Description

A visual laryngeal mask with an anesthetic spray device Technical Field

[0001] This invention relates to the field of clinical anesthesia and airway management equipment, and in particular to a visual laryngeal mask with an anesthetic injection device. Background Technology

[0002] Video laryngeal masks are key devices in clinical anesthesia and airway management, combining airway establishment, ventilation support, and visual positioning functions. They are widely used in surgical anesthesia, emergency resuscitation, and other scenarios. To improve anesthesia comfort and ease of operation, some video laryngeal masks integrate anesthetic injection devices, which precisely deliver anesthetic to the patient's throat through an internal tube to achieve local anesthesia or assist general anesthesia.

[0003] Existing video laryngeal masks with anesthetic spraying functions pose significant safety hazards: their anesthetic delivery tubing is mostly of a straight-through structure, lacking an effective backflow prevention mechanism. When anesthesia delivery stops or the patient's position changes, mucus, secretions, and small amounts of refluxed material in the throat can easily be aspirated back into the anesthesia machine through the anesthetic tubing. This backflow not only contaminates the anesthesia machine's tubing and internal components, increasing the difficulty of equipment cleaning and disinfection and maintenance costs, but may also lead to anesthetic contamination and tubing blockage, affecting the accuracy of subsequent anesthetic administration. More seriously, pathogens in the refluxed material may cause cross-infection, threatening the health and safety of patients and medical staff.

[0004] Therefore, it is necessary to provide a visual laryngeal mask with an anesthetic injection device to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] First Embodiment

[0034] Please refer to Figures 1, 2, 3, and 4. Figure 1 is a schematic diagram of the structure of a first embodiment of a visual laryngeal mask with an anesthetic spraying device provided by the present invention; Figure 2 is a schematic diagram of the structure of the anesthesia delivery assembly shown in Figure 1; Figure 3 is a schematic diagram of the cross-sectional structure of the unidirectional assembly shown in Figure 2; and Figure 4 is an enlarged schematic diagram of part A shown in Figure 1.

[0035] A visual laryngeal mask with an anesthetic injection device includes: a body 1;

[0036] Mainstream channel 2, which is fixedly installed on one side of the main body 1;

[0037] An inflation component 3 is disposed on the other side of the main body 1;

[0038] Anesthesia delivery assembly 4 is disposed on the side of the main channel 2. The anesthesia delivery assembly 4 includes a first pipe 41, a one-way component 42 is fixedly installed at one end of the first pipe 41, and a second pipe 43 is fixedly installed at one end of the one-way component 42.

[0039] Support component 5, which is disposed on the outer side of the main channel 2;

[0040] Spraying component 6 is disposed on one side of the main body 1.

[0041] The main body 1 provides the installation base for each functional component, while the main channel 2 is used to establish a ventilation airway to ensure the patient's breathing.

[0042] The inflation assembly 3 includes an airbag 31, which is fixedly installed on one side of the main body 1, and an inflation tube 32 is fixedly installed on the side of the airbag 31.

[0043] The inflation tube 32 connects to the inflation device, inflating the airbag 31 to make it expand and fit the pharyngeal tissue to achieve airway sealing; the airbag 31 is made of flexible biocompatible material to avoid damaging the pharyngeal mucosa and improve patient comfort.

[0044] The spraying assembly 6 includes a delivery pipe 61, which is fixedly installed on the inner side of the airbag 31. A plurality of nozzles 62 are fixedly installed on one side of the delivery pipe 61, and the other end of the delivery pipe 61 and the first pipe 41 are fixedly installed.

[0045] The anesthetic enters the delivery tube 61 through the second pipe 43, the one-way component 42, and the first pipe 41, and is evenly sprayed to the target area of ​​the throat through multiple nozzles 62 to ensure comprehensive anesthetic coverage; the nozzles 62 adopt a micro-spray design to avoid local irritation caused by concentrated spraying of anesthetic.

[0046] The unidirectional component 42 includes a housing 421, a mounting base 422 is fixedly installed on the inner side of the housing 421, a backflow prevention component 423 is provided on the inner side of the mounting base 422, and a filter component 424 is provided at the bottom of the backflow prevention component 423.

