Technical Field

The utility model relates to a device is got in gluing of trace material of examining such as biological desquamation cell, especially a device is got in gluing of examining material.

Background

The DNA inspection of the exfoliated cells is closely related to the extraction and storage of the inspection materials in the crime scene, the condition that the exfoliated cells are fully transferred from the scene carrier to the laboratory carrier in the crime scene is the premise of successful DNA inspection, and the guarantee of full transfer of the exfoliated cells is provided by a correct extraction method, a proper transfer medium and an effective extraction device.

The detection material is the fallen object left by the criminal suspect in the crime scene, such as saliva, scurf, hair and the like, and the effective extraction of the contact type biological material evidence in the current case scene is the key point for detecting the case. Because the quantity of the biological material evidence is very small and the biological material evidence belongs to trace biological detection materials, the improvement of the extraction efficiency of the field material evidence is particularly important. The existing main extraction method for the on-site biological evidence is through a cotton swab, and the usage rate of the cotton swab accounts for 80% of the contact cases.

In the existing on-site investigation, too much uncertainty exists, part of criminal suspects carry out careful cleaning on the criminal site, so that fewer fallen objects are available, which is difficult for criminal investigation officers, and every criminal suspects can check tools or places where the criminal suspects may use or rest to find the fallen objects of the criminal suspects; sometimes, a crime suspect casting tool needs to be observed through a microscope, the casting tool searches for the casting through the microscope, after the casting is observed through the microscope, a single casting with a small volume is not easy to extract through a conventional cotton swab extracting mode, and a single cell is easy to fall off through the cotton swab extracting mode, so that the loss or cross contamination of the casting substances which can be found is caused, the trend of a case is uncertain, the difficulty of case solving is increased, and the social loss caused by the fact that the case cannot be timely detected cannot be measured.

As the utility model discloses an optimal scheme, the round bar with through-hole clearance fit makes things convenient for the round bar to make a round trip to move about in the through-hole of body.

As the utility model discloses a preferred scheme, the body is kept away from extraction portion one end is provided with the convex part, when the round bar carries out the dismantlement of extraction portion, and when the round bar was held to the hand, place the hand and borrow the power on the convex part, improved the dismantlement efficiency of extraction portion.

As the utility model discloses an optimal scheme, the portion of drawing is kept away from adhesive film one end is the boss, the boss is big end down setting, the through-hole with the portion of drawing is connected one end and is set up to the opening of "eight" font, the boss conveniently with the through-hole cooperation of body, improve the installation effectiveness of the portion of drawing.

As a preferable embodiment of the present invention, the adhesive film is an elastomer type pressure sensitive adhesive or a resin type pressure sensitive adhesive.

As the preferred scheme of the utility model, the diameter of gluing the section is 0.1mm ~ 1 mm.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. structural viscous film that has set up in the big-end-up of portion of drawing, observe the junk under the microscope after, through handheld body to junk department, the viscous film glues and gets the junk for the junk can not drop, makes can guarantee to draw the junk in as early as possible time, improves the extraction efficiency to the junk.
