Description

Improved ergonomic bed base and mattress.

Object of the invention

The present invention relates to a bed base and mattress, which have been specially conceived as elements therapeutic, to offer an ideal support base for the body during sleep, and that allow functional procedures in the recovery of long stay patients.

The object of the invention is to achieve a bed base and a mattress that, in addition to offering the user a configuration Anatomical or ergonomic for proper body support, offer optimal benefits, for people who require long stays in bed, to avoid the appearance of local ischemia with the consequent ulcers or sores and loss of muscle mass and bone decalcification.

Background of the invention

As is known, for many years it has been of Common use the conventional rectangular mattress. However, this type of mattress does not provide adequate anatomical support and a alignment of the spine to the user during sleep. Indeed, the support that this mattress offers is irregular in general,  causing the existence of unequal pressures in our body. This results in serious discomfort and the appearance of injuries. when it is necessary to stay in bed for periods prolonged The harmful effects of maximum pressure points which generates the mattress in contact with the body, they grow exponentially with the passage of time.

In motionless people who keep long bed periods blood circulation is inhibited at the points of maximum pressure and after a certain time the skin becomes red and swells, producing supine ulnar ischemia in heels, calves, buttocks and back, suffering among others conditions of pulmonary congestion, atrophy and loss of mass muscle and bone decalcification among others.

To prevent this from happening, these people they must be turned at regular intervals in order to prevent the consequences described at the points of maximum pressure and improve pulmonary fluid drainage, as well as the mobility of members to minimize bone and muscle conditions. This what family members or nurses normally perform one or two hour intervals, with the required overexertion that could generate back injuries, especially when the Sick is of remarkable corpulence.

When the person is on the bed for a long time a type of bed or related is required that allow a whole series of functions that serve to replace the fault of total or partial motor skills of the patient, so that he can perform certain functions as easily as possible, with minimal help from third parties.

In recognition of these inadequacies, they have designed beds and mattresses that allow, within the same Work plane, back lift or back area in where the patient rests, as well as the area of the feet up at different heights, all through the corresponding connecting rod or crank mechanism, or with the corresponding electrical or hydraulic elements.

Although there are motorized swivel beds, which allow flipping, these are designed primarily for patients with damage to the spine, so that the patient is tightly confined. This tight confinement situation It is very unpleasant to many patients, causing nausea and  facilitate the development of ischemia.

There are very sophisticated beds, with the consequent economic repercussion that this supposes, like those of low air loss, where the patient is supported by a number of Inflated bags whose pressure is adjusted to maximize the area on which the patient's weight rests, thus minimizing the skin contact pressure. Also known are beds of liquid silicone, which constitute a very complex solution for Get the mobility of the patient.

Another of the most frequent conditions they suffer people who require an extended stay in bed are ischemia in the thumbs of the feet, which result in sores or ulcers, produced by the overpressure of the quilt or quilt. This is currently solved by manual methods such as bandage toes, the use of chairs near the bed where the quilt or quilt rests or the use of baskets that prevent direct contact, all these solutions incorporate a series of inconveniences such as the ease of circulation of cold air around the feet, a non-stable support of the comforter or quilt and the inconvenience of having an external element in the bed.

Description of the invention

The invention proposes to alleviate these inconveniences. posing an ergonomic mattress design whose profile allows achieve an isobaric contact surface or said of another so that each area of the body in contact with the support mattress equal pressure, distributing it evenly and eliminating maximum pressure points, thus facilitating the circulation of the blood and eliminating the chances of causing ischemia local.

The design of these profiles can be fixed and measure for each person, so that the curves that make it up match the specific anatomical shape of each individual, this can be achieved in a fixed way or by conventional elements Home automation Or, they can be made with measuring ranges standards, as in textile clothing.

The mattress and box spring will incorporate a flap in the lower end or footboard. This fulfills several functions. Among them, we initially indicate that they serve as support for quilt or quilt, so these will not rest on the thumbs establishing a point of overpressure in them.

