Intelligent glucometer capable of automatically starting up by inserting test stripTechnical Field
The invention relates to an intelligent glucometer, in particular to an intelligent glucometer with an automatic starting-up plug test strip.
Background
Most of the traditional blood glucose meters on the market at present have no intelligent operation system, and the blood glucose value is calculated by collecting microcurrent signals after blood glucose test strips and blood are chemically processed. The functions are as follows: the test strip is automatically started to enter a measurement state, a small number of test results can be stored in the test strip, and a small number of test strips with communication functions such as serial ports, USB, bluetooth, WIFI and the like can be used for data such as a computer and a mobile phone. In order to measure accurately and with low cost, the traditional glucometer generally adopts a microprocessor of an ADC with integrated accuracy of more than 12 bits to collect microelectronic signals of biochemical reaction of blood sugar. The automatic start-up principle of the inserted test strip is that the test strip is provided with an inserted detection electrode and a ground electrode, and the two electrodes are in a conducting state on the test strip. The ground electrode corresponds to the ground of the blood glucose meter and the insertion detection electrode corresponds to the insertion detection pin of the blood glucose meter. The glucometer is powered on and automatically started, and is not powered off as long as the glucometer is powered on, and the glucometer does not operate to enter a sleep state for a period of time. The insert detect pin defaults to pull-up high and the micro-control sets the falling edge interrupt detect. When the test strip is inserted, the insertion detection pin is conducted with the ground and pulled down to generate a falling edge interrupt, so that the micro-controller of the glucometer is interrupted and waken up, and related works such as measurement and the like are processed.
Smartphones on the market are quite popular, annual sales volume exceeds 10 hundred million parts, and technology is quite mature. The intelligent mobile operation system (such as android and WindowsPhone, iOS) is adopted in the intelligent mobile phone, so that a user can entertain, make friends, shop and acquire information on the mobile phone, the application program is very convenient to update, and the application program developer can be convenient to continuously optimize the program. The device employing the intelligent mobile operating system is hereinafter referred to as an intelligent mobile device.
The traditional glucometer has the defects that the application software is simple, the program can not be automatically updated in a networking way, the glucometer can only be used for measuring blood sugar, the blood sugar can not be managed, and only a small amount of measurement data can be stored.
The inventor has made continuous efforts, combines traditional blood glucose meter and intelligent mobile device, designs intelligent blood glucose meter, separates the blood glucose measurement part of traditional blood glucose meter and application parts such as data management, interface display, etc., and the blood glucose measurement part adopts the design the same as traditional blood glucose meter, guarantees the accuracy of measurement. The application part can store management data in a mass manner on a system of the intelligent mobile device, meanwhile, the application can be very abundant, and the system can be continuously updated and maintained. Meanwhile, the intelligent blood glucose meter also supports automatic start-up of the test strip to enter a measurement state, and user experience is improved.
