[0001] The present invention belongs to the technical field of laryngeal mask auxiliary devices, and particularly relates to an auxiliary device for placing a laryngeal mask. Background Technique

[0002] The laryngeal mask was successfully developed and used clinically in the mid-1980s and introduced into China in the 1990s. At present, great progress has been made in the use of laryngeal masks, and the application scope is becoming wider and wider. The laryngeal mask is an effective means for establishing a safe airway during general anesthesia surgery; the first and second generations of laryngeal masks have many advantages: 1. Simple to use and can quickly establish an artificial airway; 2. High placement success rate, the success rate of untrained medical staff is 87%, and the total success rate is 99.81%; 3. Reliable ventilation; 4. Avoid damage to the throat and tracheal mucosa; 5. Little stimulation and little cardiovascular reaction; 6. Can be used for first aid.

[0003] When using a laryngeal mask, it is generally held directly with fingers and sent into the patient's mouth; although this method is simple, it still causes some pain to the patient during placement, and the patient's mouth may be damaged during insertion. Sometimes, various vomiting reactions may occur inside the patient's mouth. When this happens, it is very likely that the laryngeal mask will come out, making it difficult to treat the patient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution: an auxiliary device for placing a laryngeal mask, including an oral cavity tube 1. A through groove 2 is opened inside the oral cavity tube 1. A fixed tube 3 is fixedly installed at the bottom of the inner wall of the through groove 2. A moving rod 4 is movably installed inside the fixed tube 3. A moving thread 5 is spirally and fixedly sleeved outside the moving rod 4. One end of the moving thread 5 is fixedly installed with a rotating card slot 8. A rotating card block 9 is movably installed inside the rotating card slot 8. One end of the rotating card block 9 away from the rotating card slot 8 is fixedly installed with a pushing rod 10. One end of the pushing rod 10 away from the rotating card block 9 is fixedly installed with a U-shaped pushing member 11.

[0020] In this implementation scheme, the through groove 2 opened inside the oral cavity tube 1 can facilitate the placement of the pipeline of the laryngeal mask therein. By installing the U-shaped pushing member 11, the top end of the laryngeal mask can be held. Rotating the held rotating block 7 can drive the rotating rod 6 to rotate. By the rotating rod 6, the moving rod 4 is driven. Through the moving rod 4 and the fixed tube 3, the rotating card block 9 and the rotating card slot 8 can be driven to move forward. Then, by the pushing rod 10, the U-shaped pushing member 11 is pushed so that the top end of the laryngeal mask can move into the throat. During the treatment process, through the mutual support of the internal structures of the fixed tube 3 and the moving rod 4, it can effectively prevent the laryngeal mask from being spit out due to physical discomfort, thereby greatly improving the utilization efficiency of the laryngeal mask.

[0021] Specifically, an inner ring thread adapted to the specification and size of the moving thread 5 is opened inside the fixed tube 3. The specification and size of the rotating card slot 8 and the rotating card block 9 are adapted to each other.

[0022] In this embodiment, through the inner ring thread opened inside the fixed tube 3 that is adapted to the specification and size of the moving thread 5, it can facilitate the forward and backward movement of the moving rod 4. And through the rotating card slot 8 and the rotating card block 9 with adapted specification and size, it can effectively prevent the pushing rod 10 from rotating along with the moving rod 4.

[0023] Specifically, a rotating rod 6 is fixedly installed at one end of the moving rod 4 away from the rotating card slot 8. A rotating block 7 is fixedly installed at one end of the rotating rod 6 away from the moving rod 4.

[0024] In this embodiment, by installing the rotating rod 6 and the rotating block 7, it is convenient for medical staff to rotate, thereby driving the moving rod 4 to rotate.

[0025] Specifically, an inlet throat tube 12 is fixedly installed on the front of the oral cavity tube 1. A limiting tube 13 is fixedly installed at the bottom of the inner wall of the inlet throat tube 12. A protruding corner 14 is fixedly installed on one side of the oral cavity tube 1 away from the inlet throat tube 12.

[0026] In this embodiment, the installed inlet throat tube 12 facilitates the entry of the laryngeal mask from the oral cavity into the throat. The installed limiting tube 13 can effectively limit the position of the push rod 10, thereby facilitating the assistance of the laryngeal mask. The installed protruding corner 14 can adapt to the lips of most patients.

[0027] Specifically, the through groove 2 penetrates through the inlet throat tube 12 and the protruding corner 14 respectively in the front and back. One end of the push rod 10 away from the rotary locking block 9 penetrates through the limiting tube 13 inside the inlet throat tube 12 and extends to the outside of the inlet throat tube 12. One end of the rotary rod 6 away from the moving rod 4 penetrates through the protruding corner 14 and extends into the inside of the protruding corner 14.

[0028] In this embodiment, the rotary rod 6 and the push rod 10 that penetrate through and extend outside respectively in the front and back facilitate the use by medical staff.

[0029] Specifically, an upper tooth bite block 15 is fixedly installed on the top of the oral cavity tube 1. An upper tooth bite groove 16 is formed on the top of the upper tooth bite block 15. A lower tooth bite block 17 is fixedly installed on the bottom of the oral cavity tube 1. A lower tooth bite groove 18 is formed on the bottom of the lower tooth bite block 17.

[0030] In this embodiment, the installed upper tooth bite block 15 and lower tooth bite block 17 can effectively prevent the patient's teeth from damaging the pipeline and the oral cavity tube 1 during the use of the laryngeal mask on the patient. The installed tooth bite grooves can adapt to the teeth of most people.

[0031] Specifically, the upper tooth bite block 15 and the lower tooth bite block 17 have the same specifications and dimensions. The upper tooth bite block 15 and the lower tooth bite block 17 are correspondingly positioned. The opening positions of the upper tooth bite groove 16 and the lower tooth bite groove 18 are opposite.

[0032] In this embodiment, the correspondingly positioned and dimensionally adapted upper tooth bite block 15 and lower tooth bite block 17 can adapt to the tooth shapes of most people.

[0033] Working principle and usage process of the present invention: After moving the device to the designated position, insert the pipeline of the laryngeal mask into the oral cavity tube 1 from the laryngeal inlet tube 12. The U-shaped pusher 11 can hold the top of the laryngeal mask. Rotating the rotating block 7 that is held can drive the rotating rod 6 to rotate. The rotating rod 6 drives the moving rod 4, and the moving rod 4 and the fixed tube 3 can drive the rotating block 9 and the rotating slot 8 to move forward. By pushing the U-shaped pusher 11 with the push rod 10, the top of the laryngeal mask can move into the throat. During the treatment process, through the mutual support of the internal structures of the fixed tube 3 and the moving rod 4, it can effectively prevent the laryngeal mask from being spit out due to physical discomfort, thereby greatly improving the utilization efficiency of the laryngeal mask.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
