Description

완전 이식형 인공중이의 무선전력전달장치{Wireless power transmission equipment for totally middle ear implant}Wireless power transmission device for totally middle ear implants

본 발명은 무선전달장치에 관한 것으로서, 보다 상세하게는 완전 이식형 인공중이에서 전원의 공급을 자기 결합을 이용한 무접점 방식의 충전기를 채택하여 사용자가 편리하게 사용할 수 있도록 하는 완전 이식형 인공중이의 무선전력전달장치에 관한 것이다.The present invention relates to a wireless transmission device, and more particularly, to a fully implantable artificial center adopts a contactless type charger using magnetic coupling to supply power from the fully implantable artificial middle ear so that the user can conveniently use it. It relates to a wireless power transmission device thereof.

일반적으로, 인간이 갖는 중요한 감각기관인 귀의 감도저하로 인하여 심한 불편을 안겨주는 장애 현상의 하나인 난청의 경우 대부분의 환자들이 기존의 보청기를 이용하여 청각의 문제를 해결하고 있으나 효과적으로 보청기의 도움을 받는 환자는 전체 난청인구의 약 15%에 불과하다. 그 원인은 경제적인 부담이 문제가 될 수 있지만, 실제로는 기존의 보청기가 가지는 성능상의 문제 때문이다.In general, in the case of hearing loss, which is one of the disorders that cause severe discomfort due to desensitization of the ear, which is an important sensory organ of human beings, most patients solve hearing problems using existing hearing aids, but are effectively assisted by hearing aids. Patients account for only about 15% of the total hearing loss. The reason is that the economic burden may be a problem, but in reality, it is due to the performance problem of the existing hearing aids.

이렇듯, 기존의 보청기는 먼저 음성신호를 전기신호로 변환 후 증폭 및 신호처리과정을 거쳐 다시 음성신호로 변환되므로 왜곡현상이 수반되어 음질이 만족스럽지 못하고 청각역치가 높은 난청자에게 사용하기 위하여 보청기의 이득을 높일 경우 음향 피이드백에 의한 하울링현상이 일어나기 때문에 이득의 제한 폭이 좁아지는 문제가 있다.As such, conventional hearing aids convert voice signals into electrical signals first, and then convert them back into voice signals through amplification and signal processing, which is accompanied by distortion, so that the sound quality is not satisfactory and the hearing aid is used for hearing aids with high hearing threshold. If the gain is increased, the howling phenomenon is caused by the acoustic feedback, so that the limit of gain is narrowed.

이러한, 보청기의 문제를 해결하기 위하여 제시된 방안중에서 이식형 인공중이 시스템(Implant middle ear hearing aid system)은 구조가 간단하면서도 효과적으로 음성신호의 왜곡을 크게 줄여 난청자에게 명료한 음향을 제공할 수 있기 때문에 세계적으로 많이 연구되고 있는 실정이다.In order to solve the problem of hearing aids, the implant middle ear hearing aid system has a simple structure and can effectively reduce the distortion of the voice signal, thereby providing a clear sound to the hearing impaired. The situation is being studied a lot worldwide.

한편, 이식형 인공중이 시스템은 소리에 해당하는 형태의 진동을 트랜스듀서를 사용하여 중이의 이소골 또는 내이 입구에 직접 인가하는 방법으로 난청자가 소리를 들을 수 있도록 해주는 청각보조기이다. 그러므로 이러한 이식형 인공중이는 공기 전도형 보청기의 단점인 음향 피드백에 의한 하울링 현상을 줄일 수 있고, 보다 나은 청음 명료도를 얻을 수 있다.On the other hand, the implantable artificial ear system is a hearing aid that allows the hearing impaired person to hear the sound by applying the vibration of the form corresponding to the sound directly to the ear bone or inner ear opening of the middle ear using a transducer. Therefore, the implantable artificial ear can reduce howling caused by acoustic feedback, which is a disadvantage of the air conduction hearing aid, and can obtain better hearing clarity.

그 동안 이식형 인공중이 시스템은 부분 이식형으로 개발되었다. 왜냐하면 시스템을 모두 체내에 이식할 경우에 발생하는 전력공급문제를 해결할 수 없었으며, 이식할 수 있는 크기로 구현하기가 힘든 문제점이 있었다. 그러나, 현재는 전자공학의 발전으로 인하여 이식할 수 있는 크기의 대용량 충전지의 개발, 그리고 초소형소자(SMD 소자 등)의 부품 소형화가 이루어졌기 때문에 완전 이식형 인공중이가 개발되고 있는 추세이다.The implantable artificial ear system has been developed as a partial implant. This is because the power supply problem that occurs when all the systems are implanted in the body could not be solved, and it was difficult to implement the implantable size. However, the development of large-capacity rechargeable batteries and the miniaturization of components of ultra-small devices (such as SMD devices) have been developed due to the development of electronic engineering.

