Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an intelligent multi-mode positioning and warning system combining artificial intelligence with airway tools. Background Art

[0002] Airway management is an important skill in first aid and critical care medicine, aiming to ensure the patency of the patient's airway and maintain effective gas exchange. The medical behaviors covered include various aspects such as mask ventilation, laryngeal mask ventilation, non-invasive ventilation, tracheal intubation, etc.

[0003] Currently, airway management techniques and methods are relatively backward. In many cases, a blind exploration method is adopted, and it is necessary to rely on experience and indirect data to obtain judgments on the position and the situation that occurs.

[0004] Therefore, how to provide a safe airway management solution is exactly the technical problem to be solved by this application. Summary of the Invention

[0005] In view of the deficiencies of the existing technology, the present invention proposes an intelligent multi-mode positioning and warning system combining artificial intelligence with airway tools. This solution aims to formulate a comprehensive artificial intelligence and intelligent panoramic solution for airway management, helping anesthesiologists, critical care physicians, and respiratory physicians to achieve panoramic and intelligent monitoring and warning, and contributing to the future hospital construction.

[0006] Generally speaking, it is "artificial intelligence + three-dimensional reconstruction + visualization and positionable improved airway tools + intelligent multi-angle and scenario display technology + central airway data monitoring center", constructing a complete set of intelligent airway management solutions. Furthermore, it protects the safety of patients and reduces injuries, making it more precise, individualized, and intelligent. At the same time, doctors and patients are more comfortable.

[0007] The present invention provides an intelligent multi-mode positioning and warning system combining artificial intelligence with airway tools, and the technical solution is as follows:

[0008] The intelligent multi-mode positioning and warning system combining artificial intelligence with airway tools includes a main control unit, an airway tool, and a scanning unit, a modeling unit, and a display unit connected to the main control unit;

[0009] The scanning unit is used to scan the patient's airway to obtain the patient's three-dimensional airway data;

[0010] The modeling unit establishes a corresponding three-dimensional airway model according to the patient's three-dimensional airway data;

[0011] The main control unit is used to establish marking points at any position of the three-dimensional airway model, and the display unit is used to display the three-dimensional airway model and the marking points;

[0012] At the farthest end of the airway tool away from the handheld end, a positioning probe connected to the main control unit is provided. The main control unit determines the position of the airway tool through the positioning probe and displays the current position of the airway tool in the form of a dot on the three-dimensional airway model.

[0013] The main control unit preset an alarm distance threshold. When it is judged that the distance between the dot and the marking point is less than the alarm distance threshold, the main control unit generates a warning.

[0014] In summary, the present invention has the following beneficial effects: Through the method of three-dimensional airway reconstruction and positioning of the airway tool, doctors can intuitively see the position of the airway tool in the airway on the display unit, and the marking point can remind doctors of the distance between the airway tool and important positions, thereby protecting the safety of patients and reducing injuries, making it more precise, individualized and intelligent. At the same time, doctors and patients are more comfortable. Description of the Drawings

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Such as Figure 1As shown, an intelligent multi-mode positioning and warning system that combines artificial intelligence with an airway tool, which includes a main control unit 10, an airway tool 50, a scanning unit 20, a modeling unit 30, and a display unit 40 connected to the main control unit 10; the scanning unit 20 is used to scan the patient's airway to obtain three-dimensional airway data of the patient; the modeling unit 30 establishes a corresponding three-dimensional airway model based on the patient's three-dimensional airway data; the main control unit 10 is used to establish marking points at any position of the three-dimensional airway model, and the display unit 40 is used to display the three-dimensional airway model and the marking points; a positioning probe 51 connected to the main control unit 10 is provided at the farthest end of the airway tool 50 away from the handheld end, and the main control unit 10 judges the position of the airway tool 50 through the positioning probe 51 and displays the current position of the airway tool 50 on the three-dimensional airway model in the form of a dot; a warning distance threshold is preset by the main control unit 10, and when it is judged that the distance between the dot and the marking point is less than the warning distance threshold, the main control unit 10 generates a warning.

