Description

Technical Field

[0001] This utility model relates to the field of laryngeal mask device technology, and in particular to a visual laryngeal mask device with pressure detection. Background Technology

[0002] A laryngeal mask airway (LMA) is a medical device used for airway management. It mainly consists of two parts: a ventilation tube and a laryngeal mask. The ventilation tube is usually a hollow tube, with one end connected to equipment such as an anesthesia machine or ventilator, and the other end connected to the laryngeal mask. It is used to deliver oxygen and anesthetic gases and expel the patient's exhaled air. The laryngeal mask is an oval-shaped device similar to a face mask, made of soft materials such as silicone, with an inflatable bladder around the edge. When the laryngeal mask is correctly placed in the patient's larynx, the inflatable bladder can form a seal around the larynx to prevent gas leakage and reflux of stomach contents.

[0003] Traditional manufacturing lacks real-time monitoring capabilities. Due to the lack of sensor monitoring, traditional laryngeal mask devices cannot know the pressure between the laryngeal mask and the larynx in real time. This may lead to excessive pressure, causing damage to the patient's laryngeal tissues, such as compressive ischemia and mucosal rupture. Insufficient pressure may cause the laryngeal mask to not seal properly, leading to the risk of aspiration and seriously threatening the patient's life. Utility Model Content

[0004] The purpose of this invention is to provide a visual laryngeal mask device with pressure detection, which can solve the problem that traditional manufacturing lacks real-time monitoring function. Due to the lack of sensor monitoring, traditional laryngeal mask devices cannot know the pressure of the laryngeal mask in contact with the larynx in real time. This may lead to excessive pressure, causing damage to the patient's laryngeal tissues, such as compressive ischemia and mucosal damage. Insufficient pressure may cause the laryngeal mask to not seal properly, leading to the risk of aspiration and seriously threatening the patient's life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a visual laryngeal mask device with pressure detection, comprising a mask body, an airway tube disposed on one side of the mask body, and a cuff disposed on one side of the mask body. A monitoring component is disposed on the outer side of the cuff, the monitoring component being used to monitor the pressure of the part of the cuff in contact with the patient in real time. An inflation component is connected to one side of the cuff, the inflation component being used to adjust the inflation volume of the cuff according to the monitoring results of the monitoring component.

[0006] In one preferred embodiment, the monitoring component includes a first monitoring agency and a second monitoring agency.

[0007] In a preferred embodiment, the first monitoring mechanism includes a groove formed on the outer side of the sleeve, and multiple sets of first pressure sensors are installed on the inner side of the groove. A cover plate is fixedly connected to one side of each of the first pressure sensors.

[0008] In a preferred embodiment, the cover plate is made of medical-grade silicone.

[0009] In a preferred embodiment, the second monitoring mechanism includes a second pressure sensor, which is mounted on the outside of the sheath, and a rubber sleeve is fixedly connected to the outside of the second pressure sensor.

[0010] In a preferred embodiment, the inflation assembly includes an inflation tube connected to the outer side of one end of the sleeve. A sleeve is connected to the outer side of the end of the inflation tube. A threaded rod is threaded to the inner side of the end of the sleeve. A plug is fixedly connected to the outer side of one end of the threaded rod. The outer side of the plug is in close contact with the inner wall surface of the sleeve.

[0011] In a preferred embodiment, a limiting rod is fixedly connected to the outer side of one end of the sleeve, a motor is mounted on the outer side of the limiting rod, and the outer side of the main shaft of the motor is fixedly connected to the outer side of one end of the threaded rod.

[0012] In a preferred embodiment, a limiting plate is fixedly connected to the outer side of the end of the limiting rod.

