Abstract

A vaginal speculum having an inflatable bladder which includes a central channel and an inlet outlet port. The inflatable bladder may include optical fibers for illumination.

Claims

1. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state,

iii) defining a central channel when in the inflated state, and

iv) having an inlet/outlet port; and

b) optical fibers

wherein the inflatable bladder is formed from a material having a cross section and

wherein the optical fibers are arranged with respect to the inflatable bladder in an arrangement selected from a group of arrangements consisting of;

(a) embedded within the cross section of the material;

(b) attached to an outer surface of the inflatable bladder;

(c) attached to an inner surface of the inflatable bladder; and

(d) arranged within a void defined by the inflatable bladder.

2. The vaginal speculum of claim 1 wherein the inflatable bladder has a proximal end and a distal end, and wherein more of the optical fibers are provided at the distal end of the inflatable bladder than at the proximal end of the inflatable bladder.

3. The vaginal speculum of claim 1 wherein the inflatable bladder has a proximal end and a distal end, and wherein distal tip ends of the optical fibers are provided at the distal end of the inflatable bladder.

4. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state,

iii) defining a central channel when in the inflated state, and

iv) having an inlet/outlet port;

b) a tube which is fitted into, and widens, the central channel of the inflatable bladder; and

c) optical fibers arranged in at least one location selected from a group consisting of (a) embedded within the tube, (b) on an inside surface of the tube, and (c) on an outside surface of the tube.

5. The vaginal speculum of claim 4 further comprising a light source optically coupled with the optical fibers.

6. The vaginal speculum of claim 5 wherein the light source includes a 150 Watt white light source.

7. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state,

iii) defining a central channel when in the inflated state, and

iv) having an inlet/outlet port,

wherein the central channel has a proximal end and a distal end, and wherein the proximal end of the central channel flares outward.

8. The vaginal speculum of claim 7 wherein, when the inflatable bladder is in its inflated state, the distal end includes a longitudinal extension adapted to engage a cervix.

9. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state,

iii) defining a central channel when in the inflated state, and

iv) having an inlet/outlet port,

wherein the inflatable bladder has a proximal end and a distal end, and wherein, when the inflatable bladder is in its inflated state, the distal end includes a longitudinal extension adapted to engage a cervix.

10. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state,

iii) defining a central channel when in the inflated state, and

iv) having an inlet/outlet port,

wherein the central channel of the inflatable bladder is formed of less flexible material than remaining areas of the inflatable bladder such that it stretches less than the remaining areas upon inflation.

11. The vaginal speculum of claim 10 wherein the central channel of the inflatable bladder is formed thicker than remaining areas of the inflatable bladder such that it stretches less than the remaining areas upon inflation.

12. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state,

iii) defining a central channel when in the inflated state, and

iv) having an inlet/outlet port,

wherein the central channel of the inflatable bladder is formed thicker than remaining areas of the inflatable bladder such that it stretches less than the remaining areas upon inflation.

13. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state,

iii) defining a central channel when in the inflated state, and

iv) being formed solely of a flexible material; and

b) a tube which extends through the central channel of the inflatable bladder.

14. The vaginal speculum of claim 13 wherein the central channel of the inflatable bladder has a proximal end and a distal end, and wherein the tube is flared out at its end corresponding to the proximal end of the central channel.

15. The vaginal speculum of claim 13 wherein the inflatable bladder is made from a material selected from a group consisting of (a) rubber, (b) latex, and (c) polyethylene.

16. The vaginal speculum of claim 13 further comprising an inflation device fluidly coupled with an inlet/outlet port of the inflatable bladder.

17. The vaginal speculum of claim 16 wherein the inflation device is selected from a group consisting of (a) a controllable, powered, pump, (b) a hand bulb, and (c) a controllable pressurized gas source.

18. The vaginal speculum of claim 13 wherein at least one of an outer surface and a channel surface of the inflatable bladder is provided with a lubricant.

19. A vaginal speculum comprising:

a) an inflatable bladder, the inflatable bladder

i) having a deflated state and an inflated state,

ii) being adapted for insertion into a vagina in the deflated state and for dilating walls of the vagina in the inflated state, and

iii) defining a central channel when in the inflated state, the central channel being formed by a flexible material; and

b) a tube which extends through the central channel of the inflatable bladder.
