Abstract
The invention provides an ion concentration data acquisition and processing method for a blood gas electrolyte analyzer. According to the method, an ion concentration measurement result can be obtained by the steps of continuously acquiring ion concentration data with the same time interval, determining a base point value, selecting the ion concentration data and calculating the ion concentration data. The method is simple in step and accurate in measurement result.
Description
Technical field
The invention belongs to medical instruments field, particularly a kind of ion concentration data acquisition and disposal route of vim and vigour blomelicalbloodgasandelectrolrteanalyzers.
Background technology
Electrolyte plays an important role in the process of keeping human body organismic internal environment balance and normal physiological function.Plasma sodium accounts for 92% of plasma ion total amount, accounts for 90% of osmotic pressure, so plasma sodium plays a decisive role to osmotic pressure, is subjected to the adjusting of hypothalamus, posterior pituitary and kidney.Potassium accounts for 98% of total amount in cell, the irritability of keeping the osmotic pressure of intracellular fluid, capacity and metabolism, acid base equilibrium, neuromuscular cell membrane and keep the cardiac muscle normal function all have great importance.Cl is negative ion main in the extracellular fluid, and the Ca ion is the main composition thing of bone, and contraction of muscle, blood clotting are had regulating action.Clinically, in the mensuration blood promptly and accurately electrolyte such as potassium, sodium and chlorinity can judge electrolyte ask the way Oh, acid-base imbalance, be used for the guidance treatment of multiple disease, regulate water, electrolyte balance.
K, Cl and Ca plasma concentration generally adopt blomelicalbloodgasandelectrolrteanalyzers or vim and vigour blomelicalbloodgasandelectrolrteanalyzers in the present a lot of detection blood.Then, ion concentration data acquisition and the disposal route accuracy of existing vim and vigour blomelicalbloodgasandelectrolrteanalyzers are lower, are difficult to meet the requirement that existing medically ion concentration detects.
Summary of the invention

N-1|≤a, then t
N-1Be the basic point value;
If, | t
n-t
N-1|＞a, then t
nBe the basic point value;
Step 3, the ion concentration data are selected: two methods are calculated continuously set by step, get the one group of ion concentration data that satisfy following requirement: t
mBe the basic point value, and should organize in the ion concentration data | t
M+l-t
M+l-1|≤a all sets up;
Step 4, the calculating of ion concentration data: one group of ion concentration data that step 3 is selected are averaged, be the PCO2 measurement result.
As preferably, described ion is potassium ion, sodion, calcium ion, chlorion and pH value.
Preferred as another kind, in the step 1, be the 500-700 millisecond interval time.
Preferred as another kind, in the step 2, a is 2-4.
Preferred as another kind, in the step 3, the quantity of these group ion concentration data of selection is 5-7.
Beneficial effect: the ion concentration data acquisition of vim and vigour blomelicalbloodgasandelectrolrteanalyzers provided by the invention and process method step is simple, measurement result is accurate.
