Description

Technical Field

[0001] This invention relates to the field of oral training technology, specifically to an oral training device for premature infants. Background Technology

[0002] Each year, premature infants account for about 10% of all newborns due to premature birth or low birth weight. Because their bodily functions are not fully developed, these premature infants often need to rely on breathing tubes and gastric tubes to maintain their lives. As a result, their oral muscles cannot coordinate the three rhythmic movements of sucking, swallowing and breathing independently. Therefore, if food or liquid is accidentally entered into the trachea or lungs, it will cause pneumonia.

[0003] In clinical practice, therapists typically use a method involving alternating increases and decreases in massage pressure with cot-covered fingers to stimulate premature infants. However, this method requires professional operation, has a long treatment period, and causes considerable inconvenience to families of premature infants. Furthermore, premature infants often require prolonged care, which undoubtedly increases the psychological stress and financial burden on their families.

[0004] Therefore, an oral training stick for newborns, infants, and toddlers has been launched on the market. It can cleverly replace the fingers inserted into the baby's mouth for oral training, making the oral training process simpler and easier, and greatly reducing the economic burden on families of premature babies.

[0005] However, while the aforementioned oral training sticks offer certain convenience and practicality, they still present some problems. The most prominent issue is that the vibration frequency can only be adjusted according to a preset program or manually controlled by a family member. This limitation makes it difficult to target specific muscles with varying intensity during training, thus affecting the therapeutic effect. Furthermore, training typically requires family members to move the handle outside the mouth to change the training position, which may lead to missed areas. Moreover, if the movement is not properly controlled, the training stick may deviate from its intended position, potentially even causing adverse reactions such as vomiting in premature infants. Summary of the Invention

[0006] The purpose of this invention is to provide an oral training device for premature infants. This technical solution can more effectively train the strength of various muscle groups in the oral cavity, thereby improving the coordination between sucking, swallowing and breathing.

[0007] To achieve the above objectives, this disclosure provides an oral training device for premature infants, including a heating module for collecting the oral temperature of the premature infant and heating a massage head according to the oral temperature of the premature infant; a massage module including a massage head and a vibration submodule, the vibration submodule being able to drive the massage head to produce a vibration effect; a rotation module for driving the massage head to rotate inside the premature infant's oral cavity; and a telescopic module for controlling the extension and retraction of the massage head.

[0008] The beneficial effects of the basic design: The massage head can simulate the shape of a finger and generate vibrations through the vibration submodule to massage the premature infant's mouth during oral training. The heating module heats the massage head, preventing overheating or cooling that could cause sensory stimulation to the premature infant, reducing the foreign body sensation, and ensuring smooth training. The rotation module simulates the multi-dimensional movement of a finger in the mouth, enabling massage of different tissues inside and outside the mouth, such as the lips, cheeks, tongue, palate, and gums, avoiding blind spots and making training more comprehensive. The massage head can rotate automatically without manual intervention from family members, allowing for more appropriate rotation amplitude and speed, and preventing excessive stimulation to the premature infant from movement. The telescopic module allows the massage head to move more flexibly in the mouth, making the massage process smoother, and can also be directly and promptly removed from the premature infant's mouth when necessary, ensuring the safety of training.

[0009] The aforementioned technical features make oral training devices for premature infants more effective, improve the professionalism of training, and reduce the difficulty of operation. Family members only need to keep the training device stable during training.

[0010] As a preferred feasible solution, the massage module also includes several pressure sensors distributed on the surface of the massage head, which can detect the contact pressure between the massage head and the oral muscles in real time.

[0011] As a feasible preferred solution, the heating module is provided with an overheat protection submodule, which is used to automatically cut off the power supply to the heating element when the temperature exceeds the set range.

[0012] As a feasible preferred solution, a communication module is also included for connecting to a control terminal via wired or wireless means, facilitating control of the device through the control terminal.

[0013] As a feasible preferred embodiment, it also includes a recording module, which includes a motion sensor for detecting the movement trajectory and angular changes of the rotating module within the oral cavity, and thereby analyzing the movement trajectory of the massage head within the oral cavity.

