(1) Field of the Invention

The disclosure relates to light application devices and more particularly pertains to a new light application device for killing pathogens on tissue and proximate thereto. The present invention discloses a device comprising a first fiber optic cable for directing UV light onto tissue being manipulated as part of a medical procedure, or such a device also incorporating a suction tube or a second fiber optic cable for directing visible light onto the tissue.


(2) Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98

The prior art relates to light application devices, which may comprise UV light or far UV light devices for destroying pathogens on tissue without harming human cells. What is lacking in the prior art is a device comprising a first fiber optic cable for directing UV light onto tissue being manipulated as part of a medical procedure, or such a device also incorporating a suction tube or a second fiber optic cable for directing visible light onto the tissue.


BRIEF SUMMARY OF THE INVENTION

An embodiment of the disclosure meets the needs presented above by generally comprising a tube, which is configured to be utilized in a medical procedure, such as a tube intended for suctioning, fluid flow, or endoscopy. A first fiberoptic cable is engaged to a wall of the tube so that a first end of the first fiberoptic cable is positioned proximate to a first terminus of the tube. The first fiberoptic cable has a second end configured to operationally engage an ultraviolet C light emitter so that ultraviolet C light is emitted proximate to the first terminus of the tube. The first fiberoptic cable is configured to direct the ultraviolet C light from the ultraviolet C light emitter so that the ultraviolet C light impinges upon tissue and pathogens proximate to the first terminus of the tube to inactivate the pathogens.

DETAILED DESCRIPTION OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1 through 9 thereof, a new light application device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.


As best illustrated in FIGS. 1 through 9, the far ultraviolet light application device 10 generally comprises a tube 12, which is configured to be utilized in a medical procedure. The tube 12 may be configured for suctioning, fluid flow, or endoscopy. For example, the tube 12 may comprise a suction tube 14, as shown in FIGS. 3 and 9, a suction catheter 16, as shown in FIG. 2, an endoscopy tube (not shown), an intravenous tube (not shown), a shunt (not shown), a dialysis catheter (not shown), and the like. The suction catheter 16 may have a perforated bladder 50 engaged to a first terminus thereof.


A first fiberoptic cable 18 is engaged to a wall 20 of the tube 12 so that a first end 22 of the first fiberoptic cable 18 is positioned proximate to the first terminus 24 of the tube 12. The first fiberoptic cable 18 has a second end 26 configured to be operationally engaged to an ultraviolet C light emitter (not shown) so that ultraviolet C light is emitted proximate to the first terminus 24 of the tube 12. The first fiberoptic cable 18 is configured to direct the ultraviolet C light from the ultraviolet C light emitter so that the ultraviolet C light impinges upon tissue and pathogens proximate to the first terminus 24 of the tube 12 to inactivate the pathogens. The ultraviolet C light emitter emits at 222 nanometers so that the ultraviolet C light is nondamaging to mammalian tissue.


In one embodiment, as shown in FIG. 8, the tube 12 comprises a pipe 28, which is integral to a medical instrument 30. The pipe 28 is circumferentially complementary to a prior art suction tube lacking the first fiberoptic cable 18. The pipe 28 is configured to selectively engage the prior art suction tube so that the prior art suction tube is removably and operationally engaged to the pipe 28. The prior art suction tube is configured to remove debris, droplets, particles, and aerosols generated during the medical procedure performed using the medical instrument 30 and thus serves to reduce a probability of transfer of pathogens to a surrounding environment and persons therein, relative to a prior art medical instrument lacking the pipe 28.


The medical instrument 30 may comprise an examination instrument, such as a tongue retractor 32, as shown in FIG. 8, a surgical instrument, a dental instrument, or a veterinary instrument. For example, the medical instrument 30 may comprise a retractor (not shown), a probe (not shown), a clamp (not shown), a forceps (not shown), and the like.


In another embodiment, as shown in FIGS. 3-7, the device 10 comprises an adapter 34, which is selectively engageable to the tube 12. The adapter 34 is configured to selectively engage a medical instrument 30 so that the tube 12 is removably engaged to the medical instrument 30. The adapter 34 may comprise a plate 36, which is shaped complementarily to a portion 38 of the medical instrument 30. A set of clips 40 is engaged to the plate 36 and is configured to engage the medical instrument 30 so that the adapter 34 is removably engaged thereto with the plate 36 overlying the portion 38 of the medical instrument 30. A receptacle 42 engaged to the plate 36 is complementary to the tube 12. The receptacle 42 is positioned for insertion of the tube 12 to removably engage the tube 12 to the adapter 34. The adapter 34 shown in FIGS. 3-7 is directed to use with a tongue retractor 32, but the present invention anticipates a variety of adapters 34 for use with a multitude of medical instruments 30.


In yet another embodiment, a second fiberoptic cable 44 is engaged to the tube 12 and terminates proximate to the first terminus 24 of the tube 12. The second fiberoptic cable 44 is configured to be operationally engaged to a visible light emitter (not shown) so that visible light is emitted proximate to the first terminus 24 of the tube 12. The second fiberoptic cable 44 is configured to direct the visible light so that the visible light illuminates the tissue proximate to the first terminus 24 of the tube 12. The visible light emitter comprises a light emitting diode (not shown).


In still yet embodiment, as shown in FIG. 8, a first connector 46 is engaged to the second end 26 of the first fiberoptic cable 18. The first connector 46 is configured to selectively engage a second connector 48. The second connector 48 is operationally engaged to the ultraviolet C light emitter. The first connector 46 is positioned to selectively engage the second connector 48 to optically engage the first fiberoptic cable 18 to the ultraviolet C light emitter. Also, in this embodiment, engagement of the first connector 46 to the second connector 48 may optically engage the second fiberoptic cable 44 to the visible light emitter.


In use, the tube 12 draws in air from the immediate vicinity of the medical instrument 30. The air carries into the tube 12 fluids, droplets, particles, and aerosols that may contain pathogens. The second fiberoptic cable 44 directs the visible light onto the tissue proximate to the first terminus 24 of the tube 12 and aids in the medical procedure. The first fiberoptic cable 18 directs the ultraviolet C light from the ultraviolet C light emitter to impinge upon the tissue and pathogens proximate to the first terminus 24 of the tube 12 to inactivate the pathogens.


With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.


Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
