Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a disposable flexible laryngoscope blade and laryngoscope system. Background Technology

[0002] With the advancement of medical device technology, laryngoscopes have become essential medical equipment in hospitals. Existing laryngoscopes consist of a handle and a lens. The lens is installed on the matching handle, ensuring that the lens is fixed in place. The handle can be reused multiple times. Lenses are available in large, medium, and small sizes. Large lenses are mostly used for adult men, medium lenses for adult women, and small lenses for children and adolescents. When using the laryngoscope, the patient is placed in a supine position with their head tilted back as far as possible. The left hand holds the laryngoscope and inserts it into the oral cavity along the right corner of the mouth. The lens is slowly pushed to the base of the tongue until the epiglottis is seen. The right hand holds the endotracheal tube and inserts it along the groove of the tongue depressor on the laryngoscope until it is inserted into the appropriate position, completing the intubation.

[0003] Difficult airways are common in clinical practice and often threaten patients' lives. With the application of visualization technologies (video laryngoscopes and flexible electronic laryngoscopes), the number of difficult airways in clinical practice has significantly decreased. However, a small number of difficult airways still exist, leading to the development of lever-type difficulty laryngoscopes. These laryngoscopes have a flexible tip, and by adjusting the tip using a lever on the handle, the epiglottis can be lifted, allowing for clear visualization of the glottis. This avoids damage to teeth, tongue, and other soft tissues of the pharynx, and facilitates difficult intubations, such as those involving a high larynx, protruding upper teeth, or posterior displacement of the tongue base. However, these lever-type difficulty laryngoscopes are reusable. If the laryngoscope handle is not thoroughly disinfected after use, there is still a risk of infection, posing risks to both doctors and patients. This application addresses these shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a disposable flexible laryngoscope blade and laryngoscope system. The laryngoscope blade can be used in conjunction with other types of laryngoscopes such as lever-type difficult laryngoscopes. It has an added deformable section for transition and is disposable, which can effectively prevent cross-infection. It solves the problem that lever-type difficult laryngoscopes used for difficult intubation at present have a high risk of infection due to repeated use.

[0005] To address the aforementioned problems, this utility model provides a disposable flexible laryngoscope blade, comprising a fixed part, a deformable part, a movable part, and an internal cavity. The fixed part and the movable part are connected by the deformable part. The internal cavity extends from the fixed part toward the movable part and extends to the position of the movable part. The fixed part includes a laryngoscope connecting end. The deformable part is capable of deformation, allowing the movable part to move within a certain range. The deformable part pulls and limits the movable part, maintaining the integrity of the disposable flexible laryngoscope blade at all times.

[0006] According to one embodiment of the present invention, the deformable part comprises a material having elastic deformation properties.

[0007] According to one embodiment of the present invention, the deformable part is made of silicone rubber, polyurethane or polypropylene or other materials with elastic properties, or a spring can be wrapped with rubber to achieve the effect of elastic deformation.

[0008] According to one embodiment of the present invention, the laryngoscope connecting end includes a limiting hole, a limiting protrusion, a limiting snap-fit ​​structure, etc., for connecting with the laryngoscope handle.

[0009] According to one embodiment of the present invention, the deformable part is provided with one or more segments.

[0010] A laryngoscope system comprising the aforementioned disposable flexible laryngoscope blade and laryngoscope.

[0011] According to one embodiment of the present invention, the laryngoscope is a lever-type difficult laryngoscope. The lever-type difficult laryngoscope includes a limiting part, a laryngoscope blade support, a tongue depressor and a lever. The lever and the tongue depressor are connected by a transmission, generally through a connecting rod. The limiting part is used to connect to the connecting end of the laryngoscope. When the lever is operated to move the tongue depressor, the tongue depressor causes the movable part to move.

[0012] According to one embodiment of the present invention, the laryngoscope is an anesthesia laryngoscope or a video laryngoscope.

[0013] The beneficial effects of this invention are that the deformable part allows the laryngeal blade to bend, so that when used with a difficult laryngoscope, the movable part can move with the depressor, thus solving difficult intubation problems. Since the laryngeal blade is disposable and provides comprehensive protection for the difficult laryngoscope during use, the risk of cross-infection between patients or between patients and doctors is eliminated.

Example 1

[0021] A disposable flexible laryngeal blade, such as Figure 1 It includes a fixed part 11, a deformable part 12, a movable part 13 and an internal cavity, the shape of which can be consistent with that of a traditional laryngeal blade.

[0022] The fixed part 11 and the movable part 13 are connected by a deformable part 12. The internal cavity extends from the fixed part 11 toward the movable part 13 and extends to the position of the movable part 13. The fixed part 11 has an opening at one end for the insertion of a laryngoscope. The internal cavity preferably extends to the root position of the movable part 13 to avoid affecting the bending performance of the movable part 13. The fixed part 11 includes a laryngoscope connecting end, which includes a limiting hole 111 for connecting with the laryngoscope handle.

[0023] The deformable part 12 can deform, allowing the movable part 13 to move within a certain range, such as... Figure 2 It can bend and move from the initial position 131 of the movable part to the upward position 132 of the movable part. The deformable part 12 pulls and limits the movable part 13, and always maintains the integrity of the disposable flexible laryngoscope blade.

[0024] The deformable part 12 is made of a material with elastic deformation properties, preferably silicone rubber, polyurethane or polypropylene.
