Embodiment Construction

[0018] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] The ion concentration data acquisition and processing method of the blood gas electrolyte analyzer comprises the following steps:

[0020] Step 1, use the ADC (Analog-to-Digital Converter) device to continuously collect ion concentration data at intervals of the same time to obtain a set of ion concentration data, respectively t 1 , t 2 , t 3 ... t n ; In the present invention, the interval time is 600 milliseconds, and the interval time can also be reasonably set as required, preferably 500-700 milliseconds;

[0021] Step 2, determine the base point value: t 1 As the initial base point value,

[0022] If,|t n -t n-1 |≤a, then t n-1 is the base point value;

[0023] If,|t n -t n-1 |>a, then t n is the base point value;

[0024] a is set to 3, optionally, it can also be set reasonably according to needs, preferably 2-4;

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 [0001] The invention belongs to the field of medical devices, in particular to a method for collecting and processing ion concentration data of a blood gas electrolyte analyzer. Background technique [0002] Electrolytes play an important role in maintaining the balance of the internal environment and normal physiological functions of the human body. Plasma sodium accounts for 92% of total plasma ions and 90% of osmotic pressure, so plasma sodium plays a decisive role in osmotic pressure and is regulated by hypothalamus, posterior pituitary and kidney. Potassium accounts for 98% of the total in cells, and it is of great significance in maintaining the osmotic pressure of intracellular fluid, capacity and substance metabolism, acid-base balance, stress of neuromuscular cell membranes, and maintaining the normal function of myocardium. Cl is the main anion in the extracellular fluid, and Ca ions are the main constituents of bones, which regulate muscle contrac...
