Analysis treatment.With this repeatedly, until treatment end.
Hereinafter, to how on-line determination Urea clearance index is described in detail.
The haemodialysis equipment of on-line determination Urea clearance index of the invention is measured by the first conductivity measuring appliance 41
Into the conductance angle value of the dialyzate of dialyzer 40, the dialysis flowed out from dialyzer 40 is measured by the second conductivity measuring appliance 42
The conductance angle value of waste liquid.The two conductance angle value that will be measured compare, so as to calculate the elimination effect of Na ions, so as to calculate
Go out the elimination effect of urea.
Conductance angle value is essentially Na ion concentrations in dialyzate, therefore, the conductance of the measurement of the first conductivity measuring appliance 41
Angle value be essentially into dialyzer 40 dialyzate Na ion concentrations, i.e. dialyzate interacted with blood samples of patients before conductance
Angle value;The conductance angle value of the measurement of the second conductivity measuring appliance 42 is essentially the Na ions of the dialysis waste liquid flowed back to from dialyzer 40
Concentration, i.e. dialyzate interacted with blood samples of patients after conductance angle value.For theory, and the dialyzate before blood samples of patients interaction
Middle Na ion concentrations are low, and Na ion concentrations are high in blood samples of patients, therefore, Na ion concentrations can be because dispersion in dialysis waste liquid
And raise, specific elevated amount just can indication go out transhipment situation of the Na ions by pellicle, hold dialyzate conductivity and
The difference of dialysis waste liquid conductivity just can learn transhipment situation of the Na ions by pellicle.
Due to by conductivity measuring appliance conductance angle value measured directly it is smaller, change it is smaller, thus it can be difficult to hold
Firmly small change, therefore, in one embodiment, the first plunger displacement pump 51 and the second plunger displacement pump 52 can be improved, so as to improve concentration
The suction ratio of liquid A and concentrate B, thus improve the dialyzate conductance angle value into dialyzer.
Current urea clearance K can be calculated according to following formula one.Wherein, Qd is dialysate flow, and it is to set
Fixed treatment parameter, cdi is the conductance angle value of the dialyzer entrance point measured by the first conductivity measuring appliance 41, and cdo is by
The conductance angle value of the dialyzer port of export of the measurement of two conductivities measurement 42.Cdi1 and cdo1 is the first plunger displacement pump 51 and second of raising
The conductance angle value at the time point before plunger displacement pump 52, i.e. valley value, cdi2 and cdo2 are raising the first plunger displacement pump 51 and the second post
Conductance angle value after plug pump 52, i.e. crest value.The present apparatus in use, the first conductivity measuring appliance 41 and the second conductivity
Measurement 42 is constantly detected, when needing to carry out urea clearance measure, raising the first plunger displacement pump 51 and the second plunger displacement pump 52
Soakage so that the first conductivity measuring appliance 41 and the second conductivity measurement 42 detected value there is crest, that is, rise peak S1
With rising peak S2.As shown in figure 4, rise peak S1 there is obvious difference with peak S2 is risen, and there is delayed phenomenon, i.e.
Rise peak S2 and lag behind rising peak S1.The present apparatus will be extracted and rise peak S1 and rise the corresponding conductance angle value of peak S2, i.e. cdi2 with
cdo2。
According to the setting of doctor, measurement (such as 30 minutes) is carried out once every time rating, in measurement process
The first plunger displacement pump 51 and the second plunger displacement pump 52 are improved, the one-shot measurement time is shorter, about within 1 minute, the imbibition ratio of raising
10% or so, because time of measuring is short, increase rate is not too high, therefore, although the rising of dialyzate conductivity can be caused,
But do not interfere with therapeutic effect.
After calculating K values, Kt/V, i.e. Urea clearance index can be calculated, wherein t is from starting treatment to this measurement
Time, V is body surface area.
Wherein, body surface area V can be calculated according to equation below two, and formula two is also called Watson formula, its with
The height of patient, sex, age, body weight are information-related.
Formula two:
Thus, it is possible to calculate the Kt/V values of patient, as Urea clearance index.
In sum, haemodialysis equipment of the invention is by the first conductivity measuring appliance and the second conductivity measuring appliance point
The conductance angle value of the dialysis flowed back into dialyzer and from dialyzer is not measured, determines and calculate the clearance rate of Na ions, by
It is coincide very much by the transhipment situation and urea of pellicle in Na ions, therefore, the clearance rate of Na ions can be similar to urea
Clearance rate, so as to obtain Urea clearance index, embodies the elimination effect of small molecule, understands the situation of blood purification treatment effect.
