Embodiment
Below in conjunction with one group of embodiment and accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model discloses a kind of from heating test card, this test comprises from top to bottom successively: top cover 1, comprise gland bonnet 2, main body 3 and elastic sealing gasket 4 fluid passage unit, from heating printed circuit board (PCB) 5, bottom 6.Main body 3 be included in top cover side formed have multiple reagent, at least one sample pool and waste liquid pool, and bottom side formed microfluidic channel.In this embodiment, test card has 4 reagent and a sample pool.The bottom of reagent and sample pool is provided with unpacking mouth.The import of flow microchannel is connected with each reagent by unpacking mouth, and its outlet is communicated with waste liquid pool.Gland bonnet 2 has the shape corresponding with sample pool to each reagent, for sealed reagent pond and sample pool.The sealing of microfluidic channel is compacted to main body 3 bottom surface by the elastic sealing gasket 4 between main body and printed-wiring board (PWB) 5 and realizes.The waste liquid pool top top cover 1 being provided with supersonic welding wiring seals.Elastic sealing gasket 4 is attached to and is integrated with on the printed circuit board (PCB) 5 of magneto-dependent sensor, the bottom 6 being provided with supersonic welding wiring is fastened on printed circuit board (PCB) 5 bottom, engaged by ultra-sonic welded with main body 3, and elastic sealing gasket is compacted to the bottom microfluidic channel sealing that main body 3 makes main body 3.Also other positions of test card can be arranged on as required from heating printed circuit board (PCB).
As shown in Figures 2 and 3, the utility model shows printed circuit board (PCB) heating wire heating unit wiring diagram and the distribution schematic diagram for certainly heating test card.Heating unit can be the single electric heating unit of overall routing, also can be the multiple electric heating units being connected in series after the diverse location of printed circuit board (PCB) connects up respectively or being connected in parallel.The plain conductor that heating unit selects the metal coating on printed circuit board (PCB) 5 to be formed, as the main body of heating wire, connects up in S shape mode and increases plain conductor length of arrangement wire.The plain conductor of heating unit can be formed on the same side of printed circuit board sensors circuit, also can be formed on the opposite side of printed-wiring board (PWB) sensor circuit.Preferably, plain conductor wire location can arrange the position of reagent and the heating of sample needs as required.By the thickness that controls metal coating and the live width of plain conductor formed, the resistance value of heating wire can be controlled, such as, at 8 ~ 10 Ω.During application, the program control adjustable electric depressor of the independence as power supply, by the heater strip terminals access voltage of metal probe to test card, forms loop, generation current.By controlling alive size of executing, making controllable current flow through heating wire, is the heat energy of heating wire by electric energy conversion, realizes the object heated as liquid reagent and sample the reagent on test card and test card.
Due to the existence of magnetic effect of electric current, the heater strip of energising will produce magnetic field.The existence of this additional field produces extra response signal by making sensor or its signal exported, and introduces noise in the output signal, affects measuring accuracy and accuracy.Fig. 4 illustrates the S shape wire laying mode from heating test card internal printed circuit board heating wire of the present utility model and current trend schematic diagram.Use S shape wire laying mode in the present embodiment, preferably, adopt single line S shape and comprise the wire laying mode partly that extends parallel to each other, ensure that in adjacent rows wire, direction of current is contrary.Heating instantaneous moment arbitrarily, the magnetic field that adjacent rows electric current produces is equal, but direction is contrary, offsets completely mutually.On whole printed circuit board (PCB), the shape according to circuit board is arranged successively within the scope of heater strip wiring, the additional field caused when can heater strip be avoided completely to be energized.
In sum, technical scheme described in the utility model forms heating wire in test card internal printed circuit board, saves independent heating sheet, without the need to considering the attaching process of heating plate and test card again, can save physical space, reducing cost of products.Heater strip is in the printed circuit boards integrated, do not have to fit in external heating plate and printed circuit board (PCB) bonding structure the impact of temperature conductivity, test card shell temperature conductivity factor, can the efficiency of heating surface be improved, reduce heating power, promote the object that heat energy service efficiency reaches environmental protection more.After integrated heating silk, the batch of printed circuit board (PCB) is shaping compare laminating heating plate after the shaping repeatability of batch of test card higher, therefore from heating test card performance reproducibility far away higher than the heating means of external heating plate, add the dependable with function of product.
Can be understood as, the utility model is described by some embodiments, and those skilled in the art, when not departing from spirit and scope of the present utility model, can carry out various change or equivalence replacement to these characteristic sum embodiments.In addition, under instruction of the present utility model, can modify to adapt to concrete situation and material to these characteristic sum embodiments and spirit and scope of the present utility model can not be departed from.Therefore, the utility model is not by the restriction of specific embodiment disclosed herein, and the embodiment in the right of all the application of falling into all belongs to protection domain of the present utility model.
