Abstract

A programmable hearing aid having a battery compartment which holds a battery under normal operating conditions is also adapted to hold a coupler member for connecting an external programming device to the hearing aid. To connect an external programming device to the hearing aid, lead wires in contact with the programming device are contacted with battery and programming terminals in the battery compartment by means of a coupling member. The coupling member is shaped to fit in the battery compartment and has electrodes in contact with the lead wires from the programming device arranged for contacting the battery and programming terminals in the battery compartment.

Claims

1. A programmable hearing aid energizable by electrical connection to a battery comprising:

a battery compartment having two battery terminals for contacting the positive and negative terminals of the battery, said battery terminals electrically coupled to circuitry in the programmable hearing aid; and

a programming terminal coupled to programming circuitry in the programmable hearing aid device, said programming terminal being located in said battery compartment;

said battery compartment and programming terminal being physically arranged such that said programmable terminal is utilizable only when said battery is removed from said battery compartment.

2. A programmable hearing aid according to claim 1, additionally comprising a battery compartment door pivotably mounted for adjustment between a closed position within said battery compartment and an open, access position.

3. A programmable hearing aid system, comprising:

a programmable hearing aid energizable by electrical connection to a battery, said programmable hearing aid including a battery compartment having two battery terminals for contacting the positive and negative terminals of the battery, said battery terminals electrically coupled to circuitry in the programmable hearing aid; and

a programming terminal coupled to programming circuitry in the programmable hearing aid device, said programming terminal being located in said battery compartment;

said battery compartment and programming terminal being physically arranged such that said programmable terminal is utilizable only when said battery is removed from said battery compartment; and

a coupling member sized to fit in said battery compartment, said coupling member having a programming electrode in electrical contact with an external hearing aid programming system and a positive electrode and a negative electrode in electrical contact with said external hearing aid programming system;

said coupling member being adapted so that said programming electrode electrically contacts said programming terminal in said battery compartment and said positive and negative electrodes electrically contact said battery terminals in said battery compartment when said coupling member is inserted in said battery compartment.

4. The programmable hearing aid system of claim 3, wherein said programming electrode and said positive and negative electrodes are located on an exterior surface of said coupling member.

5. The programmable hearing aid system of claim 3, wherein said coupling member is generally disk-shaped, said positive and negative electrodes are positioned on opposite surfaces of said coupling member, and said programming electrode is positioned intermediate said positive and negative electrodes on a circumferential surface of said coupling member.

6. In combination, a programmable hearing aid, energizable by electrical connection to a battery, said programmable hearing aid including a battery compartment having two battery terminals for contacting the positive and negative terminals of the battery, said battery terminals electrically coupled to circuitry in the programmable hearing aid;

and a programming terminal coupled to programming circuitry in the programmable hearing aid device, said programming terminal being located in said battery compartment; and

a coupling member having a positive electrode, a negative electrode, and a programming electrode in electrical contact with an external hearing aid programming system, said coupling member mounted in said battery compartment with said positive and negative electrodes in electrical contact with said battery terminals and said programming electrode in electrical contact with said programming terminal;

said coupling member and said battery not being placeable within said battery compartment at the same time.

7. A coupling member for establishing electrical contact between a programmable hearing aid and an external hearing aid programming system, said programmable hearing aid being energizable by electrical connection to a battery;

said coupling member sized to fit in a battery compartment in the programmable hearing aid and having a programming electrode and positive and negative electrodes in electrical contact with the external hearing aid programming system;

wherein said battery must be removed before said coupling member is used to establish contact between said programmable aid and the external hearing aid programming system.

8. A coupling member according to claim 7, wherein said coupling member is generally disk-shaped, said positive and negative electrodes are positioned on an exterior surface of said coupling member generally opposite one another on said coupling member, and said programming electrode is positioned intermediate said positive and negative electrodes on a circumferential surface of said coupling member.

9. A method for programming a programmable hearing aid energized by a battery retained in a battery compartment in the hearing aid by electrical contact with an external hearing aid programming system, the method comprising:

locating a programming terminal in electrical contact with programming circuitry in the hearing aid in the battery compartment;

removing the battery retained in the battery compartment;

then inserting a coupling member having a programming electrode mounted thereon in said battery compartment, and electrically coupling said programming electrode with the external hearing aid programming system and with said programming terminal in the battery compartment.
