(45) Although the skin tag removing device shown in
(46)
(47) Two opposite flexible pressure members, a first pressure member 3 and a second pressure member 4, extend towards each other from the ring-shaped base member 2 along the major axis X.
(48) Each pressure member 3,4 consist of two V-shaped pressure member parts 3a,3b and 4a,4b. Each respective V-shaped pressure member part 3a,3b;4a,4b has a first end of a respective first leg 3a,3b;4a4b secured to the edge 5 of the ring-shaped base member 2 along the interior diameter of said ring-shaped base member 2 so that opposite apices of the two sets of respective V-shaped pressure member parts 3a,3b and 4a,4b face each other. The second legs 3a,3b and 4a 4b have respective second ends secured to elongate occlusion member 6 and 7, respectively, at a distance from each other about the minor axis Y. This distance is defined amongst other by the angle of the apex of the V-shaped pressure member part 3a,3b;4a,4b, the lengths of the first legs 3a,3b;4a4b, the lengths of the second legs 3a,3b;4a4b, and by the securing point of the ends of the legs to the edge 5 of the ring-shaped base member 2. The distance is further defined by the size of a central opening 10 of the ring-shaped base member 2, which ring-shaped base member 2 is sized to provide space for both pressure members 3,4 and occlusion members 6,7, and to allow the pivoting of same together.
(49) The pressure members 3,4 are highly flexible and have an in-build memory making them able always to aim for returning to the most relaxed position close to the plane of the ring-shaped base member 2 after having been pivoted from the position seen in
(50) Each of the views of
(51) The elongated occlusion members 6,7 that are facing each other are substantially parallel with the minor axis Y. They are also longer than the interior minor diameter of the central opening 10 of the ring-shaped base member 2. The aperture 9 for inserting the skin tag to be removed is, in the ready-to-use condition, delimited by opposite occlusion members 6,7 and opposite sections or lengths of the perimeter of the edge 5 of the ring-shaped base member 2.
(52) In the ready-to-use condition the flexible pressure members 3,4 and their associated occlusion members 6,7, are deflected slightly out of the plane of the ring-shaped base member 2 whereto their first legs 3a,3b;4a4b are secured to arrange the occlusion members 6,7 below said plane. The lengths of the occlusion members 6,7 are selected so that opposite free ends 11a,11b;12a,12b of each occlusion member 6,7 can be engaged at the underside 8 of the ring-shaped base member 2, thus at the skin-facing side. The occlusion members 6,7 become more or less pre-tensioned by being pivoted from the condition seen in
(53) The more the occlusion members 6,7 subsequently are spread apart, e.g. when a component is inserted in the aperture 9 between the occlusion members so that the pressure members 3,4 are brought to pivot even further away from the straight-from-the mold condition, the higher tension of the pressure members 3,4. The pressure members 3,4 will now act as opposite spring members to return the occlusion members 6,7 to the most relaxed condition in the current situation whenever possible. In the ready-to-use condition the free ends 11a,12a;11b,12b of an occlusion member 6,7 engage the underside of the ring-shaped base member 2. The pivoting of the pressure members 3,4 accumulates energy that makes the pressure members 3,4 to return the occlusion members 6,7 towards the skin-facing underside of the base member 2.
(54) When the skin tag removing device 1 of the first embodiment seen in e.g.
(55) The angle of the pressure members 3,4 in relation to the plane of the base member before tensioning, thus as seen in
(56) The design of the pressure members 6,7, having V-shaped opposite pressure members parts 3a,3b;4a,4b gives a pressure member 3,4 excellent spring properties. The V-shaped design is preferred although variants are within the scope of the present invention. For example the pressure members can simply be a spring member shaped as fingers spread as a fan, which fingers are secured to both the ring-shaped base member 2 and to an occlusion member 6,7. Yet an alternative design of a pressure member is a flap fitting inside the central opening 10 of the ring-shaped base member 2 and being hinged to the edge 5 of the ring-shaped base member 2 and having a free end provided with the elongate occlusion member 6,7.
