Description

Technical Field

[0001] The invention relates to the field of medical auxiliary equipment, and in particular to a multifunctional gastric tube capable of monitoring intragastric pressure and pH value in real time. Background Art

[0002] In the medical field, gastric tubes are widely used in the diagnosis and treatment of digestive system diseases. The main function of traditional gastric tubes is to drain gastric contents or infuse nutrient solution, which is achieved through manual operation or simple mechanical devices. However, their functions are relatively simple and cannot meet the complex needs of real-time monitoring of the gastric environment.

[0003] With the continuous advancement of medical technology and people's increasing attention to health management, real-time monitoring of intragastric pressure and pH value has become increasingly important. Intragastric pressure and pH value are important indicators reflecting the state of gastric function. By monitoring these data in real time, doctors can more accurately evaluate patients' digestive function, diagnose related diseases (such as gastroesophageal reflux disease, gastric ulcer, etc.), and adjust treatment plans in a timely manner, thereby improving treatment effects and patients' quality of life.

[0004] However, existing gastric tube products still have many deficiencies in terms of real-time monitoring function, fixation method, and intelligence level. For example, although some gastric tubes can monitor intragastric pressure, they cannot monitor pH value at the same time, which makes it impossible for doctors to obtain comprehensive gastric function data; in terms of fixation method, the traditional bundling or pasting method not only has limited fixation effect, but is also prone to cause the catheter to shift or fall off due to patient activities, and may also cause discomfort and skin damage to patients; in addition, the existing gastric tubes are relatively backward in intelligence and cannot be adjusted intelligently according to the actual situation of the patient, such as automatically adjusting the monitoring frequency and alarm threshold, which limits their effectiveness in clinical applications.

[0005] Therefore, in view of the shortcomings of existing technologies, it is necessary to develop a multifunctional gastric tube that can simultaneously monitor intragastric pressure and pH value, has a stable and reliable fixation method, and is highly intelligent to meet the needs of clinical diagnosis and treatment. Summary of the invention

[0006] To solve the above problems, the present invention provides a multifunctional gastric tube that can monitor the intragastric pressure and pH value in real time. It not only has the real-time monitoring function, but also adopts an intelligent fixing component, which can realize the intelligent fixation and relaxation of the catheter, thereby improving the comfort and safety of the patient.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a multifunctional gastric tube capable of real-time monitoring of intragastric pressure and pH value comprises a catheter, and also comprises a monitoring component for monitoring intragastric pressure and pH value, a power component and a fixing component for providing power to the monitoring component, wherein the monitoring component is electrically connected to the power component, the monitoring component and the power component are both mounted at one end of the catheter, the fixing component is detachably connected to the catheter, the fixing component comprises a nose bracket, a binding component for fixing the nose bracket on the patient's head and a locking component for fixing the catheter are mounted on the nose bracket, the locking component comprises an outer shell and an inner shell, an installation chamber is provided between the outer shell and the inner shell, a driving component is fixedly connected in the installation chamber, an output shaft of the driving component is coaxially fixedly connected with a driving gear, the driving gear is meshed with a gear ring, the gear ring is rotationally matched with the inner side wall of the inner shell, the gear ring is meshed with a plurality of driven gears, the driven gear is rotationally connected with the inner side wall of the outer shell, a spiral groove is provided on the side of the gear ring away from the driving gear, a plurality of fixing plates are slidably matched in the spiral groove, and the fixing plates are distributed along the circumference of the gear ring; A trigger is installed on one side of the fixing plate. The trigger is used to monitor the pulling force on the catheter caused by the patient's own activities and the pressure on the catheter caused by the fixing plate. The trigger signal is connected to the controller. When the real-time tension data monitored by the triggering member exceeds the tension threshold, the controller sends a fixing instruction to the driving member, and the driving member operates to make the fixing plate tighten the fixation of the catheter; When the real-time pressure data monitored by the triggering member exceeds the pressure threshold, the controller sends a loosening instruction to the driving member, and the driving member operates to cause the fixing plate to loosen the fixation of the catheter.

[0008] The technical principle of the above solution is as follows: The monitoring component is located at one end of the catheter and can monitor the pressure and pH value in the stomach in real time. These data are of great significance for evaluating the patient's digestive function and diagnosing related diseases. The power supply component provides stable power support for the monitoring component to ensure the continuity and accuracy of the monitoring data.

