Handheld hemoglobin detecting device

A handheld hemoglobin detecting device comprising:

• a housing assembly including
• a holding base;
• a tubular housing extending from the holding base and having a through hole formed through a distal end surface of the tubular housing;
• and
• a liquid holder spaced from the distal end surface of the tubular housing, attached to the tubular housing via at least one connecting bar, and having a light reflector disposed in the liquid holder;
• a control module disposed on the housing assembly and including
• a micro-controller;
• a switch electrically connected to the micro-controller and alternatively switching the micro-controller on or off;
• a light sensor electrically connected to the micro-controller;
• and
• a display interface electrically connected to the micro-controller;
• and
• a lighting assembly mounted in the tubular housing and including
• a light emitting module electrically connected to the micro-controller and having at least one light source;
• a light concentrator disposed between the light emitting module and the liquid holder, wherein at least one light beam emitted from the at least one light source passes through and is concentrated by the light concentrator to shine on the liquid holder;
• and
• a light guide mounted through the light emitting module and the light concentrator.
