Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an intelligent monitoring type lung isolation ventilation device and a monitoring method. Background Art

[0002] In clinical work, artificial airways are conventionally established by tracheal intubation for ventilation, including unilateral lung isolation ventilation during thoracic surgery. As the most commonly used tool for assisting patients in ventilation with an artificial airway, tracheal intubation can quickly and effectively establish an artificial ventilation airway. However, due to the differences in human anatomical structures and the changes in body positions during the surgical process, difficulties in tracheal intubation, catheter displacement, and air leakage often occur. For patients who require lung isolation ventilation surgery such as lung cancer, esophageal cancer, and mediastinal tumors, during the clinical intubation process, the proximal end of the bronchial intubation needs to be placed into one side of the patient's lung, and positioning and blocking are implemented at the bronchial orifice below the tracheal carina. Finally, the bronchial catheter cuff is inflated, fixed, and blocked, blocking and isolating the affected lung, providing ventilation function for the healthy lung, preventing the affected lung from contaminating the healthy lung, and ensuring the surgical operation position required by the affected lung.

[0003] In addition, there are usually the following several methods for clinical application of bronchial intubation for one-lung ventilation: (1) Traditional bronchial blocker: Judging whether the blocking is successful by auscultating the breath sounds of both lungs. After the doctor successfully performs tracheal intubation, the affected lung is blocked, and the blocking is judged to be successful by auscultating the breath sounds of both lungs until there is no undulation of the chest wall and the breath sounds disappear in the affected lung. This blocking process is a blind probing operation, relying entirely on clinical experience, with great difficulty and a high failure rate; (2) Fiberoptic bronchoscope-assisted judgment: Using a fiberoptic bronchoscope to assist the bronchial blocker in blocking the affected lung. Although the operation can be carried out under the guidance of visual technology, improving the blocking success rate, during the surgical process, body position changes and surgical operations are likely to cause the displacement of the blocker cuff, resulting in the failure of lung isolation and air leakage, and it is necessary to use a fiberoptic bronchoscope again to assist in blocking the affected lung, bringing great trouble to clinical work; (3) Application of a bronchial visual blocker: Although the visual bronchial blocker is simple to operate and can monitor the displacement function of the blocker in real time, it cannot timely judge the blocking effect of the blocker, the air leakage caused by the displacement of the cuff position during the operation, and the pressure change of the blocker cuff.

[0004] The Chinese utility model patent with the announcement number CN216566247U discloses a catheter-visible bronchial occluder, which includes an occluding tube, a tracheal catheter, a micro camera, a visible handle, a display device and a video connection cable; the occluding tube and the inclined front end tube wall of the tracheal catheter are connected, the tube body is designed with double cavities, and the head end has an occluding tube balloon connected to an occluding tube inflation valve to inflate and deflate the occluding tube balloon. Through the visualization positioning of the occluder, intraoperative oxygen supply is carried out while continuous visualization monitoring is performed. Although visualization occlusion is achieved, the connection between the occluding tube and the tracheal catheter cannot quickly and portably adjust the position of the occluding cuff after displacement, and cannot timely control and correct the displacement risk during the process of lung isolation ventilation. Therefore, during the occlusion process of the affected lung, while ensuring the occlusion effect, it is necessary to monitor the intubation displacement and air leakage in real time and correct them in a timely and effective manner to further improve the success rate of the lung isolation ventilation operation and ensure the safety of patients. Summary of the Invention

The distal end of the ventilation tube 2 is connected with an adapter tube 27, and the distal end of the adapter tube 27 is connected with the multi-functional joint 3. As Figure 5 and Figure 6 shown, the multi-functional joint 3 includes a ventilation four-way joint 31 and a drainage branch, a blocking side branch and a ventilation side branch provided on the ventilation four-way joint 31.

