Can detect the biosensing apparatus of test piece sign indicating number and corpse or other object for laboratory examination and chemical testing lack of fill

Technical field

The present invention relates to a kind of biological sensing test sheet and its display processing unit, a kind ofly have Auto-Sensing test piece sign indicating number, and can detect the whether enough test piece the detected sign indicating numbers of corpse or other object for laboratory examination and chemical testing loading and the biosensing apparatus of corpse or other object for laboratory examination and chemical testing lack of fill but particularly relate to.

Background technology

Because sensor technology rapid development in recent years, the various biological sensors of ferment redox reaction that utilize constantly are suggested, and one after the other weed out the old and bring forth the new, wherein, again with the most species of the biological sensor of biomedical sector, for example: the blood sugar sensor, it can be in order to the blood-sugar content in the check blood, therefore, the blood sugar sensor becomes the important device of diabetic's self-checking, it can help the diabetic oneself to detect the concentration of blood-sugar content in the health, make the diabetic can momentarily note and control the blood sugar concentration in the health, blood sugar concentration is maintained within the normal scope, in case the patient finds that the blood sugar concentration of health is too high, just can be by diet, modes such as motion and insulin injection are come control of blood sugar content, yet these control modes must be just fair with employing under doctor's supervision and suggestion.

See also Fig. 1 and Fig. 2, be a kind of stereographic map of the existing blood sugar sensing apparatus of commonly using and a kind of exploded view of the existing blood sugar sensing test piece of commonly using, a kind of existing blood sugar sensing apparatus of commonly using 1 ', comprise: a blood sugar sensing test piece 12 ' and a processes and displays unit 10 ', wherein, this blood sugar sensing test piece 12 ' comprising: a strip substrate 122 ', a responding layer 124 ', a spacing body 126 ', an and cover plate 128 '.The front end of this strip substrate 122 ' is provided with an electrode part 1221 ', the top of this electrode part 1221 ' then is coated with this responding layer 124 ', this spacing body 126 ' and this cover plate 128 ' in regular turn, and, be provided with the corresponding electrode 1224 ' with of an operation electrode 1222 ' on the electrode part 1221 ', this operation electrode 1222 ' and this counter electrode 1224 ' are connected to one first lead 1226 ' and one second lead 1228 ' of strip substrate 122 ' tail end respectively.In addition, be covered in the responding layer 124 ' of electrode part 1221 ' top, it has the ferment enzyme can carry out the ferment redox reaction.

The diabetic states in this existing blood sugar sensing apparatus 1 ' of commonly using in the use, this blood sugar sensing test piece 12 ' is inserted among this processes and displays unit 10 ' earlier, then, the patient must handle display unit 10 ' with a test piece sign indicating number (strip code) input of blood sugar sensing test piece 12 ' earlier, then just can take the blood of own body, and blood directly dripped on this responding layer 124 ' of blood sugar sensing test piece 12 ', after electrochemical reaction after a while, processes and displays unit 10 ' just can change by reading the electric current that electrochemical reaction produces, and calculates the blood sugar concentration among the blood.
