Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary devices, in particular to an integrated single-lung ventilation visual laryngeal mask. BACKGROUND

[0002] In clinical anesthesia and airway management, laryngeal mask is a widely used ventilation tool, which is suitable for airway management of patients undergoing general anesthesia, and can also be used for endoscopic resection of tracheal tumor or combined with bronchial occluder to achieve single-lung ventilation. However, the existing laryngeal mask has obvious limitations in the following clinical scenarios.

[0003] Single-lung ventilation switching difficulty: In tracheal tumor resection, if intraoperative bleeding or large tumor affects ventilation, the traditional laryngeal mask cannot be quickly converted to single-lung ventilation mode, which may lead to insufficient ventilation and endanger patient safety.

[0004] Tumor shedding risk: After tracheal tumor resection, if the tumor falls off, the traditional laryngeal mask cannot effectively block it from falling into the deep bronchus, increasing the risk of surgery.

[0005] Air leakage during lung inflation operation: In thoracic surgery, when the traditional laryngeal mask is combined with the occluder for single-lung ventilation, the lung inflation operation (such as lung recruitment) is prone to air leakage due to poor sealing of the laryngeal mask, affecting the lung inflation effect.

[0006] Insufficient visualization: The existing visual laryngeal mask usually only provides observation at the glottis, and cannot monitor the position of the bronchial catheter in real time, resulting in inaccurate positioning of single-lung ventilation. SUMMARY

[0007] In view of the deficiencies of the prior art, the present application provides an integrated single-lung ventilation visual laryngeal mask, which solves the problems mentioned above.

[0008] To achieve the above purpose, the present application realizes the following technical scheme: an integrated single-lung ventilation visual laryngeal mask, comprising a visual laryngeal mask body, a laryngeal mask ventilation interface and a visual laryngeal mask cuff are arranged on the outer side of the visual laryngeal mask body, an inflation valve is arranged on the visual laryngeal mask cuff, and a bronchial ventilation tube inlet is arranged at the extension end of the visual laryngeal mask body.

[0009] Further comprising a bronchial catheter integrated in the laryngeal mask body, the front end of the bronchial catheter is provided with a bronchial cuff and a bronchial ventilation interface, and the front end of the bronchial cuff is provided with a bronchial ventilation end.

[0010] A tumor anti-shedding cuff is arranged at the proximal end of the bronchial catheter, which is independent of the bronchial cuff and is controlled by an anti-shedding cuff valve.

[0011] A split-screen display screen synchronously displays images from the laryngeal mask video assembly and the bronchial catheter miniature camera.

[0012] Furthermore, the visual laryngeal mask body is also provided with an angle-adjustable video observation window and a matching fixer and regulator.

[0013] Furthermore, the visual laryngeal mask body is also provided with a gastrointestinal decompression tube insertion channel and a video component insertion channel.

[0014] Furthermore, the bronchial tube includes a micro-camera insertion channel and a depth fixer, and the bend is designed to adapt to the anatomical structure of the trachea. The micro-camera insertion channel is plugged with the bronchial tube micro-camera.

[0015] Furthermore, the independently inflated bronchial cuff valve is connected to the bronchial cuff and is an anti-drop cuff valve.

[0016] Furthermore, the visual laryngeal mask body is also provided with an elastic bronchoscope operation channel port and a cover cap, and the bronchial tube is provided with a fixing component.

[0017] Furthermore, the fixing assembly includes a tightening fixer and a soft plug.

[0018] Furthermore, the single / double lung ventilation mode conversion is achieved by switching the laryngeal mask ventilation interface and the bronchial ventilation interface; during tracheal tumor resection, the inflated anti-falloff cuff forms a physical barrier to prevent the tumor from falling off; and selective lung inflation of the target lung lobe is performed through the bronchial tube.

[0019] Beneficial effects

[0020] The present invention has the following beneficial effects:

[0021] This integrated single-lung and double-lung ventilation visual laryngeal mask achieves rapid and stable single-lung / double-lung ventilation mode conversion through the collaborative design of the built-in bronchial tube and the laryngeal mask body, solving the problems that traditional laryngeal masks cannot meet emergency ventilation needs during surgery and cannot prevent tracheal tumors from falling off and falling into the deep bronchi after tracheal tumor resection.