[0014] As a preferred feasible option, the recording module is also used to mark the location of massaged muscles in the preterm infant's mouth and display them visually.

[0015] As a feasible preferred embodiment, the device also includes a motion control module for controlling the movement of the massage head and for analyzing pressure data to determine the activity of the premature infant's oral cavity in order to adjust the movement trajectory of the massage head.

[0016] As a preferred feasible solution, the motion control module is also used to plan the training sequence based on the user's individual differences and training goals, including age, gender, and health status; and to generate the movement trajectory of the massage head according to the required training areas and training sequence.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings:

[0023] Explanation of reference numerals in the attached drawings: Electronic device 500, processor 501, communication interface 502, memory 503, bus 504.

[0024] Example 1

[0025] Reference Figure 1 An oral training device for premature infants, comprising:

[0026] The massage module includes a massage head and a vibration sub-module. The surface of the massage head is made of rubber to adapt to the shape and structure of the oral cavity. The vibration sub-module includes a small motor and an eccentric wheel. The motor drives the eccentric wheel to rotate, generating a vibration effect to simulate finger exercises for oral cavity training.

[0027] The massage module also includes several pressure sensors distributed on the surface of the massage head, which can detect the contact pressure between the massage head and the oral muscles in real time. By analyzing the pressure sensor data, it can be determined whether the target muscle has been successfully massaged, and the massage intensity and position can be adjusted as needed.

[0028] A heating module is used to heat the massage head to maintain the temperature of the premature infant's mouth. It includes a temperature sensor, employing a high-precision thermistor or infrared sensor, capable of accurately detecting the temperature inside the premature infant's mouth. Based on the data feedback from the temperature sensor, the heating module controls the power and heating time of the heating element to achieve a target temperature consistent with the premature infant's oral cavity, avoiding overheating or undercooling that could cause sensory stimulation. In this embodiment, the heating element can be a heating wire or a semiconductor heating chip.

[0029] The heating module is also equipped with an overheat protection submodule, which automatically cuts off the power supply to the heating element when the temperature exceeds the set range, so as to avoid overheating damage to the oral cavity of premature infants.

[0030] The rotating module is used to drive the massage head to rotate within the premature infant's mouth to a certain extent, and to control the rotation speed and amplitude of the rotating module to simulate the multidimensional movement of fingers in the mouth, so as to achieve massage and tapping of different tissues inside and outside the mouth, such as the lips, cheeks, tongue, palate, and gums.

[0031] The telescopic module, used to control the forward and backward movement of the massage head, includes a driver and a transmission mechanism. In this embodiment, the driver can be electric, pneumatic, or hydraulic, and can drive the massage head to telescopically move along an axis. This facilitates the massage head entering the oral cavity of a premature infant and allows it to move forward and backward within the mouth.

[0032] The communication module connects to the control terminal via wired or wireless means, facilitating device control through the terminal, which can be a remote control, mobile phone, or computer. Wireless communication can utilize technologies such as Bluetooth, Wi-Fi, or infrared, while wired communication can be achieved via a USB interface or other data transmission cables. The communication module receives commands and parameter settings from the control terminal and transmits them to the corresponding modules for execution. Simultaneously, the communication module can also feed back device status information, temperature data, and massage records to the control terminal, enabling two-way information exchange. Users can control the heating, massage, and rotation modules through the control terminal and view the device's operating status and data.

[0033] The recording module includes a motion sensor and a data storage device. The motion sensor, such as an accelerometer or gyroscope, detects the movement trajectory and angular changes of the rotating module within the infant's mouth and analyzes its movement. It also includes a display submodule to mark the locations of massaged muscles in the premature infant's mouth and display them visually, making it easier to see which muscles were missed during oral training and ensuring the quality of the training. This solution essentially collects personalized oral information from the premature infant, including the distances and relative positions between different training areas.

