Description

Blood gas analysis colorimetric card

Technical Field

The utility model relates to the technical field of blood gas analysis instruments, in particular to a blood gas analysis colorimetric card.

Background

Acid-base imbalance of human body is a pathophysiological process frequently encountered in clinic and often becomes a direct cause of death of patients. Therefore, timely and correct analysis, judgment and processing are often the key to success or failure of treatment. In order to maintain the acid-base balance of human body, the pH value is kept between 7.35 and 7.45, and is mainly regulated by lung and kidney. At present, the clinical blood gas analysis generally measures the values of hudrogen acid or hudrogen base and acid generation or base generation, namely PaCO2 and HCO3, of a human body by using a blood gas instrument, and then uses a Henderson-Hasselbalch equation (H-H equation for short): PH ═ PK + LogHCO3-a.PaCO2] ] > calculation of the PH value, and then analysis and comparison of the acid-base imbalance of the human body are carried out to determine the type of the acid-base imbalance. Because the equation is a logarithmic equation, direct calculation is time-consuming and cumbersome, and is difficult to be used clinically. There are many scholars who make diagnostic schemes for various acid-base conditions based on the relationship of three variables in the H-H equation, but they are mainly suitable for diagnosis of simple acid-base imbalance and difficult to deal with in complex clinic. Some researchers advocate using a compensation prediction formula, but the method is simple, but the two variables, i.e., PaCO2 and HCO3, are processed by considering the curve relationship as a straight line relationship, so that the error between the judgment result and the clinical actual condition is large.

The prior patent (publication number: CN 2540635Y) provides a blood gas analysis ruler, which is designed according to an (H-H) equation and is in a slide rule form, and consists of a lower fixed ruler marked with a pH value scale, an upper fixed ruler marked with an HCO 3-value scale and a slide ruler marked with a PaCO 2-value scale, wherein the upper fixed ruler, the lower fixed ruler and the slide ruler are corresponding to each other in normal physiology HCO 3-24, PH7.4 and PaCO240, a vernier marked with an anion gap AG value scale is arranged on the upper edge of the upper fixed ruler, the starting scale of the vernier is '16', the structure is simple, the use is convenient, the analysis is rapid and accurate, and the slide ruler is suitable for clinicians and blood gas analyzers.
