Abstract
Abstract A suction catheter having a distal end portion with an opening for insertion into a patient's airway. A proximal end portion is connected to a resilient unobstructed tubular member on which a valve operates to control fluid flow through the member. The valve which is biased to a normally closed condition will open the tubular member when activated and will return to its normally closed condition when not activated. A downstream connector is attached to a source of suction.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
212 words
A suction device for removing material from the trachea of a patient during ventilation comprising, a catheter having an internal lumen and opposed front and rear ends with the front end including a suction opening, front and rear couplings supporting said catheter and a protective sleeve normally enclosing said catheter and in turn operatively associated with said front and rear couplings, said catheter connected at its rear end to said rear coupling, said front coupling including an internal seal for slidable receipt of the outer surface of said catheter whereby said catheter front end may be inserted into and withdrawn from the trachea of said patient, including suction control means means connected to said rear coupling for applying and controlling suction to said catheter, said control means including a longitudinally oriented resilient tubular member having a straight through, normally unobstructed internal lumen, compression means associated with said tubular member for sealing off said internal lumen in a normally closed position, said compression member also operable solely by external operator applied manual depression to open up said tubular member internal lumen so as to apply suction to said catheter internal lumen, said compression means being continually urged to a closed position and normally in a completely closed position when not being manually activated.
Claim 2
Dependent Claim
212 words
A suction device for removing material from the trachea of a patient during ventilation comprising, a catheter having an internal lumen and opposed front and rear ends with the front end including a suction opening, front and rear couplings supporting said catheter and a protective sleeve normally enclosing said catheter and in turn operatively associated with said front and rear couplings, said catheter connected at its rear end to said rear coupling, said front coupling including an internal seal for slidable receipt of the outer surface of said catheter whereby said catheter front end may be inserted into and withdrawn from the trachea of said patient, including suction control means means connected to said rear coupling for applying and controlling suction to said catheter, said control means including a longitudinally oriented resilient tubular member having a straight through, normally unobstructed internal lumen, compression means associated with said tubular member for sealing off said internal lumen in a normally closed position, said compression member also operable solely by external operator applied manual depression to open up said tubular member internal lumen so as to apply suction to said catheter internal lumen, said compression means being continually urged to a closed position and normally in a completely closed position when not being manually activated.
Claim 3
Dependent Claim
31 words
The device of claim 1, said rear coupling including a passageway operationally connecting said catheter lumen with said tubular member and to said suction source when said valve member is opened.
Claim 4
Dependent Claim
52 words
The device of claim 1, said rear coupling including a front portion attached to said sleeve and a rearwardly disposed flange in turn supporting the base of a leaf clamp comprising said valve member, said rear coupling further including a stem rearwardly extending from said flange for receipt of said tubular member.
Claim 5
Dependent Claim
67 words
The device of claim 1, said device further including an adapter capable of attachment to a tracheal tube connected to said front coupling, said adapter having a ventilator side port adapted for connection to a ventilator and wherein said internal seal through which said catheter tube is slidably received prevents inflation of said sleeve during operation of the ventilator when the adapter is connected to the patient.
Claim 6
Dependent Claim
68 words
The device of claim 1, said sleeve in the form of an expandable, collapsible plastic sheath normally enclosing said catheter and having opposed front and rear ends respectively sealingly attached to said front and rear couplings, said rear coupling movable towards said front coupling when said catheter is forwardly advanced with accompanying collapse of said sleeve as when the catheter front end is inserted into the patient's trachea.
Claim 7
Dependent Claim
35 words
The device of claim 1, said valve member positioned to act externally on opposed wall portions of said tubular member so as to collapse said tubular member so as to effectively shut off fluid therethrough.
Claim 8
Dependent Claim
20 words
The device of claim 1, including means external of said valve for preventing the accidental operation of said valve member.
Claim 9
Dependent Claim
71 words
The device of claim 3, including external prevention means for preventing the accidental operation of said valve member, said prevention means including said front portion of said rear coupling, said front portion upwardly extending at least a major portion of the upward extent of said leaf clamp such that a patient laying an arm across the valve member will contact said front portion and thus reduce contact with said leaf clamp.
Claim 10
Dependent Claim
143 words
A suction device comprising a catheter having an internal lumen and front and rear ends with the front end including a suction opening for insertion into and withdrawal from the trachea of a patient, a resilient tubular member having a straight through, normally unobstructed internal lumen and further opposed ends and adapted to move between open and closed positions, said catheter end in turn operatively connected to one end of said tubular member and the other end of said tubular member operatively connected to suction means such that when said tubular member is in its open position suction is operationally applied to said catheter and valve means for continually urging and thus effectively biasing said tubular member to a normally closed position said valve means in turn operable to its fully open position from its fully closed position solely by external manual depression.
Claim 11
Dependent Claim
143 words
A suction device comprising a catheter having an internal lumen and front and rear ends with the front end including a suction opening for insertion into and withdrawal from the trachea of a patient, a resilient tubular member having a straight through, normally unobstructed internal lumen and further opposed ends and adapted to move between open and closed positions, said catheter end in turn operatively connected to one end of said tubular member and the other end of said tubular member operatively connected to suction means such that when said tubular member is in its open position suction is operationally applied to said catheter and valve means for continually urging and thus effectively biasing said tubular member to a normally closed position said valve means in turn operable to its fully open position from its fully closed position solely by external manual depression.
Claim 12
Dependent Claim
29 words
The device of claim 9, said valve means acting externally on said tubular member such that the opposed walls thereof are effectively flattened thereby to said normally closed position.
Claim 13
Dependent Claim
39 words
The device of claim 10, said valve means including a depression mechanism whereby an operator can depress such so as to allow the tubular member to return to its open position against the closing action of the valve means.
Claim 14
Dependent Claim
37 words
The device of claim 11, said valve depression mechanism adapted to immediately shut off the fluid path of said tubular member and immediately return it to its normally closed position when the mechanism is released after actuation.
Claim 15
Dependent Claim
20 words
The device of claim 9, including means external of said valve for preventing the accidental operation of said valve means.