[0009] As the core part of the fixing assembly, the nose bracket is fixed to the patient's head through a binding piece to provide stable support. The locking piece includes an outer shell, an inner shell, a driving piece, a driving gear, a ring gear, a driven gear and a fixing plate. The spiral groove design of the ring gear enables the fixing plate to slide on the circumference of the ring gear, thereby fixing or loosening the catheter. The trigger on the fixing plate can monitor the tension and pressure of the catheter in real time. When the catheter is subjected to tension or pressure, the trigger will detect these changes and transmit the signal to the controller. According to the preset tension threshold and pressure threshold, the controller issues instructions to the driving piece to enable the fixing plate to fix or loosen the catheter.

[0010] The above scheme has the following beneficial effects: 1. Compared with the traditional gastric tube in the prior art, this solution provides more accurate and comprehensive data on the patient's digestive status by real-time monitoring of intragastric pressure and pH value. This helps doctors to more accurately evaluate the patient's digestive function, timely discover and deal with potential digestive problems, thereby improving treatment effects and the patient's quality of life.

[0011] 2. The fixing components in this solution are cleverly designed, especially the locking part, which realizes intelligent fixation and relaxation of the catheter through the coordinated action of the driving part, the active gear, the gear ring, the driven gear and the fixing plate. This design not only improves the stability of the catheter and reduces the risk of catheter displacement or falling off due to patient activities, but also realizes dynamic adjustment of the catheter fixation state through real-time monitoring of the trigger and intelligent control of the controller, thereby ensuring the comfort and safety of the patient.

[0012] 3. Compared with the fixing methods in the prior art, the fixing components in this solution are more flexible and intelligent. Traditional fixing methods often use simple bundling or pasting, which not only have limited fixing effects, but also easily cause discomfort to patients. The fixing components in this solution can automatically adjust the position and state of the fixing plate according to the tension and pressure on the catheter, thereby realizing intelligent fixation and relaxation of the catheter, improving the patient's comfort and user experience.

[0013] 4. The multifunctional gastric tube in this solution is also easy to maintain and replace. The fixed component and the catheter are detachably connected, so that medical staff can easily replace damaged parts or clean and disinfect the entire gastric tube, thereby ensuring the hygiene and durability of the equipment. At the same time, this design also reduces the maintenance cost and difficulty of use of the equipment, allowing more patients to benefit from this advanced medical device.

[0014] Furthermore, the monitoring component includes a first pressure sensor, a pH sensor and a temperature sensor. The first pressure sensor is used to monitor the pressure changes in the stomach in real time, and convert the pressure signal into an electrical signal and output it to the controller. The pH sensor is used to measure the pH value of gastric fluid, and convert the measured pH value into an electrical signal and transmit it to the controller. The temperature sensor is used to monitor the temperature data in the stomach, and convert the temperature data into an electrical signal and output it to the controller. The controller judges the intragastric pressure data, the pH value of gastric fluid and the intragastric temperature data. When the controller judges that any one of the intragastric pressure data, the pH value of gastric fluid or the temperature exceeds the threshold, a warning message is issued to the medical staff.

[0015] Beneficial effects: The monitoring component integrates the first pressure sensor, pH sensor and temperature sensor, which can monitor the pressure changes in the stomach, the pH value of gastric fluid and the temperature data in the stomach in real time, providing medical staff with comprehensive and accurate information on the patient's digestive status. The controller judges the intragastric pressure data, the pH value of gastric fluid and the intragastric temperature data. When any of the data exceeds the preset threshold, the controller can automatically send a warning message to the medical staff. This real-time warning function enables medical staff to detect and deal with abnormal conditions of patients in a timely manner, thereby effectively reducing the risks caused by worsening of the disease or complications.

[0016] Furthermore, it also includes an alarm component, which includes an indicator light and a buzzer. The indicator light is used to flash and emit light of different colors to indicate different early warning reminders, and the buzzer is used to emit different alarm sounds. The indicator light and the buzzer are both connected to the controller signal. When the controller determines that any one of the intragastric pressure data, the pH value of the gastric fluid or the temperature exceeds a preset threshold, the alarm component can emit an audible and visual alarm signal to remind medical staff to take timely measures.

[0017] Beneficial effects: By integrating alarm components, including indicator lights and buzzers, this solution can immediately send out an audible and visual alarm signal when the controller determines that any of the intragastric pressure data, pH value of gastric fluid or temperature exceeds the preset threshold. This dual warning method is not only more intuitive, but also can quickly attract the attention of medical staff, ensuring that they can respond in time and take effective measures, thereby reducing the risk of worsening of the disease or complications.

