Description

Technical Field

[0001] This invention relates to the field of human rehabilitation technology, and in particular to an application system of seated Baduanjin (Eight Pieces of Brocade) in COPD mechanical ventilation patients. Background Technology

[0002] Chronic obstructive pulmonary disease (COPD) is a common chronic disease characterized by recurrent flare-ups, high mortality, and a severe burden on patients' mental and economic well-being, impacting their physical and mental health, daily living abilities, and quality of life. The prevalence of COPD is also increasing annually. In 2016, 3 million people worldwide died from COPD, accounting for 5.4% of global deaths, making it the third leading cause of death globally. Patients experience recurrent lung infections and recurrent flare-ups, requiring repeated hospitalizations. Often, by the time they arrive at the hospital, they have already developed respiratory failure, and in most cases, mechanical ventilation is the only treatment option to alleviate symptoms such as shortness of breath and wheezing; it is incurable. The Seated Eight-Section Brocade Therapy is a dynamic exercise within meditation, one of the internal energy cultivation methods. It can be used for the conditioning of those suffering from chronic and debilitating diseases. It is an ancient Chinese health preservation method, highly recommended by numerous medical and health experts during the Ming and Qing dynasties. It consists of eight movements, combining movement and stillness. During practice, breathing, guidance, and mental focus are coordinated; the movements are gentle, natural, smooth, simple, clear, and easy to learn and practice. Long-term exercise can effectively improve physical health and achieve the effects of disease prevention and strengthening the body.

[0003] Therefore, a sitting Baduanjin exercise system is proposed for use in COPD mechanically ventilated patients. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] To achieve the above objectives, the first aspect of this invention proposes an application system for seated Baduanjin exercises in COPD mechanically ventilated patients, including a nurse triage intervention module, a human-machine synchronization module, a multi-dimensional monitoring and early warning module, and a continuity management module.

[0006] The nurse triage intervention module includes an auxiliary group, a guidance group, and a data group. The auxiliary group performs compensatory movements for patients with muscle strength <3. The guidance group conducts pre-breathing exercise training and provides guidance on movements and breathing rhythm for patients with muscle strength >3. The data group simultaneously records the airway pressure fluctuation value and cooperation score of patients during exercise, forming a movement-physiological index correlation database.

[0007] The human-machine synchronization module includes a rhythm synchronization trainer. The rhythm synchronization trainer guides the patient to complete the pursed-lip abdominal breathing exercise through abdominal rise and fall animation. After the patient's respiratory rate is stabilized at 10-12 breaths / min and the tidal volume fluctuation is <10%, the exercise enters the action stage, with light and voice prompts to match the seated Baduanjin movements with the ventilator's delivery rhythm.

[0008] The multi-dimensional monitoring and early warning module collects the patient's physiological indicators, symptom feedback and movement data in real time. The physiological indicators include blood gas analysis indicators and ventilator airway pressure data. The symptom feedback is realized through the patient's preset gestures. The movement data is collected by the wristband sensor to collect the movement speed. When any indicator exceeds the preset threshold, an audible and visual alarm is triggered.

[0009] The continuity management module includes a home mechanical ventilation adaptation toolkit and a remote monitoring interface. The toolkit includes a simplified action flowchart and a home version of the action adjustment video. The remote monitoring interface can be connected to a home ventilator.

[0010] In addition, the application system of the sitting Baduanjin exercise in COPD mechanical ventilation patients proposed above according to the present invention may also have the following additional technical features:

[0011] Further description of the technical solution of the present invention:

[0012] The specific action compensation operation of the auxiliary nurses is as follows: the nurse fixes the patient's elbow joint with one hand and lifts the patient's wrist with the other hand, and assists in completing the action by raising the arm 30° while inhaling and lowering it while exhaling.

[0013] The nurse gently supports both sides of the patient's head, limiting the circular head movement angle to 20-30°.

[0014] Further description of the technical solution of the present invention:

[0015] The rhythm synchronization trainer is also equipped with a mode adaptation button. When the patient selects the synchronized intermittent mandatory ventilation mode, the trainer automatically sets the voice prompt interval to 7-8 seconds.

