AI Technical Summary

Benefits of technology

The present invention addresses the problems of current laryngoscope blade systems. The invention provides a laryngoscope blade that includes a relatively straight main blade portion and a curved moving portion with a straight proximal end, a curved middle portion, and a curved distal tip. The moving portion can be extended outside of the main body portion by a length adjustment means. This design allows for easier handling and flexibility during use.

Problems solved by technology

One of the problems of using the conventional blades is the selection of an appropriate blade for better observation of a Laryngoscope.
As a result the perfect size is estimated based on a patient's age and sex, however this selection is simply an estimate and is not perfectly the needed size for the patient.
None of the blade evaluation methods can determine the exact size for all patients with the similar specifications.
Anatomic differences and emergency condition put the inexperienced doctors in difficult situations.

Embodiment Construction

[0025]Referring to FIG. 1, a top view of one embodiment of a blade 100 of the present invention is illustrated. The blade 100 includes a base 108 that is designed to be coupled to a laryngoscope handle via handle connector portion 131 (shown in FIGS. 2 and 6). Illustrated on the base 108 is a light port 107 designed to direct light from a light source 106 in the handle (not shown) to a light fiber 105 coupled to the blade 100. The blade 100 further includes a relatively straight main blade portion 110 that extends by a length from the base 108. A curved moving portion 103 is illustrated in FIG. 1, wherein a proximal end 104 of the curved moving portion 103 is nestled inside a space 109 of the main blade 110. Distal tip 102 further extends by a length from the moving blade portion 103.

[0026]As illustrated in FIGS. 4 and 7, the proximal end 104 is narrower than the main blade portion 110 and the moving portion 103. That is, the proximal end 104 can easily move and / or slide back and fo...

Abstract

A new Laryngoscopy blade having variable size blade is designed. This blade can supply the necessary length and appropriate view for Laryngoscopy without repeated blade changing.

Description

FIELD OF THE INVENTION[0001]The present invention relates to laryngoscopes, and particularly to an improved blade for a laryngoscope.BACKGROUND OF THE INVENTION[0002]Laryngoscope is a tool for Tracheal intubation in patients who need anesthesia or have breathing difficulties. During CPR and anesthesia in surgery room, the use of a Laryngoscopy is inevitable. All the hospital wards, rescue teams and emergencies have to be equipped with Laryngoscope and know how to use it.[0003]While a laryngoscope may be used to visually examine the larynx, its more important function is to aid in endotracheal intubation. The need for intubation may arise during a controlled situation, such as surgery, or in a crisis situation when the patient is unable to breathe adequately and requires a resuscitation bag or mechanical ventilation. During intubation, a flexible tube is inserted through the nasal or oral cavity, passed through the larynx, and into the trachea for the administration of gases. The lar...
