Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary laryngeal mask, belonging to the field of medical products. Background Technology
[0002] Tracheotomy is an important clinical procedure for relieving airway obstruction and treating critically ill patients. However, the establishment of an artificial airway deprives the upper respiratory tract of its functions of warming, humidifying, filtering, and cleaning inhaled air. Furthermore, patients with artificial airways experience increased airway dehydration, dry mucosa, hardened secretions, and weakened or absent ciliary activity, leading to poor expectoration, thickened sputum, and even crusting. In severe cases, complications such as suffocation may occur. Therefore, adequate airway humidification is extremely important for tracheotomized patients, as it is crucial for maintaining airway patency and preventing respiratory infections.
[0003] The existing tracheostomy requires frequent replacement of the connecting tube to the artificial airway. During the replacement process, secretions between the artificial airway and the connecting tube will fall onto the patient, causing soiling. However, because the patient has an artificial airway, it is inconvenient to change clothes. This can lead to serious problems such as infection, which can affect the patient's recovery. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an auxiliary laryngeal mask.
[0005] An auxiliary laryngeal mask includes a support, on which a detachable anti-fouling pad is provided. The anti-fouling pad has connection holes on both sides. The support includes an upper connecting arm and a lower connecting arm. A mounting seat is provided on the lower connecting arm, and a mounting groove is provided within the mounting seat. A fastening portion, consisting of a plurality of spaced clamping pieces, is located at the center of the mounting groove. A fixing post is provided on the upper connecting arm. An insertion hole for insertion into the fixing post is provided on the fastening portion. A fixing sleeve is rotatably connected to the outside of the fixing post. A fixing groove for threaded connection with the fixing sleeve is provided on the inner wall of the mounting seat. The fixing sleeve is threadedly locked to the fixing groove when the anti-fouling pad is connected to the support by rotation. When the anti-fouling pad is disassembled from the support, the threaded locking connection with the fixing groove is released, allowing the fixing post to exit the insertion hole.
[0006] This technical solution, through the detachable anti-fouling pad on the support, effectively prevents secretions from spilling out during the replacement of artificial airways and external tubing, preventing secretions from dripping onto the patient's body or bed sheets, reducing contamination, improving the cleanliness of the nursing environment, and lowering the risk of cross-infection. The anti-fouling pad is detachable, allowing it to be removed for cleaning or replacement as needed, preventing bacterial growth from prolonged use and improving the hygiene and reusability of the device. The threaded locking structure between the fixing sleeve and the inner wall of the mounting base allows nursing staff to complete the connection or disassembly operation simply by rotating the fixing sleeve, without the need for additional tools, simplifying the replacement process and improving clinical operational efficiency.
[0007] Preferably, the clamping plate has an umbrella-shaped outwardly flared end, and the bottom of the fixing sleeve is provided with a clamping groove for engaging with the end of the clamping plate. The clamping groove fits against the outer wall of the clamping plate, causing the clamping plate to contract and clamp the fixing column.
[0008] This technical solution utilizes an umbrella-shaped, outward-expanding end design for the clamping plate and a clamping groove at the bottom of the fixing sleeve. This allows the clamping plate to radially contract and firmly clamp the fixing post when the fixing sleeve is tightened, forming a reliable locking structure that prevents loosening or detachment at the connection point and improves overall stability. The umbrella-shaped, outward-expanding clamping plate automatically generates a tightening force when engaged with the clamping groove, achieving rapid locking. When the threaded lock is released, the clamping plate returns to its outward-expanding state, facilitating the smooth removal of the fixing post and enabling quick installation and removal of the anti-fouling gasket, thus improving ease of use.
[0009] Furthermore, the number of clamping plates is at least two.
[0010] This technical solution, by setting at least two clamping plates, ensures that the fixed column is subjected to multiple points of uniform force during clamping, avoiding swaying or displacement caused by single-point force, thereby improving the stability and reliability of the connection. The fastening part formed by multiple clamping plates can finely adjust the clamping gap according to the size of the fixed column, adapting to fixed column structures of different diameters, and improving the versatility and assembly accuracy of the device.
