Abstract

A speculum includes a first blade member and a second blade member, each of the first and second blade members having a distal end and an opposing proximal end. A portable illuminator having a light source and at least one battery includes a switch that is accessible through a slit or similar feature in the speculum. According to at least one version, the switch includes an extending tab portion that can extend through the slit or the end of a handle portion of the speculum to enable illumination. In another version, the portable illuminator can be attached to an articulation mechanism that is configured for moving the first and second blade members in relation to one another.

Claims

1. A vaginal speculum comprising:

a first blade member;

a second blade member, each of the first and second blade members including opposing distal and proximal ends; and

an illuminator comprising;

a light source and at least one battery for powering the light source contained in a housing; and

a switch including a removable tab portion that extends from the housing of the illuminator, the tab portion being movable from a first retained position to a second removed position to selectively energize the light source, the speculum including at least one slit enabling access to the tab portion.

2. The speculum of claim 1, further comprising a handle portion extending downwardly from the second blade member, the handle portion having a cavity extending between a distal end and a proximal end thereof.

3. The speculum of claim 2, wherein the at least one slit is provided on at least one of the first blade member, the second blade member or the handle portion.

4. The speculum of claim 2, wherein the illuminator is attached to one of the upper and lower blade members, with the tab portion extending through the proximal end of the handle portion.

5. The speculum of claim 2, further comprising a mechanism for articulating the upper and lower blade members relative to one another, the illuminator being attached to the articulating mechanism and the tab portion extending through the proximal end of the handle portion.

6. The speculum of claim 2, wherein the illuminator is at least partially disposed within the handle portion.

7. A vaginal speculum comprising:

a first blade member;

a second blade member, each of the first and second blade members including opposing distal and proximal ends;

a handle portion downwardly extending from the proximal end of the second blade member and having a distal end at the second blade member and an opposing proximal end, the handle portion having a through cavity having an open end at the proximal end; and

an illuminator comprising;

a light source and at least one battery for powering the light source; and

a switch movable from a first position to a second position to selectively energize the light source, the switch comprising a movable tab portion that is accessible through the open end of the handle portion while the illuminator is contained within the speculum.

8. The speculum of claim 7, wherein the illuminator is attached to one of the first blade member, the second blade member or the handle portion.

9. The speculum of claim 7, further comprising a mechanism that is attached to the proximal end of each of the first and second blade members for adjusting a spacing therebetween, the illuminator being attached to the blade member adjusting mechanism.

10. The speculum of claim 7, wherein the illuminator further comprises a housing retaining the at least one battery and light source.

11. A speculum comprising:

an upper blade member;

a lower blade member, each of the upper and lower blade members including a distal end and a proximal end; and

a portable illuminator comprising at least one battery and a light source sized to fit at least partially within the distal end of one of the upper and lower blade members.

12. The speculum of claim 11, in which the distal end of the upper and lower blade members is defined by a trough-shaped blade portion, the portable illuminator being at least partially disposed within one of the trough-shaped blade portions.

13. The speculum of claim 12, wherein the portable illuminator is fixedly mounted to one of the trough-shaped portions.

14. The speculum of claim 12, wherein the portable illuminator is entirely located within the trough-shaped portion of the upper blade member or the lower blade member.

15. The speculum of claim 11, wherein the portable illuminator further includes an actuable feature for selectively energizing and deenergizing the contained light source.

16. The speculum of claim 15, wherein the blade member supporting the portable illuminator includes at least one slit enabling access to the actuable feature of the illuminator.

17. The speculum of claim 16, wherein the actuable feature is a switch.

18. The speculum of claim 17, wherein the switch includes a movable tab portion extending outwardly from the housing, the movable tab portion extending through the at least one slit.
