Description:
BACKGROUND OF THE INVENTION
The invention relates to a tool for the care and sanitation of the cavities of the body and more specifically but not exclusively to a type of tool commonly called a swab. It is sometimes used to cleanse the mucosities of the nose but especially to extract ear wax.
Ear wax is secreted by the sebaceous glands of the skin's external auditory duct which allows this duct to be lubricated and prevents dust and small solid bodies from getting in. Unfortunately, if this substance accumulates it can cause ear singing and some deafness.
At first, ear swabs were used to extract the cerumen, but as these little instruments were made of horn, bone or ivory they could damage the ear duct.
Therefore, they were quickly replaced by a flexible swab fitted with cotton on at least one of its ends. This provided a cushion which prevented wounding the ear duct, while it furthermore enabled it to absorb some of the substance to be extracted. Unfortunately, the absorption capabilities of this heavy and thick padding are small. Further, while the swab stick is being inserted, it is inconvenient and awkward as it packs down a sizeable amount of the cerumen at the bottom of the auditory duct which could bring about the troubles previously mentioned.
A result provided by the present invention is that a tool of this nature will not push down the substance to be extracted to the bottom of the cavity, while allowing a sizeable amount of this substance to be removed.
To this end, the invention provides a tool such as the one aforementioned, however, deferring in that the padding (cotten) absorbing part which is made up of several flexible laminations.
BRIEF SUMMARY OF THE INVENTION
A swab for use in body cavities has a body mounted on a stick. The body is a body of revolution around the axis of the stick with a hemispherical top and a truncated cone base. Padding covers or forms the body and is a plurality of spaced flexible laminations fixed to the body. The laminations may have a slight helical curvature in the same direction about the body around the axis of the stick.
REFERENCE TO THE APPENDED DRAWINGS
The invention will with reference to a preferred embodiment now be described as a non-restrictive example, as shown in the accompanying drawings in which:
FIG. 1 is a face view of the instrument; and
FIG. 2 is a sectional view on the line II -- II of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Following the swab stick example, the tool according to the invention as shown in FIGS. 1 and 2 is comprised of a stick 1, with at least one padding at its end which has a shape circumscribed by a revolving area around axis 3 of stick 1, having a hemispherical portion 4 with a diameter D, connected to a major base area in the shape of a truncated cone 5.
According to the invention's main characteristic, the padding 2 is made up of several flexible laminations 6, which are connected to the stick 1 by one of their edges 7.
Preferably, the laminations 6 presents a slight helical curvature about the body around the axis of the stick instead of being on a plane and are radially set, at least locally. As the laminations 6 are all curved in the same way, when the padding is inserted in the ear duct, it will create, according to the direction of rotation of the stick 1 variations of diameter D. This, on the one hand, can be decreased for an opposite rotation to the direction of arrow F, in order to facilitate insertion of the padded area, for example, or it can be increased by rotation in the direction of arrow F in order to accentuate the pressure on the duct's wall by the external range of laminations 6. In order to improve the drawing of the substance to be extracted from the wall of the duct, it is useful to turn down the tips 8 of the laminations, in a rounded fashion or at an angle as at 9, against the adjacent area of the body, placing these extremities substantially tangent to said wall and thus to the area circumscribing the shape of the padding 2.
In order not to limit the amount of substance to be extracted by this instrument, to the specific space volume 10 between the laminations 6, laminations are set helically (FIG. 4) in such a manner that they will move the product to be extracted toward the outside of the duct.
The set of laminations 6 can be molded into one piece with the stick 1, or with a cylinder liner 11 which will cover the tip of a separate stick.
The padding 2 will be advantageously manufactured in rubber or plastic.
This tool will be very useful in taking cerumen out of the auditory duct.
The flexible laminations 6 in fact, do not run the risk of injuring the wall of the duct; the cerumen will not be packed down at the bottom of the duct as it enters the laminations 6; there is no limit to the quantity of cerumen that can be extracted in one operation; and it can be used in ducts with very different diameters.
Moreover, this instrument is not limited to the extraction of harmful substances, it can also be used for the deposit of pasty or liquid substances in great quantities, which will have been previously inserted between the laminations. If the padding is dipped in a container for example, deposit can be made by rotating the padding in the opposite direction to arrow F, causing a decrease in volume between the laminations, and thus the removal of the substance from the padding which will evenly apply itself on the wall of the duct.
