Definitions
- the present invention relates to a device and method for regulating the humidity on the surface of a support element of the mattress or cushion type and in the vicinity of the body of an individual resting thereon.
- This moisture can come from the body of the patient by flowing a body fluid such as by sweating, or an external source of spilled liquid. It is desirable to avoid the maceration of liquid in the soft tissues of the skin, whether it is external fluid or perspiration, because this humidification leads to a maceration which promotes the formation of bedsores and maintains infectious foci.
- a first problem of this known device is that it can not be implemented independently of the support element, in particular the mattress and that the interruption of the injection of air inside the mattress leads to make it inoperative.
- Another disadvantage of this so-called air loss mattress system is that it can lead to excessive drying of the body and requires compensation of water losses by a program of hydration of the individual.
- Dehumidification systems have been described in the vicinity of a patient consisting of a cover comprising a casing sandwiched between the patient and the mattress, said casing comprising an upper layer and a lower layer delimiting a chamber in which blood is circulated. air.
- it is sought to dehumidify the outer surface of said upper layer on which said patient rests, at least in part by transfer of water vapor by molecular migration of water molecules through the upper layer of the permeable envelope with water vapor.
- the lower layer of the envelope is impervious to air and water vapor, and the air is injected where appropriate into only a portion of the internal volume of said envelope by a plurality of injection orifices and is evacuated by a plurality of perforations which can be arranged on the sides of the upper layer.
- This dehumidification system is relatively inefficient with announced dehumidification of only 400 ml / 24h.
- the air evacuation at least partly on the patient's side resting on the device presents risks of contamination of the envelope by penetration of liquid or other contaminant coming from the outer surface of the upper layer on which the patient rests.
- the dehumidification efficiencies are either relatively low or are accompanied by dehydration of the patient resulting from the excessive airflow sent near the patient.
- the object of the present invention is to provide a new method and device for regulating the humidity on the surface or in the vicinity of the body of an individual resting on a mattress or cushion-type support element which does not have the disadvantages mentioned above. above and more efficient in terms of dehumidification efficiency.
- an object of the present invention is to provide a device and method that can be implemented independently of said support member and in particular on any type of air or foam mattress, or other, which has all the guarantees of safety in view of the risks of contamination of a fluid coming from the outside, and which does not require the implementation of a concomitant hydration of the patient.
- Another object of the present invention is to provide a device that allows automated moisture control and not just a device for only continuously decreasing moisture such as the air loss mattress devices of the prior art.
- the present invention provides a device for regulating the humidity on the surface of a support element of the mattress or cushion type and in the vicinity of the body of an individual resting thereon, comprising a casing formed by at least two parts connected together at their peripheral edges, preferably sealed by welding, defining an inner chamber, said two parts consisting of a first part intended to be disposed on the side of said body of the individual, and a second part intended to be arranged on the side of said mattress or cushion-like support element, said first part being made of a material forming a barrier impervious to air and liquid water and permeable to water vapor, said second part being constituted a material permeable to water vapor, said second part comprising at least one air injection orifice and means for evacuation of air comprising perforated or porous areas permeable to air, preferably perforations.
- said first part is non-perforated and that the air is exhausted exclusively through said second part interposed between said first part and said support member of the mattress or cushion type.
- said first piece constitutes an upper piece on which the body of the individual rests and said second piece constitutes a lower piece applied to the mattress and disposed below said first piece or upper piece.
- the said evacuation means are arranged with respect to the said injection orifice (s) so as to be able to create a circulation of the air entering into the said orifice (s). chamber through said injection port and discharged from said chamber by said evacuation means, preferably said perforations, into the entire volume of said chamber when said envelope is inflated by air injected continuously under pressure by said injection port so as to create an overpressure in said chamber.
- the air is injected at a pressure and at a rate such that the air inside the chamber is at an excess pressure relative to the air outside the chamber.
- This circulation therefore favors a decrease in hygrometry inside the envelope and maintains the transfer of water vapor from the outside of the envelope to the inside of the envelope if necessary, as long as the humidity on the outside of it is greater than the relative humidity of the air inside the envelope and therefore the humidity of the air ambient injected.
- the vapor transferred inside said chamber can evacuate outwardly despite the air circulation, allowing to maintain and promote the establishment of a high relative humidity gradient between the outside of said first piece and the interior of said chamber.
- the fact that said second part is permeable to water vapor, and that the air is discharged exclusively through said second part makes it possible to provide a dehumidification process exclusively by transfer of water vapor by molecular migration through the device and this, with a rate of water vapor transfer and therefore dehumidification higher than in the prior art, without the risk of excessive humidification below the device between said second part and the mattress, without risk of contamination by penetration of contamination or liquid from the upper outer surface of said first part since it is non-perforated, and finally, without requiring treatment of concomitant hydration of the patient as is the case when the air is evacuated from the upper layer towards or near the patient.
- the device according to the invention has higher dehumidification performance than in the patent US 5,882,349 .
- the inventors have discovered that if the lower layer is impervious to water vapor, as in US'349, a moisture saturation of the interior of the envelope is rapidly established.
