Summary of the invention
The purpose of this invention is to provide a kind of pick-up unit that can detect drugs and alcohol simultaneously.
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 the application of sample 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 the housing, and a water absorptivity drainage part part is placed in the application of sample mouth of housing, another part be connected with the 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 application of sample mouth of housing and are not connected.So design, after the detection sample was added in the application of sample mouth, water absorptivity drainage part was transferred to sample respectively the 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 the bed hedgehopping structure, and this bed hedgehopping support structure crossing current detecting element and alcohol detection pad make its position be higher than the bottom of housing application of sample mouth.Housing has a projection, and this projection is pressed into the part of water absorptivity drainage part in the application of sample mouth of housing, thereby under capillary force sample is transferred to crossing current detecting element and alcohol detection pad by the application of sample 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 crossing current sample application zone of detecting element and alcohol detection pad, reduce the sample that joins alcohol pads be subjected to the flowing over influence 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 effectively and be subjected to the influence 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 ", the base portion of its broad extends in the application of sample mouth of housing, three narrower branches separated by breach and extend the application of sample mouth of housing after be connected with the 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 to take 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 application of sample mouth place, have a plate washer that is used to stop sampling head to enter the application of sample mouth to allow sample to enter the hole of application of sample mouth with at least one between this passage and the application of sample 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 the application of sample mouth, thereby sampling head can be remained in the 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 combines 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 the absorber element that is used to absorb unnecessary sample in the housing, this absorber element is a 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 the drugs that whether include drugs or its metabolin in the chromatography detection sample to detect test paper, and the alcohol detection pad includes the composition that is used to detect alcohol or its metabolin.
The invention has the beneficial effects as follows: owing to drugs are detected and alcohol detection focuses on the device, thereby this pick-up unit can once carry out the detection of drugs and alcohol simultaneously, have simple to operate, quick, operating efficiency height, the advantage that cost is low.Simultaneously, owing to adopt water absorptivity drainage part to utilize siphon principle the sample sample to be incorporated into the sample application zone and the alcohol detection pad of crossing current detecting element respectively from the application of sample mouth after the shunting of water absorptivity drainage part, reduce sample be subjected to the flowing over pollution and the interference of composition in detecting element and the alcohol detection pad effectively, helped improving the accuracy of detection.In addition, owing between passage and application of sample mouth, be provided with plate washer, the sampling head of sampling instrument can not be run into 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 take place after inserting passage.
