Definitions
- the present invention relates to a brush for medical and pharmaceutical use.
- it relates to an improved brush which can be used in all those applications - for example for pap test (Papanicolaou's test) samples in the health sector - where softness is a fundamental requirement.
- the brushes manufactured hitherto consist of “bristles” formed by monofilaments of synthetic material which are mounted, in a substantially radial arrangement, on a shank made of plastic or metallic material.
- bristles is used in a conventional manner to indicate not only bristles of animal origin, but any other natural or synthetic strand-like element, both in the form of monofilaments of the known art and in the form of the filament yarns according to the invention.
- Italian Patent No. 1147406 describes a brush for medical use, in particular for use in the oral cavity, in which the metal shank is coated with an insulating and soft plastic material so as not to create galvanic currents in contact with the dental prostheses and so as not to damage the gums.
- European Patent Application EP-A-0250680 discloses a brush for cosmetic use in which the bristles have a cross-sectional shape particularly suitable for retaining the cosmetic products to be applied.
- the brush bristles with a greater degree of softness by using suitable materials and/or reducing the thickness of the monofilaments and/or distributing the latter in particular geometrical arrangements.
- the impossibility of obtaining diameters of less than 0,05 mm does not allow to obtain the desired softness, in particular when the length of the bristles is fairly short, since the bristles inevitably retain a certain rigidity.
- the object of the present invention is that of solving the abovementioned problems by providing a brush with a high degree of softness also when it has a small overall diameter.
- a brush intended in particular for medical or pharmaceutical use, but certainly applicable also in the cosmetics sector, of the general type described above, comprising a plurality of bristles which are mounted on a mounting support consisting of a double spirally twisted wire and having the characteristic features indicated in Claim 1.
- a brush 1 is comprised of a support formed by a pair of interwoven semi-rigid wires - preferably metal wires lined with plastic material - one part of which performs the simple function of a gripping shank 2, while another part performs the function of a mounting support 3 on which a plurality of bristles 4 are mounted.
- the present invention teaches to use bristles 4 which have cross-sectional dimensions which are noticeably smaller than those of the bristles used hitherto by the known art; for this purpose the bristles 4 consist of filament yarns, for example formed by natural textile fibres, such as cotton fibres, or preferably fibres obtained from polymeric material extruded and stretched until fibres with dimensions of the order of magnitude of the polymeric chains are obtained.
- the filament yarns according to the invention therefore have dimensions which are noticeably smaller than 0,05 mm (2 mils) and preferably less than 0,01 mm.
- polyamide filament yarns they preferably have a count of the order of 0,6 to 0,7 tex (the unit of measurement of 1 tex corresponds to a yarn having a weight of 1 g per 1000 m of length), which means a size about a tenth of that of a polyamide monofilament having a diameter of 0,05 mm.
- filament yarns made of polyester or polyamide, for example PA6.6 and PA6, extruded at temperatures of between 200°C and 270°C, preferably between 215°C and 262°C, and greatly stretched, so as to cause orientation of the molecules, in a nitrogen atmosphere are particularly advantageous.
- these filament yarns are very difficult to handle, at least from the point of view of mounting on the mounting support 3.
- the monofilaments were cut from monofilament bars of reasonable length (about 1 m), without this creating any particular problems, this operation is no longer possible for filament yarns, which would not have enough consistence to be gripped and cut.
- the wire of the mounting support 3 may be made of stainless steel or metal coated with suitable plastic materials such as, for example, polyurethane. In this way it is possible to achieve the desired degree of hygiene for the brush as a whole.
- the brush according to the invention has a softness of the brush plume which is without comparison, even in critical conditions, i.e. for overall diameters D which are slightly greater than the diameter d of the mounting support 3, while still being able to perform the right mechanical action during frictional contact, so as to remove or distribute effectively the desired substances, without damaging the contact surfaces.
- Said brush is therefore excellently suited especially for all those cases mentioned in the introduction, where the frictional contact occurs in the vicinity of delicate organs and tissues of the human body.
- the shapes of the brush may be many and also very different from that described, without thereby departing from the protective scope of the present invention, as defined by the following claims.
- the medical and pharmaceutical fields have been indicated as the preferred fields of use for the brush according to the invention, it is also certainly possible to contemplate its use in the cosmetics sector.