[0022] The independent anti-fall cuff can be inflated immediately after tumor resection to form a physical barrier, effectively preventing the tumor from falling into the deep bronchus and reducing the risk of secondary surgery.

[0023] Integrate channels for gastrointestinal decompression, bronchoscopy, etc. to avoid the insertion of additional instruments during surgery, reduce airway damage and operation time.

[0024] The laryngeal mask camera monitors the glottis and tumor position in all directions through the adjustable observation window, and the bronchial tube micro-camera provides real-time feedback on the situation in the bronchus, guiding the precise insertion of the tube into the target bronchus.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] See also Figure 1-4An embodiment of the present invention provides a technical solution: an integrated single-lung and double-lung ventilation visual laryngeal mask. This embodiment provides an integrated single-lung and double-lung ventilation visual laryngeal mask, including a visual laryngeal mask body 4: made of medical-grade silicone material, its mask bag 4 can fit the patient's throat, and the sealing is adjusted by the inflation valve 7.

[0034] The bronchial tube 12 is embedded in the laryngeal mask body, and the front end extends to the bronchial tube 12. The bronchial tube 12 is provided with a bronchial cuff 2 and a tumor anti-falling cuff 3, which are independently controlled by the bronchial cuff inflation valve 15 and the tumor anti-falling cuff inflation valve 13 respectively.

[0035] The bronchial tube micro camera 23 is installed through the video component into the visual laryngeal mask video component insertion channel 6 and connected to the angle adjuster 21, so that the glottis and tracheal entrance can be observed;

[0036] The micro camera 23 at the end of the bronchial tube 12 is located on one side of the curved bronchial tube 22 and is fixed through the bronchial tube micro camera insertion channel 24 to locate the position of the bronchial tube 12.

[0037] The split-screen display 11 displays dual images of the laryngeal mask body 4 and the endobronchial tube 12 in real time, assisting in accurate intubation.

[0038] In the double-lung ventilation mode, the laryngeal mask airway interface 9 is connected to the anesthesia machine, and the laryngeal mask airway bag is inflated to form a seal;

[0039] In the single-lung ventilation mode, the bronchial tube 12 is inserted into the target bronchus, the cuff 2 is inflated, and air is supplied through the bronchial ventilation port 14;

[0040] In the anti-falling mode, during tracheal tumor resection, the tumor anti-falling cuff 3 forms a barrier to prevent the tumor from falling into the deep bronchus.

[0041] Example 1: Optimization of lung inflation operation and air leakage prevention design:

[0042] To address the problem of air leakage during lung inflation with conventional laryngeal mask airways, the present embodiment has been improved by using a bronchial tube to directly inflate the lungs. After single-lung ventilation, when lung inflation is required, air is injected into the lung on the surgical side through the bronchial tube 12, thereby avoiding air leakage caused by ventilation through the laryngeal mask airway body 4.

[0043] Retract the endobronchial tube and inflate the lungs: If simultaneous inflation of both lungs is required, the endobronchial tube 12 is retracted to the main trachea, and whole-lung ventilation is performed through its endobronchial ventilation interface 14, using the tube's own sealing to reduce air leakage.

[0044] The bronchial tube 12 of this embodiment uses a detachable bronchial end camera 23 to be installed through the bronchial tube micro-camera insertion channel 24. After use, it can be disinfected with ethylene oxide and reused. The depth fixer 25 has scale marks to adjust the camera insertion depth to adapt to different patients' tracheal lengths.

[0045] Example 2:

[0046] The multi-channel cooperative operation elastic bronchoscope operating channel 8 is inserted into a bronchoscope with a diameter of ≤3.5mm and cooperates with the cap 16 to maintain sealing;

[0047] During the operation, a gastric tube can be inserted into the gastrointestinal decompression channel 5 to drain gastric contents and reduce the risk of reflux. The bronchial tube fixing component ensures the stability of the tube position by tightening the fixator 18 and the soft plug 17 to prevent intraoperative displacement. During tracheal tumor resection, the surgeon uses the split-screen display 11 to simultaneously observe the micro camera 23 of the bronchial tube at the laryngeal mask end to monitor the glottis and tumor resection site. The bronchial end camera 23 confirms the position of the anti-drop cuff 3 to prevent the tumor from falling into the healthy lung.
