Problems solved by technology

At present, manufacturers mostly focus on electrochemical induction test strips for research, but the manufacturing process is relatively complicated and requires the cooperation of instruments to interpret the results, so the cost remains high
Another shortcoming is that the instrument needs to use electricity, which not only consumes energy, but also is not easy to popularize in countries or regions lacking resources.

Embodiment Construction

[0024] refer to Figure 1~2 , are respectively a perspective view and a longitudinal sectional view of a biomedical detection device in a preferred embodiment. The figure shows that a medical detection device mainly includes a hydrophilic layer 11, a hydrophobic layer 12, two test papers 13, 14, and a casing 10 for covering and holding the aforementioned components. The biomedical detection device of this embodiment is made in a strip shape as a whole.

[0025] The housing 10 is mainly composed of a transparent substrate 101 and a transparent cover 102 . The strip-shaped hydrophilic layer 11 and hydrophobic layer 12 made of cloth material are connected to each other, wherein the hydrophilic layer 11 includes an introduction portion 111 at the end, and the hydrophobic layer 12 is dug with two spaced apart hollow grooves 121,122. The aforementioned test papers 13, 14 are correspondingly accommodated in the two hollow grooves 121, 122 and extend and contact the hydrophilic laye...

Abstract

A biomedical diagnostic device includes a hydrophilic layer, hydrophobic layer, and at least one test pad. The hydrophilic layer includes an exposed introductory portion adapted to introduce a test fluid, and is stacked with the hydrophobic layer with multiple access holes. At least one test pad, each of which includes a distinguishing reaction medium, is disposed in the corresponding holes that extend to contact the hydrophilic layer. The relations within the device are as follows: hydrophilicity of any of the test pads>hydrophilicity of the hydrophilic layer>hydrophilicity of the hydrophobic layer.

Description

technical field [0001] The invention relates to a biomedical detection device, in particular to a biomedical detection device for one-time detection of multiple biological markers, which has the characteristics of extremely simplified structure and low manufacturing cost. Background technique [0002] Health has always been one of the most important issues in human life, especially with the progress of civilization and economic growth, many diseases of civilization have been born. The concept of disease prevention has long been accepted by the public, and early detection is one of the methods of disease prevention. Traditionally, to detect the occurrence of diseases at an early stage means that considerable manpower, material resources, and lengthy time are required, not to mention high amounts of money. Therefore, usually only large hospitals and other institutions can provide the above-mentioned detection services. [0003] Disease detection can be divided into invasive m...
