Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the diagnostic device 100 of first embodiment of the invention comprises a test paper disk 50 and a test paper disk reader 60.
This test paper disk 50 is for the variation at urine and/or blood test biological respinse.In the present embodiment, this test paper disk 50 comprises a test paper 51 and checks lines 53 to show assay by producing a control line 52 and two on the particular location at this test paper 51.Concrete, this test paper 51 has unified background colour before use, for example white, and after use, and this test paper 51 may pulverize redness (occurring this control line 52) to part that should control line 52, shows that with this this test paper 51 is effective.If this no appearance of control line 52, means that this test paper 51 is invalid, no matter assay is positive or negative, and assay is all unreliable.Similarly, after use, this test paper 51, to checking the part possibility pulverize redness (occurring this check line 53,54) of line 53,54, shows that with this check is positive.And if this check line 53,54 does not occur, assay is negative.
Certainly, the concrete structure of this test paper disk 50 is not limited to present embodiment, and for example, in other embodiments, this test paper disk 50 may only have a check line and/or only have a control line.
See also Fig. 2, this test paper disk reader 60 comprises a shell 10, a printed circuit board (PCB) (printed circuit board, PCB) 23, four light sources 24,241,242,243, four photodetectors 25,251,252,253, a display 21, a position switch 28 and an indicator 22.
This shell 10 comprises a upper cover 20 and a lower cover 30, and this upper cover 20 and these lower cover 30 combinations form a host cavity 11 and by this host cavity 11 and the outer slot being communicated with 40.This PCB 23 is contained in this host cavity 11.This slot 40, to shape that should test paper disk 50, reads position thereby allow this test paper disk 50 to insert 11 to one of these host cavities from this slot 40.When this test paper disk 50 is positioned at this and reads position, this test paper disk reader 60 can read assay.This upper cover 20 also offers one first opening 12 and second opening 13.
Refer to Fig. 3, this PCB 23 comprises 26, one drivers 29 of a timing sequencer and a signal processor 27.
This timing sequencer 26 is for generating clock signal.
This light source 24,241,242,243 and this photoelectricity photodetector 25,251,252,253 are arranged on this PCB 23, wherein, this light source 24,241,242,243 is connected electrically to this driver 29, and this photodetector 25,251,252,253 is connected electrically to this signal processor 27.This driver 29 is for driving in order this light source 24,241,242,243 luminous (ginseng Fig. 4-6) according to this clock signal.
This light source 24,241,242,243 and this photodetector 25,251,252,253 arrange in pairs, and are respectively used to detect the background of this control line 52, this check line 53,54 and this test paper 51.Concrete, the light that this light source 24 sends reflexes to this photodetector 25 through this test paper 51 part corresponding with this control line 52.The light that this light source 241 sends reflexes to this photodetector 251 through this test paper 51 part corresponding with this check line 53.The light that this light source 242 sends reflexes to this photodetector 252 through this test paper 51 part corresponding with this check line 54.The light that this light source 243 sends through the background reflectance of this test paper 51 to this photodetector 253.
General, reflection of light is subject to the color of echo area and the impact of color intensity.Therefore, photodetector 25,251,252,253 can by detect this test paper 51 to should control line 52 and the reflected light of part of this check line 53,54 and the reflected light of the background of this test paper 51 between this control line 52 of diversity judgement and this check line 53,54 whether occur, even this control line 52 and this check line 53,54 quite faint in, all can produce corresponding check signal.
This signal processor 27 reads the check signal of this photodetector 25,251,252,253 and processes check signal to produce the consequential signal corresponding with assay.
This display 21 is arranged on this PCB 23 and is electrically connected to this signal processor 27, for reading result signal, and shows assay according to consequential signal.For example, if this photodetector 25,253 detect different light quantity (i.e. this test paper 51 to should the part of control line 52 and the reflected light difference of background), and the assay that this signal processor 27 produces is: this test paper 51 is effective, otherwise this test paper 51 is invalid.If this photodetector 251,252,253 detects different light quantity (i.e. this test paper 51 to should the part of p- wire 53,54 and the reflected light difference of background), the assay of this signal processor 27 is positive, otherwise negative.This display 21 exposes from this shell 10 by this second opening 13.
Preferably, this light source 24,241,242,243 adopts green LED (light emitting diode, LED), to improve check sensitivity.Concrete, with respect to the light of other wavelength, the reflectivity of green light be subject to the color of echo area and the variation of color intensity more obvious.
The quantity of this light source and photo-detector is not limited to the quantity that this embodiment adopts, and should arrange according to this test paper 51.For example, if this test paper disk 50 only has a control line or check line, this test paper disk reader 60 may only adopt two light sources and two photo-detectors, for detecting the reflected light of this control line or check line and background.
The reflected light of checking the background of this test paper 51 be for this test paper 51 to should control line 52 and the reflected light of the part of this check line 53,54 compare, a comparison basis is provided.In other embodiments, can pre-determine comparison basis and input this signal processor 27 with calculating by experiment.So, can omit for light source and the photodetector of the background of checking this test paper 51.So, if this test paper disk 50 only has a control line or check line, so only need to adopt a light source and photodetector.In this case, this timing sequencer 26 also can save.
This position switch 28 is arranged on the appropriate location of this PCB 31, makes this test paper disk 50 in the time that this reads position, and this test paper disk 50 contacts and open this position switch 28.Corresponding, this timing sequencer 26, this driver 29 and this signal processor 27 start.
This indicator 22 is arranged at this PCB 31 and is electrically connected with this position switch 28 and this signal processor 27, and exposes from this shell 10 by this first opening 12.This indicator 22 is used to indicate the duty of this test paper disk reader 60 and the effective status of this test paper disk 50.For example, in the time that this position switch 28 is opened, this indicator 22 can indicate this test paper disk reader 60 to start by first signal light (for example continuing to send ruddiness).In the time that this test paper disk 50 is invalid, this indicator 22 sends secondary signal light (ruddiness for example glimmers).In the time that this test paper disk 50 is effective, this indicator 22 sends the 3rd flashlight (for example turing green).
Please refer to Fig. 7, the diagnostic device 200 of second embodiment of the invention is basic identical with diagnostic device 100, but changes another shell 10A.This shell 10A and upper cover 20 are similar.But this shell 10A offers a locating slot 40A and reads position for locating this test paper disk 50 in this.
In a word; those skilled in the art will be appreciated that; above embodiment is only for the present invention is described; and be not used as limitation of the invention; as long as within connotation scope of the present invention, within the appropriate change that above embodiment is done and variation all drop on the scope of protection of present invention.
