Description

Technical Field

[0001] The present 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. Traditional gastric tubes primarily function to drain gastric contents or administer nutrient solutions, performed manually or through simple mechanical devices. However, these tubes are relatively limited in function and cannot meet the complex requirements of real-time monitoring of the gastric environment.

[0003] With the continuous advancement of medical technology and the increasing emphasis on health management, real-time monitoring of intragastric pressure and pH has become increasingly important. These two indicators are crucial indicators of gastric function. By monitoring these data in real time, doctors can more accurately assess patients' digestive function, diagnose related conditions (such as gastroesophageal reflux disease and gastric ulcers), and promptly adjust treatment plans, thereby improving treatment outcomes and patients' quality of life.

[0004] However, existing gastric tube products still have many shortcomings in terms of real-time monitoring capabilities, fixation methods, and intelligence. For example, while some gastric tubes can monitor intragastric pressure, they cannot simultaneously monitor pH, preventing doctors from obtaining comprehensive gastric function data. Traditional binding or adhesive fixation methods not only have limited fixation effects but are also prone to tube displacement or dislodgment due to patient movement, potentially causing discomfort and skin damage. Furthermore, existing gastric tubes are relatively backward in terms of intelligence, unable to intelligently adjust to the patient's actual situation, such as automatically adjusting monitoring frequency and alarm thresholds, limiting 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 to achieve intelligent fixation and relaxation of the catheter, thereby improving the patient's comfort and safety.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a multifunctional gastric tube capable of monitoring intragastric pressure and pH value in real time, comprising a catheter, a monitoring component for monitoring intragastric pressure and pH value, a power supply component and a fixing component for providing power to the monitoring component, the monitoring component being electrically connected to the power supply component, the monitoring component and the power supply component being both mounted at one end of the catheter, the fixing component being detachably connected to the catheter, the fixing component comprising a nose bracket, a binding component for fixing the nose bracket to the patient's head and a locking component for fixing the catheter being mounted on the nose bracket, the locking component comprising an outer shell and an inner shell, an installation chamber being provided between the outer shell and the inner shell, a driving component being fixedly connected in the installation chamber, an output shaft of the driving component being coaxially fixedly connected to a driving gear, the driving gear being meshed with a gear ring, the gear ring being rotatably matched with an inner side wall of the inner shell, the gear ring being meshed with a plurality of driven gears, the driven gears being rotatably connected to the inner side wall of the outer shell, a spiral groove being provided on a side of the gear ring away from the driving gear, a plurality of fixing plates being slidably matched in the spiral groove, and the fixing plates being distributed along the circumference of the gear ring;

[0008] A trigger is installed on one side of the fixing plate. The trigger is used to monitor the tension 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.

[0009] When the real-time tension data monitored by the trigger 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;

[0010] When the real-time pressure data monitored by the trigger component exceeds the pressure threshold, the controller sends a loosening instruction to the driving component, and the driving component operates to cause the fixing plate to loosen the fixation of the catheter.

[0011] The technical principle of this solution is as follows: The monitoring component, located at one end of the catheter, monitors gastric pressure and pH in real time. This data is crucial for assessing a patient's digestive function and diagnosing related diseases. The power supply provides stable power to the monitoring component, ensuring the continuity and accuracy of the monitoring data.

[0012] The nose bracket is the core part of the fixing assembly. It is fixed to the patient's head by a binding, providing stable support. The locking part includes an outer shell, an inner shell, a driving part, 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 on 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. Based on the preset tension threshold and pressure threshold, the controller sends instructions to the driving part to make the fixing plate fix or loosen the catheter.

[0013] The above scheme has the following beneficial effects:

[0014] 1. Compared to conventional gastric tubes, this solution provides more accurate and comprehensive data on a patient's digestive status by monitoring intragastric pressure and pH in real time. This helps doctors more accurately assess a patient's digestive function, promptly identifying and addressing potential digestive issues, thereby improving treatment outcomes and patients' quality of life.

[0015] 2. The fixation assembly in this solution is ingeniously designed, particularly the locking element. Through the coordinated action of the driver, active gear, ring gear, driven gear, and retaining plate, this design achieves intelligent catheter fixation and release. This design not only improves catheter stability and reduces the risk of catheter displacement or dislodgement due to patient movement, but also enables dynamic adjustment of the catheter's fixation status through real-time monitoring by the trigger and intelligent control by the controller, thereby ensuring patient comfort and safety.

