Definitions

• the present invention relates to a mattress device with modular, static or dynamic decompression.
• Such a mattress is intended to be preferably, but not exclusively, used in the hospital field in order to prevent the formation of bedsores and / or to make the user assume a particular posture, or else a succession of different particular postures.
• these mattresses include several distinct zones comprising juxtapositions of individually removable cushions which extend in a transverse direction substantially perpendicular to the general longitudinal direction of the mattress, or else parallel to said longitudinal direction.
• the cells of these mattresses are linked together and / or linked individually or in blocks, to means of inflation and pressure management through a set of pipes, so as to create a coherent whole. While it is possible to compose a custom-made mattress, according to the characteristics of the patient, before use, the presence of numerous pipes and connections makes it difficult, if not impossible, to modify the composition of the mattress after it has been put into operation.
• the object of the present invention is to remedy the aforementioned drawbacks, by proposing a modular, static or dynamic decompression mattress device which does not need to be connected to means of inflation and pressure management through pipes.
• the modular, static or dynamic decompression mattress device is characterized in that it comprises in a cover, a juxtaposition of inflatable cells, each comprising a sealed envelope, and each provided with at least two unidirectional valves at a controlled flow rate, one of which is adapted to the extraction of air while the other is adapted to the introduction of air, and in that said envelope has internally at least one block of foam or the like , capable on the one hand of being deformed under the action of pressing on said cell so as to cause deflation of said envelope, and on the other hand of resuming its shape without support so as to cause swelling of said envelope by aspiration.
• the cell When pressing on a cell, by a part of the body, the cell gradually deflates at the rate of the controlled flow rate of the extraction valve, and the foam block also crashes. When there is no longer any support, the foam block returns to its shape and, in its resumption of shape, drives the cell which re-inflates at the rate of the controlled flow rate of the introduction valve. A deflation / re-inflation of the cell is thus obtained as a function of the external stress.
• valves are positioned at one end of each cell.
• the cells have cross sections of irregular shapes.
• the cells can have, without limitation, a round, oval, square, rectangular, etc. section. This allows, for example, according to the need to position them in the mattress device, the cells on one side or another as needed, to make a protrusion or a hollow for example, and this at any time since it does not there are no pipes likely to hinder the movements of the cell.
• each envelope is closed by a sealed zip type closure.
• the envelopes which are preferably made of a nylon-type plastic material, can be closed, after introduction of the foam block (s), by a welding operation, however, a sealed zip-type closure is preferred, to allow replacement. block (s) if necessary.
• the block or blocks of foam or the like has particular reliefs on the surface, different on one side with respect to another, each dedicated to a particular function.
• one side of a cell is flat, while another, for example, is notched in the transverse direction, to create a lateral wedging.
• the cells are arranged transversely and / or longitudinally, and in an interchangeable and / or repositionable manner, as required, with the possibility of modifying its composition at any time.
• a mattress according to the invention is perfectly autonomous, it operates without a compressor, it moves on the user's own requests.
• such a mattress is not for strictly medical use, it can very well be used by individuals.
• FIG. 1 shows a schematic perspective view and: with cutaway, of a mattress device according to the invention
• FIG. 2 shows a schematic perspective view of part of the same mattress device.
• a mattress device 1 according to the invention. It comprises a removable outer cover 2 shown partially, inside which are arranged juxtaposed, inflatable cells 3.
• Each of these cells 3 comprises a sealed envelope 30, provided with two unidirectional controlled flow valves, one of which 31 is suitable for extracting air while the other 32 is suitable for the introduction of air. air.
• each envelope 30 contains a block 33 of foam or the like, with shape memory, capable on the one hand of deforming under the action of a support, and on the other hand of resuming its shape without the support. .
• the cells 3 can be of different shapes, as can be seen, without limitation, in FIG. 1, whether in the transverse and or longitudinal direction, the casing 30 being of course of suitable shape.
• the cells 3 are independent, and not connected to inflation and pressure management means, it is possible at any time to exchange one or more cells 3, whether for a replacement following a defection, or to modify the geometry of the mattress.
• FIG. 2 which represents a cell 3 seen from below, it can be seen that the casing 30 is closed by means of a closure 34 of the waterproof zip type.
