Portable digital reader for urinalysis

摘要

The present invention relates to a portable digital reader for reading an analysis target chip including a plurality of test areas. The reader comprises: a light emitting section having light emitting elements for radiating light; an integral optical splitter for uniformly distributing the light from the light emitting section to each test area of the analysis target chip; a light receiving section for receiving light reflected from each test area so as to convert the same into electric signals; and a measuring section for measuring concentration according to the electric signals obtained from the light receiving section. Therefore, it is possible to prevent the generation of errors in signal measurement due to optical distribution failure by assembling branch sections of the optical splitter under the control of the number of the branch sections according to the number of test items in a test strip.

主权项

1. A portable digital reader for reading a target chip including a plurality of test regions, the portable digital reader comprising:
a support configured to receive the target chip; a light emitter including light emitting elements and emitting light; an integrated light distributor comprising:
a stem part extending from the light emitter in a traveling direction of the light, the stem part being configured to reflect light from the light emitter; anda plurality of branch parts extending toward the support from the stem part;wherein a surface of the stem part has a predetermined curvature based on a distance between branch parts to totally reflect the light incident on the stem part toward the branch parts, the light incident on the stem part being distributed to the target chip through a branch part; a light receiver configured to receive the light, which is reflected from each test region, and convert the received light into an electric signal; and a measuring part configured to measure a concentration based on the electric signal received from the light receiver.