[0016] 3. Compared with existing fixation methods, the fixation component in this solution is more flexible and intelligent. Traditional fixation methods often rely on simple binding or gluing, which not only has limited fixation effectiveness but can also cause discomfort to the patient. However, the fixation component in this solution can automatically adjust the position and state of the fixation plate based on the tension and pressure applied to the catheter, thereby achieving intelligent fixation and relaxation of the catheter, improving patient comfort and user experience.

[0017] 4. The multifunctional gastric tube in this solution is also easy to maintain and replace. The fixed component and the tube are detachably connected, allowing medical staff to easily replace damaged parts or clean and disinfect the entire gastric tube, thus ensuring the hygiene and durability of the device. This design also reduces maintenance costs and difficulty of use, allowing more patients to benefit from this advanced medical device.

[0018] 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 the 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 the gastric fluid and the intragastric temperature data. When the controller judges that any one of the intragastric pressure data, the pH value of the gastric fluid or the temperature exceeds the threshold, it issues a warning message to the medical staff.

[0019] Beneficial Effects: The monitoring component integrates a first pressure sensor, a pH sensor, and a temperature sensor, capable of real-time monitoring of intragastric pressure changes, gastric fluid pH, and gastric temperature data, providing medical staff with comprehensive and accurate information on the patient's digestive status. The controller determines the intragastric pressure data, gastric fluid pH, and gastric temperature data. When any of these data exceeds a preset threshold, the controller automatically issues a warning message to medical staff. This real-time warning function enables medical staff to promptly detect and address abnormal patient conditions, effectively reducing the risks associated with worsening conditions or complications.

[0020] 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, 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.

[0021] Beneficial Effects: By integrating alarm components, including an indicator light and a buzzer, this solution can immediately issue an audible and visual alarm signal when the controller determines that any of the intragastric pressure data, gastric fluid pH, or temperature exceeds a preset threshold. This dual alarm method is not only more intuitive but also quickly attracts the attention of medical staff, ensuring that they can respond promptly and take effective measures, thereby reducing the risk of disease progression or complications.

[0022] Furthermore, an adaptive component is installed on one side of the nose bracket, and the adaptive component includes a plurality of springs. A mounting slot is provided on one side of the nose bracket, one end of each spring is fixedly connected to the mounting slot, and the other end of each spring is fixedly connected to a pad, and a plurality of ventilation holes are opened on the pad;

[0023] The pads are fixedly connected with anti-slip pads, which are used to prevent the nose bracket from shifting or falling off due to patient activities. The anti-slip pads are made of medical-grade silicone material, and the ventilation holes run through the anti-slip pads.

[0024] Beneficial Effects: The introduction of adaptive components, particularly the spring and backing plate design, allows the nose support to be adjusted to the patient's nose shape. The spring's elasticity allows the backing plate to fit tightly to the patient's nose bridge and nose wings, improving wearing comfort and stability while reducing discomfort caused by nose support shifting or falling off.

[0025] The use of anti-slip pads further enhances the nose support's anti-slip properties. Made from medical-grade silicone, the pads are not only skin-friendly and breathable, but also effectively prevent the nose support from shifting or falling out due to patient activity (such as turning over or sitting up). The ventilation holes allow air to circulate throughout the pads, improving breathability while wearing the nose support and reducing the risk of skin inflammation and infection.

[0026] 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 on the catheter by the patient's own activities.

[0027] Beneficial effects: By integrating a second pressure sensor and a 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 status 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 status of the catheter according to the actual situation of the patient. When it is detected that the catheter is too tight or too loose, the controller can automatically adjust the position and status 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 fixation of the catheter.

[0028] 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.

[0029] Beneficial Effects: The introduction of the binding, particularly the strap and buckle design, significantly enhances the stability of the nasal support and the entire gastric tube system. By adjusting the buckle, medical staff can flexibly adjust the length of the binding according to the patient's head size and shape, ensuring that the nasal support fits tightly to the patient's nasal bridge and prevents movement or dislocation due to patient movement. This design not only improves patient comfort but also ensures the accuracy and continuity of monitoring data.

[0030] Furthermore, it also includes a cleaning component, which includes a cleaning ring. The cleaning ring is installed at both ends of the outer shell. The cleaning ring includes a shell. 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.

