Adjustable bite blocks
Embodiments of the present invention relate to an adjustable bite block for positioning within a person's mouth and maintaining the mouth in an open position. The adjustable bite block comprising at least one band of curved material comprising a first portion and a second portion. The first and second portions configured to be coupled to one another so as to define a closed loop with an opening defined therethrough, wherein the first and second portions are further configured to be selectively adjusted relative to one another so as to adjust a radial dimension of the loop, and wherein the band is configured to be positioned within the person's mouth such that at least a portion of the loop maintains the person's mouth in an open position. Embodiments of the adjustable bite block may use snap tabs spaced along the band or a ratchet mechanism for adjustment of the radial dimension.
1. An adjustable bite block for positioning within a person's mouth and maintaining the mouth in an open position, the adjustable bite block comprising:
at least one band of curved material comprising a first portion and a second portion, the first and second portions configured to be coupled to one another so as to define a closed loop with an opening defined therethrough, wherein the first and second portions are further configured to be selectively adjusted relative to one another so as to adjust a radial dimension of the loop, and wherein the band is configured to be positioned within the person's mouth such that at least a portion of the loop maintains the person's mouth in an open position,
wherein the first portion defines at least two slots of different heights, wherein the second portion defines at least one protrusion, and wherein each slot is configured to receive the at least one protrusion to define a radial dimension of the opening.
2. The adjustable bite block of claim 1 , wherein the at least one protrusion of the second portion is configured to be slidably removed from the at least one slot of the first portion and repositioned into a different at least one slot of the first portion to define a different radial dimension of the opening.
3. The adjustable bite block of claim 1 further comprising at least one wall configured for keeping the adjustable bite block in a person's mouth.
4. The adjustable bite block of claim 3 , wherein the at least one wall extends radially from the first portion of the at least one band.
5. The adjustable bite block of claim 1 , wherein each slot comprises an end stop configured to prevent a respective protrusion from being slid past a predetermined point within the respective slot.
6. The adjustable bite block of claim 1 , wherein each slot defines a cross-sectional dimension that decreases from a front part of a respective slot to a back part of the respective slot such that a resistance to engagement of a respective protrusion within the respective slot increases as the respective protrusion is slid further into the respective lot.
