    [0004] Antiulceral biosanitary silicone
    [0006] OBJECT OF THE INVENTION
    [0008] The present invention refers to an antiulcer biosanitary silicone-based material for probes, masks, gloves, and other utensils that can cause friction or pressure injuries. This material has been conceived and produced to obtain numerous and notable advantages over other existing media for similar purposes.
    [0010] BACKGROUND OF THE INVENTION
    [0012] Various anti-ulcer biosanitary control materials are known for probes, masks, gloves, etc. In this sense, materials based on sterilized high-density silicone for sanitary use can be mentioned, which has elastic properties and low reactivity in tissues, which implies a slight deformation under pressure. However, these materials have various drawbacks, such as the pressure they exert on the user, which is proportional to that exerted on the user, which in the long term makes it unfeasible, since a continuous pressure on the user would end up producing a ulcer. At this point, problems can be cited for the development of an interface between the materials and the organism, given the minimal deformation of the material that undergoes pressure and the aggression suffered by the organisms' tissues when receiving this constant pressure.
    [0014] Likewise, other systems based on inflatable materials are known, into which a fluid is injected under pressure for the time required to increase the pressure of the material, moving the material towards the user. These reduce the pressure so that it only appears when it is required to compensate for some other force. Although the pressure of the tissue never completely disappears, it is changed by friction. However, the increase in costs and complexity, together with the danger of leaks from the elastic walls of the material due to the continuous deformations, does not compensate for the improvement of increasing the tolerance margin, since the underlying problem of the appearance of ulcers, which determines its economic viability, is not resolved.
    [0016] DESCRIPTION OF THE INVENTION
    [0018] The proposed anti-ulcer biosanitary silicone is intended to prevent the appearance of pressure or friction ulcers during use. For this, 3 well-differentiated components are used which, when added in different concentrations, form a single material, which in each case gives, depending on the relative concentration, the characteristic materials. The 3 components are: a sanitary grade silicone, nanoscopic graphite and micro destabilizers.
    [0020] The material of the invention presents a new strategy when creating the interface between the utensils and the tissue to avoid the appearance of ulcers: instead of creating the interface by pressure, we do it by bioadhesion, maintained by a silicone of sanitary grade in whose mesopores there are processes of variation of the hydrophobic forces with the alteration of the structure in the contact and understanding of the silicone. This material varies its properties depending on the relationship between the nanoscopic graphite and the micro destabilizer, approaching the properties of a silicone as we approach 99% of the nanoscopic graphite, while as we approach 99% of the micro destabilizer, the adherence and the interface increases but the fraction increases.
    [0022] In addition, it has been envisaged that the antiulceral biosanitary silicone can be part of a piece of silicone of sanitary range, being the orientation and size of the same the appropriate ones to maximize the effectiveness when it is incorporated in an application (probes, masks, gloves, etc. ) with the anti-ulcer biosanitary silicone remaining in contact with the tissue and the rest made up of sanitary grade silicone.
    [0024] Thus, the material with this composition ranges from anti-ulcer biosanitary silicones, which barely adhere to the tissue, to an anti-ulcer biosanitary silicone that adapts to all the irregularities of the tissue until it is completely filled. In any case, a sheet is created that adheres to the fabric by simple diffusion of moisture and without pressure.
    [0025] In any case, nanoscopic graphite is characterized by having a radius at least 4 times smaller than that of the mesopore of the sanitary-grade silicone used, with nanoscopic graphite of 250 nm in diameter being optimal.
    [0027] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0029] Currently there are very different substances with which to make the various parts of the material, and multiple techniques that we could use in adding and implanting them. However, for simple economy, we will choose generalized substances and techniques
    [0031] Thus, for a silicone of sanitary range, we will use any of those available for such use. The nanoscopic graphite will be obtained by a ball mill for colloidal grinding. The micro destabilizers will be those available for cosmetic and sanitary purposes such as Lauryl Sarcosinate.
    [0033] In the care of a patient with Duchenne-type progressive muscular dystrophy, who suffers from respiratory failure that forces him to wear non-invasive passive ventilation masks every night for 11 hours uninterrupted, to avoid the appearance of ulcers at the attachment points of the mask, we surround it at every point that comes into contact with the patient's skin, with anti-ulcer biosanitary silicone that is the subject of the invention, the composition of which, given the presence of reduced mobility and low bodybuilding, should be 40% nanoscopic graphite of 250 nm, and 60% Lauryl Sarcosinate measured by weight. This will be impregnated in the area of the sanitary grade silicone that will come into contact with the fabric, subjecting the area to ultrasonic vibrations and thermal cycles between 10 ° C and 70 ° C every 30 minutes for 24 hours. Placed over a latex mask with an adjustable strap.
    [0035] The adjustment of the mask to the patient is done by pressing the mask on the skin until the skin begins to deform, at which point it is released and the tape is adjusted 20% less.
    [0037] After progressing the degradation of the patient, and due to the lack of mobility and musculature, the mask is replaced by another whose material, also within the materials that comprise the present invention, has the following composition: 100% Lauryl Sarcosinate. This is It will impregnate the area with the sanitary grade silicone that will come into contact with the fabric, subjecting the area to ultrasonic vibrations and thermal cycles between 10 ° C and 70 ° C every 30 minutes for 24 hours. After which it will be rinsed with abundant water and 30% of 250 nm nanoscopic graphite will be applied, and 70% of Lauryl Sarcosinate measured by weight. This will be impregnated in the area of the sanitary grade silicone that will come into contact with the fabric, subjecting the area to ultrasonic vibrations and thermal cycles between 10 ° C and 70 ° C every 30 minutes for 24 hours. Placed over a latex mask with an adjustable strap. Placed over a latex mask with an adjustable strap. The adjustment of the mask to the patient is done by pressing the mask against the skin until the skin begins to deform, at which point it is held tight and released when the ventilation pump does not overcome the adherence of the material to the skin. In any case, when removing the mask, the area will be cleaned with alcohol.
    [0039] The substances used in the manufacture of antiulceral biosanitary silicone, their shapes and dimensions, and all the accessory details that may be present, shall be independent of the object of the invention, as long as they do not affect their essentiality.
