Abstract
A kind of material evidence acquisition rod; including hollow barred body 1; pure water 3 is stored in the cavity of barred body 1; it is wrapped in the flocking swab 2 of the one end of barred body 1; barred body 1 is provided with least two aperture 4 at the position of parcel flocking swab 2; the pure water being easy in rod spreads rapidly, uniformly to flocking swab 2, and the pure water of the storage in barred body 1 easily volatilizees, so setting oil sealing protection at the end opening of flocking swab 2 of barred body 1.
Description
Technical field
The utility model is related to a kind of acquisition rod, more particularly to it is a kind of be used for that public security to be criminal and other kinds site inspection in
Material evidence gathers the material evidence acquisition rod with extracting.
Background technology
At present applied to public security is criminal and other kinds site inspection in material evidence collection be generally cotton swab, this kind of cotton swab makes
Used time, it is necessary to first soak the pure water in viscous water bottle, the collection and extraction of material evidence are then carried out again.Such cotton swab has the disadvantage that：1.
Cotton swab and pure water are separately carried, it has not been convenient to carried；2nd, the separation of cotton swab and pure water can cause artificially-contaminated possibility increase；3、
During the viscous pure water of cotton swab leaching, the amount of absorption pure water is difficult to control, adsorbed pure water amount is easily caused very little or too many and then influence
DNA recall rate.The purpose of this utility model is to provide a kind of low simple in construction, cost, convenient use, can improve recall rate
Gravity flow material evidence acquisition rod easy to break.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of material evidence acquisition rod, and its is more convenient to use, be easy to
The possibility of pollution is carried, reduced, DNA recall rate is improved.Therefore, the utility model uses following technical scheme：Including rod
Body and flocking swab, the barred body are tubulose and hollow, and the flocking swab is wrapped in barred body one end, and the barred body other end is used
Direct heat seal closing, the tubulose barred body doubles as container, and the flocking swab is gathered for material evidence.
The flocking swab is wrapped in barred body one end, offers aperture, oil sealing protection is set at opening, be easy to pure in barred body
Water is rapid, uniformly soak flocking swab.
The barred body other end is provided with frangible lines close at blind end.
The barred body is provided with cavity, and cavity is mainly used in storing pure water.
Due to using the technical solution of the utility model, the utility model discrete is few, exchanges replacing product conveniently, tie
Structure is simple, cost is low, easy to use, recall rate is high, is difficult pollution, can and other all kinds of site inspection thing criminal as public security
Card collection and the necessity extracted.
Brief description of the drawings
Accompanying drawing 1 is the utility model structural representation
1. barred body in figure, 2. flocking swabs, 3. cavitys, 4. apertures, 5. sealings, 6. broken lines,
Embodiment
As shown in figure 1, the utility model is included in hollow barred body 1, barred body 1 provided with cavity 3 for storing pure water, it is wrapped in
The flocking swab 2 of the one end of barred body 1, barred body 1 is provided with least two aperture 4 at the position of parcel flocking swab 2, is easy to pure in rod
Water is rapid, uniformly spread to flocking swab 2, and the pure water of the storage in barred body 1 is volatile, so at the end of flocking swab 2 of barred body 1
Oil sealing protection is set at opening.The other end of barred body 1 can be closed with direct heat seal, and barred body 1 is close at blind end, provided with easy to break
Broken string 6.In the utility model, the amount of pure water is added in barred body cavity to be controlled, and be preferably controlled in frangible lines 6 and barred body 1
Between the perforate 4 of end.The materials'use polypropylene plastics of barred body is made, it is necessary to keep certain mechanical strength.Use this reality
When using new, fracture barred body at frangible lines by the flocking swab of barred body downwards, and the pure water of barred body is due to the effect general of gravity
Rapidly, it is uniformly spread in flocking swab, material evidence acquisition rod is that can be used.