[0047] The anti-reverse assembly 423 includes a piston plate 4231, a sealing sleeve 4232 fixedly installed on the outer side of the piston plate 4231, the outer side of the sealing sleeve 4232 fitting against the inner side of the mounting base 422, a connecting rod 4233 fixedly installed on the bottom of the piston plate 4231, a spring 4234 sleeved on the outer side of the connecting rod 4233, a connecting plate 4236 fixedly installed on the bottom of the connecting rod 4233, and scrapers 4235 fixedly installed at both ends of the connecting plate 4236.

[0048] The filter assembly 424 includes a cylindrical body 4241, the bottom of which is fixedly installed on the bottom of the inner side of the outer shell 421. Side grooves 4243 are provided on both sides of the cylindrical body 4241, and filter screens 4242 are fixedly installed on the inner sides of the two side grooves 4243. The outer side of the scraper 4235 is attached to the inner side of the two filter screens 4242.

[0049] The piston plate 4231 of the anti-reverse assembly 423 moves downward under the pressure of anesthetic delivery to open the channel; when delivery stops, the spring 4234 returns to its original position and pushes the piston plate 4231 to fit against the mounting base 422, and the sealing sleeve 4232 enhances the sealing performance, blocks the backflow channel, and prevents the backflow of secretions.

[0050] The filter screen 4242 of the filter assembly 424 intercepts impurities and possible secretion residues in the anesthetic, preventing pipeline blockage; when the piston plate 4231 moves up and down, it drives the scraper 4235 to scrape the surface of the filter screen 4242 through the connecting rod 4233, realizing automatic cleaning and preventing the filter screen 4242 from clogging.

[0051] The working principle of the visual laryngeal mask with an anesthetic injection device provided by the present invention is as follows:

[0052] In use, the laryngeal mask body 1 is placed into the patient's throat, and the air bag 31 is inflated through the inflation tube 32, sealing the airway. An anesthetic supply device is connected through the second pipe 43. The anesthetic pressure pushes the piston plate 4231 downwards, compressing the spring 4234 and opening the passage. After passing through the filter 4242, the anesthetic is sprayed from the nozzle 62 through the first pipe 41 and the delivery pipe 61, evenly covering the throat.

[0053] When the delivery of anesthetic is stopped, the spring 4234 returns to its original position, pushing the piston plate 4231 to fit tightly against the mounting base 422. The sealing sleeve 4232 blocks the backflow channel, preventing pharyngeal secretions from flowing back into the anesthesia device. During the movement of the piston plate 4231, the scraper 4235 simultaneously scrapes the filter screen 4242 to remove residual impurities on the surface and keep the filter screen 4242 unobstructed.

[0054] Compared with related technologies, the visual laryngeal mask with an anesthetic injection device provided by the present invention has the following beneficial effects:

[0055] Through the coordinated structure of the main body 1, anesthesia delivery component 4, one-way component 42, anti-reverse component 423, and filter component 424, when in use, the piston plate 4231, sealing sleeve 4232, and spring 4234 of the anti-reverse component 423 cooperate to open the channel when the anesthetic is delivered under pressure. After delivery stops, the spring 4234 resets and pushes the piston plate 4231 to seal, blocking the backflow path and preventing the backflow of throat secretions to contaminate the anesthesia equipment, reducing the risk of cross-infection. This solves the problem of existing devices lacking an anti-backflow mechanism and being prone to secretion backflow contamination.

[0056] Second Embodiment

[0057] Referring to Figure 5, based on the first embodiment of this application which provides a visual laryngeal mask with an anesthetic spraying device, the second embodiment of this application proposes another visual laryngeal mask with an anesthetic spraying device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0058] Specifically, the difference in the second embodiment of this application is that the visual laryngeal mask with an anesthetic spray device is that the support assembly 5 includes a support plate 51, the support plate 51 has an installation groove 52 inside, the installation groove 52 is installed on the outer side of the main channel 2, and the support plate 51 has a tooth groove 53 on both the front and back.