[0013] In a preferred embodiment, a vision camera is mounted on the inner side of one end of the sheath.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In use, this utility model connects multiple first pressure sensors through a cover plate for synchronous monitoring, and controls the motor through the monitoring structure of the first pressure sensors to perform inflation and deflation. The multiple first pressure sensors are connected through the cover plate as a single sensor, which can monitor the pressure of the patient's larynx over a wider area. Compared with a single sensor, the large number of first pressure sensors can cover a wider area, ensuring that pressure changes in all parts of the larynx can be accurately captured, greatly improving the comprehensiveness of monitoring and avoiding blind spots. The first pressure sensors and the cover plate are connected to form a whole. When the outer side of the cover plate contacts the patient's larynx, each first pressure sensor can synchronously sense pressure changes and quickly transmit the information. This real-time synchronous feedback mechanism allows the system to react quickly to pressure changes, such as adjusting the motor in time to perform inflation and deflation operations, maintaining stable laryngeal mask pressure, and ensuring patient safety and comfort.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides a technical solution: a visual laryngeal mask device with pressure detection, including a mask body 1, an airway 2 on one side of the mask body 1, and a cuff 3 located on one side of the mask body 1. A monitoring component is provided on the outside of the cuff 3, which is used to monitor the pressure of the part of the cuff 3 in contact with the patient in real time. An inflation component 6 is connected to one side of the cuff 3, which is used to adjust the inflation volume of the cuff 3 according to the monitoring results of the monitoring component. The monitoring component includes a first monitoring mechanism 4 and a second monitoring mechanism 5. The first monitoring mechanism 4 includes a groove 401, which is opened on the outside of the cuff 3. Multiple sets of first pressure sensors 402 are installed on the inside of the groove 401. A cover plate 403 is fixedly connected to one side of the first pressure sensor 402. The cover plate 403 is made of medical silicone.

[0024] In this embodiment, when using the device, the user inserts the cover 1 into the patient's throat. At this time, the monitoring component on the outside of the cuff 3 can perform pressure monitoring. A groove 401 is provided on the outside of the cuff 3, and multiple first pressure sensors 402 are installed on the inside of the groove 401. A cover plate 403 is fixedly connected to one side of the first pressure sensor 402. When the outside of the cover plate 403 contacts the patient's throat, the user can start the motor 605. The motor 605 drives the threaded rod 606 to rotate. Through the threaded connection between the threaded rod 606 and the end of the sleeve 602, the threaded rod 606 and the plug 607 move towards the inside of the sleeve 602, thereby filling the inside of the sleeve 602 with air through the inflation tube 601 into the inside of the cuff 3, causing the cuff 3 to expand and continuously pressurize the first pressure sensors 402. Multiple first pressure sensors 402 are connected through the cover plate 403 for simultaneous monitoring. The system monitors pressure in the laryngeal mask and controls the motor 605 via the monitoring structure of the first pressure sensor 402 to perform inflation and deflation. Multiple first pressure sensors 402 are connected by a cover plate 403, forming a single sensor that can monitor pressure in the patient's larynx over a wider area. Compared to a single sensor, the numerous first pressure sensors 402 can cover a wider area, ensuring that pressure changes in all parts of the larynx can be accurately captured, greatly improving the comprehensiveness of monitoring and avoiding blind spots. The first pressure sensors 402 and the cover plate 403 are connected to form a whole. When the outer side of the cover plate 403 contacts the patient's larynx, each first pressure sensor 402 can synchronously sense pressure changes and quickly transmit the information. This real-time synchronous feedback mechanism allows the system to react quickly to pressure changes, such as adjusting the motor 605 in a timely manner to perform inflation and deflation operations, maintaining stable laryngeal mask pressure, and ensuring patient safety and comfort.

