Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 225 words
A tube for use in an intubation which comprises: a first tubular body (10) having a first conduit (12) and a second conduit (13) both extending in the longitudinal direction of said first tubular body (10), the second conduit (13) having a bevelled distal end defining an opening whose axis is inclined to the axis of the first tubular body (10), a flange (14) extending substantially perpendicular to said longitudinal direction, and a side hole (15) formed in the first conduit (12) at a predetermined distance from said flange; a flexible second tubular body (20) connected at its distal end to the proximal end of said first conduit (12) so as to communicate with said first conduit (12); a hollow needle (30) slidably received by said first conduit (12) and by said flexible second tubular body (20); and a liquid-tight seal (40) provided between the inner surface of said second tubular body (20) and the outer surface of said hollow needle (30), characterized in that the flange (14) has means (14b) for securing it to the wall of the aorta, and the distance (L) between the flange (14) and the proximal edge (15a) of said side hole (15) is substantially equal to the distance (M) between said flange (14) and the proximal edge (13a) of the distal end opening (13b) of said second conduit (13).
Claim 2
Dependent Claim 225 words
A tube for use in an intubation which comprises: a first tubular body (10) having a first conduit (12) and a second conduit (13) both extending in the longitudinal direction of said first tubular body (10), the second conduit (13) having a bevelled distal end defining an opening whose axis is inclined to the axis of the first tubular body (10), a flange (14) extending substantially perpendicular to said longitudinal direction, and a side hole (15) formed in the first conduit (12) at a predetermined distance from said flange; a flexible second tubular body (20) connected at its distal end to the proximal end of said first conduit (12) so as to communicate with said first conduit (12); a hollow needle (30) slidably received by said first conduit (12) and by said flexible second tubular body (20); and a liquid-tight seal (40) provided between the inner surface of said second tubular body (20) and the outer surface of said hollow needle (30), characterized in that the flange (14) has means (14b) for securing it to the wall of the aorta, and the distance (L) between the flange (14) and the proximal edge (15a) of said side hole (15) is substantially equal to the distance (M) between said flange (14) and the proximal edge (13a) of the distal end opening (13b) of said second conduit (13).
Claim 3
Dependent Claim 22 words
A tube as set forth in claim 1, wherein said first conduit (12) has a greater diameter than said second conduit (13).
Claim 4
Dependent Claim 40 words
A tube as set forth in claim 1, wherein said flange (14) is provided at substantially mid point in the longitudinal direction of said first tubular body (10), said substantially mid point containing the first and second conduits (12, 13).
Claim 5
Dependent Claim 26 words
A tube as set forth in claim 1, wherein said liquid-tight seal comprises a plug (40) fitting to the outer wall of said hollow needle (30).
Claim 6
Dependent Claim 39 words
A tube as set forth in claim 3, wherein said flange (14) is provided with a plurality of slots (14b) for passing a thread for sewing said first tubular body (12) to a wall (2b) of the aorta (2).
Claim 7
Dependent Claim 55 words
A tube as set forth in claim 1, further including a connector (50) provided on the other end of said second tubular body (20) and a knob (31) provided on the rear end of said hollow needle (30) and detachably connected to said connector (50) on said other end of said second tubular body (20).
Claim 8
Dependent Claim 32 words
A tube as set forth in claim 6, wherein said hollow needle (30) is restricted in a fluid-tight manner at a predetermined portion (30c) along the length of said hollow needle (30).
Claim 9
Dependent Claim 50 words
A tube as set forth in claim 1, further including a third tubular body (60) connected at its one end to the other end of said second conduit (13) to communicate with the latter, and a three-way cock (61) attached to the other end of said third tubular body (60).
Claim 10
Dependent Claim 55 words
A tube as set forth in claim 1, wherein said hollow needle (130) has a knob (131) fixed to the rear end thereof, said knob (131) having a through hole (131a) communicating with the hollow (130b) of said hollow needle, and a filter (131c) mounted thereon so as to cover said through hole (131 a).
