Embodiment
The utility model is further described below in conjunction with the drawings and specific embodiments.
Embodiment 1:
See also Fig. 1-3, the pick-up unit of the utility model liquid sample comprises cup 1, bowl cover 12 and pedestal 2, the rim of a cup place of described cup 1 is movably installed with bowl cover 12, the bottom of described cup 1 is sealedly connected with pedestal 2, have slot 3 on the described pedestal 2, be inserted with the test card 13 of tape test bar 4 in this slot 3, described pedestal 2 is provided with the piston seat 5 that communicates with slot 3, vertically be provided with piston 6 in the described piston seat 5, this piston 6 is slipper seal with piston seat 5 and cooperates, one side of this piston 6 is provided with clamping platform 7, on described cup 1, be provided with the knob hole 8 of an end opening, this knob hole 8 is corresponding with clamping platform 7 positions, also include knob 9, this knob 9 passes described knob hole 8 and matches with clamping platform 7.
In this embodiment, the high 28mm of piston, two ends are the circle of diameter 14mm, are provided with O-ring seal apart from the about 3mm in two ends place.Be provided with a clamping platform 7 at the piston medium position for the knob clamping.The platform of clamping platform 7 for tilting, it is respectively 2mm and 3mm by two thickness plane with and the inclined-plane that is connected these two planes form, wherein on piston, over against the upper end position on 2mm and two planes of 3mm two baffle plates that are provided with vertically respectively that one is long and the other is short.
Knob 9 comprises clamping knob 10 and function knob 11, described clamping knob 10 has one and protrudes screens, this protrudes 7 one-tenth supporting forms of screens and clamping platform, promptly just in time be stuck between screens platform and two baffle plates, described clamping knob 10 passes knob hole 8 and matches with clamping platform 7, described function knob 11 1 ends are sheathed in the clamping knob 10, and the other end stretches out cup.Like this, handle rotary work button 11 moves piston 6 from top to bottom thereby play button 11 can drive clamping knob 10, liquid to be measured is transferred to quantitatively the socket portion of pedestal.
The cavity of cup can adopt any form, such as cylindrical, syringe-like shape, and chimney, perhaps other can be used for any form of storaging liquid.Rim of a cup place, cup 1 top is provided with external thread, and suitable with the internal thread of a bowl cover 12, and the sealing of bowl cover 12 is just finished by closely cooperating of internal and external threads.More preferably, be provided with O-ring seal in described tegmentum 12, like this, packoff prevents leakage effectively.The bowl cover outside is provided with anti-skidding striped, increases friction force and is convenient to open and tighten.
Be provided with interlayer between the bottom of described cup and the pedestal.Have one deck absorbent material in the described interlayer, be used to prevent to test leakage when carrying out and the pollution that causes.
Applying to test-strips of the present utility model can be usually said horizontal flow measurement test-strips, and the concrete structure of these test-strips and detection principle are persons skilled in the art technique known in the prior art.General commonly used test-strips is the nitrocellulose filter reagent strip, and promptly surveyed area comprises nitrocellulose filter, and fixedly specific binding molecules shows the result of detection on nitrocellulose filter, can also be cellulose acetate membrane or nylon membrane or the like.Test-strips can freely be carried out the test event combination, in this embodiment, 5 test-strips is arranged, and is respectively applied for to detect morphine, meth, head-shaking pill, ketamine, hemp.Test card is arranged with protective sleeve outward, its role is to protect test card and test paper (test-strips) located therein, and all or part of of it is transparent, so can not influence the change color of observation test bar.
When detecting, at first liquid sample is added in the cup main body by opening.Liquid sample after collecting and finishing is tightened bowl cover, exposes to cause the pollution of environment and sample in detection or transportation to avoid liquid sample.With the insert division in the insertion of the function knob in the packing clamping knob, before piston does not move, the piston slipper seal is arranged at piston seat, there is a segment distance (as shown in Figure 4) lower end of piston at the bottom of apart from piston seat, carries out detection reaction because the obstruct of piston makes liquid not flow to the test section position by piston; Function knob turns clockwise, and once revolve to the greatest extent, function knob drives the rotation of clamping knob, clamping knob driven plunger is moved from top to bottom, piston is displaced downwardly to piston seat bottom (as shown in Figure 5), the former like this liquid sample that is stored in the space, piston top and bottom moves down thereupon, because piston seat communicates with slot, after piston stops to move, the certain amount of fluid sample is transferred to the slot place of pedestal, the wetting test-strips that is installed in the slot of sample, test-strips is made according to competition inhibition method immunochromatography principle, and the paster at the watch window place that tears behind the certain hour reads the result.The liquid sample of cup can be delivered to the laboratory and further be detected by the professional, can not influence final testing result.
The sample of the utility model indication refers to that those can be used for detecting, chemically examining or diagnose the material that whether has analyte of interest matter.Sample can be blood, blood plasma, serum, urine, saliva and various juice, and the sample of collecting can be used for methods such as immune detection, chemical detection, enzyme detection and detect whether there is analyte.
Above-listed detailed description is at the specifying of the utility model possible embodiments, and this embodiment is not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
