Description

この発明は、注射筒・薬剤容器間で薬剤を移送させる装置の技術に関する。 This invention relates to a technique of a device for transferring the drug across syringe-drug container.

医療施設において使用される抗癌剤等の危険性医薬品には、治療用放射性医薬品などを含め多種の製品が存在する。 The risk pharmaceuticals such as anticancer agents to be used in medical facilities, there are a wide variety of products, including such therapeutic radiopharmaceuticals. 危険性医薬品は、医療施設において治療目的に合わせて日常的に使用されている薬剤である。 Risk medicament is an agent which is routinely used in accordance with the therapeutic purposes in medical facilities. しかし、その調製や投与を行う環境で働く医療従事者の尿から、被ばくしていない医療従事者と比較し、相対的に高いレベルの変異誘発性物質が検出され、生殖面での悪影響が懸念されている。 However, from the urine of medical personnel working in environment for their preparation and administration, as compared to medical personnel which is not exposed, is detected mutagenic substances relatively high levels, concerns adverse reproductive surface It is.

米国労働衛生安全庁は、医療従事者の抗腫瘍性薬及びその他の危険性医薬品の取り扱いについてガイドラインを公表し、米国国立衛生研究所(NIH : National Institutes of Health)などの機関でも、危険性医薬品の取り扱いに関する規定が設けられている。 The US Occupational Health and Safety Agency, published the guidelines for the handling of anti-neoplastic drugs and other risk drugs of medical personnel, the United States National Institutes of Health: In (NIH National Institutes of Health) organizations such as the risk pharmaceuticals provisions regarding the handling is provided for. しかし、医療施設において危険性医薬品が取扱われる際、当該危険性医薬品により医療従事者及び患者が、意図せず被ばくする状況が未だに多く存在する。 However, when the risk medicament is handled in a medical facility, medical personnel and patients by the risk pharmaceuticals, situations where exposure still exists many unintentionally. その場合、被ばくの経路は、危険性医薬品の気体や液体の経皮又は経口によるものが多い。 In that case, the route of exposure is often due to transdermal or oral gaseous or liquid risk pharmaceuticals.

具体的には、調剤作業における薬剤容器から注射器への薬剤吸引時や、輸液バッグへの薬剤注入時などに、薬剤の漏出や滴下が生じることにより被ばくする場合が多い。 Specifically, and during drug suction from the drug container to the syringe in preparation operations, such as during drug infusion into the infusion bag, is often exposure by drug leakage and dripping occurs. 更に具体的には、漏出した薬剤が直接皮膚に触れたり、気化した薬剤又は乾燥した薬剤の粒子が空気中を浮遊し、体内へ吸入されたりすることが考えられる。 More specifically, the leaked drug or contact with skin directly, vaporized drug or dried drug particles suspended in the air, it is conceivable to or sucked into the body.

上記状況に鑑み、容器間で危険性薬剤を移送する場合、当該容器間を閉鎖系とすることによって、医療従事者及び患者の危険性薬剤による被ばくを防止する試みとして、たとえば容器間薬剤移送を行うための医療機器が提案されている(たとえば特許文献1乃至6参照。)。 In view of the above circumstances, when transferring the hazardous agent between container by a closed system between the containers, an attempt to prevent exposure to medical personnel and patients risk drug, for example a container between drug transport medical equipment for performing has been proposed (e.g. see Patent documents 1 to 6.).

また、薬剤移送時に、圧力調整機構を薬剤容器に取り付けることによって、当該薬剤容器からの危険性薬剤の漏出や滴下のリスクを軽減させることを目的として、容器内外の圧力差を減少させる試みが提案されている(たとえば特許文献4参照。)。 Further, at the time of drug transport, by attaching a pressure adjustment mechanism on the drug container, for the purpose of reducing the risk of leakage and dripping risk drug from the drug container, an attempt to reduce the pressure difference between the vessel and out proposed is (for example, see Patent Document 4.).
