Body fluid testing device

A test cassette for housing test media for sampling body fluid, comprising:

• a section for receiving test media tape that is contaminated with past samples of the body fluid and an uncontaminated section;
• a housing including a supply portion in which the uncontaminated section of the test media tape is enclosed, the housing further including a storage portion in which a contaminated section of the test media tape can be enclosed, the housing defining an exposure opening at which the test media tape is exposed to the body fluid;
• wherein the test cassette further comprises a tip portion which guides the test media tape to expose a portion for body fluid application;
• wherein said tip portion extends at least partially outside said housing to guide the test media tape to a position external to said housing;
• wherein said tip portion has an illumination channel and a detection channel;
• a proximal end of said illumination channel has a light source to illuminate said test medium;
• wherein said test medium is located above a distal end of said illumination channel;
• and
• wherein light reflected from said test medium enters said detection channel and is received by a detector.

A body fluid testing device for analyzing a body fluid, comprising:

• a test media tape adapted to collect the body fluid,
• a supply portion for storing an uncontaminated section of the test media tape,
• a storage portion for storing a contaminated section of the test media tape,
• an exposure portion positioned between the supply portion and the storage portion, the exposure portion being adapted to expose a section of the test media tape to the body fluid;
• said testing device further comprising a light source for illuminating an area of the test media tape located within said exposure portion to guide a user for body fluid application;
• said body fluid testing device further comprising a housing with an outer contour and a tip portion over which said test media tape runs at said exposure portion;
• wherein said tip portion at least partially extends outside said outer contour of said housing;
• wherein said tip portion has an illumination channel and a detection channel;
• a proximal end of said illumination channel has a light source to illuminate said test medium;
• wherein said test medium is located above a distal end of said illumination channel;
• and
• wherein light reflected from said test medium enters said detection channel and is received by a detector.

A system for analyzing a body fluid, comprising:

• a body fluid testing device having a housing with an outer contour;
• a test media tape adapted to collect the body fluid;
• a supply portion storing an uncontaminated section of the test media tape inside the housing;
• a storage portion for storing a contaminated section of the test media tape inside the housing;
• a convex tip portion over which the test media tape runs between the supply portion and the storage portion;
• the convex tip portion at least partially projecting outside the outer contour of the housing to expose a section of the test media tape to the body fluid outside the housing of the body fluid testing device;
• wherein said convex tip portion has an illumination channel and a detection channel;
• a proximal end of said illumination channel has a light source to illuminate said test medium;
• wherein said test medium is located above a distal end of said illumination channel;
• and
• wherein light reflected from said test medium enters said detection channel and is received by a detector.
