Abstract
A depilation needle or probe comprising an elongate conductive body (1) the surface of which is covered with insulating material (2), the body (1) having at one end a conductive tip (4) suitable for depilation purposes and at the other end a conductive surface portion (5) which communicates electrically with the tip (4) via the body (1). <IMAGE>
Description
SPECIFICATION
Depilation needle or probe
This invention relates to depilation needles or probes.
Electrical depilatory apparatus comprising a depilation needle or probe which is used to pass an electrical current through a hair folicle whereby it is destroyed is well known. Such apparatus normally comprises a stainless steel needle or probe which is used to contact the hair folicle and through which a current is passed to kill the folicle thereby to prevent further growth of hair therefrom. One of the problems associated with electrical depilation is that the skin surrounding the folicle may be marked, albeit temporarily due to current flowing through surface tissue. This marking of the skin usually manifests itself as scabs and red blotches and it is clearly undesirable. Over a period of years, scarring may appear as the pores shrink as a result of the treatment.
It is an important object of the present invention to provide a depilation needle or probe which can be used without significantly marking the skin or which will at least minimise or reduce skin marking.
According to the present invention a depilation needle or probe comprises an elongate conductive body the surface of which is covered with insulating material, the body having at one end a conductive tip suitable for depilation purposes and at the other end a conductive surface portion which communicates electrically with the tip via the body.
The needle may be bent or cranked.
The needle may be made of stainless steel.
The insulating material may comprise a plastics material such for example as polytetrafluroethylene.
The insulating material will obviously be chosen to be non-toxic and it may comprise a non-toxic paint or varnish. The insulating material may be a combination of a hardener, for example Trimite
J4602 hardener, and a non-toxic paint, for example 301/A46 non-toxic paint.
The exposed conductive tip should ideally be about one millimetre in length.
The tip may comprise a cylindrical extension of the body having a reduced diameter in order to permit insertion between a hair and its pore.
By providing a depilation needle or probe according to the present invention, a current may be passed along the needle so as to bypass surface layers of skin and to pass into the body at a region adjacent the hairfolicle and thus it is simple to apply to a folicle a suitable depilation current without damaging the surface tissue overlying it.
Some embodiments of the invention will now be described solely by way of example with reference to the accompanying drawings in which:
Figure 1 is a somewhat schematic sectional view of a depilation apparatus including a needle; and
Figure 2 is a somewhat schematic sectional
view of depilation apparatus which includes a
needle of alternative design.
Referring now to Figure 1, a depilation needle
comprsies a first surgical stainless steel body
portion 1 which is generally circular in cross
section and which is coated with a thin insulative
plastics coating 2. The body portion 1 is bent or
cranked at a region 3 and extends to define an
uninsulated surgical steel depilation tip 4 at one
end. The end of the body portion 1 remote from
the tip 4 is also uninsulated and comprises a
shank portion 5 which is received into a plated
brass chuck 6 through which depilation currents
are fed to the needle. The metal chuck 6 is
supported in a body 7 which is fabricated from
insulating material such as a plastics material.
The insulative plastics coating 2 can be
provided on the body portion 1 by various
methods including dipping the body portion 1 into the plastics material, painting or spraying the plastics material onto the body portion 1, and electro-depositing the plastics material onto the body portion 1.
Referring now to Figure 2 wherein parts corresponding to those shown in Figure 1 bear the same numerical designations, a needle 8 is
provided which is similar to the needle shown in
Figure 1 but which is straight and which does not therefore include the cranked region 3. As can be seen most clearly in Figure 2, the needle 8 includes an end part which includes an
uninsulated tip 9 which is generally finer than a
main body portion 10 of the needle 8 and which can therefore be inserted into the skin so that the whole of the conductive tip 9 lies beneath the surface of the skin and next to the bulb of a hair folicle to be destroyed.
It will be appreciated that by using a depilation needle or probe as shown in Figure 1 or Figure 2 it is possible to deliver an electrical current directly to a region below the skin surrounding a hair folicle without passing current through surface tissue and thus it will accordingly be appreciated that marking due to current passing through surface tissue is avoided.
It will be appreciated that various modifications may be made to the needle shown without departing from the scope of the invention and for example curved needles may be used which are coated with a layer of any suitable non-toxic insulating material. Apart from the coating of the insulating material, the needle may otherwise be of various known designs so that needles of the present invention may be used in a variety of known depilatory machines if desired. Also, the needles may be made of materials other than surgical stainless steel.
