DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0069] As best illustrated in FIG. 1, the present invention refers to a mounting device (1) for adapting a Foley urinary catheter (A) as a percutaneous endoscopic gastrostomy (PEG) catheter for enteral feeding, which in this case, said catheter has two upper branches (B), where an anti-reflux button (C) is connected to one of them and at its distal end it comprises an internal retaining balloon (D).
[0070] With reference to what is shown in FIG. 2 to FIG. 6, the device (1) comprises a radial clamp-type retention means (10) of the catheter to prevent it from migrating into the patient's stomach cavity, where said clamp (10) is secured in position by a locking button (20) for lateral coupling to the catheter and by a perimeter closure ring (30) that is inserted by pressure outside the locking button (20).
[0071] As best illustrated in FIG. 7 and FIG. 8, said clamp (10) has a central axial hole (11) having internal radial compression grooves (12) that stabilize the catheter to prevent its axial displacement and migration towards the interior of the abdominal cavity, where the interior grooves (12) have a semicircular shape section.
[0072] With reference to FIG. 8 in combination with FIG. 9, it is seen that the clamp (10) comprises means for retaining the locking button (20) and means for receiving the perimeter closure ring (30), where the means for retention of the locking button (20) comprise an outer wall (13) of the clamp (10), where said wall has a rounded contour and with a convergent negative inclination from top to bottom (see FIG. 9) and the means for reception of the ring (30) comprises a front horizontal channel (14) with a curved path arranged in the front upper edge of said clamp (10), which can also be seen in FIG. 7.
[0073] As best seen in FIG. 9, the clamp (10) comprises an upper face (15) and a lower face (16) from whose edges a perimeter spigot (17) projects; while the clamp is divided into a major base piece (110) laterally attachable to a minor base piece (120), where the major base piece (110) has an inner wall (111) facing an inner wall (121) of the minor base piece (120); thus, the inner wall (111) of the major base piece (110) is folded inward at a concave angle, which is complementary to the inner wall (121) of the minor base piece (120), which is folded outward at a convex angle.
[0074] Again referring to FIG. 8 in combination with FIG. 9, the major base piece (110) and the minor base piece (120) comprise outer radial flaps (18) projecting from the perimeter spigot (17) that comprise an upper face (181) and a lower opposite face (182) that is in contact with the external abdominal wall of the patient and where one of the flaps (18) comprises at a distal end a hook (19) with a through hole (191) for holding the catheter in the folded state.
[0075] As seen in FIG. 10 and FIG. 11, said locking button (20) comprises a substantially cylindrical body with an outer mantle (21), a lower face (22) and an upper face (23), in which body an upper portion (24) can be distinguished, an intermediate portion (25) and a lower portion (26), where the upper portion (24) comprises an axial central hole (241) from which a radial straight recess (242) extends to the outer mantle (21).
[0076] As best illustrated in FIG. 12, the intermediate portion (25) and the lower portion (26) comprise a radially inwardly extending recess (27), which has an interior wall (271) with divergent positive inclination from bottom to top; meanwhile, as seen in FIG. 13 and FIG. 14, the intermediate portion (25) comprises two horizontal recesses (251) opposed to one another, where each of them extends perimeter for approximately a quarter of a circumference from the entrance of the radial recess (27) backward.
[0077] As can be seen in FIG. 15 and FIG. 16, the aforementioned perimeter closure ring (30) has the shape of an open hoop with an internal diameter (34), in which ring (30) two curved arms (31) are distinguished and a front projection (32) with a semicircular outer notch (33) through which the catheter passes.
[0078] As shown in FIG. 17 and FIG. 18, in the process of coupling the ring (30) around the locking button (20), the curved arms (31) of the ring (30) are arranged and engaged in the horizontal recesses (251) of the locking button (20).
[0079] And as best seen from FIG. 19 to FIG. 23, the two base pieces (110) and (120) of the clamp (10) are laterally coupled to each other embracing the catheter (A), so that the internal diameter of the central axial hole (11) of the clamp (10), coincides with the size of the catheter (A) which it retains; in turn, the central axial hole (11) of the clamp (10) is axially aligned with the axial central hole (241) of the upper portion (24) of the locking button (20). The shape, size and inclination of the outer wall (13) of the clamp (10), coincides with the shape, size and inclination of the radial recess (27) of the locking button (20), allowing it to engage laterally in the clamp (10) and is retained therein by effect of the inclined walls preventing its axial displacement.
[0080] As best seen in FIG. 21, the front horizontal channel (14) arranged in the front upper edge of the clamp (10) is aligned in height with the two horizontal recesses (251) of the locking button (20) and the total length of said aligned channels and recesses corresponds to the total perimeter length of the perimeter closure ring (30). The semicircular outer notch (33) of the perimeter closure ring (30) is vertically aligned with the radial straight recess (242) of the locking button (20).
