DESCRIPTION:
BRIEF SUMMARY
The present invention relates to removal of dust particles produced by the treating of human or animal nails.
INTRODUCTION
A common foot related problem requiring treatment by a chiropodist is thickened nails. One method of treating this condition is to remove a part of the nail using a grinding wheel. Chiropodists often have to visit the homes of patients to perform this treatment as it might be too painful for the patient to walk to a surgery. This means that the chiropodist must carry equipment with them to the patient's home.
A considerable amount of dust is produced whilst performing the nail grinding. For hygiene purposes the resulting dust needs to be cleaned. This can be difficult if the treatment is not performed at the surgery, for example the dust might need to be removed from a carpet on the floor of a patient's home. A potentially more serious problem is the very fine dust particles which are produced by grinding nails. Dust particles of up to 12.0 microns in size can penetrate the respiratory tract. This can cause lung problems, particularly for a chiropodist, who is exposed to such particles frequently over a long period of time. People with respiratory problems are also especially prone to these undesirable effects.
The wearing of a surgical mask will help prevent the inhalation of dust particles. However, it is more effective to prevent dust particles from entering the surrounding air. Known dust extraction devices for use in the treatment of nails rely on suction to extract dust particles. These techniques are not very effective for dealing with very fine dust particles. The suction device has to be positioned very close to the nail being treated in order to remove particles effectively. This requirement can restrict the chiropodist's workspace for performing the grinding and also means that the patient may have to move their foot several times during the treatment. The resulting apparatus may also be large and heavy and therefore not feasible for carrying for use during home visits. Some grinding wheels are fitted with dust extraction systems, but these are expensive and again rely on suction so they do not effectively deal with very small dust particles.
It is an object of the present invention to provide a relatively low cost portable device which can extract very small dust particles from the air whist overcoming the limitation of having to position a suction device directly by the nails being treated.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention there is provided an apparatus for extracting particles produced by the treating of human or animal nails, comprising: support means; means for generating an air current; and dust extraction means, wherein said support means is positioned between said air current generating means and said dust extraction means.
According to a second aspect of the invention there is provided a method for removing dust by treating nails comprising steps of: dust enters the dust extraction means.
According to a third aspect of the present invention there is provided a kit of parts for use in treating nails, comprising: animal nails.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 illustrates an embodiment of the particle extraction device in use;
FIG. 2 illustrates a cross-section through the particle extraction device identified in FIG. 1; and
FIG. 3 illustrates an exploded respective view of the particle extraction device shown in FIGS. 1 and 2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The invention will now be described by way of example only with reference to the previously identified drawings.
FIG. 1 illustrates a chiropodist 101 performing nail grinding treatment on a patient. The patient's foot 102 is shown resting on an embodiment of the present invention, portable device 103. The chiropodist uses a grinding wheel tool 104 to perform the treatment. Dust produced by using the grinding wheels on the patient's nails is intended to be removed from the surrounding air by the device 103.
It is the inventor's inten