[0059] Both ends of the support plate 51 are provided with snap-fit ​​grooves 54, and the second pipe 43 and the inflation pipe 32 are snapped into the inner side of the snap-fit ​​grooves 54.

[0060] The support plate 51 is fixed to the main channel 2 via the mounting groove 52. The alveolar 53 is adapted to the patient's teeth to enhance the stability of the laryngeal mask and prevent displacement. The snap-fit ​​groove 54 houses and fixes the second pipe 43 and the inflation tube 32 to avoid pipe entanglement or pressure and ensure smooth delivery of gas and anesthetic.

[0061] The working principle of the visual laryngeal mask with an anesthetic injection device provided by the present invention is as follows:

[0062] When worn, the patient's teeth are embedded in the alveolar 53, which restricts the movement of the support plate 51 and thus fixes the overall position of the laryngeal mask. The second tube 43 and the inflation tube 32 are inserted into the locking groove 54 to keep the tubes neat and avoid twisting or pressure during operation. This ensures that the delivery of anesthetic and the inflation of the cuff are not affected and also prevents the patient from biting directly on the main channel 2.

[0063] Compared with related technologies, the visual laryngeal mask with an anesthetic injection device provided by the present invention has the following beneficial effects:

[0064] The support plate 51, mounting groove 52, alveolar 53, snap-fit ​​groove 54, and other structures cooperate with the main channel 2, the second pipe 43, and the inflation tube 32. The alveolar 53 is adapted to the teeth to fix the position of the laryngeal mask and prevent the laryngeal mask from shifting when the body position changes. The snap-fit ​​groove 54 neatly fixes the pipeline, prevents twisting and pressure, and ensures stable anesthesia delivery.

[0065] Third Embodiment

[0066] Referring to Figures 6 and 7, based on the visual laryngeal mask with an anesthetic spray device provided in the first embodiment of this application, the third embodiment of this application proposes another visual laryngeal mask with an anesthetic spray device. The third embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the separate implementation of the first embodiment.

[0067] Specifically, the difference in the third embodiment of this application regarding the visual laryngeal mask with an anesthetic spray device is that a camera 7 is fixedly installed on the other side of the main body 1, and a cleaning component 8 is also provided on the other side of the main body 1.

[0068] The cleaning component 8 includes two side plates 81. Each of the two side plates 81 has a movable groove 82 on one side facing each other. A scraper 84 is slidably connected to the inner side of the movable groove 82. The scraper 84 is attached to one side of the camera 7. Elastic ropes 83 are fixedly installed at both ends of one side of the scraper 82. One end of each of the two elastic ropes 83 is fixedly installed on the inner side of the movable groove 82. A pull rope 85 is fixedly installed on the other side of the scraper 82.

[0069] Camera 7 enables visual positioning of the throat, facilitating precise placement of the laryngeal mask and observation of the anesthesia effect by medical staff; cleaning component 8 can quickly clean secretions or fog from the surface of camera 7, ensuring a clear field of view.

[0070] The working principle of the visual laryngeal mask with an anesthetic injection device provided by the present invention is as follows:

[0071] During visualization positioning, camera 7 transmits images of the throat. If the surface is contaminated with secretions or fogged up, affecting the field of vision, pull the rope 85 to drive the scraper 84 to slide along the moving groove 82, scraping the surface of camera 7 to remove the dirt; release the rope 85, and the elastic rope 83 resets, driving the scraper 84 back to the initial position, without affecting subsequent observation.

[0072] Compared with related technologies, the visual laryngeal mask with an anesthetic injection device provided by the present invention has the following beneficial effects:

[0073] By working together with components such as the cleaning unit 8 and the camera 7, pulling the pull rope 85 can cause the scraper 84 to slide along the moving groove 82, quickly scraping away secretions or fog on the surface of the camera 7; after releasing, the elastic rope 83 causes the scraper 84 to return to its original position, ensuring a clear field of vision for the camera 7, making it easier for medical staff to accurately place the laryngeal mask and reducing displacement of the laryngeal mask due to positioning deviation.

[0074] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
