Description

本発明は、陰圧操作トレーニング具に関する。   The present invention relates to a negative pressure operation training tool.

例えば、癌の化学療法に関わる薬剤師にとって、抗癌剤の注射器による調製作業を適正に行うスキルは必須と言える。
注射器による抗癌剤の調製作業は、注射器にバイアルやアンプルから薬液を抜取り、注射器のシリンジ内の空気を抜き、他のバイアルに薬液を注入して、注射針を抜針するという一連の流れで行われる。この際、バイアル内を常に陰圧状態に保ちつつバイアルから薬液を吸引又はバイアルに薬液を注入する操作（以下、陰圧操作と言う）を行う必要があった。薬剤師は、正しく陰圧操作が出来るように繰返し練習し陰圧操作を確実に習得しておくのが、薬物汚染のリスクの低減を図る上で望ましい。 For example, it can be said that a pharmacist involved in cancer chemotherapy must have the skill to properly prepare an anticancer drug with a syringe.
Preparation of anticancer drugs using a syringe is performed in a series of steps: drawing a drug solution from a vial or ampoule into a syringe, drawing air from the syringe syringe, injecting a drug solution into another vial, and then pulling out the needle. . At this time, it was necessary to perform an operation (hereinafter referred to as a negative pressure operation) for sucking the chemical solution from the vial or injecting the chemical solution into the vial while keeping the inside of the vial in a negative pressure state. In order to reduce the risk of drug contamination, it is desirable for the pharmacist to practice the negative pressure operation repeatedly so that the negative pressure operation can be performed correctly and to acquire the negative pressure operation.

陰圧操作を習得するための実習では、注射器の扱いに不慣れな経験の浅い薬剤師、あるいは、薬剤師の卵が注射器を扱う為、例えば、バイアルから注射針を抜く際に薬液が飛散したり、注射器の空気を抜く際に薬液が滴下したりすることがあった。
そこで、無害の実習用薬液を使用する、陰圧操作のトレーニング用教材としての実習キットが提案されている（特許文献１参照）。 In the practice to learn negative pressure operation, because the inexperienced pharmacist who is unfamiliar with the handling of the syringe or the egg of the pharmacist handles the syringe, for example, when the needle is pulled out from the vial, the drug solution is scattered, In some cases, the chemical solution dropped when the air was removed.
In view of this, a training kit has been proposed as a training material for negative pressure operation training using a harmless chemical solution for training (see Patent Document 1).

陰圧操作を確実に行える薬剤師の育成が急務であり、熟練度の高いベテラン薬剤師が指導者となり、経験の浅い薬剤師、あるいは、薬剤師の卵を指導している。しかし、ベテラン薬剤師は、１人で多数（時として２０人〜４０人）の実習生を指導しなければならず、ベテラン薬剤師の指導が実習生全員に十分に行き届かないこともあった。実習生は、自分自身が陰圧操作を正しく行えているか判断できず、実習生の技術が向上しないという欠点があった。   There is an urgent need to train pharmacists who can reliably perform negative pressure operations, and highly experienced pharmacists are instructors to instruct inexperienced pharmacists or eggs of pharmacists. However, a veteran pharmacist must instruct many (sometimes 20 to 40) apprentices by himself, and the veteran pharmacist may not be able to reach all the apprentices sufficiently. The apprentice cannot judge whether he / she can perform the negative pressure operation correctly, and the apprentice's skill is not improved.

そこで、本発明は、陰圧操作の訓練を効率よく行える陰圧操作トレーニング具を提供することを目的とする。   Then, an object of this invention is to provide the negative pressure operation training tool which can perform the training of negative pressure operation efficiently.

A positive pressure notifying means for appealing to the auditory and / or visual sense that the inside of the vial is in a positive pressure state. It is comprised as a portable integral unit by the casing which has and has a display part.

また、上記バイアル内の圧力変遷を記憶する圧力記憶手段を備え、該圧力記憶手段の圧力変遷情報を取出し可能としたものである。
また、上記設定記憶手段に設定圧力領域を入力するための圧力設定手段を有しているものである。 In addition, pressure storage means for storing the pressure transition in the vial is provided, and the pressure transition information of the pressure storage means can be taken out.
Further, the apparatus has pressure setting means for inputting a set pressure region to the setting storage means.

本発明の陰圧操作トレーニング具によれば、練習者が陰圧操作の練習をする際にバイアル内が陰圧状態に保たれているか耳や目で確認できる。指導者が練習者に付き添っていなくても、１人で、正しく陰圧操作が行えているか判断することができる。従って、多数の練習者が同時に陰圧操作の練習を行える。練習者が、合同実習以外の場でも陰圧操作の練習を行うことができ、いつでも陰圧操作の練習をすることができ、空き時間を有効活用できる。   According to the negative pressure operation training tool of the present invention, it can be confirmed with the ears or eyes whether the inside of the vial is maintained in a negative pressure state when the practitioner practices the negative pressure operation. Even if the instructor is not accompanied by the practitioner, one person can determine whether the negative pressure operation is correctly performed. Therefore, many practitioners can practice negative pressure operation simultaneously. The practitioner can practice the negative pressure operation even in places other than the joint practice, and can practice the negative pressure operation at any time, and can effectively utilize the free time.