[0021] Through the method of three-dimensional airway reconstruction and positioning of the airway tool 50 in this application, doctors can intuitively see the position of the airway tool 50 in the airway on the display unit 40, and the marking points can remind doctors of the distance between the airway tool 50 and important positions, thereby protecting the safety of patients and reducing injuries, making it more precise, individualized, and intelligent. At the same time, doctors and patients are more comfortable.

[0022] Specifically, before the operation, the patient is scanned by the scanning unit 20 such as CT, and then the three-dimensional airway model is reconstructed by the modeling unit 30 to obtain the airway "Pangu model". After being converted by the conversion system in the main control unit 10, it is displayed on the display unit 40. At this time, the main control unit 10 can view the airway diameter of the patient and some of its characteristic data, and can also establish marking points at any position of the patient's three-dimensional airway model, generally at places such as the airbag and the target arrival position, to judge whether the airway tool 50 is approaching important points.

[0023] Furthermore, the main control unit 10 marks the abnormal lesion position through artificial intelligence, or can also actively mark the abnormal lesion through the main control unit 10.

[0024] There is a scale on the airway tool 50, with the positioning probe 51 as the origin.

[0025] Such as Figure 2 As shown, the system matches the dot and the three-dimensional airway model through the following process:

[0026] St10, the display unit 40 is connected to the laryngoscope. When it is judged through the laryngoscope that the airway tool 50 reaches the glottis, the main control unit 10 records that the dot reaches the glottis of the three-dimensional airway model.

[0027] St20. When it is judged through the endoscope that the airway tool 50 reaches the carina, control the endoscope to view the scale value of the airway tool 50 corresponding to the glottis opening, and record through the main control unit 10 that the dot reaches the carina of the three-dimensional airway model and record the corresponding scale value.

[0028] St30. The main control unit 10 matches the distance of the dot from the glottis opening to the carina in the three-dimensional airway model with the actual distance of the airway tool 50 from the glottis opening to the carina in the patient's body.

[0029] The actual position of the positioning probe 51 on the airway tool 50 needs to be matched and calibrated before the position of the dot can be accurately displayed on the three-dimensional airway model. Since the face and oral cavity will change during the operation, the glottis opening and the carina are used as anchor points, combined with individual data and artificial intelligence calculation, to make the position of the dot in the three-dimensional airway model match the actual position of the airway tool 50 in the patient's airway. Thus, when the airway tool 50 moves in the airway and lungs, the position of the airway tool 50 can be observed in real time through the display unit 40, solving the problems that the endoscope cannot reach the deep part of the airway and lungs and cannot intuitively judge the position of the airway tool 50.

[0030] As Figure 3 shown, after the dot is matched with the three-dimensional airway model, calibration is performed through the following process:

[0031] St50. Control the airway tool 50 to move in a certain distance, and judge the scale value of the airway tool 50 corresponding to the patient's glottis opening through the endoscope.

[0032] St60. The main control unit 10 judges the distance of the dot from the glottis opening of the model as the calibration distance through the three-dimensional airway model.

[0033] St70. The main control unit 10 adjusts the diameter of the dot to the difference between the calibration distance and the scale value.

[0034] After the distance of the dot in the three-dimensional airway model is matched with the actual position of the airway tool 50 in the patient's body, calibration is performed through the above process. When there is a difference, the error is eliminated by changing the diameter of the dot, so that the doctor knows the position accuracy of the dot.

[0035] The main control unit 10 is also connected to an anesthesia machine for obtaining the airway pressure and waveform of the anesthesia machine, as well as the end-tidal carbon dioxide waveform, and displaying them on the display unit 40. After calibration, the doctor can observe the airway data at the position where the dot is located, as well as the current airway pressure and waveform of the anesthesia machine, and the end-tidal carbon dioxide waveform on the display unit 40, so as to assist the doctor in judging the data changes caused by the change of the position of the airway tool 50.

