Abstract
Abstract A pair of sterile nestable closure caps having a female end and a male end, and a method of aseptically protecting the interconnectable ends of first and second tubes in a liquid drainage system with the caps. In the method, the ends of the first and second tubes are disconnected, the end of the second tube is inserted into the female end of the sterile nested caps, and the male end of the sterile nested caps is inserted into the end of the first tube to close the ends of the first and second tubes. The nested caps are then separated, whereby the ends of the disconnected first and second tubes are aseptically closed by the caps.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
112 words
A method of aseptically protecting the interconnectable ends of first and second tubes in a liquid drainage system with a nestable pair of sterile caps, with the nested caps having a female end and a male end, comprising the steps of: disconnecting the ends of the first and second tubes; inserting the end of the second tube into the female end of the sterile nested caps and the male end of the sterile nested caps into the end of the first tube to close the ends of the first and second tubes; separating the nested caps, whereby the ends of the disconnected first and second tubes are aseptically closed by the caps.
Claim 2
Independent Claim
112 words
A method of aseptically protecting the interconnectable ends of first and second tubes in a liquid drainage system with a nestable pair of sterile caps, with the nested caps having a female end and a male end, comprising the steps of: disconnecting the ends of the first and second tubes; inserting the end of the second tube into the female end of the sterile nested caps and the male end of the sterile nested caps into the end of the first tube to close the ends of the first and second tubes; separating the nested caps, whereby the ends of the disconnected first and second tubes are aseptically closed by the caps.
Claim 3
Dependent Claim
28 words
The method of claim 1 wherein the end of the second tube is inserted into the nested caps prior to inserting the nested caps into the first tube.
Claim 4
Dependent Claim
54 words
The method of claim 2 wherein the nested caps are retained in a sterile package, and including the steps of: opening the sterile package; and removing the sterile nested caps from the opened package with the second tube after inserting the end of the second tube into the female end of the nested caps.
Claim 5
Dependent Claim
78 words
The method of claim 1 wherein said first tube comprises a catheter having a main lumen, said second tube comprises a drainage tube having a drainage lumen which communicates with said lumen when the catheter and drainage tube are connected, the distal end of the drainage tube is inserted into the female end of the nested caps, and the male end of the nested caps is inserted into the main lumen of the catheter adjacent its proximal end.
Claim 6
Dependent Claim
29 words
The method of claim 4 wherein said drainage tube includes a connector adjacent its distal end, and said connector is inserted into the female end of the nested caps.
Claim 7
Dependent Claim
35 words
The method of claim 1 wherein each of said caps has a male and a female end, and the male end of an inner cap is nested in the female end of an outer cap.
Claim 8
Dependent Claim
31 words
The method of claim 1 including the steps of: removing the caps from the ends of the first and second tubes; and connecting the ends of the first and second tubes.
Claim 9
Dependent Claim
30 words
The method of claim 7 including the step of inserting the male end of the cap removed from the first tube into the female end of the other removed cap.
Claim 10
Dependent Claim
93 words
A liquid drainage system closure means, comprising: a catheter having a main lumen and a proximal end; a drainage tube having a drainage lumen and a connector adjacent its distal end; a pair of sterile nested closure caps, with the nested caps having a female end removably receiving and closing said drainage tube connector, with the nested caps having a male end removably inserted into the main lumen of the catheter to close its proximal end, and with said caps being separable to asceptically close the ends of the catheter and drainage tube.
Claim 11
Dependent Claim
93 words
A liquid drainage system closure means, comprising: a catheter having a main lumen and a proximal end; a drainage tube having a drainage lumen and a connector adjacent its distal end; a pair of sterile nested closure caps, with the nested caps having a female end removably receiving and closing said drainage tube connector, with the nested caps having a male end removably inserted into the main lumen of the catheter to close its proximal end, and with said caps being separable to asceptically close the ends of the catheter and drainage tube.
Claim 12
Dependent Claim
46 words
The drainage system closure means of claim 9 wherein each of said closure caps has a male end and a female end, and the male end of at least one of said caps is separably nested in the female end of the other of the caps.
Claim 13
Dependent Claim
20 words
The drainage system closure means of claim 10 wherein each of said caps comprises a hollow generally conically shaped member.
Claim 14
Dependent Claim
26 words
The drainage system closure means of claim 10 wherein the closure cap which is nested inside the other cap is less rigid than said other cap.
Claim 15
Dependent Claim
29 words
The drainage system closure means of claim 10 wherein the male end of either of said caps is nestable in the female end of the other of the caps.
