Description
Technical field
The present invention relates to science and technology concerning criminal matters department of a kind of public security organ surveys at the scene for all kinds of criminal case crime scenesThe aobvious device of essential a kind of automatic rotary brush that uses special powder to manifest fingerprint in looking into.
Background technology
In Exploration Practice, most all kinds of criminal case crime scenes all be unable to do without fingerprint significant powder brush at the scene. DecadesCome, fingerprint significant powder brush be always the most effectively, the fingerprint manifestation means that the most practical and utilization rate is the highest.
Fingerprint significant powder brush is generally used for the invisible fingerprints of sweat of comparatively fresh, and its principle is for different smooth objects (wooden tableFace, glass and iron surface etc.) different characteristics, utilize the fresh sweat of human body to there is electronegativity and stickiness, powder is had to oneThe feature of fixed physics affinity, selects corresponding powder to brush aobvious, colourless fingerprint is become to the coloured fingerprint that adds layer.
Current, in the site inspection case that each police equipment supplier produces, generally include magnetic powder, silver powder, bronze,Magnetic is whitewashed and hairbrush.
Use traditionally the method for operating of fingerprint significant powder brush to be: site inspection personnel first open powder box lid, use subsequentlyMagnetic is whitewashed (or hairbrush) absorption (or dipping) part powder, and makes powder be scattered in equably the object that fingerprint may retainUpper, and then whitewash (or hairbrush) by magnetic and gently brush specific smooth object, colourless fingerprint just becomes coloured lines of the hand.
For a long time, fingerprint significant powder brush technology rests on the manual stage always, and jargon is commonly called as " one brush brush all over the world ".Fingerprint significant powder brush extract the present situation of means cannot comply with increasingly serious social security new situations an urgent demand.
The powder that traditional-handwork fingerprint significant powder brush is general used comprises two classes, is magnetic powder and gold (silver) powder.
(1) magnetic powder (thinner magnetic metal powder), Particle Phase is thick to bronze or silver powder, is applicable to metope ceramics and cabinetThe smooth objects such as door, shortcoming in Exploration Practice is as follows at the scene for it:
1, each site inspection personnel's individual professional qualities residual error is uneven, and this directly affects the effect of fingerprint manifestation, thisA bit in the time that long-time or large-area brush is aobvious, performance is particularly outstanding. Keep for a long time good working order to depend on individual waterThe factors such as gentle sense of responsibility height.
2,, for irony object or magnetic object, because magnetic powder and object attract each other, magnetic is whitewashed aobvious powerWeight be difficult to hold, unless you give your whole attention to it, too much magnetic powder will be easy to be adsorbed on object, and these too much magnetic powderBut be difficult to effectively be removed, finally make to manifest effect and destroyed.
3, for objects such as on a large scale vertical metope or cabinet doors, site inspection personnel brush aobvious need to maintenance for a long timeTorticollis, the given pose such as bend over, physical demands is huge, can be easy to cause for a long time the disease such as lumbar vertebrae and cervical vertebra in the past.
4,, due to the reason such as manual operation or gravity, the each brush of expensive magnetic powder is aobvious all has coming off in various degree,The long-term waste in the past causing is very serious.
5, in routine duties, many times, site inspection personnel can be the magnetic of being infected with the impurity such as a little earthPowder is recovered in powder box and reuses, and in the past for a long time, the adsorptivity of magnetic powder will reduce gradually, finally caused work afterwardsThe fingerprint that in work, this manifests is not showed to come by brush, has omitted opportunity of combat.
(2), silver powder (superfine, extremely light heavy metal powder) or bronze (ultra-fine, ultralight heavy metal powder) brush are aobvious:Grain is little, and strong adhesion is applicable to the smooth object such as glass, and shortcoming in Exploration Practice is as follows at the scene for it:
1, bronze or silver powder, due to strong adhesion, are difficult to control the thickness of brush dust in brush is aobvious, and brush dust has lacked and manifested effectBad, brush dust is many can execution. Fingerprint manifestation effect is entirely with the qualification of site inspection personnel individual skill.
2,, for objects such as large-scale glass doors, site inspection personnel brush to show and need to keep for a long time torticollis, curvedThe given pose such as waist, physical demands is huge, easily causes for a long time the disease such as lumbar vertebrae and cervical vertebra in the past.
3, because bronze and silver powder are thin and light heavy metal powder, brush around object, can form when aobvious huge" dust cloud ", it can be floating for a long time in air. If swim in airborne heavy metal dusts by site inspection personnelSuck lung with near the masses, will be difficult to be excreted by metabolism. Medical mask in the market all cannot be effectiveFiltered image bronze or silver powder trickle dust like this like this. In criminal case crime scene today occurred frequently, site inspection personnel constantlyCarve and be all exposed in extraordinary dust atmosphere, emitting the risk of suffering from " pneumoconiosis " such occupational disease to carry out work.
4, many times, after the aobvious EO of brush, on site inspection personnel's Head And Face and clothes, often can be infected with largeAmount is difficult to bronze powder or the silver powder powder removed. So just cause secondary pollution, be harmful to health.
5,, due to the reason such as manual operation or wind-force, the each brush of expensive bronze or silver powder is aobvious all has in various degree de-Fall, thereby the waste causing is very serious.
6, traditional hairbrush must be constantly manually " dipping in powder " could brush complete object, show large-area object is brushedTime, its operating efficiency is very low.
7,, because bronze and silver powder are harmful to health, in reconnoitring at the scene, a lot of site inspection personnel are accustomed to the first-selected magnetic that usesProperty powder brush aobvious, can use magnetic powder just without bronze or silver powder, but for some object, bronze or silver powder are brushed aobvious effectFruit may be better. In the past for a long time, in site inspection, the quality of fingerprint extraction will be affected.
