Joint testing type test paper strip for simultaneously measuring parameters of two types of blood and preparation method and application thereof

Abstract

The invention discloses a joint testing type test paper strip for simultaneously measuring parameters of two types of blood and a preparation method and application thereof. The joint testing type test paper strip comprises a substrate layer, wherein a first electrode layer, a first middle separating layer and a first coverglass are sequentially arranged under the substrate layer from top to bottom; a second electrode layer, a second middle separating layer and a second coverglass are sequentially arranged above the substrate layer from bottom to top; the first middle separating layer and thesecond middle separating layer are respectively provided with a first reaction cavity and a second reaction cavity. The joint testing type test paper strip has the advantages that by designing the tworeaction cavities, the blood is fully impregnated into the two cavities, and the two biochemical indexes are measured; by designing multiple reaction cavities, the multiple biochemical indexes can besimultaneously measured; the first electrode layer comprises two pins, so as to avoid the inaccuracy in measuring of the blood biochemical parameters due to incomplete filling of the two reaction cavities by the blood.

Description

technical field [0001] The application belongs to the field of biosensing technology, in particular, it relates to a test strip for simultaneous measurement of two blood parameters and its preparation method and application. Background technique [0002] According to China's epidemiological statistics, there are nearly 100 million people with hyperlipidemia in China, 160 million people with dyslipidemia, and more than 92.4 million people with diabetes. On average, every 30 seconds someone suffers from diabetes, and on average, at least one person dies every 30 seconds. in cardiovascular disease. 77% of the increase in mortality from coronary heart disease in China is due to elevated cholesterol. Every 31mg / dL reduction in low-density lipoprotein cholesterol (LDL-C) can reduce all-cause death by 12%, reduce major cardiovascular events (such as myocardial infarction, stroke, coronary heart disease) by 21%, and reduce coronary heart disease mortality by 19%. The mortality rat...

Problems solved by technology

Similar to blood routine, blood lipids, blood pressure, blood sugar, heart rate, acid-base environment in the human body, etc., and these indicators need to go to a professional hospital and use professional measuring instruments to measure them. For sub-healthy people or patients with corresponding diseases In other words, the above measurement is very inconvenient. Therefore, some household disposable test strips have appeared on the market, such as blood glucose test strips and blood lipid test strips. However, these test strips have single functions and are used alone when used. Simultaneously realize the measurement of blood sugar and blood lipid

Especially for patients suffering from hyperlipidemia and hyperglycemia at the same time, it is necessary to collect secondary blood to measure blood glucose and lipid parameters at the same time, which increases the pain of patients