[0016] When the patient selects the assisted control mode, the trainer reads the ventilator's real-time inspiratory time via Bluetooth and adjusts the light duration to inspiratory time + 0.5 seconds.

[0017] Further description of the technical solution of the present invention:

[0018] The pre-breathing exercise training conducted by the nurses in the guidance group is divided into three stages. The first stage is static abdominal breathing. The patient lies flat, and the nurse places her hand on the patient's abdomen and instructs the patient to push the nurse's palm up when inhaling through the nose and to sink the abdomen when exhaling through pursed lips.

[0019] The second stage is dynamic abdominal breathing. The patient sits up and rubs their palms together, inhaling while rubbing their hands and exhaling while raising their hands.

[0020] The third stage is ventilation mode adaptation breathing. The nurse simulates the breathing rhythm of the ventilator and uses a metronome to make beeping sounds to guide the patient to breathe in rhythm.

[0021] Further description of the technical solution of the present invention:

[0022] The human-machine synchronization module is worn on the patient's wrist with a soft wrist brace. The wrist brace has a built-in pressure sensor. When the tapping force is greater than 5N, the sensor triggers a vibration reminder to avoid excessive force that could cause a sudden increase in the patient's heart rate.

[0023] A non-slip mat was placed under the patient's feet, and the nurse adjusted the head of the bed to a 30° angle in advance.

[0024] Further description of the technical solution of the present invention:

[0025] The symptom feedback method also includes dual backup of voice and buttons. For patients who cannot make clear gestures, they can speak keywords or press the corresponding button through the voice acquisition device installed at the bedside. After receiving the signal, the system will immediately synchronize it to the nurse station display screen and trigger a graded warning. The system can then remotely guide the adjustment of actions via walkie-talkie.

[0026] Further description of the technical solution of the present invention:

[0027] The home mechanical ventilation adapter kit also includes a simple muscle strength assessor, a positioning aid pad, and a motion timing hourglass;

[0028] The simple muscle strength assessment device reads grip strength values ​​and remotely adjusts the difficulty of the movement based on the grip strength values;

[0029] The positioning pad prevents the body from leaning forward, which would affect ventilation efficiency;

[0030] The action timing hourglass has a duration of 15 minutes and 30 minutes respectively.

[0031] Further description of the technical solution of the present invention:

[0032] The preset thresholds for the multi-dimensional monitoring and early warning module are: blood oxygen saturation < 92%, heart rate increase from baseline > 20 beats / min, and respiratory rate > 24 breaths / min.

[0033] Further description of the technical solution of the present invention:

[0034] The data set is compiled monthly, including patient mechanical ventilation time, weaning success rate, 6-minute walk distance, and St. George's Respiratory Questionnaire score. These indicators are then correlated with the action execution data.

[0035] Further description of the technical solution of the present invention:

[0036] The remote monitoring interface has an automatic feedback function for abnormal parameters. When the home ventilator detects that the patient is practicing the sitting Baduanjin exercise and the airway peak pressure is >30cmH2O or the positive end-expiratory pressure deviates from the preset value by >2cmH2O, the interface will automatically send the abnormal data and the corresponding action video to the nurse's APP.

[0037] Advantages of this invention:

[0038] It improves patients' ability to take care of themselves in daily life, improves the severity of their disease, reduces the length of hospital stay, promotes early rehabilitation of COPD patients on mechanical ventilation, enhances lung function by exercising after discharge, avoids recurrence of the disease, improves quality of life, reduces hospitalization rate, increases patient and family satisfaction, shortens the length of hospital stay for COPD patients, reduces hospitalization costs, lowers readmission rate, and also reduces the economic burden on society.

[0039] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0040] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein:

[0041] Figure 1 This is a system schematic diagram of the present invention;

[0042] Figure 2 This is a graph showing the experimental data of the present invention. Detailed Implementation

[0043] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0044] Embodiment 1 of the present invention will now be described with reference to the accompanying drawings:

[0045] like Figure 1-2 As shown, the application system of the seated Baduanjin exercise in COPD mechanically ventilated patients according to Embodiment 1 of the present invention includes a nurse triage intervention module, a human-machine synchronization module, a multi-dimensional monitoring and early warning module, and a continuity management module. Through the coordinated efforts of these modules, the system achieves the adaptation of seated Baduanjin exercises to mechanical ventilation and rehabilitation management for COPD mechanically ventilated patients.

