Description
Technical field
The present invention relates to science and technology concerning criminal matters department of a kind of Public Security Organs aobvious device of essential a kind of automatic rotary brush that uses special powder to manifest fingerprint in the reconnaissance at criminal scene for all kinds of criminal case crime scenes.
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.In decades, 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, its principle is the different characteristics for different smooth objects (wooden table tops, glass and iron surface etc.), utilize the fresh perspiration of human body to there is electronegativity and stickiness, the feature that powder is had to certain physics affinity, select corresponding powder to brush aobvious, colourless fingerprint is become to the coloured fingerprint that adds layer.
Current, in the reconnaissance at criminal scene case that each police equipment supplier produces, generally include magnetic powder, argentum powder, bronze, magnetic is whitewashed and hairbrush.
Use traditionally the operational approach of fingerprint significant powder brush to be: reconnaissance at criminal scene personnel first open powder box lid, by magnetic, whitewash (or hairbrush) absorption (or dipping) part powder subsequently, and powder is scattered on the object that fingerprint may retain equably, and then by magnetic, whitewash (or hairbrush) 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 ".The present situation that fingerprint significant powder brush extracts 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 argentum powder, is applicable to the smooth objects such as metope ceramics and cabinet door, and shortcoming in Exploration Practice is as follows at the scene for it:
1, each reconnaissance at criminal scene personnel's individual professional qualities residual error is uneven, and this directly affects the effect of fingerprint manifestation, and this point performance when long-time or large-area brush is aobvious is particularly outstanding.Keep for a long time good working order to depend on the factors such as individual level and responsibility height.
2, for irony object or magnetic object, because magnetic powder and object attract each other, the weight that magnetic is whitewashed aobvious power is 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 powder are difficult to effectively be removed, finally make to manifest effect and destroyed.
3, for objects such as on a large scale vertically metope or cabinet doors, reconnaissance at criminal scene personnel brushs and show the given pose such as need to keep for a long time torticollis, bend over, and physical demands is huge, can be easy to cause for a long time the diseases such as lumbar vertebra and cervical vertebra in the past.
4, due to reasons such as manual operation or gravity, the each brush of expensive magnetic powder is aobvious all has coming off in various degree, and the waste in the past causing is for a long time very serious.
5, in routine duties, many times, reconnaissance at criminal scene personnel can be recovered to the magnetic powder of being infected with the impurity such as a little earth in powder box and reuse, in the past for a long time, the adsorptivity of magnetic powder will reduce gradually, finally cause this fingerprint manifesting in work afterwards by brush, not showed to come, omitted opportunity of combat.
(2), argentum powder (superfine, extremely light heavy metal powder) or bronze (ultra-fine, ultralight heavy metal powder) brush is aobvious: granule is little, and strong adhesion is applicable to the smooth objects such as glass, and shortcoming in Exploration Practice is as follows at the scene for it:
1, bronze or argentum powder is due to strong adhesion, is difficult to control the thickness of brush dust in brush is aobvious, and brush dust has lacked that to manifest effect bad, and brush dust is many can execution.Fingerprint manifestation effect is entirely with the proficiency level of reconnaissance at criminal scene personnel individual skill.
2, for objects such as large-scale glass doors, the given pose such as reconnaissance at criminal scene personnel brush aobvious need to keep torticollis for a long time, bend over, physical demands is huge, easily causes for a long time the diseases such as lumbar vertebra and cervical vertebra in the past.
3, because bronze and argentum powder are thin and light heavy metal powder, can form huge " dust cloud " around brushing object when aobvious, it can be floating for a long time in air.If swim in airborne heavy metal dusts, by reconnaissance at criminal scene personnel and near the masses, sucked pulmonary, will be difficult to be excreted by metabolism.Medical mask is in the market effective filtered image bronze or argentum powder trickle dust like this so all.In criminal case crime scene today occurred frequently, reconnaissance at criminal scene personnel are at every moment exposed in extraordinary dust atmosphere, emitting suffer from " pneumoconiosis " like this risk of occupation disease carry out work.
4, many times, after the aobvious EO of brush, on reconnaissance at criminal scene personnel's Head And Face and clothes, often can be infected with the bronze powder or the argentum powder powder that are difficult in a large number removing.So just caused secondary pollution, be harmful to health.
5, due to reasons such as manual operation or wind-force, the each brush of expensive bronze or argentum powder is aobvious all has coming off in various degree, thereby the waste causing is very serious.
6, traditional hairbrush must be constantly manually " dipping in powder " could brush complete object, large-area object is being brushed while showing, its work efficiency is very low.
7, because bronze and argentum powder are harmful to health, in reconnoitring at the scene, a lot of reconnaissance at criminal scene personnel are accustomed to that first-selected to use magnetic powder brush aobvious, can use magnetic powder just without bronze or argentum powder, yet for some object, bronze or argentum powder are brushed aobvious effect may be better.In the past for a long time, in reconnaissance at criminal scene, the quality of fingerprint extraction will be affected.
