Abstract
Abstract An anatomical model for teaching the intubation of the human trachea has epiglottis and tongue parts simulated by an assembly which is pivotally movable and biased into a normal position by elastic resilience of the tongue part. The larynx of the model is exposable through the mouth on manipulation of the tongue and epiglottis parts with the blade of a laryngoscope. A primary use of the model is in teaching non-specialist personnel to insert an endotracheal tube correctly in the trachea for resuscitation purposes. A jaw and a trachea may be movably mounted for teaching appropriate procedures for difficult cases.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
An anatomical model for teaching the intubation of the human trachea said model having a larynx part, mouth parts, a tongue part, an epiglottis part joined to the base of the tongue part, an anteriorly movable lower jaw part and a pivotal mounting carried by the lower jaw part and positioned adjacent the junction of the epiglottis and tongue parts, the epiglottis and tongue parts being simulated by an assembly which is pivotally movable about said pivotal mounting and biassed into a normal position by elastic resilience of the tongue part, said elastic resilience and anterior movability of the tongue part with the jaw part co-operating to simulate visual exposure of the larynx part by manipulation through the mouth parts with a laryngoscope.
Claim 2
Dependent Claim
123 words
An anatomical model for teaching the intubation of the human trachea said model having a larynx part, mouth parts, a tongue part, an epiglottis part joined to the base of the tongue part, an anteriorly movable lower jaw part and a pivotal mounting carried by the lower jaw part and positioned adjacent the junction of the epiglottis and tongue parts, the epiglottis and tongue parts being simulated by an assembly which is pivotally movable about said pivotal mounting and biassed into a normal position by elastic resilience of the tongue part, said elastic resilience and anterior movability of the tongue part with the jaw part co-operating to simulate visual exposure of the larynx part by manipulation through the mouth parts with a laryngoscope.
Claim 3
Dependent Claim
24 words
A model according to claim 1 having lip parts formed of resiliently deformable material, said lip parts simulating the lips of a human mouth.
Claim 4
Dependent Claim
19 words
A model according to claim 1 having a formation representing a retro-laryngeal pathway in addition to the larynx part.
Claim 5
Dependent Claim
20 words
A model according to claim 1 having a set of interchangeable upper dentures providing a choice of upper teeth formations.
Claim 6
Dependent Claim
21 words
A model according to claim 1 in which the larynx is resiliently mounted for posterior movement under externally applied manual pressure.
Claim 7
Dependent Claim
37 words
A model according to claim 5 in which the larynx is carried by adjustable means operable to position the larynx over a range of chosen natural positions from which it is resiliently displaceable by said manual pressure.
