    DESCRIPTION OF SOME EXAMPLES OF EMBODIMENT

    [0077] Some examples of embodiments of the present invention are described below with reference to FIGS. 1 to 17.

    [0078] As shown in FIGS. 1 to 9, according to a possible example of the present invention, a retention device (50) is provided configured to be coupled to the free end of a urinary catheter and retain this free end on an element external to the user's body, wherein the retention device (50) is formed by a rigid body having a monobloc body with: [0079] a first portion (51) extending in a longitudinal direction “X” and having an inner recess (54) for receiving and accommodating an end part of a urinary catheter, [0080] wherein from the rear part and upper end of the first portion (51) emerges a tab (53) configured to releasably fasten the retention device (50) to an element external to the user's body, and [0081] a second portion (52), which extends in a second transverse “Y” direction, and wherein the second portion (52) has an interior recess (62) for receiving and accommodating at least a portion of the sliding valve of the urinary catheter.

    [0082] In this embodiment, the tab (53) extends from the uppermost end of the first portion (51) downward to almost the lowermost portion of the first portion 51. The extension direction of the tab (53) is slightly inclined with respect to the longitudinal direction “X”, that is, the tab (53) moves slightly away from the surface of the first portion (51) as it extends downwards (see FIGS. 3 and 4).

    [0083] In this embodiment, the first portion (51) is constituted by an elongated half-barrel body (i.e. with a “C” shaped cross section), which is closed at the top by a stop portion (55) and where the recess (54) inside the groove has dimensions such as to receive, in a tight manner, a part of the connection section (70a) of a urinary catheter. This stop portion (55) at the top has the function of supporting an anti-leakage element to isolate the outlet port of the catheter. As shown in FIG. 1, the first portion (51) decreases in width from the upper part to the lower part where it is coupled to the second portion (52), that is, it has a body in the form of a conical throne segment.

    [0084] The stop portion (55) is formed by a flat element of low thickness that acts as a support for an anti-leakage element (56), with a convex surface, which protrudes from the inner part of the stop portion (55) of the first portion of the retention device, see FIGS. 1, 3 and 4. This stop portion 55 may have, for example, a circular shape (see FIG. 5).

    [0085] Preferably, the anti-leakage element (56) or sealing element is configured by a protruding element on the inner part of the stopper portion (55) of the first portion (51) of the retention device, and wherein the anti-leakage element (56) is configured to fit perfectly inside the extreme opening of the catheter or urinary catheter connection tube, thereby producing its sealing and thereby preventing any amount of liquid from leaving the outside of the retention device. FIG. 16 shows how the anti-leakage element (56), with a slightly semi-circular contour, has entered through the opening and is mounted inserted in the end of the catheter or urinary catheter connection tube.

    [0086] In this example of embodiment, the second portion (52) is constituted by an elongated body extending in a transverse direction, but of shorter length than the first portion (51), also shaped as a half-barrel (i.e., with a “C”-shaped cross section, see FIG. 3). The rear part of the half-rod-shaped surface is represented by (61) and the inner recess by (62), where the inner recess (62) that is created inside this “C” shaped section has dimensions such as to receive, in a tight manner and inserted under pressure, at least a part of the sliding valve (71) of the urinary catheter (which corresponds to the part where the activation button (72) is located). Further, as clearly seen in FIGS. 8 to 9, the transverse body of the second portion (52) is open at one of its ends, forming an open left side section (60) so that a portion of the slide valve (71) can protrude along with the activation button (72) that is at the end. On the other end, the transverse body of the second portion (52) is closed by an anti-opening wall (57), wherein the anti-opening wall (57) has an inner face (57a) and an outer face (57b), and has a small opening (58) at its bottom, wherein this opening (58) is for accommodating a tactile recognition system of the position of the catheter for use by people with reduced vision. In addition, the second portion (52) has an opening (59) in the form of a “C”-shaped inlet in its central and lower part for the passage of the lower connection section (70b) of the catheter. FIG. 1 clearly shows that the central opening (59) is fully aligned with the longitudinal axis “X” of the first portion (51).

    [0087] With reference to FIGS. 10 to 16, the same example of a retention device (50) as the previous figures are depicted therein, but in this case with the free end part of a urinary catheter (10) conveniently inserted into the retention device (50). In the specific case illustrated, a urinary catheter (10) known as a two-way catheter is shown, where only the free end of the catheter and a small part of the flexible tube (74) have been depicted, but not the rest of the flexible tube (74) and the introduction section (14), shown in FIG. 17, through a urethra in a user's urinary bladder. The urinary catheter (10) has at its free end or connection end a valve (71-72) configured as a slide valve in the form of a plunger that moves inside a cylinder, arranged transversely. In the case of the urinary catheter (10) shown, this is a two-way type catheter. FIGS. 10 to 16 of the catheter (10) also show a junction section (73) that connects a balloon arranged at the introduction end (not shown) that inflates with a liquid that enters through a secondary channel of the tube towards the introduction end where the balloon is. At the end of the body 70a an opening is formed in which a connection element (not depicted in the figures), such as a urine bag, can be connected. Using this balloon, the urinary catheter (10) can be fixed to the urinary bladder in its position.

    [0088] This specification does not explain the internal functioning of the urinary catheter (10) or the valve (71-72), since it is the same as that described in European patent no. EP2872194A1.

    [0089] In particular FIG. 16 shows a possible configuration of the end part of the catheter (10), which has an end provided with a central orifice (76) in a staggered form that decreases in diameter, and which ends above in a mouth (76a). In this figure it is clearly seen how the convex protuberance (56) fits perfectly within the upper mouth (76a) of the central orifice (76).

    [0090] FIG. 16 also shows how the part opposite the button of the valve (71-72) is arranged in contact with the inner face (57a) of the anti-opening wall (57). In this position the valve is closed, that is, preventing the passage of fluid through the interior of the central orifice (76).

    [0091] In particular FIG. 17 shows the retention device (50) with the end part of the urinary catheter inserted therein, which is hung upside down by means of the tab on the top of the underwear (75) of a user. It is seen how the tube (74) is hidden underneath the underwear until reaching the bladder. The direction of urine flow towards the discharge end has also been illustrated. In this way, by being fixed at a point of the user's clothing (75) such that the tube (74) is not uncomfortable, it is possible to prevent the undesirable traction of the tube (74), which generally causes injury and bleeding of the user, allowing the user to perform a physical activity with total normality and comfort.

    [0092] Although reference has been made to a specific embodiment of the invention, it is clear to a person skilled in the art that the retention device and retention device assembly described are susceptible to numerous variations and modifications, and that all the details mentioned can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the attached claims.