[0011] Preferably, the inner wall of the fixing groove is provided with a step, and the fixing sleeve abuts against the end of the step of the fixing groove when the anti-fouling gasket is connected to the bracket.
[0012] This technical solution uses a stepped structure on the inner wall of the fixed groove to create a limiting contact between the fixed sleeve and the end of the step during tightening. This effectively prevents over-tightening by nursing staff, which could lead to stripped threads or damage to parts, thus improving the durability and safety of the connection.
[0013] Preferably, the diameter of the fixing sleeve is larger than the diameter of the connecting hole.
[0014] With this technical solution, since the diameter of the fixing sleeve is larger than the diameter of the connecting hole, the fixing sleeve can cover the edge of the connecting hole after assembly, which structurally restricts the axial movement of the anti-fouling gasket and prevents it from falling off due to shaking or external force during use.
[0015] Preferably, the bracket, upper connecting arm, and lower connecting arm are made of an elastic material.
[0016] This technical solution uses flexible materials to make the brackets and connecting arms, allowing the overall structure to deform appropriately during assembly or disassembly. This facilitates the installation and removal of the anti-fouling gaskets, improving assembly flexibility and convenience.
[0017] Furthermore, the middle part of the bracket is in the shape of an arc-shaped groove.
[0018] This technical solution features a circular groove in the middle of the support, which can naturally fit the patient's neck, reducing gaps and shaking during use and improving overall stability and comfort.
[0019] Preferably, the anti-fouling pad has a mounting hole in the middle for the artificial airway to extend and connect to an external pipe.
[0020] This technical solution allows for the smooth extension of the artificial airway and precise docking with external pipelines by setting an installation hole in the middle of the anti-fouling pad, ensuring the smooth and stable connection of the gas delivery channel.
[0021] The beneficial effects of this invention are as follows: By using injection molding to integrally mold the heel and midsole, the overall structure of the shoe midsole is made more robust, avoiding problems such as breakage and splitting caused by insufficient strength at the bonding or splicing points in traditional split-type manufacturing, thus significantly improving the durability of the shoe midsole. The integrally molded midsole maintains overall stability during wear and will not affect the feel of the foot due to delamination or loosening during use, thereby improving wearing comfort.

[0030] like Figure 1-3 The illustration shows an embodiment of an auxiliary laryngeal mask according to this utility model. It includes a support 1, on which a detachable anti-fouling pad 4 is provided. The anti-fouling pad 4 has connecting holes 41 on both sides. The support 1 includes an upper connecting arm 2 and a lower connecting arm 3. The lower connecting arm 3 has a mounting base 31, and the mounting base 31 has a mounting groove 32. The center of the mounting groove 32 has a fastening part 36 formed by a plurality of spaced clamping pieces 35. The upper connecting arm 2 has a fixing post 21. The part 36 is provided with a plug hole 37 for plugging and connecting with the fixed post 21. The fixed post 21 is rotatably connected to a fixed sleeve 22. The inner wall of the mounting base 31 is provided with a fixed groove 33 for threaded connection with the fixed sleeve 22. The fixed sleeve 22 is threadedly locked to the fixed groove 33 when the anti-fouling pad 4 is connected to the bracket 1 by rotation. When the anti-fouling pad 4 is disassembled from the bracket 1, the fixed sleeve 22 is released from the threaded locking connection with the fixed groove 33, so that the fixed post 21 can be withdrawn from the plug hole 37.
[0031] This technical solution, through the detachable anti-fouling pad 4 on the support 1, effectively prevents secretions from overflowing during the replacement of artificial airways and external tubing, preventing secretions from dripping onto the patient's body or bed sheets, reducing contamination, improving the cleanliness of the nursing environment, and lowering the risk of cross-infection. The anti-fouling pad 4 is detachable, allowing it to be removed for cleaning or replacement as needed, avoiding bacterial growth from prolonged use and improving the hygiene and reusability of the device. The threaded locking structure between the fixing sleeve 22 and the fixing groove 33 on the inner wall of the mounting base 31 allows nursing staff to complete the connection or disassembly operation simply by rotating the fixing sleeve 22, without the need for additional tools, simplifying the replacement process and improving clinical operational efficiency.
