Refer to shown in Fig. 5, Fig. 5 is that the conductivity of the urine of the utility model one embodiment measures schematic diagram, in the utility model, when for carrying out the measurement of a conductivity to a urine 90 to be measured, includes following steps:
First, start this switch element 70, by this power unit 50 supply this processing unit 40 operate needed for this power for operation, and this detecting device is placed in this urine 90, make this first electrode 10 contact this urine 90 with this second electrode 20, such as, make this urine 90 enter this measurement space 33, this first probe portion 11 is all contacted with this urine 90 with this second probe portion 21, and this measurement spacing between this first probe portion 11 and this second probe portion 21, form an electrical path 80.
Then, this processing unit 40, by the multiple ions transmitted in this electrical path 80 in this urine 90 of measurement, obtains this conductivity of this urine 90.About the measurement of this conductivity, refer to following explanation, this urine 90 includes urea, uric acid, protein, glucose, sodium, potassium, chlorine, Phos and calcium etc., wherein uric acid, sodium, potassium, chlorine, Phos and calcium etc. belong to electrolyte, be exist with ionic condition in this urine 90, namely this ion alleged by this case, after this first electrode 10 is energized with this second electrode 20, in this electrical path 80, this positive ion is to cathodic migration,, there is redox reaction respectively in negative this ion anode migration.
And the comprehensive conductive capability of electrolyte is called conductivity, represents, the inverse of conductivity i.e. resistance (R), that is: with L
L＝1/R (1)
The same with general solid conductor, electrolyte solution also observes Ohm law, and above formula (1) can be write as:
L＝1/R＝1/ρ.A/ι (2)
ρ is the resistance coefficient of solution or claims ratio resistance, and ι is the distance of electrode, and A is the solution sectional area of energising, and the inverse of ρ is called specific conductance or claims than conductance or conductivity, represents, that is: with κ
κ＝1/ρ (3)
So draw:
(unit is S.m to L=κ .A/ ι
-1) (4)
Because the conductivity of this urine 90 becomes positive correlation with renal function, its reason is, when normal renal function, the filtration rate of the glomerulus in kidney is relatively high, when glomerular filtration rate(GFR is relatively high, this urine 90 by electrolyte the more, namely represent conductivity higher; Otherwise when renal function generation problem, the filtration rate of the glomerulus in kidney is relatively low, when glomerular filtration rate(GFR is relatively low, this urine 90 by electrolyte fewer, namely represent conductivity lower.Therefore, this conductivity will measured from this urine 90 via this processing unit 40, is associated with the due conductivity data of renal function quality corresponding to one, can judges the renal function state being associated with this urine 90.In addition, change due to the conductivity meeting variation with temperature of a liquid, generally speaking, with 25 DEG C of normal temperature for standard, often rise or decline 1 DEG C, conductivity can rise or decline 2.1%, accordingly, this detecting device also can include a temperature sensing unit 100, this temperature sensing unit 100 is electrically connected with this processing unit 40, in the present embodiment, this temperature sensing unit 100 can be a thermistor, and can expose among this measurement space 33 and contact with this urine 90, measure the temperature of this urine 90 by this, temperature compensation (Automatic Temperature Compensation is carried out again by this processing unit 40, ATC), to calculate this correct conductivity.
At this, what further illustrate is, the setting of this first exterior wall 31 and this second exterior wall 32, it can intercept the portion disturbances being positioned at this urine 90 outside this measurement space 33 and producing, avoid the numerical value of this conductivity of gained significantly to beat, 33, this measurement space can be assisted this urine 90 to flow into this first exterior wall 31 and contact with this first probe portion 11 and this second probe portion 21 with in this second exterior wall 32.
In sum, because the utility model is by arranging this first electrode, this second electrode and this processing unit, and measured in this ion that this electrical path is transmitted in this urine, this renal function state of this urine is judged to be associated with this conductivity obtained.Accordingly, this detecting device is made to compare existing used test strip, not only can show and detect numerical value accurately, also have reusable, the advantage of use cost is not increased along with access times increase, and, the utility model compares the instrument that existing use quantitative analysis method detects uric acid, still possess the little advantage simple to operate of volume, the wish that the general common people carry out detecting can be improved, at any time for the health of oneself is checked on, moreover, the utility model is also provided with this first exterior wall, this second exterior wall and this measurement space, measure for this electrical path in this measurement space, avoid the measurement of this conductivity of disturbing influence that this urine is unnecessary outside this first exterior wall and this second exterior wall.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
