[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.
[0024] Please refer to Figs. 1-2 The present application provides a clamping type visual bird egg potential detection storage instrument, characterized by comprising a shell 1, a clamping mechanism, a signal processing and storage unit, and a power supply unit.
[0025] The clamping mechanism comprises at least two pairs of symmetrically arranged clamping jaws 2, clamping jaw rods 3 and handles 4; the clamping jaw 2 is hinged to the front end of the shell 1, and the distal end thereof is provided with a suction electrode 6 on the inward side; the front end of the clamping jaw rod 3 is movably connected to the inner side of the clamping jaw 2 through a slot slide, and the rear end thereof extends into the handle 4; the handle 4 is movably inserted into the upper end of the shell 1, and when a user pulls the handle 4 backward, the clamping jaw rod 3 is driven to move linearly backward, and the two clamping jaws 2 are forced to close inward to clamp the bird egg through the inclined surface or lever structure, and the suction electrode 6 is in close contact with the surface of the eggshell;
[0026] The signal processing and storage unit is built in a circuit board, which is fixedly installed in the inner cavity of the clamping jaw rod base 7 in the middle part of the shell 1; the circuit board is integrated with an MCU, a signal conditioning chip, a TF card seat and an OLED display screen; one pair of suction electrode 6 at the end of the clamping jaw 2 is used as a positive and negative electrode to obtain an electrical signal, and the other pair of suction electrode 6 at the end of the clamping jaw 2 is used as a ground terminal to remove noise, and the other is only used as a fixed terminal; the suction electrode 6 used as the positive and negative electrode to obtain the electrical signal is connected with the input end of the signal conditioning chip through a wire; the output end of the signal conditioning chip, the TF card seat and the OLED display screen are electrically connected with the MCU respectively;
[0027] The power supply unit is a battery compartment 8 arranged in the handle 4, which is used for power supply of the whole instrument.
[0028] The working principle and use process of the present application are as follows: when the device is used, the shell 1 is printed by PLA, which aims to control the cost while ensuring the strength of the whole instrument, and to protect the internal battery, MCU and the like; the whole instrument is fixed by holding the shell 1 with the palm of the user, the opening and closing of the clamping jaw 2 is realized by controlling the position of the handle 4, and the shell 1 has a slot corresponding to the clamping jaw 2 for fixing the clamping jaw. At the same time, the contact points of the clamping jaw 2 and the shell form a hinged rotating structure, the clamping jaw 2 is pulled by the handle 4 to move up and down on the inside to control the turning of the clamping jaw 2, so as to realize the change of the opening and closing state of the clamping jaw. At the same time, a 0.96-inch OLED display screen is arranged on the side of the shell 1 to accurately display the ECG potential state of the target.
[0029] The clamping jaw rod base 7 is the most important unit for protecting electronic components of the whole instrument, and is also the center of data processing and storage, which is built-in with a button cell, an MCU, an AD8232 and a circuit board connected to the suction electrode 6 at the end of the clamping jaw 3 through a wire. At the same time, the base also contains an integrated power circuit, a level conversion, a pull-up resistor and a TF card seat, and uses a FATFS file system and a digital signal processing (DSP) algorithm for secret storage of experimental data for subsequent long-term observation and experiment. In order to replace the TF card conveniently and quickly, a TF card interface is arranged at the rear end of the clamping jaw rod base, which is connected with the SPI interface of the STM32F103 to transfer the ECG data.
[0030] Among them, the suction electrode 6 at the end of one pair of clamping jaws 2 respectively serves as the positive and negative electrode to obtain electrical signals, and the suction electrode 6 at the end of the other pair of clamping jaws 2 serves as a ground terminal to remove noise, and the other only serves as a fixed terminal without electronic components inside. The suction electrode 6 as the positive and negative electrode is connected with the MCU built in the clamping jaw rod base 7, so that the silver oxide flexible electrode is connected with the AD8232, realizing information transmission and 3.3V power supply of the electrode. The suction electrode 6 is the most important structure for fixing the bird egg, and the arc-shaped structure ensures the rigidity of the clamping jaw 2 to prevent damage to the bird egg caused by breakage. The front-end silver oxide flexible electrode is a kind of flexible Ag / AgCl quasi-reference electrode with nano-silver dendrite semi-embedded in the PDMS matrix, which has an ultra-long service life (30 days of continuous operation), excellent mechanical flexibility and electrochemical stability, and is suitable for EEG, ECG monitoring and H2O2 sensing. It combines the excellent electrochemical stability of silver chloride and the mechanical flexibility of the substrate. In order to increase the contact area with the bird egg, the silver chloride flexible electrode adopts a suction cup structure, which makes the bird egg more stable.
[0031] Significant cost reduction: Traditional 12-lead medical ECG devices cost tens of thousands or even hundreds of thousands of yuan, while the core components of the system (STM32F103, AD8232, OLED screen, TF card module) are all consumer-grade electronic components, and the total cost can be controlled within a very low range. This cost advantage makes large-scale deployment, personal ownership or as a disposable teaching tool possible, greatly reducing the threshold for egg monitoring.
[0032] Convenience of use and revolutionary expansion of scenarios: The device is small and easy to carry, allowing users to take it to different places such as the wild, breeding farms or laboratories for real-time detection. The operation process is extremely simple, only requiring a single hand to hold the shell and control the opening and closing of the clamping jaw 2 by pulling the handle 4 with the fingers, easily achieving bird egg clamping and electrode adhesion. This design not only eliminates the dependence on fixed electrodes and conductive gel of traditional devices, but also avoids the problem of tedious operation caused by electrode position adjustment. At the same time, the device is designed wirelessly, without the need for external power supply or data line, truly realizing portable, unbound detection and data collection anytime and anywhere, providing great convenience for poultry breeding, embryology and endangered bird protection research.
[0033] Users can regularly collect their own ECG data and store it in the TF card, generating a long-term bird egg growth archive. At the same time, the TF card can provide extremely strict protection for related data to prevent experimental data leakage. The exported standard data format (such as CSV) can be easily imported into professional software (such as MATLAB, Python Pandas, or even Excel) for in-depth retrospective analysis, statistics and visualization, and also serves as a source of raw data for scientific papers, ensuring their authenticity and traceability.
[0034] The real-time waveform visualization function displays the electrocardiogram (ECG) signal of the attached bird egg on an OLED screen, making the monitoring process more intuitive and efficient. This function can provide real-time feedback on the physiological state of the bird egg, providing experimenters with a clear and dynamic view of signal changes. This not only significantly improves the reliability and interpretability of monitoring results, but also lays a solid technical foundation for subsequent expansion of functions such as waveform analysis, data backtracking, and intelligent diagnosis.
