Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please refer to Figure 1 , Figure 1 A flowchart illustrating a pH monitoring method provided in an embodiment of the present invention. The method may include: Step 101: Obtain the calibration parameters stored in the non-volatile memory within the pH catheter.
[0021] The calibration parameters include the zero-point potential of the pH electrode inside the pH conduit; the pH electrode uses a pre-designed composite material with stable electrochemical properties.
[0022] It should be noted that the pH catheter in this embodiment can be a catheter used to monitor the pH (Pondus Hydrogenii, acidity / alkalinity) value in the digestive tract. A pH electrode can be installed inside the pH catheter to collect pH signals, such as voltage signals (i.e., potential difference), to determine the corresponding pH value. In this embodiment, the pH electrode inside the pH catheter can be made of a pre-designed composite material with stable electrochemical properties, giving the pH electrode high stability and resistance to characteristic changes. This prevents characteristic drift during use and avoids the on-site calibration process required for traditional pH electrodes.
[0023] Correspondingly, the specific material type of the preset composite material used in the pH electrode in this embodiment can be set by the designer according to the practical scenario and user needs. For example, the preset composite material can be an antimony alloy or other types of composite materials. As long as the preset composite material can be used for pH monitoring and has stable electrochemical characteristics, this embodiment does not impose any restrictions on it.
[0024] Accordingly, a non-volatile memory (such as a pH conduit) can be provided inside the pH conduit in this embodiment. Figure 2 The memory in the system is used to store pre-set calibration parameters, such as calibration parameters obtained before leaving the factory (e.g., ...). Figure 2 This includes a factory calibration phase to avoid on-site calibration during subsequent use. For example, each pH catheter can undergo standardized and precise calibration before leaving the factory, obtaining its unique calibration parameters and storing them in built-in non-volatile memory.
[0025] The specific content and type of calibration parameters in this embodiment can be set by the designer according to the practical scenario and user needs. For example, calibration parameters may include the zero-point potential of the pH electrode inside the pH conduit. Figure 2 The unit is V (X.XXX). Calibration parameters may also include the slope of the pH electrode to further facilitate pH signal calibration and correction, ensuring accuracy. The slope includes the relationship between voltage and pH value, such as... Figure 2 The XX.XX (unit: mV / pH) indicates the relationship between voltage and pH value. When the pH catheter is also used for impedance monitoring, an impedance electrode can be installed inside the pH catheter. Calibration parameters can also include the impedance reference of the impedance electrode inside the pH catheter, such as... Figure 2 The XXXX (unit: Ω) in the figure is used to calibrate and correct the impedance signal collected by the impedance electrode, so as to realize the automatic calibration and correction of the pH value and impedance value monitored by the pH impedance joint monitoring system, thereby improving the accuracy and convenience of monitoring.
[0026] It is understood that the method provided in this embodiment can be applied to recorders that are communicatively connected to a pH catheter. The specific method by which the recorder obtains the calibration parameters stored in the non-volatile memory within the pH catheter in this step can be set by the designer according to the practical scenario and user needs. For example, when the recorder is wiredly connected to the pH catheter via a connecting cable, the recorder reads the calibration parameters through the connecting cable. For instance, after identifying the pH catheter through the connecting cable, the recorder can automatically read the calibration parameters stored in the non-volatile memory within the pH catheter to achieve automatic reading of the calibration parameters. When the recorder and the pH catheter are connected wirelessly (such as via Bluetooth), the recorder reads the calibration parameters wirelessly. This embodiment does not impose any limitations on this.
[0027] Step 102: Acquire the pH signal collected by the pH electrode.
[0028] In this embodiment, the pH signal can be the pH signal collected by the pH electrode inside the pH conduit during pH monitoring (e.g., ...). Figure 2 The data collected in real time (such as voltage signals) can be used. The specific signal type of the pH signal in this step can be set by the designer, such as using a method similar to or the same as the data acquisition method of the pH electrode in the pH conduit in related technologies. This embodiment does not impose any restrictions on this.
[0029] Correspondingly, the specific method by which the recorder acquires the pH signal collected by the pH electrode in this step can be set by the designer according to the practical scenario and user needs. For example, the pH signal can be received through a connection cable; or it can be received through wireless communication. This embodiment does not impose any restrictions on this.
[0030] Step 103: Use calibration parameters to calibrate and correct the pH signal to obtain the corrected output pH value.
[0031] It is understood that in this step, the recorder can calibrate parameters to correct the pH signal collected by the pH electrode, thereby obtaining the final accurate output pH value (i.e., the output pH value). The specific method used in this step to calibrate and correct the pH signal using calibration parameters to obtain the corrected output pH value can be set by the designer. For example, if the calibration parameters include the zero-point potential and slope of the pH electrode, and the pH signal is a voltage signal, the recorder can use the zero-point potential to correct the voltage signal to obtain the corrected voltage; based on the slope, the output pH value corresponding to the corrected voltage can be determined. This embodiment does not impose any limitations on this.
[0032] Correspondingly, when the calibration parameters also include the impedance reference of the impedance electrode inside the pH catheter, the method provided in this embodiment may further include using the impedance reference to calibrate and correct the impedance signal collected by the impedance electrode to obtain a corrected output impedance value. For example... Figure 2 As shown, the recorder can receive real-time data (pH signal and impedance signal) collected by the pH catheter via the connection cable; after calibration and correction using calibration parameters, accurate pH and impedance values are obtained, enabling real-time detection of pH and impedance values.
[0033] Correspondingly, the method provided in this embodiment may also include a process for displaying monitoring results. For example, after step 103, the output pH value may be displayed on the screen. For example, the recorder may display the output pH value and output impedance value on the screen, and may also store the output pH value and output impedance value to facilitate subsequent data retrieval and analysis.
[0034] In this embodiment, the pH electrode made of a pre-designed composite material is used in the pH catheter, which makes the pH electrode highly stable and less prone to changes in properties. By using the non-volatile memory in the pH catheter, the calibration parameters obtained by precise calibration before leaving the factory can be stored. The pH value being monitored can then be automatically calibrated using these calibration parameters, avoiding the on-site calibration process required for traditional pH electrodes, reducing the operational difficulty of digestive tract pH monitoring, and improving monitoring accuracy.
