Description

A kind of portable bloodstain extraction collection packet

Technical field

The utility model belongs to science and technology concerning criminal matters field, and in particular to a kind of portable bloodstain extraction collection packet.

Background technique

Bloodstain is important one of the evidence in scene.Bloodstain not only has biological characteristics, but also has ichnology characteristic, has simultaneously There is the characteristics of objectivity, stability, popularity and practicability, there are other traces, object in the investigation and hearing process of case Demonstrate,prove irreplaceable important function.Bloodstain is investigated on the spot at the scene and has unique effect in analysis simultaneously: sentencing first is that can be used as The important means of disconnected death pathways；Second is that can be used as whether the scene of determination is original scene foundation；Third is that can be used as scene The main method of reconstruction；Fourth is that can be used as determining body source reliable basis；Fifth is that can be used as identification or exclude suspect Effective ways.Solve a case practice have shown that: gone point with the materialist dialectics and Scientific Methodology and various advanced technological means Analysis interpret bloodstain included in all Crime Informations be detection one important link of homicide case part, or even as solve a case key and Breach.

Bloodstain objectively reflects the process that case occurs, reliably usually with its live trace, feature and distributional pattern Criminal offence is recorded, provides necessary clue for investigation.Also it can be carried out with specific sample same by carrying out DNA chemical examination to it One assert, the police is helped to determine case property, and positive or negative suspicion object.Bloodstain form is examined and DNA extraction is criminal One of the important component of science and technology, be during criminal case detection the most basis, the most commonly used technological means it One.The basic task that bloodstain is examined is analysis bloodstain form, collects bloodstain sample, and scene of a crime bloodstain is examined in analysis, to be Cracking of cases provides evidence.Wherein, most basic work is exactly that the extraction to bloodstain is collected.

It is maximized to realize that bloodstain collects storage effect, for the bloodstain material evidence under different condition and state, we will be adopted Take different extraction collection methods.Live bloodstain may exist with the state of liquid blood, moist bloodstain or dry blood stain.Therefore Bloodstain is extracted at scene, should also use suitable method.

In the undetermined homicide case of certain suspects, by the inspection for staying biological sample especially bloodstain to scene It surveys, the effect for surmounting traditional traces such as fingerprint, shoes print can be played in terms of the preliminary identification or exclusion of suspect, thus it is more next More by the attention of appraiser.

Sorry not have special bloodstain to extract collection packet at present, bloodstain extraction is intended only as in site inspection traditional material evidence A part of extraction.But bloodstain is because of its special biological property, if extracted as common material evidence collect be highly contaminating or Failure, causes qualification result mistake occur, it is possible to misleading investigation direction, misses and most preferably solves a case opportunity.

In summary, it is necessary to invent a kind of portable bloodstain and extract and collect packet to solve the above problems.

Utility model content
