[0016] This invention provides an electrolyte analyzer system based on dry biochemical methods, aiming to solve the problems of high cost, low accuracy, and complex use caused by traditional electrolyte analyzers that rely on wet chemical analysis methods.

[0017] like Figures 1 to 4 As shown, it includes: a system host, on which a control module, a detection module, a data processing module, and a battery module are installed; The system host has a test strip outlet 2, a test strip initial position 1, and an incubation chamber 3 arranged sequentially on its outer shell and inside. The incubation chamber 3 includes its body and a temperature module and a heating element disposed inside it. The temperature module is a temperature sensor, and the heating element can be in the form of an electric heating tube or an electric heating plate.

[0018] A sliding conveyor mechanism is installed along the path between the test strip outlet 2, the test strip initial position 1, and the incubation chamber 3, and is configured to transport the test strip. These three components are arranged in a straight line inside the main unit. A linear displacement module is also arranged along this straight path, with its free end serving as a slide table. This slide table holds the test strip and moves it between the three components. The sliding conveyor mechanism is activated by signals sent from a control module.

[0019] A sample dispensing gun 5 is configured to add a sample into the dispensing orifice; like Figure 2 and Figure 3 As shown, the detection module is configured to contact the test piece and input the detected micro-voltage signal to the motherboard of the system host. The system then... Figure 3 The hardware model shown performs test piece impedance checking. After reading the signal, the analyzer checks the sliding impedance. Switches C' and D' are interlocked. The analyzer includes three sampling relays (Na, K, and Cl) to implement the following signal processing functions in hardware: Offset check: The analyzer checks the amplifier's offset. Gain check: The analyzer checks the amplifier's gain by measuring the output voltage. Drift check: The analyzer measures the output voltage and detects abnormal output from the slider. The hardware model for test piece impedance checking is as follows: Figure 4 As shown, by applying a bias voltage to measure the impedance voltage of the test piece, it is determined whether the impedance state is incorrect, which serves as the basis for determining the validity of the test piece measurement data.

[0020] The data processing module is a small signal processing module, configured to perform calculations on the obtained micro-voltage data and obtain detection results.

[0021] In one embodiment of this utility model, the test strip is a dry biochemical electrolyte test strip, which is provided with a reference solution addition hole, a sample solution addition hole, and at least three sets of test bridges.

[0022] In one embodiment of this utility model, the test strip outlet 2 is located at the front end of the system host casing, the test strip initial position 1 is located at the internal center of the system host casing, and the incubation chamber 3 is located at the internal rear of the system host casing.

[0023] In one embodiment of this utility model, the system host is further provided with a display module, which is a liquid crystal display screen 8, and the display module is signal connected to the control module.

[0024] In one embodiment of this utility model, the system host is further provided with a communication module, which is signal-connected to the control module.

[0028] The specific structure and working principle of this utility model are as follows: It consists of a dry biochemical electrolyte test strip, a sliding conveying mechanism, an incubation chamber 3, a sample dispensing gun 5, and a system host. The test strip includes a reference liquid dispensing port, a sample liquid dispensing port, and three sets of test bridges. The sample to be tested is added to the dispensing port, and the test strip is transferred to the incubation chamber 3 via the sliding conveying mechanism for constant temperature heating. During this process, Na, K, and Cl ions in the electrolyte within the test strip electrode react chemically with the selective dialysis membrane, forming a potential difference in the test bridges. This potential difference is then transmitted to the system host via a sampling circuit and a small signal processing module. The host uses an STM32 embedded ARM chip as the processor, employing engineering application-level program libraries and DSP algorithm libraries in its software. High-speed data acquisition is achieved through DMA, realizing quasi-synchronous DFT non-integer correction. The sliding conveying mechanism is used to move the reagent strip to the testing position and, after testing, to the disposal position, then transports the reagent stage back to its initial position. The detection module contacts the reagent strip and inputs the detected micro-voltage signal to the main board. The data processing module performs a series of calculations on the obtained micro-voltage data to obtain the detection result. The control module is used for transmitting drive signals for the transmission mechanism, constant temperature heating drive signals for incubation chamber 3, data detection, processing, transmission, and external peripheral interfaces such as fans.
