Description
【０００１】[0001]
本考案は、歯科治療に用いられる充填物などの医療用材料を硬化させるためな どに好適に実施することができる医療用光照射装置に関する。 The present invention relates to a medical light irradiation device that can be suitably implemented for curing medical materials such as fillers used for dental treatment.
【０００２】[0002]
先行技術として、たとえば実開平２−１３１４１６（実公平５−３０４２８） 号公報がある。この先行技術では、光重合によって硬化する歯科治療用材料に光 を照射するための光照射用ハンドピースが開示されており、このハンドピースは 、光源を備えるハンドピース本体と、この本体に着脱自在に装着される充電池と を備える。 As a prior art, there is, for example, Japanese Utility Model Laid-Open No. 2-131416 (Japanese Utility Model Publication No. 5-30428). This prior art discloses a light irradiation handpiece for irradiating a dental treatment material that is cured by photopolymerization with light. The handpiece includes a handpiece body including a light source and a detachable body. And a rechargeable battery attached to the.
【０００３】 このような先行技術では、光の照射時間が長い場合、単一の充電池だけでは電 力容量が小さいため、長時間にわたる光照射は不可能であるという問題を有する 。In such a prior art, when the light irradiation time is long, there is a problem that the light irradiation is impossible for a long time because the power capacity is small with only a single rechargeable battery.
【０００４】 また他の先行技術は、たとえば特開平５−３３７１４号公報に開示されている 。この先行技術では、光照射用ハンドピースに接続コードを介して電力を供給す るようにした構成が開示されているけれども、このような接続コードがたとえば 、長時間にわたって光を照射することは可能であるけれども、接続コードが邪魔 になって、操作性が悪いという問題が生じる。Another prior art is disclosed in, for example, Japanese Patent Laid-Open No. 5-33714. Although this prior art discloses a configuration in which power is supplied to the light irradiation handpiece through a connection cord, such a connection cord can irradiate light for a long time, for example. However, the connection cord gets in the way, causing a problem of poor operability.
【０００５】 さらに他の先行技術として、複数の充電池を並んで立設するように挿入するこ とができる２つの凹所を有する充電装置が周知である。この先行技術では、各凹 所に充電池をそれぞれ収納することはできるけれども、充電することができるの は一方の凹所に挿入された充電池だけであり、他方の凹所に挿入された充電池に は、充電することはできず、したがって一方の充電池の電力を消費したときに他 方の充電池に交換すれば良いけれども、この他方の充電池が充分に充電されてい ない状態では、充分な光強度で光を照射することは不可能である。したがって少 なくとも一方の充電池が充分に充電されるまで光を照射することはできず、治療 が中断してしまうおそれがある。As still another prior art, a charging device having two recesses into which a plurality of rechargeable batteries can be inserted so as to stand side by side is known. In this prior art, each rechargeable battery can be stored in each recess, but only the rechargeable battery inserted in one recess can be charged and the rechargeable battery inserted in the other recess can be charged. The battery cannot be recharged. Therefore, when the power of one rechargeable battery is consumed, it can be replaced with the other rechargeable battery, but if the other rechargeable battery is not fully charged, It is impossible to irradiate with sufficient light intensity. Therefore, at least one of the rechargeable batteries cannot be irradiated with light until it is fully charged, which may interrupt the treatment.

Become. In this way, since the rechargeable battery can be attached to the body of the handpiece and the power of the rechargeable battery can be supplied to the body at the same time, the time and effort for connecting the electrodes can be saved and the convenience is improved.
【００２８】 また本考案によれば、充電装置の各凹所は、装着された充電池およびホルダ部 がほぼ垂直に立設するように形成されているので、充電池を充電装置の各凹所に 装着し、または抜き取るにあたってその軸線方向に沿って上方へ引き抜き、また は軸線方向に沿って下方へ挿入すればよく、各充電池の充電装置への着脱作業を 容易かつ円滑に行うことが可能である。Further, according to the present invention, since each of the recesses of the charging device is formed so that the mounted rechargeable battery and the holder portion are erected substantially vertically, the rechargeable battery is installed in each recess of the charging device. When installing or removing the rechargeable battery to or from the battery charger, it is possible to easily pull out the rechargeable battery from or attach it to the battery charger, and pull it out upward along the axial direction or insert it downward along the axial direction. Is.
【００２９】 また本考案によれば、充電装置の各凹所には、掃除用の開口部が設けられるの で、凹所内に侵入した埃などを介して容易に外部へ排出することができ、各凹所 内の充電用電極に埃などが付着して接触不良などを生じることを可及的に少なく することができるとともに、アルコールを使って払拭し消毒することができるた め、凹所を衛生的に保つことができる。Further, according to the present invention, since each recess of the charging device is provided with an opening for cleaning, it is possible to easily discharge dust or the like that has entered the recess to the outside, It is possible to minimize the possibility of contact failure such as dust adhering to the charging electrode inside each recess, and it is possible to wipe and disinfect with alcohol to clean the recess. It can be kept hygienic.
