The method of detection HP infection mainly has invasive and Noninvasive two major classes at present.Invasive method need to obtain group living by scope
It knits and is detected, pain is brought to tester；Noninvasive method；Using14C urea breath tests, accuracy height, hurtless measure,
Without cross-infection.Endogenous or exogenous urea can be resolved into NH by the urease that HP is generated3And CO2, CO2It is inhaled in small intestine epimere
Receive, into blood after with exhale be discharged.When inspection, tester takes orally a certain amount of14After the urea of C flag, pass through high sensitivity testing
Instrument measures in expiration14The amount of C can determine whether that whether there is or not Helicobacter pylori infections.14C is radioactive isotope, and amount of radiation is smaller,
Also there are higher safety, price more honest and cleaner.
Testee is oral14After the urea of C flag, if there are HP in testee's stomach, the urease which generates will make urine
Element resolves into14CO2.It is checked in testee's exhaled gas with helicobacter pylori tester14The amount of C, so that it may whether be felt with diagnosis
Contaminate helicobacter pylori.
Invention content
The utility model provides a kind of by the helicobacter pylori detector for the two-ways cpu licensed；Using electricity
It is measured from counting method14C, the external device for solving existing helicobacter pylori detector generally existing is few, breathing card abuse, behaviour
The problems such as it is inconvenient to make, and observation result is not intuitive, and sampling result is inaccurate.
For above-mentioned purpose, technical solutions of the utility model are as follows：
It is a kind of to be exhaled by the helicobacter pylori detector for the two-ways cpu licensed, including detecting system and human body
Harvester is inhaled, the detecting system includes Geiger tube, signal collection processing unit, data processing unit, result display unit
With verification granted unit；The signal collection processing unit is communicated with data processing unit by UART modes, data processing list
Member is connected with result display unit, and control result display unit；
The signal collection processing unit is NXP LPC1768 MCU processors, by Geiger tube14C detects signal amplification, instead
To triggering and pulse-width regulated the DPM values of detected human body respiration harvester are obtained by the pulse of acquisition by calculating；
The data processing unit is four core Cortex-A7 processors, receives the data transmitted with storage MCU processor,
And compare the range of the feminine gender and the positive where the DPM values pre-set；
The verification granted unit is that radio frequency reads and writes card module, is connected with signal collection processing unit by UART, is read
The access times information of signal collection processing unit simultaneously rewrites data, reaches and licenses number by data destroying.
Further, the result display unit is capacitance touching control display screen, including screen size is that 8 cun of resolution ratio are
1024 × 600 liquid crystal display and capacitive touch screen is connected to data processing unit by LVDS interface, IIC interfaces respectively.
Further, the data processing unit receives the information of capacitance touching control display screen, is responsible for human-computer interaction.
Further, the result display unit further includes UART 58MM thermal printers, is passed through by data processing unit
UART connections control output.
Further, the DPM values negative range is in 0-99D PM；Positive range 149-2499 DPM；And 99-149
It is uncertain value between DPM, repeatedly measurement is needed to take average result.
Further, the helicobacter pylori detector also adds 3 usb expansion interfaces, can circumscribed USB keyboard and mouse
Mark, for logging data.
Further, the human body respiration harvester is that breathing blocks, and breathing is arranged with the verification label of encryption data, exhales
Inhaling the quantity of card, with detector to license number consistent；Radio frequency reads and writes card module and reads the verification label breathed in card, obtains
The access times that detector is authorized reach detector and are matched with special breathing card, later do data in verification label
It destroys, prevents that the access times that verification label malice obtains detector are used for multiple times, also avoid to occur non-dedicated
Breathing card is detected the inaccuracy for causing detector with detector.
Advantageous effect：The utility model testing result is accurate, and display effect is more preferably；MCU processor processing detection signal leads to
It crosses UART and signal data is integrated into transmission, then handle control display through four core Cortex-A7 processors and print, compensate for signal
Collecting unit can not drive the shortcomings that high definition capacitance touching control display screen；And increase the peripheral port of USB, it is new that this practicality is significantly increased
The practicability of type.The utility model is prevented from reusing, is reached and set by the function mandate instrument access times of radio frequency read-write card
It is standby with card, specially block special, it is ensured that the normal work of detector also ensures the accuracy of data.