By setting the protective sleeve, the occurrence of nosocomial infection can be effectively prevented, and the clinical use frequency and time of the drainage tube 321 can be increased. The drainage tube 321 is arranged in the ventilation cavity 211 and passes through the drainage tube fixing cap 33 and is connected with the distal drainage joint 323; the drainage tube fixing cap 33 is used for directional sliding and fixing the drainage tube 321, that is, sliding the drainage tube 321 can realize the drainage function of the proximal end of the ventilation cavity 211 and the accumulated fluid at the carina of the airway. The drainage joint 323 is connected with the sealing cover 324. The proximal end of the drainage tube 321 is provided with a drainage port. Specifically, the drainage port can be set at a position where the proximal end ≤ 15 mm. The drainage port includes an asymmetrically arranged first drainage port 3211, a second drainage port 3212 and a third drainage port 3213. An artificial airway is effectively established through the ventilation tube 2 to realize the functions of visible intubation of the airway, oxygen supply ventilation and intraoperative visible monitoring. Through the multi-functional joint 3, the blocking tube 1 and the drainage device 32 are slidably adjusted and stably positioned, so that the blocking tube 1 can be adjusted conveniently and timely and the accumulated fluid can be drained, and at the same time, the distal side branch is stabilized to ensure the stability of the device.

[0026] The blocking tube 1 is made of nylon material and has a Shore hardness of greater than or equal to 100 degrees; the ventilation tube 2 is made of PVC or TPU material, and the Shore hardness ranges from 70 to 95 degrees; the drainage tube 3 is made of PVC material, and the Shore hardness ranges from 50 to 80 degrees. By differentiating the blocking tube 1 and the ventilation tube 2 in terms of materials and structural strength, the toughness and anti-bending ability of the blocking tube are effectively improved, the anti-displacement effect is enhanced, and it is ensured that the flexibility of the ventilation tube is stronger than that of the blocking tube, with higher plasticity and better ventilation effect; at the same time, the inner diameter of the blocking tube 1 is smaller, which can reduce intubation injury and continuous compressive injury.

[0027] The intelligent monitoring device 4 is connected to the visual control device 26. The visual control device 26 includes a data line 261, a data connector 262, and a regulation handle 263.

The intelligent monitoring device 4 includes a control main board, and the control main board is respectively connected to a display and a second wireless transmission module 41. The first wireless transmission module is connected to the second wireless transmission module 41.

[0028] In this embodiment, as Figure 8 shown. During specific use, the clinician first inserts the proximal end of the ventilation tube 2 into the patient's airway and fixes the position through the fixing cuff 23. Then, the proximal end of the blocking tube 1 is inserted into the ventilation cavity 211 of the ventilation tube 2, placed at a specified position in the patient's bronchus, and the blocking tube 1 is fixed by the blocking tube fixing cap 34 on the multi-functional joint 3 to prevent its distal end from moving. The affected side of the lung is isolated and blocked by the blocking cuff 12. The camera 22 collects the images of the blocking cuff 12 and the bronchial carina in real time, and transmits the collected data to the intelligent monitoring device 4 through the visual control device 26. The intelligent monitoring device 4 displays the collected images in real time and monitors the air leakage and displacement of the blocking cuff 12. When the camera 3 is soiled and blocks the line of sight and cannot collect normally, it is flushed through the flushing device 25. After the intelligent monitoring device 4 monitors that the blocking cuff 12 has shifted, the blocking tube 1 is adjusted by adjusting the blocking tube fixing cap 34. At the same time, the blocking cuff 12 is further fixed by inflating and deflating through the first inflating device 13, and the blocking cuff 12 is adjusted in a timely manner. The drainage tube 321 is slid by adjusting the drainage tube fixing cap 33 to realize the drainage of the proximal end of the ventilation cavity 211 and the effusion of the bronchial carina, avoiding the risks of intraoperative lung isolation displacement and aspiration.

[0029] The ventilation device of the present invention fixes the position of the ventilation tube 2 through the fixed cuff 23, arranges the blocking tube 1 in the ventilation cavity 211 of the ventilation tube 2, collects the images inside the trachea through the camera 3, and realizes the real-time monitoring of the CO2 gas concentration in the diseased lung through the gas monitoring cavity 113. It can quickly guide the tracheal catheter for intubation and correct it in time after displacement and air leakage, reduce the damage during the intubation process of the airway mucosa, improve the success rate of intubation and bronchial occlusion, and can observe the situation of gastroesophageal reflux or airway secretions in real time to ensure the patency of the airway.