[0034] Example 2

[0035] The key difference between this embodiment and Embodiment 1 lies in the inclusion of a motion control module. This module controls the movement of the massage head. Oral training includes multiple areas requiring training. During rotation, a pressure sensor monitors real-time pressure changes in the premature infant's mouth. By analyzing this pressure data, the activity of the premature infant's mouth can be understood. For example, if the premature infant applies pressure while sucking or biting, the pressure sensor reading will change. Based on the pressure sensor reading, the motion control module can adjust the massage head's trajectory to coordinate with the premature infant's oral activities. For instance, if the premature infant applies pressure to the massage head with their tongue while sucking, the motion control module can adjust the massage head's trajectory to avoid the tongue and prevent conflict with oral activities.

[0036] In this way, the massage stick can rotate freely in the mouth, making it more flexible and smooth. At the same time, by avoiding interference with the premature infant's oral movements, the massage stick will not stimulate the premature infant. This helps ensure the safety and comfort of the massage process.

[0037] Example 3

[0038] The technical difference between this embodiment and Embodiment 2 is that the motion control module further includes a training planning submodule and a trajectory generation submodule.

[0039] The training planning submodule is used to plan the optimal training sequence based on the user's individual differences and training goals (such as improving bite strength). Individual differences include age, gender, health status, etc. The trajectory generation submodule is used to generate the movement trajectory of the massage head according to the required training areas and training sequence, so as to ensure that the massage head can reasonably complete the training of all areas.

[0040] It also includes a trajectory optimization submodule, which uses an improved ant colony algorithm to select the optimal movement trajectory of the massage head, specifically including the following steps:

[0041] An ant colony algorithm iterative model is constructed. In this embodiment, the model selection scheme corresponds to the change in the position of the massage head over continuous time. Based on the distance and relative position between the training parts of the premature infant, the model is built in three-dimensional coordinates, and the starting node and target node are set according to the data of the training planning submodule.

[0042] Initialize the ant colony algorithm parameters, including the number of ants, initial pheromone concentration, pheromone evaporation rate, and number of iterations. Place the ant colony at the source node and let the ants sequentially choose the next node until all ants reach the target node.

[0043] Construct the node selection function:

[0044]

[0045] In the formula, Let be the probability that the k-th ant will move from node i to node j at iteration number n. The pheromone concentration transferred from node i to node j. The visibility heuristic information variable represents the degree of heuristic for the ant's movement from node i to node j. In this embodiment, the visibility heuristic information variable is related not only to the distance between the two nodes, but also to the pressure applied to the massage head. and These are the pheromone factor and the pheromone concentration heuristic factor. This is a list of feasible nodes, where the nodes do not exist in the taboo list.

[0046] Constructing the energy-degree heuristic function:

[0047]

[0048] in, Let i be the set of neighboring nodes. Let the pressure be the sum of the pressures on all neighboring nodes of node i. By analyzing the pressure on the current node and the direction of that pressure, we can predict the pressures on its neighboring nodes. Let be the distance between nodes i and j. Let j be the current pressure experienced by node i's neighbor node.

[0049] Each ant in the ant colony starts from the node (0,0,0) and repeatedly executes the node selection function to select a node. It determines whether the ant has reached the target node. If it has not reached it, it continues to search for the next node until the ant reaches the target node. The nodes selected by the ant form a path.

[0050] Construct the pheromone update function:

[0051]

[0052] In the formula, The updated pheromone concentration. For pheromone evaporation rate, The pheromone concentration before the update. Let be the increase in pheromone concentration when the k-th ant moves from node i to node j at iteration number n. For a fixed increase in pheromone concentration, The operating power of the massage stick is transferred from node i to node j. For power The power loss factor under the following conditions The weighting is determined by the impact of power loss. The rotation radius affects the weight. Let be the radius of rotation from node i to node j; Let be the length of the trajectory from node i to node j. The weights are influenced by the trajectory length. By adding a factor to the pheromone concentration and assigning random values ​​within different ranges to different ants according to the rules in the formula, the pheromone concentration of different ants will show greater randomness differences, thereby changing the ants' enthusiasm for exploring new paths and avoiding local optima.

[0053] Therefore, after the ants in the ant colony have traversed all paths once, they update the pheromone concentration on each path according to the pheromone update function.

[0054] Determine if the iteration termination condition is met. If so, terminate the iteration and select the path with the highest pheromone concentration as the massage head movement trajectory. Otherwise, repeat the iteration steps and the judgment steps.
