It crosses display screen to show, patient presses control button 8 and confirms；Then program is transferred to content measurement process, and radiation source 3 is logical at this time
Electricity, it is infrared by positive lens 7 radiation enter monochromatic component, in monochromatic component spectroscope 5 light splitting and stationary mirror 4 and
Under the collective effect of mobile mirror 6, the monochromatic wavelength in spectral coverage is successively decomposed by wavelength, monochromatic infra-red radiation successively irradiates sample
On product room, due to sample room light-permeable, on monochromatic light exposure to food, the carbohydrate content information back reflection of food is carried
Light enters infrared detector, and infrared detector carries out photoelectric conversion, and the electric signal of generation enters amplification module, and electric signal is through amplifying
It is successively filtered afterwards by filter module and carries out analog-to-digital conversion with analog-to-digital conversion module, finally reach processor, processor root
Calculation process is carried out according to electric signal and weight value, to calculate the total amount of the carbohydrate of food, and passes through display screen display
Show.
The present apparatus uses infrared spectrometry technology, without handling non-measured composition removal, ensure that the original of food
It is stateful not to be changed, thus food nutrition is not influenced, and food is not contacted with other parts, it will not be caused to food
New pollution, user are more willing to accept.In measurement process, without consuming measurement material or reagent, measurement cost is reduced, originally
Invention device production is simple, easy to use, is very beneficial for the popularization in market.In addition, the result precision measured after mixing is high,
And technical difficulty is small, it is easy to accomplish.
Embodiment two
As shown in Fig. 2, the measurement method based on above-mentioned carbohydrate intake damage-free measuring apparatus, including following step
It is rapid:
After S1, vortex mixer mix food to be measured, the weight value of food after mixing is obtained by electronic scale；
S2, radiation emission wide spectrum infrared light be irradiated on food after monochromatic component becomes monochromatic light；
S3, monochromatic light are through on food absorption back reflection to infrared detector, infrared detector converts the optical signal of acquisition
After electric signal, electric signal is sent to processor；
S4, processor calculate the carbohydrate total amount of dietary intake according to weight value and electric signal, and by carbon hydrate
Object total amount is shown on a display screen.
The above method guarantees original shape of food without removing non-measured composition by using infrared spectrometry technology
State is not changed, and does not influence the nutrition of food, is not necessarily to consume measurement material or reagent in measurement process, is reduced measurement cost,
And food is not contacted with other parts, it is ensured that food will not pollute, easy to use, be conducive to the popularization in market.
It is to be illustrated to preferable implementation of the invention, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
