Abstract

A tip of a needle is inserted into large vein of a patient. The needle is mounted in a butterfly device axially engaged to a generally cylindrical housing containing a Y-connector. A pharmaceutically acceptable solution is fed to the needle through the Y-connector to the housing. A quartz optic fiber is fed through the housing and needle to the tip of the needle in the patient'"'"'s venous system. A source of UV and visible light directs both UV and visible light alternatively through the optic fiber to the patient'"'"'s venous system to kill pathogens in the venous system.

Claims

1. An apparatus for destroying pathogens in a venous blood vessel comprising:

(a) a housing having a first and second passageway leading to a cylindrical body, an end portion of the body distal from the first and second passageway enclosing an annular needle housing;

(b) a needle having a first portion mounted in the annular needle housing and a second portion extending outwardly to a tip for inserting into a vein of a patient;

(c) a sealed enclosure containing a pharmaceutically acceptable solution having a conduit leading to one of the passageways;

(d) a first end portion of a quartz optic fiber passing through one of the passageways and through the needle to the tip;

(e) a second portion of the quartz optic fiber connected through a hollow tapered connector to a first end of a fiber optic bundle, the fiber optic bundle connected at a second end to a source of UV and visible light whereby the UV and visible light are alternatively conducted to the tip of the needle, while the solution is flowing through the needle to the tip; and

(f) the second portion of the quartz optic fiber centered through a center bore in a ball positioned in the hollow tapered connector, the tapered connector attached to a terminal for the quartz fiber optic bundle.

2. An apparatus according to claim 1 wherein the annular needle housing has a butterfly wing configuration attached to an exterior surface of the housing.

3. An apparatus according to claim 1 wherein the needle is about a 19 gauge.

4. An apparatus according to claim 1 wherein the conduit from the solution in a bag passes through a connector monitoring the flow of solution.

5. The apparatus according to claim 4 wherein the connector is adapted to permit a flow of about one drop per second.

6. The apparatus according to claim 1 wherein the source of UV and visible light is a lighted bulb separated from the second end of the fiber optic bundle by either a UV or visible light filter.

7. The apparatus according to claim 1 wherein the hollow tapered connector connecting the second portion of the quartz optic fiber to the first end of the fiber optic bundle contains the ball movable within a portion of the tapered connector, the ball having a central bore for centering the second portion of the quartz optic fiber with respect to the fiber optic bundle.

8. An apparatus for destroying pathogens in a venous blood vessel comprising:

(a) a housing having a first and second arm leading to a cylindrical body, an end portion of the cylindrical body distal from the first and second arms enclosing a needle housing;

(b) a needle having a first portion mounted in the needle housing and a second portion extending outwardly to a tip adapted to be inserted into a vein of a patient;

(c) a liquid solution source having a conduit leading to the first arm;

(d) a first end portion of a quartz optic fiber passing through the second arm and through the needle to the tip;

(e) a second portion of the quartz optic fiber centered through a center bore in a ball movably positioned in a hollow tapered connector, the hollow tapered connector attached at a wide mouth to a terminal for a quartz fiber optic bundle and at a narrow pointed end to the second arm of the housing; and

(f) the fiber optic bundle connected at an end distal from the terminal to a source of UV and visible light whereby the UV and visible light is conducted to the tip of the needle while the solution is flowing through the needle to the tip.

9. The apparatus according to claim 8 wherein the liquid solution source is a bag containing normal saline.

10. The apparatus according to claim 8 wherein the source of UV and visible light is a lighted bulb spaced apart, from an end of the fiber optic bundle distal from the connection with the tapered connector, by either a UV or visible light filter.

11. The apparatus according to claim 8 wherein the first portion of the needle is mounted in a hub.

12. The apparatus according to claim 8 wherein the tapered connector has external threads at the wide mouth threaded to internal threads in the terminal for the quartz fiber optic bundle.

13. The apparatus according to claim 8 wherein the pointed end of the tapered connector is engaged in a top end of the second arm.

14. A method of treating venous blood of a patient by exposing the venous blood to a UV and a visible light comprising:

(a) providing a Y-shaped housing having an annular internal diameter wherein a terminal end of the Y-shaped housing encloses the hub of a needle housing;

(b) providing a needle having a first end mounted in the hub and a second end tip protruding outside the hub;

(c) providing a saline solution bag with a conduit from the bag directed to a first arm of the Y-shaped housing;

(d) providing a quartz optic fiber and passing a first end of the quartz optic fiber through a second arm of the Y-shaped housing and through the needle to the tip, connecting a second end of the quartz optic fiber to a first end of a quartz fiber optic bundle which is connected at a second end separately to the UV and the visible light source wherein the second end of the quartz fiber optic is centered through a center bore in a ball positioned in a hollow tapered connector, the tapered connector attached to a terminal for the quartz fiber optic bundle;

(e) providing the UV light at 200 to 400 nanometers and the visible light at 450 to 1100 nanometers;

(f) inserting said needle into a vein of a patient in which a blood stream is flowing whereby the UV and visible light and saline solution are conducted to the tip of the needle; and

killing pathogens in the venous blood by exposure to the UV and visible light.

15. The method of claim 14 wherein the terminal end of the Y-shaped housing is provided with an exterior annular diameter decreasing in width from the first and second arm.

16. The method of claim 14 wherein the needle housing is provided with a butterfly wing configuration attached to an exterior surface of the hub.

17. The method of claim 14 wherein the needle is provided at about 19 gauge.

18. The method of claim 14 wherein the conduit from the saline solution bag is passed through a connector monitoring the flow of solution.

19. The method of claim 14 wherein the visible light source is provided by a light bulb separated from the second end of the quartz fiber optic bundle by either a UV or visible light filter.

20. The method of claim 18 wherein the connector is further provided as a structure permitting a flow of about one drop per second.
