Description
Technical field
The utility model 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.
Utility model content
The purpose of the utility model is to provide a kind of two-sided hydrophilic films, can greatly improve the blood of blood sugar test paper hydrophilic film
Diffusion, in favor of further increasing the detection accuracy of blood glucose target.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of two-sided hydrophilic film, including substrate are coated with upper layer hydrophilic film in the upper surface of substrate, in the lower surface of substrate
It is coated with lower layer's hydrophilic film, upper layer PE film is compounded in the upper layer hydrophilic film, under being compounded in lower layer's hydrophilic film
Layer PE 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 utility model are: the utility model changes the prior art in substrate single side
It is coated with the structure of hydrophilic film, is coated with hydrophilic film in the upper and lower faces of substrate for the first time, this structure can be by blood sample from upper and lower
Two sides diffuses to detection zone, substantially increases the blood diffusion of blood sugar test paper hydrophilic film, to improve blood diffusion
Reliability and validity are 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.The utility model
Two-sided hydrophilic film, after substrate upper surface completes coating and compound PE film, in substrate lower surface, it is dry to enter drying tunnel for coating hydrophilic film
When dry, 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 hydrophilic coating solvent of the utility model spirit solvent easily dry using low temperature, this makes it possible to dry using cold drying
It is dry, avoid the destruction to PE film.
