Abstract
Description
本発明は修復材料、歯冠材料、補綴材料、予防材料、支台築造材料、根管材料、接着材料、歯面コート材料等の歯科分野において用いることができる歯科用低粘度組成物が充填されているシリンジ及びその蓋に関する。特にフローアブルコンポジットレジン用のシリンジに関する。The present invention is filled with a dental low-viscosity composition that can be used in the dental field, such as restoration materials, crown materials, prosthetic materials, preventive materials, abutment building materials, root canal materials, adhesive materials, and tooth surface coating materials. The syringe and its lid. In particular, it relates to a syringe for a flowable composite resin.
歯科用低粘度組成物であるフローアブルコンポジットレジンはシリンジ先端部に装着した細いノズルから直接、修復部位に充填操作を行えることから、操作性に優れた材料である。A flowable composite resin, which is a dental low-viscosity composition, is a material with excellent operability because it can be filled directly into a repaired site from a thin nozzle attached to the tip of a syringe.
フローアブルコンポジットレジンの使用時にプラスチック製キャップをシリンジから取外した後、そのシリンジにノズルを装着し、患者の口腔内における修復部位に排出して充填する。使用後は感染予防のため患者毎に使用したノズルを取外して交換する必要がある。そのため、再びプラスチック製キャップをシリンジに螺接して保管するか、又は新しいノズルを装着し、その先端部にキャップをして保管していた。この使用は、１日何回も上記操作を繰り返えされ、使用しないキャップは廃棄物として破棄されていた。
特に参考となる従来技術は存在しない。When the flowable composite resin is used, the plastic cap is removed from the syringe, and then a nozzle is attached to the syringe and discharged and filled into the repair site in the patient's oral cavity. After use, it is necessary to remove and replace the nozzle used for each patient to prevent infection. Therefore, the plastic cap is again screwed into the syringe and stored, or a new nozzle is mounted and the tip is capped and stored. This use was repeated the above operation several times a day, and unused caps were discarded as waste.
There is no prior art to be particularly helpful.
キャップはシリンジ先端部に強く螺接しないと密封性が悪くなり、空気の影響を受けてペーストが変質したり、又はペーストが流れ出たりする等の問題があった。更に、蓋を掴む指が口腔内に入るノズル先端部に触れてしまうため、衛生的に好ましくないこと等の問題点があった。またキャップをチェアユニットや補助台の上に置いた場合、小さい為に見付けにくい状況があった。さらに複数回使用している間に、キャップを落下させてしまうこともある。
従来はシリンジのキャップとノズル先端部に挿入して封鎖するキャップとは材質的にも異なる２種類のものを用いており、ユーザは一方のキャップのみを使用されていた。従来、使用時において蓋の内面に歯科用低粘度組成物が付着して糸引き状になる等の問題があり、解決が望まれていた。If the cap is not screwed strongly to the syringe tip, the sealing performance is deteriorated, and there is a problem that the paste is deteriorated due to the influence of air or the paste flows out. Furthermore, since the finger gripping the lid touches the tip of the nozzle that enters the oral cavity, there is a problem that it is not preferable in terms of hygiene. Also, when the cap was placed on a chair unit or auxiliary stand, it was difficult to find because it was small. Furthermore, the cap may be dropped during multiple use.
Conventionally, two types of caps that are different in material are used for the cap of the syringe and the cap that is inserted into the tip of the nozzle and sealed, and the user has used only one of the caps. Conventionally, there has been a problem that a dental low-viscosity composition adheres to the inner surface of the lid during use and becomes a string-like shape, and a solution has been desired.
本発明によれば、弾性素材からなる特定の構造を備える蓋にて、シリンジ先端部及びノズル先端部の両方に対して蓋として用いるとこができ、シリンジ先端部やノズル先端部と密着性が良く、空気等の影響によるペースト性状や種々の特性の劣化及び不十分な封鎖状態によるペーストの流出等の問題を引き起こすことなく保管できることから優れた密閉性を有している。
これにより挿入又は取外し等の操作がより行い易くなることに加え、それぞれの先端部から取外した時にチェアユニットや補助台の上に放置する場合や床に落下させた場合における蓋を見付けるための識別性がより向上する。本発明の蓋は破棄する必要もないために環境への負荷も低減することができ、また包装材料の部品数も少なくなることからコスト面においても有用である。According to the present invention, a lid having a specific structure made of an elastic material can be used as a lid for both the syringe tip and the nozzle tip, and has good adhesion to the syringe tip and the nozzle tip. It has excellent sealing properties because it can be stored without causing problems such as paste properties due to the influence of air or the like, deterioration of various properties, and outflow of paste due to insufficient sealing.
This makes it easier to perform operations such as insertion or removal, and identification to find a lid when left on a chair unit or auxiliary stand when removed from the tip or when dropped on the floor. More improved. Since the lid of the present invention does not need to be discarded, the burden on the environment can be reduced, and the number of parts of the packaging material is reduced, which is useful in terms of cost.