[0046] The nurse triage intervention module is equipped with a nursing team that has qualifications as a respiratory specialist nurse or critical care specialist nurse. The nursing team is divided into an auxiliary group, a guidance group and a data group according to their responsibilities. The auxiliary group performs motor compensation operations for patients with muscle strength <3 grade. The guidance group conducts pre-breathing exercise training and provides guidance on movements and breathing rhythm for patients with muscle strength >3 grade. The data group simultaneously records the airway pressure fluctuation value and cooperation score of patients during exercise, forming a movement-physiological index correlation database.

[0047] In the above-mentioned nurse tiered intervention module, the specific action compensation operation of the auxiliary group nurses is as follows: For the "Holding Up the Sky with Both Hands to Regulate the Three Burners" movement in Baduanjin, the nurse fixes the patient's elbow joint with one hand and lifts the patient's wrist with the other hand, assisting in completing the movement by raising the arm 30° during inhalation and lowering it during exhalation, so as to avoid the patient's upper limb pulling the ventilator tubing due to insufficient muscle strength. For the "Shaking Head and Wagging Tail to Clear Heart Fire" movement in Baduanjin, the nurse gently supports the sides of the patient's head with her hands, limiting the circular swing angle of the head to 20-30°, to prevent the head shaking from causing friction damage to the airway mucosa caused by the endotracheal tube.

[0048] In the aforementioned nurse-level intervention module, the pre-training for breathing exercises conducted by the guidance group nurses is specifically divided into three stages. The first stage (1-3 minutes) is static abdominal breathing, where the patient lies flat and the nurse places their hand on the patient's abdomen, instructing the patient to push the nurse's palm up when inhaling through the nose and to sink the abdomen when exhaling through pursed lips. The second stage (3-5 minutes) is dynamic abdominal breathing, where the patient sits up and combines palm-to-palm rubbing motions, inhaling when rubbing hands and exhaling when raising hands. The third stage (2-3 minutes) is ventilation mode adaptation breathing, where the nurse simulates the ventilator's delivery rhythm, using a metronome to emit beeping sounds, instructing the patient to follow the rhythm and breathe synchronously, laying the foundation for subsequent synchronized actions.

[0049] In the aforementioned nurse tiered intervention module, the data team also needs to collect the following core rehabilitation indicators monthly: patient mechanical ventilation time, weaning success rate, 6-minute walking distance, and St. George's Respiratory Questionnaire score. These indicators will be correlated with the action execution data. If it is found that patients who perform the dorsiflexion and extension abdominal massage gastrointestinal adjustment action more than 5 times / week have a weaning success rate that is more than 20% higher than patients who perform the action less than 3 times / week, then this action will be included in the priority recommended training action and updated in the nursing operation manual.

[0050] The human-machine synchronization module includes a rhythm synchronization trainer. The rhythm synchronization trainer first guides the patient to complete the pursed-lip abdominal breathing exercise through abdominal movement animation. After the patient's respiratory rate stabilizes at 10-12 breaths / min and the tidal volume fluctuation is <10%, the movement stage is entered. The movement is matched with the rhythm of the ventilator by light and voice prompts. The duration of the light is consistent with the inspiratory time of the ventilator.

[0051] The aforementioned rhythm synchronization trainer is also equipped with a mode adaptation button, which corresponds to two core mechanical ventilation modes. When the patient selects the synchronized intermittent mandatory ventilation mode, the trainer automatically sets the voice prompt interval to 7-8 seconds (matching the regular respiratory cycle in this mode). When the patient selects the assisted control mode, the trainer reads the real-time inspiratory time (Ti) of the ventilator via Bluetooth and adjusts the light duration to Ti+0.5 seconds to ensure that the patient's movement begins slightly earlier than the ventilator delivers air, avoiding patient-ventilator asynchrony caused by delayed movement.