[0018] Furthermore, an adaptive component is installed on one side of the nose bracket, and the adaptive component includes a plurality of springs. A mounting groove is provided on one side of the nose bracket, one end of each spring is fixedly connected to the mounting groove, and the other end of each spring is fixedly connected to a pad, and a plurality of air holes are opened on the pad; The pads are all fixedly connected with anti-skid pads, which are used to prevent the nose bracket from shifting or falling off due to the patient's activities. The anti-skid pads are made of medical-grade silicone material, and the ventilation holes all run through the anti-skid pads.

[0019] Beneficial effects: The introduction of adaptive components, especially the design of springs and pads, enables the nose bracket to be adaptively adjusted according to the patient's nose shape. The elastic effect of the spring enables the pad to fit closely to the patient's nose bridge and nose wing area, thereby improving the wearing comfort and stability and reducing the patient's discomfort caused by the displacement or falling off of the nose bracket.

[0020] The use of anti-skid pads further enhances the anti-skid effect of the nose bracket. The anti-skid pads made of medical-grade silicone material not only have good skin-friendliness and breathability, but also can effectively prevent the nose bracket from shifting or falling off due to patient activities (such as turning over, sitting up, etc.). The design of the air holes allows air to circulate on the pad, thereby improving the breathability when wearing the nose bracket and reducing the risk of skin inflammation and infection.

[0021] Furthermore, the triggering member includes a second pressure sensor and a tension sensor, the second pressure sensor is used to monitor in real time the pressure exerted by the fixing plate on the catheter, and the tension sensor is used to monitor in real time the tension exerted by the patient's own activities on the catheter.

[0022] Beneficial effects: By integrating the second pressure sensor and the tension sensor, the trigger can monitor in real time the pressure exerted by the fixing plate on the catheter and the tension exerted on the catheter by the patient's own activities. This real-time monitoring function enables the controller to accurately grasp the state of the catheter, thereby realizing intelligent control of the fixing plate. When the pressure or tension exceeds the preset threshold, the controller can respond quickly and issue instructions to ensure the stability of the catheter and the comfort of the patient. The real-time monitoring function of the trigger enables medical staff to adjust the fixing state of the catheter according to the actual situation of the patient. When the catheter is detected to be too tight or too loose, the controller can automatically adjust the position and state of the fixing plate, thereby realizing intelligent fixation and relaxation of the catheter. This intelligent adjustment method not only improves the patient's comfort, but also reduces problems such as skin damage and pain caused by improper catheter fixation.

[0023] Furthermore, the binding piece includes a binding belt, one end of which is fixedly connected to the nose bracket, and the other end of which is provided with a buckle for adjusting the length of the binding belt.

[0024] Beneficial effects: The introduction of the binding parts, especially the design of the binding belt and buckle, significantly enhances the fixation stability of the nose bracket and the entire gastric tube system. By adjusting the buckle, medical staff can flexibly adjust the length of the binding belt according to the size and shape of the patient's head, ensuring that the nose bracket fits tightly to the patient's nose bridge area and prevents displacement or falling off due to patient activities. This design not only improves the patient's wearing comfort, but also ensures the accuracy and continuity of the monitoring data.

[0025] Furthermore, it also includes a cleaning component, which includes a cleaning ring installed at both ends of the outer shell. The cleaning ring includes a shell, and a cleaning port is opened on the inner side of the shell. Cleaning cotton is detachably connected to the inside of the shell. The cleaning cotton in the cleaning ring on one side is in a dry state, and the cleaning cotton in the cleaning ring on the other side is filled with disinfectant.

[0026] Beneficial effects: The design of the cleaning component allows the catheter to be disinfected and cleaned at the same time during its passage. The cleaning cotton in the cleaning ring on one side is filled with disinfectant (such as alcohol), which can perform preliminary disinfection on the catheter and effectively kill bacteria and viruses on the surface of the catheter. The dry cleaning cotton in the cleaning ring on the other side can further remove residual dirt and moisture on the surface of the catheter to ensure the cleanliness and dryness of the catheter. This design not only improves the disinfection efficiency, but also enhances the disinfection effect and reduces the risk of infection caused by catheter contamination. By combining the design of dry cleaning cotton and cleaning cotton filled with disinfectant, the cleaning component can ensure the disinfection effect while avoiding excessive disinfectant residue, thereby reducing irritation and discomfort to the patient.

