Abstract
A middle ear insufflation device to relieve pressure differential across the tympanic membrane resulting from rapid changes in altitude or intrinsic Eustachian Tube Dysfunction, the device having a compressible bladder member and an ear canal sealing member such that the bladder member can be compressed and released to reduce or increase pressure within the ear canal that is then translated across the tympanic membrane affecting internal pressure within the middle ear space, thereby helping to facilitate normalization of middle ear pressure through the Eustachian Tube.
Claims19
A method of reducing an air pressure differential between the external ear canal and the internal middle ear, the method comprising the steps of:
- providing an insufflation device comprising a compressible bladder member and an ear canal sealing member, said device adapted to expel or suction air and structured so as to be insertable into an external ear canal;
- ascertaining whether the air pressure differential is such that the external pressure is greater than the pressure within the middle ear or whether the external pressure is less than the pressure within the middle ear;
- if the external pressure is greater than the pressure within the middle ear, compressing said bladder member to expel air within the bladder member, inserting said insufflation device into the external ear canal such that said ear canal sealing member seals the ear canal, and releasing the compression of said bladder member to suction air from the ear canal into said bladder member;
- and
- if the external pressure is less than the pressure within the middle ear, inserting said insufflation device into the external ear canal such that said ear canal sealing member seals the ear canal, compressing said bladder member to expel air from said bladder member into the ear canal.
An ear insufflation device capable of reducing an air pressure differential between the external ear canal and the internal middle ear, said device comprising:
- a compressible bladder member adapted to expel and suction air, said compressible bladder member having a volume of approximately 5 milliliters;
- and
- an ear canal sealing member joined to said compressible bladder member and adapted to seal an external ear canal upon insertion into the external ear canal.
An ear insufflation device capable of alleviating pain and discomfort arising from an air pressure differential between the external ear canal and the internal middle ear, said device comprising:
- a compressible, thin-walled, bladder member adapted to expel and suction air, said compressible bladder member, said compressible bladder member comprising an elongated tube member;
- and
- an ear canal sealing member joined to said compressible bladder member and adapted to seal an external ear canal upon insertion into the external ear canal, said ear canal sealing member comprising a cushioning member, an annular sealing portion having one or more annular rib members, and a bore receiving said tube member.
