Change the glucose in blood, there is layer protective layer on glucose oxidase surface, on the one hand can be reduced with guard electrode in blood
Biochemical substances cause to corrode to electrode, on the other hand glucose oxidase can be prevented to be lost in, and extend the service life of electrode.When
When working electrode 212 is without enzyme electrode, electrode surface not immobilized enzyme, the nano material with catalytic activity can be selected as Portugal
The catalyst of grape sugar reaction, such as Pt nano particle, Au, Pd noble metal and Ni and Cu metals and oxide, also CNT, stone
The nano materials such as black alkene, these materials are fixed on the surface of working electrode 212, equally also need one layer in these nano-material surfaces
Protective layer.Reference electrode 211, working electrode 212 and is connected pad 215 with electrode by electrode connecting line 214 to electrode 213 and connects
Connect, the material that electrode connecting line 214 connects pad 215 with electrode is gold.The size of electrode connection pad 215 is 200um-1mm.
As shown in figure 4, the silicon substrate surface of blood sugar test electrode 21 forms microflute 216, microflute 216 by deep etching process
Length be 1mm-10mm, depth 50um-200um, width 100um-1mm.Reference electrode 211, working electrode 212 and right
Electrode 213 is produced in microflute 216.When needing to carry out blood sugar test, patient punctures finger tip by disposable blood taking needle and extruded
Drop of blood, and finger tip drop of blood is placed to the eletrode tip of blood sugar test electrode 21, when microflute 216 touches drop of blood, because capillary is made
With blood can be automatically drawn into microflute 216, apply corresponding voltage on electrode, and the glucose in blood is consolidated in electrode surface
Fixed catalysis material, as glucose oxidase or nano material catalytic action under, you can produce corresponding electric current, pass through survey
Try size of current, you can measure the concentration of glucose in blood.
Fig. 5 is the schematic diagram that blood sugar test electrode 21 is fixed in electrode jockey 23, and electrode jockey 23 includes
Fixture upper piece 231 and fixture bottom sheet 232, the lower surface of fixture upper piece 231 have the electrode with blood sugar test electrode 21 to be connected pad
215 one-to-one signal connection pads 234.When blood sugar test electrode 21 is fixed in electrode jockey 23, blood glucose inspection
The electrode connection pad 215 on survey electrode 21 surface is just connected pad 234 with the signal of fixture upper piece 231 and aligns and be bonded tight
Close, system can put on voltage signal by the pad that is bonded up and down the reference electrode 211 of blood sugar test electrode 21, work electricity
Pole 212 and on electrode 213, signal caused by the glucose in blood can also be drawn by the pad being bonded up and down.Electrode
There is electrode clean fluid catheter through hole 233 on the fixture upper piece 231 of jockey 23, for fixed electrode cleaning liquor pipe 26.When
After blood sugar test electrode 21 carries out a blood sugar test, system control flows out a certain amount of electrode clean liquid 24 to blood sugar test electricity
The surface of pole 21 is cleaned, and convenient next time uses.
The blood sugar test electrode that existing blood glucose meter uses is disposable blood sugar test paper bar, patient's use cost compared with
It is high.The utility model devises a kind of MEMS blood sugar tests electrode, and electrode surface can be rinsed simultaneously by cleaning fluid after having tested
Dry, due to only 5 seconds or so the time tested every time, the loss during this to electrode is minimum, glucose oxidase or receives
Rice catalytic materials can be stablized in a dry environment preserves the long period, so the blood sugar test electrode in the utility model repeats
Use tens times.Serious diabetic need to measure 3-4 blood glucose daily, and in general patient only needs measurement once daily, or
Once, then the blood sugar test electrode in the utility model can be used continuously more than ten days to some months to person's measurement in several days.MEMS simultaneously
Processing technology can reduce production cost by mass producing, and the cost of electrode and disposable blood sugar test paper bar are close very
To lower, so as to greatly reduce the financial burden of patient.
The utility model adds blood sugar test function in insulin injection pen so that can be square before injection of insulin
Just blood sugar concentration is tested, and calculates and control automatically required insulin dosage according to the blood sugar concentration of patient instantly, from
And blood sugar concentration is more accurately controlled, ensure the glucostasis of diabetes patient.The refrigeration module of increased miniaturization can be easily
Insulin is refrigerated, ensures insulin active, while improve the portability of insulin cold storage plant.
It is to be not limited only to above-described embodiment for limitation of the present utility model, the utility model that above-described embodiment, which is not,
As long as meeting the requires of the utility model, the scope of protection of the utility model is belonged to.
