Description

ADAPTABLE BED FOR HORIZONTAL, VERTICAL, AND INTERMEDIATE PARTIAL WORK, THAT IS ADDITIONALLY BEHAVIORED AS A BREAK AND RECOVERY BED DURING THE PREPARATION AND POST-DELIVERY STAGES.

DESCRIPTIVE MEMORY

The present invention relates to the medical industry associated primarily with hospital infrastructure. In particular, the present invention consists of an adaptable bed for horizontal, vertical and intermediate positions, which additionally behaves as a rest and recovery bed during the pre-delivery and postpartum stages.

BACKGROUND

In the state of the art there are different types of adaptable birthing beds, suitable for vertical, horizontal and intermediate positions, where birthing beds can be adapted to a bed made up of two substructures, a base and a backrest, with the backrest attached to the base by means of a hinge, through which said backrest pivots from a horizontal position to a vertical or intermediate position. In many cases, the base has a semicircular central opening at one outer end that facilitates vertical labor.

Although in the prior art a wide variety of beds can be found that allow to perform labor in a horizontal and vertical position, these beds consist of highly complex designs, which lead to a high cost of construction, and that do not place sufficient emphasis on improve patient comfort, which could result in greater efficiency both in labor and eventually in a stage before and after delivery itself, if an improved bed is provided that also serves as a rest and recovery bed during Pre-delivery and post-partum stages. In this sense, a better design of an adaptable birth bed, as proposed through the present invention, means at least 75% less in the cost of production and sale than a conventional bed of this nature. For example, document EP1685818 discloses a delivery bed, which describes lateral support devices for arms and feet, to be used by the patient during labor, which are configured to be coupled to the sides of the birthing bed The delivery bed has two substructures, a base and a backrest, joined together by a hinge, allowing the movement of the backrest with respect to the base from a horizontal position to a reclined position. In addition, the lateral support devices have adaptable length members, thanks to a telescopic extension, in order to serve as support for different positions of the delivery bed. These devices consist of a support section for feet of variable extension thanks to said telescopic extension, and a support section for arms that adjusts to the position of the foot support.

Thus, although the support devices for arms and feet of EP 1685818 consist of adaptable supports for the different geometric configurations of the delivery bed, these devices constitute a complex solution in terms of their design and construction. In addition, the support devices set forth in said document are located laterally, which for a horizontal or semi-horizontal position in labor can facilitate labor. However, if the delivery bed is configured in an upright position, the lateral supports do not necessarily result in an improvement or optimally facilitate the labor, since its location is not optimal for the patient.

Another example corresponds to EP 053581 1 A1, which describes a mattress for adaptable delivery beds, wherein the mattress has three air chambers inserted into the foam of the mattress. A lumbar chamber and an upper back are in the back of the birthing bed and another chamber is in the base.

However, the mattress described in EP 053581 1 A1, as well as the delivery bed, show a design focused exclusively on labor, where the three air chambers are specially designed to improve the conditions of delivery, and not to perform rest functions in pre-delivery or post-partum stages. In this way, various solutions can be found in the state of the art in which adaptive delivery beds are provided, enabled for labor in horizontal, vertical, and intermediate positions. However, as previously mentioned, the existing solutions have highly complex designs, which are not optimally adapted to the different configurations of the delivery bed, and which are designed specifically for labor, where the patient should be transferred to the delivery bed to begin the process and then be transferred again at the end of it.

On the other hand, the lateral supports for arms present in the prior art have a large number of moving parts, which must be additionally operated by an external energy source, which makes the construction of the bed more difficult and more expensive. In addition, since the supports are located at the bottom of each side of the birthing bed, they fulfill their support function preferably in a labor in a horizontal position, but do not efficiently fulfill their support function and help the patient during a vertical labor or in intermediate positions.

Therefore, there is a need in the state of the art to provide an adaptable delivery bed for horizontal, vertical and intermediate positions, which is capable of performing optimally during labor in each of the modalities mentioned, through a simpler and easier to build design, and that also serves for the rest and recovery of the patient in the pre-delivery and post-partum stages.