[0027] Furthermore, the power supply component includes a battery and a battery management module. The battery management module is used to monitor the battery power. The battery management module is connected to the controller signal. When the battery management module detects that the battery power is insufficient, the controller reminds medical staff to replace the battery.

[0028] Beneficial effects: The design of the signal connection between the battery management module and the controller enables the controller to receive a reminder signal in time and take corresponding measures when the battery is low. This design not only avoids problems such as sudden shutdown of the device or data loss due to battery exhaustion, but also improves the reliability and stability of the device. Medical staff can replace the battery in time according to the reminder of the battery management module to ensure the normal operation of the device and the safety of the patient.

[0029] Furthermore, it also includes a remote monitoring module, which is used to transmit the intragastric pressure, pH value, temperature and battery power information of the power supply component collected in real time by the monitoring component to the smart terminal through wireless communication technology.

[0030] Beneficial effects: Enhanced patient safety: Through the remote monitoring module, medical staff can monitor the patient's physiological parameters in real time. Once abnormalities are found, such as excessive intragastric pressure, pH imbalance or abnormal temperature, they can take immediate measures to intervene, thereby effectively preventing complications and enhancing patient safety. This design allows medical staff to monitor the patient's physiological parameters and equipment status anytime and anywhere, detect and handle abnormal situations in a timely manner, and improve the response speed and efficiency of medical services.

[0031] Furthermore, the outer surface of the catheter is provided with scale marks, which are used to help medical personnel determine the depth of insertion of the catheter into the stomach.

[0032] Beneficial effects: The scale markings on the outer surface of the catheter provide an intuitive reference for medical staff to help them accurately judge the depth of the catheter inserted into the stomach. This design reduces the risk of complications caused by improper insertion depth, such as gastric perforation and esophageal injury, and improves the safety and effectiveness of treatment.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The following is further described in detail through specific implementation methods: Embodiment 1:

[0040] As attached Figures 1 to 5 As shown: A multifunctional gastric tube capable of real-time monitoring of intragastric pressure and pH value comprises a catheter 1, the outer surface of which is provided with scale marks, which are used to help medical personnel determine the depth of insertion of the catheter 1 into the stomach, thereby ensuring the safety and accuracy of the operation. It also comprises a monitoring component 2 for monitoring intragastric pressure and pH value, a power component and a fixed component and a controller for providing power to the monitoring component 2 (the controller is connected with a smart device signal, and the smart device includes but is not limited to a smart phone, a tablet computer, a laptop computer or a dedicated medical monitoring terminal), the monitoring component 2 is electrically connected with the power component, and the monitoring component 2 and the power component are both installed at one end of the catheter 1, the power component comprises a battery and a battery management module, the battery provides stable power support for the monitoring component 2, the battery management module is used to monitor the battery power, the battery management module is connected with the controller signal, and when the battery management module monitors that the battery power is insufficient, the controller reminds the medical personnel to replace the battery, thereby ensuring the continuity of the monitoring work.

[0041] The monitoring component 2 includes a first pressure sensor, a pH sensor and a temperature sensor. The first pressure sensor is used to monitor the pressure change in the stomach in real time by using a piezoresistive or capacitive principle (i.e., when the pressure in the stomach changes, the sensitive element of the first pressure sensor will deform, thereby changing the resistance or capacitance value, and then generating an electrical signal proportional to the pressure), and convert the pressure signal into an electrical signal and output it to the controller to help medical staff understand the pressure condition of the patient's stomach. The pH sensor is used to measure the pH value of the gastric juice by measuring the hydrogen ion concentration in the gastric juice based on the electrochemical principle (i.e., the pH sensor usually contains a glass electrode and a reference electrode. When the two are immersed in the gastric juice, a primary battery is formed. The pH value of the gastric juice can be obtained by measuring its electromotive force), and the measured pH value is converted into an electrical signal and transmitted to the controller, which is of great significance for determining whether the patient has problems such as too much or too little gastric acid. The temperature sensor is used to monitor the temperature data in the stomach by using principles such as thermistors or thermocouples, and convert the temperature data into an electrical signal and output it to the controller, providing medical staff with comprehensive information about the gastric environment. The controller judges the intragastric pressure data, the pH value of the gastric fluid and the temperature data in the stomach. When the controller judges that any one of the intragastric pressure data, the pH value of the gastric fluid or the temperature exceeds a threshold value, a warning message is issued to the medical staff.

