PELVIC TISSUE VISCOELASTIC STRETCHING DEVICE

Abstract

The pelvic tissue viscoelastic stretching device before childbirth consists of, on the one hand, a flexible basic body (1) in the form of an inverted quadrangular pyramidal structure extending in a support and positioning tab (4) and comprising an upper face (5) designed to be positioned beneath the uterus and a smaller lower face (6) designed to be positioned near the perineum, connected by an inactive front face (7) and by three active stretching faces, that is a posterior lower face (8) and two lateral faces (9) located on either side of it, and on the other, by three balloons (2, 3) respectively attached to the stretching faces (8, 9) of the basic body (1) and which can be inflated, in particular with physiological serum, to ensure posterior pressing against the sacrum and lateral pressing on the lifting muscles, up to an overall volume corresponding essentially to the head of a baby on birth.

Claims

1. A device for pelvic tissue viscoelastic stretching prior to childbirth, characterized in that it comprises: on the one hand, a flexible basic body (1), in the form of an inverted quadrangular pyramidal structure extending in a support and positioning tab (4) and comprising a wide upper face (5) designed to be positioned beneath the perineum, connected by an inactive anterior face (7) and by three active stretching faces, that is, a posterior face (8) turned toward the rear and the bottom and two lateral faces (9) on either side of it, and on the other hand, by three balloons (2, 3) respectively attached to the stretching faces (8, 9) of the basic body and which can be inflated, in particular with physiological serum, to ensure posterior pressing against the sacrum and lateral pressure against the lifting muscles, to reach an overall volume corresponding essentially to the head of a baby on childbirth.

2. The device of claim 1, characterized in that the upper face (5) of the basic body (1) is essentially rectangular with the larger sides corresponding to the lateral stretching faces (9) while the lower face (6) of this body is essentially square.

3. The device of claim 1, characterized in that in the inflated condition, the balloon (2), attached to the posterior stretching face (8) has a volume larger than that of the two balloons (3) attached to the lateral stretching faces (9) and is situated below these two lateral balloons.

4. The device of claim 1, characterized in that it comprises a tube for the simultaneous inflation (11) of the two lateral balloons (3) and an independent inflation tube (10) for the posterior balloon (4), the three balloons being supported by the support and positioning tab (4).

5. The device of claim 4, characterized in that it comprises management devices allowing the control, testing and regulation of the inflation of the balloons (2, 3).

6. The device of claim 1, characterized in that the support and positioning tab (4) is concave toward the front.

7. The device of claim 1, characterized in that the faces of the basic body (1) are concave.

8. The device of claim 1, characterized in that the inactive anterior face (7) is hollowed in the form of a cylinder section to ensure the protection of the urinary urethra.

9. The device of claim 1, characterized in that it consists of sterilized double or single purpose biocompatible material.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The characteristics of the device forming the subject of this invention are described in greater detail with reference to the attached non-limiting drawings in which:

[0042] FIG. 1 is a longitudinal schematic view of the stretching device,

[0043] FIG. 2 is a top view of this stretching device,

[0044] FIG. 3 is a lateral view of this stretching device.

PREFERRED EMBODIMENT FOR CARRYING OUT THE INVENTION

[0045] According to FIGS. 1, 2 and 3, the device comprises essentially a flexible basic body 1 and three balloons liable to be filled with physiological serum, that is, a posterior balloon 2 and two lateral balloons 3.

[0046] The basic body 1 is essentially in the form of an inverted quadrangular pyramidal section and extends in a support and positioning tab 4 which is concave towards the front.

[0047] The basic body 1 comprises more specifically a large upper face 5, essentially rectangular in shape, designed to be positioned under the uterus and a smaller lower face 6, essentially square, designed to be placed towards the perineum.

[0048] The upper face 5 and the lower face 6 of the basic body 1 are connected by an inactive anterior face 7 hollowed out in the form of a cylindrical section to protect the urinary urethra and by three active stretching faces, that is a posterior face 8 turned downward and to the rear and two lateral faces 9 located on either side of it.

[0049] The faces 5, 6, 7, 8 and 9 of the basic body 1 are concave.

[0050] The three balloons 2, 3 are respectively attached to the posterior face 8 and the lateral faces 9 of the basic body 1.

[0051] The support and positioning tab 4 supports a tube 10 for inflating the posterior balloon 2 and a tube 11 for the simultaneous inflation of the two lateral balloons 3.

[0052] In the inflated condition, the posterior balloon 2, attached to the posterior stretching face 8, has a volume larger than that of the two balloons 3 attached to the lateral stretching faces 9 and is situated below these two lateral balloons 3.
