TITLE
[0001] Electrical Apparatus For Treating Ear Barotrauma FIELD
[0001] Electrical Apparatus For Treating Ear Barotrauma FIELD
[0002] There is described an electrical apparatus that is used for treating ear barotrauma.
BACKGROUND
BACKGROUND
[0003] Ear barotrauma is a condition in which pressure within the inner ear causes pain.
Infants under the age of seven years of age are particularly susceptible to experiencing ear barotrauma, as their sinuses are not fully developed. A change in altitude, such as is experienced during an aircraft flight can induce ear barotrauma.
Infants under the age of seven years of age are particularly susceptible to experiencing ear barotrauma, as their sinuses are not fully developed. A change in altitude, such as is experienced during an aircraft flight can induce ear barotrauma.
[0004] It has long been known that heat expansion can be beneficial in relieving the symptoms of ear barotrauma. Experienced airline flight attendants used to place hot water on a towel, insert the towel into a cup and position the cup over an ear of a passenger (usually an infant) experiencing ear barotrauma. This practice ceased due to liability concerns when some passengers were scalded.
[0005] Canadian Patent Application 2,839,225 describes an apparatus for treating ear barotrauma. There will hereinafter be described an alternative apparatus for treating ear barotrauma.

The interior surface defines a heat chamber having a first end and a second end. The first end is closed by an end wall of the body. The second end is open with an ear receiving opening.
A battery powered electric heat source is positioned within the heat chamber at the first end. The heat source is selectively activated by a switch located on the exterior surface. A
seal is positioned around the ear receiving opening.
BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0016] An electrical apparatus for treating ear barotrauma generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 8.
Structure and Relationship of Parts:
Structure and Relationship of Parts:
[0017] Referring to FIG. 2 and FIG. 3, apparatus 10 includes a hollow body 12 having an exterior surface 14 and an interior surface 16. Interior surface 16 defines a heat chamber 18 having a first end 20 and a second end 22. First end 20 is closed by an end wall 24 of body 12. Second end 22 is open with an ear receiving opening 26. A battery powered electric heat source 28 is positioned within heat chamber 18 at first end 20. Heat source 28 is selectively activated by a switch 30 located on exterior surface 14. A seal 32 is positioned around ear receiving opening 26.
[0018] While it is possible to treat one ear at a time, it is preferable to treat both ears at once. Referring to FIG. 1 and FIG. 4, in order to treat both ears at once, two of bodies 12 are provided and a structure, such as a band 34, provided for mounting two bodies 12 to a human head with a first 12A of the two bodies positioned over a left ear and a second 12B of the two bodies 12 positioned over a right ear. Referring to FIG. 5, it is preferred that band 34 be spring tensioned to go to a stored position when not in use.
[0019] Although one can use non-rechargeable batteries, which are periodically replaced, it is preferable that rechargeable batteries be used. Referring to FIG. 4 and FIG. 5, when rechargeable batteries are used means for recharging the batteries can be built into heat source 28 and a port 36 provided on exterior surface 14 for connecting a power source to recharge a rechargeable battery powering the heat source.
[0020] Referring to FIG. 6, there is illustrated a circuit diagram for the apparatus 10.
[0021] Referring to FIG. 7, there is illustrated a Control Circuit that provides control, indication, and charging to the system. The battery and element are connected to JP1, when a 500mA source is connected to the USB port, the output MOSFET gate voltage is pulled low via the logic MOSFET controlled by the source voltage. The 500mA source voltage is provided to the charge indicator LED (green), and to U1 (charge management IC) that in turn manages the charging cycle of the connected battery. When source voltage is removed the gate voltage of the output MOSFET is not forced low, and when voltage exceeding the gate threshold voltage is reached the system will operate. When the main button Si is depressed, C3 is charged, when the line voltage exceeds the output MOSFET's gate threshold voltage battery voltage is applied to the external heating element, and to the output indicator LED
(red). When the button Si is released C3 will drain its charge through R2 until the gate voltage threshold is crossed and output is disabled. The time required for C3 to drain to the threshold voltage is a function of capacitance of C3, and resistance of R2.

[0022] Referring to FIG. 8, there is illustrated a Secondary Circuit that provides basic switching and charging for the opposing headset cup. The operation of the secondary circuit is similar to that of the Control Circuit, however no indication or control is provided directly.
Instead the switch and supply current are provided from the Control Circuit via JP2. The secondary circuit has a dedicated charge management controller, source power is supplied from the Control Circuit.

Instead the switch and supply current are provided from the Control Circuit via JP2. The secondary circuit has a dedicated charge management controller, source power is supplied from the Control Circuit.
Operation:
[0023] Referring to FIG. 1, when a child is experiencing discomfort due to ear barotrauma, two bodies 12 are positioned on the child's head using band 34 with a first 12A
of the two bodies positioned over a left ear and a second 12B of the two bodies 12 positioned over a right ear. Switch 30 is then activated to cause electric heat source 28 to generate heat within heat chamber 18. Seal 32 positioned around ear receiving opening 26 forms a seal against the side of the child's head to retain heat within heat chamber 18.
Referring to FIG.
5, when no longer required, apparatus 10 is removed and retracts into the stored position.
When in the stored position, a USB connector 100 can be inserted into port 36 and connected by cable 102 to a power source for the purpose of recharging in preparation for the next use.

[0024] In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
[0025] The scope of the claims should not be limited by the illustrated embodiments set forth as examples, but should be given the broadest interpretation consistent with a purposive construction of the claims in view of the description as a whole.