To correct the aforementioned deficiencies, an adaptable bed is presented to be used by healthy pregnant women for horizontal, vertical and intermediate positions, which has a design that allows its use both during labor and in the pre-pregnancy stages. childbirth and postpartum. This bed also has a horizontal bar located in the upper front part of the bed, which serves as a manual support during vertical labor and alternatively as a foot support during horizontal labor or intermediate positions, without hindering the work of the staff doctor to be at a sufficient height in relation to the professional assistant. The birthing bed that is presented does not require a system of "leg loops", which support the popliteal space (back of the knee joint). Conventional birth beds have this system of support legs that produce decrease and stagnation of blood flow in the lower extremities increasing discomfort for women and, above all, the risk related to vascular complications. Instead, a support system for the lower extremities has been designed in combination with the tensile force for the bid, through an ergonomic support bar that supports the traction of the pregnant woman's arms and the foot support. through two lateral support elements, preferably inclined at 40 ^e . Said support bar consists of a three-curve bar type element that can serve as support for labor, especially in the case of effort in an upright position. This accessory is used only at the time of birth or at the time the pregnant woman requires it, previously, to exercise the force of the bid.

By containing support elements for feet, the uncomfortable, anti-ergonomic and traditional "leg" is eliminated, present in the prior art, and responsible for many thrombotic disorders in women close to 40 years. This is significant because the user in the process of delivery simultaneously exerts two forces: a first one of grip, traction and bidding and a second one of resistance that opposes the support of feet as counter-force.

Thus, the support bar has the following properties:

one . It is incorporated into the bed, and likewise, if the circumstances require it, it is removable.

2. It has a geometry that allows the holding of hands in a variable way and simultaneously to the containment of the feet.

3. Due to its location and geometry, it allows the action of the professional without obstructing the action performed by the user during childbirth.

On the other hand, thanks to the characteristics of the bed, it can be used in the pre-delivery and post-partum stages, thus avoiding unnecessary transfers of the patient and improving the process from an integral point of view, which includes the different stages associated with the birth process. These possibilities They are determined by the geometric variation of the different alternatives and fixations proposed by the bed in its various reclineings or configurations.

In a horizontal position it can be used as a rest bed in pre-delivery and post-partum, since it is a bed set like any other bed, including conventional bedding; while its recline in intermediate positions favors the vertical position, and finally, in a 90 ° recline it can be used as an exercise structure.

Finally, from tests performed on the present invention, a decrease in the number of surgical vaginal deliveries (forceps), and the number of normal deliveries with episiotomy has been found. In this sense, the adaptable bed corresponds to equipment that emphasizes the continuous care of users, an incomparable advantage given the adaptability that it has for each stage of the process.

The present invention consists of an adaptable bed for vertical, horizontal and intermediate positions, which additionally allows its use in the pre-delivery and post-partum stages, which comprises:

A support structure (100) formed by:

A base structure (10), formed by a plurality of metal parts;

A seat structure (120) arranged fixedly on the upper part of the base structure (10);

A backrest structure (130) pivotally fixed around a rotating shaft (131); Y

A support bar (200) that is fixed to the seat structure (120) at each of its ends, wherein said support bar extends transversely to the adaptable bed on the outside of the front end thereof, at a certain height.

Said adaptable bed further comprises:

A seat mattress (30), arranged on the seat structure (120);

A back mattress (40), fixed on the back structure (130);

A mattress pillow (50) fixed at the rear end of the backrest structure (130);

Side covers (60), fixed to the sides of the support structure (100); Y

Two support elements (70) for feet fixed on each side of the support bar (200).