- said second piece or lower layer is permeable to water vapor and the injected air circulates throughout the chamber volume, the efficiency of the water vapor transfer from the outer surface of said first piece on which the patient rests towards the outer surface of said second piece on the mattress side, is much higher.
- the air is discharged by said second piece or bottom layer, the water vapor transferred to the underside of said second piece or lower layer does not accumulate between it and the mattress on which it is arranged, and is evaporated by the exhaust air which is thus injected therein.
- the water vapor permeability of said second piece is lower than that of said first piece.
- This limited water vapor permeability of said second part makes it possible to prevent the accumulation of moisture between said second part and said support member and allows the evaporation of this humidity by the sole flow of air coming from said means. exhaust air in the absence of additional air injection between said second piece and said support member.
- said second part is substantially airtight between said injection orifice and said perforated or porous air permeable zones, the latter being disposed sufficiently far from said injection orifice so that substantially all the volume of said chamber is traversed by air flowing between said injection port and said perforated or porous areas.
- the ratio between the accumulated sections of the evacuation perforations and the section of the injection orifices is chosen so as to obtain a compromise between, on the one hand, the search for a flow rate of air circulating through the elevated chamber and on the other hand sufficient overpressure inside the chamber.
- the pressure must be sufficient to ensure that the injected air circulates throughout the volume of the chamber, that is to say that the air is uniformly distributed throughout the volume of the room. Otherwise there is a risk that the injected air is limited to circulating inside said chamber only between said injection port (s) and those of said corresponding perforated or porous localized zones. at the passage of minimal pressure drop.
- an overpressure of at least 500 Pa makes it possible to obtain a homogeneous air circulation in all directions and in particular in the zone below or in relation to the body of the patient.
- the upper limit of the air flow circulating in the chamber is related to the maximum rate of vacuum, that is to say to the cumulative section of the orifices that can tolerate the materials of said second piece of a point from the point of view of its mechanical resistance. This rate should not exceed 10% in general.
- the positive effect of the increase of the air flow on the dehumidification performance is limited by the transfer capacity of the water vapor of said first and second part layer . Beyond a certain air flow the dehumidification performance is no longer improved.
- a flow rate of 20 to 50 l / min provides sufficient dehumidification performance given the migration time of the water molecules for the transfer of water vapor through the polymer layers implemented as described below. .
- the ratio of the sum of the sections of the perforations or pores of said perforated or respectively porous zones of the evacuation of the air. relative to the sum of the sections of the injection ports is at least 2, preferably 2 to 4.
- the evaporation of the surface water on the patient's side is accompanied by a slight decrease in temperature which favors a decrease in sweating if necessary and offsets the increase in temperature resulting from the compression of the injected air. .
- the transfer of water vapor from said first piece is at least 750, preferably 750 to 2000 g. of water / m 2 / 24h, more preferably about 1000 g./m 2 / 24h and the water vapor transfer of the second part is less than 500 g. water / m 2 / 24h, preferably from 300 to 500 g of water / m 2 / 24h.
- the device according to the invention comprises a spacer part inside said chamber between said first and second parts, said intermediate part being permeable to air and water vapor.
- This intermediate layer promotes the spacing of said first and second parts and thus facilitates the circulation of air inside the chamber and therefore its better diffusion and better evacuation of water vapor.
- This insert included inside the chamber has the effect of avoiding climatic bridges between said first and second parts and to allow a better passage of air.
- said intermediate part consists of a layer of a nonwoven fibrous material, preferably polyester wadding, preferably further held in shape by a holding device, in particular a net and / or a grid of seams. quilting type.

- the different polymer layers are of the same chemical nature or chemical nature capable of making them weldable together, which is the case of polyurethane type polymers.
- Both said pieces can be coated with polymer on both sides, and be sealed to each other directly.
- the two parts are preferably for economic reasons, coated with polymer on one side only. And, if at least one of the internal faces of the two parts is not coated with polymer, especially if the first part is coated with polymer on its outer face and the second part on its inner face, the edge of one of the two parts can be folded on itself so as to have its polymer-coated side towards the inside of said chamber.

- said constituent tissues of said first and second parts are extensible fabrics in both longitudinal and transverse directions. More particularly, this property makes it possible to promote a better distribution of the weight of the body, that is to say on its larger surface area, and that the tissue conforms to the shape of the body and does not generate localized points of excessive compression of the body. can generate blockages of vascularization and pathologies that result.
- said air evacuation perforations are disposed on the periphery of said second piece. These peripheral zones do not coincide with the central zone of the envelope on which the body is normally supported, but surround it, thus facilitating the evacuation of air by said perforations.
- said second piece is of substantially rectangular shape and the device comprises a single injection orifice near the middle of a longitudinal edge of said second piece, said air evacuation perforations being disposed at proximity of the lateral edges and the longitudinal edge opposite that of the injection port.
- the injection orifice is disposed relative to said evacuation perforations so as to circulate the air throughout the inner chamber of the casing and to evacuate to the outside as quickly as possible the moisture transferred. from the vicinity or the surface of the body towards the interior of said chamber.
