Description

Technical Field

[0001] This utility model relates to the field of bionic device technology, specifically a bionic anatomical curved laryngeal mask body. Background Technology

[0002] The laryngeal mask airway (LMA) is a medical device used for airway management and plays an important role in clinical anesthesia, emergency resuscitation and other scenarios. As a core medical device for airway management, the LMA has an irreplaceable role in clinical anesthesia, emergency resuscitation and intensive care. It maintains patient ventilation by establishing an artificial airway and is a key link in ensuring respiratory safety.

[0003] Traditional laryngeal mask designs have certain shortcomings in conforming to the anatomical structure of the human throat, which may lead to poor sealing and airway compression damage, affecting the safety and effectiveness of airway management. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a biomimetic anatomical curved laryngeal mask. By setting an air bladder ring, air bladder bulb, inflation bulb, and tube outside the larynx, pressing the air bladder bulb inflates the air bladder ring through the tube. This allows for flexible adjustment of the larynx's expansion degree according to the patient's pharyngeal physiological characteristics and individual differences, adapting to different anatomical structures, forming a tight and stable fit, reducing air leakage, ensuring ventilation effectiveness, lowering the risk of anesthetic gas leakage and airway pressure instability, and improving the reliability and safety of airway management. Furthermore, by setting a positioning ring, a locking hole, and a rubber disc outside the larynx, the positioning rod, after entering the hole, compresses the rubber disc, causing it to deform and pass through the locking hole, tightly fitting the outer surface of the positioning ring, ensuring precise component positioning and laying the foundation for stable operation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a biomimetic anatomical curved laryngeal mask body, comprising,

[0008] A laryngeal mask assembly, the laryngeal mask assembly including a laryngeal tube;

[0009] A sealing component, comprising an airbag ring, an airbag ball, an inflatable ball, a tube body, and a support ring, wherein the support ring is bonded to both ends of the outer surface of the trachea, the airbag ring is embedded in the outer surface of the trachea, the airbag ball is disposed on the outer surface of the airbag ring, the tube body is fixed to one end of the outer surface of the airbag ring, and the inflatable ball is fixed to the outer surface of the tube body.

[0010] Preferably, the airbag balls are evenly distributed, and the support ring surrounds the top and bottom of the airbag ring.

[0015] (III) Beneficial Effects

[0016] This invention provides a biomimetic anatomical curved laryngeal mask. It has the following beneficial effects:

[0017] (1) This biomimetic anatomical curved laryngeal mask has an air bladder ring, an air bladder bulb, an inflatable bulb, and a tube on the outside of the larynx. The operator only needs to press the air bladder bulb, and the gas will be quickly transferred to the air bladder ring through the tube. It can flexibly adjust the degree of expansion of the larynx according to the actual physiological characteristics and individual differences of the patient's pharynx and larynx. It can better adapt to the unique anatomical structure of different patients' pharynx and larynx, forming a tight and stable fit, and minimizing the occurrence of air leakage. This not only ensures the ventilation effect during airway management, but also effectively reduces the risk of anesthetic gas leakage and airway pressure instability caused by air leakage, and significantly improves the reliability and safety of airway management.

[0018] (2) The biomimetic anatomical curved laryngeal mask body has a positioning ring, a snap-fit ​​hole and a rubber disc on the outside of the laryngeal tube. When the positioning rod accurately enters the hole, it will exert just the right amount of pressure on the rubber disc, causing the rubber disc to deform and pass smoothly through the snap-fit ​​hole. Finally, the rubber disc tightly blocks the outer surface of the positioning ring. This process ensures that the positions of each component are accurate and lays a solid foundation for the stable operation of the entire system. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a biomimetic anatomical curved laryngeal mask body, comprising,

[0026] A laryngeal mask assembly, the laryngeal mask assembly including a laryngeal tube 1;

[0027] The sealing component includes an airbag ring 4, an airbag ball 5, an inflatable ball 6, a tube body 7, and a support ring 9. The support ring 9 is bonded to both ends of the outer surface of the trachea 1. The airbag ring 4 is embedded in the outer surface of the trachea 1. The airbag ball 5 is disposed on the outer surface of the airbag ring 4. The tube body 7 is fixed to one end of the outer surface of the airbag ring 4. The inflatable ball 6 is fixed to the outer surface of the tube body 7.

