Description

本発明は、義歯などの研削作業時に発生する粉塵が周囲に飛び散るのを防止することができる訪問歯科診療用簡易防塵容器に関するものである。 The present invention relates to a simple dustproof container for visiting dental practice that can prevent dust generated during grinding operations such as dentures from scattering around.

世界に先駆けて日本は超高齢社会に突入し、その結果、寝たきりの要介護者が急増している。寝たきり患者の死亡原因の第一位となっている誤嚥性肺炎を予防するために、最近、口腔衛生の強化や摂食嚥下障害のリハビリテーションに社会的関心が非常に高まってきている。また、安易な胃瘻に頼ることなく、自らの口で食事がとれるようになると、その喜びは患者に前向きな気持ちをもたせ、認知障害の改善や、寝たきり状態であった者がベッドから起き上がり、自らの足で歩き回れるまでに回復することが医学的に証明されてきている。このような背景の下、摂食嚥下障害患者にとってのリハビリテーションの道具として、寝たきり患者の義歯の重要性が日増しに高まってきている。 Japan has entered a super-aged society ahead of the world, and as a result, the number of caregivers who are bedridden is rapidly increasing. Recently, in order to prevent aspiration pneumonia, which is the leading cause of death of bedridden patients, recently, social interest has been greatly increased in strengthening oral hygiene and rehabilitation of dysphagia. Also, when you can eat with your mouth without relying on easy gastrostomy, the joy will make the patient feel positive, improve cognitive impairment, and those who were bedridden get up from bed, It has been medically proven to recover before you can walk around on your own. Under such circumstances, the importance of dentures for bedridden patients is increasing day by day as a tool for rehabilitation for patients with dysphagia.

ところが、寝たきりになると、義歯の不具合に際して歯科医院の受診が困難となり、訪問歯科診療に頼らざるをえなくなる。そのため家庭や老人施設など、歯科診療機器が整備されていない場所での診察が必要となり、医療機材類を直接現場に持ち込む必要性に迫られている。この場合、特にいろいろな疾患を抱え抵抗力の弱い在宅の要介護者が多く、病原菌の外部からの持ち込みや、患者から術者への感染など、設備の整っていない環境での衛生面での注意が求められている。 However, if you are bedridden, it will be difficult to visit the dental clinic if your denture is defective, and you will have to rely on visiting dental care. For this reason, medical examinations are required in places where dental care equipment is not available, such as homes and elderly facilities, and there is a pressing need to bring medical equipment directly to the site. In this case, there are many care recipients who have various diseases, especially at home, and have low resistance. In terms of hygiene in an unequipped environment, such as bringing in pathogenic bacteria from the outside or infection from the patient to the surgeon. Attention is required.

訪問歯科診療では、治療の８割が義歯関連である。具体的には、旧義歯の診療にあたって、噛み合わせに関係する咬合面の調整や、口腔粘膜に接する義歯床粘膜面の調整や裏装が必要となってくる。また、維持安定のために義歯床外形の形態修正も必要となる等、いずれも患者の旧義歯を削除修正する必要があり、臨床の現場では歯科技工用エンジン（マイクロモーター）が多用されている。 In visiting dental practice, 80% of treatment is related to dentures. Specifically, in the treatment of old dentures, adjustment of the occlusal surface related to biting, adjustment of the denture basement mucosa surface in contact with the oral mucosa and lining are required. In addition, it is necessary to modify the shape of the denture base shape for maintenance and stability, and it is necessary to delete and modify the patient's old dentures. Dental engine engines (micromotors) are frequently used in clinical settings. .

訪問歯科診療では、歯科技工用エンジンで義歯を削除すると、義歯床の削り屑が家庭内の周囲に飛び散るために、治療後には周辺の掃除が必要となる。在宅での義歯調整にあたって、歯科技工用エンジンで義歯を削除すると、周囲を削り屑で汚すにとどまらず、さまざまな疾患を抱えた要介護者が多いため不潔な義歯が多く、削り屑に付着した感染源を周囲にまき散らすことにもなる。これを最小限に留めるため、集塵装置として家庭用の掃除機を一時借用する場合や、専用の集塵装置として持ち運びが可能な小型のボックスタイプがあり、それには繰り返し使用できるものや使い捨てのものがある。 In visiting dentistry, if a denture is deleted by a dental technician engine, the denture base shavings scatter around the home, so that the surroundings must be cleaned after treatment. When adjusting dentures at home, if the dentures were deleted with the engine for dental technicians, not only the surroundings were soiled with shavings, but there were many unclean dentures because there were many care recipients with various diseases, and they adhered to the shavings It will also spread the source of infection around. To minimize this, there is a small box type that can be used as a dust collector, or a small box type that can be carried as a dedicated dust collector. There is something.

