Abstract
Abstract A fiberoptic intubation stylet is an endotracheal intubation aid for use with a fiberoptic scope to facilitate difficult endotracheal intubations particularly when a direct line of sight is not available due to patient's anatomy or pathology. The fiberoptic intubation stylet comprises a pre-sterilized soft transparent plastic holding sheath with a longitudinally built-in malleable metal stylet. The tubular holding sheath provides a neat and secure contact of the fiberoptic scope so that the stylet can be held in position. The malleable stylet makes the fiber optic scope as firm and able to be curled into a shape of an ordinary intubation stylet that is familiar to all intubators, thus enableing the fiberoptic scope to be manipulated as an ordinary intubation style in any clinical situation, even when a direct line of sight is not possible. Since the holding sheath can sufficiently cover the total intraoral portion of a fiberoptic scope, it protects the scope from contacting the patient and prevents contamination. The scope thus needs not be sterilized after each use and can be used in other patient without delay. This feature not only increases the efficiency of the scope usage but also reduces the expansion for sterilization and repair, as well as prolonging the life of the scope, which is very delicate and expensive. The present invention thus provides not only a convenient and efficient alternative to conventional fiberoptic intubation technology that also has great promise as a major advancement in airway management, but its low cost shall also play a very important role in the new realities of today's healthcare industry.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
97 words
A fiberoptic intubation stylet apparatus, comprising: a holding element which comprises a soft plastic holding sheath and a holding strap attached to a first end of said holding sheath for firmly fastening a fiberoptic scope thereto, wherein said holding sheath is in a tubular form and said first end is an opened end for accommodation of said fiberoptic scope; and a malleable intubation stylet, which is longitudinally extended along and outside said holding sheath, being built into an outer wall of said holding sheath in order to enable said holding sheath being curled to a predetermined shape.
Claim 2
Dependent Claim
97 words
A fiberoptic intubation stylet apparatus, comprising: a holding element which comprises a soft plastic holding sheath and a holding strap attached to a first end of said holding sheath for firmly fastening a fiberoptic scope thereto, wherein said holding sheath is in a tubular form and said first end is an opened end for accommodation of said fiberoptic scope; and a malleable intubation stylet, which is longitudinally extended along and outside said holding sheath, being built into an outer wall of said holding sheath in order to enable said holding sheath being curled to a predetermined shape.
Claim 3
Dependent Claim
29 words
A fiberoptic intubation stylet apparatus, as recited in claim 1, wherein said holding sheath has a tapped second end for tightly fitting to a tip of said fiberoptic scope.
Claim 4
Dependent Claim
43 words
A fiberoptic intubation stylet apparatus, as recited in claim 1, wherein said holding sheath has a length enough to cover a total intraoral portion of said fiberoptic scope in order to protect said fiberoptic scope from contacting a patient and subsequently preventing contamination.
Claim 5
Dependent Claim
43 words
A fiberoptic intubation stylet apparatus, as recited in claim 2, wherein said holding sheath has a length enough to cover a total intraoral portion of said fiberoptic scope in order to protect said fiberoptic scope from contacting a patient and subsequently preventing contamination.
Claim 6
Dependent Claim
31 words
A fiberoptic intubation stylet apparatus, as recited in claim 2, wherein said holding sheath is transparent in nature in order to provide a clear visualization of an anatomy of said patient.
