CONVENTIONAL LARYNGOSCOPE VALVA CURVA

• The conventional laryngoscope is a simple medical instrument primarily used to examine the glottis and vocal cords.

• The inventor of the first laryngoscope was the opera singing teacher Manuel García.

• Its function is to observe the interior of the larynx and to have a better vision than the one already mentioned through images, thus they can give a diagnosis of any symptomatology in the speech therapy device.

• The device is made up of two parts:

• A handle to handle the instrument. In the case of fiber optic laryngoscopes or with another type of light source, the handle contains the batteries that power the bulb or light source.

• A blade that serves to separate the tongue and the epiglottis. At the end of the blade there is usually a light source (a small bulb or a source of fiber optic light source on the handle). The blade can be reusable, in which case it must be sterilized after each use, or disposable.

LARYNGOSCOPES

The laryngoscope is a simple medical instrument primarily used to examine the glottis and vocal cords.

The device consists of two parts:

• A blade that serves to separate the tongue and the epiglottis. At the end of the blade there is usually a light source (a small bulb or a source of fiber optic light source on the handle). The blade can be reusable, in which case it must be sterilized after each use, or disposable.

• A handle to handle the instrument. In the case of fiber optic laryngoscopes or with another type of light source, the handle contains the batteries that power the bulb or light source.

The development and use of the laryngoscope in medical practice is largely due to the German physician Johann Czermak,

The handle is made to hold the laryngoscope and contains the batteries

The leaflet is the part of the laryngoscope that is inserted into the patient's oropharynx. It has a light source at the end of the blade. The valve consists of three parts: the spatula, the rim, and the tip. The spatula is used to manipulate soft tissues, the longitudinal axis of the spatula can be straight or curved. The rim is the portion of the valve that protrudes from the edge of the spatula and that serves to reject the tissues that are in the way, for example, the tongue.

The most frequently used type of leaflet is the Macintosh type curve. They are numbered from 1 to 4 from least to greatest. According to some authors, according to some authors, up to 6 months and according to others, up to three months, a straight leaflet should be used, since this is adequate due to the anatomical characteristics of the airway in it.
