Description
Technical field
The invention belongs to medical instruments field, particularly a kind of measurement of blood sugar level and display device.
Background technology
Traditional blood glucose measuring device, no matter be to adopt light intensity determination method, electrochemical determination or other mensuration mode, mostly be to adopt digital mode to show the blood sugar measured of people, as, directly demonstrate the blood glucose concentration value that measurement result obtains in the display screen part of measurement mechanism.Because most of user is the diabetic who needs close attention self blood sugar level, to proving installation directly demonstrated blood sugar measured also need with the blood sugar diagnostic criteria in standard value compare, which stage, whether the blood glucose value that can draw self normally reached belonged on earth.Thus, the people less for some medical knowledges, that professional ability is lower then needs to spend more time and efforts and is used for behind each blood glucose measurement measured value and standard value being compared, to judge the true horizon of self blood sugar.Therefore existing blood glucose measuring device uses complicated, and efficient is lower, the judgement that may make the mistake and delay treatment opportunity or carry out wrong treatment.
Summary of the invention
Whether normally the objective of the invention is to overcome the deficiencies in the prior art, providing a kind of can directly judge contrast with standard value with the measurement result of blood glucose value, thereby draw the blood glucose value measurement and the display device of blood sugar level.
A kind of measurement of blood sugar level and display device, constitute by housing and the control circuit that is installed in the housing, housing is provided with LCD display and testing jack, control circuit in the housing is by CPU, crystal oscillator, power circuit, operational amplifier, storer, temperature element and low voltage detecting module constitute, wherein, the special purpose interface of CPU is connected with crystal oscillator and power circuit, the I/O interface of CPU respectively with storer, LCD display, operational amplifier, temperature element and low voltage detecting module are connected, the other end of the operational amplifier test paper interior with inserting testing jack is connected, and it is characterized in that: be provided with a status display strip on the LCD display on the housing.
And, on housing, be provided with and the corresponding contrast bar of described status display strip.
And described status display strip is one group and shows block, and described contrast bar is one group of contrast stick that is provided with distinct color, and this contrast stick is corresponding one by one with demonstration block on the status display strip.
And described contrast bar is two groups, and these two groups contrast bars are respectively arranged with the contrast stick of distinct color.
And described storer is an eeprom memory.
Advantage of the present invention and good effect are:
1. the LCD display of this device not only can show the concrete numerical value of measurement result of blood glucose value, also be provided with the status display strip in a demonstration residing level stage of blood glucose value, this status display strip is made of a plurality of demonstration blocks and is horizontally placed on bottom the LCD display, its pairing blood sugar level increases from left to right gradually, and the tester can find out self blood sugar level present stage this moment intuitively.
2. this device is gone back correspondence and is provided with two groups of contrast bars on housing below the status display strip on the LCD display, be respectively fasting blood glucose level contrast bar and level of postprandial blood sugar contrast bar, on this contrast bar respectively by with the demonstration block of status display strip one to one the contrast stick of different colours whether identify blood sugar level normal, this color is by one group of standard value blood sugar level to be divided into three kinds of stages, adopts green, yellow and redness is represented normal level respectively, undesired level (blood glucose value is crossed low or is in critical conditions) and diabetes level (blood glucose value is higher).So, the tester can find out more intuitively by comparative observation whether self blood sugar level is in normal condition, thus symptomatic treatment more accurately and timely.
3. this device can also carry out record to test result by eeprom memory, so that carry out the contrastive detection of certain hour section.
4. scientific structure design of the present invention is reasonable, easy to operation; Except that demonstrating the blood glucose value, can also judge the residing blood sugar level stage of this blood glucose value, make the user accurately and timely self blood glucose condition be monitored, whether the blood sugar level that is well understood to self more is normal, provides foundation for the user in time makes treatment or seeks medical advice according to the situation of self.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
Measurement of this blood sugar level and display device, constitute by housing 6 and the control circuit that is installed in the housing, housing is provided with LCD display 1 and testing jack 5, this testing jack can insert with test paper for test, and this test is connected with control circuit by a linker that is provided with in testing jack with test paper.Control circuit in the housing is connected and composed by CPU, crystal oscillator, power circuit, operational amplifier, storer, temperature element and a low voltage detecting module, wherein, the special purpose interface of CPU is connected with crystal oscillator and power circuit, the I/O interface of CPU is connected with storer, LCD display, operational amplifier respectively, the other end of operational amplifier is connected with the interior a connector installed of testing jack, and this connector can link to each other with the test paper of slotting testing jack.The I/O interface of CPU also connects a temperature element and a low voltage detecting module respectively, calculates needed measurement temperature value of blood glucose value and magnitude of voltage for CPU provides.This device is to adopt electrochemical method measuring blood value, chemical constitution on the test paper (biology sensor) and the glucose in the blood sample react, produce current signal, this signal amplifies by operational amplifier and is transferred to CPU, and CPU obtains raw data by sampling, and raw data is calculated according to the program that is provided with, obtain corresponding blood glucose value, and the territory, digital display area that this measured value exports LCD display to is shown, transfer to storer simultaneously and store.
The innovative point of this device is: be provided with a status display strip 2 on the LCD display on the housing, status display strip is horizontally placed on the bottom of LCD display in the present embodiment, also can be arranged at any suitable location of LCD display.As a kind of optimal way, status display strip is one group and shows block, comprise that six show block, each shows the corresponding blood sugar level of block, this blood sugar level is to divide according to the diabetes diagnosis standard of the blood sugar diagnostic criteria of The World Health Organization's announcement and WHO, IDF proposition in 1999, sees Table 1.Certainly status display strip also can be other form and represents blood sugar level, as one group of status display strip that increases gradually etc.CPU judges by blood glucose value and the blood sugar standard value that will record, judgment result displays in this show bar, is shown as the bright or flicker of demonstration block, is the observation habit that adapts to people, the blood sugar level of this show bar correspondence also can be inverted certainly for increasing gradually from left to right.
The deterministic process process flow diagram of CPU as shown in Figure 3.
