A blood glucose meter test strip identification method

Abstract

The invention discloses a glucometer test strip recognition method. The glucometer test strip recognition method comprises: acquiring N sampling data according to time in sequence; comparing two sampling data of adjacent time points to obtain (N-1) comparing results; if the former data is greater than the later data, recording the data as first pre-set values; if the former data is smaller than the later data, recording the data as second pre-set values; if the former data is equal to the later data, recording the data as third pre-set values; summarizing an initial value M and the (N-1) comparing results and accumulating a plurality of first pre-set values, second pre-set values and third pre-set values to obtain a calculated value Z; solving a difference value between the initial value M and a trend value W and comparing the difference value with the calculated value Z; if the calculated value Z is greater than the difference value, recognizing as a simulated test strip. In a process of adopting a trend method to recognize, influences caused by factors including blood glucose concentration and the like are eliminated, and a recognition error caused by different concentrations is effectively avoided. In a calculation process, the sampling data is not calculated and an interference signal can be filtered very well; even if an interference source exists and the sampling data jumps, a final recognition result is not influenced.

Description

technical field [0001] The invention relates to the technical field of blood glucose meter testing, and further relates to a method for identifying test strips of a blood glucose meter. Background technique [0002] There are two types of test strips used in blood glucose meters, one is a simulated test strip and the other is a real test strip. The registration verification of blood glucose meters requires the use of simulated test strips, which are pure resistance test strips; while in the actual blood glucose testing process, real test strips are used to draw samples and then used in conjunction with the instrument. For two different test strips (simulated test strips and real test strips), the blood glucose meter adopts two different calibration parameter systems to achieve accurate verification or testing. In order to eliminate the interference of other external factors during the verification or testing process, the instrument needs to identify whether the simulated te...

Problems solved by technology

[0004] The above identification method has a big defect: in the actual test process, because the actual blood sugar is obtained for phase difference comparison, the blood sugar value obtained due to the influence of different factors such as blood sugar concentration, temperature or hematocrit may have a large deviation. The maximum or minimum values ​​are inaccurate sampling data; similarly, if a simulated test strip is inserted, if there is an interference source during the measurement process, it will cause a large jump in the sampling value, resulting in inaccurate identification results

The blood glucose meter needs to be used in many occasions. This identification method has limited anti-interference ability, and the identification rate is low under strong signal interference.