(57) The opposite elongate occlusion members 6,7 can be spaced apart to enlarge the aperture 9 so that the skin tag removing device 1 can pass over a skin tag, as illustrated in e.g. the subsequent
(58) The oblong appearance of the ring-shaped base member 2 is very user-friendly. The user tends to grasp an object the easiest way, which will be where the object provides most and best space for operating it. In the present case this is along the major axis but in case of a circular skin tag removing device the aperture provides inherent instructions for grasping.
(59)
(60) The first embodiment of the applicator rod 13 has an operating end 14 facing opposite a housing 15 and against an applicator end 16. The applicator end 16 has a bifurcated applicator head 17 that tapers towards a free tip 18. The bifurcated applicator head 17 is divided in opposite legs 19a,19b between which a space 20 sized and dimensioned for surrounding a skin tag (not shown) is delimited. The tapering of the applicator head 17 serves to facilitate inserting the applicator head 17 into the aperture 9 of the skin tag removing device 1. Opposite the applicator head 17 the operating end 14 is provided with an enlarged finger press button 21.
(61)
(62)
(63) The second embodiment of the applicator rod 28 corresponds substantially to the first embodiment 13 and for like parts same reference numerals are used. The second embodiment 28 differs from the first embodiment 13 in that the applicator rod 28 has a first guide groove 29 along at least a part of its length. The first guide groove 29 can be provided on just one longitudinal side or on both longitudinal sides, along the entire length or just on a part of the length. The first guide groove 29 gives the applicator rod 13a U-shaped or I-shaped cross-section.
(64) For optimum fit and sliding into the guideway 23 of the housing said guideway 23 should the best have a corresponding cross-section sized to reciprocate the applicator rod 13;28.
(65) The applicator rod has a second stopper 30 in form of an axially extending leaf spring 30 that can flex into an axially extending recess 31 of the applicator rod 28. Said applicator rod 28 reciprocates inside a guideway 23 of a second embodiment of a housing 22 seen in longitudinal section in
(66) The second embodiment of a housing 22 has an exterior appearance similar to the first embodiment of a housing 15 seen in
(67) The second embodiment of a housing 22 further has a first stopper 33 in form of a breast 34 that catches the second stopper 30, the leaf spring, when the applicator head 17 is returning towards the inlet 24 of the guideway 23, thereby preventing separation of applicator rod 28 and housing 22. Thus the second embodiment of an applicator rod 28 cannot be pulled out of the second embodiment of the housing 22.
(68) The exterior surface of the applicator head 17 has ridges 32 to improve engagement with the opposite occlusion members 6,7 of a skin tag removing device 1.
(69)
(70) The holes 38 are rectangular so that the first embodiment of a skin tag removing devices 1 rests on the mounting surface of the top wall 37 with the opposite occlusion members 6,7, free to pass through the holes 38, as seen better in the enlarged scale view of
(71) A skin tag removing device of the present invention may advantageously have an adhesive (not shown) at the underside, the skin-contacting surface, opposite the topside, which adhesive can be utilized to both secure the correct position of the skin tag removing device 1 in relation to the hole 38, and to secure the skin tag removing device on the skin around the skin tag after completed application and mounting of the skin tag removing device.
(72) The box 36 has a circumferential wall 41, the height of which defines the depth of the free space 40 below the top wall 37. The circumferential wall 41, and thus the box 36, may advantageously be placed on a support face (not shown). To facilitate removal of an adhering skin tag removing device 1 from the box 36 the top wall 41 may expediently have a first release liner at the area in contact with the skin tag removing device to provide for easy detachment and release of the skin tag removing device.
(73) A skin tag removing device may be provided with a detachable adhesive cover (not shown) when positioned on the box 1. The detachable cover can utilize the same release liner or another release liner for said cover to provide easy access for the applicator. The same cover can be reused to cover and enclose the skin tag once the skin tag removing device has been mounted on the skin tag.
(74) The adhesive and/or the cover is a further means to prevent the correctly mounted skin tag removing device from entangling or being caught by exterior items, such as e.g. the clothes. The adhesive on the underside and/or covers may then also serve to prevent accidental non-timely tearing-off of the skin tag removing device.
