Problems solved by technology

However, the existing microfluidic chip is only used to carry test strips, and it does not have a power system. Therefore, when using a microfluidic chip for urine analysis, an external power device is required to make the urine flow in the microfluidic chip. flow, thereby increasing the size and cost of the analytical device

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] figure 1 A side view of a detection card provided for an embodiment of the present invention, such as figure 1 As shown, the test card includes a substrate 1 and an encapsulation layer 2, and also includes a test paper carried by the substrate 1, wherein the encapsulation layer 2 is used to encapsulate the substrate 1 and the test paper carried by the substrate 1 to isolate the test paper from the atmosphere. The substrate 1 includ...

Abstract

The invention discloses a body fluid analyzing method. The body fluid analyzing method is used for omitting an additionally-arranged power device and applied to a detecting card. The detecting card comprises a base plate, test paper borne by the base plate, and a sealing layer. A sample feeding area of the base plate communicates with the sample inlet side of a test paper area directly or indirectly, and a gas outlet area communicates with the sample outlet side the test paper area directly or indirectly. The body fluid analyzing method comprises the steps that the sealing layer is treated, and a sample inlet and a gas outlet both communicating with the atmosphere are formed; the sample inlet is located in the upper portion of the sample feeding area, and the gas outlet is located in the upper portion of the gas outlet area of the base plate; to-be-detected fluid is injected into the sample feeding area of the base plate through the sample inlet; the to-be-detected fluid is guided to the test paper in the test paper area of the base plate; and after the preset reacting time, the test paper in the test paper area is detected. Balance between the interior of the detecting card and the external atmosphere can be achieved through the sample inlet located in the upper portion of the sample feeding area and the gas outlet located in the upper portion of the gas outlet area, blockingfor flowing of the to-be-detected fluid by gas is avoided, and thus test paper sample adding is achieved.

Description

technical field [0001] The invention relates to the field of medical detection, in particular to a body fluid analysis method. Background technique [0002] Body fluid analysis, such as urinalysis, blood analysis, etc., is an important test method in clinical testing, especially urinalysis, which is often used in hospitals and various medical institutions. The basic methods of urine analysis can be roughly divided into the following two types according to the different types of test paper: the first one, according to the phenomenon of discoloration due to the chemical reaction between the test paper block and the components in the urine, using light to irradiate the test paper block immersed in urine, And detect the color and intensity information of the reflected light, so as to calculate the concentration of chemical components in the urine; second, the antigen in the solution crawls along with the solution along the test paper to the reaction area on the test paper. For ...
