intermediate section of tape which is located between the spools can be used by a user. The tape unit generally achieves a compact design by providing one of the spools in a receiving area defined within the other spool, and a deflection guide for guiding the tape from one spool to the other.
Claims18
A tape unit comprising a tape coiled around an unwind spool and a take-up spool and having an intermediate section of tape located between the spools and positioned by the tape unit for use by a user, wherein one of the unwind spool and the take-up spool comprises an outermost spool and defines a receiving area, and wherein the other of the unwind spool and the take-up spool is provided within the receiving area.
A diagnostic system for performing a diagnostic analysis on a test fluid, the system comprising tape unit comprising a tape coiled around an unwind spool and a take-up spool and having an intermediate section of tape located between the spools and positioned by the tape unit for use by a user of the system, wherein one of the unwind spool and the take-up spool comprises an outermost spool and defines a receiving area, and wherein the other of the unwind spool and the take-up spool is provided within the receiving area, the tape comprising a plurality of sections each having an analytical test field, and wherein the tape unit is configured and arranged with an application site at which the test fluid can be applied to successive test fields in the intermediate section as the tape is advanced from the unwind spool to the take-up spool, and wherein at least one of the spools is configured for being rotated by a motor or by manual means.
