Abstract
Abstract An orotracheal tube pacifier is disclosed. The orotracheal tube pacifier includes an orotracheal tube, a pacifier portion for receiving the orotracheal tube, fastener means for holding securely the pacifier portion around the patient's head without the need for taping and the ultimate bruising, a face plate to which the fastener means and the pacifier portion are securely attached to, the face plate being relatively large as a safety precaution to hold the pacifier portion, a collet locking device fitting on the face plate and will not slipping or coming loose, and nipples affixed to the face plate and being designed to reduce the amount of palatal grooving.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
222 words
A device for oral intubation, comprising a face plate having a thickened central portion with a central aperture therethrough and a large peripheral flange to prevent the device from being swallowed, said flange being shaped to contact a patient's face beneath the nose, a hollow, resilient bite protector having an open proximal end inserted in said aperture, and a distal end having a through hole, a lock member comprising a core having a plug protruding into the end of the bite protector, the plug extending through the central face plate aperture, and into the distal end of the bite protector, for locking both the bite protector and the lock member to the face plate, said lock member further having a peripheral flange abutting a front surface of the face plate, and an externally tapered and threaded collet portion split by longitudinal cuts into plural segments, each capable of limited movement in a radial direction, and an internally tapered and threaded nut engaged with the threads on the collet portion, and an orotracheal tube extending entirely through said lock member, said face plate, and said bite protector through-hole, whereby the tube is prevented from contacting the upper palates and said tube can be secured without damage in the lock member by tightening said nut, thus forcing the collet segments inward against the tube.
Claim 2
Independent Claim
222 words
A device for oral intubation, comprising a face plate having a thickened central portion with a central aperture therethrough and a large peripheral flange to prevent the device from being swallowed, said flange being shaped to contact a patient's face beneath the nose, a hollow, resilient bite protector having an open proximal end inserted in said aperture, and a distal end having a through hole, a lock member comprising a core having a plug protruding into the end of the bite protector, the plug extending through the central face plate aperture, and into the distal end of the bite protector, for locking both the bite protector and the lock member to the face plate, said lock member further having a peripheral flange abutting a front surface of the face plate, and an externally tapered and threaded collet portion split by longitudinal cuts into plural segments, each capable of limited movement in a radial direction, and an internally tapered and threaded nut engaged with the threads on the collet portion, and an orotracheal tube extending entirely through said lock member, said face plate, and said bite protector through-hole, whereby the tube is prevented from contacting the upper palates and said tube can be secured without damage in the lock member by tightening said nut, thus forcing the collet segments inward against the tube.
Claim 3
Dependent Claim
37 words
The invention of claim 1, wherein said thickened central portion has a counterbore on its front face, for receiving the open proximal end of said bite protector, and for seating the peripheral flange of said lock member.
Claim 4
Dependent Claim
77 words
The invention of claim 1, wherein said orotracheal tube has a distal portion extending past the hole in the bite protector into the mouth of a patient, and only part of said distal portion is provided with a flexible bellows portion that allows the tube to bend easily at the back of the throat without crimping, to prevent bending of that portion within the mouth so as to avoid damage to the upper palates of the patient.
Claim 5
Dependent Claim
48 words
The invention of claim 1, further comprising a pair of retaining straps affixed to opposite sides of the face plate, said straps being of sufficient length to pass around the head of the patient, and having quick-release fasteners thereon providing for continuous length adjustment for different sized patients.
Claim 6
Dependent Claim
36 words
The invention of claim 1, wherein the face plate has a pair of side holes, one on either side of the central aperture, each adapted to receive an auxiliary tube for feeding, medication or the like.
Claim 7
Dependent Claim
22 words
The invention of claim 1, further comprising means for retaining the nut on the collet, so that the nut cannot be lost.
Claim 8
Dependent Claim
41 words
The invention of claim 1, wherein the bite protector is a pacifier having a rounded end in which said through hole is formed, a round top surface for protecting the hard palate, and a round bottom surface for engaging the tongue.
Claim 9
Dependent Claim
31 words
The invention of claim 1, wherein the lock member holds the orotracheal tube and the bite protector on a common axis to prevent the tube from being bitten by the patient.
Claim 10
Dependent Claim
25 words
The invention of claim 1, wherein the plug of the lock protector has a peripheral lip, providing a snap fit into the face plate aperture.