[0032] The clamping piece 35 is arranged in an umbrella shape with its end flared outward. The bottom of the fixing sleeve 22 is provided with a clamping groove 23 for fitting into the end of the clamping piece 35. The clamping groove 23 fits against the outer wall of the clamping piece 35, causing the clamping piece 35 to contract and clamp the fixing post 21.
[0033] This technical solution, by designing the end of the clamping piece 35 as an umbrella-shaped outward expansion structure and providing a clamping groove 23 at the bottom of the fixing sleeve 22, allows the clamping piece 35 to radially contract and firmly clamp the fixing post 21 when the fixing sleeve 22 is tightened, thus forming a reliable locking structure, preventing loosening or separation at the connection, and improving overall stability. The umbrella-shaped outward expansion clamping piece 35 automatically generates a tightening force when engaged with the clamping groove 23, achieving rapid locking. When the threaded lock is released, the clamping piece 35 returns to its outward expansion state, facilitating the smooth removal of the fixing post 21, enabling quick installation and removal of the anti-fouling gasket 4, and improving ease of use.
[0034] The number of clamping plates 35 is at least two.
[0035] This technical solution, by setting at least two clamping plates 35, ensures that the fixed column 21 is subjected to multiple points of uniform force during clamping, avoiding wobbling or displacement caused by single-point force, thereby improving the stability and reliability of the connection. The fastening part 36 formed by the multiple clamping plates 35 can finely adjust the clamping gap according to the size of the fixed column 21, adapting to fixed column 21 structures of different diameters, thus improving the versatility and assembly accuracy of the device.
[0036] The inner wall of the fixing groove 33 is provided with a step 34, and the fixing sleeve 22 abuts against the end of the step 34 of the fixing groove 33 when the anti-fouling pad 4 is connected to the bracket 1.
[0037] This technical solution uses a step 34 structure on the inner wall of the fixed groove 33 to create a limiting contact between the fixed sleeve 22 and the end of the step 34 during the tightening process. This effectively prevents the nursing staff from over-tightening the screws during operation, which could lead to thread stripping or damage to parts, and improves the durability and safety of the connection.
[0038] The diameter of the fixing sleeve 22 is larger than the diameter of the connecting hole 41.
[0039] With this technical solution, since the diameter of the fixing sleeve 22 is larger than the diameter of the connecting hole 41, the fixing sleeve 22 can cover the edge of the connecting hole 41 after assembly, which structurally restricts the axial movement of the anti-fouling gasket 4 and prevents it from falling off due to shaking or external force during use.
[0040] The bracket 1, upper connecting arm 2, and lower connecting arm 3 are made of elastic material.
[0041] This technical solution uses a flexible material to make the bracket 1 and connecting arm, so that the overall structure can undergo moderate deformation during assembly or disassembly, which facilitates the installation and disassembly of the anti-fouling pad 4 and improves the flexibility and convenience of assembly.
[0042] The bracket 1 has a circular arc groove in the middle.
[0043] With this technical solution, the middle part of the bracket 1 is designed as an arc-shaped groove, which can naturally fit the patient's neck, reduce gaps and shaking during use, and improve overall stability and comfort.
[0044] The anti-fouling pad 4 has an installation hole 42 in the middle for the artificial airway to extend and connect to the external pipe.
[0045] This technical solution allows the artificial airway to extend smoothly and precisely connect with the external pipeline by setting an installation hole 42 in the middle of the anti-fouling pad 4, ensuring the smooth and stable connection of the gas delivery channel.
[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
[0047] Although the present invention has been described with reference to several specific embodiments, it should be understood that the present invention is not limited to the specific embodiments disclosed. The present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
