DESCRIPTION OF THE INVENTION

(5) This invention relates to a device to exercise the pelvic floor muscles, in women, through the vaginal canal, useful for the treatment or prevention of pathologies related to the loss of muscle function in this region.

(6) The device comprises a main component (A), a secondary component (B) and optionally a set of external weights (P).

(7) The main component (A), as shown in FIG. 3, comprises a substantially cylindrical body (C), a vertical rod (H), two crosspieces (7) and two supports (9).

(8) The body (C) has a substantially cylindrical shape, of the type of menstrual tampons, being composed of an intravaginal portion, with a rounded tip (1) and an intermediate portion (2) and, an extravaginal portion (3).

(9) The portions (1 and 2) of the body (C) are specially adapted to be in contact with the levator ani muscle (21), thus exerting a resistant force in the perpendicular direction on the said muscle and opposed to its contraction (arrow 1), as shown in FIG. 4.

(10) The extravaginal portion (3) of the body (C) comprises, on its upper side, a hole (10) suitable for the insertion of the rod (H), and on each of its sides, a hole (8), which are suitable for the insertion of the crosspieces (7).

(11) The rod (H) has a lower region (4), an intermediate region (5) and an upper region (6), inserting itself, through its lower region (4), in the hole (10) to connect mechanically with the cylindrical body (C), forming an internal angle preferably of about 100?. The lower region (4) forms an internal angle preferably of 100? with the intermediate region (5). The intermediate region (5) and the upper region (6) form an internal angle, preferably of 45?, to fit the external weights (P), which increase the resistance to contraction of the muscles of the pelvic floor of the user, generating a displacement of the rod (H) in the mid-sagittal plane of the user's body.

(12) The pair of supports (9), have an essentially rectangular shape and slightly curved, with a concave side, so as to be supported in the antero-medial region of the user's thigh. Each of these supports (9) is attached to a rigid beam (7), through the lateral holes (8), of the body (C), in order to make the connection with the extravaginal portion (3) of said body (C). This connection is achieved by means of a 3D articulation, thus enabling the rotation in any of the three orthogonal axes.

(13) The secondary component (B), as shown in FIG. 2, comprises two vertical beams (11), a graduated ruler (12), two support bases (13) and a horizontal beam (14).

(14) The vertical beams (11) are rigid and adjustable in length, each comprising an upper end and a lower end.

(15) The horizontal beam (14) is rigid, with a circular, length-adjustable section, arranged at the upper ends of each vertical beam (11) to connect them.

(16) The support base (13), rigid and substantially rectangular in shape, is mounted on each of the lower ends of the vertical beams (11).

(17) The ruler (12) can be graduated in mm or inches and is arranged vertically and perpendicular to the horizontal beam (14) at its midpoint. The graduated ruler (12) allows the evaluation and quantification of the displacement of the upper region (6) of the rod (H), allowing the monitoring of the different types of muscle contraction performed against resistance (concentric, eccentric, isometric).

(18) The weights (P) are placed, when necessary, in the intermediate region (5) of the rod (H), in an external location to the user's body, through a ring in the upper part of the weight.

(19) Consequently, there is no need to remove the body (C) from the device of the invention, after its insertion into the vaginal canal, to modify the load applied to the device.

(20) The weights (P) present different loads, to be used according to the needs and objectives to be reached, each one of them can vary between 5 and 40 g, with a 5 g gradient, being possible to associate more than 1 weight each time, as for example x, x+1, x+2 and y.

(21) In FIG. 4, arrow 1 represents the resistant force, applied in the direction of the muscle fibers, which is obtained by the action of the device of the present invention. The movement of the body (C) is rotational, instead of the linear movement exerted by the device of the state of the art, represented in FIG. 1. Thus, the force applied through the device of invention is closer to that imposed by manual reinforcement (bidigital), enhancing, in a substantially advantageous way, the cephalic and postero-anterior displacement of the muscles mentioned above.

(22) The device of the present invention can be made totally or partially of rigid material, such as plastic, metal, among others, preferably recyclable and light materials, so as not to induce discomfort.

(23) The cylindrical body (C) is preferably made of rigid material, such as plastic, metal, among others, preferably recyclable and light materials, so as not to induce discomfort. It may or not be coated with sterilisable material by physical and/or chemical means, such as radiation, pressure and steam, or by contact with chemical sterilisation agents.

(24) The application of the device may be performed by adding a disposable coating of material compatible with the vaginal mucosa, such as a condom, which allows the device to be used by one or more users.

(25) The device comprises a coating that is easy to sanitize and sterilization substances can be applied. Its easy handling allows it to be used both in the hospital and at home.

(26) The extravaginal portion (3) of the body (C) and each of the rigid rods (7) has a preferential angle of 45? in respect to the longitudinal axis of the cylindrical body (C).

(27) The configuration of the secondary component (B), in the shape of an inverted U, ensures that the cylindrical body (C) does not move longitudinally, in the vaginal canal, during the execution of the exercises.

(28) A number of embodiments of the device may also include the addition of at least one sensor, selected from the group of pressure sensors, motion sensors, rotation sensors, slope sensors, acceleration sensors, among others.

(29) The device can also be monitored via an electronic application connected to a suitable software for this purpose.

(30) Following the recommendations of the American College of Sports Medicine, the device can be associated with a pelvic floor muscle strength exercising program in order to develop hypertrophy, endurance or power.

(31) The device of this invention is particularly suitable for exercising the pelvic floor muscles in users positioned in the dorsal decubitus position.

(32) The main component (A), in particular the body (C), is related to the action resulting from the contraction of the pelvic floor muscles, which, being in direct contact with the levator ani muscle, exerts a resistant force in the perpendicular direction on that muscle and opposed to its contraction.

(33) Its application is especially advantageous for strengthening the pelvic floor muscles, especially the levator ani, adjusting the type of contraction (isometric, concentric, eccentric) and the strength resistant to the type of exercise involved (hypertrophy, endurance, power), appropriate to the specific dysfunctions of each patient.

(34) The main distinguishing features are as follows: Possibility of evaluation and qualitative and quantitative monitoring of each exercising session to strengthen the pelvic floor muscles; Special action directed to the levator ani muscle, by the contraction type exercised (isometric, concentric, eccentric) in reaction to the resistant force; Adjustment of load and type of force exerted to the intended target (hypertrophy, endurance, power), appropriate to the specific dysfunctions of each patient; Implementation of different loads during the same exercising session, without the need to remove the body of the device from the user's intravaginal region; Maintenance of the correct positioning of the body of the device, thanks to the ergonomics provided by the concave supports resting on the user's thighs.
