Definitions
- the present invention is related with the application of metals with biocide properties, in particular copper, in the medical industry given its antimicrobial properties.
- the present invention is related with molds for earpiece devices, which are in direct contact with the ear canal, and in which a metallic piece is inserted, preferentially having a plate shape with biocide properties, which can also be used in any earpiece device, such as earplugs for noise reduction, earplugs to avoid water entry, audio earphones, wireless technology earphones such as bluetooth technology, earplugs, earmuffs, audio protective devices, headsets, in such a manner that the device enables efficient prevention of ear diseases such as infectious external ear otitis in their users and potentially preventing other pathologies.
- Copper is a metal widely distributed in nature.
- the efficacy of the antimicrobial activity of products based in copper has motivated the development of different studies aimed to know the mechanisms involved in this activity, as well as evaluating potential industrial applications for this metal,
- earpieces such as earplugs for aquatic sports or those related to acustic trauma, audio devices and earphones in general (for example retro- auricular earpieces, intracanal earphones and completely in canal (CIC) earphones), are essential part of the devices, since the mold is the one which is adjusted to the ear of the user. For example, in the case of hypoacusia, it is required that earpiece molds are custom fabricated considering each user. Also, these earpieces allow acoustic sealing of the ear canal and acoustic modification of the aural signal.
- the following aspects must be considered: comfort degree, aesthetical appeal, operative easiness, and patient tolerance to the materials.
- Different variations can be made to the earpiece mold in order to produce a lighter, more comfortable and more suitable earpiece depending on its application.
- Even molds containing inside an aural device can be fabricated. Nevertheless, sometimes users of earpieces have allergic reactions to the material of a particular mold and the mold must be replaced by a different material.
- Otitis externa has been described as one of the complications associated to the prolonged use of earpiece devices, and particularly to the use of earphones and earplugs, since in order to avoid the feedback effect, the earpiece mold must completely seal the ear canal, which contributes to the development of a series of additional problems such as lack of air circulation, perturbation in earwax evacuation and facilitation of protective earwax being dissolved by humidity, thus making the skin of the ear canal more susceptible of infections caused by bacteria or fungus. Therefore, patients with hypoacusia are earphone users and develop otitis externa, whom while being in treatment for the infection must stop the use of the earphone, which results in deterioration of their sensorial capacity and their quality of life.
- the coating comprises an inorganic condensate modified by some organic groups on the base of coating compositions, including a hydrolyzed or a pre condensed of one or more compounds which can be hydrolyzed with at least one substituent which cannot be hydrolyzed, wherein at least one portion of the organic groups of the condensate include fluorine atoms and/or silver or copper colloids contained in the coating.
- earpiece devices comprising a metallic piece with biocide properties, preferentially made of copper, alowing to prevent in an effective way potential infections, producing a positive effect in preventing otitis externa in the user.
- These earpiece devices can be adjusted to the shape of the ear canal or to the ear shell, and the metallic piece is located inside, avoiding direct contact between the metallic piece and the skin.
- the metallic piece can be a plate and/or similar which is adjusted, from inside the mold, to the shape of the external contour of the same, covering all the zones wherein the surface of the mold is in direct contact with the skin, allowing at the same time that only said mold is in direct contact with the skin of the user.
- the described earpiece device allows solving in an effective manner the deficiencies described in the state of the art by providing earpiece devices comprising a metallic piece inside, avoiding direct contact between said metallic piece and the skin, allowing at the same time the adherence of pathogenic strains to the surface of the mold, of bacteria as well as fungus, thanks to the properties that said metallic piece provides, avoiding potential infections, and producing a positive effect in preventing otitis externa in a user.
- Figure 1 shows a scheme of a retroauricular earphone, common in the previous art, indicating the parts comprising it: mold (1 ), elbow (2) and earphone (3).
- Figure 2 shows a scheme of the retroauricular earphone mold of Figure 1 , including a metallic piece inside.
- Figure 3 shows a scheme of a retroauricular earphone mold of open mold type, known as open fit, including a metallic piece inside.
- Figure 4 shows a scheme of an earphone mold for ear shell, of full shell type, known as full shell, including a metallic plate inside.
- Figure 5 shows a scheme of an earphone mold of half shell type, including a metallic plate inside.
- Figure 6 shows a scheme of a canal type earphone, including a metallic plate inside.
- Figure 7 shows a scheme of a CIC type earphone mold, including a metallic plate inside.
- Figure 8 shows a comparison between the adherence of Stapylococcus aureus using an initial inoculum of 1 .8 x 10 3 CFU/ml, for different materials used as mold for earphones, including a copper plate inside or lacking the copper plate.
- Figure 9 shows a comparison between the adherence of Pseudomona aeruginosa ATCC 28753 using an initial inoculum of 4.2 x 10 3 CFU/ml, for different materials used as mold for earphones, including a copper plate inside or lacking the copper plate.
- Figure 10 shows a comparison between the adherence of Candida albicans ATCC 10231 using an initial inoculum of 3.6x10 3 CFU/ml, for different materials used as mold for earphones, including a copper plate inside or lacking the copper plate.
- Figure 1 1 shows a comparison between the adherence of Aspergillus niger using an initial inoculum of 9.4 x 10 4 CFU/ml, for different materials used as mold for earphones, including a copper plate inside or lacking the copper plate.
- the present invention corresponds to a mold for eapiece devices either to connect an earphone to the ear canal or to act as a cover or plug thereof, allowing to prevent in an effective manner potential infections, producing a positive effect in preventing otitis externa in a user, comprising: - a device (10) which is placed in the ear canal and or in the ear shell, adjusting its shape, and whose external border is in direct contact with the user's skin; and
- the metallic piece is adjusted from inside the mold (10) to the external contour shape thereof, allowing that only the cover of the device is in direct contact with the skin, and encompassing all the zones where contact is produced.
- Said metallic piece (1 1 ) with biocide properties can be made of copper or silver in pure state, or an alloy or combination thereof. Nevertheless, in a preferred embodiment of the invention, the metallic piece is only made of copper.
- the metallic piece is preferentially a metallic plate (1 1 ) which is placed at a distance close to the external border of the mold (10), which can be at a distance between 0.1 mm to 2 mm, it was proven that it can also be between 0.3 mm to 10 mm and has a better effect if the thickness of the copper plate is higher.
- the metallic plate (1 1 ) can have different thickness, between 0.1 mm and 3 mm.
- the material used for the fabrication of the external mold (10) is selected among acrylic, silicon or UV sensitive polymers, vinyl, polyethylene, plastics, polyurethane, elastomeric polymers, PVC, or mixtures thereof.
- the mold for earpiece devices described can use any type of external material for the fabrication of an external mold (10), as long as it complies with the functions of the mold and device previously mentioned.
- the mold for earpiece devices can be used in different types of devices, such as for example, molds for earphones as described in Figures 1 to 7, or other devices such as earplugs for aquatic sports, plugs related to acoustic trauma or audio devices in direct contact with the ear canal.
- Figure 8 and 1 1 show that the adherence of microorganisms to the mold, for different materials, after 4, 8 and 12 hours of contact between the microorganism and the mold (silicon, acrylic, and UV sensitive polymer) is strongly diminished when using a copper plate inside the mold, finding in some cases up to 100% for each of the materials tested, which without question shows the effect of inserting a copper plate inside the mold and wherein said plate is completely covered with the materials conforming said earpiece device, such as silicon, acrylic and UV sensitive polymer or mixtures of these materials.
