Description
Technical field
The utility model relates to a kind of external diagnosis reagent, is specifically related to a kind of and the matching used glucose in urine test-strips of glucose in urine tester.
Background technology
In order to control metabolic situation,, need the concentration of glucose in the control volume circulation termly particularly for diabetes cases.This is necessary for the type i diabetes patient who wants insulin injection not only, also is that so the latter accounts for 85% of this glycometabolism disease for the type ii diabetes patient.According to expectation, to world diabetic number in 2010 will reach 200,012,100 (Hauner, H; DtschMed Wochenschr (German medical science weekly) 1998; 123; 777-82; Pharmaco Economlcs (medication economics) 1995; 8 (Suppl, I) 28-71; ).
In view of the high incidence of diabetes, conventional needs and the hope that blood glucose measurement that skin penetrating carries out can not satisfy regular metabolism control of passing through is only arranged.This needs the patient to overcome the mental handicape of stabbing skin before each the measurement.For Most patients, do not need measuring blood, and as long as the concentration of glucose in the control urine.If surpassed the threshold value of kidney by metabolic stimulation, just cause the glucose outside the physiological requirements to be discharged through kidney as glucose in urine, the glucose in urine just is presented as can detected concentration.Therefore, although blood sugar test is quite universal, glucose in urine detects as a kind of very easy noninvasive detection method of operation of using, and still is subjected to considerable part diabetic's welcome deeply.
A kind of characteristic of measuring the method for glucose in urine based on glucose makes light polarization and dextrorotation.Said polarization photometer has just utilized this specific character, and wherein light is estimate (Poege, A.W.Z med.Labortechnik (medical experimental chamber diagnostic techniques) 17 (1976) 59-79) of actual concentration of glucose from the angle of plane of polarization deflection.
Usually adopt glucose in urine to detect test paper for the screening family of prevention usefulness and the method for the glucose content in the human urine, this class test paper majority is the color reaction that produces the glucose compliance on the zymochemistry basis.The shortcoming of these test strips is poor accuracy, the half-quantitative detection that can only be used for glucose in urine, and remolding sensitivity is lower, generally all reach 50mg/dl at glucose in urine content, even 100mg/dl just can demonstrate the positive, also must be with accurate judged result of strict control time of clock during test, thus measurement result is very unreliable.And have only the people that can differentiate color to adopt, and among diabetic's, particularly type ii diabetes the gerontal patient, considerable people is a colour blindness, it is inaccurate to debate look at least.
Above-mentioned polarization photometer is the clinical chemistry that is used for that is equipped with as laboratory equipment, and the glucose of expressing reliably in the daily metabolism control in the urine exists and the conventional method of concentration and Tes-Tape is not suitable for being used as.Therefore research and development more and more concentrates on enzymatic-electrochemical measuring device and the application aspect glucose assays thereof.2008, a kind of biology sensor glucose in urine tester that can carry out detection by quantitative to glucose in urine has been released in a company's development of Japan, but because it adopts the fixation of sensor detection head, cost an arm and a leg, the use cost height, and detection head is repeatedly to use repeatedly, needs to clean, and also can face some problems of sterilization aspect.

For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of glucose in urine test-strips, comprise substrate, substrate is provided with three strip conductive electrodes, be respectively anode electrode, cathode electrode and short-circuiting electrode, short-circuiting electrode wherein and anode electrode or cathode electrode join, part is provided with dielectric isolation layer so that the electrode conducting part of conductive electrode front end is exposed outside on conductive electrode, offer the reaction window on the described dielectric isolation layer, the span of this reaction window is while covered cathode electrode and anode electrode, is pasted with the enzyme reaction film in the reaction window; On described dielectric isolation layer, be provided with a bonding dividing plate, offer the thief hatch, the siphon that are interconnected on this dividing plate and lead the sample groove, wherein thief hatch is arranged at the end away from substrate top electrode conducting part, siphon lead the sample groove to offer on position and the dielectric isolation layer reaction position of window corresponding.
For making whole test-strips more attractive in appearance, the operation of also being more convenient for simultaneously can be pasted a surface encapsulation plate on described bonding dividing plate, leads the gas port that the sample groove communicates but must offer on bonding dividing plate with siphon this moment, and this gas port runs through the narrow end of bonding dividing plate; Or gas port is offered in the corresponding position of leading the sample groove with siphon on described surface encapsulation plate.
Described reaction window is the square groove that be arranged in parallel with dielectric isolation layer.
Be simplified design, described siphon can be led the sample groove and extend until the termination of bonding dividing plate, thereby form the thief hatch on this bonding dividing plate in this end towards direction away from substrate top electrode conducting part.When product is such design, when testing, preferably adopt the mode that test-strips is immersed in the urine sample to take a sample.
Having in this glucose in urine test-strips under the situation of surface encapsulation plate, generally is that described thief hatch is opened in the end that the sample groove is led in siphon, and gas port is opened in the front end that the sample groove is led in siphon.Offer and the corresponding thief hatch of thief hatch shape cave with corresponding position, thief hatch position this moment on described surface encapsulation plate, so that the splashing into of urine sample.Can certainly on substrate, offer and the corresponding thief hatch of thief hatch shape cave with corresponding position, thief hatch position.
Described thief hatch can be designed to difformity as required, is generally circle or semicircle.
Compared with prior art, the utility model glucose in urine test-strips has realized the high sensitivity quantitation detection when keeping traditional Tes-Tape not have wound detection advantage.The supporting use of glucose in urine tester of this product and applicant's development, easy and simple to handle, the test effect is quicker, accurate, reliable.