[0028] The operator only needs to press the balloon 5, and the gas will be quickly transferred to the inside of the balloon ring 4 through the tube 7. The expansion degree of the larynx 1 can be flexibly adjusted according to the actual physiological characteristics and individual differences of the patient's throat. It can better adapt to the unique anatomical structure of different patients' throats, forming a tight and stable fit, and minimizing the occurrence of air leakage. This not only ensures the ventilation effect during airway management, but also effectively reduces the risk of anesthetic gas leakage and airway pressure instability caused by air leakage, significantly improving the reliability and safety of airway management.

[0029] The airbag balls 5 are evenly distributed, and the support rings 9 surround the top and bottom of the airbag rings 4. After the airbag rings 4 are embedded in the outside of the larynx 1, the support rings 9 at one end will be embedded in the outside of the larynx 1, so that the support rings 9 surround the top and bottom of the airbag rings 4 for limiting.

[0030] The support ring 9 has a positioning hole 10 inside. The top and bottom of the airbag ring 4 are fixed with positioning rods 8. The positioning rods 8 are inserted into the positioning hole 10 to reinforce the airbag ring 4 after installation.

[0031] The laryngeal mask assembly also includes a laryngeal mask shell 2 and a connecting port 3. The laryngeal mask shell 2 is fixed to the bottom of the laryngeal tube 1, and the connecting port 3 is fixed to the top of the laryngeal tube 1.

[0032] It also includes a reinforcing component, which includes a positioning ring 12 and a snap-fit ​​hole 13. The positioning ring 12 is embedded in the outer surface of the throat tube 1, and the snap-fit ​​hole 13 is opened inside the positioning ring 12. The positioning rod 8 is inserted into the snap-fit ​​hole 13.

[0033] When the positioning rod 8 accurately enters the hole, it will exert just the right amount of pressure on the rubber disc 11, causing the rubber disc 11 to deform and pass smoothly through the snap-fit ​​hole 13. Finally, the rubber disc 11 is tightly blocked on the outer surface of the positioning ring 12. This process ensures that the positions of each component are accurate, laying a solid foundation for the stable operation of the entire system.

[0034] A rubber disc 11 is bonded to the outside of the positioning rod 8, and the rubber disc 11 blocks the outer surface of the positioning ring 12.

[0035] The working principle of this biomimetic anatomical curved laryngeal mask is as follows: First, the airbag ring 4 is embedded in the outside of the larynx 1, and the support ring 9 at one end is simultaneously embedded in the outside of the larynx 1, so that the support ring 9 surrounds the top and bottom of the airbag ring 4. At the same time, the positioning rod 8 is inserted into the positioning hole 10. When the positioning rod 8 accurately enters the hole, it will exert just the right amount of pressure on the rubber disc 11, causing the rubber disc 11 to deform and smoothly pass through the snap-fit ​​hole 13. Finally, the rubber disc 11 is tightly blocked on the outer surface of the positioning ring 12. This process ensures that the positions of each component are accurate, which is crucial for the stability of the entire system. This system lays a solid foundation for stable operation. Operators only need to press the balloon 5, and the gas will be quickly transferred to the inside of the balloon ring 4 through the tube 7. It can flexibly adjust the expansion degree of the larynx 1 according to the actual physiological characteristics and individual differences of the patient's throat. It can better adapt to the unique anatomical structure of different patients' throats, forming a tight and stable fit, and minimizing the occurrence of air leakage. This not only ensures the ventilation effect during airway management, but also effectively reduces the risk of anesthetic gas leakage and airway pressure instability caused by air leakage, significantly improving the reliability and safety of airway management.
