BRIEF DESCRIPTION OF THE DRAWINGS
[0024] Various other advantages and benefits will become apparent to those skilled in the art upon reading the detailed description of the preferred embodiment below. The accompanying drawings are for illustration purposes only and are not to be considered as limiting the present invention. Throughout the drawings, the same reference figures denote the same components. In the drawings:
[0025] Figure 1 A structural diagram of a VR-based children's lung function rehabilitation training system in an embodiment of the present invention is shown. DETAILED DESCRIPTION
[0026] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0027] The embodiment of the present invention provides a VR-based children's lung function rehabilitation training system, such as Figure 1 As shown, including:
[0028] VR device 101 is worn on the head of the child patient to present an interesting virtual training scene. A respiratory sensor is provided in the VR device 101 to monitor the child patient's breathing and blowing conditions;
[0029] The body-worn device 102 is worn on the child patient's body and is used to collect the child patient's movement information;
[0030] The ECG monitoring sensor 103 is worn on the wrist of the child patient to monitor the heart rate of the child patient;
[0031] The data processing module 104 is connected to the VR device, the body-worn device 102 and the electrocardiogram monitoring sensor 103, and is used to evaluate the rehabilitation progress of the child patient based on the child patient's breathing condition, blowing condition, movement condition and heart rate condition.
[0032] In a specific embodiment, in order to improve the effect of pulmonary function rehabilitation training, various training scenarios are presented through the VR device 101. Specifically, the VR device 101 is used to:
[0033] Present a breathing exercise scene involving deep breathing and blowing up a balloon in a forest setting; or
[0034] Presenting adventure sports training scenarios within a marine environment; or
[0035] A game scene featuring a waterside environment.
[0036] Among them, by presenting a forest environment, child patients can be actively attracted to exhale and inhale, and at the same time, a scene of a balloon getting bigger and smaller according to the exhalation and inhalation situation can be presented, so that child patients can feel their own breathing conditions.
[0037] By presenting an ocean environment, various types of fish can be virtually created inside the ocean environment, thereby attracting child patients to catch fish and achieving exercise effects.
[0038] By presenting a waterside environment and simulating a paper boat floating on the water, children can be attracted to participate in a paper boat blowing competition, or by simulating multiple butterflies, children can be attracted to participate in a butterfly catching competition.
[0039] For different virtual scenarios, the breathing conditions, movement conditions, heart rate conditions and blowing conditions of child patients are collected. Moreover, in these scenarios, patients can be actively guided to make corresponding responses without the need for text prompts. Since some child patients are very young and cannot respond accurately to instructions, active guidance can better improve the cooperation of child patients.
[0040] The following provides active guidance methods for different scenarios.
[0041] The data processing module 104 is used to: create a training scenario of a virtual balloon that grows and shrinks based on the breathing condition of the child patient, and present the scenario through the VR device 101.
[0042] By making the balloon grow larger, the patient is guided to exhale. By making the balloon shrink, the patient is guided to inhale. Furthermore, the patient's exhalation and inhalation states can be recorded by a respiratory sensor within VR device 101. This approach can better enhance the motivation of children and improve the effectiveness of recovery training than voice guidance.
[0043] For example, by designing pursed lip breathing and abdominal breathing, and simulating the breathing movements of virtual characters, child patients are guided to imitate breathing while coordinating with the changes in the size of the balloon.
[0044] In another scenario, the data processing module 104 is used to: based on the movement of the child patient, present a scene of fish being caught and avoiding obstacles in a virtual ocean environment through a VR device.
[0045] Through the fishing game in the virtual ocean environment, other virtual characters catching fish are simulated around, so that the child patient can also imitate catching fish. At the same time, because they are in the sea, they need to hold their breath and inhale at the appropriate time. This requires not only exercise (catching fish), but also coordination with breathing. There are many creatures on the seabed, and some large creatures need to escape by dodging. The diversity of the virtually constructed ocean environment allows child patients to immerse themselves in an interesting ocean environment, which not only improves their training cooperation, but also improves the effect of rehabilitation training.