한편, 완전 이식형 인공중이는 전원(배터리)을 포함한 모든 인공중이 장치를 체내에 이식하는 시스템이다. 이 시스템은 충전지를 사용하여 주기적으로 전력을 공급한다. 그러나 충전지를 체내에 이식하면 기존의 접촉형 충전방식으로는 충전을 할 수 없기 때문에 무선충전방식(무접점 충전방식)을 이용하여 충전해야 하는 것이 중요한 설계요소의 하나이다.On the other hand, a fully implantable artificial middle ear is a system for implanting all artificial middle ear devices including a power source (battery) into the body. The system uses rechargeable batteries to periodically power it. However, when the rechargeable battery is implanted into the body, it cannot be charged using the conventional contact charging method, so it is one of the important design elements to charge using the wireless charging method (contactless charging method).

이에 따라 본 발명은 상기와 같은 종래의 문제점을 근본적으로 해결하기 위한 것으로서, 완전 이식형 인공중이에서 전원의 공급을 자기 결합을 이용한 무접점 방식의 충전기를 채택하여 사용자가 편리하게 사용할 수 있도록 하는 완전 이식형 인공중이의 무선전력전달장치를 제공하려는데 그 목적이 있다.Accordingly, the present invention is to fundamentally solve the conventional problems as described above, by adopting a contactless type charger using a magnetic coupling to supply power in a fully implantable artificial middle ear so that the user can conveniently use The purpose of the present invention is to provide a portable implantable artificial power wireless power transmission device.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 무선전력전달장치의 회로를 나타내는 블록도이고, 도 2는 본 발명에 따른 무선전력전달장치에서 체내이식회로의 배치된 상태를 나타내는 배치도이며, 도 3은 본 발명에 따른 무선전력전달장치에서 송신코일과 수신코일의 구조를 평면과 측면에서 나타내는 구성도이다.1 is a block diagram showing a circuit of a wireless power transmission device according to the present invention, Figure 2 is a layout showing an arrangement state of the body implant circuit in the wireless power transmission device according to the present invention, Figure 3 according to the present invention In the wireless power transfer device, the structure of the transmission coil and the reception coil is shown in plan and side views.

본 발명은 완전 이식형 인공중이에서 체내에 이식된 충전지로 전력의 공급을 하는 무선전력전달장치에 관련된다. 즉, 본원발명의 무선전력절달장치(50)는 기존의 접촉형 충전방식이 아닌 전원의 공급을 자기 결합을 이용한 무선충전방식(무접점 충전방식)으로 구성하여 사용자가 편리하게 사용하도록 한 것이다. 이러한, 무선전력전달장치(50)는 도 1처럼 체내부회로(20)와 체외부회로(30)로 구분된다.The present invention relates to a wireless power transfer device for supplying power to a rechargeable battery implanted in a body in a fully implantable artificial ear. That is, the wireless power delivery device 50 of the present invention is configured to be a wireless charging method using a magnetic coupling (contactless charging method) using a power supply rather than the conventional contact charging method so that the user can use it conveniently. Such a wireless power transfer device 50 is divided into the internal circuit 20 and the external circuit 30 as shown in FIG.

본원발명에 따른 체내부회로(20)는 정류회로(21)와 평활회로(22), 충전회로(23), 충전지(24), 수신코일(25)로 구성된다. 이때, 충전지(24)는 도 2에 도시된 바와 같이, 신호처리회로(26)와 제어회로(27)에 전력을 공급한다. 이러한 체내부회로(20)는 도 4a처럼 귀 뒤의 측두골(10)에 이식하여 외부에서 보이지 않게 구성된다. 체내부회로(20)는 귀 뒤의 측두골(10)에 이식되는 공간의 제약이 있기 때문에 제약조건에 맞추어 그 크기를 조절하여 제작하는 것이 바람직하다. 또한, 체외부회로(30)는 도 1처럼 변압기(31)와 정류회로(32), 평활회로(33) 및 주파수변환회로(34)와 송신코일(35)로 구성된다. 이러한 체외부회로(30)는 일반 가정용 전원(11)이나 상용배터리(12)를 이용하여 전력을 공급한다.The internal circuit 20 according to the present invention is composed of a rectifying circuit 21, a smoothing circuit 22, a charging circuit 23, a rechargeable battery 24, a receiving coil 25.

The wireless power transfer device 50 uses LC resonance for maximum efficiency in the internal circuit 20. The receiving coil 25 and the transmitting coil 35 are provided with ferrite cores 25b and 35b to increase the magnetic coupling coefficient between the respective coils 25a and 35a. Such ferrite cores 25b and 35b further increase the magnetic coupling coefficient between the coils 25a and 35a. The transmission coil 35 includes a magnet 35c on the circumferential surface of the ferrite core 25b of the reception coil 25 to improve the contact force with the skin. Accordingly, the magnet 35c of the transmission coil 35 pulls the ferrite core 25b of the reception coil 25 so as to be in contact with the skin to allow more efficient power transmission.
