Various bloodstains can be observed at the crime scene of bloodshed such as murder. Among them, projected bloodstains are bloodstains that can be caused by a large amount of blood projected due to damage to the arteries, which are major blood vessels, and can be a key basis for behavior reconstruction in crime scene. These bloodstain can be created due to partial or complete amputation of the artery or venous blood vessels, and their shape and distribution can be formed differently depending on the heartbeat, diameter of the blood vessels, blood pressure, gravity, etc. Therefore, a bloodstain pattern analysis(BPA) experiment is needed, and the development of a device to reproduce the bloodstain is necessary. In this study, we designed device can reproduce projected bloodstain by copying human heart and blood vessel. We used pump, power-supply, silicone hose, potentiometer, manometer to design the device. Experiment was carried out that reproducing the projected bloodstain, depending on the size of blood vessels. The projected bloodstains were similar to the bloodstains that were reported. The device can reproduce similar projected bloodstains observed in crime scene. So, we purpose the device for reproducing projected bloodstain for crime scene reconstruction. Though, there is a difference between the actual heart and blood vessels, so it is believed that follow-up studies are needed to supplement them.
