JP6265821B2 - Hearing aid carrying case to prevent spontaneous discharge of battery - Google Patents

Description

The present invention relates to a case for carrying a hearing aid composed of a magnetic rubber to which a case body for storing a hearing aid when not in use while preventing external shocks and a battery removed from the hearing aid are bonded to each other.

As a conventional hearing aid carrying case, a case body is formed from a container portion and a lid portion, and a cushioning pad having a shape adapted to the shape of each hearing aid is placed inside the case body and the lid portion inside the case body. A device that is worn and wrapped around a hearing aid is known. Some of these hearing aid carrying cases are equipped with a small magnetic rubber for storing one or two air batteries (Patent Document 1).

The hearing aid carrying case is stored in the carrying case body by turning off the power switch of the hearing aid when the hearing aid is not used or removing the battery attached to the hearing aid. Small-sized hearing aids such as ear-mounted hearing aids and ear-shaped hearing aids use coin-shaped air zinc batteries for hearing aids. As this battery is also called an air battery, the positive electrode has an air hole, and oxygen in the air is taken in to generate electricity, so the air hole of the air battery is used regardless of the inside or outside of the hearing aid. In the state where the air is vacant, the air battery naturally discharges a little, so it is necessary to block the air hole in the positive electrode to prevent discharge.

The present invention is a portable hearing aid carrying case that closes the air hole of an air battery by attaching a positive electrode of the air battery to a magnetic rubber plate having a soft surface and prevents discharge of the air battery when the hearing aid is not used ( For example, see Non-Patent Documents 1 and 2).

It is desirable to carry a spare battery on a daily basis since the electric capacity of an air battery used by a small hearing aid is small and its operation end time is difficult to predict. Therefore, a hearing aid carrying case is provided in which a spare air battery can be fixed and stored on a magnetic rubber plate.

In order to solve the above-mentioned problems, a hearing aid carrying case according to the present invention has a case body formed of a container portion and a lid portion, and a buffer adapted to accommodate a plurality of shapes of a small hearing aid and an air battery for the hearing aid in the case body. Equipped with a pad for use. The shape of the case body composed of the container part and the lid part corresponds to the shape and number of hearing aids to be accommodated, the number of air batteries to which the shape of magnetic rubber is stuck, and a dome-shaped soft to fix them to the lid part It is equipped with a flexible cushioning pad that forms a cushion.

The hearing aid carrying case according to the first aspect of the present invention includes a cushioning pad having a shape in which a case body is formed from a container portion and a lid portion, and a magnetic rubber for adhering a plurality of air batteries for hearing aids is included in the case body. It is characterized by that. According to the first aspect of the present invention, in the hearing aid carrying case, the cushioning pad is attached only to the lid portion, but the cushioning pad to which the magnetic rubber for bonding the hearing aid and the air battery having different shapes is attached to the container portion.

The hearing aid carrying case according to the second aspect of the present invention has a case body formed of a container portion and a lid portion, and a portion for mounting a magnetic rubber on the lid portion with a flexible cushioning pad that can accommodate a plurality of shapes of a small hearing aid. It is characterized by having a buffer pad of the container part.

According to the present invention , the natural discharge of the air battery cannot be prevented unless the air hole in the positive electrode of the air battery is blocked regardless of whether the hearing aid is activated. There is literature that encourages the reuse of the sticker that was previously attached to the positive electrode when you purchased an air battery, but it is difficult to store such a small seal, and it can be sealed by multiple use. The adhesive strength of is lost. The spontaneous discharge prevention by attaching the positive electrode of the air battery of the present invention to the magnetic rubber can reduce the voltage drop of the air battery semipermanently without reducing the adhesive force because the electrode is made of a magnetic material. (See Non-Patent Document 3).

The first invention relates to the discharge characteristics of the air battery, but since the voltage of the discharge characteristics of the air battery decreases rapidly, a spare battery is used for the hearing aid driven by the air battery. It is recommended. Since magnetism permeates through paper and plastic, the air battery at the time of purchase is directly attached to the magnetic rubber, so that the battery in use and the new battery can be stored and carried at the same time while preventing spontaneous discharge (Non-patent Document 2). reference).

The structure of the hearing aid carrying case according to the second aspect of the present invention can be adapted to the three shapes of the ear-shaped hearing aid, which is a typical example of a small-sized hearing aid, and can be accompanied by several air batteries. The shape of the ear hole type hearing aid is several times larger than the size of the hearing aid as illustrated in FIG. The three shapes of 100 full shell, 200 canal, and 300 minicanal in FIG. 1 depend on the shape of the outer ear of the hearing aid wearer and which one the hearing aid wearer chooses. In addition, as hearing loss increases, the suitable hearing aid changes from a minicanal shape to a full shell shape, and the shape increases. Since the hearing loss of a hearing aid wearer often increases with age, the wearer of a minicanal hearing aid often becomes a full-shell hearing aid wearer. By adopting the hearing aid carrying case of the present invention, such a person can also use the conventional one without newly making a new hearing aid carrying case. 101 described in the three types of hearing aids 100, 200, and 300 in FIG. 1 is a portion inserted into the ear canal, and 102 is a portion of a battery holder.