[0042] The fixing assembly is detachably connected to the catheter 1, and the fixing assembly includes a nose bracket 3, which fits the patient's nose to provide a comfortable wearing experience for the patient. The nose bracket 3 is equipped with a binding piece for fixing the nose bracket 3 on the patient's head and a locking piece 4 for fixing the catheter 1. The binding piece includes a binding belt 10, one end of which is fixedly connected to the nose bracket 3, and the other end of the binding belt 10 is equipped with a buckle for adjusting the length of the binding belt 10, so as to ensure that the nose bracket 3 can be firmly fixed on the patient's head.

[0043] The locking member 4 includes an outer shell 401 and an inner shell 402, and an installation chamber 403 is provided between the outer shell 401 and the inner shell 402. A driving member is fixedly connected in the installation chamber 403. In this embodiment, the driving member is a micro motor 5. The output shaft of the driving member is fixedly connected to a driving gear 6. The driving gear 6 is meshed with a ring gear 7. The ring gear 7 is rotatably matched with the inner side wall of the inner shell 402. The ring gear 7 is meshed with a plurality of driven gears 8. The driven gears 8 are rotatably connected to the inner side wall of the outer shell 401. A spiral groove 701 is provided on the side of the ring gear 7 away from the driving gear 6. A plurality of fixed plates 9 are slidably matched in the spiral groove 701. The fixed plates 9 are distributed along the circumference of the ring gear 7.

[0044] A trigger is installed on one side of the fixing plate 9, and the trigger includes a second pressure sensor and a tension sensor. The second pressure sensor is used to monitor the pressure generated by the fixing plate 9 on the catheter 1 in real time, and the tension sensor is used to monitor the tension generated by the patient's own activities on the catheter 1 in real time. The second pressure sensor and the tension sensor are connected to the controller signal; when the real-time tension data monitored by the trigger exceeds the tension threshold, the controller sends a fixing instruction to the drive, and the operation of the drive causes the fixing plate 9 to tighten the fixation of the catheter 1 to prevent the catheter 1 from falling off or shifting due to the patient's activities. When the real-time pressure data monitored by the trigger exceeds the pressure threshold, the controller sends a loosening instruction to the drive, and the operation of the drive causes the fixing plate 9 to loosen the fixation of the catheter 1 to avoid excessive compression of the catheter 1.

[0045] The specific implementation process is as follows: Before intubation, medical staff need to conduct a comprehensive assessment of the patient to ensure that the use of the multifunctional gastric tube is safe and appropriate. Under the guidance of the medical staff, the patient fits the nose bracket 3 to the nose, and fixes the nose bracket 3 to the head through the binding belt 10 and the buckle to ensure that the nose bracket 3 is comfortable to wear and does not cause pressure or discomfort to the patient. And the monitoring component 2 is debugged through the controller to ensure that the first pressure sensor, pH sensor and temperature sensor can collect data normally and transmit the data to the controller in real time. Medical staff set the thresholds of intragastric pressure, gastric fluid pH and temperature according to the specific situation of the patient.

[0046] During intubation, medical staff must strictly follow the principle of aseptic operation to ensure the hygiene and safety of the intubation process. Medical staff pass the catheter 1 through the inner shell 402 of the fixed component on the nose bracket 3, and then insert the catheter 1 into the patient's stomach to an appropriate depth according to the scale mark. During this process, the patient's reaction must be closely monitored. If there is any discomfort or abnormality, the intubation should be stopped immediately and appropriate treatment measures should be taken.

[0047] After the intubation is completed, the medical staff starts the micro motor 5 through the controller, and the output shaft of the micro motor 5 drives the driving gear 6, the driving gear 6 drives the gear ring 7 meshing therewith, and the gear ring 7 drives the driven gear 8 meshing therewith, which not only realizes the transmission of power, but also ensures the balance and stability of the entire transmission system. The rotation of the gear ring 7 causes the fixed plate 9 to move in the spiral groove 701, so that the rotation of the gear ring 7 can be smoothly and efficiently converted into the linear movement of the fixed plate 9. As the fixed plate 9 moves, a moderate squeeze is gradually generated on the outer wall of the catheter 1, thereby achieving a stable fixation of the catheter 1. This fixing method not only ensures the stable position of the catheter 1 in the patient's body, but also greatly reduces the risk of displacement or falling off of the catheter 1 due to patient activities.

