Description

A kind of novel micro material evidence Adhesive-fetch device

Technical field

The utility model relates to a kind of novel micro material evidence Adhesive-fetch devices.

Background technique

Micro biological material is acquired at the scene, then collected micro biological material is sent to laboratory and carries out method Medical verification can effectively improve criminal case according to Forensic Identification result and crack efficiency.Micro life is acquired at narrow gap Quality testing material is always a great problem of micro biological material acquisition, while after collecting micro biological material, transporting to its inspection In the process, the trace material evidence being attached on swab is easy to fall off because of vibration, increases difficulty to Forensic Identification, also reduces method The accuracy of medical verification.

Utility model content

Technical problem to be solved by the utility model is: providing a kind of novel micro material evidence Adhesive-fetch device, the prior art is solved Trace material evidence is easy to fall off during acquiring difficult micro biological material and inspection at narrow gap, to increase medical jurisprudence The problem of identifying difficulty and reducing Forensic Identification accuracy.

To achieve the above object, the technical solution adopted in the utility model is as follows:

A kind of novel micro material evidence Adhesive-fetch device is connected to the bottom surface center of the handle including cylindrical handle vertically And connecting rod cylindrical, it is fixed on the swab of the connecting rod free end, and be socketed on the bottom end of the handle and be used for Cover the outer cover of the connecting rod and the swab；The outer surface of the swab be fixed with one layer it is viscous take layer, the outer cover is in column Shape, and its at least one side is plane, and the handle also is provided with handle plane in side corresponding with the plane, The plane is equipped with fixed mechanism, and outer cover is pasted equipped with label, and label patch and the plane face.

Further, the connecting rod is equipped with easy breakpoint, and the easy breakpoint is close to the swab.

Further, the bottom end of the outer cover and the handle is tight fit.

Further, the outer cover is made of transparent material.

Further, the label reclines the open end of the nearly outer cover.

Further, the swab is in sharp cone distal.

Further, the fixed mechanism is PE foam double-faced adhesive, and the inner layer of the double-sided adhesive is pasted onto the plane On, outer layer is pasted with one layer of release paper.

Compared with prior art, the utility model has the following beneficial effects:

The utility model structure is simple, design is scientific and reasonable, easy to use, and criminal investigation personnel can be facilitated in narrow gap Middle acquisition trace material evidence, while the phenomenon that micro biological material falls off in transport and delivery process is avoided, so that subsequent experimental Room tests and analyzes more convenient and accurate.

The utility model aims at the scene of a crime acquisition micro sample of DNA and designs, and especially designs in the swab of sharp cone distal, side Just it reaches and extracts blood cake in narrow gap, seminal stain, the biological materials such as cast-off cells.The utility model does not need to dip in water wiping, directly It connects to glue and takes micro biological material, criminal investigation personnel is facilitated to acquire trace material evidence.The utility model outer cover is transparent, acquires micro Material evidence situation is intuitively visible；Exclusive outer cover design, avoids impurity in outside air from polluting biological material；It is easily broken in connecting rod The broken design of point is avoided and is contaminated using the shearing such as scissors swab bring Qian sewage, is conducive to subsequent DNA purification process.Outside The planar design of lid can prevent generation rolling during inspection from falling damage, and PE foam double-faced adhesive can make the utility model firm In containing box, micro biological material can be effectively prevent to cause Forensic Identification difficulty to increase because vibration falls off during inspection Accuracy with Forensic Identification is reduced, can also prevent micro biological material during inspection because high vibration leads to micro life The damage of quality testing material.

Wherein, the corresponding title of appended drawing reference are as follows:

1- handle, 2- connecting rod, 3- swab, 4- outer cover, 5- are viscous to take layer, 6- plane, 7- handle plane, the easy breakpoint of 8-, 9- Label patch, 10- fixed mechanism, 11-PE foam double-faced adhesive, 12- release paper.

Specific embodiment

The utility model is described in further detail with embodiment for explanation with reference to the accompanying drawing, and the mode of the utility model includes But it is not limited only to following embodiment.

As shown in Figure 1-3, a kind of novel micro material evidence Adhesive-fetch device provided by the utility model, structure is simple, design science Rationally, easy to use, criminal investigation personnel can be facilitated to acquire trace material evidence in narrow gap, while avoiding transport and delivering The phenomenon that micro biological material falls off in the process, so that the detection and analysis of subsequent experimental room are more convenient and accurate.The utility model Including cylindrical handle 1, it is connected to the bottom surface center of the handle 1 and connecting rod 2 cylindrical vertically, is fixed on described The swab 3 of 2 free end of connecting rod, and the bottom end of the handle 1 is socketed on for covering the connecting rod 2 and the swab 3 Outer cover 4, the bottom end of the outer cover 4 and the handle 1 is tight fit, and the outer cover 4 is made of transparent material, the swab 3 be in sharp cone distal, and the connecting rod 2 is equipped with easy breakpoint 8, and the easy breakpoint 8 is close to the swab 3.

The outer surface of swab 3 described in the utility model be fixed with one layer it is viscous take layer 5, the outer cover 4 is cylindrical, and it is extremely A rare side is plane 6, and the handle 1 also is provided with handle plane 7 in side corresponding with the plane 6, described flat Face 6 is equipped with fixed mechanism 10, and the fixed mechanism 10 is PE foam double-faced adhesive 11, and the inner layer of the double-sided adhesive is pasted onto institute It states in plane 6, outer layer is pasted with one layer of release paper 12, and the outer cover 4 is equipped with label patch 9, and label patch 9 and institute 6 face of plane is stated, the label patch 9 is close to the open end of the outer cover 4.

When the utility model is used, first removing outer cover from handle, holds handle and swab is aligned in narrow gap Trace material evidence acquisition zone to be collected takes layer is viscous to take trace material evidence by viscous, again connects outer cover lid in handle after trace material evidence acquisition On, label patch can mark acquisition time and specific acquisition position；In inspection, the release paper in PE foam double-faced adhesive is torn Falling, this Adhesive-fetch device is lain in and is collected in case, this Adhesive-fetch device can be firmly pasted by PE foam double-faced adhesive to be collected in case, even if Generating big vibration will not cause this Adhesive-fetch device to damage, and can effectively ensure that the safe inspection of micro biological material.When inspection finishes It when being detected, can be fractureed easily by easy breakpoint, can effectively avoid and dived using the shearing such as scissors swab bring in sewage Dye.