[0031] Beneficial Effects: The cleaning assembly's design allows for simultaneous disinfection and cleaning of the catheter during its passage. The cleaning cotton in one cleaning ring, filled with disinfectant (such as alcohol), provides preliminary disinfection of the catheter, effectively killing bacteria and viruses on the catheter surface. The dry cleaning cotton in the other cleaning ring further removes residual dirt and moisture from the catheter surface, ensuring cleanliness and dryness. This design not only improves disinfection efficiency and effectiveness, but also reduces the risk of infection due to catheter contamination. By combining dry cleaning cotton with disinfectant-filled cleaning cotton, the cleaning assembly ensures effective disinfection while preventing excess disinfectant residue, thereby reducing irritation and discomfort to the patient.

[0032] 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 monitors that the battery power is insufficient, the controller reminds medical staff to replace the battery.

[0033] Beneficial Effects: The battery management module's signal connection to the controller ensures that when the battery is low, the controller receives a prompt warning and takes appropriate action. This design not only prevents sudden device shutdowns or data loss due to battery depletion, but also improves device reliability and stability. Medical staff can promptly replace the battery based on the battery management module's warnings, ensuring proper operation of the device and patient safety.

[0034] 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.

[0035] Beneficial Effects: Enhanced Patient Safety: Through the remote monitoring module, medical staff can monitor patients' physiological parameters in real time. If an abnormality is detected, such as excessive intragastric pressure, pH imbalance, or abnormal temperature, immediate intervention measures can be taken, effectively preventing complications and enhancing patient safety. This design allows medical staff to monitor patients' physiological parameters and device status anytime and anywhere, promptly identifying and addressing abnormalities, improving the responsiveness and efficiency of medical services.

[0036] Furthermore, the outer surface of the catheter is provided with scale marks, which are used to help medical personnel judge the depth of the catheter inserted into the stomach.

[0037] Beneficial Effects: The graduated markings on the outer surface of the catheter provide a visual reference for medical staff, helping them accurately determine the depth of the catheter insertion into the stomach. This design reduces the risk of complications caused by improper insertion depth, such as gastric perforation and esophageal injury, thereby improving the safety and effectiveness of treatment.

[0038] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0049] The following is further described in detail through specific implementation methods:

[0050] Example 1:

[0051] As attached Figures 1 to 5 A multifunctional gastric tube capable of real-time monitoring of intragastric pressure and pH is shown. The tube comprises a catheter 1, the outer surface of which is provided with graduated markings that help medical personnel determine the insertion depth of the catheter 1 into the stomach, ensuring safe and accurate operation. The tube also comprises a monitoring assembly 2 for monitoring intragastric pressure and pH, a power supply assembly for providing power to the monitoring assembly 2, a fixed assembly, and a controller (the controller is signal-connected to a smart device, including but not limited to a smartphone, tablet computer, laptop computer, or dedicated medical monitoring terminal). The monitoring assembly 2 is electrically connected to the power supply assembly, and both are mounted on one end of the catheter 1. The power supply assembly includes a battery and a battery management module, which provides stable power to the monitoring assembly 2. The battery management module is configured to monitor the battery charge and is signal-connected to the controller. When the battery management module detects low charge, the controller alerts medical personnel to replace the battery, ensuring continuous monitoring.

[0052] Monitoring assembly 2 includes a first pressure sensor, a pH sensor, and a temperature sensor. The first pressure sensor uses a piezoresistive or capacitive principle (i.e., when the intragastric pressure changes, the sensitive element of the first pressure sensor deforms, thereby changing the resistance or capacitance value, and thus generating an electrical signal proportional to the pressure) to monitor intragastric pressure changes in real time. The pressure signal is converted into an electrical signal and output to a controller, helping medical staff understand the patient's gastric pressure condition. The pH sensor measures the pH value of gastric fluid based on electrochemical principles by measuring the hydrogen ion concentration in gastric fluid (i.e., the pH sensor typically contains a glass electrode and a reference electrode. When immersed in gastric fluid, they form a galvanic cell, and the electromotive force is measured to determine the pH value of gastric fluid). The measured pH value is converted into an electrical signal and transmitted to the controller, which is important for determining whether the patient has excessive or insufficient gastric acid. The temperature sensor uses a thermistor or thermocouple principle to monitor gastric temperature data, converting the temperature data into an electrical signal and outputting 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 intragastric temperature data. When the controller judges that any one of the intragastric pressure data, the pH value of the gastric fluid or the temperature exceeds the threshold, a warning message is issued to the medical staff.

