Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically provides an intelligent automatic regulation visual intubation flexible bronchoscope tracheal intubation operation training device. Background Technique

[0002] Visual intubation flexible bronchoscope tracheal intubation is a technique assisted by a visual intubation flexible bronchoscope during tracheal intubation operations. The visual intubation flexible bronchoscope usually consists of a mirror body, a light source, an imaging system, a display, etc. The mirror body is slender and flexible, with a micro camera and a light source at the front end. During tracheal intubation, the visual intubation flexible bronchoscope is inserted into the airway through the oral cavity or nasal cavity, and the image inside the airway is collected in real time by the camera and transmitted to the display. Doctors can intuitively observe the anatomical structures inside the airway, such as the glottis, tracheal rings, etc., so as to accurately insert the tracheal catheter into the trachea. Through the visual technique, doctors can clearly see the structures inside the airway and accurately insert the tracheal catheter into the trachea, avoiding intubation failure or complications caused by blind intubation. It is especially suitable for patients with difficult airways. Visual intubation flexible bronchoscope tracheal intubation can reduce the damage to the airway mucosa and reduce the incidence of complications such as bleeding, laryngeal edema, and vocal cord injury.

[0003] For the existing training operations of visual intubation flexible bronchoscope tracheal intubation, operation practice is generally carried out using a mannequin or animal model. Trainees repeatedly practice operations such as the insertion technique of the visual intubation flexible bronchoscope, the adjustment of the lens, the recognition of the glottis, and the pushing of the tracheal catheter on the model, familiarize themselves with the operation process, and master the correct techniques and forces. The existing operation training devices lack an automatic regulation function, cannot accurately simulate various situations in the real scene, and are also difficult to conduct real-time evaluation and feedback on the operations of trainees, affecting the training effect. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent automatic regulation visual intubation flexible bronchoscope tracheal intubation operation training device to solve the problems in the above background technique that the existing operation training devices lack an automatic regulation function, cannot accurately simulate various situations in the real scene, and are also difficult to conduct real-time evaluation and feedback on the operations of trainees, affecting the training effect.

[0005] To achieve the above object, the present invention provides the following technical solutions: An intelligent automatic regulation visual intubation flexible bronchoscope tracheal intubation operation training device, including a support bottom plate, on the upper surface of which a simulation model is fixedly connected. Above the simulation model, a training intubation tube is provided. One end of the training intubation tube is externally provided with a display screen, and a gyroscope sensor is fixedly connected to the surface of the training intubation tube. The upper surface of the support bottom plate is fixedly connected with a liquid storage tank. The upper surface of the liquid storage tank is fixedly connected with a feeding pipeline, and a pumping pump is installed on the upper surface of the liquid storage tank. A guiding pipe is fixedly installed on the surface of the pumping pump. A simulation inner cavity is opened on the surface of the simulation model. A speed sensor is fixedly connected to the top surface at one end of the simulation inner cavity, and a cleaning nozzle is fixedly connected to the top surface at the other end of the simulation inner cavity. A first installation groove is opened on the bottom surface of the simulation inner cavity, and a second installation groove is also opened on the bottom surface of the simulation inner cavity. Transmission gears are installed on the inner walls of both the first installation groove and the second installation groove. A regulating handle is connected to the rear surface of the simulation model. A first toothed plate is arranged on the inner wall of the first installation groove, and a cleaning baffle is fixedly connected to the upper surface of the first toothed plate. A cleaning slot is opened on the upper side surface at the upper end of the first installation groove. A linkage blocking mechanism is installed in the second installation groove, which drives the two transmission gears to rotate synchronously through a transmission chain, so as to facilitate the transmission gears to drive the second toothed plate and the blocking slide plate to slide upward for blocking.

[0006] Preferably, one end of the guiding pipe penetrates through the side surface of the simulation model, and the guiding pipe is designed in an L shape. The vertical structure of the guiding pipe penetrates through the top surface at one end of the simulation inner cavity, and a spraying nozzle is fixedly connected to the lower end of the vertical structure of the guiding pipe.

[0007] Adopting the above technical solution, the L-shaped guiding pipe can more flexibly adapt to the structure of the simulation model. One end penetrates through the side surface of the simulation model, which can conveniently extract the liquid in the liquid storage tank through the pumping pump and transport it to the simulation inner cavity. Its vertical structure penetrates through the top surface at one end of the simulation inner cavity, enabling the liquid to accurately reach the designated position and ensuring the accuracy of liquid transportation. The spraying nozzle fixedly connected to the lower end of the vertical structure of the guiding pipe can spray the liquid at a certain angle and range, so that the liquid can be evenly distributed in a specific area of the simulation inner cavity, which can better meet the functional requirements of the training device and improve the authenticity and effect of the training.

[0008] Preferably, the speed sensor is designed in a long strip shape. The two cleaning nozzles are symmetrically arranged, and the cavity of the cleaning nozzle penetrates through the surface of the simulation model and is connected to the water inlet pipe.

