Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
159 words
A tracheostomy device comprising: a neckplate having an access opening; a trach head swivellingly connected to said neckplate at said access opening; a tube adapted for insertion into a patient's breathing passage, said tube connected to said trach head; and connection means for swivellingly connecting said trach head to said neckplate without deformation of the trach head or neckplate and without thermal processing; wherein said connecting means includes a pair of bearing members and a pair of corresponding bearing sockets to receive said bearing members in seating relationship, said pair of bearing members connected with one of said neckplate or trach head and said pair of bearing sockets formed in the other of said neckplate or trach head: and wherein said connection means further includes a cam surface associated with each of said bearing members for engagement with a portion of the other of said trach head and neckplate when said bearing members are seated within said bearing sockets.
Claim 2
Dependent Claim
159 words
A tracheostomy device comprising: a neckplate having an access opening; a trach head swivellingly connected to said neckplate at said access opening; a tube adapted for insertion into a patient's breathing passage, said tube connected to said trach head; and connection means for swivellingly connecting said trach head to said neckplate without deformation of the trach head or neckplate and without thermal processing; wherein said connecting means includes a pair of bearing members and a pair of corresponding bearing sockets to receive said bearing members in seating relationship, said pair of bearing members connected with one of said neckplate or trach head and said pair of bearing sockets formed in the other of said neckplate or trach head: and wherein said connection means further includes a cam surface associated with each of said bearing members for engagement with a portion of the other of said trach head and neckplate when said bearing members are seated within said bearing sockets.
Claim 3
Dependent Claim
24 words
The device of claim 1 wherein said bearing members are connected with said neckplate and said bearing sockets are formed in said trach head.
Claim 4
Dependent Claim
47 words
The device of claim 1 wherein said trach head includes a tube receiving portion and a flange portion, wherein said bearing members are connected with said neckplate and said bearing sockets are formed in said tube receiving portion and wherein said cam surface engages said flange portion.
Claim 5
Dependent Claim
46 words
The device of claim 1 wherein each of said bearing sockets includes a bearing socket portion and a corresponding entry means for enabling said bearing members to seat within said bearing socket portion without deformation of said neckplate or said trach head and without thermal processing.
Claim 6
Dependent Claim
19 words
The device of claim 4 wherein said entry means includes a slot extending from said corresponding bearing socket portion.
Claim 7
Dependent Claim
31 words
The device of claim 5 wherein said slot includes a passage dimension sufficiently large to permit passage of said bearing members through said slot and into said corresponding bearing socket portion.
Claim 8
Independent Claim
142 words
A method of swivellingly connecting a trach head to a neckplate without deformation of the trach head or neckplate and without thermal processing, the steps of said method comprising: providing a neckplate and a trach head wherein one of said neckplate and said trach head includes a pair of bearing members and the other includes a pair of corresponding bearing sockets, each of bearing sockets having a bearing socket portion and a corresponding entry means comprising a cam surface for enabling said bearing members to seat within said bearing socket portion for rotation about an axis of rotation; positioning said pair of bearing members in said entry means and moving said bearing members along said cam surface into seating position within said bearing sockets; and rotating said trach head about said axis of rotation at least about 90° relative to said neckplate.
Claim 9
Independent Claim
142 words
A method of swivellingly connecting a trach head to a neckplate without deformation of the trach head or neckplate and without thermal processing, the steps of said method comprising: providing a neckplate and a trach head wherein one of said neckplate and said trach head includes a pair of bearing members and the other includes a pair of corresponding bearing sockets, each of bearing sockets having a bearing socket portion and a corresponding entry means comprising a cam surface for enabling said bearing members to seat within said bearing socket portion for rotation about an axis of rotation; positioning said pair of bearing members in said entry means and moving said bearing members along said cam surface into seating position within said bearing sockets; and rotating said trach head about said axis of rotation at least about 90° relative to said neckplate.
Claim 10
Dependent Claim
13 words
The method of claim 7 wherein said trach head is rotated about 180°.
Claim 11
Dependent Claim
30 words
The method of claim 7 wherein said bearing members are moved into seating position within said bearing sockets by movement along a direction generally perpendicular to said axis of rotation.
Claim 12
Dependent Claim
26 words
The method of claim 7 wherein said trach head includes an opening and said method includes securing a tube in said opening following said rotation step.
Claim 13
Dependent Claim
13 words
The method of claim 10 wherein said trach head is rotated about 180°.
