For reaching major technique means that aforementioned purpose takes is that to make the test pieces of aforementioned blood material measurer be to comprise:
One insulating substrate;
The first/the second electrode is to be located on this insulating substrate;
One identification electrode is to be located on this insulating substrate;
One resistance is to be located between second electrode and identification electrode;
One responding layer is to be formed at appropriate location, base material stage casing, and is covered in an end of the first/the second electrode;
By above-mentioned design, in the test pieces that has a corpse or other object for laboratory examination and chemical testing is inserted into a blood material measurer, this blood material measurer can be exported fixed voltage to the second electrode, this voltage respectively the resistance by connecting second electrode and identification electrode, cover the responding layer of second electrode and first electrode, and on identification electrode and first electrode corresponding current signal of generation respectively; The current signal that to read on the electrode by identification with in the different current setting values that are built in this blood material measurer compare, to obtain electric current corresponding to this test pieces to concentration letter formula, the electric current that then current value of reading on first electrode is inserted in gained is to concentration letter formula, and then calculates the concentration of a corpse or other object for laboratory examination and chemical testing exactly.
Aforementioned connection identification electrode is complied with the precision resistance that different test pieces can be different resistances with the resistance of second electrode.
Another object of the present invention is that the test pieces of above-mentioned blood material measurer is being provided, its can cooperate the built-in different electric current that detects things to the blood material measurer of concentration letter formula in order to measuring blood, cholesterol, uric acid or triglyceride etc.
