INTRODUCER AND PLACER OF REPAIRS IN TUBULATIONS

Abstract: Introducer and placer of repairs in tubulations is a tubular mechanical device, rigid or flexible, which presents a store place where it is possible to store a tube repair (12), and it presents controls (8, 9) to introduce and to place the repair (12) at the right position in the inner tube wall. The introducer presents an ogive (1) to open the way, niches (4, 6, 7) to store the repair (12), the repair (12) hold system (5, 11), a trigger to set free and to place the repair (12) on the tubulation's right position.

Description: INTRODUCER AND PLACER OF REPAIRS IN TUBULATIONS Mechanical device, tubular, with compartment to store tubulation repair and with commands to introduce and to place the repair in a pre-determined point in the tubulation internal wall The repair services in hard-accessed tubulations, has been a constant worry to the involved professionals The leakage caused by perforation in a mansory built-in hydraulic tubulation has required the rupture and withdrawal of part of the wall's revetment It could be repaired accessing the tubulation's internal wall, through one of the ends The device proposed in this report is also an alternative in cases of chimney of small diameters, with linkages in specific points throughout the tubulation and it is hard to access through the tubulation's external wall to make a repair In the medicine field, there is the need of putting repairs, called prothesis, inside the tubulation of the digestive and vascular systems, in this field, there are several types of devices, called catheter, destined to introduction and placement of the prothesis in specific points of the internal wall of veins and arteries The introducer and placer of repairs in tubulations, described in this report, consist in a tubular device, rigid or flexible, with external diameter smaller than the tubulation internal diameter, has in one of the ends, space to store the repair and has cables and stem in its interior with access through the other end, for handling and placement of repair in the tubulation The figures described below, show the main functional elements of the device Besides not specifying the dimensions, they don't show the real proportionality of the elements that compose the device The lack of proportionality in the drawings, is justified because the dimensions and proportion of the elements varies individually according to the application, size, and type of the repair and the tubulation's internal diameter The figure 1, shows the device with the ogive(l), the spacer tube(6), the scabbard(7), the maniple(8) of the scabbard(7), the maniple(9) of the spacer tube(6), the trigger(lθ) and detail(17) The figure 2 shows the detail(17), with the base(2) of the ogive(l), the guide tube(3), the multilumem tube(4) and the drag wires(5) The figure 3 shows the base(2) of the ogive(l) with the chain holes(l l) of fitting and fixation of the wires(5) The figure 4 shows the guide tube(3), the multilumem tube(4) and the drag wires(5) The figure 5 shows detail of the way of cramping the repair(12) in the drag wires(5), the drag wires(5) ends inside the chain holes(l l) in the base(2) of the ogive(l), the repair(12) involving the multilumem tube(4) and stored inside the scabbard(7) and aligned with the spacer tube(6) The repair(12) has opening of arches(13) for cramping and fixation in the wires(5) The figure 6 shows the cut(18), the scabbard(7), the maniple(8) of the scabbard(7), the maniple(9) of the spacer tube(6), and the trigger(lθ) The figure 7 shows the cut(18) with the guide tube(3), the multilumem tube(4), the wires(5), and the spacer tube(6) The figure 8 shows the cut(16), the maniple(9) of the spacer tube(6), the trigger(lθ) with locking screw(14), and setting point(15) of the wires(15) in the trigger(lθ) The figure 9 shows the detail(16) with the multilumem tube(4), the wires(5), and the spacer tube(6) The figure 10 shows constructive form where the multilumem tube(4) is replaced by cylindrical tube(19) and connector(20), shows the base(2) of the give(l) with the chain holes ( 1 1), the guide tube(3), and the wires(5) The figure 1 1 shows the base(2) of the give(l) with the connector(20) set in the base(2) Shows the chaps(21) of the connector(20) The device is built according to its application, repair type and size, and internal diameter of the tubulation Special attention is taken in the construction of the end that stores the repair(12) The repair(12) is built-in in the interior of the scabbard(7), involving the multilumem tube(4), occupying the empty of spacer tube(6) and steed by the opening of arches(13) in the drag wires(5) The device is introduced, in the tubulation being repaired, until the repair(12) reaches the section of the tube where the defect is The positioning can be previewed measuring the distance between the end and the defective section of the tube The positioning of the repair of the repair can be monitored by X-ray, ultrasound and others Once positioned the repair in the desired section, make the axial recoil of the scabbard(7) sliding it axially in relation to the spacer tube(6), so the conjunct formed by the ogive(l), guide tube(3), multilumem tube(4), the wires (5), spacer tube(6), and the repair(12) remain still, liberating the repair(12) from its niche The repair(12) goes through a self-expansion until it presses the internal wall of the tube, the repair(12) is still set, through the opening of arches(13) in the wires(5) During this stage is possible to make an evaluation of the repair(12) positioning related to the section of the tube, if it is necessary to make an adjustment, it is possible to displace axially the repair(12) pushing the conjunct, and specially the ogive(l), forward, the repair(12) moves with the conjunct because of the drag of the wires(5) set in the opening of arches(13) of the repair(12) After the adjustment, is bring into action the trigger(lθ) that gather the wires(5) inside the multilumem tube(4), disconnecting definitively the repair(12) from the device The multilumem tube(4), showed in figures 2, 4, 5, 7, and 9 with straight section in triangular shape, may have the polygonal section with plurality of sides or rounded section The shape of the section of the multilumem tube(4) depends on the constructive shape of the repair(12), its bending and fittings The figure 10 shows the tube(19) of rounded section, without longitudinal holes for the passage of the wires(5), replacing the multilumem tube(4) The drag wires(5) run loose in the gap between the guide tube(3) and the flat tube(1 ), penetrate into the chaps(21 ) of the connector(20) and point to the chain holes(l l) ofthe base(2) The axial recoil of the scabbard(7) is obtained manually, keeping still the maniple(9) of the spacer tube(6) and displacing axially the maniple(8) of the scabbard(7) in the direction of the maniple(9) of the spacer tube(6) The trigger(lθ) is a rigid stalk-cylindrical piece, placed in the end opposite to the ogive( l). has a small cylindrical surface with external screw(14) that is screwed in the body of the maniple(9) of the spacer tube(6) The wires(5), that have one of the ends free to set in the opening of arch(13) of the repair(12) and to penetrate in the chain holes(l l) of the ogive(l), have the other extremity set in the base(15) of the trigger(lθ) Bring into action the trigger(lθ), consists in disconnecting(14) the trigger(lθ) from the maniple(9) of the spacer tube(6) and displace the trigger(lθ) axially away from the maniple(9) Although during the text and drawings, the scabbard is cited and represented as a cylindrical tube with uniform section, it may have geometrically the shape of a tube of scaled diameters Part of the tube, next to the ogive(l), may have the diameter larger than the scabbard(7) body to store repairs that need big niches
