Problems solved by technology

[0002] At present, the method used to detect hemoglobin content in the process of voluntary blood donation is the copper sulfate method. This method is a qualitative method with low accuracy, and the copper sulfate solution is not easy to carry and store, especially in voluntary blood donation. When used on the blood collection vehicle, it brings a lot of inconvenience to the staff
In summary, the copper sulfate method is not suitable for the detection of hemoglobin during voluntary blood donation

Embodiment Construction

[0010] As can be seen from the figure, the present invention includes a test paper strip 7 and a standard color comparison card 2, the test paper strip 7 is placed in a transparent plastic bag 6, and the transparent plastic bag 6 and the standard color comparison card 2 are pasted on the left side and the left side of the folding page 1 respectively. Right. The standard color card 3 is divided into two red areas of different shades, a zone 3 and b zone 4. The hemoglobin content represented by a zone 3 is 110g / L, and the hemoglobin content represented by b zone 4 is 120g / L. There is a reading hole 5 in the center of the area a 3 and the area b 4 . Drop the blood on each test paper strip 7 for about 30 seconds, and compare it with the color on the standard color card 2 through the reading hole 5: if the color of a female is the same as that of area a 3 or darker than that of area a 3 , that is, without anemia, you can participate in voluntary blood donation; if the color is lig...

Abstract

The test card includes test scrip and standard color grade card. Test scrips are put in transparent plastic bag in sequence. The bag and color grade card are pasted on left and right of folding respectively. There are two red areas a and b in different dark and light on the color grade card. The a area is for female, whose normal value of haemoglobin is 110g / L, and b area is for male, whose normal value of haemoglobin is 120g / L. an interpretation hole is located in center of a and b area respectively. Blood is dropped to a piece of test scrip. After about 30 seconds, spot of sampled blood is compared with color in color grade card through the hole. Based on result, determing whether a blood donor is qualified is made. Features of the test card are simple design, easy of carrying, fast and reliable testing.

Description

technical field [0001] The invention relates to a voluntary blood donation hemoglobin test card which can detect the content of hemoglobin in human blood, especially the voluntary blood donation hemoglobin test card which can quickly diagnose whether the voluntary blood donor has anemia during the voluntary blood donation process. Background technique [0002] At present, the method used to detect hemoglobin content in the process of voluntary blood donation is the copper sulfate method. This method is a qualitative method with low accuracy, and the copper sulfate solution is not easy to carry and store, especially in voluntary blood donation. When used on the blood collection vehicle, it brings a lot of inconvenience to the staff. In summary, the copper sulfate method is not suitable for the detection of hemoglobin during voluntary blood donation. Contents of the invention [0003] The purpose of the present invention is to provide a fast, reliable and accurate screening...
