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 utility model includes a test paper strip 2, a standard color comparison card 3 and a hard board 1. There is a groove 7 at the bottom of the hard board, and the standard color comparison card 3 is placed in the groove 7, and the test paper strip 2 is sequentially Arranged on the hard board 1 plane. The upper plane of the hard board is grid-like, with eight grids in the horizontal direction and twelve grids in the vertical direction. The test paper strips 2 are arranged in each small grid of the hard board 1 in sequence. Each red area 4 represents a corresponding amount of hemoglobin, and each red area 4 has a reading hole 5 in the center. Drop the blood on each piece of test paper 2 for about 30 seconds, and compare it with the color on the standard color card through the reading hole: if the color of a female is the same as that of area a or darker than that of area a, then there is no anemia , you can participate in voluntary blood...

Abstract

The device includes testing scrip, standard color grade card and hard plate. A flute is on bottom part of the plate. The color grade card is put in the flute. Grids including 8 grids in lateral and 12 grids in vertical and testing scrip is in each grid. There are two red areas in different dark and light on the color grade card. Different red color represents different amount of haemoglobin. An interpretation hole is located in center areas 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, determining whether a blood donor is qualified is made. Features of the test device are simple design, easy of carrying, fast and reliable testing.

Description

technical field [0001] The utility model relates to a rapid test device for blood donation hemoglobin which can detect the content of hemoglobin in human blood, in particular to a fast test device for blood donation hemoglobin which can quickly diagnose whether there is anemia in the 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. Utility model content [0003] The purpose of the utility model is to provide a hemoglobin rapid detection device that can quickly, reliably and accu...