[0009] With the above technical solution, the elongated design can cover a relatively large width range of the simulated inner cavity, enabling a more comprehensive and accurate measurement of the speed of the training cannula moving within the simulated inner cavity. Compared with sensors of ordinary shapes, the elongated sensor can obtain speed information at more position points, reducing measurement errors, providing more accurate operation feedback for the trainer, and helping to improve the training effect. The two cleaning nozzles are symmetrically arranged to clean the simulated inner cavity from different angles, ensuring the uniformity of cleaning. Whether it is the top, sides, or bottom of the simulated inner cavity, it can be covered by the liquid sprayed from the cleaning nozzles, effectively removing impurities, residual liquid, or other pollutants within the simulated inner cavity, maintaining the cleanliness of the simulated environment, and providing good conditions for subsequent training operations.

[0010] Preferably, the first installation groove communicates with the second installation groove, and both the first installation groove and the second installation groove are rotationally connected to the conduction gears. One end of the rotating shafts of the two conduction gears is provided with a sprocket.

[0011] With the above technical solution, the two installation grooves communicate with each other and are rotationally connected to the conduction gears, enabling the two conduction gears to cooperate with each other. The sprockets provided at one end of the rotating shafts can be linked by installing a transmission chain to ensure their synchronous rotation. Such a design can ensure that the first toothed plate in the first installation groove and the second toothed plate in the second installation groove can move in coordination, thereby driving the cleaning baffle and the blocking slide plate to act in a predetermined manner. The combination of the rotationally connected conduction gears, sprockets, and transmission chain can achieve relatively efficient power transmission, improving the accuracy and stability of the transmission.

[0012] Preferably, the adjusting handle is rotationally connected to the simulation model. The rotating shaft of the adjusting handle penetrates the surface of the simulation model, and the rotating shaft of the adjusting handle is fixedly connected to the rotating shaft of the conduction gear in the first installation groove.

[0013] With the above technical solution, by rotating the adjusting handle, the trainer can directly and precisely control the rotation of the conduction gear. Since there is a transmission relationship between the conduction gear and other components, this precise control can achieve accurate adjustment of the positions and actions of the relevant components within the simulated inner cavity. Setting the adjusting handle outside the simulation model is convenient for the trainer to operate at any time during the use of the device. By simply rotating the adjusting handle to control the internal mechanism, this greatly improves the convenience and efficiency of the operation, making the training process more smooth and reducing training interruptions or mistakes that may be caused by complex operations.

[0014] Preferably, the first toothed plate is slidably connected to the first installation groove, and a toothed block is provided on the side surface of the first toothed plate. The first toothed plate is meshed with one side conduction gear through the toothed block.

[0015] With the above technical solution, when the transmission gear rotates, through meshing with the tooth blocks on the side surface of the first toothed plate, the rotation can be converted into the linear sliding of the first toothed plate in the first installation groove. This meshing transmission method has high precision, which can ensure that the first toothed plate moves accurately according to the design requirements, and then precisely control the positions of components such as the cleaning baffle plate connected to the first toothed plate. The sliding connection method between the first toothed plate and the first installation groove provides stable support and guidance for the first toothed plate. During the process of the transmission gear driving the first toothed plate to move, the first installation groove can limit the movement direction of the first toothed plate, preventing it from shaking or deviating, ensuring the stability and reliability of the entire transmission process, making the actions of components such as the cleaning baffle plate more stable, contributing to improving the simulation effect and service life of the training equipment. This connection method is relatively simple and is easy to disassemble and install during equipment maintenance or component replacement. If the first toothed plate, transmission gear or first installation groove is worn, damaged, etc., the staff can conveniently disassemble and replace the relevant components, reducing the maintenance cost and difficulty of the equipment, being beneficial to the long-term stable operation of the equipment, and ensuring the normal development of training work.

[0016] Preferably, the cleaning slot is inclined, and the cavity of the cleaning slot penetrates through the rear surface of the simulation model, and the cavity of the cleaning slot is communicated with the sewage pipe.

[0017] With the above technical solution, the inclined design can utilize the gravity effect to make the sewage, impurities, etc. in the simulation model flow more smoothly along the inclined surface of the cleaning slot during the cleaning process, quickly gather in the sewage pipe and be discharged, avoiding the accumulation of sewage in the model, improving the cleaning efficiency, and keeping the inside of the simulation model clean. The inclined cleaning slot can reduce the possibility of impurities in the sewage precipitating and adhering, reducing the risk of the cleaning slot and the sewage pipe being blocked. The impurities are not easy to stay under the action of gravity and can be discharged together with the sewage, ensuring the smoothness of the drainage system, being beneficial to the long-term stable operation of the simulation model, and facilitating the staff to inspect, clean and maintain the cleaning slot and the sewage pipe.

[0018] Preferably, the linkage blocking mechanism includes a transmission chain, the transmission chain is installed on the outer surface of the sprockets of two transmission gears, a second toothed plate is arranged on the inner wall of the second installation groove, and a blocking slide plate is fixedly connected to the upper surface of the second toothed plate.