ボックスタイプのものでは、歯科技工用エンジンに連結しているハンドピースと義歯を同時に容器内に入れ、削り屑が周囲に飛び散らないように容器内で切削するようになっている。たとえば、下記特許文献１に開示されているような組み立て式防塵ボックスが知られている。この組み立て式防塵ボックスは、天板と正面板と背面板と底面板と一対の側板とが一枚の透明なプラスチック製シートから形成されており、折曲線で折曲させることでコンパクトに折り畳むことができ、折り畳んだ状態から、側板の背面板係止用差込片を背面板の背面板差込口に差し込むと共に、側板の底面板係止用差込片を底面板の底面板差込口に差し込むことで組み立てることができる。 In the case of the box type, a handpiece and a denture connected to a dental engine engine are simultaneously placed in a container and cut in the container so that shavings do not scatter around. For example, an assembly-type dustproof box as disclosed in Patent Document 1 below is known. In this assembled dustproof box, the top plate, the front plate, the back plate, the bottom plate, and the pair of side plates are formed from a single transparent plastic sheet. From the folded state, insert the back plate locking insert of the side plate into the back plate insertion port of the back plate, and insert the bottom plate locking insert of the side plate into the bottom plate insertion port of the bottom plate. It can be assembled by plugging in.

しかしながら、特許文献１に開示されるような組み立て式防塵ボックスでは、使い捨てとする場合、廃棄にあたっては小さく折りたたむ必要があり、その際にボックス内の削り屑が一対の側板に形成された開口部から外部にこぼれ出て、周囲を汚染することが多い。また、使い捨てとすることは衛生的である反面、コストが非常に高くつくという欠点がある。 However, in the assembly-type dustproof box as disclosed in Patent Document 1, when it is disposable, it is necessary to fold it down for disposal. At that time, the shavings in the box are opened from the openings formed in the pair of side plates. Often spills out and pollutes the surroundings. In addition, although disposable is hygienic, it has a drawback that the cost is very high.

通常、訪問歯科診療は、複数の訪問先を連続して訪問するので、繰り返し使用する場合には、次の訪問先を訪問する前に、容器内の削り屑を廃棄しなければならない。これは、汚染物である削り屑をそのまま別の訪問先に持ち込むことになってしまうからである。特許文献１に開示された組み立て式防塵ボックスでは、内部の削り屑を廃棄する際に展開する場合、その展開時に内部の削り屑が周囲に飛散するおそれがある。展開せずに側板の開口部から廃棄する場合には、その開口部まで削り屑を移動させる手間がかかる。廃棄後においてボックス内に削り屑が残っている場合、その残った削り屑を、側板の開口部から挿入した清掃具などを用いてかき集めて前記開口部から取り出すことになり、削り屑が取り出しにくい。また、展開して廃棄する場合、または開口部から廃棄する場合であっても、ボックス内部からゴミ箱などに削り屑を直接に廃棄する手間がかかり面倒である。 In general, visiting dental care visits a plurality of visits consecutively, and therefore, when used repeatedly, shavings in the container must be discarded before visiting the next visit. This is because the shavings that are contaminants will be brought directly to another visit. In the assembly-type dustproof box disclosed in Patent Document 1, when the internal shavings are deployed when the internal shavings are discarded, the internal shavings may be scattered around during the deployment. When discarding from the opening of the side plate without unfolding, it takes time and effort to move the shavings to the opening. When scraps remain in the box after disposal, the scraps are collected by using a cleaning tool inserted from the opening of the side plate and taken out from the opening, making it difficult to remove the scrap. . Moreover, even when unfolding and discarding or discarding from the opening, it is troublesome and troublesome to discard the shavings directly from the inside of the box to a trash box or the like.

本発明は、このような問題に鑑みてなされたものであり、その主たる目的は、義歯などの切削作業で発生した削り屑の廃棄時において、外部への削り屑の飛散を抑制しつつ容易に削り屑を廃棄することができる訪問歯科診療用簡易防塵容器を提供することにある。また、衛生的かつ経済的な訪問歯科診療用簡易防塵容器を提供することにある。 The present invention has been made in view of such a problem, and its main purpose is to easily prevent scattering of swarf to the outside during disposal of swarf generated in cutting work such as a denture.
