【0024】
この実施の形態にかかる試験管2によれば、検体情報を記憶するRFIDタグ10を挿入可能な差込部8を有するため、試験管2の使用が終了した場合には、RFIDタグ10を差込部8から取り外し再利用することができる。従って、検査等に用いるRFIDタグ付試験管のコストの低減を図ることができる。
【0025】
また、この実施の形態にかかる試験管2によれば、差込部8が収容部4の上部外周部に設けられているため、RFIDタグ10を装着した時においても、試験管2の収容部4に収容された検体の状態を容易に確認することができる。
【0026】
また、この実施の形態にかかる試験管2によれば、差込部8がRFIDタグ10を収容部4の外周部に沿って挿入可能な挿入口8aを有するため、装置により又は、手作業によりRFIDタグ10を差込部8に容易に装着し又は取り外すことができる。
【0027】
また、この実施の形態にかかる試験管2の差込部8にRFIDタグ10が差し込まれた場合には、試験管2に収容された検体と該検体の検体情報を一体として管理し、取り扱うことができる。
【0028】
次に、この発明の実施の形態にかかる試験管を用いた分注システムについて説明する。図4は、実施の形態にかかる分注システムの概略構成図である。この分注システムは、分注装置20により元検体用検体容器22に収容されている検体を、検体ラック24に収容されている分注検体用検体容器26に分注するものである。
【0029】
分注装置20は、水平方向及び垂直方向に移動可能な分注ヘッド20aを有しており、分注ヘッド20aには、元検体用検体容器22に備えられているRFIDタグ(第1のRFIDタグ)22a及び分注検体用検体容器26に備えられているRFIDタグ(第1のRFIDタグ)26aとの間で情報の送受信を行うためのアンテナ(第1のアンテナ)20bが設けられている。
【0030】
ここでアンテナ20bは、リング状の形状を有しており、分注ヘッド20aの先端部近傍に設けられている。なお、アンテナ20bには、元検体用検体容器22又は分注検体用検体容器26に分注ヘッド20aが挿入されたときに、元検体用検体容器22又は分注検体用検体容器26に設けられているRFIDタグとの間で情報の送受信が可能となるように通信距離を調整するための形状(例えば、所定の幅を有するリング状の形状)が付与されている。また、分注装置20には、検体ラック24に備えられているRFIDタグ(第2のRFIDタグ)24a、即ち検体指示情報記憶手段との間で情報の送受信を行うためのアンテナ(第2のアンテナ)20cが設けられている。
【0031】
元検体用検体容器22は、図1に示す試験管により構成されており、RFIDタグ22aには、元検体用検体容器22に収容されている検体の検体情報(受付日、検体ID)が記憶されている。また、分注検体用検体容器26は、図1に示す試験管により構成されており、RFIDタグ26aには、分注検体用検体容器26に収容される検体の検体情報が記憶される。
【0032】
検体ラック24には、RFIDタグ24aが備えられている。このRFIDタグ24aには、電磁誘導方式のRFIDタグが用いられる。この電磁誘導方式のRFIDタグは、主に250KHz以下、あるいは13.56MHz帯の長・中波長の電磁波を利用する。電磁誘導方式のRFIDタグのアンテナとしてはコイルを用い、2つのコイルの誘導磁束による誘起電圧を利用して情報の送受信を行う。この電磁誘導方式のRFIDタグには、記憶できる情報量が数バイトのものから数百バイトのものまで存在する。このRFIDタグ24aにはラベル形又はカード形が用いられる。このRFIDタグ24aには、検体ラック24に収容される分注検体に関する検体指示情報が記憶される。
【0033】
図5は、分注装置20のブロック構成図である。この分注装置20は、分注装置の全体を制御する制御部30を備えている。この制御部30には、分注ヘッド20aの駆動制御を行う分注ヘッド駆動部32及び検体の吸引、吐出を行うためのポンプ34が接続されている。
【0034】
また、制御部30には、RFIDタグ22a又はRFIDタグ26aとの間で情報の読み取り書き込みを行う第1タグ読取書込装置36を介してアンテナ20bが接続されており、また、RFIDタグ24aとの間で情報の読み取り書き込みを行う第2タグ読取書込装置38を介してアンテナ20cが接続されている。更に検体情報等を記憶する記憶部40が接続されている。
【0035】
次に、図6のフローチャートを参照して実施の形態に係る検体の分注処理について説明する。まず、図7(a)に示すように、制御部30からの制御信号に基づいて、分注ヘッド駆動部32により分注ヘッド20aを駆動し、元検体用検体容器22上に移動させ、更に元検体用検体容器22の収容部内に分注ヘッド20aを挿入する(ステップS10)。
【0036】
分注ヘッド20aが元検体用検体容器22の収容部内に挿入されると、アンテナ20bにより、元検体用検体容器22に備えられているRFIDタグ22aから送信される検体情報を受信し、第1タグ読取書込装置36により検体情報を読み取る(ステップS11)。そして、この読み取った検体情報を記憶部40に記憶する(ステップS12)。次に、制御部30からの制御信号に基づいて、ポンプ34により元検体用検体容器22に収容されている元検体を必要量だけ吸引する。
