Abstract
The invention discloses a spraying device for developing biological trace evidences. The spraying device comprises a container, wherein an opening and an accommodation space communicated with the opening are formed in the container; a trace evidence developing solution for developing a biological trace evidence is accommodated inside the accommodation space; a sprayer is arranged inside the opening; the sprayer comprises a piezoelectric oscillation element contacting the trace evidence developing solution; the piezoelectric oscillation element is oscillated at a high frequency to form the trace evidence developing solution into multiple liquid particles which can be discharged outside the container. Under the action of the piezoelectric oscillation element, the liquid particles are formed from the trace evidence developing solution and can be directly sprayed to the biological trace evidence through the opening, the trace evidence developing solution can have oxidation reduction reaction with components of the biological trace evidence directly, then colored products can be generated, and thus the biological trace evidence can be revealed and seen.
Description
Technical field
The present invention is to relate to a kind of device for biological mark card development, particularly relates to a kind of for biological mark card
The sprayer unit of development.
Background technology
With development and the progress of science and technology and instrument, biological mark card has been widely used in criminal identification neck
In territory, becoming one of material evidence being adopted, it is exclusive that biological mark card refers to individual institute, can be used to distinguish between individuality
Difference, as the biocompatibility characteristics of individual status identification, such as fingerprint, blood, hair and body fluid etc., its
In again with fingerprint be most common and be usually used in criminal identification biological mark card.
Illustrate with fingerprint, which is human finger's end and refer to by concavo-convex the formed lines of skin on abdomen, its
It is characterized as that everyone fingerprint all differs, there is unique characteristic, be therefore often applied to status and distinguish
The purposes known, such as individual's login system, entry and exit identity identification, seal replacement, Criminal Investigation etc..
When finger touches article, generally described fingerprint can be left on described article, in described fingerprint also
Containing by the sweat being positioned at secreted by the sweat gland of skin, its composition major part is moisture, separately still have protein,
Organic compound, lipid and urea, this is also to use described fingerprint as investigation instrument in Criminal Investigation
The reason, but the described fingerprint being so printed on mutually on described article is difficult to be seen, therefore multiple make described
Fingerprint manifestation and the method that is seen just are arisen at the historic moment, and the method for most common of which has powder development method, sootiness
Method and peaceful hydrin method.
In the middle of relatively early used for powder development method, its principle is for utilizing brush to flutter brush in one silver powder or magnetic
To the article being attached with described fingerprint, described silver powder or magnetic can be adsorbed on described moisture by electrostatic force
To present the complexion of described fingerprint, make described fingerprint can be revealed and see, but silver powder or magnetic are being flutterred
During brush extremely described fingerprint, described brush directly can touch with described fingerprint, and has the described fingerprint of destruction
Doubt, and described moisture can be exposed to that time of air is longer with described fingerprint and content is fewer, cause
Described silver powder or magnetic are difficult to be adsorbed to described fingerprint, and the complexion making described fingerprint is unclear and is difficult to identification.
Because of the problems referred to above, just developing thereafter need not be with the fumigation that described fingerprint directly touches and Ninghai moral
Lin Fa.The principle of fumigation is, is positioned over one in a closed container with the determinand of described fingerprint, connects
The solution heating containing cyanoacrylate by become gaseous state and riddle described closed container, make described
Cyanoacrylate carries out a polymerization with the described protein on described fingerprint or described lipid and is formed
White product, makes described fingerprint can be revealed and see.As TaiWan, China new patent announces M348634
Number " automatic fumigating device ", it discloses a kind of automatic fumigating device, first by a sootiness unit by described
Cyanoacrylate becomes gas and riddles in confined space, then pumps unit by one and will carry out described polymerization
Waste gas after effect is pumped and is carried out filtering to reduce its toxicity to a filter element.But because of described cyanoacrylate
Acid esters has toxicity, although can be reduced toxicity by filtering, must avoid using, and because of described closed container
Size is limited, therefore also limit the size of described determinand, makes the method cannot be used in large-scale determinand.
It as peaceful hydrin method, is described determinand to be soaked in a mark card developing solution, in the method
Described mark card developing solution is particularly with the composition of a peaceful hydrin (Ninhydrin), because peaceful hydrin can be with
Described protein in described fingerprint carries out reacting and generating color products, make described fingerprint to be revealed and
See.Described peaceful hydrin is the material not having toxicity, and can use open containers when soaking, therefore compared with fumigation
It is more preferably suitable for using.
In summary, above-mentioned existing development biological mark card technology, has and is easily destroyed biological mark card, to be measured
Thing is size-constrained and equipment such as cannot carry at the problem.
Content of the invention
The main object of the present invention, is to solve existing biological mark card developing technique, has and be easily destroyed biology
Mark card, determinand is size-constrained and equipment such as cannot carry at the problem.
For reaching above-mentioned purpose, the present invention provides a kind of sprayer unit for biological mark card development, makes a biology
Mark card is revealed and sees, includes: a container, and described container has an opening and with described opening even
Logical accommodation space；The mark card developing solution that one is placed in described accommodation space；And one be arranged at described
The atomizer of opening, described atomizer comprises a piezoelectricity concussion element contacting with described mark card developing solution,
Described piezoelectricity concussion element make described mark card developing solution form multiple liquid particulate via high-frequency vibration and
Discharge outside described container；Wherein, described mark card developing solution forms more described by described piezoelectricity concussion element
Liquid particulate is directly sprayed on described biological mark card by described opening, make described mark card developing solution directly with
Described biological mark card carries out redox reaction, and then manifests described biological mark card and see.
From the foregoing, the present invention compared to effect of prior art is:
1. by the mode sprayed, described mark card developing solution is applied to a determinand, therefore is not treated by described
Survey the restriction of thing size, also survivable described biological mark card.
2. described in, the sprayer unit volume for mark card development is light and handy, therefore is convenient for carrying and is beneficial to use.
3. can control the number of times spraying and coating weight, and can accurately coat described biological mark card, therefore solve
The problem that certainly described mark card developing solution is wasted.
4. liquid particulate described in can make described biological mark card more clearly visible be revealed out, improves described life
The resolution ratio of thing mark card identification.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as to the present invention's
Limit.
