Background technology
Along with the living standard of people improves constantly, occur many " rich man's disease ", as diabetes, high fat of blood etc. disease. blood-sugar content weighs one of healthy important indicator, particularly for diabetes patient, keeps the important indicator of stable disease especially.The measurement of blood sugar can be measured by having wound and noninvasive mode, and have wound mode to be by puncturing human epidermal, draw blood, directly analyzes blood sugar; Non-invasive manner utilizes the glycan molecule in subcutaneous interstitial fluid, and human body is to the spectrum analysis of near infrared ray, middle infrared (Mid-IR) or far infrared, and the modes such as the radio-frequency (RF) impedance of human body are tested.Because noninvasive blood-sugar content accuracy is not high, wound formula blood glucose meter is therefore had to be the blood glucose monitoring device of main flow.
A typical electronic blood-glucose meter, is completed the analytical calculation of the blood glucose value of core by blood sugar monitoring module and its built-in single-chip microcomputer.This structure, seems simple, but there is a lot of problem:
(1) present most of blood glucose meter self-contained data line, so that be connected transmission data with computer, but
The volatile vulnerability of data line, feature causes the inconvenience of use easily not in addition.
(2) some blood glucose meter uses wireless network transmissions data, or transmits data by short message mode,
This all causes high use cost.
(3) but, in prior art, medical instrumentation bluetooth is as means of communication, could use, manually disconnect again after having communicated after needing artificial pairing, still cannot realize data easily and transmit.
(4) along with the appearance of NFC, increasing medical measurement instrument supports NFC communication function now, has therefore carried out huge facility to output transmission.
Although have at present and utilize NFC technique to carry out bluetooth to match rapidly the blood glucose meter of transmission blood glucose meter test data, but this blood glucose meter necessarily requires to be provided with NFC module in the equipment at bluetooth place, and NFC module can be communicated by CPU with bluetooth, and current most of bluetooth equipment does not install NFC communication module, this makes the communicating requirement of this device harsher, and cost is higher.
The medical equipment that current more equipment carries NFC communication function uses Felica agreement, and this has higher requirement to the protocol compatibility reading chip, cannot other NFC chip compatible.

Beneficial effect
The utility model provides the blood glucose meter that a kind of NFC of support swipes the card, and comprises blood glucose meter body, function button, blood sugar test paper, blood sugar probe, blood glucose sensor, amplifying circuit, filtering circuit, display screen, microprocessor, supply module, NFC module and antenna; Function button to be arranged on blood glucose meter body and to be connected with microprocessor; Blood sugar test paper, blood sugar probe, blood glucose sensor, amplifying circuit are connected successively with filtering circuit, complete the collection of blood glucose signal; Described filtering circuit, display screen, NFC module and antenna, supply module are all connected with microprocessor; It is characterized in that, described NFC module is dynamic N FC interface answering machine RF430CL330H.This NFC module energy compatibility most NFC chip on the market, reduces the cost of blood glucose meter.
(1) use short-distance wireless communication technology NFC, make data transmit simple and fast, only need near card reader or support that NFC smart mobile phone can transmit data.
(2) have employed wireless connections external unit, make this product to store mass data.
(3) owing to adopting NFC wireless communication technology, therefore this product power consumption is lower, and anti-interference is stronger, without the need to pairing connected mode more convenient.
(4) compared with Bluetooth technology, this product wireless transmission departmental cost is very cheap and connection establishment is fast, security is high.
(5) power consumption is lower.After increasing NFC module, power consumption increases hardly, and this is just for portable set provides more lasting flying power.
