Abstract

A speculum includes an upper blade, a lower blade, a link member, a handle portion, a curved portion, and a light source. The link member connects the upper blade and the lower blade to allow the upper blade and the lower blade to move between an open state and a close state. The curved portion connects the lower blade and the handle portion. The light source is disposed on the curved portion.

Claims

1. A speculum, comprising:

an upper blade;

a lower blade;

a link member connecting the upper blade and the lower blade to allow the upper blade and the lower blade to translate vertically between an open state and a closed state;

a curved portion connected to said lower blade and proximally extending obliquely therefrom;

a handle portion connected to said curved portion and proximally extending obliquely therefrom;

the curved portion connecting and disposed between the lower blade and the handle portion; and

a light source comprising at least one lamp and at least one battery within a single container permanently affixed to said curved portion at a position distal to the handle and proximal to the lower blade, wherein a longitudinal side of the container opens onto a recess in the curved portion such that the container and the recess together circumferentially enclose and secure the at least one battery to the curved portion,

wherein a space is defined between the upper blade and the lower blade, and the light source is configured to provide light to said space.

2. The speculum of claim 1, wherein the at least one lamp is disposed on the curved portion and has a light output surface facing the space.

3. The speculum of claim 1, wherein the at least one lamp is a light-emitting diode.

4. The speculum of claim 1, wherein the battery contains only enough energy for a single use of the speculum.

5. The speculum of claim 1, wherein the single container is configured such that a part of the single container containing the battery is linear and is affixed to a linear section of the curved portion.

6. The speculum of claim 1, wherein the speculum includes at least one slit enabling access to a tab switch.

7. The speculum of claim 1, wherein the light source further comprises a tab switch separating the at least one battery and the at least one lamp, wherein the tab switch is removable, and the at least one battery powers the at least one lamp when the tab switch is removed.

8. The speculum of claim 1, wherein the recess is linear.

9. The speculum of claim 1, wherein the single container is configured such that a part of the single container containing the battery is substantially linear and is affixed to a substantially linear section of the curved portion.
