Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A method for supplying fluid to a space in a fluid transport system, or draining said space which is located downstream of a cavity having an inlet and an outlet, characterised by inserting a predetermined length of a tube (10) made of a flexible elastic material and having an inherent tendency to coil up along at least said predetermined length, into said cavity via the inlet thereof by means of a guide (15) inserted in the tube and made from a flexible but unelastic material, said guide (15) tending to straighten itself in the unactuated state with a force exceeding the force of the coiling-up tendency of the tube (10), such that, upon withdrawal of the guide (15) from the tube (10), the tube (10) can coil up within the cavity until a substance supplied to the cavity straightens the tube (10) and transports it to the said space via the cavity outlet in order to supply or take up fluid within said space.
Claim 2
Independent Claim
164 words
A method for supplying fluid to a space in a fluid transport system, or draining said space which is located downstream of a cavity having an inlet and an outlet, characterised by inserting a predetermined length of a tube (10) made of a flexible elastic material and having an inherent tendency to coil up along at least said predetermined length, into said cavity via the inlet thereof by means of a guide (15) inserted in the tube and made from a flexible but unelastic material, said guide (15) tending to straighten itself in the unactuated state with a force exceeding the force of the coiling-up tendency of the tube (10), such that, upon withdrawal of the guide (15) from the tube (10), the tube (10) can coil up within the cavity until a substance supplied to the cavity straightens the tube (10) and transports it to the said space via the cavity outlet in order to supply or take up fluid within said space.
Claim 3
Dependent Claim
121 words
A tube equipment for the supply of fluid, or for draining, comprising a tube (10) of flexible elastic material, preferably silicone rubber, characterised in that said tube (10) has along at least a part of its length a tendency to coil up in the unactuated state, a guide (15) being insertable into said tube (10) and consisting of a flexible but unelastic material, said guide, in its unactuated state, tending to straighten itself with a force exceeding the coiling-up force of the tube (10), and, after insertion into the tube (10), maintaining the tube (10) in a straightened-out state for insertion into a cavity via a passage and permitting, after withdrawal, coiling-up of the tube (10) length within the said cavity.
Claim 4
Dependent Claim
121 words
A tube equipment for the supply of fluid, or for draining, comprising a tube (10) of flexible elastic material, preferably silicone rubber, characterised in that said tube (10) has along at least a part of its length a tendency to coil up in the unactuated state, a guide (15) being insertable into said tube (10) and consisting of a flexible but unelastic material, said guide, in its unactuated state, tending to straighten itself with a force exceeding the coiling-up force of the tube (10), and, after insertion into the tube (10), maintaining the tube (10) in a straightened-out state for insertion into a cavity via a passage and permitting, after withdrawal, coiling-up of the tube (10) length within the said cavity.
Claim 5
Dependent Claim
32 words
A tube equipment as claimed in claim 2, characterised in that the tube wall (10) is per forated (13) over a distance adjacent the end adapted to be inserted in the cavity.
Claim 6
Dependent Claim
32 words
A tube equipment as claimed in claim 2 or 3, characterised in that the tube end (10) adapted to be inserted into the cavity carries an agent (14) traceable by X-ray technique.
