Biological sensing device capable of detecting strip code and insufficient filling of sample

Abstract

The invention relates to a biological sensing device capable of detecting a strip code and insufficient filling of a sample, comprising a biological sensing strip and a processing and displaying unit. The biological sensing strip is provided with a first recognition membrane, a second recognition membrane, a third recognition membrane and a code sensing resistor, wherein the three recognition membranes can have an electrochemical reaction with a sample to be tested and a resistance value of the code sensing resistor can represent a strip code of the biological sensing strip. The processing and displaying unit comprises a first readout circuitry and a second readout circuitry, wherein the first readout circuitry can read a resistance value of the code sensing resistor to enable the strip code corresponding to the resistance value to be obtained automatically by the processing and displaying unit and can detect whether the sample to be tested has fully covered the first recognition membrane and the second recognition membrane so as to confirm whether the sample injected into the biological sensing strip is sufficient, thereby enabling the processing and displaying unit to accurately calculate a sample magnitude of an examinee.

Description

technical field [0001] The present invention relates to a biosensory test piece and its display processing device, in particular to a biological sensor with a detectable test piece code that can automatically detect the test piece code and detect whether the filling amount of the sample is sufficient and whether the sample filling is insufficient. sensing device. Background technique [0002] Due to the rapid development of sensor technology in recent years, various biosensors using enzyme redox reactions have been continuously proposed and introduced one after another. Among them, the biosensors in the field of biomedicine have the most types. For example: blood sugar sensor, which can be used to check the blood sugar content in the blood, therefore, the blood sugar sensor has become an important device for self-inspection of diabetic patients, which can help diabetic patients self-detect the concentration of blood sugar content in the body, so that diabetic patients Can p...

Problems solved by technology

[0006] 1. The test piece code of the blood sugar test strip cannot be automatically detected. When diabetics use the existing conventional blood sugar sensing device, they must first input the test piece of the blood sugar test strip before the blood drips into the reaction layer However, once the patient enters the test strip code incorrectly, it will inevitably affect the accuracy of the processing and display unit to calculate the blood glucose concentration in the blood. In severe cases, the patient will misjudge his own diabetes illness, and regrettable incidents

[0007] 2. There is no device or mechanism to automatically detect whether the blood completely covers the reaction layer. If the blood does not completely cover the reaction layer, it means that the amount of blood injection is insufficient, which will inevitably affect the accuracy of the processing and display unit to calculate the blood sugar concentration.

[0009] It can be seen that the above-mentioned existing biosensor test strip and its display processing device obviously still have inconvenience and defects in structure and use, and need to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
