in this embodiment, in combination with the description of the device and the test strip for judging the sample suction of the test strip in fig. 1 to fig. 11, when the test strip is inserted, the voltage obtaining module obtains the initial voltage value of the test strip interface
1302. When the test strip sucks a sample, the voltage acquisition module detects a real-time voltage value of the test strip interface in real time;
in this embodiment, when the test strip sucks a sample, the voltage acquisition module detects the real-time voltage value of the interface of the test strip in real time, and when the test strip is full, the equivalent internal resistance value is obtained
Then the test strip is full of voltage
1303. And the processing module judges whether the test strip is full of sample suction according to the initial voltage value and the real-time voltage value.
In this embodiment, the following concrete steps are performed:
the processing module judges whether the real-time voltage value is changed compared with the initial voltage value or not;
if yes, determining that the test strip is full of sample;
if not, determining that the test strip is not full of the sample.
If the interface voltage value is changed from V1 to V2, the test strip is determined to be full, and a full prompt message can be sent at the moment to prompt a person to stop dropping samples;
if the interface voltage value is not changed from the test strip insertion voltage value V1 to the test strip full suction voltage value V2, the test strip is determined to be not full, and at the moment, an under-full prompt message can be sent to prompt personnel to continue dropping the sample until the test strip is full.
In the above devices for identifying a test strip inserted bar, the device for judging the sample suction of a test strip and the method thereof according to all the embodiments, the present invention specifies that the identification of the inserted bar utilizes the interface voltage value as the power voltage value VCC when the test strip is not inserted, and the equivalent internal resistance of the test strip reduces the interface voltage value when the test strip is inserted, so that whether the test strip is inserted or not can be determined according to the change of the interface voltage value. The sample sucking judgment is to utilize the fact that the equivalent internal resistance value of the test strip is larger than that when the sample sucking is full when the sample sucking is not full, so that the interface voltage value when the sample sucking is not full is larger than that when the sample sucking is full, and determine whether the sample sucking is full by judging the change of the interface voltage value. Therefore, the cutting identification and the sample suction judgment can be realized through the interface voltage value.