For people who are during a period of prolonged time in bed, the fin supports the weight of the own person Once the bed base and mattress are attached to a base with a conventional lifting and clamping mechanism, the fin serves as a base where the person can rest dynamic, that is, it will support totally or partially, depending on the tilt angle, the weight of the body on the plants of the feet. The inclined plane facilitates a natural exercise of the lower limbs and all anatomical mechanisms related, preventing bone and muscle conditions.

In a 45º inclined plane the vectors of strength / weight are distributed: 50% on the mattress and, somewhat less than 50% on the fin, when quantifying the coefficient of friction.

In tetraplegic patients or in a coma, the plane inclined allows you to distribute the weight between the mattress and the harp or Any conventional clamping mechanism used.

The bed base incorporates rings on both sides articulated at the height of the hands, in order to allow upper limb exercise, abdomen, pecs, etc.

The inclined plane in the bed contributes also, to a more rewarding relationship, by reducing noticeably the weight of one over the other and, the rings They provide a better grip.

The bed base flap and the side rings they may have associated conventional movement mechanisms or vibration that enhance its rehabilitative function. It will be the doctors who recommend the intensity and type of exercise to each case.

Doctors, orthopedics, ATS and therapists will be those who in the future develop a rehabilitation school. TO from now on the patient will have the option, depending on the case, of exercise. Being the best source of physical health and Psychic

Preferred Embodiment of the Invention

In view of the figures and specifically of the Figure 1 can be seen as the mattress that the invention proposes, presents a profile where along its entire surface, it is reflected in its design the respective curves that make it up, and Which are the following:

1.- head; 2.- back; 3.- waist; 4.- buttocks; 5.- thighs; 6.- corva; 7. calf; 8.-heels, which coincide with the specific anatomical form of each individual, of fixed way, or by conventional home automation elements, or they can also be made with ranges of standard measures, with certain parameters that configure the specific sizes, such as It happens in textile clothing.

In this way the mattress offers a surface contact isobaric for humans, which allows our body supports a homogeneous pressure throughout the area of contact, when in resting position, as seen in figure 2.5 eliminating the overpressure points that prevent blood circulation

The bed base and mattress incorporate a fin or footboard (10.11) at the lower end, which supports the quilt or quilt (9), avoiding that these do not rest on the thumbs establishing a pressure point, but from said fin will slide down the instep of the foot, avoiding points of overpressure in them.

The fin or footboard (10,11), allow the person perform a dynamic rest as indicated in the Figure 3. With the coupling to the bed a clamping mechanism or conventional lift, which will raise the bed to tilt that is desired. This inclination, allows to achieve a decomposition of the axes of force or pressure on the mattress and on the fin, said pressure vector of the detrimental fin increasing of the body pressure vector on the mattress as the Bed tilt angle approximates 90 degrees. He allow the body weight to load more or less on the mattress it facilitates that the person can make a gradual dynamic rest and a  natural exercise of the lower limbs and all related anatomical mechanisms, also preventing ischemia, bone or muscle conditions and facilitating the flow Natural blood circulation and fluid drainage pulmonary.

The mattress fin (10), for reasons of manufacturing, storage and transportation, will be configured by a pad attached by conventional joining mechanisms (12) as rack, sailboat, etc. The fin allows greater comfort and cushioning of the body as the body is tilted vertically bed. During the use of the bed in horizontal position the fin of the mattress prevents it from forming between the person's foot and the fin from the bed a stream of air that in winter can be annoying and harmful.

The bed base, as shown in Figure 4, it has a fin or footboard (11) at the lower end and incorporates, on both sides, rings (13) at the height of the hands, when in order to allow the integral exercise of the members upper, as well as abdominal, dorsal, pectoral, etc. The fin (11) and rings (13) may have associated mechanisms conventional motion or vibration that enhance its function Rehabilitative

The rings (13) will be articulated, in order to use them or dismiss them. Either perpendicular to the mattress to the rehabilitative functions and serve during sleep as a stop or railing protection against movements and falls. its longitudinal position to the bed base, will facilitate the attendees Perform your own functions.
