Abstract
An adapter for a handpiece system , especially for use in conjunction with medical and dental light emitting apparatus for the transmission of light to cure photo-polymerisable materials. A device, preferably in the form of an adapter, enables the user to correctly match the polarity of the contacts in the supply hose or conduit with those of the light emitting apparatus.
Claims30
An adapter within a handpiece system including a supply conduit and a medical instrument having an electrical operating element thereon wherein electrical power is transmitted from said supply conduit through said adapter to said medical instrument, said adapter being selectively switchable to match the polarity of electrical power transmitted from the supply conduit to that needed by the operating element.
Light emitting apparatus including a light source requiring a selected polarity of power supply connected to a supply conduit through which electrical power is transmitted and an adapter connected between the light source and the supply conduit, said adapter being selectively switchable to match the polarity of electrical power transmitted from the supply conduit to that required by the light source.
A handpiece system comprising
- a supply hose having a distal end coupling device with supply contacts for supplying electrical power transmission from an external power source,
- a handle sleeve having a light source contained therein with receiving contacts for connecting the light source to receive electrical power from said coupling device, and
- an adapter connected between said coupling device and light source selectively switchable to match the polarity of electrical power transmitted from the power source to that needed by the light source.
A process for matching the polarity of contacts within a handpiece system comprising at least two separable parts a first of which is adapted to supply electrical power of one polarity and the second of which is adapted to receive electrical power and requires power of a selected polarity to be operable, comprising the steps of
- disconnecting the two separable parts,
- inserting and electrically connecting an adapter between said parts in an arbitrary initial position in an interface between said parts with the two parts joined together with the adapter,
- attempting to operate the second part with an electrical connection provided between said parts through said adapter in said initial position,
- and if operation of the second part does not occur moving the adapter into a second position different from said initial position to reverse the polarity of power supplied to said second part from the polarity provided with the adapter in said initial position.