[0030] As Figure 9 shown, the present invention also provides an intelligent monitoring type lung isolation monitoring method, including the following steps: In this embodiment, a target detection model is constructed. The standard images of the carina structure, the standard images of the occluding cuff, and the standard distance data of the occluding cuff are used to train the target detection model respectively to obtain the trained target detection model. The trained target detection model includes a carina structure model, an occluding cuff model, and a distance model. The carina structure model is used to extract the position characteristics of the carina structure, the occluding cuff model is used to extract the position characteristics of the occluding cuff, and the distance model is used to detect the distance characteristics of the occluding cuff. In this embodiment, as Figure 10 shown, the standard image of the carina structure or the standard image of the occluding cuff is the image of the carina structure or the image of the occluding cuff 12 obtained by the camera 22 when the ventilation device is in the standard position judged by the doctor, and is obtained after processing and annotation. The processing method includes optimizing the image and data enhancement. Annotation is used to obtain the position information of the carina structure and the occluding cuff 12. According to the standard image of the occluding cuff, the distance between the camera 22 and the occluding cuff 12 is annotated to obtain the standard distance data of the occluding cuff. Another implementation is that the standard image of the carina structure, the standard image of the occluding cuff, and the standard distance data of the occluding cuff all come from the historical data set, which will not be elaborated in the present invention.

[0031] Real-time collect the real-time images of the carina structure and the real-time images of the occluding cuff to be monitored, and obtain the real-time distance data of the occluding cuff 12. Analyze the real-time images of the carina structure according to the carina structure model to obtain the carina structure monitoring information, analyze the real-time images of the occluding cuff according to the occluding cuff model to obtain the occluding cuff monitoring information, calculate the distance of the occluding cuff 12 in the real-time images of the occluding cuff according to the distance model to obtain the real-time distance and distance monitoring information of the occluding cuff 12, and comprehensively evaluate the carina structure monitoring information, the occluding cuff monitoring information, and the distance monitoring information to obtain the final monitoring result.

[0032] Specifically, the comprehensive evaluation includes: judging the confidence level of the detected target overlapping position area, comparing and analyzing the candidate box positions of the real-time image of the carina structure obtained by detection with the candidate box positions of the standard image of the carina structure, comparing and analyzing the candidate box positions of the real-time image of the occluding balloon obtained by detection with the candidate box positions of the standard image of the occluding balloon, comparing and analyzing the real-time distance data of the detected occluding balloon 12 with the standard distance data, and determining the final monitoring result. When the final monitoring result exceeds the set threshold, an alarm signal or a prompt alarm message is issued.

[0033] The specific process is as follows. The camera 22 captures the real-time image of the carina structure to be monitored and the real-time image of the occluding balloon in real time, and obtains the real-time distance data of the occluding balloon 12 through the intelligent monitoring device 4. The intelligent monitoring device 4 performs a comparison and analysis on the real-time image of the carina structure collected in real time and the standard image of the carina structure based on the carina structure model, or performs a comparison and analysis on the real-time image of the occluding balloon collected in real time and the standard image of the occluding balloon based on the occluding balloon model, or performs a comparison and analysis on the real-time distance data of the occluding balloon 12 and the standard distance data based on the distance model. When the real-time image of the carina structure or the real-time image of the occluding balloon collected in real time changes compared with the standard image of the carina structure or the standard image of the occluding balloon and does not exceed the set threshold, that is, when the image recognition overlapping area is relatively high, it is judged that there is no displacement and no foreign object enters the field of view; on the contrary, when the change exceeds the set threshold, that is, when the overlapping area is relatively low, it is judged that there is a displacement or a foreign object; or when the real-time data changes compared with the standard data and exceeds the set threshold, the final monitoring result is output and the alarm system is activated to issue an alarm signal or a prompt alarm message to prompt the medical staff to make timely corrections.

[0034] The method of the present invention can monitor the position and distance changes of the occluding tube and the ventilation tube in real time, and give an alarm prompt in real time to guide the clinician to make timely adjustments and correct the risk of displacement during the pulmonary isolation ventilation process in a timely manner.

[0035] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
