Method, in particular to one kind are built in intelligent water toilet pan and to extend to excreta with photoelectricity and mechanical structure water-soluble
Carried out in liquid in automatic detection excreta aqueous solution whether the health supervision type intelligent closestool device containing occult blood signal and its latent
Blood detection method.
Background technique
According to National Cancer Institute, in the U.S., colorectal cancer number of the infected accounts for the 8% of overall pathogenesis of cancer number, occurs
Rate occupies the 4th, and the death rate occupies second.In China, colorectal cancer number of the infected accounts for the whole world 18.6%, and death toll accounts for full generation
Boundary 20.1%, two rank first in the world.Therefore, the prevention and treatment for carrying out colorectal cancer in China, has world significance.
The initial stage symptom of cancer of colon is fecal occult blood, and the initial stage symptom of bladder cancer and carcinoma of ureter is urine occult blood,
Therefore, detection Faecal occult blood becomes one of the important key technology of disease prevention.Existing occult blood detection method is using immune
The detection of method occult blood, is primarily present following problems and disadvantages: first is that must voluntarily acquire an excrement specimen, then return hospital etc. and is to be tested
As a result, losing quick and convenience, unnecessary trouble is brought to detection；Second is that about 1 gram is only acquired when an acquisition excrement specimen,
It having arrived after hospital, hospital, which is used only wherein, only to test for about 6 milligrams, since occult blood is in excrement and non-uniform Distribution,
It is easy to generate under-referral because occult blood is not acquired in checkout procedure, reduces detection efficiency, and detection effect is poor；Three
Tumour or polyp sheet as intermittent bleeding episodes, not continuous bleeding, it is also possible on the day of an acquisition excrement specimen or
There is no bleedings for the previous day, tumour or polyp, and causing inspection result is under-referral, reduces detection efficiency, and detect effect
Fruit is poor.In addition, notification number is CN104254621A, Chinese utility model patent disclosed on December 31st, 2014 discloses one
The device and method of kind telemetering human faecal mass and the blood in urine, the device and method are primarily present following problem: on the one hand, must

1 top of object aqueous solution, then the second microcontroller 31 sends out trigger signal to occult blood detection module 2；
Step 4: occult blood detection module 2 receives the trigger signal sent from the second microcontroller 31；
Step 5: trigger signal elder generation activating light source 21, light source 21 launches the light beam of specific wavelength again, and light beam injects horse again
In excreta aqueous solution 1 in bucket 5 and backlight is generated, then backlight injects optical sensor 22, and optical sensor 22 connects
It receives backlight and the backlight received is transmitted to the first microcontroller 23；Wherein, light source is LED light source or laser；If
Light source is the laser diode for launching 407nm wavelength light beam, and the range of driving current is set as 20-140mA, when detect weight
When the fluorescent signal and fluorescence spectrum peak value of the excreta aqueous solution that amount percentage concentration is 0.4% are about 620nm, detection is dived
Blood signal, thus realize in excreta whether the detection function containing occult blood signal；If light source is to launch 407nm wavelength
The laser diode of light beam, driving current are set as fixed current value 20mA, when the range for detecting concentration expressed in percentage by weight is
When the fluorescent signal and fluorescence spectrum peak value of the excreta aqueous solution of 0.01-0.4% are about 620nm, detection obtains occult blood signal,
To realize in excreta whether the detection function containing occult blood signal；Basic testing principle of the invention is to measure blood
Fluorescence actually should not only be defined in Blood fluorescence certainly, but the absorption for measuring the general spectrum of blood, reflection contain
The spectral characteristics such as scattering and Raman, all can be used as the foundation of detection excreta aqueous solution occult blood；
Step 6: the first microcontroller first carries out signal to the optical signal of backlight and is converted into electric signal, then by electric signal
It is converted into digital signal, then data processing is carried out to digital signal, then whether judge in excreta containing latent according to data processing
Blood signal simultaneously obtains testing result, then will test result and is sent to intelligent water toilet pan；
Step 7: the second microcontroller receives testing result signal and will test consequential signal and sent by display interface
To display device, display device will test to be come out as the result is shown, to terminate to detect.
Embodiment 2:
Health supervision type intelligent closestool device, as shown in Fig. 2-8,10, difference from Example 1 is only that:
