Abstract
Abstract Post-operative drainage tubes, e.g., thoracic catheters, intercostal catheters and sump drain tubes, have a suture strip secured in piggy-back relation thereto. The drainage tube may then be fixed to the body of a patient by a suture which engages the suture strip, e.g., by being threaded through the joint between the suture strip and the drainage tube.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
132 words
In a post-operative drainage tube comprising an elongated tubular member formed of non-fibrous flexible water-proof plastic material, a proximal end portion adapted to be pulled through the body of a patient when the tube is inserted for drainage of material from the patient and a distal end portion comprising side openings in the tubular member through which material can enter the drainage tube from the patient, the improvement which comprises a suture strip formed of flexible waterproof plastic material welded to the exterior surface of said tubular member in superimposed relationship therewith, the joint between said tubular member and suture strip being capable of easy penetration by a suture needle to permit securing of the drainage tube by suturing to the body of a patient into which the drainage tube is inserted.
Claim 2
Dependent Claim
132 words
In a post-operative drainage tube comprising an elongated tubular member formed of non-fibrous flexible water-proof plastic material, a proximal end portion adapted to be pulled through the body of a patient when the tube is inserted for drainage of material from the patient and a distal end portion comprising side openings in the tubular member through which material can enter the drainage tube from the patient, the improvement which comprises a suture strip formed of flexible waterproof plastic material welded to the exterior surface of said tubular member in superimposed relationship therewith, the joint between said tubular member and suture strip being capable of easy penetration by a suture needle to permit securing of the drainage tube by suturing to the body of a patient into which the drainage tube is inserted.
Claim 3
Dependent Claim
17 words
A drainage tube of claim 1 wherein said tubular member is made of colorless, transparent plastic material.
Claim 4
Dependent Claim
31 words
A drainage tube of claim 2 wherein the plastic material of said suture strip contains a dye whereby the suture strip is clearly distinguishable by color from the colorless tubular member.
Claim 5
Dependent Claim
166 words
In a poSt-operative drainage tube comprising an elongated tubular member formed of non-fibrous flexible water-proof plastic material, a proximal end portion adapted to be pulled through the body of a patient when the tube is inserted for drainage of material from the patient, said proximal end portion comprising a closure cap, and a distal end portion comprising side openings in the tubular member through which material can enter the drainage tube from the patient, the improvement which comprises a suture strip formed of flexible waterproof plastic material, said strip being substantially circular in cross-section and welded to the exterior surface of said tubular member in superimposed relationship therewith substantially entirely along the length of said tubular member, the joint between said tubular member and suture strip being substantially a tangential contact between the member and strip capable of easy penetration by a suture needle to permit securing of the drainage tube by suturing to the body of a patient into which the drainage tube is inserted.
Claim 6
Dependent Claim
166 words
In a poSt-operative drainage tube comprising an elongated tubular member formed of non-fibrous flexible water-proof plastic material, a proximal end portion adapted to be pulled through the body of a patient when the tube is inserted for drainage of material from the patient, said proximal end portion comprising a closure cap, and a distal end portion comprising side openings in the tubular member through which material can enter the drainage tube from the patient, the improvement which comprises a suture strip formed of flexible waterproof plastic material, said strip being substantially circular in cross-section and welded to the exterior surface of said tubular member in superimposed relationship therewith substantially entirely along the length of said tubular member, the joint between said tubular member and suture strip being substantially a tangential contact between the member and strip capable of easy penetration by a suture needle to permit securing of the drainage tube by suturing to the body of a patient into which the drainage tube is inserted.
Claim 7
Dependent Claim
38 words
A drainage tube of claim 4 wherein said suture strip has a small section adjacent the distal end of the drainage tube removed to create an indication of the location of a side opening in said tubular member.
Claim 8
Dependent Claim
33 words
A drainage tube of claim 4 wherein said tubular member is formed of transparent, colorless plastic material and said suture strip is colored so that it is clearly distinguishable from the tubular member.
