Abstract

A skin treatment device including a support body in the form of an elongated stem 12; two resiliency flexible axles and two rollers 18, 20. The axles are fixed to the stem at proximal ends thereof and extend outwardly from opposite sides of the stem. The axles define axes of rotation along their lengths which are co-planar and define an oblique angle between them. Each roller is rotatably supported on a different one of the axles and has a contact surface with radially-extending needles 30 for penetrating the skin of a person to deliver a bioactive ingredient into the skin. The angled axles provide for the rollers to follow the natural curvature of the body of the person while the contact surfaces of the rollers maintain a high degree of contact with the person's skin.

Description

A SKIN TREATMENT DEVICE
FIELD OF INVENTION
The invention relates to a skin treatment device.
SUMMARY OF INVENTION
According to a first aspect of the invention there is provided a skin treatment device including
a support body;
two support arms which are fixed to the support body at proximal ends thereof and which extend outwardly from opposite sides thereof; and
at least two rollers, each having a contact surface with radially-extending needles for penetrating the skin of a person to deliver a bioactive ingredient into the skin, each of the rollers being rotatably mounted to a different one of the support arms so as to be rotatable about axes of rotation which are co-planar and angled relative to one another. The support arms may be of a resiliently flexible material, thereby permitting the support arms to bend when a force is applied to the support body as the rollers are displaced along a surface of a region of the person's body, thereby permitting the rollers to conform to the external profile of said body region so as to provide for greater contact between the rollers and the body region.
The skin treatment device may have a handle which is removably attached to the support body.
BRIEF DESCRIPTION OF DRAWINGS
Further features of the invention are described hereinafter by way of a non-limiting example of the invention, with reference to and as illustrated in the accompanying diagrammatic drawings. In the drawings:
Figure 1 shows a bottom view of a skin treatment device in accordance with the invention, showing hidden detail, wherein the handle is partially fitted to the support body;
Figure 2 shows a bottom view of the skin treatment device of Figure 1 wherein the handle is fully fitted to the support body;
Figure 3 shows a top view of the skin treatment device of Figure 2;
Figure 4 shows an end view of the skin treatment device of Figure 2; and
Figure 5 shows a perspective view of the skin treatment device of Figure 2.
DESCRIPTION OF PREFERRED EMBODIMENTS
With reference to the drawings, a skin treatment device in accordance with the invention, is designated generally by the reference numeral 10. The skin treatment device 10 comprises, broadly, a support body in the form of an elongated stem 12, two support arms 14, 16 and two rollers 18, 20.
The elongated stem 12 has a head section 22 and a mounting section 24. The head section has a constant hexagonal profile from its distal end to its proximal region when viewed in cross-sectional end view, which tapers down in its proximal region towards the mounting section. The mounting section of the stem has a constant rectangular profile when viewed in cross-sectional end view forming a blade 25.
The elongated stem has holes 26, 28 defined in its head section into which the two support arms 14, 16, respectively, are fixedly secured. More particularly, the holes are screw-threaded and the proximal ends of the support arms define external screw thread formations 29 thereby to permit the support arms to be screwed into the holes. The support arms extend perpendicularly outwardly from the slanted edges at opposite sides of the elongated stem and are angled relative to one another. More particularly, the support arms define axes of rotation along their lengths which are co-planar and define an oblique angle between them. The support arms are of a resiliency flexible material.
Each of the rollers 18, 20 of the skin treatment device has a contact surface with radially-extending needles 30 for penetrating the skin. More particularly, the needles protrude from the rollers for at least 0.2 mm and as much as 5 mm.
In use, the needles 30 deliver a bioactive ingredient into the skin. Furthermore, needles of sufficient length induce collagen production through the action of the needles causing micro-trauma to the skin. More particularly, when blood vessels are ruptured by the needles, bleeding occurs and platelets are released automatically. The platelets in turn release a variety of growth factors which in turn stimulate the production of normal collagen and the regeneration of tissue.
The support arms 14, 16 are thus in the form of axles on which the rollers are rotatably supported. Each of the rollers 18, 20 is rotatably supported on a different one of the axles and kept in place by a screw-on cap 32 at the distal end of the axle. The parts of the human body have generally curved external profiles. As such, as the rollers 18, 20 are rotatable about axes of rotation which are angled relative to one another, the rollers substantially follow the natural curvature of the body of a person while the contact surfaces of the rollers maintain a high degree of contact with the person's skin. Furthermore, the support arms 14, 16 bend when a force is applied to the support body as the rollers 18, 20 are displaced along a surface of a region of the body of the person. This further assists the rollers to follow the natural curvature of the body of the person to which the rollers are applied thereby to maintain a high degree of contact between the contact surfaces of the rollers and the person's skin as the rollers are rolled over the person's skin. The bending of the support arms also facilitates a substantially uniform depth of penetration into the skin of the person by needles 30 located at different points along the contact surfaces of the rollers.
The skin treatment device 10 includes a handle 34 mounted to its mounting section 24. The handle has resiliency flexible clamping formations 36 and a socket formation 38 defining a socket within which the clamping formations are located. The clamping formations 36 have a first end 42 and a second end 44 and define an opening 40 within which the blade 25 of the elongated stem 12 is clamped. A part of the outside surface of the clamping formations is screw-threaded and a corresponding part of the inside surface of the socket formation is screw-threaded. The outer circumference of the clamping formations tapers down gradually from its first end 42 to its second end 44.
In use, the blade 25 of the elongated stem 12 is received within the opening 40. The socket formation 38 is screwed onto the clamping formations 36 from its second end 44. As the socket formation 38 is screwed onto the clamping formations 36, the clamping formations are displaced inwardly towards one another thereby frictionally engaging the blade 25 and causing the clamping formations to clamp the blade between them.
The Applicant envisages the skin treatment device will allow for the effective introduction of bioactive ingredients into the skin. The Applicant further envisages that the skin treatment device will induce collagen production through the action of the needles causing micro-trauma to the skin.
