Abstract

The invention relates to a device for use in the prenatal preparation of and easing of labor in pregnant women. Said device has a longitudinal dilatory body (1) which can be expanded along the entire length thereof and can be positioned in the region of the exitus of the birth canal so that it is partially inside and partially outside the vagina. The inventive device is provided with an elongated widening (4) at the end of the expandable body (1) which is perpendicular to the said body and which is used to define the innermost position of the dilatory body (1) when it is placed against the outer labia.

Description

Device for the birth preparation and birth facilitation of the pregnant woman

The invention relates to a device for the birth preparation and birth facilitation of the pregnant woman, with an elongate expansion body which is expandable in its entirety and which can be positioned in the region of the birth canal exit in such a way that it is partly in the vagina and partly outside it.

Such a device is described in German Offenlegungsschrift 19715724. The stretch body is designed as an elongated body which is expandable as a whole and which has an expandable waist which, in the area of the hymenal hem, is guided self-centering during use. In a preferred embodiment, the expansion body is designed as a balloon, to the end of which, when used, is connected to a filling hose.

Due to the expansion of the elongated body, the vaginal canal can be temporarily expanded in the known device and thus the birth canal including the hymenal hem can be pre-stretched to facilitate childbirth. With this training and stretching effect, episiotomies and perineal tears as well as an undesirable lowering of the pelvic floor can be significantly reduced. In a first clinical pilot study, the decrease in perineal incidence in first-time mothers was approximately 35%.

DE 2622111 AI describes a dilating probe for expanding the cervix. She has one inflatable but not stretchable cover. This is fixed in place by an inner pear-shaped section and inside the sheath by a shield. An application within the meaning of the invention is therefore out of the question.

Starting from the device described in DE-Al 19715724, the design of which is made the subject of the present application with all the details, the aim of the present invention is to make the known device simpler, safer and particularly easy to handle.

According to the present invention, this aim is achieved in that an elongated, transverse to the expansion body widening is provided at the end of the expansion body when used outside the vagina, which serves to limit the innermost position of the expansion body in the system against the outer labia ,

In this way, it is not only prevented that the expansion body can undesirably migrate inward in the vagina, where there is a risk of injury to the cervix, but at the same time it ensures that the expansion body is always within the hymenal hem. In this particularly simple manner, an effective positioning of the expansion body in the area of the hymenal hemisperforms itself, which is achieved in the known device by the waist of the expandable body.

In the context of the present invention, the expansion body can be designed as a balloon with or without a waist. The waist has a particularly valuable additional gymnastic effect in that the balloon is pressed outwards by the pregnant woman by tensing the muscles. This takes place with the help of the vaginal, pelvic floor and abdominal muscles of the pregnant woman, which simulates the expulsion phase at birth by pressing. The balloon is then pushed inwards again by means of the widening until the widening reaches the contact position.

Precisely because of the widening, the pregnant woman can safely handle the device herself. By lightly pressing your fingertips against the outside of the enlargement, she introduces the device into the inside of the vagina. The counter movement then takes place, as explained above, in the trained pregnant woman through the same muscles which are responsible for squeezing the baby. Initially, the pregnant woman can help with the squeezing by moving the expansion body outwards by pulling on the widening.

A particularly advantageous embodiment of the connection of the balloon to the plate, a neck of the balloon being inserted through a hole in the plate, is characterized by further features in the subclaims. Embodiments of the invention are explained below with reference to the drawing. It shows

Fig. 1 shows a schematic longitudinal section through a first embodiment, Fig. 2 shows a second embodiment with inflatable

Balloon in side view, Fig. 3 is a front view of Fig. 2 in the direction of

Arrow III and Fig. 4 shows a cross section according to IV-IV of Fig. 3rd

Fig. 1 shows a rigid expansion body 1, preferably made of a physiologically harmless plastic, e.g. made of appropriately hard latex, silicone or a thermoplastic. In the sleeve-shaped expansion body 1, a nut 2 is molded, with which it can be screwed against a plate-shaped widening 4 by means of a screw 3. The widening 4 preferably consists of the same material as the expansion body 1. Depending on the physiological conditions or the progress of the training, an expansion body 1 of the appropriate size can be used.

The expansion body 1 has a conical section 9 which tapers towards the widening 4. Instead of the conical shape, the expansion body 1 could also have a pear shape with a waist, approximately according to the balloon 5 shown in FIG. 2.

Fig. 2 shows an expansion body 1 in the form of an inflatable balloon 5, for example made of latex or a similar rubber-like material, which is connected to a widening 4 in the form of a plate 12. Both parts can also be integrally molded by injection molding getting produced. A filling hose 8 is connected to the balloon 5, the other end of which is connected to an air pump (not shown) with a pressure gauge. As is usual with blood pressure measuring devices, a shut-off valve is expediently provided on the manometer, which enables the setting of a specific air pressure inside the balloon 5. For example, if the pregnant woman starts her exercises in the 38th week of pregnancy, she can increase the internal pressure of the balloon for her daily exercises in steps of approximately 10 to 20 mm Hg until a maximum pressure of approximately 160 mm Hg is reached.

The balloon 5 has a waist 10 with a short distance behind the plate 12. With the help of this waist 10, the balloon 5 centers itself in the area of the perineum. Towards the inside of the vagina, with increasing filling, the balloon widens from its slim starting shape 19, which facilitates insertion, as shown by broken lines, to a piston-like shape 17, which is particularly suitable for massage of the vaginal and pelvic muscles.

3 shows the design of the plate 12 with widened end regions 13. In the middle, the plate 12 has a bore 14 for receiving a neck 11 of the balloon 5. The filling hose 8 is integrated into the neck 11 by means of a sleeve 18, for example shrink wrapped. Fig. 4 shows the cross section of the plate 12. Through its concave design by means of a groove 16 towards the expansion body, a comfortable contact of the plate 12 in the genital area is to be made possible, so that the balloon 5 is prevented from slipping into the vagina.
