Medical device illuminator and charging system
A portable medical illuminator is configured for attachment to a medical device wherein the illuminator includes an illuminator housing and a light source disposed in relation to the housing. A portable rechargeable power supply is connected to the light source, and an inductive charging coil is disposed within the illuminator housing to enable contactless charging of the contained portable power supply.
1. A vaginal speculum comprising:
an upper blade;
a lower blade, each of the upper and lower blades including an inner surface; and
an illuminator comprising:
an illuminator housing;
a light source;
at least one rechargeable battery;
a charging coil disposed within the illuminator housing and coupled to the at least one rechargeable battery; and
wherein at least one of the inner surface of the upper blade or the lower blade or the illuminator housing include at least one attachment feature to enable releasable attachment of the illuminator to the inner surface of the upper or lower blade.
2. The speculum as recited in claim 1 , in which the inner surface of the upper or lower blade includes a pair of spaced guide rails sized to receive the illuminator housing.
3. The speculum as recited in claim 2 , in which the illuminator housing includes at least one tab member sized to engage the pair of spaced guide rails.
4. The speculum as recited in claim 1 , in which the inner surface of the upper or lower blade includes a projecting tab that is sized to engage an opening formed in the illuminator housing.
5. The speculum as recited in claim 1 , in which the upper and lower blades include a distal end and a proximal end, the speculum further comprising:
a mechanism for adjusting a spacing between the upper and lower blades in which a viewing aperture is defined in the proximal end of the upper and lower blades.
6. The speculum as recited in claim 5 , in which the illuminator is disposed within a raised proximal portion of the upper blade, the illuminator being sized and shaped such that a medical target can be examined through the viewing aperture without interference by the presence of the attached illuminator.
7. The speculum as recited in claim 1 , further comprising a handle portion formed at a proximal end of the lower blade.
8. The speculum as recited in claim 1 , in which the light source is at least one LED.
9. The speculum as recited in claim 1 , in which the charging coil is an inductive charging coil.
10. The speculum as recited in claim 9 , further comprising a circuit board disposed distally of the charging coil and the at least one rechargeable battery within the illuminator housing and in which the at least one rechargeable battery and the charging coil are stacked onto one another.
11. The speculum as recited in claim 1 , further comprising a switch disposed within the housing.
12. The speculum as recited in claim 11 , further comprising a sleeve sized and shaped to fit over the illuminator housing and in which removal of the sleeve from the illuminator housing enables the switch to cause automatic energization of the light source.
13. The speculum as recited in claim 12 , in which the sleeve includes at least a portion made from a magnetic material and in which the switch is a magnetic reed switch.
14. A vaginal speculum comprising:
an upper blade;
a lower blade, each of the upper and lower blades including an inner surface in which the upper blade includes a raised proximal portion; and
an illuminator releasably attached to the inner surface of the upper blade within the raised proximal portion, the illuminator comprising:
an illuminator housing;
a light source;
at least one rechargeable battery; and
a charging coil disposed within the illuminator housing and coupled to the at least one rechargeable battery.
15. The speculum as recited in claim 14 , further comprising a moving mechanism for adjusting a relative spacing between the upper blade and lower blade, the upper and lower blades each having a distal trough shaped blade portion and a proximal end defining a viewing aperture, wherein the illuminator is disposed within the raised proximal portion which does not interfere with viewing through the defined viewing aperture.
16. The speculum as recited in claim 14 , in which the inner surface of the upper blade includes at least one feature for releasably retaining the illuminator.
17. The speculum as recited in claim 16 , in which the at least one feature includes a pair of spaced mounting rails, the illuminator housing being sized to fit between the mounting rails.
18. The speculum as recited in claim 17 , in which the light source is disposed at the distal end of the illuminator housing and the charging coil and the at least one rechargeable battery are disposed in stacked relation at a proximal portion of the housing.
19. The speculum as recited in claim 14 , further including a switch disposed within the illuminator housing that is configured to enable automatic energization of the light source.
20. The speculum as recited in claim 19 , wherein the switch is one of an optical, magnetic, capacitive or acceleration switch.
