Description

Material evidence cotton swab protective case

Technical field

The utility model relates to the extraction Techniques of preserving fields of biological material, and in particular to a kind of material evidence cotton swab protective case.

Background technique

The biological materials such as blood, saliva, cast-off cells are frequently involved in forensic science, health care and field of biotechnology Acquisition, packaging and save problem.Especially in forensic science field, the complicated multiplicity of the biological material of test sensitivity is needed, and And frequently encounter micro cast-off cells sample.The store method of sample is improper, and be easy to causeing sample to be lost or pollute causes to examine Failure is tested, therefore sample loses evidence value.

Currently, biological material acquisition and store method are usually directly to acquire the biological materials such as blood, cast-off cells in cotton Sign, after dried in shady place；Or the mottlings such as bloodstain, salivary stain or exposing cell are speckled with the cotton swab of the wettings such as distilled water Position, cleaning piece dries in shady place, is placed in ventilative Material evidence bag and saves.When drying cotton swab, cotton swab is not easy to place, wipes The cotton swab head for wiping sample, which becomes easily infected by other places, causes sample to pollute, and the cotton swab after drying is placed in ventilative Material evidence bag It saves and is also easy the contact because of cotton swab head with packaging material so that the sample size reduction being infected on cotton swab, is unfavorable for subsequent identification Work.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of structure simple, at low cost, easy to use material evidence cotton Sign protective case.

The technical solution of the utility model is as follows:

A kind of material evidence cotton swab protective case, the lid including cylindrical cotton swab socket and long tubular, the cotton swab socket it is upper Portion is hollow cotton swab insertion cylinder, lower part is pedestal, and the cross-sectional area of the cotton swab insertion cylinder is less than the cross section of the pedestal Product, cotton swab are inserted into cylinder and are inserted into for cotton swab, and pedestal is provided with desiccant, venthole, the lid are provided on the top surface of pedestal It is matched with outside pedestal with pedestal.

Preferably, it is provided with adhesive-layer on the inner surface of the sealing plate of the closed end of the lid, is wiping certain bands After broken small block-like material evidence, the material evidences such as cell are attached in swab stick, but some broken small impurity may fall off, and close the lid Afterwards, the impurity to fall off adhesive can be clung, and after entering laboratory, viscose glue enters laboratory vector in company with cotton swab head together, Adherency cast-off cells DNA thereon is carried out to examine.Preferably, the pedestal is cylinder, is provided in the middle and upper part of pedestal Around the boss of pedestal, the cross section of the boss is rectangle.On the one hand the setting of boss makes cotton swab socket be placed on ground sidewards It will not arbitrarily be rolled when face, on the other hand in wiping extraction process, operator is held on rear side of baffle and not will cause in casing Pollution.

Preferably, the cotton swab insertion cylinder is cylinder, is easily worked manufacture, matches with swab stick shape.

Preferably, the case where material of the lid is transparent material, facilitates cotton swab in observation lid.

The beneficial effects of the utility model are: structure novel is simple, making material source is wide, is easy production, is at low cost, making With conveniently.Using the utility model, the cotton swab that wiping has sample can be saved well, prevented sample contaminated, adopted sample i.e. It can be placed in immediately in the protective case and be saved, it is very convenient.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples:

Embodiment 1

A kind of material evidence cotton swab protective case as shown in Figure 1, is made of the lid 2 of cylindrical cotton swab socket 1 and long tubular.Cotton The top of label socket 1 is hollow cotton swab insertion cylinder 3, lower part is pedestal 4, and the cross-sectional area that cotton swab is inserted into cylinder 3 is less than pedestal 4 Cross-sectional area, cotton swab are inserted into cylinder 3 and are inserted into for cotton swab.It is cylinder that cotton swab, which is inserted into cylinder 3 and pedestal 4, is set in the middle and upper part of pedestal 4 It is equipped with the boss 4b around pedestal 4, the cross section of boss 4b is rectangle, so that cotton swab socket 1 will not when being placed on ground sidewards It rolls.Pedestal 4 is provided with desiccant, and venthole 4a is provided on the top surface of pedestal 4, and lid 2 is matched with bottom with pedestal 4 Outside seat 4.Adhesive-layer 2b is provided on the inner surface of the sealing plate 2a of the closed end of lid 2.The material of lid 2 is transparent material, side Just the case where observing swab stick.

Cotton swab is inserted into cylinder 3 and pedestal 4 or square column, when cotton swab insertion cylinder 3 is rectangular, does not need in pedestal 4 Upper setting boss 4b can avoid the protective case and place sidewards to roll on the table.

The cotton swab for having wiped material evidence, closes the lid 2, and the cell adhered in swab stick is fallen to be clung by the adhesive-layer 2b of lid 2 To which the trace material evidence adhered in swab stick will not be influenced again.Desiccant in pedestal 4 passes through venthole 4a for the aqueous vapor in lid 2 It siphons away, keeps the influence in lid 2 in dry condition, reduction high humility to material evidence in swab stick.
