Description

Ear-worm planting device

Technical Field

The invention belongs to the field of artificial cochlea, and particularly relates to an implanted cochlea device.

Background

Artificial cochlea (also called bionic ear, electronic cochlea, cochlear implant) is an implanted hearing aid device, whose function is to make a patient with severe hearing loss (deaf person) produce a certain sound perception. Unlike other types of hearing aids, such as hearing aids, the principle of operation of the cochlear implant is not to amplify sound, but rather to apply pulsed electrical stimulation to the auditory nerve that is within the cochlea and is still functioning well. Most cochlear implant devices consist of an implanted portion and an extracorporeal portion. The extracorporeal portion is composed of a microphone, a voice processor and a signal transmitter for transmitting instructions to the implanted portion. The implantation part consists of a signal receiving and decoding module and a stimulating electrode array.

The existing artificial cochlea has the following problems in the use process:

the speech processor and the signal transmitter are electrically connected through a data wire which is spliced and matched with the speech processor and the signal transmitter, and the position of the splicing joint of the data wire and the speech processor and the signal transmitter is electrically corroded or the guiding performance of the speech processor and the signal transmitter is influenced by entering dust.

The battery plug in the speech processor of the artificial cochlea can be subjected to electric corrosion or the power supply stability of the battery is influenced by entering dust due to long-term use, and the unstable power supply of the battery can cause current pulse, so that a chip is damaged.

The headset hole of the speech processor is often blocked due to dust, and the blocked headset hole can seriously lead to the effect that the internal vibrating membrane receives sound, so that the conversion module is influenced to effectively convert the sound signal into an electric signal.

The invention designs an embedded ear worm device which solves the problems.

Spring a17 is a compression spring.

The implant 54, the transmission module 50 and the plug-in unit of the present invention are all conventional.

The working flow of the invention is as follows: in the initial state, the transmission module 50 is electrically connected with the external hanging machine, and the two plugging mechanisms B45 are respectively plugged and matched with the plugging mechanism A34 on the transmission module 50 and the plugging mechanism A34 on the external hanging machine. The spring C44 in the plugging mechanism a34 is in a stretched state, and the pins 38 in the plugging mechanism a34 are inserted into the corresponding copper sleeves B48 on the corresponding plugging mechanisms B45. The power module 55 is inserted into the slot A4 on the external device and is in a state of supplying power to the external device. The two springs B27 in the power module 55 are in a compressed state, and the two copper contacts 32 are respectively in electrical contact with the corresponding copper contact plates 18 and elastically bent to some extent. The cleaning block 52 on the swing rod 11 in the outer hanging machine is at a certain distance from the headset hole 5, the triggering block 12 protrudes out of the side wall of the outer hanging machine, the spring A17 is in a compressed state, the vortex spring 15 is in a compressed state, and the swing rod 11 is propped against the side walls of the swing groove B13 and the swing groove A8 under the action of the vortex spring 15 and is in a state vertical to the triggering block 12.

When the earphone of the invention is used for a period of time, the earphone hole 5 is blocked due to the accumulation of dust, and at the moment, the earphone hole 5 can be effectively cleaned only by pressing the trigger block 12 back and forth.

When the trigger block 12 is pressed, the trigger block 12 compresses the spring A17, the swing rod 11 swings around the swing pin A14 towards the headset hole 5 under the action of the swing groove A8, the two volute springs 15 are further compressed, and the swing rod 11 drives the cleaning block 52 to be inserted into the headset hole 5 and effectively cleans dust and dirt accumulated in the headset hole 5. When the pressing force on the trigger block 12 is removed, the trigger block 12 is reset instantly under the reset action of the spring A17, and the swing rod 11 drives the cleaning block 52 to swing back and reset under the reset action of the volute spring 15.

If corrosion is generated between two copper contact pieces 32 and corresponding copper contact plates 18 in the power module 55 according to the invention, the power module 55 can be plugged and unplugged to effectively clean the corrosion generated between the copper contact pieces 32 and the copper contact plates 18.

In the process of inserting the power module 55 into the slot A4, the two copper contact plates 32 in the straight plate state interact with the corresponding copper contact plates 18 respectively, the copper contact plates 32 slide relatively on the contact surfaces of the corresponding copper contact plates 18 and deform in a self-adaptive manner, the relative sliding generated by the copper contact plates 32 and 18 can effectively scrape out the electric corrosion generated on the contact surfaces of the copper contact plates 32 and 18, most of the fallen corrosion falls into the net-shaped collecting shell 33 on the side surfaces of the copper contact plates 32 to be collected, and a small part of the corrosion falls onto the power supply seat 19.