[0052] For the Neiguan and Quze movements in Baduanjin (tapping the elbow and wrist joints), a soft wrist brace is worn on the patient's wrist. The wrist brace has a built-in pressure sensor. When the tapping force is greater than 5N (exceeding the comfort threshold for COPD mechanical ventilation patients), the sensor triggers a vibration reminder to avoid excessive force that could cause a sudden increase in the patient's heart rate. For the foot dorsiflexion and extension movements in Baduanjin (pressing the abdomen to regulate the gastrointestinal tract), a non-slip mat is placed under the patient's feet. The nurse adjusts the head of the bed to a 30° angle in advance to ensure that the patient's body is stable when dorsiflexing and extending the feet, without affecting the position of the ventilator mask or intubation tube.

[0053] The multi-dimensional monitoring and early warning module collects patients' physiological indicators, symptom feedback and movement data in real time. Physiological indicators include blood gas analysis indicators and ventilator airway pressure data. Symptom feedback is achieved through the patient's preset gestures. Movement data is collected by the wristband sensor to collect movement speed. When any indicator exceeds the preset threshold, an audible and visual alarm is triggered.

[0054] The above-mentioned symptom feedback methods also include voice-button dual backup. For patients who cannot make clear gestures, they can speak keywords such as shortness of breath or discomfort through the voice acquisition device installed at the bedside, or press the corresponding button. After receiving the signal, the system will immediately synchronize to the nurse station display screen and trigger a graded warning. The red button triggers an immediate intervention warning, and the nurse must arrive at the bedside within 1 minute. The yellow button triggers an adjustment reminder warning, and the nurse can remotely guide the adjustment of actions through the intercom.

[0055] The aforementioned preset thresholds also include the patient's blood oxygen saturation (SpO2) <92%, heart rate increase from baseline >20 beats / min, and respiratory rate >24 breaths / min during exercise. When any of these indicators are detected to exceed the limit, the system will trigger an audible and visual alarm and automatically pop up an intervention suggestion window. For example, if SpO2 decreases, the pop-up window will prompt the patient to pause the exercise and adjust the ventilator oxygen concentration to 40%. If the heart rate increases, the pop-up window will prompt the patient to switch to abdominal massage to reduce the exercise load and provide nurses with immediate intervention references.

[0056] The continuity management module includes a home mechanical ventilation adaptation kit and a remote monitoring interface. The kit contains simplified action flowcharts and home version action adjustment videos. The remote monitoring interface can be connected to a home ventilator, enabling nurses to remotely track and guide patients' ventilator parameters and action execution during outpatient exercise.

[0057] The aforementioned home mechanical ventilation adapter kit also includes a simple muscle strength assessment device, which is a graduated grip ball. When the patient squeezes the grip ball, the grip strength value can be read (corresponding to muscle strength grades: grip strength <15kg indicates muscle strength ≤3, ≥15kg indicates muscle strength >3). The nurse can remotely adjust the difficulty of the movements based on the grip strength value. The positioning pad is a wedge-shaped soft pillow. When the patient practices the head-raising, chest-expanding, and blood-circulating exercises at home, the soft pillow is placed under the lower back to maintain a stable sitting posture and avoid the body leaning forward due to overly soft bedding, which would affect ventilation efficiency. The exercise timing hourglass has a duration of 15 minutes and 30 minutes (corresponding to the training time of seated Baduanjin), which helps the patient accurately control the exercise time at home and avoid overexertion.

[0058] The aforementioned remote monitoring interface also has an automatic feedback function for abnormal parameters. When the home ventilator detects that the patient is practicing the seated Baduanjin exercise and the peak airway pressure is >30cmH2O or the positive end-expiratory pressure (PEEP) deviates from the preset value by >2cmH2O, the interface will automatically send the abnormal data and the corresponding action video (collected through the home camera) to the nurse's APP. The nurse can then guide the patient or family to adjust the posture (such as avoiding excessive backward tilting when holding hands to the sky, which could lead to airway compression) via video link within 2 hours, or contact the community doctor to come to the home to adjust the ventilator parameters, forming a closed loop outside the hospital.

