Description

 Throat mirror for a rotatable and flipping display  

The present invention relates to a laryngoscope, and more particularly to a laryngoscope that can be rotated and flipped.

Press, when the emergency patient or general anesthesia of the patient, the medical staff needs to put the plastic tracheal tube into the patient's trachea and provide oxygen to maintain the patient's breathing.

About 80% of patients can be opened into the endotracheal tube by a slightly experienced physician using a general laryngoscope to open the patient's mouth. However, about 20% of patients have different degrees of difficulty in looking directly at the tracheal opening because of the shorter jaw or shorter neck. Therefore, some people have designed to mount the photographic lens on the front end of the laryngoscope. The screen uses a large screen to view images captured by the laryngoscope. However, the large screen is cumbersome and difficult to carry, and when the novice uses the endotracheal tube to operate the throat mirror, it is necessary to look at the large screen and place the endotracheal tube into the patient's mouth, thus increasing the difficulty of installing the endotracheal tube. Therefore, there has been developed a throat mirror that is designed to be integrally formed with a lens at the front end of the platen, a light source beside the lens, and a smaller screen disposed on the upper side of the grip, which is easy to operate. However, because the angle of view of the lens limits the viewing angle of the screen adjustment, if the viewing angle is low or high, the screen image cannot be clearly seen, which will again cause the inconvenience of the operation of the throat mirror.

In addition, when you are rescued from drowning, heavy blows, or other factors that cause you to fall into an unconscious state, you need to keep the patient's respiratory tract clear to ensure the patient's normal breathing. However, if the patient has vomiting symptoms, or there may be foreign body obstruction of the respiratory tract, the rescuer must first open the patient's mouth and carefully observe the patient's throat to confirm whether there is any obstruction. If so, Other means should be applied as soon as possible to allow foreign matter to be expelled to prevent the patient's respiratory tract from being blocked by vomit or foreign matter and unable to circulate air.

In general, when the rescuer wants to open the mouth of the unconscious patient to observe the throat of the patient, the tongue root of the unconscious patient tends to block the throat due to bulging or swinging, which causes difficulty for the rescuer to observe; Moreover, the method relies on the visual acuity of the rescuer. If the rescuer has poor eyesight, the throat will be difficult to observe deeper, and there are often dead corners inside the throat, which has certain difficulties in visual observation.
