Abstract

An illuminator for use with a variety of end use light emitting devices for administering light for therapy and/or observation of an infant. One of the end use emitting devices is a device to provide phototherapy to the infant and is prevented by the illuminator from emitting light that has not been filtered to select the desire spectrum of wavelengths for phototherapy. The illuminator prevents the introduction of a connector to the phototherapy device from being inserted to an operative, secured position unless the proper filter is in position to filter out all of the undesired wavelengths before the light radiation can reach the phototherapy end use emitting device. Other end use light emitting devices may, however, be used with the same illuminator and their connectors are readily inserted into the illuminator to receive light radiating from the illuminator to the end use light emitting device.

Claims7

Dependent claims

An illuminator for illuminating the connector end of one of a plurality of fiberoptic cables having at the other end thereof, light emitting devices for use with infants, at least one of such light devices being a phototherapy light device, said illuminator comprising:

a housing having an opening therein of a predetermined diameter to accept each of said plurality of connector ends and to removably retain such connectors in secured position to said housing,
an illuminator lamp positioned within said housing and adapted to direct light radiation toward the ends of each such connector when retained in said secured position to said housing,
a receptor means having a plurality of apertures of differing diameters, each diameter being of a dimension to snugly receive the end of one of said connectors when such connector is in said secured position, said aperture receiving the phototherapy device connector having a diameter larger than the diameter of any other aperture such that the phototherapy device connector cannot be received within any other aperture,
light filter means affixed to said receptor means and covering at least one of said apertures to filter the light radiation passing from said illuminator lamp to the end of at least one of said connectors, said filter means covering said aperture receiving the phototherapy device connector to limit light radiation therethrough to a predetermined wavelength spectrum nanometers,
means to move said receptor to selectively position said apertures to position only one of said apertures at a time between said illuminator lamp and the end of one of said connectors, such that only one connector may be positioned in said secured position at a time.

2 more elements

An illuminator for selectively supplying light radiation to one of two light emitting devices for use with infants, each of said light emitting devices being positioned at one end of a fiberoptic cable and each having a connector on the other end of the fiberoptic cable, said two connectors being of differing diameters, one of said light emitting devices being a phototherapy light device, said illuminator comprising:

a housing having an opening therein of a predetermined diameter to accept both of said connector ends and to retain such connectors in secured position to said housing,
an illuminator lamp positioned within said housing and adapted to direct light radiation toward the end of each connector when retained in said secured position to said housing,
A receptor means within said housing and having a pair of apertures of differing diameters, each diameter being of a dimension to snugly receive one of said two connectors in order for said connectors to be in said secured position, said diameter of said aperture receiving said connector having the phototherapy device attached thereto having a larger diameter that said other aperture,
a light filter associated with said receptor means and covering said aperture adapted to snugly receive said connector having the phototherapy device attached thereto, said filter limiting the passage of radiation through said aperture to a predetermined spectrum,
a slide for moving said receptor means to selectively position either of said apertures to receive only one of said connectors at a time to a said secured position, wherein said connector having the phototherapy device attached thereto may only be in said secured position in said housing when said larger diameter aperture is in position to receive the connector of the phototherapy device.