[0048] During the insertion process, the second pressure sensor of the trigger assembly monitors the squeezing force of the fixing plate 9 on the catheter 1 in real time. When the real-time monitoring data of the second pressure sensor does not match (exceeds or falls below) the threshold value in the controller, it indicates that the fixing portion of the catheter 1 by the fixing plate 9 is stable (over-squeezed or loosened), and the controller adjusts the power of the micro motor 5, thereby adjusting the force of the fixing plate 9. This ensures that the catheter 1 will neither be damaged due to excessive squeezing nor lose stability due to loosening.

[0049] While the patient is wearing the multifunctional gastric tube, the monitoring component 2 will continuously collect data such as intragastric pressure, gastric fluid pH and temperature, and transmit the data to the controller in real time. The controller processes and analyzes the received data to determine whether the data exceeds the preset threshold. When the data exceeds the threshold, the controller will issue a warning message, such as a sound alarm or flashing lights, to alert medical staff. Based on the warning information, medical staff will check the patient's monitoring data in a timely manner, and take appropriate treatment measures based on the patient's specific situation, such as adjusting the insertion depth of the gastric tube or changing the medication.

[0050] During the patient's activities, when the real-time tension data detected by the tension sensor exceeds the preset tension threshold, it means that the patient's activities may be more intense and the catheter 1 is at risk of falling off or shifting. At this time, the controller will respond quickly and issue a fixing instruction. By finely adjusting the power of the micro motor 5, the position of the fixing plate 9 in the spiral groove 701 can be adjusted, so that the catheter 1 can be fixed more tightly. This dynamic adjustment mechanism ensures the stability of the catheter 1 during the patient's activities and effectively reduces the medical risks caused by the falling off or shifting of the catheter 1.

[0051] On the contrary, when the real-time tension data monitored by the tension sensor is lower than the tension threshold, it indicates that the patient's activities are relatively stable and the catheter 1 is in a relatively safe state. At this time, the controller will issue a loosening command to adjust the power of the micro motor 5 so that the fixing plate 9 can moderately relax the fixation of the catheter 1. This design not only improves the patient's comfort and reduces the discomfort that may be caused by long-term excessive compression, but also ensures that the catheter 1 can quickly respond to changes in the patient's activities when necessary. By monitoring the displayed data on the controller, medical staff can intuitively understand the working status of the fixing components and the tension on the catheter 1. This visual management method enables medical staff to more accurately judge the suitability of the fixation of the catheter 1, so as to make timely adjustments to ensure that the catheter 1 is safely and comfortably fixed in the patient's body. The details are as follows: 1. Application of multifunctional gastric tube in patients with hyperacidity: Patient A suffered from stomach discomfort due to excessive gastric acid, so the doctor decided to use a multifunctional gastric tube for real-time monitoring. Before intubation, the medical staff set the threshold of gastric fluid pH to 2.0 according to the patient's specific situation (the normal gastric fluid pH range is 1.5-3.5, but it may be lower in patients with excessive gastric acid). After intubation, the monitoring component 2 began to collect data and transmit the data to the controller in real time.

[0052] While the patient is wearing the multifunctional gastric tube, the controller continuously receives and processes monitoring data. When the pH value of gastric fluid continues to be lower than the threshold, the controller sends a warning message to alert medical staff. Based on the warning message, medical staff promptly check the patient's monitoring data and, based on the patient's clinical symptoms, decide to give the patient antacid treatment. After treatment, the patient's gastric fluid pH value gradually returned to normal, and the symptoms of stomach discomfort were relieved.

[0053] 2. Application of multifunctional gastric tube in patients with abnormal intragastric pressure: Patient B suffered from bloating due to abnormal intragastric pressure, so the doctor decided to use a multifunctional gastric tube for real-time monitoring. Before intubation, the medical staff set the threshold of intragastric pressure to 20 mmHg (normal intragastric pressure range is 5-15 mmHg) according to the patient's specific situation. After intubation, the monitoring component 2 began to collect data and transmit the data to the controller in real time.

[0054] While the patient is wearing the multifunctional gastric tube, the controller continuously receives and processes monitoring data. When the intragastric pressure continues to be higher than the threshold, the controller sends a warning message to alert medical staff. Based on the warning message, the medical staff promptly checks the patient's monitoring data and, based on the patient's clinical symptoms, decides to give the patient gastrointestinal motility-promoting drugs. At the same time, the medical staff also helps the patient improve the abnormal intragastric pressure by adjusting the patient's diet and rest habits. After treatment, the patient's intragastric pressure gradually returned to normal and the symptoms of bloating were relieved.

