Description
Technical field
The utility model relates to a kind of grass-roots method medicinal detection device, and specifically under a kind of mirror, human body comes offCell extraction device.
Background technology
One of main contents that current domestic grass-roots method medical professionals does are any may being stained with in extraction sceneSuspect's object, comprising: instrument, clothing, gloves, contactant, and bloodstain, salivary stain,Seminal stains etc., these unifications are referred to as material evidence, have been summed up four for the processing method of these material evidencesKind, both vacuum suctions, adhesive tape adheres to, cotton swab wiping, original clip. For different body surfacesCharacteristic, adopts above diverse ways can more effectively shift human body cast-off cells, but also allThere is different problems. On the whole, these four kinds of methods are all to process microcosmic thing by macroscopical methodMatter, has certain blindness. First, the frequency of utilization of vacuum suction is not high, does not possess in basic unitThe unit of experimental facilities, can not make to carry out in this way just to extract superior censorship again, problem substantiallyBe, one, this method is harsher to operating environment, wants to accomplish not pollute sample, necessaryKeep extracting the environment facies that shift sample when clean, but this point does and has many difficulties, itsTwo, laboratory DNA sample to be processed every day is tens examples up to a hundred nearly, and the method for complex operation is more aobviousApplicability deficiency, with regard to current DNA effect case, is scarcely that sufficient manpower, thing can be providedThe major and serious criminal case part of power and fund, but every day is all in case usually such as the theft, the robbery etc. that occur, replyQuantity huge, it is more crucial that efficiency seems on the contrary; Secondly, adhesive tape adhesion, cotton swab wiping, the originalThese three kinds of methods of clip will be in two kinds of situation, if while adhering to obvious human body component on sample,Such as bloodstain and salivary stain, this three kinds of methods are fairly simple effectively, on the contrary, if instrument, clothesAbove significantly do not extract target, these methods are comparatively followed blindly so, and need employing repeatedly to extractMethod makes up omission, so just causes poor in timeliness, the situation of waste money. In real workReflect, the DNA recall rate wretched insufficiency of case, can not well serve cracking of cases usually, changesIndividual saying also can say that the method cost performance of these examination of material evidences is very low.
