Description

  The present invention relates to a take-out device for easily exchanging an acoustic damper of a custom-made hearing aid.

  The custom-made hearing aid has a sound output receiver for sound output and a thin sound path rubber tube that transmits the sound by connecting the shell mouthpiece. Inside the sound path rubber tube, the inner diameter is about 1 mm to adjust the acoustic characteristics. A small basket-shaped acoustic damper is included, which becomes dirty with earwax and moisture during use and decreases the sound output, and there is a dustproof filter in the sound outlet, but fine dust and moisture in the inner ear are This dirty acoustic damper that accumulates on the acoustic damper that passes through is taken out and replaced with a new one, and sometimes it is also replaced when checking after-sales service. Although the above work is quite simple, the protrusion is connected to the inner surface of the acoustic damper, but the inner surface of the acoustic damper and the tip of the needle tip are not. It does not bite well, the acoustic damper rotates sideways, the tip of the tip of the needle tip protrudes from the acoustic damper, the tip of the protrusion cracks on the side of the sound path rubber tube, and the sound is heard during overlapping operations. Even if the damper enters the back of the sound path rubber tube and the operation of a slight force is applied, the sound path rubber tube terminal may come off from the connection part of the receiver, and the sound path rubber tube is cracked as shown above. If the instrument is unfingered or unentrained, howling may occur in the output sound or proper sound quality may not be gained. This (removing the outer part), removing all the content parts and replacing the sound rubber tube, is inconvenient for the wearer during the storage period and is expensive. .

  The conventional acoustic damper take-out operation shown in FIG. 13 is performed by picking the hearing aid body shell 26 upward with the fingertip of one hand and folding the injection needle tip 36 of the injection needle 35 to form the injection needle protrusion 36a. Pick the syringe connection part 37 with the thumb and index finger of the other hand of the injection needle 35, insert the needle tip part 36 from the sound opening 31 of the hearing aid, and inside the fine acoustic damper 27 in the thin sound path rubber tube 30 The needle tip protrusion 36a is hooked on the side connection point g, and the acoustic damper 27 is taken out while pulling up the hand holding the syringe connection portion 37. At this time, since the connection corresponding point is one point of g point, The connection with the damper does not work well, the acoustic damper 27 turns sideways, the tip of the protrusion 36a drops off from the connection point g, and the tip of the protrusion cracks the side of the sound path rubber tube. Needle tip during redo Due to the slight stress of 36, the end portion 30a of the sound path rubber tube 30 is untangled from the connection portion 29 of the sound output receiver 28 as shown in the diagram of 30b, and the damper 27 is sounded as shown in the diagram of 27a. The rubber pipe ends out of the end of the road rubber pipe, so that repair at the store cannot be performed, and the repair becomes a serious problem as shown in the preceding paragraph 0002.

  In the replacement of the acoustic damper using the conventional injection needle described above, a serious trouble as described above is sometimes encountered while burdening an excessive nerve during the replacement operation.

  The present invention can be used to remove the acoustic damper in the sound path rubber tube as described above, in a little work, and to have the acoustic damper rotate sideways in the sound path rubber tube, or to the crack or sound output receiver in the sound path rubber tube. The purpose is to make it possible to easily take out and replace the acoustic damper without causing a serious trouble such as unwinding.

Means for Solving the Invention

  In order to solve the above-described problems, the present invention provides that the tip of the needle is placed on the inner surface of the acoustic damper so that the tip of the tip does not apply an extra pressure to the sound path rubber tube in the operation of taking out the acoustic damper. In order to ensure a firm connection, the ultra-high-angle projections that contact the inner surface of the acoustic damper are made into thin needle-like shapes so that the coupling action point between the inner surface of the acoustic damper and the projection of the needle tip is two diagonal points. Formed outward on the outer side of the tip of the right and left arm members and paired forward from the handle member to the inner side of the right and left handles of the handle member that is picked by the two fingertips of the thumb and index finger A pair of hinge members are connected to each other so as to overhang, and the projections are evenly movable and securely connected to the two points on the inner side surface of the acoustic damper, so that the acoustic damper is accurately fitted from within the sound path rubber tube. Easy removal of the acoustic damper That.

  If the right and left arm members shown above are projected horizontally and straight from the handle, the state of the tip of the arm that operates inside the sound path rubber tube is obstructed by the fingertip that is operated, which hinders the work. Therefore, an approximately L-shaped downward curve is provided in the middle of the arm member to improve the line of sight and facilitate the work.

  The acoustic damper to be taken out is an extremely small part with an inner diameter of about 1 mm knitted in a bowl shape, and is inserted into a thin sound path rubber tube, so that the thin sound path rubber tube and the inner surface of the sound damper can be freely moved forward and backward. In addition, the needle-shaped right and left arm members shown in the above-mentioned about the inverted L-shaped downwardly bent portion from the downward curved portion have an inner side surface that is extremely flat, and the flat inner side surfaces are joined to each other. The side surface is formed into a chopstick-shaped chopstick shape toward the tip, facilitating stress adjustment and operability at the arm tip of the acoustic damper take-out device.

