Description
TECHNICAL FIELD
[0001] The utility model relates to a blood scraping spoon for blood type detection experiment belongs to medical experimental apparatus technical field. BACKGROUND
[0002] Blood type detection is a classic experimental project in medical immunology teaching, including ABO blood type detection and Rh blood type detection. Its principle is direct agglutination reaction, and specific binding of blood group antigen and specific antibody appears obvious agglutination phenomenon under certain conditions in vitro. The experimental phenomenon is very typical, and it is closely related to the clinic. Students are interested and have high participation. In the traditional experimental operation, after taking the peripheral blood, the students need to scrape a drop of blood on one corner of the slide, put it into the double concave slide and mix with specific antibody, but nearly 40% of the students in each experimental class have too few blood cells in the double concave slide, which leads to false negative, so that the correct result cannot be observed.
[0003] The reasons mainly include the following aspects:
[0004] 1) When scraping blood, the peripheral blood squeezed from the blood collection site is not easy to scrape onto the slide because of the certain thickness of the slide;
[0005] 2) The peripheral blood on the slide is easy to stick to the edge of the slide, and the area is wide, so it is not possible to put all the scraped peripheral blood into the double concave slide and mix with the specific antibody, so that the amount of blood cells in the experiment is insufficient, and the experimental phenomenon cannot be observed.
[0006] When two drops of peripheral blood are scraped with a slide and mixed with anti-A antibody or anti-B antibody in the two concave surfaces of the double concave slide, different toothpicks are used to mix the liquid in the two concave surfaces in teaching. In order to prevent anti-A antibody and anti-B antibody from being confused, different toothpicks must be used to mix the liquid in each concave surface. Although it is repeatedly emphasized in the classroom, students often forget to change toothpicks when mixing with toothpicks, and draw wrong experimental conclusions. CONTENT OF THE UTILITY MODEL
[0007] In order to overcome the shortcomings of the prior art, the utility model provides a blood scraping spoon for blood type detection experiment. The blood scraping spoon can fully scrape the peripheral blood and ensure that the peripheral blood is put into the concave surface of the double concave slide and mixed with the antibody. The two antibodies can be effectively prevented from being confused in the mixing process, and the correctness of the result is ensured.
[0008] The utility model solves the technical problems by adopting the following technical scheme: a blood scraping spoon for blood type detection experiment, including stick body, spoon body a and spoon body b, the stick body is a long strip cylindrical body, one end of the stick body is fixed with a spoon body a, the other end of the stick body is fixed with a spoon body b, the spoon body a and the spoon body b are small spoon-shaped thin-walled edges and the same structure.
[0009] Further, the openings of the spoon body a and the spoon body b are consistent in orientation.
[0010] Further, the distal ends of the spoon body a and the spoon body b are linear.
[0011] Further, the rod body, the spoon body a and the spoon body b are of an integral structure.
[0012] Further, the length of the rod body is 7 cm, the diameter of the rod body is 3-4 mm, and the inner diameter of the spoon body a and the spoon body b is 4-5 mm.
[0013] Further, the rod body is divided into two equal parts, one part of the rod body is light blue and the other part of the rod body is light yellow.
[0014] Further, the rod body, the spoon body a and the spoon body b are made of straw regenerated degradable material.
[0015] The two spoon bodies of the utility model can fully scrape the peripheral blood, can guarantee that the peripheral blood is put into the concave surface of the double concave glass and mixed with the antibody, does not waste blood cells, guarantees that the appropriate red blood cells react with the antibody, and correct experimental results appear; through the differentiation of different colors, the two kinds of antibodies can be effectively guaranteed not to be confused in the mixing process of the liquid, and the correctness of the results is guaranteed.

[0021] For example, Figure 1As shown in FIG. 2, the scraping spoon for blood group detection experiment comprises a rod body 1, a spoon body a 2 and a spoon body b 3. The rod body 1 is a long strip-shaped cylinder. One end of the rod body 1 is fixed with the spoon body a 2, and the other end of the rod body 1 is fixed with the spoon body b 3. The rod body 1, the spoon body a 2 and the spoon body b 3 are of an integral structure and are made of straw regenerated degradable material. The spoon body a 2 and the spoon body b 3 are both small spoon-shaped and have the same structure. The spoon body a 2 and the spoon body b 3 are linear at the end away from the rod body 1. The openings of the spoon body a 2 and the spoon body b 3 are consistent. The length of the rod body 1 is 7 cm, the diameter of the rod body 1 is 3-4 mm, and the inner diameter of the spoon body a 2 and the spoon body b 3 is 4-5 mm. The rod body 1 is divided into two equal parts. One part of the rod body 1 and the spoon body a 2 are light blue, and the other part of the rod body 1 and the spoon body b 3 are light yellow.
[0022] The scraping spoon combines the functions of a slide and a toothpick. The scraping spoon is made of straw regenerated degradable environmental protection experimental material. In the use process, a double concave slide is prepared in advance. The double concave slide has two concave surfaces. Anti-A antibodies are added to one concave surface, and anti-B antibodies are added to the other concave surface. The spoon body a 2 and the spoon body b 3 can scrape the peripheral blood and place it in the anti-A antibodies and the anti-B antibodies, respectively. The spoon body a 2 and the spoon body b 3 are small spoon-shaped structures with thin edges. The spoon body a 2 and the spoon body b 3 are linear at the end away from the rod body 1. The linear edges can fully scrape the peripheral blood and ensure that the peripheral blood is placed in the concave surface of the double concave slide to mix with the antibodies. Blood cells are not wasted, and an appropriate amount of red blood cells is ensured to react with the antibodies to obtain correct experimental results.
[0023] The scraping spoon is divided into two equal parts and is made into different colors. One side is light blue, and the other side is light yellow. The colors are consistent with the colors of the anti-A antibodies and the anti-B antibodies. The light blue end is used to mix the liquid in the concave surface containing the same color anti-A antibodies, and the light yellow end is used to mix the liquid in the concave surface containing the same color anti-B antibodies. The two kinds of antibodies are not confused in the mixing process, and the correctness of the results is ensured.