[0025] Example 2, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The second monitoring mechanism 5 includes a second pressure sensor 501, which is installed on the outside of the sheath 3. A rubber sleeve 502 is fixedly connected to the outside of the second pressure sensor 501. The inflation assembly 6 includes an inflation tube 601, which is connected to the outside of one end of the sheath 3. A sleeve 602 is connected to the outside of the end of the inflation tube 601. A threaded rod 606 is threadedly connected to the inside of the end of the sleeve 602. A plug 607 is fixedly connected to the outside of one end of the threaded rod 606. The outside of the plug 607 is in close contact with the inner wall of the sleeve 602. A limit rod 603 is fixedly connected to the outside of one end of the sleeve 602. A motor 605 is installed on the outside of the limit rod 603. The outside of the main shaft of the motor 605 is fixedly connected to the outside of one end of the threaded rod 606. A limit plate 604 is fixedly connected to the outside of the end of the limit rod 603. A vision camera 7 is installed on the inside of one end of the sheath 3.

[0026] In this embodiment, multiple second pressure sensors 501 are distributed and covered with a thin silicone sleeve 502. The motor 605 is controlled by averaging the monitoring results of multiple second pressure sensors 501 under pressure. The distributed arrangement of the multiple second pressure sensors 501 allows for pressure data collection from different locations. Since the pressure distribution in the throat may be uneven, the data from a single second pressure sensor 501 is limited. By averaging the monitoring results of multiple second pressure sensors 501, the deviation caused by local pressure fluctuations can be effectively eliminated, making the final data closer to the overall true pressure level of the throat and significantly improving the accuracy of the pressure monitoring data. A vision camera 7 is installed on one side of the sleeve 3 for real-time observation. The first pressure sensor 402 and the second pressure sensor 501 can be Honeywell 1865-03G-LDN, a series suitable for applications applying force through a flexible membrane, which is compatible with the pressure monitoring principle of this device.

[0027] Working principle: When using the device, the user inserts the cover 1 into the patient's throat. At this time, the monitoring component on the outside of the cuff 3 can monitor the pressure. The outside of the cuff 3 has a groove 401, and multiple first pressure sensors 402 are installed inside the groove 401. A cover plate 403 is fixedly connected to one side of the first pressure sensor 402. When the outside of the cover plate 403 contacts the patient's throat, the user can start the motor 605. The motor 605 drives the threaded rod 606 to rotate. Through the threaded connection between the threaded rod 606 and the end of the sleeve 602, the threaded rod 606 and the plug are rotated. The head 607 moves toward the inside of the sleeve 602, thereby filling the inside of the cuff 3 with air through the inflation tube 601, causing the cuff 3 to expand and continuously pressurize the first pressure sensor 402. Multiple first pressure sensors 402 are connected through the cover plate 403 for synchronous monitoring, and the monitoring structure of the first pressure sensor 402 controls the motor 605 to inflate and deflate. Multiple first pressure sensors 402 are connected through the cover plate 403, forming a single sensor that can monitor the pressure in the patient's larynx over a wider area. Compared to a single sensor, the numerous first pressure sensors 402 can cover a wider area, ensuring that pressure changes throughout the larynx can be accurately captured, greatly improving the comprehensiveness of monitoring and avoiding blind spots. The first pressure sensors 402 are connected to the cover plate 403 to form a whole. When the outer side of the cover plate 403 contacts the patient's larynx, each first pressure sensor 402 can synchronously sense pressure changes and quickly transmit the information. This real-time synchronous feedback mechanism allows the system to react quickly to pressure changes, such as adjusting the motor 605 in time to perform inflation and deflation operations, maintaining stable laryngeal mask pressure, and ensuring patient safety and comfort. Multiple second pressure sensors 501 are distributed and covered with a thin silicone sleeve 502. The average value of the monitoring results of multiple second pressure sensors 501 is used to control the motor 605 by applying pressure to multiple sets of second pressure sensors 501. The distributed arrangement of multiple second pressure sensors 501 can collect pressure data from different locations. Since the pressure distribution in the throat may be uneven, the data from a single second pressure sensor 501 is limited. By taking the average of the monitoring results from multiple second pressure sensors 501, the deviation caused by local pressure fluctuations can be effectively eliminated, making the final data closer to the overall true pressure level of the throat and significantly improving the accuracy of pressure monitoring data. A vision camera 7 is installed on one side of the cuff 3 for real-time observation.
