Definitions

  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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 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.
  • 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 intermediate layer thus has an absorbing effect favoring a better distribution and spreading of the moisture and therefore a better diffusion of the moisture in the interior of said chamber, the moisture being thus more quickly evacuated by the air injected inside said chamber and inducing more efficient dehumidification.
  • said first part consists of a porous or perforated substrate which is not impermeable to water and to air, said substrate being coated on at least one face with a continuous layer of watertight polymer. liquid and air water exhibiting molecular transfer properties of water vapor.
  • said second piece consists of a fabric coated on at least one of its faces with a polyurethane-type polymer layer, preferably on the outer face of the side of said physical body.
  • This property of molecular transfer of the water vapor of said polymers results from the molecular affinity inducing an attraction of the molecules of water on the molecular chains of the polymer, in particular polyurethane, comprising hydrophilic groups, said molecules of water thus being able to walk along the polymer chain and cross the layer of said polymer.
  • said second part consists of a fabric coated on at least one of its faces with a layer of polymer permeable to water vapor, that is to say having properties of molecular transfer of the vapor of water. water, preferably on the side facing the inside of said chamber.
  • said first and second parts are connected together at their peripheral edges by welding, directly with each other or via a bonding strip coated with a polymer layer, the different polymer layers of said first and second parts and said strip, if any, being weldable to each other by heat-sealing or radiation-welding, preferably high-frequency irradiation.
  • 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.
  • a peripheral bonding strip possibly folded on itself, providing the connection by welding between the two said first and second parts, said strip being itself coated on one side with less than one layer of polymer weldable with the polymer layers of both said first and second parts, the polymer layer of said strip being of the same nature impervious to liquid water, air and water vapor than that of said second piece.
  • 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 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.
  • an overpressure of the air inside said chamber is established relative to the outside of the chamber, sufficient for the air to circulate throughout the volume of the chamber.