(75)
(76) In
(77) The second embodiment of housing 22 is in its position farthest from the applicator head 17 and abut the finger pressing button 21, this way exposing the applicator end 16 and the ridges 32 to be free to be inserted into the aperture 9 of the first embodiment of the skin tag removing device 1 in the step of operating the applicator system of the present invention, as shown in
(78) In the position shown in
(79) In the enlarged scale view of
(80) As seen in
(81) Then, the second embodiment of housing 22 is simply moved towards base member 2 of the skin tag removing device whereby the outlet flange 27 is expediently used to move the first embodiment of a skin tag removing device 1 in front of said outlet flange 27 thereby pushing the first embodiment of a skin tag removing device 1 towards the tip 18 of the applicator rod 28, which is resting on the skin surface 43, wherefrom the skin tag 42 protrudes. When the first embodiment of a skin tag removing device 1 reaches the skin surface 43, the first embodiment of a skin tag removing device 1 disengages the applicator head 17 and occludes with the occlusion members 6,7 around the skin tag 42, as seen in
(82) The skin tag removing device described above in relation to
(83)
(84) The pressure members 34 are flexible rods spanning the central opening 10 of the square base members 2 by having one end secured at a corner of the square base member 2 at the edge 5, and having an opposite end secured to the end of an associated elongate occlusion member 6,7 that diverges at an angle from said corner towards the subtending side of the base member 2 to define the aperture 9 for receiving a skin tag in the operative condition, similarly as described above in relation to
(85) A third embodiment of a skin tag removing device 1 is shown in
(86) The modified skin tag removing device 1 corresponds substantially to the skin tag removing device 1 shown in
(87) The modified skin tag removing device 1 of the third embodiment differs from the first embodiment of a skin tag removing device 1 in that the reinforcing members 6a,7a of the respective occlusion member 6,7 are shorter, to provide space for two opposite guide beads or guide keys 46a,46b that protrude towards each other inside the central opening 10 from the interior diameter of the ring-shaped base member 2 above the aperture 9.
(88) The modified skin tag removing device 1 is to be used in a modified applicator system utilising a third embodiment of an applicator rod 47 in form of the modified applicator rod shown in
(89) Just as the second embodiment of an applicator rod 28 the third embodiment of an applicator rod 47 has opposite first guide grooves 29a,29b along its length, or along at least a part of its length, and ridges 32 on the exterior surface of the modified applicator head 17 on respective opposite sides of the first guide grooves 29a,29b, which ridges 32 serve to engage the opposite occlusion members 6,7 of e.g. the third embodiment of a skin tag removing device 1 shown in
(90) The modified applicator rod 47 thus is a third embodiment of an applicator rod, which differs a.o. from the second embodiment of an applicator rod 28 in that the respective opposite legs 19a,19b of the applicator head 17 has respective tapered free tips 18a,18b as in the first embodiment of an applicator rod 13 instead of rounded as in the second embodiment of an applicator rod 28 to better penetrate the aperture 9 of any of the embodiments of skin tag removing device 1,1,1 and open the occlusion members 6,7 for receiving the skin tag.
(91) The opposite exterior free faces 48a,48b of the legs 19a,19b of the applicator head 17, thus exterior to the space 20, is provided with second guide grooves 49a,49b inside which the guide beads or guide keys 46a,46b of the third embodiment of the skin tag removing device 1 runs when the applicator head 17 is inserted through the aperture 9 of the third embodiment of said skin tag removing device 1. The guide beads or guide keys 46a,46b serve for improved control and guidance of the position and orientation of the third embodiment of the skin tag removing device 1 both when being mounted on the applicator head 17, along the method steps shown in
(92)
(93) The side view of
(94)
(95) Thus the mounting method is not dependent on how the applicator head 17 is turned in relation to which guide key 46a,46b that face which shoulder 54a,54b. For example can the first guide face any of the first or second shoulder during inserting the applicator head 17 into the aperture 9 to spread the occlusion members 6,7 apart.