[0059] Example 2, illustrated below with a specific case:

[0060] The patient was a 68-year-old male with an acute exacerbation of COPD. He had been on mechanical ventilation via endotracheal intubation for 5 days, with SIMV ventilation mode. His spontaneous breathing rate was 60%, and his muscle strength was grade 3. Blood gas analysis showed PaCO2: 58 mmHg and PaO2: 82 mmHg. He had no neck and shoulder muscle atrophy or underlying cardiovascular disease. The treatment team consisted of 1 nurse in the support group, 1 nurse in the guidance group, and 1 nurse in the data group.

[0061] Specific implementation:

[0062] Preparation period:

[0063] Ventilator parameter pre-adaptation: The guidance team nurses adjusted the parameters according to the patient's SIMV mode and the actions to be performed. The trigger sensitivity was reduced from 2L / min to 1.2L / min, the respiratory cycle was set to 7 seconds (respiratory rate 8 breaths / min), and PEEP was maintained at 5cmH2O.

[0064] Rhythm guidance and monitoring deployment: A sound and light synchronizer is placed at the bedside, with a green light set to illuminate for 3 seconds (inhalation + initiation) and a red light set to illuminate for 4 seconds (exhalation + de-initiation). Voice prompts are provided for inhalation-initiation and exhalation-de-initiation. The patient wears an angular velocity wristband connected to a nurse's tablet. A synchronization warning line is added to the ventilator monitoring interface (an alarm is triggered when the airway pressure peak is greater than 15 cmH2O).

[0065] Execution period:

[0066] Pre-breathing exercise training: The nurses in the guidance group led the patients to complete 10 minutes of pursed-lip abdominal breathing. The wristband and ventilator monitoring showed that the respiratory rate was stable at 11 breaths / min and the tidal volume fluctuation was <8%, and the patients entered the action phase.

[0067] Quantitative guidance of movement rhythm: The patient follows the sound and light synchronization device to perform the movement. When the green light is on, the patient slowly raises both hands to the chest and slowly lowers them when the red light is on. When the patient opens the bow to the left and right, the patient extends one arm to within a 30cm radius of the chest when the green light is on and returns to the starting position when the red light is on. There is a 1-second pause at the transition point of the movement. The auxiliary nurses are on the side to protect the patient throughout the process to avoid pulling on the tubes.

[0068] Dynamic monitoring and intervention: In the 4th minute of the exercise, the ventilator monitoring showed that the airway pressure peak reached 16 cmH2O, triggering an alarm. The data group nurse recorded this moment as the transition period between left and right arm movements. The guidance group nurse immediately prompted the patient to slow down and adjusted the pause time between movements to 1.5 seconds. No alarms occurred afterward. The patient did not raise his left hand (the shortness of breath feedback gesture) throughout the exercise, and the movement speed remained stable at 18° / second.

[0069] Data Analysis:

[0070] Hospital data summary: The data team nurses recorded daily airway pressure fluctuations (from 16 cmH2O to 13 cmH2O) and cooperation scores (from 6 to 9 points). The summary showed that the correlation between the "lifting hands to the sky" exercise and the increase in PaO2 was 65%, so the frequency of training this exercise was increased.

[0071] Post-discharge care: Upon discharge, a home adaptation toolkit is provided, containing rhythm cards with action flowcharts and SIMV mode adaptation prompts. Patients scan a code to watch a bedding adaptation video and learn how to use a soft pillow under their lower back to maintain a stable sitting posture. Nurses view home ventilation data through a remote monitoring interface. On the 10th day, it was found that the patient's respiratory rate was 19 breaths / minute during practice. Remote guidance was provided to slow down the speed of the "lifting hands to the sky" posture, and the patient returned to normal after adjustment.

[0072] In summary, the patient's mechanical ventilation time was shortened to 8 days. Post-extubation blood gas analysis showed PaCO2 of 52 mmHg and PaO2 of 88 mmHg. A one-month follow-up after discharge showed muscle strength maintained at grade 3, and the patient could independently perform a simplified version of the sitting Baduanjin exercise. No ventilator-related complications occurred (e.g., ...). Figure 2 ).
