Abstract
The utility model discloses a laminar flow cover of a liquid treatment platform for a forensic medical STR (suspend to ram) database work station, which comprises a cover body and an air blast mechanism arranged at the top end of the cover body. The air blast mechanism comprises an air blast chamber, a pre-filtering layer, a fan seat and a fan, a ventilating opening is arranged at the top end of the air blast chamber, the pre-filtering layer is disposed below the ventilating opening, the fan seat is fixedly arranged at the lower end of the air blast chamber, the fan is disposed in the fan seat, and a filter layer and a damping layer are successively disposed in the cover body below the air blast mechanism from top to bottom. The laminar flow cover can provide a clean work environment for a previous PCR (polymerase chain reaction) stage, can effectively reduce DNA (deoxyribonucleic acid) cross contamination at the previous PCR treatment stage.
Description
Technical field
The utility model relates to a kind of laminar flow hood, is specifically related to a kind of laminar flow hood that purifies legal medical expert STR database work station liquid handling platform internal environment that is specifically designed to.
Background technology
DNA pollutes (DNA contamination) and is meant that biological material evidence sample is mixed with the external source biological substance that contains DNA in extraction or checkout procedure, causes the result of DNA check to change.
Before PCR the processing stage DNA cross pollution of (specimen dna extracts the stage) be one of major reason of PCR experimental pollution, can form aerosol or spread and a major reason that causes the DNA cross pollution is exactly some sample with aerosol, especially the easier formation aerosol of virus or spread with aerosol, all be under an environmental condition of having been polluted, to finish usually PCR the processing stage before this causes by aerosol, thereby make between sample and sample, a large amount of cross pollutions take place between sample and virus, influenced final PCR experimental result.In addition; when extracting specimen dna; DNA is retained in the platform on the table top and module through reasons such as regular meeting's splashing when uncapping, and this also is a major reason of DNA cross pollution, and can quick and conveniently eliminate these residual DNAs efficiently also be the key that reduces the PCR experimental pollution.
The liquid handling platform at work on hand station does not all have laminar flow hood, can not guarantee the cleaning of the local environment in the liquid handling platform, is difficult to assurance like this and effectively controls environment to the pollution of sample.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, the laminar flow hood of a kind of legal medical expert STR database work station liquid handling platform is provided, the utility model can provide the working environment of a cleaning for the preceding PCR stage, can effectively reduce the DNA cross pollution that takes place the processing stage of preceding PCR.
The purpose of this utility model realizes by following scheme: the laminar flow hood of a kind of legal medical expert STR database work station liquid handling platform, it is characterized in that: the laminar flow hood of described legal medical expert STR database work station liquid handling platform comprises cover body and is arranged on the Blast mechanism on this cover body top, described Blast mechanism comprises blast chamber, pre-filtering layer, blower fan seat and blower fan, the top of described blast chamber is provided with ventilating opening, described pre-filtering layer is arranged on the below of described ventilating opening, described blower fan seat is fixedly installed on the lower end of described blast chamber, described blower fan is arranged in the described blower fan seat, in described cover body, be positioned at described Blast mechanism below be disposed with filter course and damping layer from top to bottom.
Also be provided with uviol lamp in the described cover body, this uviol lamp is positioned at the below of described damping layer.
Also be provided with fluorescent lamp in the described cover body, this fluorescent lamp is positioned at the below of described damping layer.
The top of described cover body is provided with at least two described Blast mechanisms.
Advantage of the present utility model is: the utility model can provide the working environment of a cleaning for the preceding PCR stage, can effectively reduce the DNA cross pollution that takes place the processing stage of preceding PCR.
Description of drawings
Fig. 1 is the structural representation of the laminar flow hood of legal medical expert STR database work of the present utility model station liquid handling platform.
Description of reference numerals: cover body 1; Blower fan 2; Ventilating opening 3; Filter course 4; Pre-filtering layer 5; Control panel 6; Damping layer 7; Fluorescent lamp 8; Uviol lamp 9; LCD 10; Function key 11; Blower fan seat 12; Blast chamber 13.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the laminar flow hood of a kind of legal medical expert STR database work station liquid handling platform, comprise cover body 1 and the Blast mechanism that is arranged on this cover body 1 top, Blast mechanism comprises blast chamber 13, pre-filtering layer 5, blower fan seat 12 and blower fan 2, the top of blast chamber 13 is provided with ventilating opening 3, pre-filtering layer 5 is arranged on the below of ventilating opening 3, blower fan seat 12 is fixedly installed on the lower end of blast chamber 13, blower fan 2 is arranged in the blower fan seat 12, in cover body 1, be positioned at Blast mechanism below be disposed with filter course 4 and damping layer 7 from top to bottom.
When work, blower fan 2 starts, blower fan 2 makes air enter in the blast chamber 13 by pre-filtering layer 5 from the ventilating opening 3 on laminar flow hood top, again with after speed is passed through filter course 4 and damping layer 7 definitely, clean air is perpendicular layers flow pattern air-flow and sends into the workspace, thereby has guaranteed the cleanliness factor that experimental situation requires in the workspace.
In the utility model, also be provided with uviol lamp 9 in the cover body 1, this uviol lamp 9 is positioned at the below of damping layer 7, because uviol lamp 9 has the effect of sterilization, it can eliminate residual sample of nucleic acid influenced the preceding PCR stage.Also be provided with fluorescent lamp 8 in the cover body 1, this fluorescent lamp 8 is positioned at the below of damping layer 7, and fluorescent lamp 8 is used for the illumination of operating environment.In the utility model, the needs according to the PCR experiment can be provided with at least two Blast mechanisms on the top of cover body 1.
In addition, at the outer surface of cover body 1 control panel 6 can be set, control panel 6 is provided with LCD 10 and is respectively applied for the function key 11 of control blower fan 2, uviol lamp 9, fluorescent lamp 8 work.The utility model can also increase remote control control function, by the work of this function control layer stream cover, can avoid ultraviolet ray and because of the actual bodily harm to operating personnel of ozone that ultraviolet oxidation air produced.