[0053] The fixing assembly is detachably connected to the catheter 1 and includes a nose bracket 3, which fits snugly against the patient's nose, providing a comfortable wearing experience. Mounted on the nose bracket 3 are a binding element for securing the nose bracket 3 to the patient's head and a locking element 4 for securing the catheter 1. The binding element includes a strap 10, one end of which is fixedly connected to the nose bracket 3 and the other end of which is equipped with a buckle for adjusting the length of the strap 10, ensuring that the nose bracket 3 is securely fixed to the patient's head.

[0054] The locking member 4 includes an outer shell 401 and an inner shell 402, with an installation chamber 403 between the outer shell 401 and the inner shell 402. A driving member is fixedly connected to 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 engaged with a ring gear 7. The ring gear 7 is rotated with the inner side wall of the inner shell 402. The ring gear 7 is engaged 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 engaged in the spiral groove 701. The fixed plates 9 are distributed along the circumference of the ring gear 7.

[0055] The fixed plate 9 is provided with a trigger member on one side, which includes a second pressure sensor and a tension sensor. The second pressure sensor is used to monitor the pressure generated by the fixed 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 signal connected with the controller; when the real-time tension data monitored by the trigger member exceeds the tension threshold value, the controller sends a fixing instruction to the driving member, and the driving member operates to tighten the fixed plate 9 on the catheter 1, preventing the catheter 1 from falling off or shifting due to the patient's activities. When the real-time pressure data monitored by the trigger member exceeds the pressure threshold value, the controller sends a loosening instruction to the driving member, and the driving member operates to loosen the fixed plate 9 on the catheter 1, avoiding excessive compression on the catheter 1.

[0056] 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 medical staff, the patient will paste the nose bracket 3 on the nose, and fix the nose bracket 3 on the head through the binding belt 10 and the buckle, to ensure that the nose bracket 3 is worn comfortably and will not cause compression or discomfort to the patient. And through the controller, the monitoring assembly 2 is debugged to ensure that the first pressure sensor, the pH sensor and the temperature sensor can normally collect data and transmit the data to the controller in real time. Medical staff set the threshold values of intragastric pressure, gastric juice pH value and temperature according to the specific situation of the patient.

[0057] During intubation, medical staff need to strictly follow the principle of aseptic operation to ensure the hygiene and safety of the intubation process. The medical staff will pass the catheter 1 through the inner shell 402 of the fixed assembly on the nose bracket 3, and then insert the catheter 1 into the patient's stomach to the appropriate depth according to the scale mark. In this process, the patient's reaction needs to be closely observed, and if there is any discomfort or abnormality, the intubation should be stopped immediately and appropriate measures should be taken.

[0058] After intubation is completed, the medical staff start the micro motor 5 through the controller, the output shaft of the micro motor 5 drives the driving gear 6, the driving gear 6 drives the gear ring 7 engaged with it, and the gear ring 7 drives the driven gear 8 engaged with it, not only realizing the transmission of power, but also ensuring the balance and stability of the entire transmission system. The rotation of the gear ring 7 makes the fixed plate 9 move in the spiral chute 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. With the movement of the fixed plate 9, a moderate extrusion is gradually generated on the outer side wall of the catheter 1, thereby realizing the 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 catheter 1 displacement or falling off due to patient's activities.

[0059] During the insertion process, the trigger assembly's second pressure sensor monitors the squeezing force exerted by the fixing plate 9 on the catheter 1 in real time. If the real-time monitoring data from the second pressure sensor differs from (exceeds or falls below) a threshold in the controller, it indicates that the fixing plate 9 is not firmly fixed on the catheter 1 (either over-squeezed or loose). The controller then adjusts the power of the micromotor 5, thereby adjusting the force exerted by the fixing plate 9. This ensures that the catheter 1 is neither damaged by over-squeezing nor unstable due to loosening.

[0060] While the patient is wearing the multifunctional gastric tube, the monitoring component 2 will continuously collect data such as intragastric pressure, gastric 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 an audible alarm or flashing lights, to alert medical staff. Based on the warning message, medical staff will promptly check the patient's monitoring data and take appropriate treatment measures based on the patient's specific situation, such as adjusting the insertion depth of the gastric tube or changing medications.