[0046] The intensity and force of the movement can be collected by the body-worn device 102. Specifically, the body-worn device 102 includes accelerometers corresponding to different parts of the body to collect the movement status of the child patient. For example, the accelerometer located at the arm detects acceleration, thereby determining that the arm is moving. Similarly, the movement of the leg can also be detected. At the same time, based on the magnitude of the acceleration, the intensity of the movement and other conditions can be determined, thereby determining the movement status.
[0047] There is also a virtual scene, the data processing module 104, which is used to: present a virtual scene of a paper boat floating on water based on the child patient's blowing situation, and present it through a VR device.
[0048] By presenting a game scene of blowing a paper boat on water and simulating other virtual characters blowing a paper boat, the child patient was encouraged to imitate the action. Simulating the boat's movement on the water with varying airflow heightened the fun. The competition format also enhanced the effectiveness of the practice. The specific duration and number of practice sessions were determined.
[0049] Through continuous practice by children, the purpose of rehabilitation training is achieved. As the number and duration of children's practice increase, their lung function can be clearly improved.
[0050] After collecting the child patient's breathing condition, blowing condition, movement condition and heart rate condition, the data processing module 104 evaluates the child patient's recovery progress based on the child patient's breathing condition, blowing condition, movement condition and heart rate condition.
[0051] The evaluation may be performed based on one collection condition or based on multiple collection conditions.
[0052] The following is an evaluation of each individual situation:
[0053] Regarding the assessment of cardiopulmonary function:
[0054] The data processing module 104 is used to determine the respiratory rate and respiratory depth based on the respiratory condition of the child patient, and evaluate the cardiopulmonary function of the child patient based on the respiratory rate and respiratory depth.
[0055] Different cardiopulmonary functions have corresponding respiratory rates and depths. Respiratory rates include resting and post-exercise recovery rates, while respiratory depth is determined by the contraction of the diaphragm and the expansion of the chest cavity. Deep breathing involves a large diaphragm depression, allowing the chest cavity to fully expand and absorb more oxygen. Shallow breathing relies on minimal chest movement, resulting in less gas exchange.
[0056] When both indicators are below the standard, it is determined that the child patient's cardiopulmonary function is poor. Of course, when both indicators are above the standard, it is determined that the child patient's cardiopulmonary function has returned to normal.
[0057] Regarding the assessment of respiratory muscle strength:
[0058] The data processing module 104 is used to evaluate the respiratory muscle strength of the child patient based on the child patient's blowing condition and the game results.
[0059] For example, the blowing condition is obtained in a paper boat blowing game constructed based on a virtual waterside environment. A virtual patient participates in the paper boat blowing game, and the respiratory muscle strength is obtained based on the results of the game, such as ranking or score.
[0060] The blowing conditions are collected by the breathing sensor in the VR device 101, and the paper boat in the virtual scene is matched to the floating of the paper boat according to the breathing conditions, thereby forming a contrast with the floating distance of other paper boats. The floating of other paper boats corresponds to different blowing levels.
[0061] Regarding the assessment of athletic ability:
[0062] The data processing module 104 is used to evaluate the exercise capacity of the child patient based on the child patient's exercise condition and heart rate condition.
[0063] Through a virtual fishing game in a virtual ocean environment, the child's movement patterns are captured, including the number of fish caught, the time it takes to catch them, and the difficulty of catching them. Heart rate data is also analyzed. Finally, based on the results and heart rate, the child's motor ability is assessed. The performance of other virtual characters in catching fish corresponds to different motor abilities. Therefore, by comparing the results with those of other virtual characters, the child's motor ability is determined.
[0064] The above is the assessment of a single situation. For the assessment of multiple situations, a comprehensive result can be obtained according to the weighted sum of the assessment results of a single situation to obtain the recovery status. I will not go into details here.
