Abstract

A vaginal speculum apparatus includes a portable illumination assembly that is releasably attached to one of the upper blade and lower blade of a disposable vaginal speculum. The portable illumination assembly is defined by a housing that retains at least one LED and a portable power supply. The portable illumination assembly can be energized by an externally accessible member after the illuminator has been attached to the speculum.

Claims

1. A vaginal speculum apparatus, said apparatus comprising:

a portable illumination assembly defined by a housing that retains a portable power supply, at least one LED and an integral curved light pipe made from a light transmissive material, said at least one LED being adjacent to and optically coupled to a proximal end of said integral curved light pipe; and

a vaginal speculum comprising an upper blade and a lower blade, said lower blade including a trough-shaped blade section and a handle portion that receives a portion of said portable illumination assembly and wherein said portable illumination assembly, including said integral light pipe, is releasably attached to the handle portion of said speculum such that the curved light pipe of said illumination assembly extends into the trough-shaped blade section of said speculum.

2. An apparatus as recited in claim 1, wherein said upper blade is movable relative to said lower blade.

3. An apparatus as recited in claim 1, wherein said portable illumination assembly includes a mechanism for energizing said at least one LED.

4. An apparatus as recited in claim 3, wherein said LED energizing mechanism comprises a switch disposed on the exterior of said portable illumination assembly housing.

5. An apparatus as recited in claim 4, wherein said speculum includes at least one opening that permits access to said LED energizing mechanism of said portable illumination assembly.

6. An apparatus as recited in claim 1, wherein said handle portion includes at least one set of rails.

7. An apparatus as recited in claim 1, wherein said speculum is disposable.

8. An apparatus as recited in claim 1, wherein the entire apparatus is disposable.

9. A vaginal speculum apparatus, said apparatus comprising:

a portable illumination assembly comprising a portable power source, at least one LED, and a mechanism for energizing said at least one LED within a common housing; and

a vaginal speculum having an upper blade a lower blade, and a mechanism disposed at a proximal end of said speculum for permitting relative movement between said upper blade and said lower blade to enable dilation of a patient, said movement mechanism including a lever portion extending from a proximal end of said upper blade and defining an opening, said portable illumination assembly being entirely contained within the proximal end of one of said upper blade and said lower blade and releasably attached thereto and in which said illumination assembly is accessed for at least one of energization of said at least one LED and removal through said opening.

10. An apparatus as recited in claim 9, wherein said speculum includes a cavity disposed in said handle portion, said cavity including at least one set of rails.

11. An apparatus as recited in claim 9, wherein said speculum is disposable.

12. An apparatus as recited in claim 9, wherein the entire apparatus is disposable.

13. An apparatus as recited in claim 9, wherein said portable illumination assembly is attached to said lower blade such that the retained LED is disposed at the proximal end of said lower blade.

14. An apparatus as recited in claim 9, wherein said portable illumination assembly is attached to said lower blade and in which at least a portion of said illumination assembly extends outside a handle portion thereof.

15. An apparatus as recited in claim 9, wherein said energizing mechanism comprises a switch.

16. A method for assembling a vaginal speculum apparatus, said apparatus comprising a vaginal speculum having an upper blade and a lower blade, said lower blade and said upper blade each including a proximal end and a mechanism for moving said blades relative to one another, said movement mechanism comprising a lever portion extending from the proximal end of said upper blade defining an opening and a portable illumination assembly comprising at least one battery and at least one LED retained within a common housing, said method comprising the steps of:

configuring said portable illumination assembly with an externally accessible mechanism for energizing said at least one LED; and

attaching said portable illumination assembly to the proximal end of one of said lower blade and said upper blade; and

accessing the energizing mechanism of said attached illumination assembly through the opening.

17. A method as recited in claim 16, wherein at least one of said speculum and said entire apparatus is disposable.

18. A vaginal speculum apparatus, said apparatus comprising:

a portable illumination assembly comprising a portable power source, at least one LED, and a mechanism for energizing said at least one LED within a common housing; and

a vaginal speculum having an upper blade and a lower blade, each of said upper blade and said lower blade having a distal end and an opposing proximal end, and a mechanism for permitting relative movement between said upper blade and said lower blade to enable dilation of a patient, said movement mechanism including a downwardly lever portion extending from the proximal end of said upper blade that engages a yoke extending upwardly from the proximal end of said lower blade, each of said lever portion and said yoke defining an opening of said speculum, said portable illumination assembly being attached to the proximal end of one of said upper blade and said lower blade and disposed such that the energization mechanism can be accessed for energizing said at least one LED only through said defined opening.

19. An apparatus as recited in claim 18, wherein said energizing mechanism comprises a switch.