[0061] During patient movement, if the real-time tension data detected by the tension sensor exceeds the preset tension threshold, this indicates that the patient's movements may be intense, and there is a risk of catheter 1 falling off or shifting. At this point, the controller responds quickly and issues a fixation command. By finely adjusting the power of the micromotor 5, the position of the fixing plate 9 within the spiral groove 701 is adjusted, thereby more tightly securing the catheter 1. This dynamic adjustment mechanism ensures the stability of the catheter 1 during patient movement, effectively reducing the medical risks caused by the catheter 1 falling off or shifting.

[0062] 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 instruction to adjust the power of the micro motor 5 so that the fixing plate 9 can moderately loosen 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 display data on the controller, medical staff can intuitively understand the working status of the fixing component and the tension exerted 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:

[0063] 1. Application of multifunctional gastric tube in patients with excessive gastric acid:

[0064] Patient A experienced 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 gastric pH threshold to 2.0 based on the patient's specific condition. (The normal pH range is 1.5-3.5, but it may be lower in patients with excessive gastric acid.) After intubation, monitoring component 2 began collecting data and transmitting it to the controller in real time.

[0065] While the patient is wearing the multifunctional gastric tube, the controller continuously receives and processes monitoring data. When the gastric pH value consistently falls below the threshold, the controller issues an alert, alerting medical staff. Based on the alert, the medical staff promptly reviews the patient's monitoring data and, based on the patient's clinical symptoms, decides to administer antacid medication. Following treatment, the patient's gastric pH value gradually returned to normal, and his stomach discomfort symptoms were alleviated.

[0066] 2. Application of multifunctional gastric tube in patients with abnormal intragastric pressure:

[0067] Patient B suffered from abnormal intragastric pressure, leading to gastric bloating. The doctor decided to use a multifunctional gastric tube for real-time monitoring. Before intubation, the medical staff set the intragastric pressure threshold to 20 mmHg (normal intragastric pressure ranges from 5 to 15 mmHg) based on the patient's specific condition. After intubation, Monitoring Component 2 began collecting data and transmitting it to the controller in real time.

[0068] While the patient is wearing the multifunctional gastric tube, the controller continuously receives and processes monitoring data. When the intragastric pressure remains above the threshold, the controller issues a warning message to alert medical staff. Based on the warning message, medical staff promptly review the patient's monitoring data and, based on the patient's clinical symptoms, decide to administer prokinetic medication. At the same time, medical staff also help the patient improve abnormal intragastric pressure by adjusting their diet and daily habits. After treatment, the patient's intragastric pressure gradually returned to normal, and their bloating symptoms were alleviated.

[0069] 3. Application of multifunctional gastric tube in patients with abnormal gastric temperature:

[0070] Patient C experienced stomach discomfort due to abnormal stomach temperature, so the doctor decided to use a multifunctional gastric tube for real-time monitoring. Before intubation, the medical staff set the stomach temperature threshold at 37.5°C (normal stomach temperature range is 36.5-37.5°C) based on the patient's specific condition. After intubation, monitoring component 2 began collecting data and transmitting it to the controller in real time.

[0071] While the patient is wearing the multifunctional gastric tube, the controller continuously receives and processes monitoring data. If the stomach temperature remains above a threshold, the controller issues an alert, alerting medical staff. Based on the alert, medical staff promptly review the patient's monitoring data and, based on the patient's clinical symptoms, decide on appropriate treatment. Following treatment, the patient's stomach temperature gradually returned to normal, and stomach discomfort symptoms were alleviated.

[0073] This embodiment differs from Example 1 in that it also includes an alarm component, consisting of an indicator light and a buzzer. The indicator light can flash in multiple colors, each representing a different warning level or alert. For example, flashing red may indicate that the intragastric pressure data is seriously outside the safe range, requiring immediate emergency measures; flashing yellow may indicate that the gastric pH or temperature is approaching a critical value, prompting medical staff to pay close attention and prepare to take appropriate measures. This color-coded design allows medical staff to quickly determine the current warning situation based solely 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, rapid alarm; when the gastric pH or temperature deviates from the normal range, it may emit an intermittent alarm. This sound-coded design not only enhances the intuitiveness of the warning, but also allows medical staff to quickly perceive the warning signal through hearing, even when 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.

[0074] 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. Once activated, the sensors begin monitoring the patient's intragastric environment in real time and transmit this data to the controller. The controller quickly analyzes the received data to determine whether any of the parameters exceed the preset thresholds.

[0075] When an abnormality is detected, the controller immediately triggers the alarm component, causing the indicator light to flash the corresponding color and the buzzer to sound an alarm. Based on the indicator light color and the buzzer sound, medical staff can quickly determine the warning situation and take appropriate measures. The controller also automatically records the time and type of each warning and the medical staff's response for subsequent analysis and improvement.