【0037】
次に、図7(b)に示すように、制御部30からの制御信号に基づいて、分注ヘッド駆動部32により分注ヘッド20aを駆動し、検体ラック24に収容されている所定の分注検体用検体容器26上に移動させ、更に分注検体用検体容器26の収容部内に分注ヘッド20aを挿入する(ステップS14)。
【0038】
分注ヘッド20aが分注検体用検体容器26の収容部内に挿入されると、第1タグ読取書込装置36を介してアンテナ20bにより、分注検体用検体容器26に備えられているRFIDタグ26aに対して、記憶部40に記憶されている元検体の検体情報を送信し、RFIDタグ26aに対して検体情報を書き込む(ステップS15)。次に、制御部30からの制御信号に基づいて、ポンプ34を制御し分注検体用検体容器26内に吸引した検体を吐出する(ステップS16)。
【0039】
次に、分注を行った分注検体用検体容器26の検体ラック24上の位置情報と、この分注検体用検体容器26のRFIDタグ26aに書き込まれた検体情報を結び付けた(紐付けた)検体指示情報を作成し、記憶部40に記憶する(ステップS17)。そして、分注する必要のあるすべての検体について分注が終了したか否かの判断を行い(ステップS18)、まだ分注すべき検体が残っている場合には、ステップS10に戻って、次の検体の分注処理を行う(ステップS10〜ステップS17)。
【0040】
ステップS18において、分注する必要のあるすべての検体について、分注処理が終了したと判断された場合には、分注検体用検体容器26が収容されている検体ラック24のラック番号と、この検体ラック24に収容されている検体の検体指示情報を記憶部40から読み出し、検体ラック24に備えられているRFIDタグ24aに書き込む。即ち、第2タグ読取書込装置38を介してアンテナ20cからRFIDタグ24aに対して検体指示情報を送信し、RFIDタグ24aに対して検体指示情報を書き込む(ステップS19)。
【0041】
この実施の形態にかかる分注システムによれば、分注ヘッド20aを元検体用検体容器内22に挿入し元検体の一部を吸引する際に、アンテナ20bを介して元検体用検体容器に備えられているRFIDタグ22aに記憶されている検体情報を受信し、分注ヘッド20aを分注検体用検体容器内26に挿入し吸引した元検体を吐出する際に、アンテナ20bを介して分注検体用検体容器26に備えられているRFIDタグ26aに検体情報を送信する。従って、分注処理を行うのと同時に分注された検体の検体情報を確実にRFIDタグ26aに書き込むことができる。
【0042】
また、検体ラック24に、該検体ラック24に収容されている分注検体用検体容器26に関する検体指示情報を記憶するRFIDタグ24aを備えるため、検体ラックに収容されている分注検体用検体容器に収容されている検体の検体情報を検体と一体としてラック単位で管理することができる。更に、RFIDタグ24aが電磁誘導方式であるため記憶容量が大きく、検体ラック24の各収容部に収容されている検体の検体指示情報を一つのRFIDタグに記憶させることができる。
【0043】
なお、上述の実施の形態においては、検体情報として受付日及び検体IDを元検体用検体容器に備えられているRFIDタグ22a及び分注検体用検体容器26に備えられているRFIDタグ26aに記憶させているが、更に、検査項目名、検査材料名、患者名、性別、年齢、病院名、カルテ番号等を記憶させるようにしてもよい。
【0044】
【発明の効果】
この発明の試験管によれば、検体情報を記憶する第1のRFIDタグを挿入可能な差込部を有するため、試験管の使用が終了した場合には、第1のRFIDタグを差込部から取り外し再利用することができる。また、差込部が収容部の上部外周部に設けられているため、第1のRFIDタグを装着した時においても、試験管の収容部に収容された検体の状態を容易に確認することができる。更に、差込部が第1のRFIDタグを収容部の外周部に沿って挿入可能な挿入口を有するため、装置により又は、手作業により第1のRFIDタグを差込部に容易に装着し又は取り外すことができる。また、試験管に収容された検体と該検体の検体情報を一体として管理することができる。
【0045】
また、この発明の分注システムによれば、分注ヘッドを元検体用検体容器内に挿入し元検体の一部を吸引する際に、第1のアンテナを介して元検体用検体容器に備えられている第1のRFIDタグに記憶されている検体情報を受信し、分注ヘッドを分注検体用検体容器内に挿入し吸引した元検体を吐出する際に、第1のアンテナを介して分注検体用検体容器に備えられている第1のRFIDタグに検体情報を送信する。従って、分注処理を行うのと同時に分注された検体の検体情報を容易に第1のRFIDタグに書き込むことができる。また、検体ラックに収容されている分注検体用検体容器に収容されている検体の検体指示情報を検体と一体としてラック単位で管理することができる。
