Problems solved by technology

However, the test strip production process based on screen printing technology has its inherent limitations, including the uncertainty of raw materials (such as carbon, silver paste, stencil, etc.), low production efficiency, and easy to be polluted during the production process.
On the one hand, this affects the consistency and accuracy of products, on the other hand, it restricts the expansion of production scale

Embodiment Construction

[0026] The whole blood lactic acid detection test strip of the invention is an electrochemical biosensor. figure 1 is a perspective view schematically showing the structure of an electrochemical biosensor according to the present invention. From figure 1 As can be seen in the figure, the electrochemical biosensor of the present invention includes an insulating substrate 1, on which a pair of conductive strips 2a, 3a parallel to each other are formed along the length direction by using the method of shadow mask and metal film deposition process. , The area and shape of the conductive strips 2a, 3a can be controlled by the mask, and the conductive strips 2a, 3a formed by this method have a more precise electrode three-dimensional structure compared to traditional methods such as screen printing and thick wire bonding. One end of the conductive tape 2a, 3a is used as the access end 7 and 8 of the insertion testing instrument, and a spacer 4 with a three-dimensional size is paste...

Abstract

A test bar of whole blood lactate is an electrochemical biological transducer including substrate, isolation plate, two conductive belts , operating electrode and counter electrode , reagent layer for reaction and reaction area . The transducer reaction area can quickly detect out lactate content in blood without manual work .

Description

technical field [0001] The invention relates to the technical field of biological detection, and relates to an electrochemical biosensor test strip for quantitative detection of whole blood lactic acid, a production method and a detection technology for mass production thereof. Background technique [0002] In the past, lactic acid in blood was mainly carried out on large-scale blood biochemical analyzers. Due to the need to use special equipment, the measurement requires more blood, takes a long time, and is expensive. It is suitable for large hospitals. In recent years, the use of enzymes has Various types of biosensors with specific catalytic effects have been developed. Since this type of biosensor does not need any pretreatment before detection, it can accurately measure the lactic acid content in whole blood in a relatively short period of time. Moreover, the mass production process of the sensor is simple and the cost is low, which is particularly suitable for large-...
