Method and Article for Removing Splinters with a Disposable Lancet

Abstract

A method and article for removing splinters is provided. First a generally flat lancet is removed from its packaging. The disposable lancet is then used to pierce the patients skin and loosening the skin in the area adjacent to the splinter before tearing the skins with a sharp point of the lancet. Then the lancet is bent at bend line located at center between both end points till the points of each end are parallel and aligned so their able grasp objects between the points. The lancet should look and function more so like tweezers after the previous step. The foreign object can now be removed, thereafter the lancet, packaging and splinter is now disposed of.

DETAILED DESCRIPTION OF THE INVENTION

[0040] Referring now in detail to the drawings and, in particular to FIGS. 6-17, there is illustrated a disposable lancet 10, according to the present invention. This type of lancet is preferred for use in the method embodying the present invention, for removing foreign objects from skin. The lancet is made from, for example, corrosion resistant stainless steel. The lancet has a handle area 12 and 24 with raised embossed knurls 13 with kurf cut line 20 and points 14 and 22. A pre-sterilized lancet would be removed from its individual packet and used to prick the finger of the person whose blood needs testing or to remove splinters. The lancet would then be discarded.

[0041] It was surprisingly found that although this type of lancet has been used for years to draw blood and remove splinters, it has never been designed to be utilized for splinter or other foreign object removal, while its flat surface and blade or opposing blades are ideal for this purpose. The disposable lancet 10 ideally is packaged in an individual pre-sterilized packet. The packets could be sold, for example, in a small container with ten or twenty disposable lancets. The lancet is removed from the packet and held by handle areas 12 and 24 which may be provided with raised embossed knurls 13 of any desired design which will aid in gripping and also add to the rigidity of the lancet.

[0042] An effective lancet according to the invention will have the following general dimensions: the flat point can range in length from 2/64 to 5/16; the overall length can range from 0.75to 5; the width can range from to ; and the thickness of the lancet, excluding any raised gripping portions, can range from 0.003 to 0.015.

[0043] The following dimensions are set forth as the preferred dimensions for one type of lancet (as shown in the drawings), but they are not intended to limit the invention. The lancet ideally has a length of 3 5/16 1/16, inclusive of the point. The width is approximately 15/64 and the height 0.007 non-inclusive of the raised knurls. The total height including the raised knurls would be in the range of 0.025-0.032.

[0044] A single row of knurls lies in the center of the handle area and is approximately 0.07 wide and extends 5/16 along both lengths except where the kurf cut line is. Each knurl has an area of 1/16 by 1/16.

[0045] The length of the point is 7/64 1/64. The point, as stated above, is in the shape of intersecting flat planes. The planes should be offset with regard to each other 253. In the event that a long point is desired, its point length would be 5/32 1/64.

[0046] Returning now to a description of the method, the sterilized lancet would be removed from its package and the user, grasping the handle areas 12 an 24 of lancet 10 can be used to loosen the skin around the splinter or foreign object 16. By piercing the skin adjacent to the foreign object and then lifting the lancet 10 in a direction perpendicular to the entry direction, the flat blades 17 and 18 can easily tear the patient's skin in directions B and C in FIG. 10. This can open the area adjacent to the foreign object or directly above it and thereby loosen it. Such a tearing action, by a needle or pin perpendicular to the direction of entrance of the needle or pin is not as effective due to its shape. Skin and foreign objects will tend to easily slide off the tapering polished conical point of a needle or pin instead of tearing the skin, as with a flat point.

[0047] Once the skin surrounding the foreign object has been loosened up, FIG. 11. Shows the lancet being folded by the user applying sufficient pressure on the handles (in the direction of arrow D and E). FIG. 12-17 lancet 10 is showing a folded lancet at the kurf cut line 20 till points 22 and 14 are parallel.

[0048] The folded lancet 10 in FIG. 17 can now be grasped somewhat with a tweezer-like grip, would manipulate the lancet so that the points 14 and 22 is brought toward the skin area 15 containing the foreign object, as shown in FIG. 17, in the direction of arrow A. The user then applies sufficient pressure on the handles (in the direction of arrow D and E) such that point 14 or 22 then pierces the skin just under and over the foreign object 16. Since point 14 or 22 is a flat surface, when the gripped splinter is manipulated in an upward direction away from the skin (shown by the direction of arrow F) it can actually pull out the foreign object. A single point or pin cannot easily pull an object out because it has a single area and the object will tend to slide off the point.

[0049] In this regard, the lancet can also be manipulated to pierce the skin, adjacent and parallel to the splinter, in the direction of arrow A. The rear end of handle area 12 and 24 can then be pivoted downwardly away from the splinter (as shown by direction F), causing points 14 and 22 to move into or over and under the splinter. Removal of the lancet at this point makes it highly likely that the splinter can be dislodged.

[0050] Thus, while only one embodiment of the present invention has been shown and described, it is to be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention as defined in the appended