[0055] 3. Application of multifunctional gastric tube in patients with abnormal gastric temperature: Patient C suffered from stomach discomfort due to abnormal stomach temperature, and the doctor decided to use a multifunctional stomach tube for real-time monitoring. Before intubation, the medical staff set the threshold of stomach temperature to 37.5℃ (normal stomach temperature range is 36.5-37.5℃) according to the patient's specific situation. After intubation, the monitoring component 2 began to collect data and transmit the data to the controller in real time.

[0056] While the patient is wearing the multifunctional gastric tube, the controller continuously receives and processes monitoring data. When the temperature in the stomach continues to be higher than the threshold, the controller sends a warning message to alert medical staff. Based on the warning message, medical staff promptly check the patient's monitoring data and, based on the patient's clinical symptoms, decide to give the patient appropriate treatment measures. After treatment, the patient's stomach temperature gradually returned to normal and the symptoms of stomach discomfort were relieved.

[0057] Embodiment 2:

[0058] The difference from Example 1 is that it also includes an alarm component, which includes an indicator light and a buzzer. The indicator light has the function of flashing in multiple colors, and each color represents a different warning level or reminder content. For example, red flashing may indicate that the intragastric pressure data is seriously beyond the safety range and emergency measures need to be taken immediately; yellow flashing may indicate that the pH value or temperature of the gastric fluid is close to the critical value, reminding medical staff to pay close attention and prepare to take corresponding measures. This color coding design enables medical staff to quickly judge the current warning situation based on the color of the indicator light. The buzzer can emit alarms of different frequencies and tones to further emphasize the urgency of the warning. For example, when the intragastric pressure data is abnormal, the buzzer may emit a continuous and urgent alarm; and when the pH value or temperature of the gastric fluid deviates from the normal range, it may emit an intermittent alarm. This sound coding design not only enhances the intuitiveness of the warning, but also enables medical staff to quickly perceive the warning signal through hearing even when the vision is obstructed. The indicator light and buzzer are both connected to the controller signal. When the controller determines that any of the intragastric pressure data, gastric fluid pH value or temperature exceeds the preset threshold, the alarm component can emit an audible and visual alarm signal to remind medical staff to take timely measures.

[0059] The specific implementation process is as follows: Medical staff first need to initialize the system, including setting preset thresholds for intragastric pressure, gastric pH, and temperature. After startup, each sensor begins to monitor the patient's intragastric environment data in real time and transmits the data to the controller in real time. The controller quickly analyzes the received data to determine whether each data exceeds the preset threshold.

[0060] When an abnormal situation is detected, the controller immediately triggers the alarm component, the indicator light flashes the corresponding color, and the buzzer sounds an alarm. Medical staff can quickly judge the warning situation based on the color of the indicator light and the alarm sound of the buzzer, and take corresponding treatment measures. At the same time, the controller will automatically record the time and type of each warning and the response of the medical staff for subsequent analysis and improvement.

[0061] Embodiment 3:

[0062] As attached Figure 6As shown, the difference from Example 2 is that an adaptive component is installed on one side of the nose bracket 3, and the adaptive component includes a plurality of springs 301, and the springs 301 are used to provide elasticity and adaptability. A mounting groove is provided on one side of the nose bracket 3, and one end of the spring 301 is fixedly connected to the mounting groove, and the other end of the spring 301 is fixedly connected to a pad 302, and a plurality of ventilation holes are opened on the pad 302, and the ventilation holes are used to improve the comfort when wearing and reduce the stuffiness that may be caused by long-term wearing.

[0063] The backing plate 302 is fixedly connected with an anti-skid pad, which is used to prevent the nose bracket 3 from shifting or falling off due to the patient's activities, thereby ensuring the stability of the nose bracket 3. The anti-skid pad is made of medical-grade silicone material, which has excellent anti-skid performance and skin compatibility. The air holes on the backing plate 302 all pass through the anti-skid pad, ensuring that the function of the air holes can be exerted, further improving the wearing comfort.

[0064] The specific implementation process is as follows: the nose bracket 3 is fitted on the patient's nose, and the anti-skid pad on the pad 302 is in direct contact with the patient's nose. Due to the elastic effect of the spring 301, the pad 302 and the anti-skid pad can better fit the shape of the patient's nose, improving the stability and comfort of wearing. The breathable design of the air hole helps to reduce the stuffiness when worn for a long time and improve the patient's wearing experience.

