Description
Technical field
The present invention relates to a kind of two-sided hydrophilic films.
Background technique
In the detection of blood glucose quick diagnosis, blood sugar test paper has been widely used.In blood sugar test paper, detection accuracy is influenced
Other than oxidoreducing enzyme, conducting medium, there are also be exactly hydrophilic film.When tested blood sample drop is on blood sugar test paper, hydrophilic film energy
It is enough that drop of blood is quickly spread to and sucked electrode working zone, to ensure the progress of blood sugar test.
It, can only in the case where oxidoreducing enzyme, conducting medium have determined in order to improve the detection accuracy of blood sugar test paper
Improve the diffusion of hydrophilic film.The performance for how improving blood sugar test paper hydrophilic film, puts in face of those skilled in the art
One important topic.
Summary of the invention
The object of the present invention is to provide a kind of two-sided hydrophilic films, can greatly improve the blood diffusion of blood sugar test paper hydrophilic film
Performance, in favor of further increasing the detection accuracy of blood glucose target.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of two-sided hydrophilic film, including substrate are coated with upper layer hydrophilic film in the upper surface of substrate, are coated in the lower surface of substrate
There is lower layer's hydrophilic film, upper layer PE film is compounded in the upper layer hydrophilic film, is compounded with lower layer PE in lower layer's hydrophilic film
Film.
The upper and lower layer hydrophilic film is to be dissolved in ethanol solution by fatty alcohol polyoxyethylene ether to be coated on the substrate table
The film formed behind face through low temperature drying.
The substrate is made of PET material.
Compared with prior art the beneficial effects of the present invention are: the present invention to change the prior art hydrophilic in substrate one side coating
The structure of film is coated with hydrophilic film in the upper and lower faces of substrate for the first time, and this structure can spread blood sample from upper and lower surface
To detection zone, substantially increase the blood diffusion of blood sugar test paper hydrophilic film, thus improve blood diffusion reliability and
Validity is conducive to the detection accuracy for improving blood glucose target.
Existing blood sugar test paper is a surface (i.e. single side) the coating hydrophilic substance in substrate, passes through and be coated with drying tunnel
Dry, hydrophilic substance adheres to substrate surface and constitutes hydrophilic film, then the compound PE film in hydrophilic film.Of the invention is two-sided
Hydrophilic film, after substrate upper surface completes coating and compound PE film, when in substrate lower surface, coating hydrophilic film enters drying tunnel drying,
Because drying tunnel drying temperature is higher, it can deform, blister, delamination after the PE film of upper surface is heated, in order to solve this problem, the present invention
Hydrophilic coating solvent using the easily dry spirit solvent of low temperature, this makes it possible to dry using cold drying, avoid pair
The destruction of PE film.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram for manufacturing coating system used in the two-sided hydrophilic film of Fig. 1.
Specific embodiment
In order to be more clear technical solution of the present invention, below in conjunction with attached Fig. 1 and 2, the present invention is described in detail.
It should be understood that specific embodiment described in this specification is not intended to limit just for the sake of explaining the present invention
Protection scope of the present invention.
