Description
Technical field
The present invention relates to information identificating unit and biology sensor, and in particular to the information identificating unit of medical test and
Biology sensor.
Background technology
POCT (detection immediately) is Point of Care Testing abbreviation, is the sub-line of in-vitro diagnosis (IVD) industry
Industry.By simplifying design and technological innovation, it is convenient, quick in patient's site inspection at one's side that POCT is realized, quick to obtain diagnosis knot
Really.Current POCT products have been widely used in hospital ICU, operation, emergency treatment, clinic and patient family, can be carried out absolutely mostly
The detection of number routine clinical index.As the POCT products that occupation rate of market is maximum, blood sugar test system can realize that patient exists
The selftest of family, monitors blood sugar concentration in real time.
Aborning, because the influence of the factors such as environment, technique causes there is the inconsistent of performance per a collection of blood glucose product,
Influence blood glucose test result.Blood glucose production enterprise all can be that one group of generation is set per batch of blood glucose product before product export
Code is used for correcting test result, to ensure the accuracy of test result.
Blood glucose meter on the market typically uses following two code identification methods at present：
-, user adjust code manually.Every bottle of test paper marks code information when dispatching from the factory.User manually adjusts the code of blood glucose meter
It is whole to the code information that is marked on test paper bottle.However, manual bar code operation is complex, user easily occurs code adjusting wrong
Phenomenon, especially using blood glucose meter be generally the elderly, error probability it is higher, easily cause the problem of testing result is inaccurate.
2nd, recognized using code chip.Every bottle of test paper additionally encloses a block code chip when dispatching from the factory.Code information is stored
In code chip.In detection process, code chip is first inserted into blood glucose meter, then user's insertion test paper is detected, blood
Sugared instrument reads the code information in code chip, so as to carry out calibration of the output results, provides accurate test result.Code chip is recognized
Mode avoids the manual errors that manual bar code is produced.It is separated packaging yet with chip and blood glucose meter, is changing different batches
Number test paper when need to change corresponding chip, this process often passes into silence, so as to cause the inaccurate of testing result.And
And because chip is smaller, be easily lost, once Die missing, user will be unable to be detected using test paper, and a whole bottle examination
Paper will all be wasted.
Regarding to the issue above, three kinds of novel test papers are occurred in that on the market now, its test paper has code information in itself.
The first is resistance value or resistance ratio identification.Different length and the resistance of thickness are printed with test paper, so that
So that the resistance or ratio of resistance are different, different resistances or the different code information of ratio correspondence.
Second is logic identification.Increase electrode group carrys out the test paper of representative code information.By in newly-increased electrode group
It is etched so that electrode connection or cut-out to carry out electrode group binary coding, or by beating real hole or void hole, and or
Person sets the sawtooth of different conditions to carry out binary coding on electrode.
The third is optical identification.Enter line code by printing different color blocks, bar code either figure on test paper
Identification.
If the first and second of test paper will realize that more coding information needs more electrodes (or contact), so
Just there is higher demand to the size of test paper, increase the cost of test paper.
The third need blood glucose meter have a single optical device be used for encoded signal identification, increase cost.