(96) In the present third embodiment of an applicator rod 47 the first shoulder 54a and the second shoulder 54b are offset lengthwise along the longitudinal axis of the third embodiment of the applicator rod 47 so that axial disengagement of guide keys 46a,46b and co-operative shoulders 54a,54b on opposite sides of the aperture 9 takes place at different point of time during a releasing step from a modified holder component 35, in which releasing step the third embodiment of a skin tag removing device 1 is gradually set free from said modified holder component 35 when the applicator head 17 with engaged third embodiment of a skin tag removing device 1 is moved upwards and away from said modified holder component 35 and out of the hole 38, as described below in connection with
(97) Emphasis is made that neither shoulders nor offset shoulders are mandatory. Accordingly, both shoulders 54a,54b can be provided in the same section of the respective second guide grooves 49a,49b, be provided at different sections or even be avoided. The axial distance between the shoulders 54a,54b influences on when the third embodiment of the skin tag removing device 1 is allowed to slide axially on the applicator head 17, and to which extent in response to a force directed away from the modified holder component 35, including when the adhesive force between modified holder component 35 and the adhesive skin-facing side of the third embodiment of the skin tag removing device 35, which skin-facing side is also the modified holder component facing side, is overcomed or is being overcomed.
(98) The sliding engagement between guide keys 46a,46b and cooperative shoulders 54a,54b serve as a means to keep the third embodiment of the skin tag removing device 1 on the applicator head 17 when the skin tag removing device 1 is lifted free of its adhesive attachment to the modified holder component 35, e.g. any of the boxes 36,36, and to control this detachment and ensure that detachment is conducted smoothly and easily. In particular for the offset shoulders 54a,54b provided in the exemplary embodiment in relation to
(99) Thus detachment of the third embodiment of a skin tag removing device 1 from the modified holder component 35 may take place earlier at the first shoulder 54a at the first blind proximal elongate guide groove section 53aof the first second guide groove 49a than at the second shoulder 54b in the second intermediate guide groove section 52b of the second guide groove 49b.
(100) The suitable adhesive for the present invention provides an adhesive force selected to attach the skin tag removing device 1,1,1 firmly with the aperture 9 above the hole 38 of the modified holder component 35 so that the skin tag removing device 1 does not accidentally dislocate when the applicator head 17 passes through the aperture 9 to open the occlusion members 6,7. The adhesive force is however not stronger than the skin tag removing device easily detaches from the modified holder component 35 when the skin tag removing device is retracted as being mounted on the applicator head. A beneficial adhesive is of the kind that has good storage time, does not dry out fast and is easy releasable from a potential protective release liner.
(101) An adhesive configuration of the third embodiment of a skin tag removing device 1 is shown in
(102) Emphasis is made that an adhesive skin tag removing unit 55 of the present invention may include any of the embodiments of skin tag removing devices 1,1,1 of the present invention and be used with the applicable applicator rod and applicator housing. Shapes, dimensions and thicknesses are only examples and the individual components of an adhesive skin tag removing unit can be given any design that complies with the chosen design of the associated skin tag removing device and does not obstruct and/or complicate the application and use of the skin tag removing device itself in general. Such design confers the beneficial properties to the adhesive skin tag removing unit that it is easy to detach from the modified holder component without the skin tag removing device accidentally gets off the applicator head due to too strong adhesive attachment force between skin tag removing device 1,1,1 and holder component when the skin tag removing device 1,1,1 is to be detached from its adhesive attachment to said holder component.
(103) The adhesive skin tag removing unit 55 used with the skin tag removing device 1,1,1 includes a second release liner 56, a cover 57, and an adhesive layer 58 having adhesive on both sides, e.g. a piece of double-coated tape. In the alternative the skin tag removing device 1,1,1 can be coated with the adhesive where appropriate, such as on at least a part of the skin-contacting side. For the present exemplary embodiment the figure-of-eight-shaped second release liner 56 has a large diameter part 59 to protect a skin adhesive 60 on a skin-contacting surface 61 of the cover 57, and a substantially smaller diameter part 62 comprising a ring-shaped release part 65 around a central release part 66. The ring-shaped release part 65 covers the perimeter 63 of a double-coated adhesive layer 58 and the central release part 66 covers the area bordered by the ring-shaped release part 65.
