Abstract

The purpose of the study is a theoretical analysis of the available types of contact traces of blood and the establishment of their occurrence at the objects of medical and forensic examinations. Contact marks are formed as a result of the mechanical interaction of two objects, one of which is stained with blood. The literature data allow us to distinguish several types of contact traces of blood: impressions, smears, smearing, «voids», traces in the form of changes in the existing stain from wiping, washing, traces-artifacts from insects. Each type has a mechanism of formation and characteristic features. We analyzed 107 archival medical and forensic examinations. In the examinations in which the material situation of the scene of the incident (5 or more objects) is maximally represented, contact traces were present in 76% of the examinations, which indicates a high occurrence. The following types of contact traces of blood were the most common: smears (29% of all examinations), smearing (22.4%) and «voids» (10.3%). Other types of contact traces were less common.

[在医疗和法医检查期间发现接触血的痕迹]。

这项研究的目的是对现有的血液接触痕迹类型进行理论分析，并确定其在医学和法医检查对象上的发生情况。接触痕迹是由于两个物体的机械相互作用而形成的，其中一个物体沾有血迹。文献数据使我们能够区分几种类型的血液接触痕迹:印痕、污迹、污迹、“空洞”、擦拭、洗涤造成的现有污渍变化形式的痕迹、昆虫留下的痕迹。每种类型都有其形成机理和特征。我们分析了107份医学和法医鉴定档案。在最大限度地反映事件现场物质情况(5个或更多物体)的检查中，76%的检查中存在接触痕迹，这表明发生率很高。以下类型的血液接触痕迹最常见:涂片(占所有检查的29%)、涂片(22.4%)和“空洞”(10.3%)。其他类型的接触痕迹不太常见。