[0065] According to the actual wearing condition of the patient, the adaptive component can ensure the best fit and comfort of the nose bracket 3 by adjusting the elastic force of the spring 301 and the position of the pad 302. Regularly check the wear of the anti-skid pad and replace it with a new one if necessary to ensure the anti-skid performance and skin compatibility.

[0066] Through the above implementation process, the adaptive components of the nose bracket 3 can effectively improve the wearing stability and comfort, reduce the displacement or falling off problems caused by the patient's activities, and improve the patient's wearing experience.

[0067] Embodiment 4:

[0068] The difference from the third embodiment is that it also includes a cleaning assembly, which includes a cleaning ring, which is installed at both ends of the housing 401 (such as Figure 4 As shown, the cleaning ring includes a shell 11, a cleaning port is provided inside the shell 11, a cleaning cotton 12 is detachably connected inside the shell 11, and one side ( Figure 1 The cleaning cotton 12 in the cleaning ring is in a dry state, and the other side ( Figure 1 The cleaning cotton 12 in the cleaning ring (on the side away from the nose bracket 3) is filled with disinfectant, and the disinfectant in this embodiment is alcohol.

[0069] The specific implementation process is as follows: before use, the cleaning rings are installed at both ends of the housing 401, ensuring that the cleaning openings are aligned with the path of the catheter 1. Dry cleaning cotton 12 and cleaning cotton 12 soaked in disinfectant are installed inside the housing 11, ensuring that they can be firmly fixed in the housing 11 and will not hinder the passage of the catheter 1.

[0070] When in use, the catheter 1 is first inserted from the side of the cleaning ring filled with alcohol. The cleaning cotton 12 on this side will use the disinfection effect of alcohol to perform preliminary disinfection on the catheter 1. The catheter 1 continues to pass through the channel inside the shell 401 and then passes out from the other side (the side where the dry cleaning cotton 12 is located). The cleaning cotton 12 on this side will further remove the residual dirt and moisture on the surface of the catheter 1, while preventing excessive residual disinfectant from affecting the patient's comfort.

[0071] Regularly check the cleanliness of the cleaning cotton 12 and the remaining amount of disinfectant (such as alcohol). When the cleaning cotton 12 becomes dirty or the disinfectant is exhausted, take out and replace with new cleaning cotton 12 and disinfectant in time. The replacement process of the cleaning cotton 12 and disinfectant should be simple and easy to ensure that medical staff can complete it quickly without affecting the patient's treatment process.

[0072] Embodiment 5:

[0073] The difference from Example 4 is that it also includes a remote monitoring module, which is used to transmit the intragastric pressure, pH value, temperature and battery power information of the power supply component collected in real time by the monitoring component 2 to a smart terminal (such as a doctor's workstation, mobile device, etc.) through wireless communication technology (such as Wi-Fi, Bluetooth and 4G / 5G, etc.).

[0074] The specific implementation process is as follows: Before the medical device is used for the first time, the remote monitoring module needs to be initialized and configured. The configuration includes setting wireless communication parameters, the receiving address of the smart terminal, and the data transmission protocol.

[0075] The monitoring component 2 collects physiological parameters such as pressure, pH value, temperature, etc. in the stomach in real time and converts these data into digital signals. The remote monitoring module receives these digital signals and performs preprocessing (such as data format conversion, data compression, etc.) to reduce the amount of data transmission and improve transmission efficiency.

[0076] The remote monitoring module selects the appropriate communication method to establish a connection with the smart terminal based on the configured wireless communication parameters. After the connection is established, the remote monitoring module transmits the pre-processed data to the smart terminal through the wireless channel. During the data transmission process, the remote monitoring module will perform data encryption and integrity verification to ensure the security and reliability of the data.

[0077] After receiving the data, the smart terminal will decrypt and verify it. The processed data will be stored in the database and displayed in real time on the screen of the smart terminal. Doctors can view the patient's real-time physiological parameters and battery power information through the smart terminal to make timely diagnosis and treatment.

[0078] The remote monitoring module also has an exception handling function. When the physiological parameters are monitored to be out of the normal range or the battery power is too low, the remote monitoring module will automatically trigger the alarm mechanism. The alarm information will be transmitted to the smart terminal in real time through wireless communication technology, reminding the doctor to take timely measures.

[0079] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
