Description

Artificial blood for generating expected bloodstains and method of manufacturing the same Embodiments of the present invention relate to artificial blood for reproducing exhaled bloodstains and a method for manufacturing the same. In criminal cases, bloodstain pattern analysis plays an important role in estimating and reconstructing the actions of the victim and the perpetrator at the time of the incident. The forms of bloodstains found at crime scenes are very diverse, and their forms vary depending on the act that caused their formation, the site of origin, and the constituent materials of the bloodstain. Bloodstains are classified and named based on their forms. Human blood, animal blood, or artificial blood is used when bloodstain reproduction experiments are required during bloodstain pattern analysis. However, this may lead to issues regarding user aversion and safety. In particular, when using human or animal blood, there are many limitations in procuring the necessary quantities for the experiment, as well as safety and ethical issues. Currently, most artificial blood sold for forensic experimental purposes is imported from abroad. Artificial blood manufactured overseas presents problems such as high costs, non-disclosure of product composition, and differences in physical properties compared to human blood. Research on artificial blood is continuously being conducted to address the aforementioned problems. In particular, when reproducing exhaled bloodstains, the experimenter must hold artificial blood in their mouth and then spit it out, so there is a problem of reducing the aversion to artificial blood and ensuring safety. FIG. 1 is artificial blood for reproducing exhaled bloodstains according to an embodiment of the present invention. FIG. 2 is a flowchart illustrating a method for manufacturing artificial blood for reproducing exhaled bloodstains according to one embodiment of the present invention. Figure 3 is a drop bloodstain generating device used in the experiment of the present invention. Figure 4 is a photograph showing the shape of a bloodstain at different impact angles generated by artificial blood for reproducing exhaled bloodstains according to an embodiment of the present invention. FIG. 5 is a graph comparing data on the ratio of the short axis to the long axis of an embodiment of the present invention, human blood, and comparative examples 1 and 2. Figure 6 is a diagram showing the collision between a blood drop and a surface. FIG. 7 is a graph comparing data on the estimated collision angle calculation results of the embodiment of the present invention, human blood, and comparative examples 1 and 2. It should be noted that in the following description, only the parts necessary for understanding the embodiments of the present invention are described, and the description of other parts will be omitted to the extent that it does not detract from the gist of the present invention. The terms and words used in the specification and claims described below should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention. Accordingly, the embodiments described in this specification and the configurations illustrated in the drawings are merely preferred embodiments of the invention and do not represent all aspects of the technical spirit of the invention; therefore, it should be understood that various equivalents and modifications capable of replacing them may exist at the time of filing this application. Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. In this specification, 'expectorated blood spatter' refers to blood that is expelled from the respiratory tract due to bleeding occurring in the victim's respiratory tract. To reproduce 'expectorated blood spatter,' the experiment may be performed by having the experimenter hold artificial blood in their mouth and then forcefully expel it. FIG. 1 is artificial blood for reproducing exhaled bloodstains according to an embodiment of the present invention. FIG. 2 is a flowchart showing a method for manufacturing artificial blood for reproducing exhaled bloodstains according to an embodiment of the present invention. Artificial blood for reproducing exhaled bloodstains according to one embodiment of the present invention may include maple syrup, water, and food coloring. Specifically, a method for manufacturing artificial blood for reproducing exhaled bloodstains according to one embodiment of the present invention is as follows. Step 100 is the step of making a maple syrup solution by mixing maple syrup and water. Maple syrup is a sweetener made from the sap of maple trees. Maple syrup contains water, sucrose, fructose, gluc
