Multiple conduit drainage device

DETAILED DESCRIPTION What we claim is: 1.
A unitary multiple conduit flexible drainage device in which the individual conduits may be parted at their distal ends upon application of a parting force, comprising: a common manifold, a plurality of generally parallel adjacent conduits, said conduits being in fluid communication with said common manifold at their proximal ends; and at least two generally parallel frangible membranes joining adjacent conduits, whereby the adjacent conduits may be readily parted from their distal ends.
2.
The drainage device of claim 1, in which the conduits are generally rectangular in cross-section.
3.
The drainage device of claim 1, in which a pair of generally parallel membranes are used.
4.
The drainage device of claim 1, in which the conduits and membranes are made of silicone.
5.
The drainage device of claim 1, in which the conduits and membranes are made of thermoplastics or thermoplastic resins.
6.
The drainage device of claim 1 in which the membranes are integrally formed with the conduits.
7.
The drainage device of claim 1, in which holes are provided in the distal ends of the conduits to facilitate drainage.
8.
A unitary multiple conduit flexible drainage device in which the individual conduits may be parted at their distal ends upon application of a parting force, comprising: a common manifold, a pair of generally parallel adjacent conduits, said conduits being in fluid communication with said common manifold at their proximal ends; and at least two generally parallel frangible membranes integrally formed with and joining adjacent conduits, whereby the adjacent conduits may be readily parted from their distal ends.
9.
The drainage device of claim 8, in which the conduits are generally rectangular in cross-section.
10.
The drainage device of claim 8, in which the conduits and membranes are made of silicone.
11.
The drainage device of claim 8, in which the conduits and membranes are made of thermoplastics or thermoplastic resins.
12.
The drainage device of claim 8, in which holes are provided in the distal ends of the conduits to facilitate drainage
