Embodiment Construction

[0015] Below in conjunction with specific embodiment further illustrate the present invention.

[0016] see figure 1 and figure 2 , a kind of blood glucose test paper that the embodiment of the present invention provides, comprises substrate 10, the working electrode 20 that is formed on the substrate, reference electrode 30, counter electrode 40 (ie return electrode), and described working electrode 20, reference A circuit 50 in which the electrode 30 and the counter electrode 40 are connected.

[0017] A composite material layer 60 is formed on the working electrode for reacting with the blood sample. The composite material layer 60 includes: a polymer film, and inorganic nanoparticles adhered and dispersed in the polymer film.

[0018] Generally speaking, there is no specific requirement for the thickness of the polymer film, and it is preferably 1-300 microns. Specifically, the polymer film may be perfluorosulfonic acid resin, polytetrafluoroethylene, polyvinylidene f...

Abstract

The invention belongs to the field of blood sugar test by using the electrode method. To overcome the technical problems that existing blood sugar testing paper is expensive, has high requirements for a preservation condition and a short period of validity, can only be used once, etc., the invention provides blood sugar testing paper which comprises a substrate, a working electrode and a counter electrode formed on the substrate, a circuit connected with the working electrode and the counter electrode and a composite material layer formed on the working electrode for reaction with a blood sample, wherein, the composite material layer comprises a polymer membrane and inorganic nanometer particles dispersed in and adhering to the polymer membrane.

Description

【Technical field】 [0001] The invention relates to a test paper for blood glucose testing, which belongs to the field of electrode method blood glucose testing. 【Background technique】 [0002] There are about 50 million diabetics in my country, accounting for a quarter of the total number of diabetics in the world, and the number is still increasing by 1.2 million every year. As an indispensable instrument for diabetes monitoring, rapid blood glucose meter has become popular among the majority of diabetic patients. Commercially available rapid blood glucose meters are divided into two categories: photochemical method and electrode method according to the working principle. Among them, the electrode method blood glucose meter needs less blood volume, the test result is fast, and it is very easy to use. However, due to the inadequacy of the test strips for commercially available blood glucose meters, they have high requirements for the test environment. Many patients, and eve...
