Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laryngoscope blades, in particular to a novel visual laryngoscope blade. Background Art
[0002] One of the most important tasks in clinical anesthesia is airway management. Ensuring the patient's breathing is the prerequisite for the success of every operation. The first and most important step in airway management is to establish an artificial airway, and tracheal intubation is the most reliable and most commonly used method. Failure of tracheal intubation or failure of airway control will lead to complications in patients, and even endanger the patient's life in severe cases. Only when the airway is well controlled can the patient's oxygen supply be guaranteed, thereby ensuring the most fundamental safety of the entire perioperative period. The success of tracheal intubation depends entirely on the doctor's good skills and reliable intubation auxiliary tools.
[0003] Video laryngoscope, as a new auxiliary tool for endotracheal intubation, has the advantages of complete glottis exposure, minimal airway damage, and short operation time. Especially in the case of endotracheal intubation of difficult airways, it can effectively reduce the difficulty of operation and highlight its advantages.
[0004] The portable video laryngoscope system consists of a disposable laryngoscope blade, a handle, and a display screen integrated on the handle. Usually, a tracheal tube clamp or a tracheal tube buckle is provided on the disposable laryngoscope blade to guide and limit the tracheal tube so that it can be accurately inserted into the patient's trachea. However, when separating after the insertion is completed, the tracheal tube needs to be pulled to separate it from the tracheal tube clamp or the tracheal tube buckle. The tracheal tube moving in the patient's trachea can easily cause harm to the patient, so a new type of video laryngoscope blade is needed to solve the above problem. Utility Model Content

Specific implementation mode
[0017] Embodiment 1
[0018] As Figures 1 to 4 shown, the present utility model discloses a new type of visible laryngoscope blade. The technical solution adopted is that it includes a main body 1 of the laryngoscope blade and a guiding wing plate 2. A connection structure 101 is arranged at the upper end of the main body 1 of the laryngoscope blade. The connection structure 101 is a snap or plug-in structure. Through the connection structure 101 of the snap or plug-in structure, the main body 1 of the laryngoscope blade can be fixedly connected with the handle of the visible laryngoscope. A viewing window 103 is arranged at the lower end of the main body 1 of the laryngoscope blade. The guiding wing plate 2 is arranged at the inner edge of the front side of the main body 1 of the laryngoscope blade. A tongue depressor 102 is arranged at the lower end of the main body 1 of the laryngoscope blade, and the tongue depressor 102 is connected with the guiding wing plate 2. The connection part between the guiding wing plate 2 and the tongue depressor 102 is an arc-shaped structure. Through the arc-shaped connection part between the guiding wing plate 2 and the tongue depressor 102, it can prevent scratching the patient. An installation groove 104 with the same curvature as the guiding wing plate 2 is arranged at the outer edge of the front side of the main body 1 of the laryngoscope blade. A limiting soft strip 3 is arranged in the installation groove 104. The rear end of the limiting soft strip 3 is inserted into the installation groove 104. A limiting chamber is formed between the limiting soft strip 3 and the guiding wing plate 2, and the upper and lower ends of the limiting chamber are open. The lower end of the limiting soft strip 3 is limited by the lower end of the installation groove 104. By limiting the lower end of the limiting soft strip 3, it can effectively prevent the limiting soft strip 3 from detaching from the lower end of the installation groove 104 and then inserting into the patient's body. Retaining teeth 301 are evenly arranged at the inner end of the front side of the limiting soft strip 3. Through the retaining teeth 301, it can prevent the tracheal catheter 4 from detaching from the side opening of the limiting chamber. A pinch block 302 is arranged at the upper end of the limiting soft strip 3. Through the pinch block 302, it is convenient to control the separation of the limiting soft strip 3 from the installation groove 104. The tracheal catheter 4 is guided through the limiting chamber between the limiting soft strip 3 and the guiding wing plate 2. Through the insertion connection mode of the installation groove 104 and the limiting soft strip 3, the limiting chamber can be opened, so as to facilitate the separation from the tracheal catheter 4 inserted into the patient's body.
[0019] Working principle of the present utility model: Insert the lens of the video laryngoscope into the main body 1 of the laryngoscope blade, connect it with the handle of the video laryngoscope using the connecting structure 101, insert the main body 1 of the laryngoscope blade into the patient's oral cavity, and use the tongue depressor 102 to press the patient's tongue. When the glottis image appears on the display screen of the video laryngoscope, adjust this device to orient the limiting cavity formed by the limiting soft strip 3 and the guiding wing plate 2 towards the glottis. Then insert the tracheal catheter 4 from the upper end of the limiting cavity so that it can correctly enter the glottis. After the tracheal catheter 4 is installed, pinch the pinch block 302 and pull it upward or laterally to separate the limiting soft strip 3 from the installation groove 104. Then take out the limiting soft strip 3 from the patient's oral cavity and take out the main body 1 of the laryngoscope blade obliquely to avoid touching the tracheal catheter 4 and causing it to be displaced.
