The gasbag (2) is provided with an inflating and deflating pipe (21), which connects the electric inflating and deflating control box (3) to implement an inflating and deflating function.
The elevated swelling rate is greater that the natural swelling rate.
The swelling clay mineral preferably is a swelling clay mineral containing fluorine.
An aqueous solution is passed into the reservoir to contact the swelling agent, thereby causing the swelling agent to swell and substantially block the permeable zone.
In this method, contact with the swelling liquid (2) in the swelling step (A) is attained by spraying the swelling liquid (2) onto both sides of the hydrophilic polymer film (1) in a gaseous phase.

Inflation may be accomplished by injecting an inflation medium into the inflation pocket (56) .
An inflator (20) provides inflation gas through the opening (18) in the airbag (14).
Inflation may be performed through a catheter connected to a readily accessible inflation port.
The second portion may be configured such that the inflation lumen (205) enables inflation of the inflatable balloon (202).
The shaft may include one or more inflation lumens and a plurality of openings defined therein that are in fluid communication with the inflation lumen or lumens.
An inflator (36) is arranged in an inflator opening (16) in the center of the rear panel (14).
The drainage tube includes a swell layer and a cast layer formed about the swell layer.
The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28 °C, or a chemical co-blowing agent, or combinations thereof.
