Technical field
The present invention relates to a kind of pick-up unit, relate in particular to and a kind ofly can carry out simultaneously the pick-up unit of illicit drugs inspection and alcohol detection.
Background technology
Drug abuse and drive when intoxicated and brought very large harm to society.Multinational statutory regulation need to carry out drug abuse and the inspection of driving when intoxicated in some occasion.Correspondingly, some disposable small and exquisite drug abuse pick-up unit and alcohol detecting device have appearred on market, but these devices or can only carry out drug abuse and detect, can only carry out alcohol detection, also do not occur on market carrying out simultaneously the device of drug abuse detection and alcohol detection, do not occur such open source information yet.Yet many times drug abuse and excessive drinking are simultaneous, thereby necessary developing a kind ofly can be carried out the device of drug abuse detection and alcohol detection simultaneously.So, the testing staff only needs to take sample one time to those who are investigated, and carry out one-time detection and can obtain two kinds of even multiple check results, thereby special convenient, and testing cost significantly reduces, and the rubbish that produces when being abandoned after pick-up unit uses has also correspondingly reduced.
Summary of the invention
The purpose of this invention is to provide a kind of pick-up unit that can detect simultaneously drugs and alcohol.
Technical scheme of the present invention is: pick-up unit comprises housing and is housed in housing interior crossing current detecting element and alcohol detection pad.The crossing current detecting element comprises sample application zone, mark zone and testing result viewing area.Housing is provided with adding mouth and corresponds respectively to the testing result viewing area of crossing current detecting element and the testing result display window of alcohol detection pad.Pick-up unit also comprises the water absorptivity drainage part that is housed in housing, and a water absorptivity drainage part part is placed in the adding mouth of housing, another part be connected with sample application zone and the alcohol detection pad of crossing current detecting element respectively (for example overlap joint) mutually.Alcohol detection pad and crossing current detecting element are positioned in outside the adding mouth of housing and are not connected.So design, after the detection sample was added in adding mouth, water absorptivity drainage part was transferred to sample respectively sample application zone and the alcohol detection pad of crossing current detecting element according to siphon principle under capillary force, detect.
As a further improvement on the present invention, the enclosure interior of pick-up unit is provided with padded structure, and this padded support structure crossing current detecting element and alcohol detection pad make its position higher than the bottom of housing adding mouth.Housing has a projection, and this projection is pressed into the part of water absorptivity drainage part in the adding mouth of housing, thereby under capillary force, sample is transferred to crossing current detecting element and alcohol detection pad by adding mouth.
As a further improvement on the present invention, the water absorptivity drainage part of pick-up unit has at least two branches that separated by breach, these at least two branches are connected with the alcohol detection pad with the sample application zone of crossing current detecting element respectively, so can make sample just shunting before entering into the crossing current sample application zone of detecting element and alcohol detection pad, effectively reduce the sample that joins alcohol pads be subject to the flowing over impact of reagent composition in the sample application zone of detecting element and the sample that joins the sample application zone of crossing current detecting element and be subject to the impact of reagent composition in the alcohol detection pad.
As a further improvement on the present invention, the water absorptivity drainage part of pick-up unit has the structure of capitalization English letter " E ", its wider base portion extends in the adding mouth of housing, three narrower branches separated by breach and extend the adding mouth of housing after be connected with sample application zone and the alcohol detection pad of crossing current detecting element respectively.
As a further improvement on the present invention, pick-up unit also comprises a sampling instrument that is used for taking sample, this sample man has a sampling head, the housing of pick-up unit is provided with a passage that allows sampling head to pass through at the adding mouth place, have a plate washer that is used for stoping sampling head to enter adding mouth and at least one to allow sample to enter the hole of adding mouth between this passage and adding mouth.
As a further improvement on the present invention, the housing of pick-up unit has designed at least one wedge-shaped projection on the inwall of passage, one end of this at least one wedge-shaped projection point is towards the outlet of passage, and a blunt end is towards adding mouth, thereby sampling head can be remained in passage.
As a further improvement on the present invention, the sampling instrument inserts the passage of housing of pick-up unit at sampling head after, the sampling instrument is combined with this vias inner walls hermetic seal, thus can prevent sample from passage to the housing external leakage.
As a further improvement on the present invention, also comprise in housing be used to the absorber element that absorbs unnecessary sample, this absorber element is water-absorbing material, thereby can prevent further that sample is to the housing external leakage.
As a further improvement on the present invention, the crossing current detecting element is to adopt chromatography to detect the illicit drugs inspection test paper that whether includes drugs or its metabolin in sample, and the alcohol detection pad includes the composition for detection of alcohol or its metabolin.
The invention has the beneficial effects as follows: due to illicit drugs inspection and alcohol detection are focused on a device, thereby this pick-up unit can once carry out the detection of drugs and alcohol simultaneously, has simple to operately, quick, and operating efficiency is high, the advantage that cost is low.Simultaneously, owing to adopting water absorptivity drainage part to utilize siphon principle the sample sample to be incorporated into respectively sample application zone and the alcohol detection pad of crossing current detecting element from adding mouth after the shunting of water absorptivity drainage part, effectively reduce sample be subject to flowing over pollution and the interference of composition in detecting element and alcohol detection pad, be conducive to improve the accuracy of detection.In addition, owing to being provided with plate washer between passage and adding mouth, the sampling head of sampling instrument can not be encountered crossing current detecting element, alcohol detection pad and water absorptivity drainage part, thereby has avoided sampling head to cause the phenomenon of crossing current detecting element, alcohol detection pad and the displacement of water absorptivity drainage part to occur after inserting passage.
Moreover, because the sampling instrument coordinates with the channel seal of housing, and be provided with the absorber element of being made by water-absorbing material in housing, even when adding excessive sample, sample can not leak into beyond housing yet, has advantages of clean hygiene.