  The right and left protrusions shown in the paragraph 0008 are formed so that the dimensions between the right and left protrusion tips are slightly narrower than the inner diameter of the acoustic damper when the right and left arm tips are in contact with each other. The slope of the ridge line connecting the arm tip and the right and left projection tips is formed in the shape of an arrow-shaped receding angle with the right and left arm tips in contact with each other, inside the sound path rubber tube and the acoustic damper. Allow the side to enter freely.

  On the inner side surface of the rear part of the right handle member and left handle member shown in the above-mentioned paragraph 0006, circular spring fitting recesses for fitting the spring member are provided correspondingly, and the right and left arm tip parts shown above Is normally closed, and a spring member adapted for operation of the acoustic damper take-out device is fitted into the right and left spring fitting recesses to facilitate the operation.

  The damper take-out device shown in the above-mentioned paragraph 0006 has a circular concave grip portion for fitting the fingertips on the outer side surfaces of the right and left handle members, and an appropriate position slightly behind the hinge shaft center shown above. To facilitate the work of taking out a fine acoustic damper.

The invention's effect

  The acoustic damper take-out device of the present invention has a pair of protrusions in contact with two diagonal points on the inner side surface of the acoustic damper to be taken out at a pair of minute acute angles on the outer side of the tip of the thin needle-like arm member. A pair of hinge members that can be opened and closed facing each other and the rear part of the arm member are arranged vertically on the side surface of the inner front part of the handle member that is picked by the fingertips of the handle member, and the protrusions are formed by closing the handle member with the fingertips. Moves toward the inner surface of the acoustic damper, and engages and connects with the inner surface of the acoustic damper. The acoustic damper is turned sideways in the thin acoustic rubber tube, or the acoustic damper that is taken out from the pair of arm tip protrusions falls off the sound path. Eliminates serious troubles such as damage to the rubber tube or excessive load on the sound path rubber tube, causing the sound path rubber tube connection to unwind from the receiver connection. .

  If the arm member that constitutes the protruding portion protrudes in a straight line from the handle member, the line of sight of the arm tip is obstructed by the operation fingertip, so it protrudes in pairs from the handle tip and bends inward in the opposite direction. Bend around the reverse L-shape at the joined point to avoid line-of-sight obstacles, and make the inner side surfaces of both arm members super flat from the lower bent part to make a chopstick-shaped chopsticks toward the tip. Thinly formed to improve the precise operation inside the narrow sound path rubber tube, while preventing the change in the shape of the thin arm member and strengthening the torsional stress at the arm tip.

  The protrusion formed on the outer side of the arm tip shown in section 0012 may bend the thin needle tip, but it is easy to process with a soft material but has no response, and heat treatment with a hard material. The tip of the needle tip will be damaged if it is not bent, and the bending process in heat treatment will keep the size and shape of the protrusion constant and ensure the strength of the bent portion even if the ultrafine protrusion is bent. If the projections formed on the outer side of the outer side of the needle-shaped arm, which is difficult to grind, are ground from the shape like the inner side of the doughnut to form a micro-acute projection, the projection for the acoustic damper removal operation The anti-damage effect could be improved while strengthening the bonding force to the two points on the inner surface of the acoustic damper.

  The pair of right and left tip ridges connecting the tip of the projection and the tip of the arm shown above are formed in an arrow shape so that the tip of the arm when the acoustic damper is taken out is connected to the inner surface of the sound path rubber tube and the acoustic damper. The insertion-inhibiting factor was successfully avoided.

  In order to control the movable adjustment stress at the tip of the protrusion shown in the item 0012, a spring member that mixes elastic force is formed at the rear part of the handle part to improve the operation performance of the acoustic damper take-out device.

  Since the acoustic damper is fine, the acoustic damper is taken out by forming a circular concave finger grip that is easy to pick with the fingertip on the outer side surface of the handle member slightly behind the fixing position of the hinge member provided on the handle member. The precise operation with the fingertips was facilitated.

  As shown above, the handle member of the acoustic damper take-out device is formed by bending and bending the arm member rear end portion to form a handle, and a box in which a spring member is fitted to the rear end portion is formed facing each other. A spring member is fitted in the fitting box, and a cup-shaped finger grip that fits the fingertip is formed slightly behind the side surface of the hinge member with the base facing outward, and the acoustic performance is the same as that of the acoustic damper take-out device. A damper ejector was constructed.

  If an ultra-compact LED lamp that illuminates the tip of the arm is configured at the front end of the acoustic damper take-out device shown in the preceding paragraphs 0012 to 0017, the tip of the arm is clearly inserted in the operation of inserting the tip of the arm in the sound path rubber tube.