During the process of pulling the power module 55 out of the slot A4, the two copper contacts 32 gradually disengage from the corresponding copper contacts 18 and gradually return to the straight state. When the power module 55 is completely pulled out of the slot A4, the rust in the two collecting shells 33 and falling onto the power seat 19 can be effectively cleaned by the blower. If part of the rust in the collecting shell 33 is adhered to the inner wall of the collecting shell and is not easy to clean by blowing, at this time, one of the arc plates 31 can be pressed by hand, the arc plate 31 drives the swing rod 11 to swing around the swing pin B29, the two leaf springs are correspondingly deformed, one sliding block 25 slides outwards of the copper sleeve A23 under the action of the corresponding spring B27 and keeps electrical contact with the arc plate 31, and the other sliding block 25 slides inwards of the copper sleeve A23 under the action of the corresponding spring B27 and keeps electrical contact with the corresponding arc plate 31.

When the arc plate 31 is pressed to the limit, the arc plate 31 is released instantaneously, the swing rod 11 drives the two arc plates 31 to swing back and vibrate under the reset action of the plate spring, the two sliding blocks 25 keep electrical contact with the arc plate 31 all the time along with the swing of the arc plate 31 under the action of the corresponding spring B27, and rust, which is attached to the collecting shell 33 and is difficult to clean, can be effectively separated by the arc plate 31 due to the generated vibration, so that the rust attached to the collecting shell 33 is effectively cleaned.

When the copper contact pads 32 and the copper contact pads 18 are cleaned by the electric corrosion and rust, the power module 55 is reinserted into the slot A4, and the two copper contact pads 32 on the power module 55 inserted into the slot A4 are elastically bent and respectively kept in good electrical contact with the corresponding copper contact pads 18.

If corrosion occurs between the contact pin 38 in the plug mechanism A34 and the copper bush B48 in the plug mechanism B45 due to electric corrosion during long-time operation, the plug mechanism B45 is pulled out of the plug mechanism A34, so that the contact pin 38 is separated from the copper bush B48. Then, the sliding sleeve 43 on the base 35 of the plugging mechanism A34 is pressed, the sliding sleeve 43 drives the cleaning plate 40 to axially move through the guide rod 42, the cleaning holes 41 of the cleaning plate 40 effectively scrape the electric corrosion on the surfaces of the five pins 38, and the spring C44 is further stretched. When the pressing force on the sliding sleeve 43 is removed, the cleaning plate 40 axially resets under the reset action of the spring C44 and drives the sliding sleeve 43 to reset through the guide rod 42, and the reset of the cleaning plate 40 again scrapes and cleans the surfaces of the five pins 38, so that the electric corrosion and rust on the surfaces of the five pins 38 on the plugging mechanism A34 can be effectively scraped and cleaned after the cleaning plate is reciprocated for a plurality of times.

After the contact pins 38 of the plug-in mechanism A34 are subjected to electric corrosion rust cleaning, the plug-in mechanism B45 is plugged onto the plug-in mechanism A34 in a reciprocating manner, the five contact pins 38 of the plug-in mechanism A34 can effectively clean the inner walls of the corresponding copper sleeves B48 on the plug-in mechanism B45, and rust dust on the cleaned inner walls of the copper sleeves B48 falls into the cap 49.

After the cleaning of the inner wall of the copper bush B48 of the plugging mechanism B45 is finished, the cap 49 is unscrewed again after the removal of falling rust is finished, and finally the plugging mechanism B45 is plugged onto the plugging mechanism A34 again.

In summary, the beneficial effects of the invention are as follows: according to the invention, before the plug-in mechanisms A34 on the plug-in body 53 and the transmission module 50 are in plug-in fit with the plug-in mechanisms B45 at two ends of the data line 51, rust or attached dust formed by electric corrosion on the surface of the upper contact pin 38 can be scraped and cleaned, so that good fit between the plug-in mechanisms A34 and the plug-in mechanisms B45 is ensured, and the conductivity of the plug-in mechanisms is ensured.

The invention can clear dust accumulated in the headset hole 5 of the external hanging body 53 by pressing the trigger block 12, thereby ensuring smoothness of the headset hole 5, ensuring effective receiving of sound by the internal vibrating membrane 10 and effectively converting the sound signal into an electric signal by the internal conversion module 9.

According to the invention, when the power supply seat 19 is installed, the two copper contact plates 32 electrically connected with the anode and the cathode of the battery 22 can scrape and clean rust or dust generated by electric corrosion on the corresponding copper contact plate 18 on the external hanging body 53, so that effective electric connection between the copper contact plates 32 and the corresponding copper contact plate 18 is ensured, and further, the chips in the external hanging body 53 are prevented from being damaged due to current pulses caused by unstable electric connection between the copper contact plates 32 and the copper contact plates 18.