In a preferred configuration of the invention, said support bar (200) comprises two lower horizontal sections (220, 221) that are fixed to the support structure, two lateral vertical sections (240, 241) extending to a certain height , and an upper horizontal section (270) that travels transversely outside the front end of the adaptable bed. Alternatively, and as seen in Figure 3, the support bar (200) comprises at each end two horizontal lower sections (220, 221), which project parallel to the sides of the bed and away from the support structure (1 10); wherein said lower sections are then projected perpendicularly in two vertical sections (240, 241). Both vertical sections respectively end in new perpendicular folds, which project two horizontal sections (250, 251), transversely to the bed and in the direction of the center of it; both horizontal sections at the same time end in new perpendicular folds, projecting two vertical sections (260, 261) respectively; the vertical sections (260, 261) end in perpendicular folds towards the center of the bed to join in a single horizontal and transverse section (270), so that the support bar has a stepped shape from a front view.

The support structure (100) consists of metal parts that correspond to steel tubes, preferably square tubes, where said tubes are made of structural steel and are fixed by welding or other fixing means such as bolts.

The base structure (1 10) is a parallelepipeidal structure, with a stop bar (1 1 1) at its rear end, and said rotary axis (131) can be arranged on the base structure (1 10) by means of shaft supports ( 1 12) fixed in a later section of the base structure (1 10).

In addition, said support structure (1 10) additionally comprises four wheels (61) with brakes fixed respectively at the lower corners of the base structure (1 10), wherein said base structure (1 10) further defines an interior space of about 35 cm high by 70 cm. wide and about 70 cm. deep to store other labor accessories. It also has adaptable safety railings (not shown in the figures), simple to fix.

The support elements for feet (70) have an inclination between 30 ° and 50 °, where an inclination of 40 ^e is preferably used.

The seat mattress (30) has, in an alternative configuration, a removable section at its outer end, in a semicircular shape, which allows the anatomical space that allows spontaneous or assisted extraction of the newborn to be generated. in urgent situations. To cover this space, the adaptable bed comprises a cushion (80) of the same structural quality as the rest of those that make up the bed and that complements the shape of the seat mattress (30), so that said cushion is optionally incorporated into the seat mattress (30) allowing the adaptable bed to have a rectangular and complete surface.

On the other hand, the seat (30) and backrest mattresses (40), as modular and adaptable elements, allow the adaptable bed of the present invention to be configured in its two primary functions, as a delivery bed and as a rest bed in the Pre and postpartum stages. These mattresses have a thickness of between 10 cm. and 30 cm., and preferably 15 cm., where this attribute guarantees the absorption capacity of the loads generated by the human body, without diminishing its comfort and structural capacity. Considering the above, due to its modular parts, the present invention is transformed into a traditional bed, with the proper attributes of a rest mattress with the appropriate thickness and density, thus providing comfort and ergonomics during rest in a horizontal position.

In one configuration of the invention, as shown in Figures 4 and 5, the rotary axis (131) is arranged on the base structure (10), such that in a vertical position of the adaptable bed (see figure 2) the back mattress (40) is removed, while for horizontal operation and intermediate positions, said back mattress (40) is located on the back structure (130).

On the other hand, in an alternative configuration such as that shown in Figure 7, the rotating shaft (131) is arranged on the seat structure (120) by means of shaft supports (1 12) fixed to said structure, in such a way that the back mattress (40) is arranged on the backrest structure (130) for all working positions of the adaptable bed.

The support bar (200) is ergonomic, and is incorporated in the support structure (1 10) of the adaptable bed, therefore it does not constitute an external element of the bed, allowing the user to adopt various delivery positions using The same bid element. During the birth procedure, the adaptable bed according to the present invention allows three clear positions to be adopted, privileging the delivery in an upright position, sitting at 90 ^e , in a reclined position at 135 ^e , and in a complete horizontal position for birth horizontal.

However, in alternative configurations of the invention, a one-piece mattress can be provided, which remains in place at the time the support structure (100) is transformed.

The geometric and positioning adaptability of the adaptive bed of the present invention is achieved thanks to manual force without resorting to any electrical or hydraulic mechanism. Two people are needed to perform the operation, keeping the pregnant person in the adaptable bed. For the pre-delivery and post-partum stage the adaptable bed adapts to a horizontal position and the seat, back and mattress mattresses allow rest without the need to resort to another bed.

In resting position it is observed as a traditional bed, which can be dressed with conventional bedding.