(104) The adhesive layer 58 has a traverse slot 64 aligned with, or alignable with, and optionally superjacent the aperture 9 of the skin tag removing device 1,1,1. In the present exemplary embodiment the traverse slot 64 is an I-slot, so that the opposite flaps 67a,67b better can open together with the occlusion members 6,7 when the applicator head 17,17 passes through. The area and outline of the double-adhesive layer 58 may expediently be a bit greater than the area and outline of the skin tag removing device 1,1,1 so that the double-adhesive layer 58 provides a smooth protective outer edge 68 beyond the outer perimeter of the base member 2 of the skin tag removing device 1,1,1, and thereby in an easy manner serve to avoid that the skin tag removing device 1,1,1 injures the skin around the skin tag at the site of application of said skin tag removing device 1,1,1, thereby avoiding or at least reducing incidents of a.o. galling, pruritus and redness that could obstruct treatment time.
(105) The ring-shaped release part 65 of the second release liner 56 has a projecting lip or flap 69 to facilitate removal of said second release liner 56.
(106) In the exploded view of
(107)
(108) Use of the adhesive skin tag removing unit 55, including how the applicator system is used for application of the skin tag removing device 1,1,1 on a skin tag 42, and how the adhesive skin tag removing unit 55 is utilised for mounting a skin tag removing device 1,1,1 of the present invention in a constrictive, compressing arrangement around the skin tag 42 to be removed, is described with reference to
(109) Accordingly
(110)
(111) In the perspective fragmentary view of
(112) Now,
(113)
(114) As shown in
(115) In the situation seen in
(116) The gap between the flexible release structure parts 72a,72b of the flexible release structure 71 is aligned and substantially parallel with the aperture 9 between the occlusions members 6,7 of the third embodiment of a skin tag removing device 1 on the skin tag removing unit 55.
(117) When the pressure from the applicator 22,47 continues in the direction A the third embodiment of a skin tag removing device 1 comes slightly along and is moved more or less inside the hole 38 depending on the applied downwards force and the size of the hole in relation to the outline of the skin tag removing device, as seen in
(118) The opposite section 58a,58b of adhesive layer 58 around the I-slot stick to the occlusion members 6,7 and are pulled into the hole 38 adhered to said occlusion members. In the figures the adhesive layer is shown as being transparent but this is not mandatory.
(119) In the first release step shown in
(120) When overcoming the adhesive force between the adhesive layer 58 and the flexible release structure 71 upon pulling the applicator 17,22 free of the hole 38 again, the third embodiment of a skin tag removing device 1 can, due to the presence of shoulders 54a,54b of the opposite guide groove 49a,49b, inside which the guide keys 46a,46b of the third embodiment of a skin tag removing device 1 runs, travel a little along the longitudinal applicator axis whereby the third embodiment of a skin tag removing device 1 can become spaced from said outlet flange, e.g. be spaced from said outlet flange a distance corresponding to the distance between the shoulders 54a, 54b.
(121) In
(122) In the mounting step of the situation of
(123)
(124)
(125) The flexible release structure 71 allows a smooth and gradual detaching of the skin tag removing unit 55 and associated skin tag removing device 1,1,1 from the modified holder component 35, as shown in the subsequent figures. In particular the flexible release structure 71 initiated the detachment at a minor location or even at a small local point or area wherefrom the releasing spreads.
(126) Emphasis is made that the flexible release structure 71 shown in the figures is just an example and that any release structure that can flex to expand away from the modified holder component 35, optionally also be able to move at least a distance inside the hole 38 of the modified holder component 35, is within the scope of the present invention.
(127) The flexible release structure 71 of the exemplary embodiment is composed of two opposite pieces of pleated release liner, such as silicon-coated paper. The opposite pleatings 72a,72b can expand upwards in the direction C away from the modified holder component 35 to same or different extent depending on the force that pulls at them and until this force is released again.
(128) In accordance with the present invention the occluding force on the skin tag sustains due to the tensioning of the pressure members. Therefore the cross section of the pedicle of the skin tag 42 or other transition to the skin narrows and vital blood supply to the skin tag eventually stops completely with the result that the skin tag withers away and separates from the skin surface 43.