[0019] With the above technical solution, the drive chain is installed on the outer surfaces of the sprockets of two conduction gears, which can ensure the synchronous rotation of the two conduction gears. When one conduction gear rotates, the other conduction gear will also rotate at the same speed and in the same direction driven by the drive chain. In this way, the first toothed plate and the second toothed plate respectively meshing with the two conduction gears can achieve synchronous linear motion, and further enable the cleaning baffle and the blocking slide plate to move synchronously, realizing the linkage function. The meshing drive mode between the conduction gear and the toothed plate can accurately control the position of the blocking slide plate. Due to the certain precision of the tooth profile design of the gear and the toothed plate, it can be ensured that the blocking slide plate moves along a predetermined trajectory and distance during the transmission process. The inner wall of the second installation groove is provided with the second toothed plate, and the upper surface of the second toothed plate is fixedly connected with the blocking slide plate. This structural design makes the movement of the blocking slide plate more stable.

[0020] Preferably, the second toothed plate is slidably connected to the second installation groove. Tooth blocks are arranged on the surface of the second toothed plate, and the second toothed plate is meshed with one side conduction gear through the tooth blocks.

[0021] With the above technical solution, the second toothed plate is meshed with the conduction gear through the tooth blocks. The rotation of the conduction gear can be accurately converted into the linear sliding of the second toothed plate in the second installation groove. The sliding connection between the second toothed plate and the second installation groove provides stable support and guidance for the second toothed plate, and the meshing connection enables the conduction gear to evenly transmit force to the second toothed plate.

[0022] Preferably, an adjusting air pump is embeddedly installed on the bottom surface of one side of the simulation inner cavity, and a simulation airbag is installed at the upper end of the adjusting air pump.

[0023] With the above technical solution, by inflating and deflating the simulation airbag through the adjusting air pump, the expansion and contraction of the airbag during human breathing can be simulated, creating a dynamic environment similar to the human trachea or respiratory tract for the simulation inner cavity. When the trainer performs operations such as tracheal intubation, they can feel a more realistic physiological state, improving the fidelity of the training. The presence of the simulation airbag allows the trainer to feel key elements such as airway resistance and pressure changes during the operation process. The adjusting air pump can accurately adjust the pressure and inflation volume of the simulation airbag according to different training requirements and simulation scenarios.

[0024] Compared with the prior art, the beneficial effects of the present invention are: This intelligent automatic regulation visual intubation flexible bronchoscope tracheal intubation operation training device:

[0025] 1. The device is provided with a spraying nozzle and a cleaning nozzle. When the device works, the simulated mucus is introduced into the simulated cavity through the extraction pump, the feed pipe, the liquid storage tank and the spraying nozzle, so as to simulate the real environment inside the human body, increase the humidity and resistance in the airway, simulate the situation of having secretions in the real airway, test the ability of trainees to clean the secretions and continue intubation under such circumstances, improve the simulation training effect of the device, and after the training, the cleaning water is sprayed out through the cleaning nozzle, which is convenient for cleaning the simulated liquid and increases the convenience of cleaning and maintenance of the device;

[0026] 2. The device is provided with a cleaning baffle and a blocking slide plate. When the device works, by rotating the adjusting handle to drive the conduction gear on one side to rotate, the conduction gear on this side drives the first toothed plate and the cleaning baffle to descend, which is convenient for sewage to be guided into the cleaning slot, so as to discharge and clean the sewage, increasing the convenience of cleaning. The two conduction gears rotate simultaneously through the transmission chain, and the conduction gear on the other side will drive the second toothed plate and the blocking slide plate to rise, which is convenient for the blocking slide plate to block the simulated cavity without simulated liquid distribution, preventing the sewage from flowing randomly and increasing the cleaning efficiency;

[0027] 3. The device is provided with an adjusting air pump and a simulated airbag. When the device works, the adjusting air pump inflates and deflates the simulated airbag, causing the simulated airbag to deform and making the local part of the simulated cavity narrower, simulating the pathological state of airway stenosis. This simulation can be dynamically adjusted according to the operation level and training stage of the trainees, gradually transitioning from mild stenosis to severe stenosis, improving the difficulty and pertinence of the training.

When using this device, firstly, the simulated liquid in the liquid storage tank 6 is guided from the guide tube 9 to the spray nozzle 10 through the extraction pump 8, so that the spray nozzle 10 sprays the simulated liquid into the simulation inner cavity 11 to simulate the real environment, and then the training cannula 3 is inserted into the simulation inner cavity 11 for operation training. Through the gyroscope sensor 5 and the speed sensor 12, the action data of the trainee during the operation process is collected in real time, including the amplitude, speed, strength and other information of the insertion, rotation and pulling of the soft mirror, which can accurately reflect the trainee's operation techniques and habits.

The first tooth plate 17 drives the cleaning baffle 18 to descend, thereby exposing the cleaning slot 19. At the same time, the second tooth plate 22 drives the blocking slide plate 23 to slide upward, so that the blocking slide plate 23 abuts against the top surface of the simulated inner cavity 11 to block the sewage generated by subsequent cleaning.