[0036] The main control unit 10 controls the display unit 40 to display a panoramic view of any angle of the three-dimensional airway model through the panoramic option; controls the display unit 40 to display any local view of the three-dimensional airway model through the local option; controls the display unit 40 to display any number of panoramic views and any number of local views through the multi-view option. It can perform intelligent panoramic or multi-angle display of the three-dimensional model, and can also perform intelligent multi-angle, multi-dimensional and even panoramic display and prompt for local positions such as abnormal openings in the right upper lung, and prompt the specific lung lobe and lung segment. Thus, doctors can judge the position of the airway tool 50 from multiple angles.

[0037] It also includes a central airway data monitoring center 60, which is used to connect to each main control unit 10 and retrieve the three-dimensional airway data and operation records of any main control unit 10. There are multiple main control units 10 for different doctors to use. The central airway data monitoring center 60 is connected to each main control unit 10 and can retrieve the three-dimensional airway model established by a certain main control unit 10 and the surgical operations performed on it. During the operation, the surgical methods, such as mediastinal surgery or lobectomy, are displayed simultaneously, which is convenient for senior doctors and department management personnel to monitor and manage according to the airway data. After the operation, the central airway data monitoring center 60 stores all the airway data, airway three-dimensional models and operation records processed by the main control units 10, so that the operations of doctors can be evaluated after the operation, and classic cases can be selected to share and learn for doctors.

[0038] It also includes a handheld device that establishes remote communication with the central airway data monitoring center 60. The handheld device is used to remotely view the data in the central airway data monitoring center 60. If the observation of the airway tool 50 (such as single-lumen tracheal catheter, double-lumen tracheal catheter, bronchial blocker, laryngeal mask, etc.) and the anchor point of the positioning position change, the main control unit 10 will give a prompt and alarm, and upload the changed data to the central airway data monitoring center 60. At the same time, the prompt and alarm will also be sent to the handheld devices of the in-room anesthesia personnel, senior anesthesiologists and anesthesia department management personnel.

[0039] A computer device includes a memory and a processor. The memory stores an intelligent multi-mode positioning and early warning system combining artificial intelligence with airway tools, and the processor executes the intelligent multi-mode positioning and early warning system combining artificial intelligence with airway tools.

[0040] A computer-readable storage medium stores an intelligent multi-mode positioning and early warning system combining artificial intelligence with airway tools.

[0041] The beneficial effects of this application include: 1. The main control module of this application accesses artificial intelligence for data analysis, making the visualization of the improved three-dimensional airway model more real-time.

[0042] 2. The main control module uses artificial intelligence to intelligently display the panoramic airway and multi-angle images on the display unit 40, enabling doctors to have a more comprehensive understanding of the situation of the airway tool 50 and making it more comfortable for doctors to use.

[0043] 3. Through the visual real-time display of the display unit 40 and the combination of the positionable probe 51 with artificial intelligence + three-dimensional reconstruction, real-time progress, warnings, and prompts are obtained, making it safer.

[0044] 4. Using the glottis as an anchor point and combining individualized data and artificial intelligence calculations, real-time intelligent multi-dimensional and multi-angle displays are obtained. At the same time, the airway tool 50 is marked with recognizable scales, and the video can be recognized and processed by artificial intelligence to obtain position information, making it more accurate.

[0045] 5. There is an interactive connection between the scanning unit 20, the modeling unit 30, the display unit 40, the airway tool 50, and the central airway data monitoring center 60, making the intelligence more thorough and comprehensive.

[0046] 6. The modeling unit 30 obtains the airway "Pangu model" through machine learning, and the system is better improved. The performance can be further enhanced.

[0047] 7. Transmit the airway management-related data to the central airway data monitoring center 60, and at the same time display the surgical procedures, such as mediastinal surgery or lobectomy, to facilitate better monitoring and management by senior doctors and department managers based on the airway data. The monitoring and management are more efficient.

[0048] 8. At the same time, prompts and alarms will also be sent to the handheld terminal devices of the in-room anesthesiologists, senior anesthesiologists, and anesthesiology department managers, and the surgical procedures will be displayed simultaneously during the prompts and alarms, making it more timely and accurate.

All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