[0076] Example 3:

[0077] 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. The adaptive component includes several springs 301, which are used to provide elasticity and adaptability. A mounting slot is provided on one side of the nose bracket 3. One end of each spring 301 is fixedly connected to the mounting slot. The other end of each spring 301 is fixedly connected to a backing plate 302. The backing plate 302 has several ventilation holes. The ventilation holes are used to improve wearing comfort and reduce the stuffiness that may be caused by long-term wear.

[0078] A non-slip pad is fixedly attached to each backing plate 302. This pad prevents the nose bracket 3 from shifting or falling due to patient movement, ensuring its stability. Made of medical-grade silicone, the pad offers excellent anti-slip properties and skin compatibility. The ventilation holes on the backing plate 302 extend through the pad, ensuring full functionality and further enhancing wearing comfort.

[0079] The specific implementation process is as follows: The nose bracket 3 is placed against the patient's nose, with the anti-slip pad on the backing plate 302 in direct contact with the patient's nose. Due to the elasticity of the spring 301, the backing plate 302 and the anti-slip pad are able to better conform to the shape of the patient's nose, improving wearing stability and comfort. The ventilation holes help reduce the feeling of stuffiness during prolonged wear, enhancing the patient's wearing experience.

[0080] According to the patient's actual wearing situation, 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-slip pad and replace it with a new one if necessary to ensure anti-slip performance and skin compatibility.

[0081] 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.

[0082] Example 4:

[0083] The difference from Example 3 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 opened inside the shell 11, and a cleaning cotton 12 is detachably connected to the inside of the shell 11. Figure 1 The cleaning cotton 12 in the cleaning ring is dry, 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, which is alcohol in this embodiment.

[0084] The specific implementation process is as follows: Before use, install the cleaning rings at both ends of the housing 401, ensuring that the cleaning openings are aligned with the path of the catheter 1. Install a dry cleaning cotton 12 and a disinfectant-soaked cleaning cotton 12 inside the housing 11, ensuring that they are firmly fixed in the housing 11 and do not hinder the passage of the catheter 1.

[0085] During use, catheter 1 is first inserted through the side of the cleaning ring filled with alcohol. Cleaning cotton 12 on this side utilizes the alcohol's disinfecting effect to initially disinfect catheter 1. Catheter 1 continues through the passage inside housing 401 and exits through the other side (where dry cleaning cotton 12 is located). Cleaning cotton 12 on this side further removes residual dirt and moisture from the surface of catheter 1, while also preventing excessive disinfectant residue from affecting patient comfort.

[0086] Regularly check the cleanliness of the cleaning pad 12 and the remaining amount of disinfectant (e.g., alcohol). When the cleaning pad 12 becomes dirty or the disinfectant is depleted, promptly remove and replace it with a new one. The replacement process for the cleaning pad 12 and disinfectant should be simple and easy for medical staff to complete quickly without disrupting the patient's treatment progress.

[0087] Example 5:

[0088] 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 an intelligent terminal (such as a doctor's workstation, mobile device, etc.) through wireless communication technology (such as Wi-Fi, Bluetooth and 4G / 5G, etc.).

[0089] 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.

[0090] Monitoring component 2 collects real-time intragastric physiological parameters such as pressure, pH, and temperature, and converts these data into digital signals. The remote monitoring module receives these digital signals and performs preprocessing (such as data format conversion and data compression) to reduce data transmission volume and improve transmission efficiency.

[0091] The remote monitoring module selects the appropriate communication method based on the configured wireless communication parameters to establish a connection with the smart terminal. Once the connection is established, the remote monitoring module transmits the pre-processed data to the smart terminal via a wireless channel. During data transmission, the remote monitoring module performs data encryption and integrity verification to ensure data security and reliability.

[0092] After receiving the data, the smart terminal decrypts and verifies it. The processed data is stored in a database and displayed in real time on the smart terminal screen. Doctors can use the smart terminal to view the patient's real-time physiological parameters and battery level information, enabling timely diagnosis and treatment.

[0093] The remote monitoring module also features exception handling. If physiological parameters are detected outside the normal range or the battery level is low, the module automatically triggers an alarm. This information is transmitted to the smart terminal in real time via wireless communication technology, alerting the doctor to take timely action.

[0094] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
