The objective of the present study was to determine the size of the bloodspots produced by the blood drops of different volume (5, 20, 40, and 80 mcl) falling down from different heights to enable the evaluation of the height of a suspended bloodstained object. The bloodspots of the blood drops of different volume (5, 20, 40, and 80 mcl) falling down from different heights were obtained under the experimental conditions. It was shown that the size of the bloodspots increases with the increasing height of fall: the greater the height the larger is the diameter of the bloodspots. Given that the drop volume is known, the size of the bloodspots can be used to determine the height of the suspended bloodstained object. In the practical work of the forensic medical expert, the blood drop volume is as a rule unknown, therefore the height of their fall can be roughly determined based on the morphological features of the bloodspots.
本研究的目的是确定不同体积(5、20、40和80微升)的血滴从不同高度落下所产生的血斑大小,以便评估悬挂的带血物体的高度。在实验条件下获取了不同体积(5、20、40和80微升)的血滴从不同高度落下形成的血斑。结果表明,血斑大小随下落高度的增加而增大:下落高度越高,血斑直径越大。已知血滴体积时,血斑大小可用于确定悬挂的带血物体的高度。在法医专家的实际工作中,血滴体积通常是未知的,因此可根据血斑的形态特征大致确定其下落高度。
