Description

本発明は、耳鼻咽喉科、歯科などにおいて、医師が診察や治療を行う際に、診察椅子に腰かけた患者の体内の奥深い患部を反射鏡で反射して光を照射するときに使用される医用照明装置に関するものである。   The present invention is a medical device used in otolaryngology, dentistry, etc., when a doctor examines or treats and irradiates light by reflecting a deeply affected part of a patient sitting on an examination chair with a reflecting mirror. The present invention relates to a lighting device.

耳鼻咽喉科で、耳孔の奥、鼻孔の奥、喉の奥などの患部に光を照射し、また、歯科で奥歯に光を照射し、診察したり、治療したりするとき、図１０に示すように、医師１１が額から後頭部に巻きつける額帯１５に反射鏡１６を取り付け、光源１７からの光線を反射して患部を照射する。この光源１７は、複数本のアームを関節で連結し、全方向に移動できるように構成されており、患者１０は、診察椅子１２に座って背中を背もたれ１８に密着し、頭部１４を支頭部１３に密着したとき、患部の位置によって最も光線が通るように医師１１は、光源１７の位置や向きを変え、反射鏡１６ののぞき孔１９から覗き込んで治療や診察をする（特許文献１）。   In otolaryngology, when the affected part such as the back of the ear canal, the back of the nostril, the back of the throat, etc. is irradiated with light, and the back tooth is irradiated with dentist for examination and treatment, it is shown in FIG. As described above, the reflecting mirror 16 is attached to the forehead 15 wound around the back of the head from the forehead, and the affected part is irradiated by reflecting the light beam from the light source 17. The light source 17 is configured so that a plurality of arms are connected by joints and can move in all directions. The patient 10 sits on the examination chair 12, has his back closely attached to the backrest 18, and supports the head 14. When closely attached to the head 13, the doctor 11 changes the position and orientation of the light source 17 so as to pass the light most depending on the position of the affected part, and peeks through the viewing hole 19 of the reflecting mirror 16 for treatment and diagnosis (Patent Document). 1).

また、額帯の前額部の反射鏡の焦点位置に、光源としての電球を内蔵させたものも知られている（特許文献２）。   Further, there is also known one in which a light bulb as a light source is incorporated at the focal position of a reflecting mirror in the forehead portion of the frame (Patent Document 2).

特開２００１−３２７５５９号公報JP 2001-327559 A 実用新案登録第３０３１５７４号公報Utility Model Registration No. 3031574

特許文献１に記載の発明は、医師１１は、のぞき孔１９から患部を覗き込みながら患部の位置によって最も光線が通るように光源１７の位置や向きを変えて調整するが、この調整は、光源１７が患者１０の背後にあるので、患者１０が立ち上がるときに光源１７に頭部１４をぶつける恐れがあること、医師１１が片手で光源１７を支持しているアームを伸縮したり、角度を変えたりすることによって光線の調整行うため、片手が使用できなくなり、両手で行う治療や診察に支障をきたしていたこと、光源１７が主として白熱電球を使用していたため、患者１０，医師１１共に光源１７の発熱で熱いこと、光源１７を支持する支持台、複数本のアーム、アーム同士を連結する関節部分などの装置が大型になり、高価なものとなっていたこと等の問題があった。   According to the invention described in Patent Document 1, the doctor 11 adjusts the light source 17 by changing the position and orientation of the light source 17 so that the light beam passes most depending on the position of the affected part while looking into the affected part from the viewing hole 19. Since 17 is behind the patient 10, there is a risk that the head 14 may hit the light source 17 when the patient 10 stands up, and the doctor 11 can extend and contract the arm supporting the light source 17 with one hand or change the angle. Since the light beam is adjusted by using the light source 17, one hand cannot be used, which has hindered the treatment and examination performed with both hands, and since the light source 17 mainly uses an incandescent bulb, both the patient 10 and the doctor 11 use the light source 17. It was hot due to the heat generated, the support base for supporting the light source 17, a plurality of arms, the joint part for connecting the arms to each other became large and expensive. There was a problem.

特許文献２に記載の発明は、前額部の反射鏡の焦点位置に小さな電球を内蔵させたものであるため、光量不足になり易く、また、電源として乾電池を使用する場合、その乾電池を頭部に載せるように収納すると、医師１１に取って作業の邪魔になり、更に、電池切れなどが発生する。大型の電源から電力を供給すると、電池の容量不足や電池切れなどはないが、電源と電球を接続するコードが医師１１の作業の邪魔になる等の問題があった。   Since the invention described in Patent Document 2 has a small light bulb built in the focal position of the reflector on the forehead, the amount of light tends to be insufficient, and when a dry battery is used as a power source, If it is stored so as to be placed on the part, it will be obstructed by the doctor 11 and work will be interrupted, and the battery will run out. When power is supplied from a large power source, there is no shortage of battery capacity or battery exhaustion, but there is a problem that the cord connecting the power source and the light bulb interferes with the work of the doctor 11.

本発明は、特に人間の頭部の耳、鼻、咽喉、歯などの患部に光を照射して診察したり、治療したりするときに有効な医用照明装置を提供することを目的とするものである。   It is an object of the present invention to provide a medical lighting device that is particularly effective when irradiating light to an affected area such as the ear, nose, throat, and teeth of a human head for diagnosis and treatment.
